- “最新研究发现，酸枣仁汤通过改善神经炎症和突触可塑性，有效抗抑郁。”摘要：ObjectiveTo evaluate the effect of Suanzaoren Tang on the rat model of depression established by solitary culture combined with chronic unpredictable mild stress by reshaping the inflammatory microenvironment and mediating changes in hippocampal synaptic plasticity.MethodsSeventy-two male SD rats were randomized by a random number table into six groups： control group， model group， fluoxetine group （0.003 6 g·kg-1）， and high-（10 g·kg-1）， medium-（5 g·kg-1）， low-dose （2.5 g·kg-1）Suanzaoren Tang groups， with 12 rats per group. The sucrose preference rate and open field test scores of rats in each group were observed. Western blot was employed to determine the expression levels of the key proteins in the specificity protein 1 （SP1）/sphingosine kinase 1 （SK1）/sphingosine-1-phosphate receptor 1 （S1PR1） signaling pathway， as well as hippocampal proteins synaptophysin Ⅰ （SYNⅠ）， postsynaptic density protein-95 （PSD-95）， and family with sequence similarity 19， member A5 （FAM19A5）. Immunohistochemistry was employed to detect the positive expression of SP1， PSD-95， SYNⅠ， interleukin （IL）-10， and IL-6. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of SP1 and S1PR1. Finally， transmission electron microscopy was employed to observe the ultrastructural changes of hippocampal synapses.ResultsCompared with the control group， the model group exhibited a decrease in sucrose preference index （P<0.01） and reduced total scores for horizontal and vertical movements in the open field test （P<0.01）， which indicated the successful modeling of depression. Moreover， the model group showed reduced synaptic vesicles in the hippocampus （P<0.01）， up-regulated expression of SP1， SK1， S1PR1， and IL-6 （P<0.01）， and down-regulated expression of SYNⅠ， PSD-95， FAM19A5， and IL-10 （P<0.01）. Compared with the model group， high- and medium-dose Suanzaoren Tang and fluoxetine increased the sucrose preference index and the total scores for horizontal and vertical movements in the open field test （P<0.01）. All Suanzaoren Tang groups and the fluoxetine group demonstrated reductions in SP1， SK1， S1PR1， and IL-6 expression （P<0.05， P<0.01）， alongside restored synaptic vesicles in the hippocampus （P<0.05， P<0.01）.ConclusionSuanzaoren Tang modulates hippocampal expression of FAM19A5， SYNⅠ， PSD-95， IL-10， IL-6， and the SP1/SK1/S1PR1 pathway in the rat model of depression. The antidepressant effects may be related to the ability of reducing neuroinflammation and enhancing synaptic plasticity.关键词：family with sequence similarity 19， member A5 （FAM19A5）;depression;specificity protein 1 （SP1）/sphingosine kinase 1 （SK1）/sphingosine-1-phosphate receptor 1 （S1PR1） signaling pathway;synaptic plasticity;neuroinflammation239|120|0更新时间：2025-10-09
- “最新研究发现，五味参芩汤通过调控“肺-肠轴”改善肺纤维化，为治疗肺纤维化提供新方案。”摘要：ObjectiveTo explore the mechanism of action of Wuwei Shenqintang in improving pulmonary fibrosis by using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF-MS） for metabolomic analysis of lung tissue and feces.MethodsA rat model with pulmonary fibrosis was established by intratracheal injection of 5 mg·kg-1 bleomycin. The successfully modeled rats were randomly divided into a blank group， a model group， a prednisone （3.15 mg·kg-1） group， and low-dose， medium-dose， and high-dose groups of Wuwei Shenqintang （4.586， 9.172， 18.344 g·kg-1）. The rats were given intragastric administration once a day for 28 consecutive days. Hematoxylin-eosin （HE） staining was used to measure the pathological changes in lung and colon tissue， and Masson staining was used to detect the degree of pulmonary fibrosis. Enzyme-linked immunosorbent assay （ELISA） was used to detect the expression of interleukin-1β （IL-1β）， IL-6， IL-8， tumor necrosis factor-α （TNF-α）， and secretory immunoglobulin A （SIgA） in bronchoalveolar lavage fluid and intestinal mucus. Immunohistochemistry and reverse transcription quantitative polymerase chain reaction （Real-time PCR） were used to detect the expression of type Ⅰ collagen （Col-Ⅰ）， fibronectin （FN）， and alpha smooth muscle actin （α-SMA） in lung tissue. UPLC-Q-TOF-MS was used to study the changes in the metabolic network of lung tissue and feces in rats with pulmonary fibrosis treated with Wuwei Shenqintang， screen potential biomarkers for the treatment of pulmonary fibrosis by Wuwei Shenqintang， and perform pathway enrichment analysis.ResultsCompared with the blank group， the model group showed extensive inflammatory cell infiltration and continuous fibrotic lesions in lung tissue， colonic mucosal damage， and connective tissue hyperplasia. The expression of IL-6， IL-8， IL-1β， TNF-α， and SIgA in bronchoalveolar lavage fluid and intestinal mucus was significantly increased （P<0.01）. The expression of Col-Ⅰ， FN， and α-SMA proteins and mRNAs in lung tissue was significantly upregulated （P<0.01）. Compared with the model group， the groups of Wuwei Shenqintang exhibited significantly reduced inflammatory infiltration and blue collagen deposition in lung tissue， alleviated colonic damage， decreased expression of IL-6， IL-8， IL-1β， TNF-α， and SIgA in bronchoalveolar lavage fluid and intestinal mucus （P<0.01）， and reduced average absorbance values and mRNA expression of Col-Ⅰ， FN， and α-SMA in lung tissue （P<0.05， P<0.01）， with the prednisone group and the medium-dose and high-dose groups of Wuwei Shenqintang showing the most significant effects. The metabolomics results for lung tissue showed that compared with the blank group， the model group had 19 significantly different compounds （P<0.05， P<0.01）. Wuwei Shenqintang could normalize 17 of these compounds compared with the model group （P<0.05， P<0.01）. Fecal metabolomics results showed that compared with those in the blank group， there were 42 compounds with significant differences in the model group （P<0.05， P<0.01）. Compared with the model control group， Wuwei Shenqintang could normalize 41 of these compounds （P<0.05， P<0.01）. The combined analysis results indicated that Wuwei Shenqintang might inhibit pulmonary fibrosis by regulating the biosynthesis of phenylalanine， tyrosine， and tryptophan as well as the retinol metabolism pathway.ConclusionWuwei Shenqintang can ameliorate pulmonary fibrosis， which may be related to the regulation of the "lung-intestine axis".关键词：Wuwei Shenqintang;pulmonary fibrosis;lung-intestine axis;pharmacodynamics;metabolomics125|73|0更新时间：2025-10-09

- “最新研究发现，马鞭草苷能显著提高人冠状病毒HCoV-229E感染巨噬细胞的存活率，可能通过激活线粒体自噬、维持线粒体膜电位稳定发挥作用。”摘要：ObjectiveTo investigate the protective effect and mechanism of verbenalin on mouse mononuclear macrophage leukemia cells （RAW264.7） damaged by human coronavirus （HCoV）-229E infection， thereby providing experimental evidence for its development and application.MethodsRAW264.7 macrophages were infected with different concentrations of HCoV-229E to establish a coronavirus-induced macrophage injury model using the cell counting kit-8 （CCK-8） assay for assessing cell proliferation and viability. Cells were randomly divided into four groups： normal control， verbenalin group （125 μmol·L-1）， model group （HCoV-229E）， and HCoV-229E + verbenalin group （HCoV-229E + 125 μmol·L-1 verbenalin）. Cell viability was measured using the CCK-8 assay， and the maximum non-toxic concentration （CC0）， half-maximal cytotoxic concentration （CC50）， half-maximal effective concentration （EC50）， and selectivity index （SI） of verbenalin were calculated. Calcein/PI double staining was used to assess cell viability and cytotoxicity， and JC-1 staining was applied to evaluate changes in mitochondrial membrane potential （MMP）. mito-Keima adenovirus labeling was used to assess mitophagy levels in each group.ResultsA macrophage infection model was successfully established by infecting RAW264.7 cells with the original concentration of HCoV-229E for 36 h. The CC0 of verbenalin was 125 μmol·L-1. The CC50 was 448.25 μmol·L-1. The EC50 against HCoV-229E-infected cells was 46.28 μmol·L-1， and the SI was 9.68. Compared with the normal group， the model group showed significantly reduced cell survival rate （P<0.01）， increased cell death rate （P<0.01）， decreased MMP （P<0.01）， and suppressed mitophagy （P<0.01）. In contrast， verbenalin treatment significantly improved cell survival rate （P<0.01）， reduced cell death rate （P<0.01）， alleviated MMP loss （P<0.01）， and enhanced mitophagy levels （P<0.01） compared with the model group.ConclusionVerbenalin can enhance the survival rate of macrophages following HCoV-229E infection. The underlying mechanism may be associated with the activation of mitophagy， maintenance of MMP stability， and alleviation of mitochondrial damage.关键词：verbenalin;human coronavirus （HCoV）-229E;mononuclear macrophage leukemia cell （RAW264.7）;mitophagy;mitochondrial membrane potential98|68|0更新时间：2025-10-09

The skin on the back of the guinea pigs in each group was depilated and then abraded with sandpaper. Except for the normal group， 200 μL of VZV solution was dropped on the damaged parts of the back of the guinea pigs in the other groups， and the infection lasted for 2 consecutive days. The drug administration started 2 hours after the infection on the first day and lasted for 7 days. The pathological changes of the back of the guinea pigs in each group were observed every day starting from the second day after the infection. On the 7th day， the guinea pigs were sacrificed by CO2 anesthesia. The locally infected skin was taken， and the viral DNA nucleic acid load was detected by real-time polymerase chain reaction （Real-time PCR）. The pathological histology examination was carried out after hematoxylin-eosin （HE） staining. Seventy rats were randomly divided into seven groups according to their body weight， namely the normal group， the model group， the positive control group， the high-dose group， medium-dose group， and low-dose group of Jidesheng Sheyao tablets （1.08， 0.54， 0.27 g·d-1）， and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets （0.54 g·d-1 + 1.2 g·kg-1·d-1）. The rats in each group （except the normal group） were subcutaneously inoculated with 50 μL of VZV suspension between the web of the first and second fingers of the left forelimb. The skin on the back of the rats was depilated， and the drug administration started 2 hours after the infection and lasted for 10 days. The mechanical withdrawal threshold of the paws of the rats was detected by a Von Frey filament algometer before inoculation and on the 1st， 3rd， 6th， 8th， and 10th days after inoculation， and the thermal withdrawal reflex latency of the paws of the rats was detected by a hot and cold plate algometer. On the 10th day after the virus inoculation， the rats were anesthetized after the behavioral examination， and the dorsal root ganglia of the spinal cord and spinal cord segments were taken. The contents of substance P （SP）， neurokinin （NK）， tumor necrosis factor-α （TNF-α）， and interleukin-1β （IL-1β） in the dorsal root ganglia of the spinal cord and spinal cord were detected by enzyme-linked immunosorbent assay （ELISA）.ResultsCompared with those in the normal group， the guinea pigs in the model group had obvious skin herpes lesions （P<0.01）. The viral nucleic acid load was high （P<0.01）， and there were disorganized subcutaneous cellular structures and obvious infiltration of inflammatory cells and cell necrosis （P<0.01）. The mechanical withdrawal threshold of the paws and the thermal withdrawal reflex latency of the paws of the rats were significantly decreased （P<0.05）， and the contents of NK， SP， TNF-α， and IL-1β in the dorsal root ganglia of the spinal cord and spinal cord of the rats were significantly increased （P<0.01）. Compared with the model group， the high-dose and medium-dose groups of topical administration of Jidesheng Sheyao tablets and the group of oral administration combined with topical application could significantly improve the lesions such as skin redness and herpes of the guinea pigs caused by VZV infection （P<0.01）， reduce the VZV viral nucleic acid load in the skin tissues of the guinea pigs （P<0.01）， alleviate the degree of inflammatory cell infiltration and skin cell necrosis in the skin tissue （P<0.05）， significantly increase the mechanical withdrawal threshold of the paws and the thermal withdrawal reflex latency of the paws of the rats （P<0.05）， and decrease the contents of NK， SP， TNF-α， and IL-1β in the dorsal root ganglia of the spinal cord and spinal cord of the rats （P<0.01）.ConclusionJidesheng Sheyao tablets demonstrated significant therapeutic effects on VZV-induced skin infections and postherpetic neuralgia （PHN）， providing a promising candidate for the prevention and treatment of VZV infections.关键词：Jidesheng Sheyao tablets;varicella-zoster virus;postherpetic neuralgia;dorsal root ganglion;mechanical withdrawal threshold of paw;thermal withdrawal latency73|66|0更新时间：2025-10-09
- “最新研究发现，基于人源化IGF1R小鼠的RSV感染肺炎动物模型成功构建，为抗RSV药物评价提供新平台。”摘要：ObjectiveTo construct an animal model of respiratory syncytial virus（RSV）-infected pneumonia suitable for preclinical studies.MethodsThe virulence of RSV to the four cell lines was observed by cytopathic effect （CPE）， and 50% tissue culture infective dose（TCID50） was calculated. Twenty BALB/c mice were randomly divided into a normal group and a model group. Six BALB/c-hIGF1R mice served as the humanized IGF1R model group. Except for the normal group， the other groups received intranasal RSV infection on days 1 and 3 to establish a viral pneumonia model. The efficacy of establishing an RSV-induced pneumonia animal model based on humanized insulin-like growth factor 1 receptor （IGF1R） mice was evaluated by measuring organ indices， peripheral blood lymphocyte percentages， pulmonary pathology and imaging， and pulmonary viral load. Additionally， ten BALB/c mice served as normal group， and thirty-two BALB/c-hIGF1R mice were randomly assigned to humanized IGF1R model group， ribavirin group （82.5 mg·kg-¹·d-¹）， and high and low dose groups of Lianhua Qingwen （3.3 mg·kg-¹·d-¹ ， 1.65 mg·kg-¹·d-¹）， with 8 mice per group. The viral load in lung tissue was measured after ribavirin and Lianhua Qingwen intervention， and the model was applied to the evaluation of anti-RSV drugs.ResultsIn the lungs of the humanized IGF1R model group， large solid and diffuse ground-glass shadows were seen， and the lung volume was significantly increased （P<0.01）. The lung index was significantly increased （P<0.01）， and both the spleen index and thymus index were significantly decreased （P<0.01）. The percentages of CD3+ and CD4+T cells were significantly decreased （P<0.05）， and there was a large amount of inflammation and stasis in the perivascular area of the lung tissue， which was predominantly characterized by lymphocytes. The endothelium of blood vessels was partially detached， with a small number of eosinophils. After infecting BALB/c-hIGF1R mice with RSV， the expression of viral nucleic acids in the lung tissue of the mice was significantly increased， with significant differences compared with the normal group （P<0.01）. The expression of viral nucleic acids in the ribavirin group and the high and low dose groups of Lianhua Qingwen was significantly reduced， with significant differences compared with the normal group （P<0.01）.ConclusionHumanized IGF1R mice are more susceptible to respiratory SVC， and the animal model of RSV-infected pneumonia based on humanized IGF1R mice was successfully constructed， which is suitable for the evaluation of anti-RSV drugs.关键词：respiratory syncytial virus;animal model;insulin-like growth factor 1 receptor;pulmonary imaging106|72|0更新时间：2025-10-09
- “最新研究发现，藏药三味豆蔻汤能改善阿尔茨海默病小鼠认知功能，可能通过调控Wnt/β-catenin信号通路促进BDNF表达，恢复突触可塑性和神经元信号传递。”摘要：ObjectiveTo explore the effects of the Tibetan medicine Sanwei Doukoutang （SWDK） on cognitive dysfunction in mice suffering from Alzheimer's disease （AD） and its related mechanism.MethodsFifty SPF 5 × FAD mice were randomly divided into model group， total ginsenoside group（0.04 g·kg-1）， high-， medium-， and low-dose groups of SWDK （32.60， 16.30， 8.15 g·kg-1）， with 10 mice in each group， and ten wild-type mice of the same age were used as the normal group， male and female in 1∶1. Gavage administration was performed once daily for 8 weeks. The Morris water maze test and contextual fear memory experiment were used to observe learning and memory function. Hematoxylin-eosin （HE） staining was utilized to observe the changes in the pathomorphology of brain tissue in mice. The levels of synaptophysin （SYP） and postsynaptic dense substance 95 （PSD95） in mice serum were detected by enzyme-linked immunosorbent assay （ELISA）. The positive expression of brain-derived neurotrophic factor（BDNF） in the dentate gyrus （DG） region of mouse brain tissue was observed by immunohistochemistry （IHC）. The protein levels of BDNF， Wnt family member 3A（Wnt3a）， and β-catenin were detected in the hippocampus of mice by Western blot.ResultsCompared with the normal group of mice， the model group of mice had significantly more complex swimming routes and lower swimming speed （P<0.01）， significantly lower percentage of time spent in the target quadrant （P<0.01）， and a significantly lower percentage of freezing time （P<0.05）. The number of neurons in the hippocampal region of mice was obviously reduced and unevenly arranged. The levels of SYP and PSD95（P<0.01） in the serum of mice were reduced， and the positive expression of BDNF in the DG region of the brain tissue of mice was reduced. The levels of hippocampal BDNF， Wnt3a， and β-catenin proteins in the hippocampus of mice were obviously reduced （P<0.05， P<0.01）. Compared with the model group， the mice in the SWDK group and the total ginsenoside group had significantly shorter swimming routes， the high- and medium- dose SWDK groups significantly higher swimming speeds （P<0.01）， significantly higher percentage of time spent in the target quadrant （P<0.01）， obviously higher percentage of Freezing time （P<0.05）， and obviously more neurons in the hippocampal region of the mice with tighter arrangement. The mice had elevated levels of serum SYP （P<0.05， P<0.01）， PSD95 （P<0.01）， increased BDNF-positive cells in the DG region of brain tissue， and obviously elevated levels of BDNF， Wnt3a， and β-catenin proteins in the hippocampus of mice （P<0.05， P<0.01）.ConclusionSWDK can significantly improve the cognitive dysfunction of AD mice， and its mechanism may be related to regulating the Wnt/β-catenin signaling pathway， which promotes BDNF expression and thereby enhances synaptic plasticity， allowing neuronal signaling to be restored.关键词：Sanwei Doukoutang;Tibetan medicine;brain derived neurotrophic factor（BDNF）;synaptic plasticity;cognitive dysfunction85|62|0更新时间：2025-10-09
- “最新研究系统梳理了呼吸道病毒感染肺炎病证结合动物模型的研究进展，为中医药防治呼吸道传染病提供实验平台，助力理论现代化与新药研发。”摘要：Currently， viral pneumonia （VP） presents a major challenge to global public health. Traditional Chinese medicine （TCM） prevention and treatment of VP is guided by the core concept of strengthening vital energy and eliminating pathogenic factors rather than targeting specific pathogens， alongside a holistic approach of syndrome differentiation and treatment. By summarizing the clinical syndromes of patients， the core pathogenesis was clarified to achieve individualized therapy. Animal models for disease-syndrome combination integrate the etiology and pathogenesis of VP and simulate the individualized manifestations of patients at different disease stages， providing an experimental platform for elucidating the theoretical basis of TCM in treating VP and promoting the development of effective TCM formulations. However， there are limitations in the application and promotion of disease-syndrome combination animal models due to the lack of standardization and normalization of model construction systems， which arise from diverse species selection， compound modeling methods， and multidimensional evaluation indicators. This paper systematically reviewed the recent research on animal models for disease-syndrome combination in VP from the perspective of species selection， modeling methods， evaluation indicators， and application status. Furthermore， it summarized the advantages and limitations of existing models， identifies future directions for improvement， and proposes optimization strategies. This review provides a reference for establishing standardized and normalized animal models for disease-syndrome combinations in VP， supporting the theoretical modernization of TCM in preventing and controlling emerging respiratory infectious diseases， and contributing to the development of new TCM drugs.关键词：viral pneumonia;disease-syndrome combination;animal model;traditional Chinese medicine118|94|0更新时间：2025-10-09
- “最新研究发现，四逆散加减方能有效缓解慢性束缚应激引起的小鼠焦虑行为，其机制涉及神经递质稳态调控和代谢通路调节。”摘要：ObjectiveTo elucidate the potential mechanism of modified Sinisan （MSNS） in alleviating anxiety-like behaviors induced by chronic restraint stress （CRS） in mice at the metabolic level based on serum untargeted metabolomics and identify key metabolites and metabolic pathways regulated by MSNS.MethodsSeventy-two male C57BL/6 mice were randomly assigned into six groups： control， model， high-dose （2.4 g·kg-1） MSNS， medium-dose （1.2 g·kg-1） MSNS， low-dose （0.6 g·kg-1） MSNS， and positive control （fluoxetine， 2.6 mg·kg-1）. Except the control group， the other groups were subjected to CRS for the modeling of anxiety. Mice were administrated with corresponding agents by gavage 2 h before daily restraint for 14 days. Anxiety-like behaviors were evaluated by the open field test （OFT）， elevated plus maze （EPM） test， and light/dark box （LDB） test. Serum levels of corticotropin-releasing hormone （CRH）， adrenocorticotrophic hormone （ACTH）， and corticosterone （CORT） were measured via ELISA to assess stress levels. Ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） was employed to detect 9 metabolites in the brain tissue and serum metabolites. Orthogonal partial least squares-discriminant analysis （OPLS-DA） was adopted to identify differential metabolites （VIP>1.0， P<0.05）. MetaboAnalyst 5.0 was used for metabolic pathway enrichment analysis of the differential metabolites.ResultsCompared with the control group， the model group showed reductions in the central activity time and central distance in the OFT （P<0.05）， the proportions of open-arm residence time and open-arm residence times in the EPM test （P<0.01）， and the proportions of open box activity time and open box activity distance in the LDB test （P<0.05）， which were increased in the medium- and high-dose MSNS groups compared with the model group （P<0.05）. Compared with the control group， the model group showed elevated levels of CRH， ACTH， and CORT in the serum （P<0.01）， and the elevations were diminished in the medium- and high-dose MSNS groups （P<0.05）. UPLC-MS results indicated that compared with the control group， the model group presented declined DA， GABA， 5-HIAA， 5-HT， and 5-HT/Trp levels （P<0.05， P<0.01） and raised Glu， NE， Kyn， and Kyn/Trp levels （P<0.05）. Compared with the model group， high-dose MSNS increased the GABA， 5-HIAA， and 5-HT/Trp levels （P<0.05） and lowered the Glu and Kyn/Trp levels （P<0.05）. Untargeted metabolomics identified that 16 CRS-induced metabolic disturbances were reversed by MSNS. KEGG pathway analysis indicated that MSNS primarily modulated eight core pathways including alanine/aspartate/glutamate metabolism， butyrate metabolism， arginine-proline metabolism， TCA cycle， unsaturated fatty acid biosynthesis， and tryptophan metabolism. The mechanisms involved multidimensional biological processes， including neurotransmitter homeostasis regulation， TCA cycle energy metabolism optimization， and inflammatory response suppression.ConclusionMSNS alleviates CRS-induced anxiety-like behaviors in mice by mitigating hypothalamic-pituitary-adrenal axis hyperactivity， improving hippocampal neurotransmitter and tryptophan metabolic pathways， and regulating alanine/aspartate/glutamate metabolism， butyrate metabolism， arginine-proline metabolism， and TCA cycle.关键词：modified Sinisan;chronic restraint stress;anxiety;hypothalamic-pituitary-adrenal axis;metabolomics76|79|0更新时间：2025-10-09
- “最新研究发现，四神丸能改善腹泻型肠易激综合征大鼠肠屏障功能，减轻腹泻症状和结肠黏膜炎症，其机制可能与调节肠道菌群结构和代谢产物平衡有关。”摘要：ObjectiveTo investigate the effect and mechanism of Sishenwan in restoring the intestinal barrier function in the rat model of diarrhea-predominant irritable bowel syndrome （IBS-D） due to spleen-kidney Yang deficiency based on intestinal flora and short-chain fatty acids.MethodsAfter the delivery of 10 SPF-grade pregnant rats， 4 male suckling rats were kept in each litter for the experiment. The male suckling rats were randomly allocated into blank， model， low-dose （3.51 g·kg-1） Sishenwan， high-dose （7.02 g·kg-1） Sishenwan， and Peifeikang （0.54 g·kg-1） groups， with 8 rats in each group. The blank group was fed conventionally， and the other groups were subjected to mother-child separation and Sennae Folium gavage （1 g·mL-1， 10 mL·kg-1） for the modeling of IBS-D due to spleen-kidney Yang deficiency. After the modeling was completed， the rats in Sishenwan groups were administrated with the corresponding dose of Sishenwan decoction by gavage， and the Peifeikang group with bifidobacterium triple live powder+normal saline suspension. The blank and model groups were treated with an equal volume of normal saline by gavage. The general conditions and fecal characteristics of rats were observed. After 2 weeks of administration， the rats were anesthetized for sample collection. The pathological changes of the colon tissue in rats were observed by hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to measure the levels of transforming growth factor-beta （TGF-β）， interleukin-10 （IL-10）， and interleukin-22 （IL-22）. Immumohistochemical staining （IHC） was performed to detect the positive expression of zonula occludens-1 （ZO-1） and occludin in the colon tissue. Western blot was employed to determine the protein levels of ZO-1 and occludin in the colon tissue of rats， and 16S rRNA gene sequencing was performed for intestinal flora. Gas chromatography-mass spectrometry was employed to determine the content of short-chain fatty acids （SCFAs） in the cecum contents of rats.ResultsThe colon tissue in the blank group presented a clear structure， neat glands， and no inflammatory cell infiltration. In the model group， the colon tissue showcased a disorganized structure， irregular arrangement of glands， and inflammatory cell infiltration. Compared with the model group， the low-dose and high-dose Sishenwan groups and the Peifeikang group exhibited an intact colon tissue structure， regular arrangement of glands， and reduced inflammatory cell infiltration. Compared with the blank group， the modeling lowered the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.01）， down-regulated the protein levels of ZO-1 and occludin in the colon tissue （P<0.01）， and decreased the content of acetic acid and propionic acid and increased the content of butyric acid in cecum contents （P<0.05）. Compared with the model group， low-dose and high-dose Sishenwan raised the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.05， P<0.01）， and Peifeikang elevated the levels of TGF-β and IL-10 in the serum （P<0.01）. High-dose Sishenwan and Peifeikang up-regulated the protein levels of ZO-1 and occludin （P<0.05， P<0.01）， increased the content of acetic acid and propionic acid in cecum contents （P<0.05）， and decreased the content of butyric acid （P<0.05）. The 16S rRNA gene sequencing results showed that the intestinal flora structure of the model group changed compared with that of the blank group. Compared with the model group， Sishenwan and Peifeikang increased the relative abundance of Lachnospiraceae， Muribaculaceae， Akkermansiaceae， Ligilactobacillus， UBA3282， Akkermansia， and Corynebacterium while reducing the relative abundance of Oscillospiraceae， Desulfovibrionaceae， Lactobacillus， Romboutsia， and Desulfovibrio. They can restore the intestinal flora structure similar to that in the blank group.ConclusionSishenwan can alleviate diarrhea symptoms and colonic mucosal inflammation， increase the expression of tight junction proteins in the colonic mucosa， and strengthen the intestinal barrier in IBS-D rats with the syndrome of spleen-kidney Yang deficiency. The mechanism of action may be related to optimizing the structure and balance of intestinal flora and regulating the SCFAs， and the effect of high-dose Sishenwan is obvious.关键词：diarrhea-predominant irritable bowel syndrome;Sishenwan;intestinal barrier;intestinal flora;short-chain fatty acid95|77|0更新时间：2025-10-09
- “最新研究发现，健脾养正消癥方通过调控DZIP1表达，抑制成纤维细胞激活和上皮间充质转化，阻止胃癌恶性进展。”摘要：ObjectiveTo establish a subcutaneous xenograft model of gastric cancer in nude mice and to identify differentially expressed genes （DEGs） affected by Jianpi Yangzheng Xiaozheng formula （JPYZXZ） in diffuse gastric cancer （DGC） using transcriptome sequencing. The study aims to identify potential key prognostic factors and preliminarily elucidate the therapeutic mechanism of JPYZXZ.MethodsSubcutaneous tumor tissues were collected from nude mice treated with JPYZXZ （6 g·kg-1）and from the untreated traditional Chinese medicine control group. High-throughput RNA sequencing was performed to extract and analyze total RNA and identify DEGs， followed by functional enrichment analysis. DEGs were intersected with cancer-associated fibroblast （CAF）-related genes identified from single-cell RNA sequencing （scRNA-seq） data. A Cox proportional hazards regression model （Cox model） was constructed to identify potential key targets， among which DAZ interacting protein 1 （DZIP1） was selected. The role of DZIP1 in DGC progression was further verified through in vitro and in vivo experiments.ResultsTranscriptome sequencing revealed that DEGs regulated by JPYZXZ were significantly enriched in biological processes such as focal adhesion， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， and vascular development （P<0.05）. Intersection analysis with CAF marker genes identified ten potential common target genes. Cox regression analysis combined with the Cancer Genome Atlas （TCGA） dataset for stomach adenocarcinoma （STAD） confirmed that DZIP1 is an independent prognostic factor significantly associated with poor outcomes. Transcriptome and immunohistochemical analyses showed that DZIP1 expression was significantly higher in gastric cancer tissues than in adjacent tissues， while JPYZXZ treatment downregulated DZIP1 expression in a dose-dependent manner. Clinical data further demonstrated that serum DZIP1 levels in patients treated with JPYZXZ were significantly lower than those in the control group.ConclusionJPYZXZ may inhibit the malignant progression of DGC by downregulating DZIP1 expression， thereby suppressing CAF activation and epithelial-mesenchymal transition （EMT）. These findings provide experimental evidence and identify DZIP1 as a potential therapeutic target in DGC treatment.关键词：Jianpi Yangzheng Xiaozheng formula;transcriptomics;diffuse gastric cancer;DAZ interacting protein 1 （DZIP1）;epithelial-mesenchymal transition59|79|0更新时间：2025-10-09
- “最新研究发现，虎杖通过调节肺表面活性脂质平衡，有效降低RSV感染小鼠病毒载量，改善肺部炎症。”摘要：ObjectiveTo investigate the efficacy and mechanism of Polygoni Cuspidati Rhizoma et Radix （Huzhang） in treating respiratory syncytial virus（RSV） infection by regulating pulmonary surfactant lipid homeostasis through lipidomics.MethodsSixty BALB/c mice were randomly divided into the blank group， model group， positive group（ribavirin group， 46 mg·kg-1）， and low- and high-dose Huzhang groups（0.75， 2.25 g·kg-1）， with 12 mice in each group. Except for the blank group， all other groups were infected with RSV via intranasal instillation. The drug intervention groups were given corresponding doses of drug by gavage for 3 consecutive days， while normal saline was used in the blank and model groups. Hematoxylin-eosin（HE） staining was used to observe pathological changes in mouse lung tissue. Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was employed to detect viral loads［RSV-nucleoprotein（N） and RSV-glycoprotein（G） mRNA］ and inflammatory factor levels［interleukin（IL）-1β and tumor necrosis factor（TNF）-α mRNA］ in the lung tissue. Mouse bronchoalveolar lavage fluid was collected to detect the levels of pulmonary surfactant lipids through ultra-high performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap-MS）， followed by principal component analysis and differential lipid identification.ResultsCompared with the blank group， the model group exhibited extensive inflammatory cell infiltration， congestion， and tissue damage in the lungs， and the pathological score and lung index of lung tissue significantly increased（P<0.01）， along with significantly elevated mRNA expressions of RSV-N， RSV-G， IL-1β， and TNF-α（P<0.01）. Compared with the model group， different doses of Huzhang and ribavirin significantly reduced the pathological scores of the lung tissue and lung index（P<0.01）. In addition， the mRNA levels of RSV-N， RSV-G and TNF-α in the lungs significantly decreased in the Huzhang high dose group（P<0.01）. Lipidomics analysis identified multiple significantly changed differential metabolites. Compared with the blank group， the model group showed obvious abnormal lipid metabolism， which was manifested by the elevated levels of prostaglandin（PG）， ceramide（Cer）， phosphatidylcholine（PC）， phosphatidylethanolamine（PE）， phosphatidylinositol（PI）， sphingomyelin（SM）， and the decreased levels of diglycerides（DG） and acylethanolamine（NAE）. After the intervention of low dose of Huzhang， the above lipid metabolites showed a significant reversal trend， while the intervention of high dose of Huzhang could regulate levels of PI lipids， PG lipids and PC lipids.ConclusionHuzhang can significantly reduce the viral load of lung tissue and improve lung inflammation in RSV-infected mice. The underlying mechanism may be related to the maintenance of homeostasis in pulmonary surfactant lipids such as PI and PG.关键词：respiratory syncytial virus（RSV）;Polygoni Cuspidati Rhizoma et Radix;pulmonary surfactant lipids;lipidomics;metabolomics;viral pneumonia58|64|0更新时间：2025-10-09
- “菟丝子总黄酮能显著改善小鼠抑郁行为，调节神经递质，抑制炎症，促进海马神经元修复，抗抑郁效果优于菟丝子。”摘要：ObjectiveTo investigate the antidepressant effects and mechanisms of total flavonoids from Cuscutae Semen （TFCC） in the mouse model of chronic unpredictable mild stress （CUMS）.MethodsFifty male 4-week-old ICR mice were randomized into five groups （n=10 per group）： blank control， model， Cuscutae Semen decoction （10.2 g·kg-1·d-1）， paroxetine （2.6 mg·kg-1·d-1）， and TFCC （173.2 mg·kg-1·d-1）. The other groups except the blank control group underwent chronic unpredictable mild stress （CUMS） for 4 weeks. Behavioral assessments were conducted post-modeling. Then， the model group received distilled water （10 mL·kg-1·d-1）， while treatment groups were administrated with respective agents via oral gavage （10 mL·kg-1） for 4 weeks. Depression-like behaviors were evaluated by the sucrose preference test （SPT）， forced swimming test （FST）， and tail suspension test （TST）. Hippocampal neuronal morphology was observed via hematoxylin-eosin staining， and apoptosis in the brain tissue was assessed via terminal- deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling （TUNEL）. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the hippocampal levels of inflammatory cytokines ［interleukin （IL）-1β， IL-6， and TNF-α）］ and neurotransmitters ［5-hydroxytryptamine （5-HT）， dopamine （DA）， and brain-derived neurotrophic factor （BDNF）］， while the reactive oxygen species （ROS） levels were quantified via the DCFH-DA probe. Real-time PCR was performed to measure the mRNA levels of NOD-like receptor protein 3 （NLRP3）， apoptosis-associated Speck-like protein containing a CARD （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， IL-1β， and inducible nitric oxide synthase （iNOS）. Western blot was employed to evaluate the protein levels of NLRP3， ASC， Caspase-1， uncoupling protein 2 （UCP2）， and thioredoxin-interacting protein （TXNIP）.ResultsCompared with the blank control group， the model group exhibited weight loss （P<0.01）， reduced sucrose preference （P<0.01）， prolonged immobility time in FST and TST （P<0.01）， neuron disarrangement with nuclear pyknosis in hippocampal CA3 region， increased apoptosis in the brain tissue， elevated levels of IL-1β， IL-6， and TNF-α （P<0.01）， declined levels of 5-HT， DA， and BDNF （P<0.01）， increased ROS accumulation （P<0.01）， upregulated mRNA levels of NLRP3， ASC， Caspase-1， IL-1β， and iNOS （P<0.01）， down-regulated protein level of UCP2 （P<0.01）， and up-regulated protein levels of NLRP3， ASC， Caspase-1， and TXNIP （P<0.01）. Compared with the model group， the interventions restored sucrose preference （P<0.01）， shortened immobility time （P<0.01）， repaired hippocampal neuronal structure， reduced apoptosis， lowered the levels of inflammatory cytokines （P<0.01）， restored the levels of neurotransmitters （P<0.01）， alleviated ROS accumulation （P<0.01）， downregulated the mRNA levels of NLRP3， ASC， Caspase-1， IL-1β， and iNOS （P<0.01）， upregulated the protein level of UCP2 （P<0.01）， and reduced the protein levels of NLRP3， ASC， Caspase-1， and TXNIP （P<0.01）. Moreover， TFCC outperformed Cuscutae Semen decoction in ameliorating depressive behaviors. TFCC excelled in neuronal repair， neurotransmitter regulation， anti-inflammatory effects， and modulation of the UCP2/TXNIP/NLRP3 pathway （P<0.05）.ConclusionTFCC modulates the hippocampal UCP2/TXNIP/NLRP3 pathway to inhibit inflammasome activation， reduce oxidative stress， restore neurotransmitters， thus suppressing neuronal apoptosis and promoting the rearrangement and morphology recovery of hippocampal cells. It outperforms Cuscutae Semen decoction in the antidepressant efficacy.关键词：Cuscutae Semen;total flavonoids;depression;uncoupling protein 2/thioredoxin-interacting protein/NOD-like receptor protein 3 （UCP2/TXNIP/NLRP3） signaling pathway;oxidative stress-inflammation axis91|83|0更新时间：2025-10-09
- “最新研究显示，祛瘀解毒法能有效改善肾虚血瘀型子宫内膜异位症患者症状，降低血清CA125水平，提高胚胎质量和妊娠率，可能通过调节JNK、c-Jun、NR4A2蛋白表达发挥作用。”摘要：ObjectiveTo observe the clinical efficacy of the stasis-dispelling and detoxifying therapy in endometriosis （EMs） patients with the syndrome of kidney deficiency and blood stasis and the effects of this therapy on the expression levels of proteins related to the c-Jun N-terminal kinase （JNK） signaling pathway.MethodsA total of 72 patients with EMs due to kidney deficiency and blood stasis who met the criteria at the Integrated Traditional Chinese and Western Medicine Center for Reproduction and Genetics of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from March 2024 to February 2025 were selected and randomized into a treatment group and a control group， with 36 patients in each group. Another 36 patients undergoing in vitro fertilization-embryo transfer （IVF-ET） due to male factors alone were selected as the blank group. The treatment group took the Zishen Quyu Jiedu formula orally， while the control group and the blank group took placebos. The treatment course encompassed the cycle before ovarian stimulation and the oocyte retrieval cycle. The TCM syndrome score of kidney deficiency and blood stasis， as well as the serum level of cancer antigen 125 （CA125）， were evaluated at the time of enrollment （before treatment） and on the trigger day （after treatment）. Serum levels of sex hormones were measured on day 2 of the menstrual cycle. On the trigger day， the duration and dosage of gonadotropin （Gn） administration and the serum levels of hormones on the day of human chorionic gonadotropin （HCG） injection were assessed. Embryo outcomes were evaluated 3 days after oocyte retrieval， and clinical pregnancy rates were assessed 28 days after embryo transfer. The baseline data of three groups were observed. The TCM syndrome scores and serum CA125 levels before and after treatment were compared between the treatment and control groups. The baseline endocrine levels， Gn days， Gn dosage， hormone levels on the day of HCG administration， number of oocytes retrieved， number of 2 pronucleus （2PN） fertilizations， number of available embryos， high-quality embryo rate， and clinical pregnancy rate were also assessed in all three groups. Six patients from each group were selected for determination of the protein levels of JNK， c-Jun， and nuclear receptor subfamily 4 group A member 2 （NR4A2） in ovarian granulosa cells （GCs） on the day of oocyte retrieval by Western blot.Results（1） There were no statistically significant differences in the baseline data among three groups， indicating comparability. （2） Compared with the baseline within the same group， the treatment group showed a decrease in the syndrome score of kidney deficiency and blood stasis after treatment. After treatment， serum CA125 levels decreased in both groups （P<0.05）， with a more substantial reduction in the treatment group， resulting in a difference between the two groups （P<0.05）. （3） There were no significant differences among three groups in terms of baseline serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E2）， and progesterone （P）， as well as the duration and dosage of Gn administration and the serum levels of LH， E2， and P on the day of HCG administration. （4） For embryo outcomes， the number of oocytes retrieved， 2PN fertilizations， available embryos， and high-quality embryo rates in the treatment group and the blank group were higher than those in the control group （P<0.05）， and the treatment group and the blank group had similar 2PN fertilizations. （5） There were differences in clinical pregnancy rate among three groups （P<0.05）， and the treatment group had higher pregnancy rate than the control and blank groups. （6） The protein levels of JNK， c-Jun， and NR4A2 in the GCs of the treatment group were lower than those in the control group （P<0.01） and close to those in the blank group （P<0.01）. （7） No obvious adverse reactions were observed in any of the subjects during the clinical observation process.ConclusionZishen Quyu Jiedu formula can ameliorate the clinical symptoms of patients with EMs due to kidney deficiency and blood stasis， reduce the serum CA125 level， increase the number of oocytes retrieved， 2PN fertilizations， available embryos， and high-quality embryo rate， and improve pregnancy outcomes. The mechanism may involve downregulating the levels of JNK， c-Jun， and NR4A2 to reduce the apoptosis of ovarian GCs and improve the ovarian function in the patients.关键词：stasis-dispelling and detoxifying therapy;endometriosis;kidney deficiency and blood stasis;Zishen Quyu Jiedu formula;cell apoptosis63|63|0更新时间：2025-10-09
- “最新研究揭示，脾气亏虚、湿热瘀毒证结直肠癌患者存在特有的代谢产物和信号通路，为早期诊断和治疗提供新思路。”摘要：ObjectiveTo observe and analyze the plasma metabolite differences among colorectal cancer patients with spleen-qi deficiency， damp-heat stasis-toxin syndrome（SRYD）， non-spleen-qi deficiency， damp-heat stasis-toxin syndrome（non-SRYD）， and normal human beings（Normal）， aiming to identify unique metabolites specific to SRYD colorectal cancer patients and their potential biomarkers.MethodsBased on the diagnostic criteria of SRYD and non-SRYD colorectal cancer， 30 patients were included， including 10 patients with SRYD colorectal cancer and 20 patients with non-SRYD colorectal cancer， while 10 individuals were recruited for the Normal group. Metabolome sequencing of plasma from the three groups was performed by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap mass spectrometry（UPLC-Q-Exactive-Orbitrap-MS）. Multivariate statistical analysis were performed by principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）， and the intergroup differential metabolites were identified based on variable importance in the projection（VIP） value>1 and t-test P<0.05. And pathway enrichment analysis based on Kyoto Encyclopedia of Genes and Genomes（KEGG） was performed to explore the metabolites and metabolic pathways specific to SRYD colorectal cancer patients.ResultsMetabolome sequencing results showed some differences in metabolic profiles between the groups. A total of 111 plasma differential metabolites were found in the SRYD group and the Normal group， of which 31 were up-regulated and 80 were down-regulated， mainly including stearoyl lysophosphatidylcholine， indole-3-acrylic acid， and dehydroepiandrosterone sulfate（P<0.05）. The non-SRYD group exhibited 97 differentially expressed metabolites compared to the Normal group， with 36 up-regulated and 61 down-regulated， mainly including stearoyl lysophosphatidylcholine， sphingosine， and palmitoyl lysophosphatidylcholine（P<0.05）. And the SRYD group exhibited 19 differentially expressed metabolites compared to the non-SRYD group， of which 5 were up-regulated and 14 were down-regulated， mainly including dihydrosphingosine， palmitic acid， and linoleoylethanolamide（P<0.05）. The significant differential metabolites were subjected to KEGG analysis to obtain significantly enriched metabolic pathways in each group， and the results showed that 11 metabolic pathways such as primary bile acid synthesis， cholesterol metabolism and bile secretion were differential signaling pathways specific to SRYD colorectal cancer. Further retrieval of the above key signaling pathways showed that bile acids were up-regulated in both bile secretion and primary bile acid synthesis pathways， and there was a trend of up-regulation of glycochenodeoxycholic acid， taurochenodeoxycholic acid， and chenodeoxycholic acid.ConclusionPrimary bile acid synthesis， cholesterol metabolism， and bile secretion-related pathways may be differential signaling pathways specific to SRYD colorectal cancer， and bile acid is a core molecule in the metabolic pathway， which can serve as potential biomarkers closely related to the development and progression of SRYD colorectal cancer.关键词：colorectal cancer;spleen-Qi deficiency， damp-heat stasis-toxin syndrome;plasma metabolomics;bile acids;ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap mass spectrometry（UPLC-Q-Exactive-Orbitrap-MS）49|53|0更新时间：2025-10-09
- “在特应性皮炎治疗领域，研究者通过证据图梳理中药内服治疗的临床随机对照试验，发现中医药治疗已成为研究热点，但存在临床定位不明确、研究质量待提高等问题。”摘要：ObjectiveTo characterize the evidence distribution and methodological quality of randomized controlled trials （RCTs） on oral Chinese herbal medicine （CHM） for atopic dermatitis （AD） based on evidence mapping.MethodsSeven databases （CNKI， Wanfang Data， VIP， CBM， Cochrane Library， PubMed， and Embase） and the Chinese Clinical Trial Registry were searched for the RCTs in Chinese and English. Evidence distribution was presented graphically and textually， and methodological quality was assessed via the Cochrane Risk of Bias tool （ROB 1.0）.ResultsA total of 168 RCTs were included. The number of annual publications showing an increasing trend， and 72.6% RCTs had sample sizes of 51-100 participants. The studies evaluated 108 distinct CHM interventions categorized as decoctions， granules， Chinese patent medicines， and extracts. Compound Glycyrrhizin was the most frequently used， followed by Xiaofengsan and Chushi Weiling decoction. Among the RCTs， 57.1% had the treatment courses of 4-8 weeks. Outcome measures predominantly focused on clinical response rate， skin lesion severity scores， and adverse events， with less attention to TCM symptom scores， skin barrier function， and relapse rates. The overall risk of bias was generally high.ConclusionWhile CHM for AD is a research hotspot and demonstrates clinical advantages， the related studies have problems such as unclear clinical positioning， poor research standardization and methodological quality， and insufficient prominence of TCM clinical advantages. Large-sample， methodologically rigorous， and high-quality studies are needed to enhance the evidence base for CHM in treating AD.关键词：Chinese herbal medicine;atopic dermatitis;evidence mapping;randomized controlled trial;evidence-based research90|238|0更新时间：2025-10-09
- “在乳块消制剂质量评价领域，专家建立了多指标多方法检测体系，为提升药品质量提供解决方案。”摘要：ObjectiveBased on multi-index and multi-method detection， the quality of Rukuaixiao preparations was systematically evaluated from the perspective of characteristic components， and the existing problems were analyzed.MethodsLiquid chromatography-mass spectrometry（LC-MS） for the determination of 16 characteristic components was established to evaluate the quality of 129 batches of Rukuaixiao preparations. High performance liquid chromatography（HPLC） was established to determine the contents of salvianolic acids and tanshinones， investigate the rationality of quality control index of Salviae Miltiorrhizae Radix et Rhizoma in the standard for Rukuaixiao preparations in the 2020 edition of Pharmacopoeia of the People's Republic of China（hereinafter referred to as Chinese Pharmacopoeia） （volume Ⅰ）， and trace the causes of significant difference among different batches. The processing and different extraction methods of Vaccariae Semen were tested， analyzing the impact of formulation changes across different editions of Chinese Pharmacopoeia. The LC-MS was established for determining the changes in the ratio of toosendanin and isotoosendanin after water extraction of Toosendan Fructus. The contents of active components in different parts of Gleditsiae Spina were determined to identify the reason of the low contents of characteristic components in some enterprises.ResultsBased on the comprehensive analysis of the samples from different dosage forms， the contents of characteristic components of Vaccariae Semen and Gleditsiae Spina in tablets from manufacturer B and granules from manufacturer D were significantly higher than those in tablets from manufacturer A， and tablets and capsules from manufacturer C. The contents of tanshinones in some batches of products from manufacturer A were abnormally high， potentially linked to the use of 70% ethanol reflux during extraction of Salviae Miltiorrhizae Radix et Rhizoma. All samples from manufacturer C exhibited abnormally high proportions of salvianic acid A and 3，4-dihydroxybenzaldehyde（salvianolic acid degradation products） to the total seven phenolic acids， indicating a risk of blindly pursuing tanshinol content and neglecting more effective components. The extraction rate of the characteristic components from Vaccariae Semen by decocting with water was obviously higher than that by reflux extraction with 70% ethanol. However， using the stir-fried Vaccariae Semen could reduce the loss of ingredients. The content ratio of toosendanin and isotoosendanin decreased from the crude herb to the prepared medicine when Toosendan Fructus was prepared by water decoction. The reason for the low component content of Gleditsiae Spina may be attributed to manufacturers using excessive non-medicinal parts in their formulations.ConclusionIt is suggested that enterprises should ensure the quality of raw material inputs， especially those without quality-control items in the standard， reduce the use of non-medicinal parts， and prohibit arbitrary alterations to manufacturing methods or processes. It is also recommended that Vaccariae Semen in Rukuaixiao capsules and granules should be changed to the stir-fried processed products. Isotoosendanin should be taken into consideration in the drug supervision when Toosendan Fructus is prepared into medicine by water decoction. Salvianolic acid B should be set as a quality control index for Salviae Miltiorrhizae Radix et Rhizoma when revising the pharmacopoeia standard of Rukuaixiao preparations.关键词：Rukuaixiao preparations;phenolic acids;Vaccariae Semen;Gleditsiae Spina;Tanshinone;isotoosendanin;quality evaluation48|56|0更新时间：2025-10-09

After research， Huoxiang Zhengqisan， also known as Huoxiang Zhengqitang， was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium， 41.3 g of Angelicae Dahuricae Radix， 41.3 g of Perilla frutescens（actually Perillae Folium）， 41.3 g of Poria， 82.6 g of Pinelliae Rhizoma， 82.6 g of Atractylodis Macrocephalae Rhizoma， 82.6 g of Citri Reticulatae Pericarpium（actually Citri Exocarpium Rubbum）， 82.6 g of Magnoliae Officinalis Cortex， 82.6 g of Platycodonis Radix， 123.9 g of Pogostemonis Herba， and 103.25 g of Glycyrrhizae Radix et Rhizoma. In this formula， Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products， Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products， and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose， take 8.26 g of the powdered formula， add 300 mL of water， along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus， and decoct until reduced to 140 mL. The decoction should be administered hot， with three times daily. To induce sweating， the patient should be kept warm under a quilt， and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness， regulate Qi and harmonize the middle， which is mainly used to treat a series of diseases of digestive and respiratory systems. However， potential adverse reactions， including allergies， purpura and disulfiram-like reactions， should be considered during clinical use. Huoxiang Zhengqisan features a rational composition， extensive clinical application， and strong potential for further research and development.关键词：Huoxiang Zhengqisan;key information;modern applications;textual research;formula composition;origin;dosage;clinical application138|127|0更新时间：2025-10-09
- “最新研究发现，黄连知母汤能显著改善2型糖尿病糖脂代谢紊乱，降低胰岛素抵抗，可能通过调控PI3K/Akt信号通路发挥作用。”摘要：ObjectiveBased on the phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， the effects of Huanglian Zhimutang on glucose and lipid metabolism disorders and hepatic insulin resistance （IR） with type 2 diabetes mellitus （T2DM） were investigated.MethodsGoto-Kakizaki （GK） rats were fed a high-fat diet to induce a T2DM rat model and then randomly divided into four groups： normal control group， model control group， metformin group （0.10 g·kg-1）， and Huanglian Zhimutang group （3.60 g·kg-1）， with eight rats in each group. Drug intervention was administered continuously for 8 weeks. Serum and liver tissues were collected from each group. Fasting insulin （FINS） levels were measured using enzyme-linked immunosorbent assay （ELISA）， and the homeostasis model assessment of insulin resistance （HOMA-IR） index was calculated. Total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） levels were measured using an automatic biochemical analyzer. Liver tissue pathology was observed via hematoxylin-eosin （HE） staining. Serum interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） levels were detected using ELISA. Network pharmacology and transcriptomics sequencing were combined to analyze differentially expressed genes （DEGs） in liver tissue from the normal control group， model control group， and Huanglian Zhimutang group. Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis was performed to identify pathways affected by Huanglian Zhimutang intervention in T2DM. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to assess the mRNA expression of insulin receptor substrate-1 （IRS-1）， PI3K， Akt， and peroxisome proliferator-activated receptor gamma （PPARγ） in liver tissue， while Western blot was used to evaluate corresponding protein expression levels.ResultsAfter 8 weeks of Huanglian Zhimutang intervention， typical symptoms of T2DM rats such as polydipsia， polyphagia， and polyuria were significantly alleviated， along with reductions in fasting blood glucose levels and insulin resistance（P<0.01）. Histopathological results revealed that Huanglian Zhimutang effectively improved hepatic steatosis and inflammatory edema and reduced lipid vacuole formation. Biochemical tests demonstrated that Huanglian Zhimutang significantly reduced serum levels of TC， TG， and LDL-C（P<0.01）. ELISA results showed that Huanglian Zhimutang effectively decreased serum concentrations of IL-6 and TNF-α（P<0.05，P<0.01）. Combined network pharmacology predictions with KEGG pathway analysis of transcriptomics showed that DEGs between the Huanglian Zhimutang and model control groups were significantly enriched in the PI3K/Akt signaling pathway. Real-time PCR and Western blot results confirmed that Huanglian Zhimutang upregulated the expression of PI3K/Akt signaling pathway-related mRNAs and proteins in liver tissue（P<0.05，P<0.01）， thereby reducing inflammation， alleviating hepatic lipid accumulation， and enhancing insulin sensitivity.ConclusionHuanglian Zhimutang effectively ameliorates glucose and lipid metabolism disorders in T2DM rats. Its mechanism may be related to the regulation of the PI3K/Akt pathway， which reduces inflammation and hepatic lipid deposition and relieves hepatic insulin resistance.关键词：Huanglian Zhimutang;type 2 diabetes mellitus;phosphoinositide 3-kinase /protein kinase B pathway;network pharmacology;transcriptomics78|55|0更新时间：2025-10-09

Except the control group， other groups were modeled for Hp infection. Mice were administrated with LPYJWF at corresponding doses by gavage. Quadruple therapy group was given omeprazole （6.06 mg·kg-1·d-1） + amoxicillin （303 mg·kg-1·d-1） + clarithromycin （151.67 mg·kg-1·d-1） + colloidal pectin capsules （30.3 mg·kg-1·d-1） by gavage. The control group was given an equal volume of 0.9% NaCl for 14 days. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of gastric mucosa， and Warthin-Starry （W-S） silver staining was used to detect Hp colonization. Transmission electron microscopy was employed to observe the mitochondrial ultrastructure of the gastric tissue， and immunofluorescence co-localization assay was adopted to detect the expression of mitochondrial transcription factor A （TFAM） and translocase of the outer mitochondrial membrane member 20 （TOMM20）. The water-soluble tetrazolium salt method and thiobarbituric acid method were used to determine the levels of superoxide dismutase （SOD） and malondialdehyde （MDA）， respectively， in the gastric tissue. Western blot was employed to measure the protein levels of PTEN-induced kinase 1 （PINK1）， Parkin， p62， microtubule-associated protein 1 light chain 3 （LC3）， NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a CARD （ASC）， interleukin-1β （IL-1β）， and interleukin-18 （IL-18）. Real-time quantitative PCR was employed to assess the mRNA levels of PINK1， Parkin， p62， and LC3.ResultsCompared with the control group， the model group presented obvious gastric mucosal damage， colonization of a large number of Hp， severe mitochondrial damage， vacuolated structures due to excessive autophagy， reduced TOMM20 and TFAM co-expression in the gastric mucosal tissue， and reduced SOD and increased MDA （P<0.01）. In addition， the gastric tissue in the model group showed up-regulated protein and mRNA levels of PINK1， Parkin， and LC3 and down-regulated protein and mRNA levels of p62 （P<0.01， as well as increased expression of inflammasome-associated proteins NLRP3， ASC， IL-1β， and IL-18 （P<0.01）. Compared with the model group， the LPYJWF and quadruple therapy groups showed alleviated pathological damage of gastric mucosa， reduced Hp colonization， mitigated mitochondrial damage， and increased co-expression of TOMM20 and TFAM. The SOD level was elevated in the LPYJWF-L group （P<0.01）， and the MDA levels became lowered in the LPYJWF and quadruple therapy groups （P<0.05， P<0.01）. Furthermore， the LPYJWF and quadruple therapy groups showed down-regulated mRNA levels of PINK1， Parkin， and LC3 and protein levels of PINK1 and Parkin， and up-regulated mRNA level of p62 （P<0.01）. The LPYJWF-M， LPYJWF-H， and quadruple therapy groups showcased down-regulated LC3 Ⅱ/LC3 Ⅰ level （P<0.05， P<0.01） and up-regulated protein level of p62 （P<0.01）. The expression of inflammasome-associated proteins NLRP3， ASC， IL-1β， and IL-18 were reduced in the LPYJWF and quadruple therapy groups （P<0.05， P<0.01）.ConclusionLPYJWF ameliorates gastric mucosal damage and exerts mucosa-protective effects in Hp-infected mice， which may be related to the inhibition of excessive mitochondrial autophagy， thereby inhibiting the activation of the NLRP3 inflammasome pathway.关键词：Helicobacter pylori;gastritis;modified Lianpoyin formula;mitochondrial autophagy;NOD like receptor protein 3（NLRP3） inflammasome59|76|0更新时间：2025-10-09
- “最新研究揭示，甘露消毒丹通过抑制病毒性肺炎小鼠炎性反应改善肺损伤，作用机制可能与抑制PI3K/Akt通路活化有关。”摘要：ObjectiveTo explore the mechanisms of action of Ganlu Xiaodu Dan in treating viral pneumonia by combining network pharmacology and molecular docking with in vivo experimental validation.MethodsNetwork pharmacology and molecular docking were used to predict the core components， target genes， and major pathways of Ganlu Xiaodu Dan. Molecular docking was then applied to verify the interactions between the core components and key targets. Sixty male C57BL/6 mice were randomly divided into six groups （n = 10 per group）， including blank， model， dexamethasone， and Ganlu Xiaodu Dan low-， medium-， and high-dose groups. The blank and model groups were gavaged with physiological saline （10 mL·kg-1） every 12 h. The dexamethasone group received intraperitoneal injections of dexamethasone （5 mg·kg-1）. The low-， medium-， and high-dose groups of Ganlu Xiaodu Dan were gavaged with solutions at concentrations of 7.2， 14.4， and 21.6 g·kg-1， respectively， every 12 h. Lung wet/dry weight ratio （W/D） was measured. Hematoxylin-eosin （HE） staining was used to observe pathological changes in lung tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the expression levels of tumor necrosis factor-α （TNF-α）， interleukin （IL）-17， and IL-1β in bronchoalveolar lavage fluid （BALF）. Western blot was performed to detect the expression of phosphoinositide 3-kinase （PI3K） and protein kinase B （Akt） in lung tissue for further validation.ResultsTwelve potential active components of Ganlu Xiaodu Dan were identified through network pharmacology. A total of 306 overlapping target genes were obtained between Ganlu Xiaodu Dan and viral pneumonia. PPI network analysis identified the top 20 key targets， and GO and KEGG enrichment analyses revealed the top 20 signaling pathways. An “active component–target–pathway” network was constructed. Molecular docking demonstrated strong affinity between the core components of Ganlu Xiaodu Dan and key targets related to viral pneumonia. In animal experiments， compared with the blank group， the model group showed severe bronchial epithelial damage， disordered alveolar structure， massive inflammatory cell infiltration， widened alveolar septa， and obvious interstitial edema. W/D， levels of IL-1β， TNF-α， and IL-17 in BALF， and protein expression of p-PI3K/PI3K and p-Akt/Akt in lung tissue were all significantly increased （P<0.05）. Compared with the model group， lung injury in the Ganlu Xiaodu Dan groups and the dexamethasone group was alleviated. W/D and TNF-α levels were significantly decreased （P<0.05）. IL-1β and IL-17 levels were significantly reduced in the medium- and high-dose groups and the dexamethasone group， and the protein expression levels of p-PI3K/PI3K and p-Akt/Akt in lung tissue were significantly decreased （P<0.05）.ConclusionGanlu Xiaodu Dan can alleviate lung injury in viral pneumonia by suppressing the inflammatory response， and its mechanism may be related to the inhibition of PI3K/Akt pathway activation.关键词：network pharmacology;molecular docking;Ganlu Xiaodu Dan;viral pneumonia;phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway82|56|0更新时间：2025-10-09

Hematoxylin-eosin （HE） staining was used to observe the pathological changes of the colon tissue. Western blot was employed to detect the expression of ZO-1 （a protein in the tight junction） and Occludin in the colon tissue， as well as the changes of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）.ResultsCompared with the blank group，the DAI scores of the mice in the model group were significantly higher （P<0.05），and the histopathological sections of their colon tissues showed mucosal damage，glandular atrophy，disordered arrangement，and a large number of inflammatory cells infiltration，and the expression of ZO-1 and Occludin proteins in their colon tissues was significantly down-regulated （P<0.05，P<0.01）. The expression of inflammatory factors TNF-α and IL-1β was significantly up-regulated （P<0.05，P<0.01）. Compared with the model group，the DAI scores of mice in all dosing groups decreased significantly （P<0.05），with the most significant effect in the regular dose group. After 7 d of drug administration，the regular dose group had the best impact on the repair of colonic mucosa in the AE mouse model. The regular dose group significantly down-regulated the expression of TNF-α （P<0.05） and significantly up-regulated the expression of ZO-1 protein （P<0.05）. The doubled-dose Puerariae Lobatae Radix group significantly down-regulated the expression of IL-1β protein （P<0.01），and there was no significant difference between all dosing groups and the model group in terms of the expression of Occludin protein. After 14 d of drug administration，the best effect on the repair of colonic mucosa in the AE mouse model was observed in the doubled dose Puerariae Lobatae Radix group. All groups except the non-Puerariae Lobatae Radix group significantly down-regulated the expression of TNF-α （P<0.01）. Meanwhile，the regular dose group and doubled-dose Puerariae Lobatae Radix group significantly elevated the expression level of Occludin protein （P<0.01）. The doubled-dose Puerariae Lobatae Radix group also significantly inhibited the expression of IL-1β protein （P<0.05） and up-regulated ZO-1 protein expression （P<0.05）.ConclusionGegen Qinliantang can reduce the pathological damage of colon tissue， protect the barrier function and structure of intestinal epithelial cells， and reduce the expression of inflammatory factors， so as to achieve the therapeutic effect of AE model mice. When comparing the therapeutic efficacy of Gegen Qinliantang containing different Gegen contents， Gegen Qinliantang with the proportion of the original formula of Zhongjing was the most effective in AE model mice.关键词：Gegen Qinliantang;acute enteritis;quantitative-effect relationship;inflammatory factor;tight junction protein85|76|0更新时间：2025-10-09 - “最新研究发现，麻黄附子甘草汤及其单药成分能有效修复足细胞损伤，减少蛋白尿，抑制TRPC5-RAC1前馈循环损伤。”摘要：ObjectiveTo investigate the molecular mechanisms of Mahuang Fuzi Gancao Tang and its pungent single herbs， Ephedrae Herba and Aconiti Lateralis Radix Praeparaia， in repairing podocyte injury based on the sweat pore theory， with a focus on the podocyte cytoskeletal transient receptor potential canonical 5 （TRPC5）-Ras-related C3 botulinum toxin substrate 1 （RAC1） feedforward loop.MethodsAn animal model with puromycin aminonucleoside （PAN）-induced overexpression of TRPC5 was established.

Syndrome Differentiation and Treatment of Polycystic Ovary Syndrome with Classical Formula： A Review AI导读
“据最新研究，多囊卵巢综合征（PCOS）治疗中，经方显示出独特实用和科学价值，疗效显著且不良反应少。”摘要：Polycystic ovarian syndrome （PCOS） is a common endocrine and metabolic disease mainly occurring among women of childbearing age. Its main symptoms include menstrual disorders， acne， hirsutism， infertility， oily skin， acanthosis nigricans， and obesity. Currently， the etiology and pathogenesis of PCOS remain unclear. Classical formulas， which have rigorous compatibility， concise composition， precise alignment with syndromes， and definitive therapeutic effects， demonstrate unique practical and scientific value in the treatment of PCOS. These formulas exhibit significant clinical efficacy， mild adverse effects， and sustained therapeutic outcomes. To explore the current status and mechanisms of classical formulas in treating PCOS， on the basis of Zhang Zhongjing's academic thoughts on gynecological diseases， this paper reviewed the relevant literature on the treatment of PCOS with classical formulas in recent years. The findings reveal that the pathogenesis of PCOS predominantly involves a combination of internal deficiency and superficial excess， closely related to dysfunction of the liver， spleen， and kidney. The root cause lies in deficiency， and on this basis， there are also symptoms of qi stagnation， blood stasis， phlegm obstruction， and dampness encumbrance. Commonly used classical formulas for treating this disease include Guizhi Fuling pills， Danggui Shaoyao powder， Wenjing decoction， and Jingui Shenqi pills. These classical formulas have good clinical efficacy in treating PCOS. Their mechanisms of action may be related to improving serum levels of sex hormones， increasing the dominant follicle diameter and endometrial thickness， alleviating insulin resistance， lowering glucose and lipid metabolism， inhibiting oxidative and inflammatory reactions in the ovarian tissue， regulating the intestinal flora， correcting the flora disorder， protecting the intestinal barrier function， and regulating the phosphatidylinositol 3-kinase/protein kinase B signaling pathway. The above research results can help doctors use classical formulas flexibly， broaden diagnostic and therapeutic approaches for PCOS and provide ideas for improving the traditional Chinese medicine diagnosis and treatment plan for PCOS.关键词：polycystic ovarian syndrome;classical formulas;thinking of syndrome differentiation and treatment;etiology and pathogenesis;research progress88|192|0更新时间：2025-10-09 - “据最新研究，百部药材历史沿革被系统梳理，为经典名方开发提供参考。”摘要：This article systematically reviews and verifies the historical evolution of Stemonae Radix from the aspects of name， origin， harvesting and processing， quality and others by consulting ancient and modern literature， in order to provide reference for the development and utilization of famous classical formulas containing this medicinal herb. Stemonae Radix has a long history of application， and it derives its name from its distinctive growth pattern， featuring clusters of ten to several dozen underground tuberous roots. This morphology resembles that of certain plants in the genus Asparagus， leading to historical instances where tuberous roots from genus Asparagus were mistakenly used as Stemonae Radix. After the research， it can be concluded that Stemonae Radix was first recorded in Mingyi Bielu， and throughout history， Baidu has been recognized as its official name， though it also bears alternative names such as Baibing， Pofucao and Ye Tianmendong. The mainstream sources used throughout history have been the dried tuberous roots of Stemona sessilifolia， S. japonica or S. tuberosa from the family Stemonaceae. This aligns with the 2025 edition of Pharmacopoeia of the People's Republic of China（hereinafter referred to as Chinese Pharmacopoeia）. Additionally， Asparagus filicinus and A. officinalis from the genus Asparagus are common sources of confusion with Stemonae Radix. The three primitive plants are mainly distributed in the Yangtze River basin and southern China， exhibiting a wide distribution. Historically， wild harvesting was predominant， but cultivation is now established. In ancient times， the harvesting time was mostly in the second， third， and eighth lunar months， when roots were harvested and dried. Nowadays， it is more common to pick and excavate in the spring and autumn seasons. After excavation， the roots are washed， fibrous roots removed， briefly blanched in boiling water or steamed until no white core remains， and then sun-dried or oven-dried. In ancient times， the processing of Stemonae Radix primarily involved roasting（stir-frying）， wine roasting， or raw materials. Modern mainstream processing specifications include two types of raw and honey-roasted products. In terms of quality evaluation of the medicinal materials， ancient criteria of "preferring plump and moist roots" align with modern requirement favoring "thick， robust stems with firm texture". Evaluating quality with authenticity， since the Song dynasty， it has been highly praised to produce in Chuzhou and Hengyang as the best. It was an ancient method of fixing the production area to stabilize the medicinal origin， reflecting the ancient recognition of the therapeutic efficacy of plants belonging to the genus Stemona. The main functions of Stemonae Radix remain consistent throughout history， including relieving coughs， eliminating phlegm and parasites. Based on the research results， it is recommended that when developing famous classical formulas containing the medicinal material Stemonae Radix， the botanical source specified in the 2025 edition of Chinese Pharmacopoeia should be selected. The specific species can be determined according to the distribution of resources and the main production areas， and the origin and corresponding botanical source should be fixed. Processing methods should be chosen based on the prescription requirements. It is recommended to use raw products without specified requirements.关键词：famous classical formulas;herbal textual research;Stemonae Radix;origin;scientific name;producing area;quality107|176|0更新时间：2025-10-09
- “最新研究发现，中医药调控代谢重编程干预胃癌“炎-癌”转化过程，为防治提供新思路。”摘要：Gastric cancer （GC） has an insidious onset and is mostly diagnosed in the middle and late stages after clinical detection. It is one of the malignant tumors with high incidence and mortality rates in the world. At present， the treatment plans are optimized mainly in terms of surgery， radiotherapy， and intervention， while the endpoints of clinical trials， such as patients' overall survival， progression-free survival， and disease-free survival， are still unsatisfactory. Therefore， effectively delaying the dynamic inflammation-cancer transformation has become an urgent bottleneck in the prevention and treatment of GC. In 1920s， Professor Otto Warburg discovered the phenomenon that tumor cells can accelerate glycolysis. Since then， the abnormal metabolic network inside tumor cells has gradually entered into researchers' view， and the hot academic research topic of metabolic reprogramming has been proposed. Tumor cells can meet their own energy consumption and adapt to external changes by adjusting their metabolic pathways to achieve rapid proliferation. In recent years， traditional Chinese medicine （TCM） is resolutely pursuing innovation in inheritance and the continuous refinement of research has led to the precision-oriented transition of TCM theories. Therefore， linking TCM with the treatment of tumors and precancerous diseases has certain research connotations. The searching and review of the publications in this field revealed that the number of publications in tumor-related metabolism increased dramatically， while there were only a few studies using TCM as a therapeutic solution. The research group has long been committed to the study of precancerous lesions of gastric cancer （PLGC） in Chinese and Western medicine. This article explained the dynamic process of inflammation-cancer transformation from the perspective of spleen deficiency-Qi stagnation-collateral stasis. The molecules of hypoxia-inducible factor （HIF）-1α， cancer-Myc （c-Myc）， apolipoprotein E （APOE） and pyruvate kinase M2 （PKM2） were selected to reflect the biological connotation of inflammation-cancer transformation. The current achievements of TCM in regulating the metabolic reprogramming to intervene in inflammation-cancer transformation were summarized， with a view to providing more information for TCM to intervene in the inflammation-cancer transformation of gastric mucosa.关键词：metabolic reprogramming;glycolysis;inflammation-cancer transformation;pathogenesis;traditional Chinese medicine100|177|0更新时间：2025-10-09
- “在溃疡性结肠炎治疗领域，四神丸展现了调节脾肾阳虚型UC的临床优势，为中西医整合治疗提供理论依据。”摘要：Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.关键词：ulcerative colitis;Sishenwan;material basis;clinical application;mechanism;combination of disease and syndrome166|174|0更新时间：2025-10-09
- “结直肠癌治疗新进展：中医药调控PI3K/Akt/mTOR信号通路，抑制肿瘤增殖、侵袭与迁移，提高疗效与安全性。”摘要：Colorectal cancer （CRC） is a prevalent malignant tumor of the digestive tract， with a high incidence and high mortality. The majority of patients are diagnosed at the middle or advanced stage， which severely influences and threatens their physical health. Current treatment modalities such as surgery， radiotherapy， and chemotherapy often encounter challenges including metastasis， recurrence， and drug resistance. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway serves as a classical regulator that regulates physiological processes such as cell cycle， autophagy， apoptosis， and proliferation. Overexpression of this pathway is observed in various tumors. In the context of CRC， the activation of this pathway can facilitate the proliferation， invasion， and migration， inhibit the autophagy and apoptosis， promote the epithelial-mesenchymal transition of CRC cells， enhance angiogenesis within the tumor， and contribute to chemotherapy resistance and radiation resistance in CRC. Traditional Chinese medicine （TCM） treatment can exert an anti-CRC effect by inhibiting this pathway， thereby improving clinical efficacy and safety. This article retrieves relevant research literature published domestically and internationally regarding the regulation of the PI3K/Akt/mTOR signaling pathway by TCM in the treatment of CRC and conducts detailed classification and summary. The active components of TCM include glycosides， flavonoids， alkaloids， terpenoids， polyphenols， and naphthoquinones. The volatile oils and extracts of TCM include Angelicae Sinensis Radix volatile oil， Astragali Radix polysaccharides， Caryophylli Flos extract， Forsythiae Fructus extract， Curcumae Longae Rhizoma extract， and Celastrus orbiculatus extract. The compound formulas of TCM include Banxia Xiexin decoction， Jianpi Qingre Huoxue formula， and Chanling Plaster. Through summary and analysis， it is discovered that the abovementioned TCM can produce effects such as blocking the cell cycle， inducing autophagy and apoptosis， inhibiting angiogenesis， suppressing proliferation and migration， and reversing chemotherapy resistance and radiotherapy resistance by inhibiting the PI3K/Akt/mTOR pathway in CRC cells. TCM holds promise in the research and application of targeting the PI3K/Akt/mTOR signaling pathway for CRC treatment. The summary and conclusion of this article aim to provide references for subsequent research and the development of new drugs.关键词：colorectal cancer;traditional Chinese medicine;PI3K/Akt/mTOR signaling pathway;mechanism of action;research progress110|104|0更新时间：2025-10-09

- “据最新研究，中医药调控AMPK信号通路治疗肺癌，有望提供更高效、安全的新疗法。”摘要：As a common malignant tumor of the respiratory system， the incidence and mortality of lung cancer are still rising year by year. Its pathogenesis is complex， the prognosis is poor， and it seriously affects human physical and mental health. Although existing Western medical treatments can inhibit tumor growth to a certain extent and relieve patients' painful symptoms， problems such as postoperative recurrence and metastasis， numerous adverse reactions， and the tendency to develop drug resistance make the overall therapeutic effect unsatisfactory. Therefore， it is urgent to seek more efficient and safer treatments. Adenosine monophosphate-activated protein kinase （AMPK） signaling pathway can regulate the growth， differentiation， apoptosis， and autophagy of lung cancer cells， and is extensively involved in the occurrence and development of lung cancer， thus being regarded as an important target for anti-lung cancer therapy. Traditional Chinese medicine （TCM） exerts anti-lung cancer effects through multiple pathways， mechanisms， and targets， with advantages such as preventing postoperative recurrence and metastasis， alleviating the adverse reactions of radiotherapy and chemotherapy， and improving quality of life. TCM has therefore become a key approach in current anti-lung cancer treatment. Studies have found that active components of Chinese medicine， including flavonoids， saponins， polyphenols， and terpenes， as well as Chinese medicine compound prescriptions such as Guiqi Yiyuan extract， Qingzao Jiufei decoction， and Yiqi Fuzheng formula， have significant regulatory effects on AMPK and its interacting signaling pathways. These effects include inducing autophagy and apoptosis of lung cancer cells， modulating macrophage polarization， inhibiting epithelial-mesenchymal transition， reversing drug resistance， and blocking the cell cycle， thereby exerting anti-lung cancer activity. This article reviews and summarizes recent studies on the anti-lung cancer effects of TCM， and discusses the mechanisms by which TCM regulates the AMPK signaling pathway in the treatment of lung cancer， with the aim of providing ideas and references for the development of new clinical anti-lung cancer drugs.关键词：adenosine monophosphate-activated protein kinase （AMPK）;signaling pathway;traditional Chinese medicine;lung cancer;research progress132|170|0更新时间：2025-10-09
