OBJECTIVE To investigate the influence of CYP2C19 gene polymorphism on platelet function and inflammatory cytokines in elderly patients with ischemic stroke, and to analyze potential factors associated with poor prognosis. METHODS A retrospective study was conducted on elderly patients with ischemic stroke admitted to our hospital from June 2024 to June 2025, wh o underwent CYP2C19 genotype testing and received antiplatelet therapy with clopidogrel. The levels of platelet function indicators and inflammatory cytokines before and after treatment were compared among patients with different metabolic phenotypes. Based on the prognosis at 6 months post-treatment, patients were divided into poor prognosis group and good prognosis group. Univariate analysis was performed on general data, metabolic phenotype, the levels of platelet function indicators and inflammatory cytokines. Variables with P <0.05 and the levels of inflammatory cytokines before treatment were included in a multivariate Logistic regression analysis to identify independent risk factors for poor prognosis. Multiple linear regression was used to further analyze the relationship between metabolic phenotypes and inflammatory cytokines. RESULTS A total of 448 elderly patients with ischemic stroke were included; among them, 162 cases were normal metabolic phenotype, 218 were intermediate metabolic phenotype, and 68 were poor metabolic phenotype. No rapid or ultrarapid metabolic phenotypes were observed. After treatment, platelet aggregation rate, the levels of P-selectin and platelet activated complex-1 (PAC-1), high-sensitivity C-reactive Protein (hs-CRP), interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) in the normal metabolic phenotype group, intermediate metabolic phenotype group, and poor metabolic phenotype group (except for platelet aggregation rate, and the levels of P-selectin and PAC-1 in the poor metabolic phenotype group) were significantly lower than those before treatment in the same group. Moreover, the above indicators in the normal metabolic phenotype group were significantly lower than those in the intermediate and poor metabolic phenotype groups at the corresponding time, and the levels of platelet function indicators in the intermediate metabolic phenotype group were significantly lower than those in the poor metabol ic phenotype group at the corresponding time ( P <0.05). Univariate and multivariate Logistic regression analyses showed that combined with hypertension, combined with diabetes mellitus, and intermediate or poor metabolic genotypes were independent risk factors for poor prognosis in elderly patients with ischemic stroke ( P <0.05). Multiple linear regression analysis showed that serum levels of hs-CRP, IL-1β, IL-6 and TNF-α before treatment were significantly higher in patients with intermediate and poor metabolic genotypes compared to those with normal metabolic genotype ( P <0.05), with a greater magnitude of increase in inflammatory cytokines observed in the patients with poor metabolic genotype. CONCLUSIONS The elderly ischemic stroke patients with CYP2C19 intermediate and poor metabolic genotypes have poor inhibition effect on platelet and higher levels of inflammatory cytokines than normal metabolic genotype; CYP2C19 gene polymorphism, and in combination with hypertension and diabetes, can be used as independent predictors of poor prognosis.

Lipid rafts are microdomains in the cell membrane that are involved in cell signal transduction,metabolism,and intercellu-lar interactions.In recent years,studies have shown that lipid rafts play an important role in the pathogenesis of diabetes.Cholesterol and sphingolipids are the main lipid components in lipid rafts,and the protein components in lipid rafts include caveolin,flotillin,pal-mitoylated proteins,and glycosylphosphatidylinositol-anchored proteins.Changes in these components affect the structure and function of lipid rafts,which in turn may affect insulin signal transduction,leading to the occurrence of diabetes-related diseases.Lipid rafts are closely related to the occurrence and development of diabetes in different tissues.Pancreatic lipid rafts are closely related to insulin se-cretion,and their structural changes affect insulin synthesis and release.Changes in lipid rafts in adipose tissue are related to insulin resistance and disorders of glycolipid metabolism.Changes in lipid rafts in the liver can affect gluconeogenesis and glycogen synthesis.Lipid rafts in the kidney play a regulatory role in the progression of diabetic nephropathy.This article aims to provide a comprehensive overview of the role of lipid rafts in the pathogenesis of diabetes,offering insights into the identification of new targets for the prevention and treatment of diabetes in the future,as well as presenting a new perspective for the development of therapeutic agents for diabetes.

OBJECTIVE To analyze the correlation of the peak blood concentration (cmax) of compound sulfamethoxazole (TMP/SMZ) and its metabolite N-acetyl sulfamethoxazole (NSMZ) with clinical efficacy and adverse reactions in critically ill patients. METHODS The data of critically ill patients treated with TMP/SMZ in various ICU of Hainan General Hospital from December 2023 to January 2025 were retrospectively collected. The patients were divided into success group and failure group based on the treatment outcome. Simple linear regression and Spearman correlation analysis were used to analyze the correlation of TMP cmax, SMZ cmax, and NSMZ cmax with clinical efficacy and adverse reactions. The receiver operating characteristic curve (ROC) was used to determine the cutoff values of cmax for predicting the occurrence of adverse reactions. RESULTS Among critically ill patients with an acute physiology and chronic health evaluation Ⅱ (APACHE-Ⅱ) ≥15 points 24 h of check-in at ICU, SMZ cmax of success group was significantly higher than failure group (P<0.05). The daily total dose of TMP/SMZ was positively correlated with TMP cmax and SMZ cmax( P<0.05). TMP cmax was significantly correlated with hepatotoxicity and nephrotoxicity, SMZ cmax with hepatotoxicity, and NSMZ cmax with nephrotoxicity (P<0.05). The cutoff values of TMP cmax for predicting nephrotoxicity and hepatotoxicity were 7.25 μg/mL and 6.63 μg/mL, respectively. The cutoff value of SMZ cmax for predicting hepatotoxicity was 138.00 μg/mL, and that of NSMZ cmax for predicting nephrotoxicity was 60.76 μg/mL. CONCLUSIONS Among critically ill patients with an APACHE-Ⅱ ≥15 points 24 h of check-in at ICU, SMZ cmax is associated with treatment success. Hepatotoxicity risk significantly increases when TMP cmax ≥6.63 μg/mL or SMZ cmax ≥138.00 μg/mL; nephrotoxicity risk significantly increases when TMP cmax ≥7.25 μg/mL or NSMZ cmax ≥60.76 μg/mL.

Polycystic ovary syndrome (PCOS) is a common gynecological endocrine and reproductive disorder,with the main clinical manifestations including ovulation failure,insulin resistance,hyperandrogenism,and obesity. Its occurrence and development are closely related to cellular regulatory mechanisms such as apoptosis,autophagy,oxidative stress,and inflammatory response. Autophagy,as a clearance mechanism that maintains cellular homeostasis,plays a crucial role in maintaining the growth,development,and maturation of oocytes. Exploring the mechanism of autophagy during the occurrence and development of diseases can help develop treatment methods for PCOS by regulating autophagy. Studies have shown that autophagy plays an important role in the pathogenesis of PCOS,and it can affect the occurrence and development of PCOS through multiple pathways,levels,and targets. Traditional Chinese medicine (TCM) regulates autophagy in ovarian granulosa cells or endometrium of patients with PCOS by targeting the expression of autophagy signaling pathways,regulatory factors,and non-coding single-stranded RNA molecules,thereby alleviating inflammation,regulating metabolism disorders,and balancing hormone levels in PCOS. Accordingly,TCM can ameliorate pathological conditions such as insulin resistance,hyperandrogenism,and ovulation failure in PCOS. This article summarizes the TCM formulas and extracts for the treatment of PCOS,as well as the main autophagy pathways and regulatory factors involved,aiming to provide reference and suggestions for the future treatment of PCOS with TCM by regulating autophagy.

Objective:To explore the dual mediating effects of health belief and depression among health knowledge, social support, and health behaviors based on the capacity, opportunity, motivation-behavior (COM-B) model, and analyze the influencing factors of health behaviors in patients with ischemic stroke.Methods:This multi-center cluster sampling research recruited ischemic stroke patients ( n=1 696) who were hospitalized in neurology departments of five tertiary hospitals in Henan Province from October 2023 to October 2024. A cross-sectional investigation was conducted using the general information questionnaire, social support rating scale (SSRS), stroke prevention knowledge questionnaire(SPKQ), short form health belief model scale(SF-HBMS), health promoting lifestyle profile-Ⅱ (HPLP-Ⅱ), and patient health questionnaire-9(PHQ-9) to ultimately reveal the pathways and effect sizes among variables. Partial correlation analysis and multiple linear stepwise regression analysis were conducted to examine the relationships among social support, health knowledge, health belief, health behaviors, and depression in stroke patients by SPSS 26.0 software. Structural equation modeling was constructed using AMOS 28.0 software, and the mediating effect was tested using the Bootstrap method. Results:The scores of social support, health knowledge, health belief, and health behaviors among ischemic stroke patients were (37.46±9.94), (26.56±6.84), (75.62±12.62) and (130.79±26.27), respectively. The score of depression was 5.00 (2.00, 8.00). Health behaviors were positively correlated with health knowledge, social support, and health belief( r=0.333, 0.246, 0.267, all P<0.05), while negatively correlated with depression ( r=-0.146, P<0.05). Multiple linear stepwise regression analysis showed that health knowledge, social support, health belief, and depression were all influencing factors of health behaviors in ischemic stroke patients (all P<0.05). Health belief (effect value=0.068, 95% CI=0.048-0.093) and depression (effect value=0.009, 95% CI=0.003-0.018) both played partial mediating roles between health knowledge and health behaviors, accounting for 17.3%(0.077/0.446) of the total effect. Meanwhile, health belief (effect value=0.045, 95% CI=0.029-0.063) and depression (effect value=0.016, 95% CI=0.008-0.027) both played partial mediating roles between social support and health behaviors, accounting for 26.5%(0.061/0.230) of the total effect. Conclusion:Health knowledge and social support can not only directly influence health behaviors but also indirectly affect them through health belief and depression in patients with ischemic stroke.
