Effect of Buzhong Yiqitang on Th17/Treg Immune Imbalance and Notch1 Signaling Pathway in AIT Mice AI导读
摘要：ObjectiveTo explore the effect of Buzhong Yiqitang on the immune imbalance of helper T cell 17 （Th17）/regulatory T cell （Treg） and Notch1 signaling pathway in mice with autoimmune thyroiditis （AIT）.MethodA total of 60 8-week-old NOD.H-2h4 mice were randomly divided into the normal group， model group， western medicine group （selenium yeast tablet， 32.5 mg·kg-1）， and low-dose （4.78 g·kg-1·d-1）， middle-dose （9.56 g·kg-1·d-1）， and high-dose （19 g·kg-1·d-1） Buzhong Yiqitang groups， with 10 mice in each group. The normal group was fed with distilled water， and the other groups were fed with water containing 0.05% sodium iodide for eight weeks. After the animal model of AIT was formed spontaneously， the mice were killed under anesthesia after intragastric administration for eight weeks. Serum anti-thyroglobulin antibodies （TGAb）， thyroid-stimulating hormone （TSH）， free triiodothyronine （FT3）， and free thyroid hormone （FT4） were detected by enzyme-linked immunosorbent assay （ELISA）， and thyroid tissue changes were observed by hematoxylin-eosin （HE） staining. The mRNA and protein expressions of retinoid-related orphan receptor-γt （RORγt）， interleukin （IL）-17， forkhead box P3 （FoxP3）， IL-10， Notch1， and hair division-related enhancer 1 （Hes1） in thyroid tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively.ResultCompared with the normal group， the thyroid structure of the model group was severely damaged， and lymphocytes were infiltrated obviously. The levels of serum TGAb， FT3， and FT4 contents were significantly increased， and TSH content was significantly decreased （P<0.01）. The mRNA and protein expression levels of RORγt， IL-17， Notch1， and Hes1 were significantly increased， while those of FoxP3 and IL10 were significantly decreased in the model group （P<0.01）. Compared with the model group， thyroid structural damage and lymphocyte infiltration were improved in the treatment groups， and serum TGAb， FT3， and FT4 contents were significantly decreased. TSH content was increased， and mRNA and protein expression levels of RORγt， IL-17， Notch1， and Hes1 were decreased. mRNA and protein expression levels of FoxP3 and IL-10 were increased to different degrees （P<0.05， P<0.01）， and the middle-dose Buzhong Yiqitang group had the most significant intervention effect.ConclusionBuzhong Yiqitang can alleviate the thyroid structural damage in AIT mice， and its mechanism may be related to improving the abnormal differentiation of Th17/Treg immune cells and inhibiting the activation of the Notch1 signaling pathway.关键词：Buzhong Yiqitang;autoimmune thyroiditis;helper T cell 17 （Th17）/regulatory T cell （Treg）;Notch1 signaling pathway;inflammation- 132

The contents of active ingredients in Erdongtang was detected by electrospray ionization（ESI） and multiple reaction monitoring（MRM） mode under positive and negative ion modes. On this basis， network pharmacology was applied to predict the targets and pathways of Erdongtang exerting anti-insulin resistance effect.ResultThe 20 active ingredients in Erdongtang showed good linear relationships within a certain mass concentration range， and the precision， stability， repeatability and recovery rate were good. The results of determination showed that the ingredients with high content in 15 batches of samples were baicalein（1 259.39-1 635.78 mg·L-1）， baicalin（1 078.37-1 411.52 mg·L-1）， the ingredients with medium content were mangiferin（148.59-217.04 mg·L-1）， timosaponin BⅡ（245.10-604.89 mg·L-1）， quercetin-3-O-glucuronide（89.30-423.26 mg·L-1）， rutin（46.91-1 553.61 mg·L-1）， glycyrrhizic acid（55.97-391.47 mg·L-1）， neomangiferin（37.45-127.03 mg·L-1）， nuciferine（0.89-63.48 mg·L-1）， hyperoside（6.96-136.78 mg·L-1）， liquiritin（30.89-122.78 mg·L-1）， liquiritigenin（26.64-110.67 mg·L-1）， protodioscin（58.57-284.26 mg·L-1）， the ingredients with low content were wogonin（7.16-20.74 mg·L-1）， pseudoprotodioscin（5.49-22.96 mg·L-1）， ginsenoside Rb1（7.31-23.87 mg·L-1）， ginsenoside Rg1（10.78-28.33 mg·L-1）， ginsenoside Re（7.78-24.76 mg·L-1）， ophiopogonin D（2.08-4.29 mg·L-1）， methylophiopogonanone A（0.74-1.67 mg·L-1）. The results of network pharmacology indicated that the mechanism of anti-insulin resistance exerted by Erdongtang might be related to the phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway.ConclusionThe established UHPLC-QqQ-MS has the advantages of simple sample processing， strong exclusivity and high sensitivity， and can simultaneously determine the contents of the main ingredients from seven herbs in Erdongtang， which can lay the foundation for the development of Erdongtang compound preparations. The results of the network pharmacology can provide a reference for the mechanism study of Erdongtang in the treatment of type 2 diabetes mellitus.关键词：famous classical formulas;Erdongtang;active ingredients;quantitative analysis;network pharmacology;type 2 diabetes mellitus;ultra-high performance liquid chromatography-tandem triple quadrupole mass spectrometry（UHPLC-QqQ-MS）

发布时间：2024-02-28 - 摘要：ObjectiveTo investigate the mechanism of Baihuan Xiaoyao Decoction （Xiaoyaosan added with Lilii Bulbus and Albiziae Cortex） in alleviating depression-like behaviors of juvenile rats by regulating the polarization of microglia.MethodSixty juvenile SD rats were randomized into normal control， model， fluoxetine， and low-， medium-， and high-dose （5.36， 10.71， 21.42 g·kg-1， respectively） Baihuan Xiaoyao decoction groups. The rat model of juvenile depression was established by chronic unpredictable mild stress （CUMS）. The sucrose preference test （SPT） was carried out to examine the sucrose preference of rats. Forced swimming test （FST） was carried out to measure the immobility time of rats. The open field test （OFT） was conducted to measure the total distance， the central distance， the number of horizontal crossings， and the frequency of rearing. Morris water maze （MWM） was used to measure the escape latency and the number of crossing the platform. The immunofluorescence assay was employed to detect the expression of inducible nitric oxide synthase （iNOS， the polarization marker of M1 microglia） and CD206 （the polarization marker of M2 microglia）. Real-time polymerase chain reaction was employed to determine the mRNA levels of iNOS， CD206， pro-inflammatory cytokines ［tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and IL-6］ and anti-inflammatory cytokines （IL-4 and IL-10） in the hippocampus. Western blotting was employed to determine the protein levels of iNOS and CD206 in the hippocampus. The levels of IL-4 and IL-6 in the hippocampus were detected by enzyme-linked immunosorbent assay.ResultCompared with the normal control group， the model rats showed a reduction in sucrose preference （P<0.05）， an increase in immobility time （P<0.05）， decreased motor and exploratory behaviors （P<0.05）， and weakened learning and spatial memory （P<0.05）. In addition， the model rats showed up-regulated mRNA and protein levels of iNOS and mRNA levels of IL-1β， IL-6， and TNF-α （P<0.05）. Compared with the model group， Baihuan Xiaoyao decoction increased the sucrose preference value （P<0.05）， shortened the immobility time （P<0.01）， increased the motor and exploratory behaviors （P<0.05）， and improved the learning and spatial memory （P<0.01）. Furthermore， the decoction down-regulated the positive expression and protein level of iNOS， lowered the levels of TNF-α， IL-1β， and IL-6 （P<0.01）， promoted the positive expression of CD206， and elevated the levels of IL-4 and IL-10 （P<0.01） in the hippocampus of the high dose group. Moreover， the high-dose Baihuan Xiaoyao decoction group had higher sucrose preference value （P<0.01）， shorter immobility time （P<0.01）， longer central distance （P<0.01）， stronger learning and spatial memory （P<0.01）， higher positive expression and protein level of iNOS （P<0.01）， lower levels of TNF-α， IL-1β， and IL-6 （P<0.05， P<0.01）， lower positive expression and mRNA level of iNOS （P<0.05）， and higher levels of IL-4 and IL-10 （P<0.05， P<0.01） than the fluoxetine group.ConclusionBaihuan Xiaoyao decoction can improve the depression-like behavior of juvenile rats by inhibiting the M1 polarization and promoting the M2 polarization of microglia in the hippocampus.关键词：juvenile depression;chronic unpredictable mild stress （CUMS）;hippocampus;polarization of microglia;Baihuan Xiaoyao decoction

发布时间：2024-02-28 - 摘要：ObjectiveTo observe the effects of the South African herb Hoodia gordonii （HG） on glucolipid metabolism in diabetic db/db mice and explore the possible mechanisms of HG on the liver of db/db mice based on the phosphoinositide-3 kinase （PI3K）/protein kinase B （Akt）/factor forkhead protein O1 （FoxO1） signaling pathway.MethodA total of 30 db/db mice were randomly divided into five groups according to fasting blood glucose： model group， metformin group （0.195 g·kg-1）， and low dose （0.39 g·kg-1）， medium dose （0.78 g·kg-1）， and high dose （1.56 g·kg-1） HG groups， with six m/m mice in each group， and another six m/m mice were set as normal group. The mice in the normal and model groups were given saline of 9 mL·kg-1 by gavage. Body weight， water intake， and fasting blood glucose of the mice in each group were measured weekly. After six weeks of continuous administration， serum insulin （FINS）， low-density lipoprotein cholesterol （LDL）， total cholesterol （TC）， triglyceride （TG）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine （CREA） were measured， and liver sections were embedded and stained with hematoxylin-eosin （HE）， periodic acid-Schiff （PAS）， and oil red O. Protein expression of PI3K p85， p-Akt， and p-FoxO1 in liver was detected by immunohistochemistry. The mRNA expression of PI3K， Akt， and FoxO1 in liver tissue was detected by real-time polymerase chain reaction （Real-time PCR）.ResultAfter six weeks of administration intervention， it was found that fasting blood glucose was significantly downregulated in mice in the three HG groups （P<0.05）. The level of islet resistance index was significantly reduced in both the low and medium dose HG groups （P<0.05）. The expression levels of TC， TG， and LDL were reduced in all HG groups （P<0.05， P<0.01）. Pathologically， HG could alleviate hepatocyte steatosis， reduce the volume and content of lipid droplets in liver， and increase the distribution of glycogen granules in liver to some extent in mice. Immunohistochemical assays revealed that PI3K p85 protein expression was significantly increased in the low， medium， and high dose HG groups compared with the model group （P<0.01）. p-Akt protein expression was significantly increased in the medium and high dose HG groups （P<0.05， P<0.01）. p-FoxO1 protein expression was significantly increased in the low， medium， and high dose HG groups （P<0.05， P<0.01）. Compared with the model group， PI3K mRNA was increased in low dose， medium dose， and high dose HG groups （P<0.05）， and Akt mRNA was increased in high dose HG group （P<0.05）. FoxO1 mRNA was decreased in low dose， medium dose， and high dose HG groups （P<0.05）.ConclusionHG can ameliorate the disorder of glucolipid metabolism in db/db mice， which may be related to its activation of the hepatic PI3K/Akt/FoxO1 signaling pathway.关键词：Hoodia gordonii;diabetes mellitus;db/db mice;phosphoinositide-3 kinase/protein kinase B/homo sapiens forkhead box O1 （PI3K/Akt/FoxO1） signaling pathway

The cells were classified into normal （5.5 mmol·L-1 glucose+10% blank serum）， model （30 mmol·L-1 glucose+10% blank serum）， DMix-containing serum （30 mmol·L-1 glucose+10% DMix-containing serum）， ferroptosis inhibitor （Fer-1， 30 mmol·L-1 glucose+10% blank serum+1 μmol·L-1 Fer-1） groups. The corresponding kits were used to measure the levels of Fe2+ and lactate dehydrogenase （LDH） in cells. Enzyme-linked immunosorbent assay was employed to determine the content of glutathione （GSH） and lipid peroxide （LPO） in cells. Fluorescence probe was used to measure the reactive oxygen species （ROS） level. Real-time fluorescence quantitative polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels， respectively， of Wilms' tumor-1 （WT-1）， desmin， long chain acyl-CoA synthase 4 （ACSL4）， and glutathione peroxidase 4 （GPX4） in podocytes.ResultCompared with the blank group， the intervention with 30 mmol·L-1 glucose for 48 h reduced podocyte viability （P<0.01）， and the 10% DMix-containing serum showed the most significant improvement in podocyte viability （P<0.01）. Compared with the normal group， the model group presented elevated levels of Fe2+， LDH， LPO， and ROS， lowered GSH level， up-regulated mRNA and protein levels of desmin and ACSL4， and down-regulated mRNA and protein levels of WT-1 and GPX4 （P<0.01）. Compared with the model group， the DMix-containing serum lowered the Fe2+， LDH， LPO， and ROS levels， elevated the GSH level， down-regulated the mRNA and protein levels of desmin and ACSL4， and up-regulated the mRNA and protein levels of WT-1 and GPX4 in podocytes （P<0.05， P<0.01）.ConclusionDMix-containing serum exerts a protective effect on high glucose-induced podocyte injury by inhibiting ferroptosis.关键词：Dendrobium mixture;diabetic nephropathy;podocyte;ferroptosis- 60

发布时间：2024-02-28 - 摘要：ObjectiveTo study the mechanism of astragaloside Ⅳ （AS Ⅳ） on db/db mice with type 2 diabetes mellitus （T2DM） and non-alcoholic fatty liver disease （NAFLD） based on network pharmacology and experimental validation.MethodA total of 24 db/db mice were randomly divided into four groups： model group， metformin group， and low-dose and high-dose AS Ⅳ groups. Six C57 mice were used as the blank group. The low-dose and high-dose AS Ⅳ groups were given AS Ⅳ of 0.015 and 0.030 g·kg-1 by gavage， and the metformin group was given 0.067 g·kg-1 by gavage. The blank and model groups were given equal volumes of distilled water by gavage. After intragastric administration， fasting blood glucose （FBG） was detected， and an oral glucose tolerance test was performed. Serum lipid level and liver histopathology were detected. The target and enrichment pathway of AS Ⅳ for treating T2DM and NAFLD were predicted by network pharmacology， and the main enrichment pathway was verified by molecular biology techniques. The protein expressions of AMPK， p-AMPK， sterol regulatory element-binding protein-1 （SREBP-1）， and fatty acid synthetase （FAS） in liver tissue were detected by Western blot.ResultCompared with the blank group， the levels of body mass， liver weight coefficient， fasting blood glucose， serum total cholesterol， triglyceride， and low-density lipoprotein cholesterol in mice treated with AS Ⅳ were decreased （P<0.05， P<0.01）. The pathology of liver tissue showed significant improvement in lipid accumulation， and imaging results showed that the degree of fatty liver was reduced after AS Ⅳ therapy. Network pharmacological prediction results showed that vascular endothelial growth factor α （VEGFA）， galactoagglutinin 3 （LGALS3）， serine/threonine kinase B2 （Akt2）， RHO-associated coiled-coil protein kinase 1 （ROCK1）， serine/threonine kinase B1 （Akt1）， signaling and transcriptional activator protein （STAT3）， and messtimal epidermal transformation factor （MET） were key targets in "drug-disease" network. The results from the Kyoto encyclopedia of genes and genomes （KEGG） enrichment showed that the AMP-dependent protein kinase （AMPK） signaling pathway was strongly associated with T2DM and NAFLD. Western blot results showed that compared with the blank group， the expression levels of p-AMPK/AMPK in the model group were significantly down-regulated， while those of SREBP-1 and FAS proteins were significantly up-regulated （P<0.01）. Compared with the model group， the expression levels of p-AMPK/AMPK in the metformin group and high-dose AS Ⅳ group were significantly up-regulated， while those of SREBP-1 and FAS proteins were significantly down-regulated （P<0.05， P<0.01）.ConclusionAS Ⅳ regulates the expression of lipid proteins by activating the AMPK signaling pathway， thereby improving lipid metabolism.关键词：astragaloside Ⅳ;type 2 diabetes;non-alcoholic fatty liver disease;db/db mouse;network pharmacology

发布时间：2024-02-28 - 摘要：ObjectiveThe antitumor activity of sesquiterpenoid M36 isolated from Myrrha against human hepatoma HepG2 cells was investigated in this study.MethodHepG2 cells were treated with M36 at different concentrations （0， 2， 4， 6， 8， 10 μmol·L-1）. Firstly， the effects of M36 on the proliferation of human hepatoma HepG2 cells were detected by methyl thiazolyl tetrazolium （MTT）， colony formation assay， and EdU proliferation assay. Hoechst staining， flow cytometry analysis， and Western blot were used to explore the effect of M36 on the apoptosis of human hepatoma HepG2 cells. Acridine orange staining and western blotting were used to examine the effect of M36 on autophagy in HepG2 cells. Finally， Western blot was used to detect protein expression of cancer-related signaling pathways.ResultCompared with the blank group， M36 treatment significantly inhibited the proliferation of human hepatoma HepG2 cells （P<0.01）， and the half inhibitory concentration （IC50） value of M36 for 48 h was 5.03 μmol·L-1， in a dose- and time-dependent manner. M36 was also able to induce apoptosis and autophagy in human hepatoma HepG2 cells. After treatment with 8 μmol·L-1 M36 for 48 hours， the apoptosis rate of HepG2 cells was （42.03±9.65）% （P<0.01）. Compared with the blank group， HepG2 cells treated with 4 and 8 μmol·L-1 M36 for 48 h had a significant increase in cleaved poly ADP-ribose polymerase （cleaved-PARP） protein levels （P<0.01）. Acridine orange staining showed that autophagy was significantly activated in HepG2 cells treated with 4 and 8 μmol·L-1 M36 for 48 h compared with the blank group （P<0.01）， which was further verified by the up-regulation of microtubule-associated protein 1 light chain 3 Ⅱ （LC3 Ⅱ）. Western blot results showed that compared with the blank group， the levels of phosphorylated extracellular regulated protein kinase （p-ERK）， phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）， phosphorylated c-Jun N-terminal kinase （p-JNK）， and its downstream nuclear transcription factors c-Jun and p-c-Jun protein were significantly increased in M36 group （P<0.05， P<0.01）. The mechanism may be related to the up-regulation of MAPK signaling pathway.ConclusionThe sesquiterpenoid M36 isolated from Myrrha inhibits the proliferation of human hepatoma HepG2 cells and promotes apoptosis and autophagy， which may be related to the activation of the MAPK signaling pathway.关键词：Myrrha;sesquiterpenoid M36;human hepatoma HepG2 cells;apoptosis;autophagy;mitogen-activated protein kinase （MAPK） signaling pathway

发布时间：2024-02-28 - 摘要：ObjectiveThis study observes the intervention effect of Longmu Piyan prescription on oxidative stress in BALB/c mice with atopic dermatitis （AD） induced by 2，4-dinitrochlorobenzene （DNCB） and explores its mechanism.MethodThe AD model was established using the method of DNCB sensitization on the back skin of BALB/c mice. Forty male BALB/c mice were randomly divided into a blank group， a model group， a vitamin C control group （0.5×10-3 mg·kg-1）， and a Longmu Piyan prescription group （26 g·kg-1）. Except for the blank group， other groups were sensitized with different concentrations of DNCB on the back to induce AD， and the blank group was treated with matrix coating. The gastric administration was started on the seventh day after sensitization with 2% DNCB and on the 24th day after sensitization with 0.2% DNCB continuously for 21 days. The changes in skin lesions of each group were directly observed after the experiment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of interleukin （IL）-4， tumor necrosis factor （TNF）-α， immunoglobulin E （IgE）， and reactive oxygen species （ROS） in the serum of each group. The total antioxidant capacity determination kit-trace method (ABTS method) was used to measure the level of total antioxidant capacity （TAOC） in serum. The Hematoxylin eosin （HE） staining method was used to observe the pathological and morphological changes of the skin lesion site. The immunohistochemical method was used to detect the expression of thymic stromal lymphopoietin （TSLP） in the skin lesion site. Western blot was used to detect the expression of filaggrin （FLG） in the dorsal skin lesions.ResultThe results showed that compared with the blank group， the skin lesion score of the model group mice was significantly increased （P<0.01）， and HE staining showed characteristic pathological changes of AD in the skin lesion site. At the same time， the expression of TSLP in the skin lesion was significantly increased， and that of FLG was reduced （P<0.05）. The levels of TNF-α， IL-4， IgE， and ROS in serum increased， while the activity of TAOC decreased （P<0.01）. Compared with the model group， the Longmu Piyan prescription group showed a significant decrease in skin lesion scores and a significant improvement in skin lesion pathology. At the same time， the expression of TSLP decreased， and the expression of FLG increased in the skin lesions （P<0.05）. In addition， compared with the model group， the serum levels of TNF-α， IL-4， IgE， and ROS also decreased to varying degrees （P<0.05，P<0.01）， and TAOC activity increased in the Longmu Piyan prescription group （P<0.01）.ConclusionThere is a significant correlation among the degree of oxidative stress， the severity of skin lesions in AD， and the levels of inflammatory cytokines. Longmu Piyandu prescription can improve AD-like skin lesions in BALB/c mice by promoting ROS clearance， enhancing TAOC， and inhibiting oxidative stress， thus protecting the skin barrier and reducing inflammation.关键词：atopic dermatitis;Longmu Piyan prescription;oxidative stress;experimental study;mechanism

发布时间：2024-02-28 - 摘要：Trials within cohorts （TwiCs） are design methods derived from randomized controlled trials （RCTS）. They have been widely used in chronic disease areas such as tumors and cardiovascular diseases. The basis of the TwiCs design is a prospective cohort of specific diseases. When RCTS need to be implemented， some patients meeting the inclusion and exclusion criteria are randomly sampled from the cohort to receive "trial interventions"， while the remaining patients in the cohort who meet the inclusion and exclusion criteria continue to receive conventional treatment as control groups. By comparing the efficacy differences between the intervention measures of the trial group and the control group， the efficacy of intervention measures was evaluated. Within the cohort， the same process could be repeated to carry out multiple RCTS， so as to evaluate different intervention measures or compare the efficacy of different doses or timing of interventions. Compared with classical RCTS， TwiCs make it easier to recruit patients from the cohort and have higher external validity， providing a new research paradigm for improving the efficiency and applicability of RCTS in clinical practice. However， TwiCs may also face the challenge of poor compliance of patients in the cohort. Researchers need to take effective measures to control these patients in the design and operation of TwiCs. This article focused on the methodological key points during the implementation of TwiCs， including multi-stage informed consent （patients are informed of consent at three stages： entering the cohort， entering the trial group， and after the trial）， randomization procedures （only random sampling of patients from the cohort to receive "trial interventions"）， sample size calculation， and statistical analysis methods. The article also compared the differences between TwiCs and traditional RCTS and illustrated TwiCs research design and analysis with examples， so as to provide new research ideas and methods for clinical researchers.关键词：trials within cohorts;multiple randomized controlled trials within cohort;patient cohort;random sampling;multi-stage informed consent

发布时间：2024-02-28 - 摘要：ObjectiveTo explore the application effect of Jianpi Huoxue prescription combined with acupuncture in patients with chronic atrophic gastritis （CAG） of gastric blood stasis type.MethodA total of 86 patients with CAG admitted to Wuhan First Hospital from November 2021 to March 2023 were selected and randomly divided into two groups. The control group was treated with conventional Western medicine， while the observation group was treated with Jianpi Huoxue prescription combined with acupuncture. The clinical efficacy， traditional Chinese medicine （TCM） syndrome score， pathological score， negative conversion rate of Helicobacter pylori （Hp）， inflammatory indicators ［neutrophils/lymphocytes （NLR） and interleukin （IL）-1β］， changes in levels of gastric protease （PG） Ⅰ， PG Ⅰ/PG Ⅱ， and gastrin-17 （G-17）， and drug safety during treatment were observed after treatment in both groups.ResultAfter treatment， the total effective rate of the observation group ［95.35% （41/43）］ was significantly better than that of the control group ［79.07% （34/43）］， and the difference was statistically significant （χ2=5.108， P<0.05）. After treatment， the scores of the primary and secondary TCM syndromes in the observation group and the control group were significantly decreased （P<0.05）. After treatment， the scores of primary and secondary TCM syndromes in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia were significantly lower in the observation group and control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the Hp conversion rate in the observation group was significantly increased compared with the control group （P<0.05）. After treatment， the levels of inflammatory indicators NLR and IL-1β in the observation group and control group were significantly lower （P<0.05）， and the levels of inflammatory indicators NLR and IL-1β in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the levels of PGI and PGⅠ/PGⅡ in the observation group and control group were significantly higher （P<0.05）， and the levels of PGI and PGⅠ/PGⅡ in the observation group were significantly higher than those in the control group （P<0.05）. After treatment， the G-17 level of the observation group and the control group was different at different time points （P<0.05）， and the G-17 level of the observation group was higher at different time points than that of the control group （P<0.05）. The G-17 level of the observation group had an increasing trend compared with the control group （P<0.05）. There was no significant difference in the risk of adverse reactions between the two groups.ConclusionThe combination of Jianpi Huoxue prescription and acupuncture can effectively alleviate symptoms， increase Hp negative conversion rate， inhibit inflammation， and regulate PG and G-17 levels in CAG patients， thus controlling or even reversing gastric mucosal atrophy and reducing the probability of its progression to gastric cancer.关键词：chronic atrophic gastritis;gastric blood stasis;Jianpi Huoxue prescription;acupuncture;clinical effects

发布时间：2024-02-28 - 摘要：ObjectiveTo systematically evaluate the distribution of traditional Chinese medicine（TCM） syndromes of primary osteoporosis（POP） in China by using evidence-based medicine methods， and to understand the distribution law of the syndromes.MethodChina National Knowledge Infrastructure（CNKI）， VIP Chinese Science and Technology Journal Database（VIP）， WanFang Data Knowledge Service Platform（WanFang） and China Biology Medicine（CBM） were searched to obtain representative literature， and each database was searched from the 1994 World Health Organization defined diagnostic criteria for osteoporosis until May 1， 2023. Two researchers independently screened literature according to the criteria， extracted data， and cross-checked them. Meta analysis was conducted using R4.1.3， and subgroup analysis was performed.ResultA total of 56 Chinese papers were included， involving 14 415 patients. After standardized classification of syndromes， 11 articles were excluded， and Meta analysis results of the ultimately included 45 Chinese articles showed that the distribution frequencies of liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome in 12 723 patients were 27%［95% confidence interval（CI） 0.24-0.31］， 32%（95% CI 0.29-0.36）， 36%（95% CI 0.30-0.42）. Subgroup analysis showed that there was a statistically significant difference in the distribution of the three TCM syndromes in the north and south（P<0.05）. In addition， the incidence of TCM syndrome fractures in different types of POP was 15%（95% CI 0.09-0.24） for liver-kidney Yin deficiency syndrome， 20%（95% CI 0.12-0.30） for spleen-kidney Yang deficiency syndrome， and 31%（95% CI 0.25-0.39） for kidney deficiency and blood stasis syndrome.ConclusionThe distribution of syndromes in POP patients is mainly kidney deficiency， accompanied by liver and spleen dysfunction. Liver-kidney Yin deficiency syndrome， spleen-kidney Yang deficiency syndrome and kidney deficiency and blood stasis syndrome are all the main syndromes of POP and osteoporotic fractures， and kidney deficiency and blood stasis syndrome is most closely related to the development of osteoporotic fractures. The reference standards for syndrome determination among the included studies are inconsistent， and in the future， it is necessary to focus on their determination standards to obtain consensus research results， at the same time， conduct large-scale syndrome research to obtain representative research results， providing a basis for clinical practice and research.关键词：primary osteoporosis（POP）;traditional Chinese medicine syndrome;systematic review;Meta analysis;cross-sectional study;evidence-based medicine approach;fracture

The model group was given thyroid tablet suspension（0.003 2 g·kg-1） by gavage for 14 consecutive days， and 10% CCl4（5 mL·kg-1） was intraperitoneally injected once a week to establish a liver Yin deficiency model， while the blank group was injected with an equal amount of olive oil intraperitoneally and gavaged with an equal amount of distilled water， and was fed with normal feed. After the modeling was completed， 6 mice in each group were randomly selected， the levels of alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， cyclic adenosine monophosphate（cAMP）， cyclic guanosine monophosphate（cGMP）， interleukin（IL）-6， IL-10， tumor necrosis factor-α（TNF-α）were measured in the mice serum， and malondialdehyde（MDA）， superoxide dismutase（SOD）， total protein（TP）， hydroxyproline（HYP） and other indicators were measured in the mice liver. Liver tissue sections were taken for hematoxylin-eosin（HE） staining and observing pathological changes. The remaining 6 mice in each group were subjected to UPLC-Q-TOF-MS combined with principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were used to screen differential metabolites in the liver Yin deficiency mouse model， Kyoto Encyclopedia of Genes and Genomes（KEGG） database was used to analyze the corresponding metabolic pathways of differential metabolites.ResultCompared with the blank group， mice in the model group showed liver Yin deficiency manifestations such as reduced body weight， fatigue and sleepiness， disheveled and lusterless hair， irritability. The levels of ALT， cAMP/cGMP， IL-6， AST， MDA， cAMP， TNF-α significantly increased（P<0.05， P<0.01）， while the levels of SOD， IL-10 and cGMP significantly decreased（P<0.05， P<0.01）， and the changes of HYP and TP were not statistically significant. Hepatic steatosis and distortion of the radial arrangement of the liver plate cells were seen in the section images of the model group， endogenous substances were clearly separated， and 252 differential metabolites were identified in the serum samples， which were mainly involved in the metabolic pathways of purine metabolism， steroid hormone biosynthesis and pyrimidine metabolism. A total of 229 differential metabolites were identified in the liver samples， mainly involving nucleotide metabolism， purine metabolism， steroid hormone biosynthesis， pyrimidine metabolism， antifolate resistance， insulin resistance， primary bile acid biosynthesis， prostate cancer， sulfur relay system， arachidonic acid metabolism and other metabolic pathways.ConclusionThe successful establishment of liver Yin deficiency model in mice by CCl4 combined with thyroid hormone is evaluated through the investigation of serum and liver metabolomics， combined with biochemical indicators， which provides a biological basis and experimental foundation for the Yin deficiency syndrome model of TCM.关键词：liver Yin deficiency;metabolomics;traditional Chinese medicine syndrome;model evaluation;metabolic pathway;ultra performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry（UPLC-Q-TOF-MS）

The contents of eight representative components of ABR were measured by high performance liquid chromatography（HPLC）， the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis， and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis， and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing， and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural， polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone， ginsenoside Ro， chikusetsusaponin Ⅳa and polysaccharides as variables， the discriminant function was established respectively， and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function.ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters， and the results could significantly distinguish different processed products. During the process of wine and salt processing， the contents of 5-hydroxymethylfurfural， ginsenoside Ro， and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree， while the contents of polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone and polysaccharides showed a gradual decreasing trend， indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value（L*） and the total color difference value（E*ab）（P<0.01）， and positively correlated with the red-green value（a*） and the yellow-blue value（b*）（P<0.01）， and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab（P<0.01）. The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis， and their accuracy rates in the training samples were 93.75% and 95.83%， respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution， and the correct rate was 100%.ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent， and the color value can better distinguish ABR with different processing degrees， and the color of ABR is related to some representative components in the processing process， indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.关键词：Achyranthis Bidentatae Radix;processing of traditional Chinese medicine;producing area;high performance liquid chromatography（HPLC）;content determination;quality evaluation;color-component correlation analysis

发布时间：2024-02-28 - 摘要：ObjectiveThe angiosperm phylogeny group （APG） Ⅳ system is currently the latest angiosperm classification system. The APG system based on DNA sequence can more naturally reflect the phylogeny and evolution of plants， which has been widely recognized and applied in scientific research and teaching of plants in other countries. Through the comparison between the changes in the APG Ⅳ system and the traditional plant classification system， the changes in the taxonomic status of the original plants of traditional Chinese medicine （TCM） in the 2020 edition of Chinese Pharmacopoeia were reviewed.MethodBy referring to the literature in China and abroad， the changes in the taxonomic status of the original plants of TCM recorded in Chinese Pharmacopoeia were sorted out according to the basic groups of angiosperms in the APG Ⅳ system， including the basal group of ANA， the magnoliid and chloranthales， the basal groups of monocots and eudicots， the superrosids， and the superasterids.ResultThere are about 72 species of TCM in the 2020 edition of Chinese Pharmacopoeia. A total of 76 species of the original plants change in family grade according to the APG Ⅳ system. There are 22 species of TCM belonging to the dicotyledon class， involving 26 species of the original plants. It should be placed in front of the differentiation of monocotyledons and eudicotyledons according to the APG Ⅳ system.ConclusionThis paper largely clarifies the change in the taxonomic status of the original plants of TCM in Chinese Pharmacopoeia according to the APG Ⅳ system， which is helpful to the reviewing literature in China and abroad for the original plants of TCM and facilitates the international academic exchange for TCM. It provides a reference for the revision of textbooks such as Botany and Medicinal Botany in Chinese colleges and universities and will lay the foundation for updating the content of Chinese Pharmacopoeia in the future.关键词：APG Ⅳ;traditonal Chinese medicine;angiosperms;Chinese Pharmacopoeia;Flora of China;original plants;taxonomic status

Currently， there are still some unclear causes of oligoasthenozoospermia in clinical practice， known as idiopathic oligoasthenozoospermia. With the development of high-throughput sequencing technology， it has been found that intestinal microbiota disorder may be an important promoting factor for the onset of oligoasthenozoospermia. Traditional Chinese medicine believes that "deficiency of kidney essence" is the core pathogenesis of oligoasthenozoospermia. In clinical practice， the method of tonifying the kidney and strengthening the essence has a significant therapeutic effect on oligoasthenozoospermia， but its mechanism of action has not been fully elucidated. Based on the basic theories of traditional Chinese medicine and molecular biology research， it has been found that there is a similarity between "kidney essence" and intestinal microbiota. During the onset of oligoasthenozoospermia， the disorder of intestinal microbiota has similarities with the pathogenesis of "deficiency of kidney essence" in traditional Chinese medicine. Moreover， traditional Chinese medicine for tonifying the kidney and strengthening the essence can regulate the disorder of intestinal microbiota， which may be one of the effective mechanisms for the treatment of oligoasthenozoospermia with the Bushen Yijing method. Based on this， this article explored the mechanism of Bushen Yijing method of traditional Chinese medicine in treating oligoasthenozoospermia from the perspective of intestinal microbiota， so as to provide new ideas for the treatment of oligoasthenozoospermia with traditional Chinese medicine.关键词：oligoasthenozoospermia;intestinal microbiota;deficiency of kidney essence;tonifying the kidney and strengthening the essence;traditional Chinese medicine

发布时间：2024-02-28 - 摘要：In order to promote the innovative application of Sanjiao theory and Yingwei theory， this paper tries to apply the ''Sanjiao-Yingwei'' Qi transformation theory to the treatment of tumor diseases， integrating it with T cell exhaustion mechanism to elaborate on its scientific connotation and using network pharmacology and bioinformatics to elucidate the correlation between the anti-tumor mechanism of ''Sanjiao-Yingwei'' Qi transformation and T cell exhaustion. The ''Sanjiao-Yingwei'' Qi transformation function is closely related to the immunometabolic ability of the human body， and the ''Sanjiao-Yingwei'' Qi transformation system constitutes the immunometabolic exchange system within and outside the cellular environment. Cancer toxicity is generated by the fuzzy Sanjiao Qi， and the long-term fuzzy Sanjiao Qi is the primary factor leading to T cell exhaustion， which is related to the long-term activation of T cell receptors by the high tumor antigen load in the tumor microenvironment. Qi transformation malfunction of the Sanjiao produces phlegm and collects stasis， which contributes to T cell exhaustion and is correlated with nutrient deprivation， lipid accumulation， and high lactate levels in the immunosuppressed tumor microenvironment， as well as with the release of transforming growth factor-β and upregulated expression of programmed death receptor-1 by tumor-associated fibroblasts and platelets in the tumor microenvironment. Ying and Wei damage due to Sanjiao Qi transformation malfunction is similar to the abnormal manifestations such as progressive loss of exhausted T cell effector function and disturbance of cellular energy metabolism. Guizhi decoction， Shengming decoction， and Wendan decoction can correct T cell exhaustion and exert anti-tumor effects through multi-target and multi-pathways by regulating ''Sanjiao-Yingwei'' Qi transformation， and hypoxia inducible factor-1α （HIF-1α） may be one of the main pathways to correct T cell exhaustion. It was found that HIF-1α may be one of the important prognostic indicators in common tumors by bioinformatics. The use of the ''Sanjiao-Yingwei'' Qi transformation method may play an important part in improving the prognosis of tumor patients in clinical practice.关键词：T cell exhaustion;Sanjiao-Yingwei;tumor;immunometabolism;network pharmacology;bioinformatics

发布时间：2024-02-28 - 摘要：Chinese materia medica has a wide range of clinical applications， but it has many active ingredients with different physicochemical properties， and the target organs， action pathways and mechanisms for different ingredients to exert their efficacy are not the same. Therefore， it is difficult to design and develop a co-delivery system loading multiple components of Chinese materia medica to maximize the synergistic therapeutic efficiency. Based on the characteristics of effectiveness and functionality of active ingredients， the strategies for multi-component co-delivery of Chinese materia medica can be categorized into two types：firstly， based on the effectiveness of active ingredients， new carriers such as liposomes， nanoparticles can be constructed to load multi-components of Chinese materia medica. secondly， based on the functionality of some active ingredients of Chinese materia medica， they are employed in the construction of co-delivery system， which can give play to the dual characteristics of their own efficacy and preparation functions. In this paper， we summarized the relevant research progress of the above two types of multi-component co-delivery strategies， and mainly discussed the pharmaceutical functions of the active ingredients in co-delivery systems， in order to find a more suitable multi-component co-delivery strategy， promoting the design and development of new delivery systems of Chinese materia medica.关键词：Chinese materia medica;multi-component;co-delivery;functional carrier;drug delivery system

发布时间：2024-02-28 - 摘要：Diabetic retinopathy（DR） and coronary heart disease（CHD） are both major chronic vascular complications that seriously jeopardize the health of the population and often occur together in clinical practice， it is of great clinical value to actively explore the association between the two in the process of disease development and methods of prevention and treatment of modern medicine and traditional Chinese medicine（TCM）. According to TCM， the heart and eyes physiologically communicate with each other by taking Qi， blood and veins as bridges， blood stasis obstructing collaterals is the common TCM etiology of DR and CHD， whose mechanism involves inflammation， oxidative stress and endothelial dysfunction. Promoting blood circulation and removing blood stasis plays an important role in the same treatment for different diseases and prevention and treatment of comorbidities， possibly by inhibiting the expression of interleukin-1β（IL-1β）， endothelin-1（ET-1） and hypoxia inducible factor-1α/vascular endothelial growth factor（HIF-1α/VEGF）， regulating phosphatidylinositol 3-kinases/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） pathway， initiating adenosine monophosphate（AMP）-activated protein kinase/silent information regulator 1（AMPK/SIRT1） and nuclear transcription factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathways， inhibiting Hippo/Yes-associated protein（Hippo/YAP） signaling pathway， inhibiting mitochondrial permeability transition pore and anti-platelet agglutination for treating DR and CHD， which provides a multi-component， multi-pathway and multi-target selection strategies and ideas for the prevention and treatment of DR and CHD by TCM from a biological perspective. Based on this， subsequent studies should focus on constructing clinically relevant comorbidity models， conducting multicenter prospective studies， and fully utilizing artificial intelligence technology to gain a deeper understanding of the relationship between the two diseases， so as to elucidate the mechanism of promoting blood circulation and removing blood stasis in preventing and treating panvascular diseases.关键词：diabetic retinopathy（DR）;coronary heart disease（CHD）;blood stasis;treating different diseases with the same method;promoting blood circulation and removing blood stasis;molecular mechanism

发布时间：2024-02-28 - 摘要：Cough variant asthma （CVA） is a chronic respiratory disease with cough as its main symptom. The occurrence of CVA is closely related to non-specific airway inflammation， and its pathogenesis involves environmental， genetic， immune， and other factors. In recent years， the advantages of traditional Chinese medicine （TCM） in the treatment of CVA have attracted the attention of experts and scholars in China and abroad， especially its prominent role in regulating immune balance， relieving cough symptoms in CVA patients， and reducing recurrence. T Helper cells 1 （Th1）， T helper cells 2 （Th2）， T helper cells 17 （Th17）， and regulatory T cells （Treg） are derived from CD4+ T cells. Immune imbalance of Th1/Th2 and Th17/Treg is a new hotspot in the pathogenesis of CVA and a potential key target in the treatment of CVA by TCM. Th cell subsets are in dynamic balance under physiological conditions， maintaining respiratory immune homeostasis in which pro-inflammatory cytokines and anti-inflammatory cytokines are balanced. Immature helper T cells （Th0） can be differentiated into Th1， Th2， Th17， Treg， and other cell subsets due to cytokine types in the microenvironment in the stage of CVA maturation. The proliferation of Th2 cells leads to eosinophilic airway inflammation. Excessive differentiation of Th17 cells induces neutrophil airway inflammation. Th1/Th2 and Th17/Treg cells are mutually restricted in number and function， and the immune imbalance of Th1/Th2 and Th17/Treg is easy to aggravate the generation of inflammatory response. Restoring immune balance is particularly important for the airway anti-inflammatory therapy of CVA. In this paper， the imbalance of Th1/Th2 and Th17/Treg and the pathogenesis of CVA were systematically expounded. Meanwhile， the latest research on the regulation of immune imbalance by TCM compound， single TCM， and its effective ingredients in the treatment of CVA was reviewed. It provides ideas and references for revealing the scientific connotation of TCM regulating immune balance therapy of CVA， as well as the development of clinical treatment and basic research of CVA.关键词：traditional Chinese medicine;cough variant asthma;immune balance;T helper cells 1 /T helper cells 2 （Th1/Th2）;Th17/regulatory T cells （Treg）;research progress

发布时间：2024-02-28 - 摘要：Diabetic kidney disease （DKD） is a common microvascular complication of diabetics mellitus （DM） and the leading cause of end-stage renal disease （ESRD）. Renal interstitial fibrosis （RIF） is the primary pathological basis for DKD progression to ESRD， which significantly increases the mortality rate of DKD patients and burdens patients and society， and it is thus a clinical problem that needs to be solved urgently. The pathogenesis of RIF is complex and mainly associated with excessive deposition of extracellular matrix （ECM）， epithelial-mesenchymal transition （EMT）， oxidative stress， inflammation， and autophagy. Multiple signaling pathways such as transforming growth factor-β1/Smad （TGF-β1/Smad）， nuclear transcription factor-κB （NF-κB）， p38 mitogen-activated protein kinase （p38 MAPK）， secretory glycoprotein/β-catenin （Wnt/β-catenin）， mammalian target of rapamycin （mTOR）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， neurogenic site-gap homologous protein （Notch）， and nuclear factor E2-associated factor 2 （Nrf2） mediate the development of RIF， which are currently novel targets for DKD therapy. Due to the complexity of its pathogenesis， the current Western medical treatment mainly focuses on essential treatment to improve metabolism， which has poor efficacy and is difficult to prevent the progression of DKD， so it is significant to find new treatment methods clinically. In recent years， many studies have proved that traditional Chinese medicine can alleviate oxidative stress， inhibit inflammatory response， and regulate cellular autophagy by modulating relevant signaling pathways， so as to treat RIF in DKD， which has the advantages of multi-pathway， multi-targeting， multi-linking， and significant therapeutic efficacy. However， there is still a lack of relevant summary. By reviewing the latest research reports in China and abroad， this article examines the roles of the signaling pathways mentioned above in the occurrence and development of RIF in DKD and the recent research progress in the intervention of RIF in DKD by traditional Chinese medicine via these pathways， aiming to provide new ideas and references for further scientific research and clinical practice.关键词：traditional Chinese medicine;diabetic kidney disease;renal interstitial fibrosis;signaling pathways;research progress

Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.关键词：endoplasmic reticulum stress;atherosclerosis;traditional Chinese medicine;apoptosis;regulation;research progress

发布时间：2024-02-28 - 摘要：Alzheimer's disease （AD） is one of the most common diseases in the elderly population. Its etiology involves multiple pathogenic factors and pathological links such as abnormal deposition of β amyloid protein （Aβ）， hyperphosphorylation of Tau protein， abnormalities of the cholinergic system， oxidative stress， and inflammatory response. However， its specific pathogenesis has not been clarified， and no specific therapeutic drugs have been found. In recent years， more and more studies have paid attention to the potential of chemical components of traditional Chinese medicine （TCM） in the treatment of AD. However， the diversity and complexity of the chemical components of TCM may have a positive impact on multiple pathological links of AD. Researchers have isolated many active components from TCMs， and the effects of treating AD have been confirmed by modern pharmacological studies. Through literature analysis， this article found that the main chemical components of TCM with anti-AD effects were saponins （31%）， flavonoids （24%）， polysaccharides （20%）， lactones （8%）， alkaloids （7%）， phenols （3%）， and other compounds （7%）. Among them， ginsenoside， notoginsenoside， epimedium flavones， puerarin， baicalein， schisandra polysaccharide， angelica polysaccharide， ganoderma lucidum polysaccharide， pachyman， huperzine A， berberine， andrographolide， curcumin， emodin， and gastrodin have been extensively studied in terms of their anti-AD effects， and their mechanisms of pharmacological action have been involved in many aspects of AD pathogenesis. This article reviews the anti-AD activities and possible mechanisms of chemical components of TCM， so as to provide a reference for the development of new drugs for the prevention and treatment of AD.关键词：chemical components of traditional Chinese medicine;Alzheimer's disease;pathogenesis;research review

发布时间：2024-02-28 - 摘要：As people's living standards improve， the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B （NF-κB） in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors， so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer， and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine （TCM） treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad， it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation， oxidative stress， and energy metabolism， and it is involved in mediating inflammation， pancreatic β cell apoptosis， insulin signal transduction， and other physiological functions. Therefore， blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present， Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections， but the adverse reactions are obvious. TCM has been characterized by multi-target， extensive action， and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation， regulating qi and eliminating phlegm， clearing heat and detoxifying， and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper， the association between NF-κB signaling pathway and diabetes was summarized， and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed， so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.关键词：nuclear factor-kappa B （NF-κB）;signaling pathway;diabetes;inflammation;traditional Chinese medicine

发布时间：2024-02-28 - 摘要：Dilated cardiomyopathy （DCM） is characterized by the main pathological changes of global cardiac enlargement， especially left ventricular enlargement. Clinical manifestations include decreased heart function， arrhythmia， thromboembolism， and even sudden death. It is one of the refractory cardiovascular diseases. Conservative drug treatment is still the main approach in clinical practice， but due to its unavoidable side effects such as low blood pressure， it is often difficult to achieve a satisfactory prognosis. The combination of traditional Chinese medicine and Western medicine can effectively improve side effects and enhance efficacy. The research has found that nuclear transcription factors-κB （NF-κB）， adenylate activated protein kinase （AMPK）/mammalian rapamycin target protein （mTOR）， transforming growth factor-β （TGF-β）/Smads， Toll like receptors （TLR） 4/c-Jun amino terminal kinase （JNK）， mitogen activated protein kinase （MAPK）， phosphatidylinositol 3-kinase （PI3K）/protein kinase （Akt）， and other signaling pathways play a crucial regulatory role in the occurrence and development of DCM. Traditional Chinese medicine can improve myocardial fibrosis， reverse ventricular remodeling， alleviate oxidative stress， and achieve anti-inflammatory and other effects by regulating the above signaling pathways， thus improving DCM. Due to its multi-target and multi-mechanism characteristics， it has the advantages of high safety and good tolerance and has become an important part of current clinical treatment.关键词：dilated cardiomyopathy;traditional Chinese medicine;signaling pathway;research progress

发布时间：2024-02-28 - 摘要：Acute pancreatitis （AP） is a common clinical acute abdominal disease， which is characterized by acute onset， rapid development， severe disease， many complications， and high mortality rate. It can progress to severe AP （SAP） if not treated promptly in the early stage. The pathogenesis of AP is complex and involves multiple cellular and molecular levels. It is now clear that oxidative stress and reactive oxygen species （ROS） production are involved in the physiopathological process of AP， which is associated with a low quantity and activity of antioxidant enzymes in pancreatic cells. Nuclear factor E2-related factor 2 （Nrf2） serves as the ''golden key'' to maintain redox homeostasis in tissue cells and constitutes an important signaling pathway for antioxidant response and inflammation in vivo by collaborating with downstream antioxidant enzymes such as heme oxygenase-1 （HO-1）. Traditional Chinese medicine has unique efficacy in treating diseases due to its multi-component， multi-target， multi-drug delivery， and multi-formulation characteristics. Based on the concept of synergy between traditional Chinese and Western medicine， traditional Chinese medicine is becoming a new craze in the treatment of AP. The level of oxidative stress and Nrf2/HO-1 signaling pathway in AP pancreatic tissue are in a dynamic change process， and the intervention of traditional Chinese medicine can clean ROS production， affect the inflammatory pathway， and reduce oxidative stress damage， so as to protect against pancreatic injury. This suggests that this pathway plays an important role in AP. This article reviews the recent literature on the regulation of the Nrf2/HO-1 signaling pathway by traditional Chinese medicine for AP and summarizes that the monomers of traditional Chinese medicine targeting this pathway are mainly heat-clearing and detoxifying， blood-activating and blood-stasis-removing， and Qi benefiting and middle warming， and the compounds of traditional Chinese medicine include Yinchenhao Decoction and QingYi Ⅱ， so as to provide a new direction for the prevention and treatment of AP and further drug development.关键词：acute pancreatitis;oxidative stress;nuclear factor E2-related factor 2/heme oxyagenase-1 （Nrf2/HO-1） signaling pathway;traditional Chinese medicine;research progress

发布时间：2024-02-28 - 摘要：Xiaoyaowan has the effects of soothing the liver， invigorating the spleen， regulating menstruation， and nourishing blood. It is often used to treat the distending pain of the chest and hypochondriac， loss of appetite， dizziness， and irregular menstruation caused by liver depression and spleen deficiency. The formula originated from the Sinisan of Treatise on Cold Damage（《伤寒论》） in the Han dynasty and was officially formulated in the Song dynasty's Taiping Royal Prescriptions（《太平惠民合计局方》）. In the Ming and Qing dynasties， it was developed into more comprehensive formulas such as modified Bazhentang， modified Xiaoyaowan， and other formulas. In recent years， Xiaoyaowan has become a classic formula for treating many symptoms of liver depression. The Pharmacopoeia of the People's Republic of China（《中华人民共和国药典》）， 2020 edition， records Xiaoyaowan and modified Xiaoyaowan. Modern clinical research has further expanded the therapeutic range of this formula. Through literature research， it is found that there are certain reports on the clinical application and quality analysis of Xiaoyaowan， but the relevant literature lacks collation so far. Therefore， relevant literature was consulted and sorted out. The paper summarized the treatment of mammary hyperplasia， depression， irregular menstruation， melasma， menopausal syndrome， and polycystic ovary syndrome with Xiaoyaowan， as well as the quality analysis of paeoniflorin， ferulic acid， and glycyrrhizinic acid of Xiaoyaowan. It is expected to lay a foundation for further research on clinical application， pharmacodynamic mechanism， and quality control of this classic formula.关键词：Xiaoyaowan;soothing liver and invigorating spleen;clinical effects;quality analysis;quality marker（Q-Marker）;review
