ObjectiveTo investigate the mechanisms by which Renshentang treats atherosclerosis （AS） in mice， focusing on the regulation of endothelial inflammatory responses mediated by transient receptor potential vanilloid subtype 1 （TRPV1）. MethodsAn AS model was established in apolipoprotein E knockout （ApoE^-/-） mice fed a high-fat diet. The mice were randomly divided into a simvastatin group （0.02 g·kg^-1·d^-1） and low-， medium-， and high-dose Renshentang groups （1.77， 3.54， 7.08 g·kg^-1·d^-1）， with 12 mice in each group. ApoE^-/- mice were fed a high-fat diet and treated simultaneously. C57BL/6J mice fed a normal diet served as the normal group （n=9）. After continuous administration for 12 weeks， mice were anesthetized and the aortas were collected. Oil Red O staining was used to observe lipid plaque formation in the aorta. Hematoxylin-eosin （HE） staining was performed to examine pathological changes in the aortic root. Immunohistochemistry was used to analyze the levels of pro-inflammatory factors tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）， as well as the expression of TRPV1， phosphorylated phosphoinositide 3-kinase （p-PI3K）， and phosphorylated protein kinase B （p-Akt） in the aortic root. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect endothelial nitric oxide synthase （eNOS） mRNA expression in the aorta， and Western blot was used to detect TRPV1 protein expression. ResultsCompared with the normal group， the model group showed a significant increase in aortic plaque formation （P<0.01） and significantly elevated levels of TNF-α and IL-1β in the aortic root （P<0.01）. The expression levels of TRPV1， p-PI3K， and p-Akt were decreased （P<0.05， P<0.01）， and eNOS mRNA expression was reduced （P<0.05， P<0.01）. Compared with the model group， all Renshentang groups significantly reduced aortic plaque formation （P<0.01）， significantly decreased TNF-α and IL-1β levels （P<0.01）， and markedly increased the expression levels of TRPV1， p-PI3K， p-Akt， and eNOS mRNA （P<0.05， P<0.01）. ConclusionRenshentang may inhibit endothelial inflammation and suppress the formation of AS by increasing TRPV1 protein expression and up-regulating the PI3K/Akt/eNOS signaling pathway， which may be one of the molecular mechanisms underlying its therapeutic effect against AS.

BACKGROUND:The exact pathogenesis of temporomandibular joint osteoarthritis is currently unclear.Traditional clinical treatment strategies for temporomandibular joint osteoarthritis are symptomatic treatments such as pain relief and reduction of inflammation,which can stop the progression of the disease to a certain degree but cannot reverse the destruction of the cartilage.Cartilage degeneration,as one of the most prominent pathologic features in the development of temporomandibular joint osteoarthritis,has been the subject of an increasing number of studies that focus on its pathogenesis.Consequently,we hope to provide an ideal radical solution for the regeneration of the temporomandibular joint.OBJECTIVE:To review the progress of research on cartilage degeneration in temporomandibular joint osteoarthritis.METHODS:The search terms were"temporomandibular joint osteoarthritis,degradation of cartilage matrix,synovitis,oxidative stress,chondrocyte hypertrophy,chondrocyte apoptosis,ferroptosis,autophagy,angiogenesis,extracellular vesicles"in Chinese and English.Literature search was conducted in PubMed database and CNKI,and the time limit for the search was from January 2004 to October 2024.Screening was performed by analyzing and reading the literature,and according to the inclusion and exclusion criteria,81 papers were finally included for review.RESULTS AND CONCLUSION:(1)Increased secretion of cartilage matrix degrading enzymes causes degradation of the cartilage matrix,leading to cartilage degeneration.(2)Synovitis promotes cartilage degeneration through macrophage M1-type polarization and production of inflammatory mediators.(3)Oxidative stress promotes cartilage degeneration by exacerbating the inflammatory response through overproduction of reactive oxygen species.(4)Chondrocyte phenotypic changes and death lead to the decrease of cartilage matrix synthesis,resulting in cartilage degeneration.(5)Blood vessels of subchondral bone penetrate the calcified cartilage layer to reach the superficial cartilage layer,which destroys the cartilage structure and leads to cartilage degeneration.(6)Bioactive substances carried by serum-derived extracellular vesicles in inflammatory states also promote cartilage degeneration in temporomandibular joint osteoarthritis.

Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

OBJECTIVE To form an expert consensus addressing clinical issues regarding the use of parenteral direct thrombin inhibitors （DTIs） in special populations. METHODS Led by the Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital（the Affiliated Hospital of UESTC）， a multidisciplinary working group was formed comprising experts from multiple fields， including clinical pharmacy， cardiac surgery， obstetrics， pediatrics and evidence-based medicine. Through literature review and the Delphi method， clinical questions regarding the efficacy and safety of parenteral DTIs used in special populations were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” （PICO） framework；systematic searches were conducted in CJFD， PubMed， Embase and other databases. Relevant evidence from randomized controlled trials，cohort studies and systematic reviews were included and synthesized. Evidence quality was assessed using the Grading of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through three rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven clinical questions were ultimately selected （with a consensus rate exceeding 90%）， resulting in the formulation of seven recommendations on the use of parenteral DTIs in special populations， including children， pregnant women， patients with hepatic or renal impairment， patients with mesenteric venous thrombosis， and individuals with thrombophilia. These recommendations clarify the preferred agents， dosing ranges， monitoring parameters， and safety management strategies for parenteral DTIs in these special populations. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in special populations.

This paper summarizes the clinical experience in the syndrome differentiation and treatment of rosacea using the method of venting heat and resolving stagnation. It is considered that the key pathogenesis of rosacea is the accumulation of heat with stagnation. Accordingly， the method of venting heat and resolving stagnation is proposed， which vents and disperses constraint heat by applying approaches such as dredging defensive qi， clearing qi， venting ying （营） level， and cooling blood， while eliminating stagnation and masses through regulating qi， resolving dampness， dispelling phlegm and removing stasis. In clinical practice， a core prescription for venting heat and resolving stagnation is formulated， with flexible modifications made according to the clinical characteristics of different rosacea subtypes， including erythematotelangiectatic， papulopustular， phymatous， and ocular types， thereby providing therapeutic insights for the treatment of rosacea with traditional Chinese medicine.

BackgroundSchizophrenia， as a common chronic mental disorder， although second-generation antipsychotic drugs have shown significant efficacy in alleviating positive symptoms， the widespread cognitive dysfunction among patients remains a challenge in clinical treatment. Traditional Chinese medicine has unique advantages in the treatment of mental disorders. However， the current clinical research on the combination of Wendan Decoction and antipsychotic drugs for schizophrenia varies in quality， and there is a lack of systematic reviews evaluating its effects on cognitive improvement and safety. ObjectiveTo systematically evaluate the effects of modified Wendan Decoction combined with antipsychotic drugs on schizophrenia symptoms and cognitive improvement， providing evidence-based support for the clinical application of Wendan Decoction. MethodsLiterature searches were conducted in China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP Information， China Biomedical Literature Service System， China Clinical Trial Registry， PubMed， Web of Science， the Cochrane Library， and Embase to collect randomized controlled trials （RCTs） of modified Wendan Decoction combined with antipsychotic drugs for the treatment of schizophrenia. The search period was from the establishment of the databases to March 19， 2026. The quality of the included literature was evaluated using the Cochrane 6.3. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 11 studies were included， involving 1 130 patients with schizophrenia. Among them， 566 cases were in the study group （receiving modified Wendan Decoction combined with antipsychotic drugs）， and 564 cases were in the control group （receiving antipsychotic drugs only）. Meta-analysis showed that the effective rate of improvement in psychotic symptoms in the study group was higher than that in the control group （RR=1.21，95% CI： 1.15–1.27， P<0.01）. In terms of psychotic symptoms， the Positive and Negative Symptom Scale （PANSS） positive symptom score （MD=-3.69， 95% CI： -5.87–-1.51， P<0.01） and PANSS total score （MD=-9.20， 95% CI： -11.80–-6.59， P<0.01） of the study group were lower than those of the control group. In cognitive function assessments， the Mini-Mental State Examination （MMSE） score （MD=2.51， 95% CI： 1.33–3.68， P<0.01） and the Loewenstein Occupational Therapy Cognitive Assessment （LOTCA） score （MD=11.85， 95% CI： 2.55–21.15， P=0.010） of the study group were higher than those of the control group， and the Wisconsin Card Sorting Test （WCST） score was lower than that of the control group （MD=-9.34， 95% CI： -12.57–-6.11， P<0.01）. The levels of brain-derived neurotrophic factor （BDNF） （SMD=1.34， 95% CI： 0.63–2.05， P<0.01） and nerve growth factor （NGF） （MD=6.94， 95% CI： 4.00–9.89， P<0.01） of the study group were higher than those of the control group. In terms of safety， there was no statistically significant difference in the incidence of adverse reactions between the two groups （RR=0.60， 95% CI： 0.31–1.18， P=0.14）. ConclusionThe modified Wendan Decoction combined with antipsychotic drugs may be more effective than antipsychotic drugs alone in improving positive symptoms and cognitive function in patients with schizophrenia， and it also exerts a favorable neurotrophic regulatory effect. ［Funded by Postgraduate Education Reform and Quality Improvement Project of Henan Province （number， YJS2023AL060）； Key Scientific Research Projects of Higher Education Institutions in Henan Province （number， 24B320018， 25B310004）］

Objective To analyze the current status of dietary quality in patients with chronic atrophic gastritis (CAG), and to explore the influencing factors of dietary quality. Methods A retrospective study was conducted on 550 patients with CAG admitted to the hospital from April 2021 to April 2024. Self-made basic data questionnaire, dietary balance index (DBI), and hospital anxiety and depression scale-anxiety subscale (HADS-A) were used for investigation. Multivariate linear regression analysis was applied to analyze the influencing factors of DBI-lower bound score (LBS). Results The average score of DBI-LBS in 550 patients with CAG was (31.45±8.53) points. There were significant differences in DBI-LBS scores among CAG patients in terms of age, body mass index (BMI), Helicobacter pylori (HP) infection, marital status, drinking history, smoking history, CAG severity, HADS-A score and concurrent gastrointestinal diseases (P<0.05). Multivariate linear regression analysis of the above influencing factors indicated that BMI, smoking history, HADS-A score and CAG severity were independent influencing factors of DBI-LBS score in CAG patients (P<0.05). Conclusion The general dietary quality is not optimistic in CAG patients, showing a moderate deficiency in dietary intake. BMI, disease severity and psychological status of patients are independent factors affecting dietary quality.
