- 摘要：ObjectiveThis study aims to investigate the effect of Liuwei Dihuangwan on the autophagy function in the hippocampus of senescence-accelerated mouse prone 8 （SAMP8） by regulating the expression of glycoprotein non-metastatic melanoma protein B （GPNMB）. Furthermore， it is designed to explore the mechanism of the method of tonifying the kidneys and replenishing essence in the treatment of Alzheimer's disease （AD）.MethodsIn experiment 1， 24 5-month-old SAMP8 mice were randomly and equally divided into the model group， and the low-， middle- and high-dose（0.59，1.18，2.36 g·kg-1） Liuwei Dihuangwan groups. At the same time， six 5-month-old senescence accelerated mouse resistant 1 （SAMR1） mice were used as the control group. The learning and memory ability was evaluated through novel object recognition experiment. Serum cortisol （Cort）， adrenocorticotropic hormone （ACTH） and urine 17-hydroxycorticosteroid （17-OHCS） levels were detected by enzyme-linked immunosorbent assay （ELISA）. The ultrastructure of hippocampal neurons was observed by transmission electron microscope （TEM）， and the expression levels of hippocampal GPNMB， a disintegrin and metalloproteinase 10 （ADAM10） and autophagy-related proteins were detected by Western blot. In experiment 2， 18 SAMP8 mice were randomly and equally divided into the model group， vector control group （Vector）， and GPNMB overexpression group （GPNMBOE）. Lentiviral vectors were stereotactically injected into the brain （2 μL per side in the GPNMBOE group）. Western blot was used to detect the expression of the above target proteins in the hippocampus； In Experiment 3， 24 SAMP8 mice were randomly and equally divided into the model group， Liuwei Dihuangwan group， Liuwei Dihuangwan+negative control （NC） group， and Liuwei Dihuangwan+GPNMB silencing group （shGPNMB）. Before drug treatment， the Liuwei Dihuangwan+NC group and the Liuwei Dihuangwan+shGPNMB group were injected with negative control and GPNMB silencing lentivirus， respectively. Western blot was used to detect the expression of the above target proteins in the hippocampus.ResultsThe novel object discrimination index of mice in the model group was significantly lower than that of mice in the control group （P<0.01）. The novel object discrimination index of mice in the medium- and high-dose Liuwei Dihuangwan groups was significantly higher than that of mice in the model group （P<0.01）. Aggregated autolysosomes were observed in the normal hippocampus tissue by TEM. In the model group， mitochondria were dominant， and no typical characteristic autophagosomes were observed. In the low- and medium-dose Liuwei Dihuangwan groups， a small number of autolysosomes and autophagosomes with double-membrane structures were observed. In the high-dose Liuwei Dihuangwan group， the number of autophagosomes and autolysosomes was greater than that in the low- and medium-dose groups. The results of ELISA and Western blot showed that compared with the control group， the levels of serum Cort， ACTH， and urine 17-OHCS in the model group were substantially increased， while the expression of hippocampal ADAM10， Beclin1， and microtubule associated-protein light chain 3-Ⅱ/Ⅰ （LC3 Ⅱ/Ⅰ） was significantly decreased. The expression of GPNMB and ubiquitin binding protein p62 was significantly increased （P<0.05， P<0.01）. Compared with the model group， the serum Cort and ACTH levels in the low-， medium-， and high-dose Liuwei Dihuangwan groups were significantly reduced， while only the urine 17-OHCS level in the high-dose group was significantly reduced. The hippocampal GPNMB， ADAM10， Beclin1， and LC3 Ⅱ/Ⅰ expression levels in the medium-， and high-dose groups of Liuwei Dihuangwan were significantly increased compared to the model group， whereas the expression of p62 was significantly reduced （P<0.01）. The above indicators showed a progressive trend among the three groups. Compared with the model group， the GPNMBOE group showed a significant increase in GPNMB， ADAM10， Beclin1， LC3 Ⅱ/Ⅰ expression， and a significant decrease in p62 expression （P<0.01）. Compared with the model group， the expression of GPNMB， ADAM10， Beclin1， and LC3 Ⅱ/Ⅰ in the hippocampus of the Liuwei Dihuangwan group significantly increased， while the expression of p62 significantly decreased （P<0.01）. Compared with the Liuwei Dihuangwan group， the Liuwei Dihuangwan+shGPNMB group showed a significant decrease in GPNMB， ADAM10， Beclin1， LC3 Ⅱ/Ⅰ， and a significant increase in p62 expression （P<0.01）.ConclusionLiuwei Dihuangwan can enhance hippocampal autophagy function and improve AD by upregulating GPNMB expression.关键词：Alzheimer's disease;Liuwei Dihuangwan;glycoprotein non-metastatic melanoma protein B （GPNMB）;autophagy;tonify the kidneys and replenish essence187|78|0更新时间：2026-05-29
- 摘要：ObjectiveThis paper aims to investigate the mechanism by which Erchentang improves body weight in obese mice by regulating the AMP‑activated protein kinase （AMPK）/peroxisome proliferator‑activated receptor γ coactivator‑1α （PGC‑1α） signaling pathway and inducing browning of inguinal white adipose tissue （iWAT）.MethodsObese mouse models were established by feeding a high‑fat diet. After successful modeling， mice were randomly divided into a model group and low‑， medium‑， and high‑dose Erchentang groups （7.5， 15， 30 g·kg-1）， with six mice in each group. Another six normal mice were set as the normal group. Mice in the treatment groups were administered with corresponding doses of the drug by gavage， while those in the normal and model groups were administered with an equal volume of pure water by gavage for four consecutive weeks. Obesity was evaluated by body weight and Lee's index. The levels of low‑density lipoprotein cholesterol （LDL‑C） and high‑density lipoprotein cholesterol （HDL‑C） in serum were detected by biochemical assays. The leptin content in serum was measured by enzyme‑linked immunosorbent assay （ELISA）. Hematoxylin and eosin （HE） staining was used to observe the pathological morphology of the liver and iWAT. Immunofluorescence staining was applied to detect the protein expression levels of glucose transporter 4 （GLUT4） in the liver and iWAT. Molecular docking was performed to simulate the binding affinity between the key components of Erchentang （nobiletin， diosmetin， naringenin） and the key pathway proteins AMPK and PGC‑1α. Western blot was used to detect the protein expression levels of uncoupling protein‑1 （UCP‑1）， AMPK， phosphorylated AMP-activated protein kinase （p‑AMPK）， and PGC‑1α in iWAT.ResultsCompared with those in the normal group， the mice in the model group showed significantly increased body weight and Lee's index， elevated levels of HDL‑C， LDL‑C， and leptin in serum， enlarged adipocytes in iWAT， down‑regulated protein expression levels of GLUT4 in iWAT and liver， and decreased protein expression levels of UCP‑1 and PGC‑1α in iWAT（P<0.05， P<0.01）， the expression level of p-AMPK / AMPK protein was up-regulated， but the difference was not statistically significant. Compared with those in the model group， the mice in the Erchentang groups with different doses exhibited significantly reduced body weight and Lee's index， decreased levels of HDL‑C， LDL‑C， and leptin in serum， smaller adipocytes in iWAT， up‑regulated GLUT4 protein expression levels in iWAT and liver， and increased protein expression levels of UCP‑1， p‑AMPK/AMPK， and PGC‑1α in iWAT （P<0.05， P<0.01）. Molecular docking results show that nobiletin， diosmetin， and naringenin have strong binding energies with both AMPK and PGC‑1α.ConclusionErchentang may improve body weight in obese mice by regulating the AMPK/PGC‑1α signaling pathway and inducing iWAT browning.关键词：obesity;traditional Chinese medicine;Erchentang;browning of white adipose tissue;AMP‑activated protein kinase （AMPK）/peroxisome proliferator‑activated receptor γ coactivator‑1α （AMPK/PGC-1α） signaling pathway92|57|0更新时间：2026-05-29
- 摘要：ObjectiveTo investigate the effects of modified Xiaoyaosan （JJXYS） on behavioral abnormalities and hippocampal mitochondrial quality control （MQC） in the rat model of post-myocardial infarction depression （PMD） and preliminarily explore its potential mechanism.MethodsA rat model of PMD was established by left anterior descending coronary artery ligation combined with chronic unpredictable mild stress （CUMS）. Rats were randomized into a control group， a model group， a fluoxetine （FLX， 10 mg·kg-1） group， and low-， medium-， and high-dose JJXYS （JJXYS-L/M/H， 1.12， 2.24， 4.48 g·kg-1， respectively） groups. Depressive-like behaviors were evaluated by body weight monitoring， sucrose preference test， open field test， and forced swimming test. Hematoxylin-eosin staining and Nissl staining were used to observe hippocampal histomorphology and neuronal changes. Enzyme-linked immunosorbent assay was conducted to determine the serum levels of 5-hydroxytryptamine （5-HT）， dopamine （DA）， interleukin-1 beta （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-alpha （TNF-α）. The mRNA levels of MQC-related genes including peroxisome proliferator-activated receptor-gamma coactivator-1 alpha （PGC-1α）， nuclear respiratory factor 1 （Nrf1）， and transcription factor A， mitochondrial （TFAM） in the hippocampal tissue were measured by real-time PCR. The expression of proteins related to the dynamin-related protein 1 （Drp1）/PTEN-induced putative kinase 1 （PINK1）/Parkin signaling pathway was determined by Western blot.ResultsCompared with the control group， the model group showed restricted body weight gain， aggravated depressive-like behaviors， declined serum 5-HT and DA levels， evident hippocampal neuronal damage and reduced Nissl bodies， as well as downregulated expression of MQC-related genes and proteins （P<0.05）. Compared with the model group， both FLX and JJXYS alleviated the above changes to varying degrees. Moreover， the JJXYS-M and JJXYS-H groups showed more pronounced effects， improving behavioral performance， restoring 5-HT and DA levels， alleviating hippocampal pathological injury， and upregulating the expression of PGC-1α/Nrf1/TFAM mRNA and Drp1/PINK1/Parkin signaling pathway-related proteins （P<0.05）.ConclusionJJXYS can significantly alleviate depressive-like behaviors and neurotransmitter imbalance in the rat model of PMD by regulating hippocampal MQC and upregulating the Drp1/PINK1/Parkin-related pathway. This study provides experimental evidence for the intervention of PMD with JJXYS.关键词：modified Xiaoyaosan;post-myocardial infarction depression;dynamin-related protein 1 （Drp1）/PTEN-induced putative kinase 1 （PINK1）/Parkin;mitochondrial quality control71|42|0更新时间：2026-05-29
- 摘要：ObjectiveTo observe the protective effect of Erchentang （ECT） on SiO2-induced lung injury in rats and to explore its underlying mechanism.MethodsA rat model of lung injury was established by a single intratracheal instillation of 50 mg·mL-1 SiO2 suspension. Thirty male Sprague-Dawley （SD） rats were randomly assigned to five groups： control， model， low and high-dose （4.5 g·kg-1·d-1 and 9 g·kg-1·d-1， respectively） ECT， and dexamethasone （0.2 mg·kg-1·d-1）. All the groups were treated for 4 consecutive weeks. Histopathological alterations in the lung tissue were examined by hematoxylin and eosin （HE） staining. The levels of malondialdehyde （MDA）， superoxide dismutase （SOD）， and glutathione peroxidase （GSH-Px） in the lung tissue were measured through biochemical assays. The expression of key molecules in the nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） pathway was determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， Western blot， and immunofluorescence assay. The primary active components of ECT were identified by ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）， and their binding affinity to Nrf2/HO-1 was assessed by molecular docking. Untargeted metabolomics of the lung tissue was performed based on UPLC-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS）， and correlation analysis was performed to identify differential metabolites and parameters closely associated with the Nrf2/HO-1 pathway.ResultsCompared with the control group， the model group exhibited a reduction in body weight gain， an increase in lung index， increased MDA content， weakened SOD and GSH-Px activities in the lung tissue， down-regulated mRNA and protein levels of Nrf2 and protein levels of HO-1 and GPX4， and an up-regulated protein level of Keap1 （P<0.05， P<0.01）. Treatment with ECT attenuated the SiO2-induced decline in body weight （P<0.05）， alleviated inflammatory cell infiltration and silicotic nodule formation in alveoli， and reduced the MDA content and enhanced the SOD and GSH-Px activities in the lung tissue （P<0.05， P<0.01）. UPLC-MS/MS and molecular docking revealed that core components of ECT， such as hesperidin and glycyrrhizic acid， displayed strong binding affinity to Nrf2/HO-1. Molecular biological experiments demonstrated that ECT promoted nuclear translocation of Nrf2， up-regulated the mRNA and protein levels of HO-1 and GPX4， and down-regulated Keap1 expression （P<0.05， P<0.01）. Metabolomic analysis indicated that ECT reversed the SiO2-induced aberrant expression of metabolites， including linoleic acid and glutamine （P<0.05， P<0.01）. Correlation analysis showed that Nrf2 and HO-1 were positively correlated with SOD and GSH-Px （P<0.05， P<0.01）， but negatively correlated with glutamine and serine （P<0.05， P<0.01）.ConclusionECT may activate the Nrf2/HO-1 pathway through its core active components， thereby regulating oxidative stress and metabolic disorders to ameliorate SiO2-induced lung injury in rats. This study provides experimental evidence for ECT in the prevention and treatment of occupational lung injury.关键词：Erchentang;SiO2;lung injury;nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） pathway;oxidative stress;metabolic disorders32|20|0更新时间：2026-05-29
- 摘要：ObjectiveTo investigate the mechanism by which Shaoyaotang regulates the miRNA-155-mediated suppressor of cytokine signaling 1 （SOCS1）/Janus kinase 1 （JAK1）/signal transducer and activator of transcription 1 （STAT1） signaling pathway and thereby affects macrophage polarization.MethodsThe cell-counting kit-8 （CCK-8） assay was used to detect the effect of drug-containing serum of Shaoyaotang at different concentrations on the viability of RAW 264.7 cells. A cell model of inflammation was established by stimulating RAW264.7 cells with lipopolysaccharide （LPS） at a concentration of 10 mg·L-1 The modeled cells were assigned by the random number table method into seven groups： LPS-induced M1 polarization （model）， M1+miRNA-155 mimics， M1+miRNA-155 inhibitor， M1+Shaoyaotang-containing serum， M1+miRNA-155 mimics+Shaoyaotang-containing serum， M1+miRNA-155 inhibitor+Shaoyaotang-containing serum， and M1+blank serum. Enzyme-linked immunosorbent assay was employed to measure the levels of inflammatory factors ［tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β）］. Immunofluorescence assay was used to detect the expression of macrophage polarization markers ［inducible nitric oxide synthase （iNOS） and macrophage mannose receptor 1 （CD206）］. Real-time PCR was employed to measure the expression of miRNA-155 in cells. Western blot was performed to determine the protein levels of SOCS1， STAT1， and JAK1.ResultsCompared with the LPS-induced M1 polarization （model） group， the M1+miRNA-155 mimics group showed up-regulated expression of miRNA-155， JAK1， STAT1， TNF-α， IL-6， IL-1β， and iNOS （P<0.05） and down-regulated expression of CD206 （P<0.05）. In both the M1+miRNA-155 inhibitor group and the M1+Shaoyaotang-containing serum group， the expression levels of miRNA-155， JAK1， STAT1， TNF-α， IL-6， IL-1β， and iNOS were down-regulated （P<0.05）， while those of SOCS1 and CD206 were up-regulated （P<0.05）. Compared with the M1+miRNA-155 mimics group， the M1+miRNA-155 mimics+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155， JAK1， STAT1， TNF-α， IL-6， IL-1β， and iNOS （P<0.05） and up-regulated expression of SOCS1 and CD206 （P<0.05）. Compared with the M1+miRNA-155 inhibitor group， the M1+miRNA-155 inhibitor+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155， JAK1， STAT1， TNF-α， IL-6， IL-1β， and iNOS （P<0.05） and up-regulated expression of SOCS1 and CD206 （P<0.05）.ConclusionShaoyaotang regulates macrophage polarization by modulating miRNA-155 expression and interfering with the SOCS1/JAK1/STAT1 signaling pathway. The findings provide new experimental evidence for the treatment of ulcerative colitis with Shaoyaotang.关键词：Shaoyaotang;miRNA-155;macrophage polarization;suppressor of cytokine signaling 1/Janus tyrosine kinase 1/signal transducer and activator of transcription 1（SOCS1/JAK1/STAT1） signaling pathway;ulcerative colitis42|48|0更新时间：2026-05-29

Except for the normal control group， mice in the other five groups were induced to establish UC models using dextran sulfate sodium （DSS）. The normal control group was administered pure water via intragastric gavage， while the other groups received intragastric gavage of mesalazine solution， intragastric gavage of Shaoyaotang， and the 2-DG group was treated with 2-DG via intraperitoneal injection. After 7 consecutive days of treatment， colonic tissues were extracted. Hematoxylin and eosin （HE） staining was performed to evaluate histopathological changes and tissue injury in the colon. Enzyme-linked immunosorbent assay （ELISA） was used to detect the expression of interleukin-10 （IL-10） and tumor necrosis factor-α （TNF-α） in colonic tissues. Western blot analysis was employed to determine the expression levels of hypoxia-inducible factor-1α （HIF-1α）， glucose transporter （GLUT1）， lactate dehydrogenase A （LDHA）， pyruvate kinase M2 （PKM2）， and 6-phosphofructo-2-kinase/fructose-2，6-biphosphatase 3 （PFKFB3） in colonic tissues. Immunofluorescence was conducted to detect the expression of CD206 and inducible nitric oxide synthase （iNOS） in colonic tissues. Liquid chromatography-mass spectrometry （LC-MS） was utilized to measure lactate and citrate levels in colonic tissues.ResultsCompared with the normal control group， mice in the model group exhibited a significant increase in disease activity index （DAI） scores， accompanied by colonic mucosal congestion， edema， and inflammatory cell infiltration， significantly elevated expression of the inflammatory cytokine TNF-α （P<0.05）， significantly decreased IL-10 expression （P<0.05）， significantly increased levels of HIF-1α， GLUT1， LDHA， PKM2， and PFKFB3 in colonic tissues （P<0.05）， markedly elevated iNOS expression （P<0.05）， significantly decreased CD206 expression （P<0.05）， and significantly elevated lactate and citrate levels in colonic tissues （P<0.05）. In contrast to the model group， the Shaoyaotang group， inhibitor group， and Shaoyaotang combined with inhibitor group demonstrated amelioration of mucosal injury in colonic tissues， markely decreased expression levels of the inflammatory cytokine TNF-α （P<0.05）， elevated IL-10 expression levels， significantly decreased expression of HIF-1α， GLUT1， LDHA， PKM2， and PFKFB3 （P<0.05）， markedly reduced iNOS expression levels （P<0.05）， significantly increased CD206 expression （P<0.05） and significantly decreased lactate and citrate levels （P<0.05）.ConclusionShaoyaotang ameliorates symptoms of DSS-induced UC in mice， and its therapeutic mechanism may be associated with regulating macrophage glycolytic reprogramming via modulation of the HIF-1α signaling pathway.关键词：ulcerative colitis;Shaoyaotang;glycolytic reprogramming;macrophages26|8|0更新时间：2026-05-29
- 摘要：ObjectiveTo investigate the role of microRNA-155-5p （miR-155-5p） in ulcerative colitis （UC） and study the molecular mechanism of Shaoyaotang in the treatment of UC by regulating miR-155-5p.MethodsForty-eight SPF-grade male C57BL/6 mice were selected and assigned via the random number table method into 6 groups （n=8）： A blank control group， a model group， a mesalazine （0.39 g·kg-1） group， a Shaoyaotang （31.08 g·kg-1） group， a Janus kinase 1 （JAK1） inhibitor （baricitinib， 10 mg·kg-1） group， and a Shaoyaotang combined with inhibitor （baricitinib 10 mg·kg-1 + Shaoyaotang 31.08 g·kg-1） group. After successful modeling of UC by gavage of 3% dextran sulphate sodium solution， each group received corresponding drug intervention for 7 days. Shaoyaotang and mesalazine were administered by gavage， and baricitinib by intraperitoneal injection. Twenty-four hours after the last administration， mice were anesthetized by intraperitoneal injection of pentobarbital sodium， and blood was collected for determination of white blood cell count and erythrocyte sedimentation rate （ESR）. Mice were then sacrificed for measurement of colon length. Hematoxylin-eosin staining was used to observe colonic pathological changes and perform pathological scoring. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to determine the relative expression of miR-155-5p in the colonic tissue， and Western blot was used to determine the protein levels of JAK1， phosphorylated JAK1 （p-JAK1）， suppressor of cytokine signaling 1 （SOCS1）， signal transducer and activator of transcription 1 （STAT1）， and phosphorylated STAT1 （p-STAT1）.ResultsCompared with the blank control group， the model group showed increased disease activity index （DAI） score and pathological score， shortened colon， upregulated relative expression of miR-155-5p and protein levels of p-JAK1 and p-STAT1， downregulated protein level of SOCS1 in the colonic tissue， prolonged time of erythrocyte sedimentation， and increased white blood cell count （P<0.01）. Compared with the model group， all drug-treated groups exhibited improvements in the above indicators （P<0.01）. Moreover， the Shaoyaotang group showed better therapeutic effects than the mesalazine group in regulating miR-155-5p expression， related protein levels， DAI score， and colonic pathological score （P<0.01）.ConclusionShaoyaotang may downregulate miR-155-5p to relieve its inhibition on SOCS1， thereby suppressing the excessive activation of the JAK1/STAT1 signaling pathway and ultimately alleviating intestinal inflammatory damage.关键词：Shaoyaotang;ulcerative colitis;microRNA-155-5p;Janus kinase1/signal transducer and activator of transcription 1（JAK1/STAT1） signaling pathway;intestinal inflammation19|5|0更新时间：2026-05-29

Western blot analysis was performed to determine the protein levels of TLR4， MyD88， and NF-κB in the colon.ResultsCompared with the blank group， the model group showed elevated DAI score （P<0.01）， reduced colon length and colon weight （P<0.01）， down-regulated protein levels of JAM-1 and claudin-1 （P<0.01）， and up-regulated protein levels of IL-8， COX-2， TLR4， MyD88， and NF-κB p65 （P<0.01） in the colon tissue. Compared with the model group， each treatment group showed decreased DAI score （P<0.05， P<0.01）， increased colon length and colon weight （P<0.05， P<0.01）， up-regulated protein levels of JAM-1 and claudin-1 （P<0.01）， and down-regulated protein levels of IL-8， COX-2， TLR4， MyD88， and NF-κB p65 （P<0.01） in the colon tissue.ConclusionShaoyaotang alleviates intestinal inflammation and intestinal mucosal damage to protect intestinal barrier integrity by regulating the TLR4/MyD88/NF-κB signaling pathway.关键词：ulcerative colitis;Shaoyaotang;Toll-like receptor 4 （TLR4）/myelodifferentiation factor 88 （MyD88）/nuclear factor κB （NF-κB）;intestinal mucosal barrier32|7|0更新时间：2026-05-29
- 摘要：ObjectiveTo investigate the molecular mechanisms by which Wenyang Jiedu granules （WYJD） alleviate influenza A virus （IAV）-induced pneumonia based on single-cell transcriptome sequencing.MethodsThirty female BALB/c mice were randomly divided into a blank control group （Control）， IAV group， and WYJD low-， medium-， and high-dose groups （WYJD-L， WYJD-M， WYJD-H； 2.925， 5.85， 11.7 g·kg-1， n=6）. Except for the Control group， all other groups were intranasally inoculated with IAV subtype H1N1 （A/PR/8/34） to establish an infection model. Two hours after modeling， drug administration was initiated and continued for 5 consecutive days， with daily monitoring of body weight and general condition. On day 6， mice were sacrificed and samples were collected. Lung index was calculated， and histopathological examination of lung tissue was performed. Lung tissues from the Control， IAV， and WYJD-H groups were subjected to single-cell transcriptome sequencing （n=3）， focusing on type I alveolar epithelial cells （AT1） to analyze changes in gene expression and signaling pathways. Western blot was used to detect the expression changes of relevant proteins to validate the single-cell sequencing results.ResultsCompared with the Control group， the IAV group exhibited significantly decreased body weight （P<0.05） and significantly increased lung index （P<0.05）. Compared with the IAV group， all WYJD-treated groups exhibited significantly increased body weight （P<0.01） and significantly decreased lung index （P<0.01）. Single-cell sequencing analysis revealed that WYJD inhibited overactivation of interferon and inflammatory signaling pathways in AT1 cells after IAV infection， including interferon-γ response， interferon-α response， tumor necrosis factor-α/nuclear factor-κB （TNF-α/NF-κB）， and interleukin-6/Janus kinase/signal transducer and activator of transcription 3 （IL-6/JAK/STAT3） pathways. Compared with the Control group， the number of AT1 cells in the IAV group showed a decreasing trend. Compared with the IAV group， the WYJD-H group showed an increasing trend， although neither difference was statistically significant. Further analysis of AT1 cell subpopulation gene expression showed that， compared with the Control group， the IAV group exhibited increased expression of pro-apoptotic genes FAS cell surface death receptor （FAS） and cyclin-dependent kinase inhibitor 1A （CDKN1A）， a significant increase in tumor protein p53 （Tp53） expression （P<0.05）， and significant decreases in expression of the AT1 marker gene advanced glycosylation end-product-specific receptor （AGER） and membrane structural gene caveolin1 （CAV1） （P<0.05， P<0.01）. Compared with the IAV group， the WYJD-H group showed significantly decreased expression of FAS， CDKN1A， and Tp53 （P<0.05， P<0.01）， and significantly increased expression of AGER and CAV1 （P<0.05， P<0.01）. Regarding interferon response-related genes， compared with the Control group， the IAV group showed increased expression of interferon-stimulated gene 15 （ISG15）， interferon-induced protein with tetratricopeptide repeats 3 （IFIT3）， signal transducer and activator of transcription 2 （STAT2）， bone marrow stromal cell antigen 2 （BST2）， and C-X-C motif chemokine ligand 10 （CXCL10）， with a significant increase in 2′，5′-oligoadenylate synthetase-like protein 1 （OASL1） （P<0.05）. Compared with the IAV group， the WYJD-H group showed significantly decreased expression of all the above genes， with highly significant differences for ISG15， IFIT3， STAT2， BST2， and OASL1 （P<0.01）， and a significant difference for CXCL10 （P<0.05）. Among inflammation-related genes， compared with the Control group， the IAV group showed significantly increased expression of intercellular adhesion molecule 1 （ICAM1）， tumor necrosis factor alpha-induced protein 3 （TNFAIP3）， keratin 8 （KRT8）， tumor necrosis factor receptor superfamily member 1A （TNFRSF1A）， and TNFRSF1B （P<0.01）， and increased expression of NFKBIA， a negative regulator of NF-κB （P<0.05）. Compared with the IAV group， the WYJD-H group showed significantly decreased expression of KRT8 and TNFRSF1B （P<0.05）， while ICAM1， NFKBIA， TNFAIP3， and TNFRSF1A showed decreasing trends without statistical significance. Western blot validation showed that， compared with the Control group， protein expression levels of ISG15， FAS， p53， and phosphorylated p65 （p-p65） in lung tissue of the IAV group were significantly increased （P<0.05， P<0.01）. Compared with the IAV group， the WYJD-H group showed significantly decreased expression of these proteins （P<0.05， P<0.01）.ConclusionWYJD may alleviate viral pneumonia by targeting gene expression in AT1 cells， inhibiting overactivated interferon and inflammatory signaling pathways after IAV infection， and downregulating pro-apoptotic signaling， thereby reducing alveolar epithelial injury.关键词：single-cell transcriptomics;type Ⅰ alveolar epithelial cell;interferon;inflammation;viral pneumonia31|5|0更新时间：2026-05-29
- 摘要：ObjectiveTo explore the establishment of a rat model of diabetic macrovascular atherosclerosis （DMA） with Qi and Yin deficiency syndrome induced by high-fat diet， streptozotocin （STZ）， and Yin-depleting herbs， and to evaluate its biological characteristics.MethodsForty SD rats were randomly divided into a blank group （n=10） and a modeling group （n=30）. Except for the blank group， rats in the model group were fed a high-fat diet for 4 weeks， followed by intraperitoneal injection of STZ （30 mg·kg-1） to establish a diabetic model. Twenty-four successfully modeled diabetic rats were randomly divided into a model group （n=7）， a Qi and Yin deficiency syndrome group （n=8）， and a counter-syndrome group （n=9）. Except for the model group， rats received intragastric administration of Yin-depleting herbs （1.2 g·kg-1） for 8 weeks. The counter-syndrome group was further treated with Shenqi compound formula （1.69 g·kg-1） for an additional 8 weeks. General condition and body weight were recorded， and syndrome-related indicators were assessed， including precordial temperature， skin moisture content， grip strength， open-field test performance， and tongue appearance. Serum levels of vascular endothelial growth factor （VEGF）， endothelin-1 （ET-1）， vascular cell adhesion molecule-1 （VCAM-1）， insulin-like growth factor-1 （IGF-1）， and monocyte chemotactic protein-1 （MCP-1） were measured by enzyme-linked immunosorbent assay （ELISA）. Fasting blood glucose， blood lipids， hemorheological parameters， and coagulation function were analyzed using an automatic biochemical analyzer. Vascular ultrasound and hematoxylin-eosin （HE） staining were used to evaluate vascular lesions.ResultsIn terms of syndrome manifestations， compared with the blank group， body weight increased rapidly during the first 5 weeks in the model， Qi and Yin deficiency， and counter-syndrome groups. After STZ injection combined with Yin-depleting herbal administration at week 5， body weight decreased significantly （P<0.01） and continued to decline until the end of the experiment. Rats exhibited decreased activity， irritability， coarse and yellowish fur with obvious shedding， polydipsia， polyphagia， frequent urination， and dry stools， which were most pronounced in the Qi and Yin deficiency group. Grip strength decreased， peak activity time occurred earlier， total distance in the open-field test was reduced， and residence time was prolonged. Precordial temperature decreased （P<0.01）， while paw temperature increased （P<0.05）， and skin moisture and oil content were reduced （P<0.05， P<0.01）. In terms of disease-related indicators， compared with the blank group， fasting blood glucose was significantly increased （>16.7 mmol·L-1） in the model and Qi and Yin deficiency groups， and blood lipid levels were significantly elevated （P<0.05）. Vascular-related factors ET-1， MCP-1， VCAM-1， and VEGF were significantly increased （P<0.05，P<0.01）， while IGF-1 was significantly decreased （P<0.01）. Pathological examination of the aortic valve showed valvular thickening and structural disorganization. Carotid artery examination revealed discontinuity of the intima， foam cell accumulation beneath the intima， disordered smooth muscle arrangement， and widened intercellular spaces. Compared with the model group， ET-1， MCP-1， and VEGF levels were significantly decreased in both the Qi and Yin deficiency group and the counter-syndrome group. The reductions in ET-1 and MCP-1 were more pronounced in the Qi and Yin deficiency group （P<0.01）， while the decrease in VCAM-1 was more significant in the counter-syndrome group （P<0.05）. Compared with the blank group， the Qi and Yin deficiency group showed significantly prolonged activated partial thromboplastin time （APTT）， thrombin time （TT）， and prothrombin time （PT） （P<0.01）. The erythrocyte deformability index （TK）， erythrocyte sedimentation rate， erythrocyte electrophoresis index， and whole blood low-shear viscosity all showed increasing trends. Vascular ultrasound revealed reduced arterial blood flow velocity， increased vascular resistance， and intimal thickening without plaque formation. The aortic intima showed no obvious overall thickening， with only occasional localized thickening and foam cell presence， and carotid artery injury was observed.ConclusionA rat model of DMA with Qi and Yin deficiency syndrome was successfully established using high-fat diet feeding combined with STZ injection and Yin-depleting herbal administration. Shenqi compound formula effectively alleviated Qi and Yin deficiency syndrome， regulated glucose and lipid metabolism， improved hemorheological and coagulation function， reduced vascular lesion severity， and demonstrated potential for early prevention and treatment of DMA.关键词：diabetic macroangiopathy;Qi and Yin deficiency syndrome;disease-syndrome combination;streptozotocin （STZ）34|51|0更新时间：2026-05-29
- 摘要：ObjectiveTo investigate the mechanism by which Jianpi Xiao'ai prescription （JPXAP） inhibits colorectal cancer progression by regulating the inducible nitric oxide synthase-arginase 1 （iNOS-ARG1） metabolic axis and inducing mitochondrial reactive oxygen species （mito-ROS）-mediated mitochondrial structural and functional impairment.MethodsAn arginine metabolism disorder model of human colorectal cancer HCT116 cells was established by combined treatment with recombinant human interferon-γ （IFN-γ， 10 μg·L-1） and N（ω）-hydroxy-L-arginine （Nor-NOHA， 200 μmol·L-1） for 24 h， followed by intervention with 5%， 10%， or 20% JPXAP-containing serum. Cell proliferation was assessed using cell counting kit-8 （CCK-8）， 5-ethynyl-2′-deoxyuridine （EdU） staining， and colony formation assays. Cell invasion and migration were evaluated using Transwell chamber and wound healing assays. Mitochondrial membrane potential （MMP） and ROS levels were assessed by JC-1 and MitoSOX staining， respectively. Mitochondrial ultrastructure was observed by transmission electron microscopy （TEM）. The expression of iNOS， ARG1， and mitochondrial dynamics-related proteins， including mitofusin 2 （MFN2） and dynamin-related protein 1 （DRP1）， was analyzed by Western blot and immunofluorescence. The levels of L-arginine， citrulline， and urea were determined by colorimetric methods and enzyme-linked immunosorbent assay （ELISA）.ResultsCompared with the blank group， the model group exhibited significantly upregulated iNOS expression， downregulated ARG1 expression， a decreased ARG1/iNOS ratio， reduced L-arginine and urea levels， and increased citrulline levels （P<0.05）. Meanwhile， mito-ROS accumulation was significantly increased， the JC-1 red/green fluorescence ratio was decreased， and mitochondria showed swelling and cristae disruption， indicating that metabolic disorder induced mitochondrial injury. Compared with the model group， all JPXAP-treated groups further decreased the ARG1/iNOS ratio， enhanced nitric oxide （NO） and reactive nitrogen species accumulation， further reduced L-arginine and urea levels， and increased citrulline levels （P<0.01）. EdU-positive rate， colony formation rate， wound healing rate， and Transwell invasion number all decreased significantly with increasing serum concentration （P<0.01）. Mito-ROS levels were further elevated， and the JC-1 red/green ratio further decreased. TEM revealed aggravated mitochondrial swelling and vacuolization. MFN2 expression was downregulated and DRP1 expression was upregulated （P<0.01），in a dose-dependent manner.ConclusionJPXAP further activates NO-mediated oxidative/nitrosative stress under arginine metabolism imbalance， inducing mito-ROS accumulation， MMP collapse， and mitochondrial dynamics imbalance， thereby inhibiting colorectal cancer cell proliferation and migration. These findings reveal an antitumor mechanism of JPXAP based on coordinated targeting of the "metabolism-mitochondria" axis.关键词：Jianpi Xiao'ai prescription;colorectal cancer;inducible nitric oxide synthase-arginase 1 （iNOS-ARG1）;arginine metabolism;mitochondrial dysfunction27|5|0更新时间：2026-05-29
- 摘要：ObjectiveThis paper aims to investigate the effect and mechanism of Runmu Xiaoyao powder on mice with dry eye and the syndrome of liver depression-heat syndrome based on the toll-like receptor 4 （TLR4）/myeloid differentiation primary response protein 88 （MyD88）/nuclear factor-κB （NF-κB） signaling pathway.MethodsSixty-six C57BL/6J female mice were randomly divided into a normal group， a model group， a sodium hyaluronate group， and high-， medium-， and low-dose Runmu Xiaoyao powder groups， with 11 mice per group. Except for those in the normal group， mice in the other groups were subjected to mouse models with dry eye and liver depression-heat syndrome by instilling a benzalkonium chloride solution and applying chronic pain stimulation in a dry environment. After modeling， mice in the high-， medium-， and low-dose Runmu Xiaoyao powder groups were administered intragastrically with 29.7， 14.85， 7.43 g·kg-1， respectively， twice a day for 14 consecutive days. The mice in the sodium hyaluronate group received 5 μL of sodium hyaluronate eye drops in each eye twice daily. The mice in the normal and model groups were administered intragastrically with an equal volume of deionized water. Measurements were taken of tear secretion in mice， irritability scores， corneal fluorescein staining， and histopathological changes in the cornea， lacrimal glands， meibomian glands， and liver tissue. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of interleukin-1β （IL-1β） and tumour necrosis factor-α （TNF-α） in serum. Immunohistochemistry （IHC） was used to detect the protein expression of IL-1β and TNF-α in corneal and lacrimal gland tissues. Real-time quantitative polymerase chain reaction（Real-time PCR） and Western blot were employed to detect the mRNA and protein expressions of TLR4， MyD88， and NF-κB p65 in corneal， lacrimal gland， and meibomian gland tissues.ResultsCompared with those in the normal group， mice in the model group exhibited significantly reduced tear secretion， significantly higher irritability scores， and more pronounced corneal fluorescence staining， with marked pathological damage observed in the cornea， lacrimal glands， meibomian glands， and liver tissue. IL-1β and TNF-α levels in serum were significantly elevated. The protein expressions of IL-1β and TNF-α in corneal and lacrimal gland tissues， as well as the mRNA and protein expressions of TLR4， MyD88， and NF-κB p65 in corneal， lacrimal gland， and meibomian gland tissues， were all significantly increased （P<0.01）. Compared with the model group， the sodium hyaluronate group and Runmu Xiaoyao powder groups with different doses exhibited increased tear secretion to varying degrees， alleviated corneal fluorescence staining and histopathological damage， reduced IL-1β and TNF-α levels in serum， and downregulated protein expressions of IL-1β and TNF-α in corneal and lacrimal gland tissues， as well as the mRNA and protein expressions of TLR4， MyD88， and NF-κB p65 in corneal， lacrimal gland， and meibomian gland tissues. The high-dose Runmu Xiaoyao powder group demonstrated a more pronounced effect， with multiple indicators showing superior results compared to those in the sodium hyaluronate group （P<0.05， P<0.01）.ConclusionRunmu Xiaoyao powder down-regulates the TLR4/MyD88/NF-κB signaling pathway activity in the cornea， lacrimal glands， and meibomian glands of model mice with dry eye and liver depression-heat syndrome， thereby suppressing inflammatory responses and mitigating ocular surface tissue damage. The therapeutic effect is dose-dependent， and the high-dose group exerts the most prominent effect.关键词：dry eye;liver depression-heat syndrome;Runmu Xiaoyao powder;inflammatory cytokine;ocular surface damage;toll-like receptor 4/myeloid differentiation primary response protein 88/nuclear factor-κB （TLR4/MyD88/NF-κB） signaling pathway25|8|0更新时间：2026-05-29
- 摘要：ObjectiveTo explore the effects and mechanism of the modified Danggui Yinzi on "itch-anxiety" model rats of chronic urticaria （CU）.MethodsThe 36 SPF-grade 6-8-week-old female SD rats were randomly divided into a blank control group，a model group，a positive control group，a low-dose modified Danggui Yinzi group，a medium-dose modified Danggui Yinzi group，and a high-dose modified Danggui Yinzi group. A "itch-anxiety" model was established by intraperitoneal injection of a suspension of sodium chloride and aluminum hydroxide and ovalbumin，combined with chronic unpredictable emotional stress stimulation. After successful modeling，rats in each group were administered drugs by gavage. The positive control group was given intragastric administration of the drug solutions of cetirizine and fluoxetine （2.08 mg·kg-1·d-1 fluoxetine， 2 mg·kg-1·d-1 cetirizine）， the low-，medium-，and high-dose modified Danggui Yinzi groups were administered traditional Chinese medicine at 1.44，2.88， 5.76 g·kg-1， respectively，while the blank control group and model group were given an equal volume of normal saline. All interventions lasted for 15 days. Behavioral changes were evaluated by the elevated plus-maze test （detecting the percentage of entries into the open arms （OE%），the percentage of time spent in the open arms （OT%），and the total number of entries into the open and closed arms （TNE）），the open-field test （detecting total activity，average movement speed，and latency to enter the central area），and scratching behavior observation. Pathological changes of skin tissues were observed by hematoxylin-eosin （HE） staining and toluidine blue staining，while those of amygdala tissues were observed by HE staining，Nissl staining，and immunofluorescence detection of ionized calcium-binding adapter molecule-1 （Iba-1）. The content of immunoglobulin E （IgE），interleukin-33 （IL-33），histamine in serum and glutamate in the amygdala was detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the protein expression of striatal-enriched protein tyrosine phosphatase （STEP），N-methyl-D-aspartate receptor subunit 2B （NR2B）， calmodulin-dependent protein kinase Ⅱ （CaMKⅡ），phosphorylated CaMKⅡ （p-CaMKⅡ），mitogen-activated protein kinase （MAPK），phosphorylated MAPK （p-MAPK），nuclear factor kappa-light-chain-enhancer of activated B cells （NF-κB），phosphorylated NF-κB （p-NF-κB），and postsynaptic density protein-95 （PSD-95） in the amygdala.ResultsCompared with the blank control group，the model group rats showed obvious anxiety-like behaviors （decreased OE%，OT%，and TNE，reduced total activity，slower average movement speed，and prolonged latency to enter the central area），increased scratching times，obvious skin inflammation and mast cell degranulation，severe amygdala tissue damage，increased glutamate content in the amygdala，and elevated levels of IgE and IL-33 in serum. The expression of STEP，NF-κB，p-NF-κB，NR2B，MAPK，p-MAPK，CaMKⅡ，and p-CaMKⅡ proteins in the amygdala increased，while the expression of PSD-95 protein decreased （P<0.05）. Compared with the model group，the modified Danggui Yinzi group of each dose had increased OE%，OT%，TNE，total activity，and average movement speed，shortened latency to enter the central area， reduced scratching times，alleviated skin inflammation and mast cell degranulation，relieved amygdala tissue damage，decreased glutamate content in the amygdala，and reduced levels of IgE and IL-33 in serum. Moreover，compared with the model group，the low -，medium-，and high-dose modified Danggui Yinzi groups showed decreased expression levels of STEP，NF-κB，p-NF-κB，NR2B，MAPK，p-MAPK，CaMKⅡ，and p-CaMKⅡ proteins in the amygdala，and increased expression of PSD-95 protein. There was a significant dose-effect relationship，with the high-dose group showing the most significant regulatory effect （P<0.05）.ConclusionThe modified Danggui Yinzi has a therapeutic effect on "itch-anxiety" model rats of CU. Its mechanism may be related to regulating glutamate metabolism in the amygdala，modulating the STEP/NR2B/CaMKⅡ/MAPK/NF-κB pathway，and regulating the expression of PSD-95.关键词：chronic urticaria;itch-anxiety cycle;modified Danggui Yinzi;amygdala;glutamate17|5|0更新时间：2026-05-29

- 摘要：ObjectiveTo investigate the effects and underlying mechanisms of polydatin in delaying the progression of colitis-associated colorectal cancer （CAC） by constructing an azoxymethane （AOM）/dextran sulfate sodium （DSS）-induced CAC mouse model and conducting in vitro experiments.MethodsFifty-four male C57BL/6J mice were randomly divided into normal， model， and polydatin groups （0.045 g·kg-1）. The CAC mouse model was established using AOM/DSS， and samples were collected at 4， 7， and 10 weeks. Body weight change rate， disease activity index （DAI）， and tumor formation were assessed. Hematoxylin-eosin （HE） staining was used to observe pathological injury in intestinal tissues. Immunohistochemistry （IHC） was performed to detect zonula occludens-1 （ZO-1） expression in colonic tissues， and Western blot was used to detect the expression of E-cadherin， N-cadherin， and Vimentin in colonic epithelial cells. Real-time PCR was used to measure mRNA expression of interleukin-17A （IL-17A）， Wnt3a， β-catenin， T cell factor 1 （Tcf1）， E-cadherin， N-cadherin， and Vimentin in colonic tissues. Flow cytometry was used to analyze the proportion of CD8+T cells and the expression of exhaustion-related molecules in tumors. Human colon cancer DLD-1 cells were cultured in a polydatin-containing medium， and wound healing assays were performed to observe migration changes. Real-time PCR was used to detect mRNA expression of interleukin-17 receptor A （IL-17RA）， Wnt3a， β-catenin， Tcf1， E-cadherin， N-cadherin， and Vimentin in DLD-1 cells.ResultsCompared with the normal group， the model group at all three time points showed significantly decreased body weight change rate （P<0.01）， significantly shortened colon length （P<0.01）， and markedly increased DAI scores （P<0.01）. HE staining revealed significant inflammatory cell infiltration in the submucosa of the colon in the model group， accompanied by epithelial dysplasia. ZO-1 expression in colonic tissues was significantly reduced （P<0.01）. The mRNA expression of the pro-inflammatory factor IL-17A and key molecules of the Wnt/β-catenin pathway （Wnt3a， β-catenin， Tcf1） was significantly elevated （P<0.05）. The mRNA and protein expression of epithelial-mesenchymal transition （EMT） markers N-cadherin and Vimentin was significantly upregulated （P<0.05）， while E-cadherin expression was significantly downregulated （P<0.05）. The proportion of tumor-infiltrating CD8+T cells expressing immunosuppressive molecules （TIM-3， LAG-3， PD-1） was significantly increased （P<0.05）. Compared with the model group， the polydatin group showed significant improvement in body weight and DAI score （P<0.01）， as well as recovery of colon length and tissue injury. ZO-1 expression in colonic tissue was significantly increased （P<0.01）， while IL-17A， Wnt3a， β-catenin， Tcf1， N-cadherin， and Vimentin expression levels were significantly decreased （P<0.05）， and E-cadherin expression was significantly increased （P<0.01）. Tumor-infiltrating CD8+ T cells expressing immunosuppressive molecules were significantly reduced （P<0.05）. In vitro experiments showed that polydatin significantly inhibited migration of DLD-1 cells （P<0.01） and reversed the upregulation of IL-17RA， Wnt3a， β-catenin， N-cadherin， and Vimentin mRNA， as well as the downregulation of E-cadherin mRNA （P<0.05）.ConclusionPolydatin inhibits IL-17A secretion and IL-17RA expression， improves the immune microenvironment， blocks activation of the Wnt/β-catenin signaling pathway， suppresses EMT markers （N-cadherin and Vimentin）， and restores tight junction protein expression in intestinal epithelial cells， thereby delaying the progression from colitis to colorectal cancer in mice.关键词：colitis-associated colorectal cancer;epithelial-mesenchymal transition;polydatin;interleukin-17A （IL-17A）;Wnt/β-catenin signaling pathway32|6|0更新时间：2026-05-29
- 摘要：ObjectiveThis paper aims to investigate the role of NDC80 kinetochore complex component （NUF2） and magnesium homeostasis in ovarian cancer cell apoptosis， as well as the regulatory mechanism of gypenoside L （Gyp-L） on NUF2 and magnesium homeostasis.MethodsOvarian cancer OVCAR3 cells were divided into a blank control group， a low-concentration Gyp-L group （50 µmol·L-1）， a high-concentration Gyp-L group （100 µmol·L-1）， and a cisplatin （15 µmol·L-1） group. The migration， proliferation， and apoptosis capabilities of OVCAR3 cells were evaluated through cell scratch assays， clonal experiments， and terminal-deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay （TUNEL） staining. Differentially expressed genes of ovarian cancer were screened by using the Gene Expression Omnibus （GEO） database. The interaction relationships of differentially expressed genes and proteins were analyzed via the Search Tool for Recurring Instances of Neighbouring Genes （STRING） database. The prognostic survival analysis was performed by using the Tumor Immune Estimation Resource （TIMER） database， and the differential expression levels of genes were validated with the Gene Expression Profiling Interactive Analysis （GEPIA） database. The mRNA expression levels of NUF2， magnesium homeostasis-related indicators， such as magnesium transporter 1 （MAGT1）， non-imprinted in Prader-Willi/Angelman syndrome 1 （NIPA1）， NIPA-like domain containing 1 （NIPAL1）， as well as apoptosis-related indicators B cell lymphoma-2 （Bcl-2） and Bcl-2-associated X protein （Bax） in OVCAR3 cells， were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of NUF2， MAGT1， NIPA1， NIPAL1， Bcl-2， and Bax in OVCAR3 cells were quantitatively analyzed by ProteinSimple WES. A model of overexpression of NUF2 was constructed， and Gyp-L intervention was performed. The molecular mechanism by which Gyp-L induces ovarian cancer cell apoptosis by regulating NUF2 and influencing magnesium homeostasis was quantitatively analyzed and detected through cell cloning， TUNEL staining， Real-time PCR， and ProteinSimple WES. Finally， the Mg2+ content and protein synthesis efficiency were detected by immunofluorescence.ResultsGyp-L significantly inhibited the migration and proliferation capabilities of OVCAR3 cells and promoted their apoptosis （P<0.05）. Overexpression of NUF2 markedly increased the expression levels of MAGT1， NIPA1， NIPAL1， and Bcl-2， while reducing the expression level of Bax （P<0.05）. It also significantly elevated intracellular Mg2+ content and protein synthesis efficiency and simultaneously inhibited apoptosis （P<0.05）. Gyp-L could reverse the magnesium homeostasis imbalance and apoptosis inhibition caused by the overexpression of NUF2， downregulating the expression levels of NUF2， MAGT1， NIPA1， NIPAL1， and Bcl-2 （P<0.05）， while upregulating the expression level of Bax （P<0.05）.ConclusionGyp-L can inhibit the occurrence of ovarian cancer， and its mechanism may involve inhibiting the expression of NUF2 to maintain magnesium homeostasis and inducing apoptosis of ovarian cancer cells.关键词：gypenoside L;ovarian cancer;NDC80 kinetochore complex component （NUF2）;magnesium homeostasis;apoptosis20|8|0更新时间：2026-05-29
- 摘要：ObjectiveTo explore the efficacy and mechanism of Euphorbia humifusa on acute kidney injury （AKI） based on network pharmacology， molecular docking and experimental verification.MethodsThe active components and targets of E. humifusa were retrieved from TCMSP and SwissTargetPrediction database， and the AKI targets were screened by GeneCards and Online Mendelian Inheritance in Man（OMIM） databases. The drug targets and disease targets were intersected to construct a protein-protein interaction network， and the intersection targets were subjected to gene ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis. Discover Studio software was used to verify the molecular docking of key components and core targets. Gentamicin （GM） was used to induce AKI rat model. Control group， model group， verapamil （16 mg·kg-1） group， E. humifusa extract （18， 54， 162 mg·kg-1·d-1） group and E. humifusa 70% ethanol extract （423 mg·kg-1） group were continuously administered for 14 days. Urine volume was detected 24 h after modeling and administration. Serum creatinine （SCr）， Blood urea nitrogen （BUN）， 24-hour urine protein （24 hUTP） and uric acid （UA） content； the contents of malondialdehyde （MDA）， glutathione （GSH）， superoxide dismutase （SOD）， carbon monoxide synthase （NOS） and lactate dehydrogenase （LDH） in kidney were measured. The levels of interleukin （IL）-6 and tumor necrosis factor （TNF）-α in serum were detected by enzyme linked immunosorbent assay（ELISA） kit. The pathological changes of renal tissue were detected by hematoxylin-eosin （HE） and Masson staining. Western blot was used to detect the expression of PI3K/protein kinase B（Akt）/NF-κB signaling pathway-related proteins.ResultsIn this study， 13 active components such as kaempferol， luteolin， apigenin， gallic acid and quercetin were screened and identified from E. humifusa. Through bioinformatics analysis， these components and AKI have a total of 289 targets， of which 62 are core targets， including Akt1， TNF， tumor protein p53（TP53） and IL-1β. These targets are mainly involved in the regulation of biological processes such as NF-κB signaling pathway， HIF-1 signaling pathway， TNF signaling pathway， PI3K/Akt signaling pathway and mitogen-activated protein kinase（MAPK） signaling pathway. In animal experiments， we successfully constructed a GM-induced AKI model in rats. Compared with the model group， E. humifusa extract could significantly reduce the levels of 24 hUTP， BUN and SCr in rats （P<0.01）， indicating its improvement effect on renal function. In addition， the extract of E. humifusa also significantly reduced LDH activity and MDA content in rat kidney tissue （P<0.05， P<0.01）， and significantly increased SOD， NOS activity and GSH content （P<0.05）， indicating that the extract of E. humifusa has the potential of anti-oxidation and protection of renal function. Further analysis of inflammatory factors showed that the levels of IL-6 and TNF-α in serum of rats treated with E. humifusa extract were significantly decreased （P<0.01）， indicating that E. humifusa extract had anti-inflammatory effects. In addition， the extract of E. humifusa can also regulate the protein expression of PI3K/Akt/NF-κB signaling pathway， which further confirmed its mechanism of reducing GM-induced AKI.ConclusionThe extract of E. humifusa has a significant therapeutic effect on acute kidney injury through its multi-component and multi-target mechanism. Its effect is reflected in improving renal function， anti-oxidation， anti-inflammation and regulating immune response. These findings provide a scientific basis for the application of E. humifusa in the treatment of acute kidney injury， and point out the direction for future drug development and clinical research.关键词：Euphorbia humifusa;gentamicin;acute kidney injury;oxidative stress18|7|0更新时间：2026-05-29
- 摘要：ObjectiveThis paper aims to systematically reveal the effect difference and mechanisms of Zishenwan against chronic prostatitis （CP） before and after salt-processing of Anemarrhenae rhizoma and Phellodendri chinensis cortex based on an integrated strategy of ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry （UPLC-Q-Orbitrap-MS/MS）， network pharmacology， and serum metabolomics.MethodsZishenwan samples before and after salt-processing of Anemarrhenae rhizoma and Phellodendri chinensis cortex were extracted by alcohol-water dual extraction. The chemical components of each sample were detected by UPLC-Q-Orbitrap-MS/MS， and differential components were screened by multivariate statistical analysis. Network pharmacology analysis was performed based on the identified chemical components of Zishenwan to construct a protein-protein interaction （PPI） network of "component， target， and pathway"， and the core components， targets， and pathways of Zishenwan against CP were screened. Forty-two male Sprague-Dawley （SD） rats were randomly divided into a blank group， a model group， a Qianliekang group （1.54 g·kg-1）， low- and high-dose raw Zishenwan groups （1.8， 5.4 g·kg-1）， and low- and high-dose salt-processed Zishenwan groups （1.8， 5.4 g·kg-1）. The CP rat model was established by intraprostatic injection of carrageenan. After one week of recovery， the rats were administered the corresponding drugs for 21 days， while those in the blank group and model group received the same volume of normal saline. After the experiment， serum and tissue samples were collected to evaluate pharmacodynamic indicators including organ indices， histopathology， and inflammatory factors in serum. Subsequently， untargeted serum metabolomics technology was used to analyze metabolite changes and perform pathway enrichment analysis. The network pharmacology was used to construct a network of "differential metabolite， reaction， enzyme， and gene".ResultsA total of 76 components were identified in raw and salt-processed Zishenwan， and 34 differential components were screened by multivariate statistical analysis. Among them， the contents of 14 components， including berberine， berberrubine， and phellodendrine， increased after salt-processing， while the contents of 20 components， such as neomangiferin， decreased. The 28 active components and 185 potential targets were screened out by network pharmacology. The core components included berberine， phellodendrine， magnoflorine， and jatrorrhizine， and the core targets included signal transducer and activator of transcription 3 （STAT3）， protein kinase B1 （Akt1）， and transcription factor AP-1 （JUN）. These targets were significantly enriched in pro-inflammatory signaling pathways such as phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） and mitogen-activated protein kinase （MAPK）. Compared with the model group， all Zishenwan administration groups showed decreased prostate index， reduced levels of interleukin （IL）-1β， IL-18， and B-cell lymphoma-2 （Bcl-2） in serum （P<0.05， P<0.01）， as well as varying degrees of alleviation in histopathological damage. At the same dose， compared with the raw Zishenwan groups， the salt-processed Zishenwan groups showed lower prostate index， pathological scores， and IL-1β， IL-18， and Bcl-2 levels in serum， but the differences were not statistically significant. Metabolomics reveals that 38 differential metabolites were reversed after salt-processed Zishenwan administration. Both raw and salt-processed Zishenwan regulated pathways such as β-alanine metabolism and tryptophan metabolism. In addition to the common regulated pathways， the salt-processed group specifically regulated pantothenate and coenzyme A biosynthesis， pyrimidine metabolism， and arginine and proline metabolism. The intersecting pathways between network pharmacology and metabolomics were tryptophan metabolism and arginine and proline metabolism， with overlapping targets including monoamine oxidase A （MAOA） and arginase 1 （ARG1）.ConclusionThe increased contents of components such as berberine and phellodendrine in salt-processed Zishenwan may enhance its therapeutic effect on CP by inhibiting the PI3K/Akt and MAPK signaling pathways， along with multi-target regulation of tryptophan， arginine， and pantothenate metabolism pathways to comprehensively regulate inflammatory and immune responses.关键词：Zishenwan;salt‑processing;chronic prostatitis;ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry （UPLC-Q-Orbitrap-MS/MS）;network pharmacology;metabolomics33|13|0更新时间：2026-05-29
- 摘要：ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication.ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference.ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.关键词：Qingxuan Daozhi formula;child;influenza;randomized controlled study;treatment11|5|0更新时间：2026-05-29
- 摘要：ObjectiveTo observe the clinical efficacy of Anshen Buxin Gao in patients with coronary artery disease （CAD） complicated with somatization disorder after percutaneous coronary intervention （PCI）， as well as its effect on heart rate variability （HRV）.MethodsA total of 96 patients with somatization disorder after PCI were selected and randomized into control and treatment groups （48 cases）. On the basis of standardized Western medical treatment for CAD， the control group received Dailixin， while the treatment group received Dailixin combined with Anshen Buxin Gao. The somatic symptom scale （SSS）， generalized anxiety disorder 7-item scale （GAD-7）， patient health questionnaire-9 （PHQ-9）， and self-rating scale of sleep （SRSS） scores in both groups were recorded before and after treatment. The traditional Chinese medicine symptom efficacy， HRV， and incidence of adverse drug reactions were observed.ResultsA total of 90 patients completed the trial， encompassing 45 patients in the control group and 45 patients in the treatment group. Baseline characteristics between the two groups showed no statistically significant differences， indicating comparability. After treatment， both groups exhibited reductions in SSS， GAD-7， and PHQ-9 scores （P<0.05）， and the treatment group outperformed the control group in alleviating somatic symptoms and anxiety-depression symptoms （P<0.05）. The control group did not achieve a significant reduction in SRSS score， whereas the treatment group effectively lowered the SRSS score （P<0.05）. Regarding traditional Chinese medicine symptom efficacy， the total response rate in the treatment group was 91.1% （41/45）， which was higher than that （71.1%， 32/45） in the control group （Z=-2.663， P<0.05）. Both groups improved HRV in patients with somatization disorder， and the treatment group showed greater improvement （P<0.05）. There were no serious clinical adverse events during the study period. The incidence of adverse reactions in the treatment group was 6.7% （3/45）， which was lower than that （14/45， 31.10%） in the control group （χ2=7.252， P<0.05）.ConclusionThe addition of Anshen Buxin Gao to Dailixin therapy significantly alleviates the clinical symptoms and improves the sleep quality， treatment efficacy， and HRV in patients with CAD complicated with somatization disorder after PCI， while reducing the adverse effects associated with Dailixin alone. This approach demonstrates considerable clinical value and warrants further promotion.关键词：Anshen Buxin Gao;after percutaneous coronary intervention （PCI）;somatization disorder;anxiety-depression;heart rate variability23|51|0更新时间：2026-05-29
- 摘要：ObjectiveTo observe the clinical efficacy and safety of Huatan Quyu formula in treating cerebral small vessel disease （CSVD） with phlegm and blood stasis blocking collateral pattern via randomized controlled trial， and explore its mechanism of improving CSVD by regulating glymphatic system （GS） circulation.MethodsSixty-eight CSVD patients with phlegm and blood stasis blocking collateral pattern in the Department of Encephalopathy， Affiliated Hospital of Shaanxi University of Chinese Medicine from April to December 2024 were selected and randomly divided into an experimental group （34 cases） and a control group， with 34 cases in each group.

Then， safety indicators were monitored， and SPSS 25.0 was used for statistical analysis.ResultsSixty-four patients completed the study （32 in each group）. ①Baseline data： No statistically significant difference was found between the two group. ②Efficacy indicators： After treatment， the experimental group exhibited significantly improved total POMA， SCOPA-AUT， and TCM syndrome scores （P<0.01）， outperforming the control group （P<0.05）. No significant change was observed in MoCA scores between the two groups. ③Imaging indicators： The experimental group showed a reduced PVS area alongside significantly increased CSF flow parameters （including downward flow during the systolic period， and upward flow during the diastolic period） （P<0.01）， which were superior to the control group （P<0.01）. ④Safety： The laboratory indicators were normal in both groups， with no drug-related adverse reactions.ConclusionFor CSVD patients with phlegm and blood stasis blocking collateral pattern， Huatan Quyu formula can safely and effectively improve motor function， autonomic nerve function， and TCM syndromes， with potential mechanisms related to pulsatile CSF flow enhancement and GS circulation efficiency improvement.关键词：Huatan Quyu formula;cerebral small vessel disease;glymphatic system;Cerebrospinal fluid;phlegm and blood stasis blocking collateral syndrome12|5|0更新时间：2026-05-29
- 摘要：By consulting herbal texts， medical records， formula collections， and other relevant literature from various historical periods， as well as modern and contemporary research materials， different aspects of the historical evolution of Zijingpi， including its name， origin， scientific name verification， medicinal part， genuine producing areas， harvesting， processing， and preparation， properties and flavors， and primary indications， were systematically reviewed and verified， providing a basis for the development of famous classical formula preparations containing this medicinal material. According to the textual research， Cercis chinensis was first recorded under the name "Zijingmu" in the Rihuazi Bencao from the Five Dynasties period. From the Song Dynasty to the Qing Dynasty， it was known by various names such as "Zijing"， "Zijingpi"， and "Zijingmupi". In modern and contemporary times， it has been officially named "Zijingpi"， with aliases such as "Mantiaohong"， "Zihuashu"， and "Qingminghua". Historically， the mainstream source of Zijingpi was the dried bark of Cercis chinensis Bunge， a species of the legume family. However， there were also instances of confusion with the Lythraceae plant Lagerstroemia indica L. The producing areas of Zijingpi have no special geographical limitation， and the plant is currently distributed throughout most parts of China. There were no special requirements for harvesting time in ancient times， while modern records indicate harvesting time in spring， summer， and autumn. Ancient processing methods were rarely recorded， with only mentions of stir-frying Zijingpi. Modern practice mostly uses the raw material medicinally. Modern standards prefer it to be "dry， long strips， and thick". The functions of Zijingpi， mainly to promote blood circulation， relieve strangury， and detoxify， have remained consistent from ancient to modern times. Based on the textual research findings， it is recommended that when developing and exploiting the famous classical formulas containing Zijingpi， the bark of C. chinensis should be selected as the source. The processing method should be chosen according to the formula requirements， and if no specific requirements are indicated， it is suggested to use the raw material medicinally.关键词：Zijingpi;origin;scientific name verification;medicinal part;authentic producing area;harvesting;processing;herbal textual research26|10|0更新时间：2026-05-29

"Olfactory Administration of Chinese Medicine"——A New Form of Application of Chinese Medicine 增强出版 AI导读
摘要：As an innovative form of combining traditional aromatherapy with modern nasal medicine delivery technology， "olfactory administration of Chinese medicine" carries the theoretical essence of traditional Chinese medicine （TCM）， which is "moving and channeling Qi and fragrance， dredging and awakening the mind". Based on the systematic records of olfactory therapies in ancient books in emergency care， disorders of consciousness， lung system， and gynecological diseases， this paper examines the historical evolution of its clinical application， and elucidates the profound historical basis and theoretical feasibility of "olfactory administration of Chinese medicine" as a new form. Combined with the innovation and precise application of modern Chinese medicine olfactory agents in multi-system diseases such as nervous， respiratory， and cardiovascular diseases， this paper further analyzes the multi-dimensional mechanism of olfactory receptor pathway， olfactory brain pathway， nasal mucosal blood vessels， and lymphatic channels， and demonstrates its advantages of rapid onset， targeted brain entry， and systemic regulation. Under the background of continuous growth in the demand for external TCM treatment， continuous breakthroughs in the technology of nasal dosage forms， and increasingly accurate drug delivery paths， Chinese medicine olfactory agents have shown significant practical applicability and development potential. This study aims to provide theoretical support and practical direction for the system construction of this form.关键词：olfactory administration of Chinese medicine;aromatic external treatment;multi-pathway mechanism;targeted and efficient delivery39|35|0更新时间：2026-05-29 - 摘要：The disease-syndrome combination model of spleen deficiency with dampness pattern in ulcerative colitis（SDDP-UC） is an important experimental carrier for traditional Chinese medicine （TCM） research on the prevention and treatment of ulcerative colitis （UC）， and the quality of model construction and evaluation directly influences the scientific rigor and translational value of related research conclusions. However， this field still lacks methodological synthesis and a standardized consensus. Based on a comprehensive review of existing literature， this paper summarized isomorphic cues between the spleen deficiency with dampness pattern and UC across four dimensions， including energy metabolism， immune homeostasis， mucosal barrier， and intestinal microecology. The cues were mainly involved in impaired mitochondrial energy supply and glucose metabolic reprogramming， a lowered pro-inflammatory threshold of innate immunity with insufficient adaptive immune regulation， disruption of epithelial barrier gating accompanied by compromised repair capacity， and attenuation of the luminal hypoxia barrier with accumulation of toxic metabolites. A mutually reinforcing process between local "form damage" and systemic "Qi depletion" was further interpreted from a holistic perspective. Regarding modeling strategies， existing studies predominantly use rats as the carrier， apply combined interventions such as improper diet， external damp exposure， and fatigue-related dysregulation to establish the spleen deficiency with dampness pattern background， and subsequently superimpose chemical stimulation to induce UC-like colonic damage， with a total modeling period generally spanning three to four weeks. In terms of the evaluation system， a multidimensional framework integrating syndrome assessment， histopathology， mechanistic indices， and pharmacodynamic counter-verification was outlined. On this basis， current methodological bottlenecks of models were systematically identified， including syndrome drift risk and compounded stress dilemma in temporal sequencing， syndrome confounding from etiological simulation， cross-sectional evaluation bias related to modeling duration， inadequate disease-syndrome linkage and control design within the evaluation system， and limited controls with overly single-track decision logic in formula-based syndrome verification. To address the above issues， a construction and evaluation strategy emphasizing streamlining of core etiological factors， multi-node dynamic monitoring， integration of core disease-syndrome indicator clusters， and establishment of a formula-based syndrome verification system was proposed， providing a reference for the standardized construction and scientific evaluation of the SDDP-UC model.关键词：ulcerative colitis;spleen deficiency with dampness pattern;disease-syndrome combination model;energy metabolism;immune homeostasis;mucosal barrier;intestinal microecology22|8|0更新时间：2026-05-29
- 摘要：ObjectiveThis paper aims to systematically summarize the construction methods and characteristics of Alzheimer's disease （AD） animal models， providing a reference for improving AD animal models.MethodsLiterature related to AD animal models published between January 2022 and April 2025 was retrieved from China National Knowledge Infrastructure （CNKI）， China Biomedical Literature Database （CBM）， Wanfang Data， and VIP Database. Information such as experimental animal species， month of age， sex， modeling methods， and period， as well as evaluation indicators， was collated， extracted， and imported into Microsoft Excel 2024 to establish the database. In addition， various modeling methods and detection means were summarized and compared.ResultsA total of 400 articles were included. Among the AD animal models， amyloid precursor protein/presenilin-1 （APP/PS1） mice were used most frequently， with a predominance of male animals. Typically， 3-4-month-old rats or 5-6-month-old mice were selected. The main modeling methods included natural aging， accelerated aging， surgical intervention， drug induction， and transgenic technology. The modeling period was mainly concentrated in a single day or 6-8 weeks. Detection indicators of the models focused on physiological， behavioral， pathological-morphological， and biochemical phenotypes.ConclusionThe construction methods of AD animal models are relatively mature， with multifactorial interventions effectively simulating human pathology， though certain limitations remain. By systematically reviewing and analyzing recent experimental literature of AD animal models， this study aims to provide theoretical support and a reference for further improving the construction of the AD animal model.关键词：Alzheimer's disease;animal model;data mining;application analysis;traditional Chinese medicine syndrome12|7|0更新时间：2026-05-29
- 摘要：From the theoretical perspective of "body fluids and blood stasis mixing"， environmental microplastics （MPs） are conceptualized as a "novel turbid-toxin". This study aims to elucidate the complete pathogenic pathway through which MPs act as a key driving force （the "crucible" of pathogenesis） in the initiation and progression of atherosclerosis （AS）. By tracing the classical theories in the Chapter The Occurrence of All Diseases of Miraculous Pivot （Ling Shu）， this paper clarifies the core connotations of "body fluids"-it not only refers to endogenous pathological fluids and lipid turbidity but also provides a theoretical basis for incorporating "exogenous turbid fluids"， thereby laying a logical foundation for conceptualizing MPs as a "novel turbid-toxin". Meanwhile， the implications of "blood" （encompassing both blood quality abnormalities and blood stasis） and the dynamic process of "mixing" are elucidated. Drawing upon modern toxicological evidence， this paper demonstrates the high homology between MPs and "exogenous turbid-fluids" from three aspects： Morphology， toxicity， and invasion routes. The micro/nano-scale particle morphology of MPs enables mobility within the bloodstream. The multiple exposure pathways of MPs correspond to the traditional Chinese medicine understanding of pathogens invading through the mouth， nose， and skin. The characteristics of accumulating in vivo while inducing oxidative stress and inflammatory responses of MPs fully embody the pathogenic features-adhesion， binding， and vessel damage-of "turbid-toxin". On this basis， the dynamic pathogenesis of MP-induced AS is systematically interpreted. Initially， MPs with the "turbid-toxin" nature impair nutrient-defense harmony and cause endothelial dysfunction. Subsequently， as the core of "mixing"， they interact with blood lipids and immune cells， generating heat and phlegm to form a major pathological hub of chronic inflammation. Ultimately， this process drives the coalescence of phlegm， stasis， and turbid-toxin into tangible plaques， evolving from stable lesions to vulnerable masses and accumulations. By integrating classical pathogenic model with contemporary environmental medicine， this study establishes an analytical framework that bridges macro-theory and micro-mechanisms for understanding the cardiovascular risks of MPs through an integrative Chinese-Western medicine lens.关键词：microplastics;atherosclerosis;body fluids and blood stasis mixing;integrative Chinese-Western medicine11|5|0更新时间：2026-05-29
- 摘要：Digestive system malignant tumors （DT） are one of the leading causes of death globally and carry a heavy economic burden. Gut microbiota plays a critical role in maintaining host health， including providing nutrition， defending against pathogens， and promoting immune development. In recent years， more and more studies have shown that dysbiosis of gut microbiota is closely associated with DT such as gastric cancer， liver cancer， and colon cancer. Therefore， targeted regulation of gut microbiota plays a potential role in inhibiting the growth and metastasis of DT， while its specific regulatory mechanism remains unclear. As the studies about the anti-tumor effects of traditional Chinese medicine （TCM）， especially the basic and clinical studies on the regulation of gut microbiota by TCM in tumor treatment， have been growing， the therapeutic effects of TCM on DT have attracted much attention. This paper provides a systematic review of the relationship between gut microbiota and DT， as well as the related studies on the modulation of gut microbiota by TCM against DT， with the aim of providing a foundation and direction for future basic and clinical studies on DT. The literature review shows that gut microbiota influence the occurrence and development of DT through multiple pathways. These pathways include triggering chronic inflammation， producing oncogenic metabolites， inducing genomic instability， regulating the immune system， and altering the tumor microenvironment. TCM can exert anti-DT effects by regulating the composition of gut microbiota， modulating gut microbiota metabolites， repairing intestinal barrier function， and influencing immune functions. Therefore， understanding the relationship between gut microbiota and DT and the regulatory mechanisms of TCM may provide new strategies for future prevention and treatment of DT.关键词：gut microbiota;digestive system malignant tumors;traditional Chinese medicine;immunity;metabolite regulation72|45|0更新时间：2026-05-29
- 摘要：Gastric ulcer （GU） is a high-incidence digestive system disease characterized pathologically by disruption of gastric mucosal integrity， with clinical features including a prolonged course and periodic recurrence. Modern medicine attributes its pathogenesis to the dynamic imbalance between aggressive and defensive factors，while traditional Chinese medicine （TCM） posits its development as closely linked to spleen deficiency. Current therapies combining acid suppressants and antibiotics face challenges such as high recurrence rates，poor mucosal healing，and adverse drug reactions. Long-term use may induce metabolic disturbances like hypergastrinemia and reduced intestinal microbiota diversity. Therefore，exploring safer and longer-lasting therapeutic strategies has become a critical focus. TCM has extensive clinical experience and unique advantages in GU prevention and treatment. Studies demonstrate that the classic formula Shenling Baizhu San exhibits therapeutic properties of "invigorating spleen and tonifying Qi to restore physiological balance and eliminating dampness and regulating middle energizer to unblock Qi movement"， enabling a holistic approach targeting both symptoms and root causes in GU with spleen deficiency as the core pathology by suppressing aggressive factors and strengthening defensive factors. Experimental research reveals its mechanisms involve enhancing the physicochemical barrier of the mucus layer，repairing epithelial barriers and microcirculation，modulating gastric acid secretion and gastrointestinal motility，and regulating microecological barriers and mucosal immunity. Clinical evidence confirms its synergistic effects in promoting ulcer healing，improving Helicobacter pylori eradication rates，and reducing recurrence risks. This review examined the etiology and pathogenesis of GU and systematically evaluated Shenling Baizhu San from three perspectives-clinical application，pharmacological effects， and experimental research-to provide insights for optimizing integrated traditional Chinese and Western medicine protocols and expanding its clinical applications.关键词：gastric ulcer;Shenling Baizhu San;clinical application;pharmacological action;experimental research13|7|0更新时间：2026-05-29
- 摘要：Asthma and cough variant asthma （CVA） are both chronic heterogeneous diseases characterized by airway microenvironment homeostasis disruption as their core pathological basis. In recent years， micro ribonucleic acid （miRNA）， as core post-transcriptional regulators， have been shown to finely modulate multiple critical signaling pathways， including Janus kinase/signal transducer and activator of transcription （JAK/STAT）， nuclear factor-κB （NF-κB）， transforming growth factor-β/Smad （TGF-β/Smad）， and phosphoinositide 3-kinase/protein kinase B （PI3K/Akt）， as well as various pathological processes such as airway epithelial barrier restoration， type 1 helper T cell（Th1）/Th2 immune balance， M1/M2 macrophage polarization， airway smooth muscle cell function， and airway hyperresponsiveness. miRNAs play a pivotal role in maintaining and disrupting airway microenvironment homeostasis. Based on recent Chinese and international literature， a logical framework centered on "airway microenvironment homeostasis disruption， miRNA regulation， and microenvironment restoration" was constructed. From the perspective of the airway microenvironment， the therapeutic roles of miRNA in asthma and CVA were systematically summarized， and the cascade regulatory mechanisms of miRNA throughout the entire disease course were elucidated. The hub miRNA was identified， and research progress on traditional Chinese medicine intervention strategies was explored. Furthermore， current clinical studies on RNA therapeutics and traditional Chinese medicine in achieving multi-target and multi-pathway integrated treatment by modulating miRNA were analyzed. The value of miRNA as biomarkers for diagnosis， phenotyping， and prognosis assessment， as well as the potential and application prospects of miRNA mimics and antagonists in precision therapy， were summarized， with the ultimate goal of advancing precision therapy for asthma and CVA.关键词：airway microenvironment;asthma;cough variant asthma（CVA）;micro ribonucleic acid（miRNA）;signaling pathway;traditional Chinese medicine24|8|0更新时间：2026-05-29
- 摘要：Breast cancer prevention and treatment have become major issues that urgently need to be addressed in the field of global public health. As a key pathological transitional stage in the progression of breast cancer， preneoplastic breast cancer （PBC） carries a significant risk of clinical transformation. Effective intervention in the progression of PBC is of great clinical significance in preventing the occurrence of breast cancer. Pathological studies have shown that abnormal angiogenesis is a key mechanism driving the transformation of PBC into breast cancer. Vascular endothelial growth factor （VEGF）， as a core regulatory molecule that promotes angiogenesis， plays a pivotal role in this process. The malignant transformation of PBC is closely associated with the abnormal activation of the VEGF-mediated pro-angiogenic network. Although modern medicine has achieved certain therapeutic effects through surgery and endocrine therapy， clinical limitations such as invasiveness， drug resistance， and adverse reactions still exist. Recent studies have demonstrated that the VEGF signaling system mediates the phosphatidylinositol 3-kinase-protein kinase B （PI3K/Akt） signaling pathway and the mitogen-activated protein kinase （MAPK） pathway. In addition， the hypoxia-inducible factor-1α （HIF-1α）/VEGF signaling pathway and the delta-like ligand 4 （DLL4）/Notch receptor 1 （Notch1） signaling pathway， together with other pathways， form a complex regulatory network that plays a central role in angiogenesis during PBC. Traditional Chinese medicine （TCM）， characterized by multi-component synergy， multi-pathway regulation， and high safety， demonstrates significant advantages in inhibiting pathological angiogenesis and blocking PBC progression by targeting the VEGF signaling pathway. From the perspective of VEGF pathway regulation， this paper systematically reviews the latest research progress on TCM in inhibiting angiogenesis and intervening in PBC， and discusses its mechanisms and application value in the early prevention and treatment of PBC， with the aim of providing references for optimizing clinical intervention strategies for PBC.关键词：traditional Chinese medicine;preneoplastic breast cancer;vascular endothelial growth factor（VEGF）;angiogenesis;research advances91|31|0更新时间：2026-05-29
- 摘要：The disease-syndrome combination animal model in traditional Chinese medicine （TCM） andrology serves as an important bridge linking TCM theory with modern medical research， providing a key experimental platform for elucidating the 'syndrome-disease' correlation mechanism in male-specific diseases and for screening effective prescriptions. This article reviews recent progress in animal model research on common TCM andrological diseases， including prostatic diseases， sexual dysfunction， and male infertility， with a focus on analyzing the application， advantages， and disadvantages of various modeling strategies， such as immune induction， hormonal intervention， and multi-factor combination across different syndrome types. However， despite breakthroughs in model construction techniques， current research still faces several challenges， including insufficient standardization of syndrome differentiation and difficulties in quantifying TCM-specific indicators. Future studies need to optimize model evaluation systems by integrating modern technologies， in order to promote the standardization and internationalization of TCM andrology research.关键词：andrology of traditional Chinese medicine;disease-syndrome combination;animal model;evaluation system17|7|0更新时间：2026-05-29
- 摘要：Yinqiao San （YQS） is a classic prescription in Systematic Differentiation of Warm Diseases， which has the effects of pungent dispersing， bitter descending， clearing heat， and removing toxin. It is a classic prescription for the treatment of the onset of warm disease. The prescription contains ten kinds of traditional Chinese medicines， which are in proper compatibility. The ancient and modern physicians often modify the prescription for the treatment of various diseases in children， which has a significant effect. At present， with the rapid development of modern technology， the research on the mechanism of YQS at the molecular level is constantly deepening and improving， which provides new ideas and scientific basis for the treatment of pediatric diseases by YQS. Therefore， this paper summarized and collated the relevant research literature on YQS published by scholars from China and other countries in recent years from six aspects： the textual research on the source of YQS prescription， the theory of formulation， clinical application， active ingredients of traditional Chinese medicine， pharmacological effects， and decocting and administration methods. It expounded on the diseases treated by YQS which were recorded in modern literature， involving the respiratory system， nervous system， rheumatic， immune， and renal disease systems， skin system， infectious system， and its application in diseases such as mucocutaneous lymph node syndrome， viral myocarditis， mesenteric lymphadenitis， and post-nasal drip syndrome. At the same time， it elucidated the mechanism of YQS in the treatment of diseases and its correlation with antiviral， antibacterial， antipyretic， and analgesic effects， improvement of microbiota， regulation of immune function， anti-inflammatory effect， and improvement of pulmonary damage. The decoction time of YQS had a significant effect on its clinical effect， and the best decoction time for its efficacy was 3 to 6 minutes after boiling.关键词：Yinqiao San;classic prescription;active ingredients of traditional Chinese medicine;pharmacological effects;clinical application;decocting method20|5|0更新时间：2026-05-29

- 摘要：The blood-brain barrier （BBB） is a physical and biochemical barrier that precisely regulates brain homeostasis and plays a central role in controlling the transport of endogenous and exogenous drugs and related metabolites across the blood-brain interface. These functions of the BBB are mediated by its major components， including brain microvascular endothelial cells （BMECs）， tight junction protein complexes， and influx and efflux transporter proteins. One of the pathological features of ischemic stroke （IS） is BBB disruption， which plays an important role in the development of post-stroke brain injury and subsequent neurological dysfunction. Therefore， given the increasing incidence of IS， there is an urgent need to develop new therapeutic strategies to prevent BBB dysfunction and thereby protect injured brain tissue after IS. This study describes the pathological mechanisms by which BMEC injury after IS leads to BBB dysfunction and elucidates the association between BMECs and IS， including the regulation of apoptosis， autophagy， inflammatory responses， oxidative stress， neurotoxic effects， and cerebral edema.
