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.

Objective: To develop a convenient, direct, and highly sensitive method for screening trace chemical additives in complex Chinese patent medicines, thereby addressing core technological bottlenecks in pharmaceutical analysis and quality control. Methods: A brush ionization probe device was independently designed and constructed, and an efficient detection method was established through systematic optimization of key parameters. Twenty-three Chinese patent medicine samples, representing 6 dosage forms (capsules, tablets, pills, granules, powders, and liquid preparations), were analyzed using 10 common chemical additives as target analytes. Results: All samples were successfully analyzed without complex pretreatment, and 5 chemical additives were detected in 7 Chinese patent medicines. The brush ionization probe device exhibited cost-effectiveness (~0.2 USD per probe), operational simplicity, rapid analysis (~10s per sample), high efficiency, and minimal reagent consumption (~10 μL per sample). Conclusion: This advancement is expected to provide an innovative scientific tool for improving the generality and convenience of on-site quality control, while promoting technological progress in disciplines such as pharmacology and traditional Chinese medicine.

The incidence of apoplexy remains persistently high among the older population.Based on the traditional Chinese medicine principle of"treating the elderly by focusing on the fu",this paper explores the holistic connotation of"fu".It proposes that the onset of apoplexy in the elderly is characterized by obstruction,stagnation,depression,and sluggishness,which should be treated from six fu viscera,xuanfu,and collaterals.The interconnected hierarchical network of these three systems,serving as macro-and micro-channels for qi and fluid metabolism,plays a central role in both disease development and treatment.The failure of the six fu viscera to descend and the upward invasion of turbid yin are identified as prerequisites for apoplexy onset,whereas yang qi stagnation and xuanfu blockage act as key pathogenic drivers,and the core mechanisms involve phlegm-stasis-toxin accumulation,and dysfunction of the collaterals and fu.In the treatment,acute phase requires unblocking fu viscera and restoring xuanfu patency;chronic phase focuses on dredging collaterals and opening xuanfu;and recovery phase emphasizes tonifying combined with regulating xuanfu.The understanding of"treating the elderly by focusing on the fu"emphasizes that the pathogenesis of the disease should be changed to individual conditions;"six fu viscera-xuanfu-collaterals"exhibits a pathological mechanism characterized by the transmission and reception of pathogenic factors,as well as progressive mutual involvement;in clinical practice,treatment should meticulously assess the severity and nuances of the condition,prioritizing method that emphasizes unobstructed flow;additionally,therapy should be essential to protect stomach qi and integrate therapeutic attacks within a framework of supplementation.These principles offer valuable reference for the differentiation and treatment of apoplexy.

Objective To observe the mid-and long-term effects of Kegel training combined with Pilates training on urinary conti-nence recovery in different body mass index(BMI)male patients with urinary incontinence after prostatectomy.Methods From May,2023 to June,2024,48 patients in Beijing Bo'ai Hospital were recruited and divided into group A(<25 kg/m2,n=15),group B(25 to 30 kg/m2,n=18)and group C(>30 kg/m2,n=15)according to their BMI.All the groups performed Kegel training combined with Pilates training for two months,and followed up at six months from baseline.They were evaluated with one hour pad test,the number of daily urinary incontinence,In-ternational Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF)and modified Oxford Rating Scale before treatment,and four weeks,eight weeks and six months after treatment.Results The intra-group effect,the inter-group effect and interaction effect were significant in the results of one hour pad test and the daily number of urinary incontinence(F>2.955,P<0.05).Post Hoc test showed that they were worse in group C than in groups A and B(P<0.05),and the number of daily urinary incontinence was more in group B than in group A(P<0.05).There was significant difference in the scores of ICIQ-SF and modified Ox-ford Rating Scale among groups in different time points after treatment(Z>10.476,P<0.05)except the score of ICIQ-SF four weeks after treatment(P>0.05),and they were the worst in group C.BMI(group A=1,group B=2,group C=3)was correlated with the results of one hour pad test(r=0.79,P<0.001),the number of daily uri-nary incontinence(r=0.68,P<0.001),and the scores of ICIQ-SF(r=0.68,P<0.001)and modified Oxford Rating Scale(r=-0.47,P=0.001)six months after treatment.Conclusion Kegel training combined with Pilates training could improve the urinary control in patients with urinary in-continence after prostatectomy.The decrease of BMI can promote the recovery of urinary control,and improve the symptoms of later urinary incontinence in mid-and long-term.

A young male patient was diagnosed with aplastic anemia accompanied by paroxysmal nocturnal hemoglobinuria(PNH),and achieved only partial remission after immunosuppressive therapy.Over the past year,his anemia worsened,leading to transfusion dependence,which was considered to be caused by active he-molysis of PNH.Despite switching to eculizumab treatment,his anemia continued to deteriorate.A detailed medical history revealed chronic periodontal infection,with periodontal pain,purulent discharge,and fever in the past month.Multidisciplinary discussion suggested that chronic odontogenic infection activating the comple-ment system was the primary cause of aggravated PNH hemolysis,and the acute infection affected the efficacy of eculizumab.Based on multidisciplinary consultation,a treatment plan was formulated,including intravenous antibiotics combined with periodontal irrigation and tooth extraction to control odontogenic infection,while con-tinuing regular eculizumab infusion.The patient's symptoms improved,hemoglobin levels rose rapidly,and he was no longer transfusion-dependent.This case provides an empirical reference for addressing difficulties en-countered in the treatment of rare diseases with new drugs through multidisciplinary collaborative diagnosis and treatment.
