The Pharmacovigilance Guideline for Clinical Application of Chinese Patent Medicine for External Use （T/CACM 1563.5—2024）， the first guideline in China specializing for the clinical safety of Chinese patent medicines for external use， was led by the Institute of Basic Research in Clinical Medicine，China Academy of Chinese Medical Sciences，and jointly developed by more than 30 research institutions of medical sciences across the country. Aiming to standardize the pharmacovigilance activities in the clinical application of Chinese patent medicines for external use，the guideline systematically categorizes potential risks and proposes prevention and control measures that cover 11 core sections of risk monitoring and reporting， signal identification，as well as assessment and control， addressing the gap in domestic and international standardization of this field. The compilation of this guideline strictly adhered to international norms and domestic regulations， involving multiple rounds of expert consultations，hybrid interviews， and evidence integration （covering literature，medical insurance，essential medicine，pharmacopoeia data， and regulatory information）. With the scope of application defined to include medical institutions， pharmaceutical manufacturers and distribution enterprises，as well as regulatory authorities， the guideline focuses on key issues such as inherent medicine risks，quality risks，off-label use，risks of combination therapy，and the safety in special populations. During the compilation，core discrepancies such as the definition of application scope and quality risk control were addressed to ensure alignment with regulations such as the Drug Administration Law of the People's Republic of China and the Good Pharmacovigilance Practice. The guideline is registered internationally （PREPARE—2022CN463）. In the future，the implementation of the guideline will be promoted through hierarchical dissemination，dynamic revision，and post-effectiveness evaluation， contributing to rational clinical use and improved patient safety.

ObjectiveTo investigate the effects of Yishen Juanbi pills （YSJB）-containing bone marrow fluid on the migration and differentiation phenotypes of CD4⁺T lymphocytes based on the stromal cell-derived factor-1/chemokine receptor 4 （SDF-1/CXCR4） signaling pathway. MethodsPrimary CD4⁺T lymphocytes were isolated from mice using magnetic bead separation and identified for purity by flow cytometry. A CD4⁺T lymphocyte culture system was then established to observe the effects of SDF-1 on CD4⁺T-cell migration and differentiation. On this basis， the experimental groups included the Sham group， the ovariectomy （OVX） group， the Sham+collagen-induced arthritis （CIA） group， the OVX+CIA group， the Sham+CIA+YSJB group （2.16 g·kg^-1）， the OVX+CIA+YSJB group （2.16 g·kg^-1）， and the OVX+CIA+methotrexate （MTX） group （1.5 mg·kg^-1）. Bone marrow fluid from each group was prepared according to previous methods and added to the CD4⁺ T-cell culture system at 5% （v/v）. Transwell assays were used to examine CD4⁺T-cell migration in each group. Real-time PCR was used to measure the mRNA expression levels of interleukin （IL）-17， tumor necrosis factor-α （TNF-α）， retinoic-acid-related orphan receptor γt （RORγt）， IL-10， transforming growth factor-β （TGF-β）， forkhead box P3 （FoxP3）， CXCR4， phosphoinositide 3-kinase （PI3K）， and protein kinase B （Akt）. Western blot was used to detect the expression of helper T （Th）17/regulatory T （Treg） cell signature factors （RORγt， FoxP3）， CXCR4， PI3K， phosphorylated （p）-PI3K， Akt， and p-Akt. In a separate set of experiments， cells were divided into the Sham group， OVX+CIA group， OVX+CIA+CXCR4 antagonist AMD3100 group， and OVX+CIA+YSJB+AMD3100 group to observe changes in the above indicators following AMD3100 intervention. ResultsCompared with the Sham group， the number of migrated cells in the lower chamber was significantly increased in the Sham+CIA and OVX+CIA groups （P<0.05， P<0.01）. The mRNA expression of RORγt， IL-17， TNF-α， CXCR4， PI3K， and Akt was significantly upregulated， whereas FoxP3， IL-10， and TGF-β mRNA expression was significantly decreased （P<0.05， P<0.01）. Protein expression of RORγt， CXCR4， p-PI3K/PI3K， and p-Akt/Akt was significantly increased， while FoxP3 protein expression was markedly decreased （P<0.05， P<0.01）. Compared with the OVX+CIA group， the OVX+CIA+YSJB group and OVX+CIA+MTX group showed significantly reduced migration （P<0.05）， mRNA expression of RORγt， IL-17， TNF-α， CXCR4， PI3K， and Akt was also significantly decreased， while FoxP3， IL-10， and TGF-β mRNA expression was significantly increased （P<0.05， P<0.01）. RORγt protein expression was significantly downregulated， and FoxP3 protein expression markedly upregulated （P<0.05）. In the OVX+CIA+YSJB group， CXCR4， p-PI3K/PI3K， and p-Akt/Akt protein expression was significantly decreased （P<0.05）. Compared with the OVX+CIA group， RORγt， CXCR4， PI3K， and Akt mRNA expression in CD4⁺T cells was significantly decreased in the OVX+CIA+AMD3100 group and the OVX+CIA+YSJB+AMD3100 group， while FoxP3 mRNA and protein expression was significantly upregulated （P<0.05， P<0.01）. RORγt， CXCR4， p-PI3K/PI3K， and p-Akt/Akt protein expression was also markedly decreased （P<0.05， P<0.01）. Compared with the OVX+CIA+AMD3100 group， the OVX+CIA+YSJB+AMD3100 group showed significantly decreased RORγt and Akt mRNA expression （P<0.05） and significantly lower p-Akt/Akt protein expression （P<0.05）. ConclusionYSJB-containing bone marrow fluid suppresses CD4⁺T-cell migration and regulates Th17/Treg balance by downregulating Th17-associated signature factors and upregulating Treg-associated signature factors through inhibition of the SDF-1/CXCR4 signaling pathway and PI3K/Akt signaling pathway. The SDF-1/CXCR4 signaling pathway is one of the targets through which YSJB inhibits CD4⁺T-cell differentiation.

Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Objective To analyze the value of serum neutrophil count (NEUT), homocysteine (Hcy), adiponectin (APN) and blood glucose in predicting the occurrence of acute myocardial infarction (AMI) in patients with coronary heart disease. Methods The clinical data of 98 patients with coronary heart disease who were admitted to the hospital from March 2022 to March 2024 were collected retrospectively. Patients included were divided into AMI group (n=33) and non-AMI group (n=65) according to the presence and absence of AMI. Baseline data, complications, ultrasound examination data and laboratory examination data were collected. Multivariate logistic regression analysis was performed to identify the influencing factors of AMI in patients with coronary heart disease. The receiver operating characteristic curves were used to evaluate the predictive value of NEUT, Hcy, APN and blood glucose for AMI in patients with coronary heart disease. Results The levels of fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (2hPG), glycosylated hemoglobin (HbA1c), NEUT, APN, Hcy, N-terminal pro B-type natriuretic peptide (NT-proBNP), C-reactive protein (CRP), red blood cell distribution width (RDW) and white blood cell (WBC) in the AMI group were higher than those in the non-AMI group (P<0.05). Logistic regression analysis found that FPG, 2hPG, HbA1c, NEUT, APN, Hcy, NT-proBNP, CRP, RDW, and WBC were independent influencing factors of AMI in patients with coronary heart disease (P<0.05). ROC curves indicated that the levels of FPG, 2hPG, HbA1c, NEUT, APN and Hcy were abnormally elevated in patients with coronary heart disease. Above indicators were helpful for predicting the occurrence of AMI. The area under the curve (AUC) and sensitivity of FPG for predicting AMI in patients with coronary heart disease were the best (P<0.05). Conclusion Abnormal elevated levels of FPG, 2hPG, HbA1c, NEUT, APN and Hcy are independent risk factors for AMI in patients with coronary heart disease. All of these indicators have predictive value.

ObjectiveTo compare the hepatic bile acid profile between a mouse model of metabolic-associated steatohepatitis （MASH） induced by a high-fat， high-sugar， and high-cholesterol diet combined with intraperitoneal injection of 10% carbon tetrachloride （CCl₄） and MASH cases in clinical practice， and to investigate the feasibility of this model in studying drug interventions on bile acid profile in MASH. MethodsA total of 30 male C57BL/6J mice were randomly divided into control group and model group， with 15 mice in each group. The mice in the control group were given normal diet and drinking water and weekly injections of olive oil， and those in the model group were given a high-fat， high-sugar， and high-cholesterol diet， high-sugar drinking water， and weekly injections of CCl₄+olive oil. At the end of weeks 8， 12， and 16， 5 mice were selected from each group to collect samples. Behavioral assessments were performed， and body weight and liver wet weight were measured； liver pathology and lipid deposition were evaluated by HE staining， SAF scoring， oil Red O staining， the semi-quantitative analysis of stained area， the serum levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST）， and liver triglyceride （TG） content； Sirius Red staining was performed for liver tissue to assess liver fibrosis； ultra-performance liquid chromatography-tandem mass spectrometry and targeted metabolomics were used to measure the hepatic bile acid profile， including cholic acid （CA）， glycocholic acid （GCA）， chenodeoxycholic acid （CDCA）， glycochenodeoxycholic acid （GCDCA）， ursodeoxycholic acid （UDCA）， tauroursodeoxycholic acid （TUDCA）， hyodeoxycholic acid （HDCA）， and glycodeoxycholic acid （GDCA）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. ResultsCompared with the control group at the same time point， the model group had disheveled and dull fur， reduced activity， and relatively slow reactions at weeks 8， 12， and 16， as well as significant increases in liver wet weight （P<0.05）， the serum level of ALT （P<0.05）， the content of TG in the liver （P<0.05）， and SAF score （P<0.05）. As for the differentially expressed bile acids in liver tissue， compared with the control group at week 8， the model group had significantly higher levels of CA and CDCA and significantly lower levels of UDCA， TUDCA， HDCA， and GDCA （all P<0.05）； compared with the control group at week 12， the model group had significantly higher levels of CA， GCA， CDCA， and GCDCA and significantly lower levels of UDCA and HDCA （all P<0.05）； compared with the control group at week 16， the model group had significantly higher levels of CA， GCA， CDCA， GCDCA， and TUDCA and significantly lower levels of UDCA， HDCA， and GDCA （all P<0.05）. As for the differentially expressed bile acids in the bile acid pool of liver tissue， compared with the control group at week 8， the model group had significantly higher levels of CA and CDCA and significantly lower levels of UDCA， TUDCA， GDCA， and HDCA （all P<0.05）； compared with the control group at weeks 12 and 16， the model group had significantly higher levels of GCA and GCDCA and significantly lower levels of UDCA， GDCA， and HDCA （all P<0.05）. ConclusionThere are significant changes in the hepatic bile acid profile in a mouse model of MASH induced by a high-fat， high-sugar， and high-cholesterol diet combined with CCl₄， which are similar to the changes in bile acids in MASH cases in clinical practice， suggesting that this model can be used to explore the interventional effect of drugs on the bile acid profile in MASH.

Rheumatic diseases,as a complex class of chronic immune-mediated disorders,involve interplay among genetics,environment,and immunity in their pathogenesis,which remains incompletely elucidated to date.In recent years,with the advancement of epigenetic research,particularly in the field of RNA modifications,the role of m6 A methylation in rheumatic diseases has increasingly garnered attention.Traditional Chinese medicine(TCM),as the indigenous medical system of China,has accumulated extensive experience in the treatment of rheumatic diseases.This article systematically reviewed the research progress of TCM in treating rheumatic diseases such as rheumatoid arthritis,systemic lupus erythematosus,Sj?gren's syndrome,ankylosing spondylitis,and osteoarthritis,as well as improving bone metabolism abnormalities closely related to rheumatic diseases,through regulating m6 A methylation.The aim is to provide novel insights into the treatment of rheumatic diseases with TCM and to offer theoretical support for the development of related functional drugs.

Numerous c-mesenchymal-epithelial transition (c-MET) inhibitors have been reported as potential anticancer agents. However, most fail to enter clinical trials owing to poor efficacy or drug resistance. To date, the scaffold-based chemical space of small-molecule c-MET inhibitors has not been analyzed. In this study, we constructed the largest c-MET dataset, which included 2,278 molecules with different structures, by inhibiting the half maximal inhibitory concentration (IC₅₀) of kinase activity. No significant differences in drug-like properties were observed between active molecules (1,228) and inactive molecules (1,050), including chemical space coverage, physicochemical properties, and absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles. The higher chemical diversity of the active molecules was downscaled using t-distributed stochastic neighbor embedding (t-SNE) high-dimensional data. Further clustering and chemical space networks (CSNs) analyses revealed commonly used scaffolds for c-MET inhibitors, such as M5, M7, and M8. Activity cliffs and structural alerts were used to reveal "dead ends" and "safe bets" for c-MET, as well as dominant structural fragments consisting of pyridazinones, triazoles, and pyrazines. Finally, the decision tree model precisely indicated the key structural features required to constitute active c-MET inhibitor molecules, including at least three aromatic heterocycles, five aromatic nitrogen atoms, and eight nitrogen-oxygen atoms. Overall, our analyses revealed potential structure-activity relationship (SAR) patterns for c-MET inhibitors, which can inform the screening of new compounds and guide future optimization efforts.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.
