ObjectiveTo establish an animal model of atrial fibrillation（AF） that accurately reflects the phlegm-heat and blood stasis（TRYZ） pathogenesis in traditional Chinese medicine. MethodsForty SPF-grade SD rats were randomly assigned using a random number table to the following groups：the control group， the TRYZ+AF group，the AF group and the TRYZ group， with ten rats in each group. The TRYZ+AF and TRYZ groups underwent a high-fat diet combined with intraperitoneal lipopolysaccharide（LPS） injection to simulate the pathological alterations of TRYZ syndrome. Groups TRYZ+AF and AF were induced with acetylcholine-calcium chloride（Ach-CaCl₂） via caudal vein injection to induce AF. The control group received no intervention and was maintained under normal conditions. The modeling period lasted 3 weeks. Electrocardiography was used to assess AF episodes and duration， echocardiography evaluated left atrial dimensions and cardiac function， fully automated biochemical analyzer measured the levels of total cholesterol（TC）， triglycerides（TG）， high-density lipoprotein cholesterol（HDL-C） and low-density lipoprotein cholesterol（LDL-C）， hemoreometer analyzed the whole blood viscosity， plasma viscosity， and whole blood reduced viscosity， a coagulation analyzer assessed prothrombin time（PT）， activated partial thromboplastin time（APTT）， thrombin time（TT）， and fibrinogen（FIB）， enzyme-linked immunosorbent assay（ELISA） was used to determine the levels of C-reactive protein（CRP）， interleukin（IL）-1β， IL-6， IL-17， tumour necrosis factor（TNF）-α， matrix metalloproteinase-9（MMP-9）， galectin-3（Gal-3）， Collagen Ⅰ， and α-smooth muscle actin（α-SMA）. Hematoxylin-eosin（HE） staining and Masson's trichrome staining were used to analyze pathological changes in atrial myocardium， Western blot was employed to detect MMP-9， Collagen Ⅰ and α-SMA protein expression in myocardial tissue， real-time quantitative polymerase chain reaction（Real-time PCR） evaluated fibrous factor gene expression levels. Changes in the TRYZ syndrome were assessed via body weight， tongue color［red（R）， green（G）， and blue（B）］， and rectal temperature. Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） was employed to detect differential metabolites between the control group and the TRYZ+AF group. ResultsFollowing three weeks of sustained modeling， compared with the control group， rats in the TRYZ+AF and the TRYZ groups exhibited reduced body weight， dry faeces， elevated rectal temperature， dark red tongue， decreased RGB values on the tongue surface， and markedly elevated TC and LDL-C levels（P<0.05， P<0.01）. The TRYZ+AF， TRYZ， and AF groups exhibited significantly decreased TT， APTT and PT， along with markedly elevated whole blood viscosity and FIB（P<0.05， P<0.01）. Rats in the TRYZ+AF and AF groups exhibited AF rhythm， markedly decreased heart rate， prolonged RR intervals， enlarged left atrium， and significantly reduced ejection fraction and shortening fraction（P<0.05， P<0.01）. Serum levels of CRP， IL-1β， IL-6， IL-17， TNF-α， MMP-9， Gal-3， Collagen Ⅰ， and α-SMA were elevated in rats from the TRYZ+AF， TRYZ， and AF groups compared to the control group， with the most pronounced increase observed in the TRYZ+AF group（P<0.05， P<0.01）. Histopathology revealed that the collagen fiber deposition in the atrial of rats in the TRYZ+AF， TRYZ and AF groups was higher than that in the control group（P<0.05， P<0.01）. Western blot and Real-time PCR results further demonstrated that the protein and mRNA expression levels of MMP-9， Collagen Ⅰ and α-SMA in the myocardial tissue of the TRYZ+AF group were higher than those in the other three groups（P<0.05， P<0.01）. Metabolomic analysis revealed 173 differentially expressed metabolites in the TRYZ+AF group and the control group， primarily enriched in pathways such as glycerophospholipid metabolism and glycolysis/gluconeogenesis. ConclusionThis study successfully establishes a rat model of AF integrated with the TRYZ syndrome， demonstrating the pathological process where the interactions of phlegm， heat and stasis jointly trigger tremor， this provides a reliable experimental tool for in-depth research into the biological basis of this disease syndrome.

As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Symptom and syndrome efficacy evaluation scales are indispensable tools for clinical efficacy assessment in traditional Chinese medicine （TCM）， and hold significant value at all stages of new drug research development for spleen and stomach diseases. These scales can provide scientific basis for clinical positioning， efficacy evaluation， and expansion of indications of new drugs. By analyzing the current hotspots and difficulties in research， this study aims to explore the important significance of these scales in the development of new drugs for spleen and stomach diseases， summarize the domestic research progress， and conduct comparative analyses with international studies. Future development trends are also discussed in order to promote the application of symptom and syndrome efficacy evaluation scales in the development of new drugs for spleen and stomach diseases and to advance the moder-nization process of TCM.

The brain-gut interaction theory is a multidimensional integrative concept based on the brain-gut axis， involving neural， endocrine， and immune regulatory networks as well as the gut microbiota. Zang-fu organs （脏腑） theory in traditional Chinese medicine （TCM） shows a high degree of consistency with the brain-gut interaction theory， and the core functions such as the spleen and stomach governing the ascending of the clear and descending of the turbid， the liver governing the free flow of qi， and the heart governing mental and emotional activities are closely associated with the multi-level regulatory mechanisms of the brain-gut axis. TCM therapy can modulate brain-gut interactions through multiple pathways in the treatment of spleen and stomach diseases， including the regulation of gastrointestinal hormone secretion， neurotransmitter levels， the hypothalamic-pituitary-adrenal （HPA） axis， immune homeostasis and inflammatory responses， as well as the gut microecology. However， current basic research on the brain-gut interaction theory in TCM for spleen and stomach diseases still faces several challenges， such as difficulties in integrating TCM spleen-stomach theory with modern pathophysiology， lack of innovation in research concepts， and limitations in research methodologies. It is therefore proposed that multidisciplinary collaboration， multi-omics technologies， and targeted research approaches should be adopted to provide more comprehensive methods for basic research on TCM spleen and stomach diseases， thereby promoting the in-depth development of brain-gut interaction theory.

AIM:To investigate the therapeutic effect of mitochondrial fission inhibitor-1(Mdivi-1)on experi-mental autoimmune encephalomyelitis(EAE)in mice,and to explore its mechanism.METHODS:The mice immunized with myelin oligodendrocyte glycoprotein peptide fragment 35-55(MOG35-55)were randomly divided into DMSO model group and Mdivi-1 intervention group.All mice were sacrificed on the 28th day after the first immunization.The demyelination was analyzed by Luxol fast blue staining.The protective mechanism of Mdivi-1 in the spinal cord tissue was investigated by immunofluorescence staining,TUNEL staining and the in vitro experiment with MO3.13 oligodendrocytes treated with staurosporine.The mitochondrial depolarization was detected by JC-1 staining,the cell injury was checked by LDH leakage,and the viability of MO3.13 oligodendrocytes was determined by MTT assay.RESULTS:Compared with DMSO model group,the demyelinating injury was alleviated and the proportion of apoptotic CC1+ oligodendrocytes in Mdivi-1 group was decreased.The cleaved caspase-3,caspase-9,cytochrome C and Bax protein expression levels in the spinal cord of Mdivi-1-treated mice was also attenuated.The in vitro MO3.13 cell experiments suggested that Mdivi-1 inhibited MO3.13 cell mitochondrial depolarization,attenuated the cell damage and increased the cell viability.CONCLUSION:Mdivi-1 pro-tects against the myelin injury in EAE mice,which may be related to the suppression of oligodendrocyte apoptosis.

Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

ObjectiveTo explore the effect of Jiangtang Xiaozhi tablet （JTXZT） on metabolic dysfunction-associated fatty liver disease and to study the mechanism from the perspective of circadian clock-related genes such as circadian locomotor output cycles kaput （CLOCK）， brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 （BMAL1）， reverse-eritroblastosis receptor （REV-ERB）α and β. MethodA total of 50 male SPF C57BL/6J mice were randomized into normal group （n=10） and modeling group （n=40）. The normal group was fed with normal diet， and the modeling group with high-fat diet for 4 weeks. Then the model mice were randomly classified into model group， high-dose （12.5 g·kg^-1） and low-dose （6.25 g·kg^-1） Jiangtang Xiaozhi tablet groups， and orlistat group （70 mg·kg^-1）， with 10 mice in each group. The normal group and model group received equivalent volume of distilled water （8 weeks）. Then， the body weight of mice was measured， and the content of serum triglyceride （TG）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） was determined with biochemical method. Serum content of free fatty acid （FFA） and leptin was detected by enzyme-linked immunosorbent assay （ELISA）. Pathological changes of liver tissue and epididymal adipose tissue were observed based on hematoxylin-eosin （HE） staining. Liver fibrosis was examined based on Masson's trichrome staining， and changes of lipids based on oil red O staining. The expression of CLOCK， BMAL1， REV-ERBα， and REV-ERBβ was detected by Western blot and immunohistochemistry assay. ResultCompared with the normal group， the model group had high content of TG， TC， LDL-C， HDL-C， AST， ALT， FFA， and leptin （P<0.05， P<0.01）， showed ballooning degeneration and focal microvesicular steatosis of liver cells， enlarged adipocytes， and inflammatory cell clusters and fibrous tissue hyperplasia， and displayed increased protein expression of sterol regulatory element binding protein （SREBP） 1 and peroxisome proliferators-activated receptor （PPAR）γ （P<0.01） and decreased protein expression of PPARα （P<0.05）， CLOCK， BMAL1， REV-ERBα and β （P<0.05， P<0.01）. Compared with the model group， JTXZT-H group down-regulated the content of TG， TC， LDL-C， HDL-C， AST， ALT， FFA， and leptin in mice （P<0.05， P<0.01）， and the JTXZT groups demonstrated reduction in the degree and range of ballooning degeneration of liver tissue， alleviation of the compression of hepatic sinusoidal tissue， unobvious inflammatory cell infiltration and fibrous tissue proliferation， reduction in the expression of SREBP1 and PPARγ （P<0.05， P<0.01）， and rise of the protein expression of PPARα （P<0.01）， CLOCK， BMAL1， REV-ERBα， and REV-ERBβ （P<0.05， P<0.01）. ConclusionJTXZT can significantly alleviate the metabolic dysfunction-associated fatty liver disease in mice caused by high-fat diet. The mechanism is the likelihood that it regulates downstream related lipid metabolism proteins （such as SREBP1， PPARγ， and PPARα）.

In the clinical practice of rheumatic immune diseases in traditional Chinese medicine （TCM），it`s still unclear about the dominant diseases and breakthrough points. It`s urgent missions to formulate TCM diagnosis and treatment guidelines widely recognized and integrated by traditional Chinese medicine and Western medicine. In order to clarify the dominant diseases and breakthrough points in rheumatism，China association of Chinese medicine initiated a research group covering experts in the field of rheumatism of traditional Chinese medicine and Western medicine. Based on questionnaire survey and on-site discussion，experts had reached the following consensus. Evidence-based medicine research using modern medical methods and scientific methods should be carried out to provide objective clinical evidences. "Four mutuality" were put forward as the basis for the work of integrated traditional Chinese and Western medicine，that is the mutual communication using the exchangeable context，the mutual explanation using common theories，the mutual certification using common standards，and the mutual integration using common means. Key works should focus on solving refractory rheumatism in the future. In terms of dominant diseases and breakthrough points，this paper introduces 21 breakthrough points in 6 dominant diseases，including rheumatoid arthritis，ankylosing spondylitis，Sjogren's syndrome，hyperuricemia and gout，systemic lupus erythematosus and fibromyalgia syndrome. Advice on this discussion can provide valuable references for developing the treatment scheme of rheumatism with TCM and integrated Chinese and Western medicine and clinical practice and scientific research.

Objective:To explore the molecular mechanism of Jiangtang Xiaozhi tablets （JTXZT） in the treatment of non-alcoholic fatty liver disease （NAFLD） by means of network pharmacology and molecular docking. Method:With the help of traditional Chinese medicine （TCM） Systems Pharmacology Database and Analysis Platform （TCMSP）， TCMs Integrated Database （TCMID）， Encyclopedia of TCM （ETCM） and Bioinformatics Analysis Tool for Molecular Mechanism of TCM （BATMAN-TCM）， the chemical compositions of medicinal materials in JTXZT were obtained， the compound targets were predicted in SwissTargetPrediction database and STITCH database. The targets of NAFLD were searched by The Human Gene Database （GeneCards）， Online Mendelian Inheritance in Man （OMIM）， Therapeutic Target Database （TTD） and DisGeNET， and intersection analysis was performed with the targets of the active ingredients to obtain the targets of JTXZT for treatment of NAFLD. Based on STRING 11.0 database， the protein-protein interaction （PPI） network of therapeutic targets was constructed， and the enrichment analysis of therapeutic targets was carried out by DAVID 6.8. Finally， the interaction characteristics of key components and core therapeutic targets of JTXZT for treatment of NAFLD were verified based on molecular docking. Result:The key components of JTXZT for treatment of NAFLD were quercetin， luteolin， kaempferol， berberine， isorhamnetin， betulinic acid， oleanolic acid， ursolic acid. formononetin and hexitol， and the core targets of JTXZT for treatment of NAFLD were mitogen-activated protein kinase 1 （MAPK1）， Jun proto-oncogene， activator protein-1 （AP-1） transcription factor subunit （JUN）， MAPK3， protein kinase B1 （AKT1 or Akt1）， tumor protein p53 （TP53）， E1A binding protein p300 （EP300）， Fos proto-oncogene， AP-1 transcription factor subunit （FOS）， tumor necrosis factor （TNF），amyloid beta precursor protein （APP） and cytochrome P450 family 2 subfamily E member 1 （CYP2E1）. Biological function and pathway enrichment analysis showed that JTXZT mainly through xenobiotic metabolic process， oxidation-reduction process， cholesterol metabolic process and other biological processes， regulating phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， MAPK signaling pathway， NAFLD and insulin signaling pathway to play a role in the treatment of NAFLD. The results of molecular docking showed that the active components of JTXZT had a good affinity with the core targets of JTXZT for the treatment of NAFLD. Conclusion:JTXZT treats NAFLD through multiple active components， multiple key targets and multiple action pathways.

Objective:To study the extraction method and characteristics of vesicle-like nanoparticles （VLNs） in Astragali Radix decoction， and to explore the mechanism of the VLNs in reducing blood glucose by regulating the gut microbiota of db/db diabetic mice. Method:Ultracentrifugation and size exclusion chromatography were used to enrich VLNs from Astragali Radix decoction， and the morphology， particle size and concentration of the VLNs were analyzed by transmission electron microscope and nanoparticle tracking analyzer. The db/db diabetic mice were randomly divided into model group， Astragali Radix VLNs high-， medium- and low-dose （21.1， 10.6， 5.3 g·kg^-1） groups and metformin group （0.25 g·kg^-1） according to their blood glucose levels. There were 7 mice in each group， and another 7 C57BL/6 mice were set as the normal group. The mice were given intragastrically for 3 weeks （once a day）， and the changes of fasting blood glucose were observed every week. Hematoxylin-eosin （HE） staining was used to observe the pathological morphology of liver and pancreas of diabetic mice. The feces of mice were collected for 16S rRNA diversity detection of intestinal microbes. Result:The size of the nanoparticles obtained by the two methods was about 200 nm. Astragali Radix VLNs extracted by ultracentrifugation had a typical saucer-like shape with the concentration of 3.0×10¹¹ particles·mL^-1. The morphology of Astragali Radix VLNs obtained by size exclusion chromatography was relatively poor with the concentration of 2.2×10¹¹ particles·mL^-1. After 3 weeks of administration， compared with the model group， Astragali Radix VLNs high-， medium- and low-dose groups could significantly reduce the fasting blood glucose of diabetic mice （P<0.05， P<0.01）. The VLNs could improve the gut microbiota dysbiosis， significantly decrease the ratio of Firmicutes/Bacteroidota， and increase the relative abundance of beneficial bacteria and reduce the relative abundance of harmful bacteria. Conclusion:Astragali Radix VLNs may reduce the blood glucose of db/db diabetic mice by adjusting the ratio of Firmicutes/Bacteroidota in the intestinal flora.
