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.

AIM:To automatically identify and quantitatively assess myopia-related fundus structural changes by combining non-mydriatic color fundus photography with an artificial intelligence(AI)-powered quantitative fundus analysis system and to further analyze the correlations between these fundus parameters and spherical equivalent(SE), axial length(AL), and age, providing the objective basis for monitoring myopia progression and supporting the formulation of personalized myopia prevention and control strategies. METHODS:A cross-sectional study was conducted enrolling myopic patients aged 18-50 y who underwent myopia screening from March 2023 to December 2023. Patients were stratified into three groups based on SE: the -3.00 D

BACKGROUND:Studies have shown that ischemia-induced cellular autophagy dysfunction is a key factor in brain injury.Autophagy related genes 6(ATG6),microtubule-associated protein 1 light chain(LC3),p62,and other autophagy key proteins are involved in the processes such as neuronal axonal degeneration,death,and intracellular homeostasis maintenance,playing an important role in the recovery of neural function. OBJECTIVE:To review the research progress in the role of cellular autophagy in cerebral ischemic injury and the regulatory mechanism of traditional Chinese medicine. METHODS:The first author used"ischemic stroke,brain tissue injury,cellular autophagy,signaling pathways,traditional Chinese medicine compounds,terpenoids,alkaloids,flavonoids,saponins,lignans,phthalates"as Chinese and English keywords respectively to search for literature on autophagy,cerebral ischemic injury,and the regulatory mechanisms of traditional Chinese medicine from China National Knowledge Infrastructure(CNKI)and PubMed databases from January 2016 to February 2024.Literature that is not highly relevant,repetitive,or outdated was excluded.A total of 1 746 relevant literature were retrieved,and 92 articles were ultimately included. RESULTS AND CONCLUSION:Numerous studies have confirmed that autophagy plays an important role in cerebral ischemic injury.Moderate autophagy can promote cell survival,while excessive autophagy exacerbates brain injury.Traditional Chinese medicine can regulate the expression of autophagy related proteins,inhibit neuronal necrosis and apoptosis,and exert neuroprotective effects at different stages of cerebral ischemia by regulating signaling pathways such as PI3K/Akt/mTOR,AMPK-mTOR,and mitogen activated protein kinase.

Objective:To explore the potential profile categories of self-disgust in young and middle-aged breast cancer patients, and analyze the influencing factors of different categories.Methods:A convenience sampling method was used, and 270 young and middle-aged breast cancer patients admitted to the thyroid and breast cancer ward and oncology ward of Fenyang Hospital in Shanxi Province from September 2023 to April 2024 were the study subjects. The survey was conducted transect surveys using the general information questionnaire, Questionnaire for the Assessment of Self-Disgust, Social Constraints Scale, the Chronic Illness Rejection and Discrimination Scale. Potential categories of self-disgust in young and middle-aged breast cancer patients were explored using latent profile analysis, and unordered multinomial Logistic regression was employed to investigate their influencing factors.Results:A total of 234 young and middle-aged female breast cancer patients were included, with the age of (45.61±10.90) years old. Latent profile analysis revealed three potential categories of self-hatred in these patients: low disgust group (45.30%, 106/234), medium disgust group (41.45%, 97/234), and generalized high disgust group (13.25%, 31/234). Compared to the low disgust group, patients with more comorbidities and poorer self-care ability were more likely to belong to the generalized high disgust group ( OR=0.244, 8.775, both P<0.05). Patients with a longer duration of illness and higher scores on the social constraints scale and chronic illness rejection and discrimination scale were more likely to fall into the medium disgust group and the generalized high disgust group ( OR values were 0.156 - 1.317, all P<0.05). Conclusions:The level of self-disgust in young and middle-aged breast cancer patients is significantly heterogeneous. Nursing staff should formulate personalized intervention strategies according to this classification characteristic, which can be cut from the perspective of reducing patients' social restriction and chronic illness rejection and discrimination to improve patients' acceptance of the disease and self-acceptance level, and then reduce their self-disgust.

Objective To analyze the clinical manifestations and genetic etiology of three families with hereditary spastic paraplegia(HSP).Methods Gene analysis was performed on patients of the three HSP families from the Gansu Provincial Maternity and Child-care Hospital.Results The proband of family 1 was autosomal recessive spastic paraplegia type 35 caused by homozygous variant c.159_176delGGCGGGCCAGGACATCAG(p.Arg53_Ser59delinsSer)in FA2H.The proband in family 2 was autosomal recessive spastic paraplegia type 47 caused by homozygous variant c.1399G>T(p.Glu467Ter)in AP4B1,and the proband in family 3 was autosomal recessive spastic paraplegia type 11 caused by homozygous variation c.7023C>G(p.Tyr2341Ter)in SPG11.Among them,the variant c.1399G>T(p.Glu467Ter)of AP4B1 is a novel variant,that has not been reported before,according to the ACMG guidelines,the pathogenicity of this variant is pathogenic.Conclusion This study has expanded the variant spectrum of AP4B1 which provides basic data to improve clinical understanding and diagnostic capabilities of HSP patients.

Objective To investigate the impact of high-frequency repetitive transcranial magnetic stimula-tion(rTMS)combined with biofeedback-assisted dry swallowing training on treating dysphagia following a stroke.Methods A total of 152 patients with dysphagia after stroke,admitted to the hospital from January 2022 to January 2024,were randomly divided into four groups using a random number table,with 38 cases in each group.The biofeedback group received biofeedback-assisted dry swallowing training,the magnetic stimulation group received high-frequency rTMS on the unaffected side,the combined group received both biofeedback-assisted dry swallowing training and high-frequency rTMS on the unaffected side,and the placebo group received conventional swallowing training and sham rTMS.All interventions lasted for 4 weeks.Clinical efficacy was recorded,and pre-and post-treatment assessments of the upper esophageal sphincter(UES)opening time,opening degree,and pharyngeal contraction duration were performed using multifunctional esophageal manometry.Additionally,swallowing func-tion,nutritional status,neurological function,and quality of life were compared.Results The clinical efficacy of the combined group was higher than that of the biofeedback and magnetic stimulation groups.Post-treatment UES opening time,opening degree,and pharyngeal contraction duration were(205.33±29.01)ms,(1.14±0.34)cm,and(559.19±63.48)ms,respectively,which were significantly better than those in the other 3 groups(P<0.05).The swallowing function scores of the combined group were(6.04±0.83)and(20.03±3.26)points,and significant improvements were observed in swallowing function,nutritional status,neurological function,and quality of life(P<0.05).Conclusion High-frequency rTMS combined with biofeedback-based dry swallowing training signifi-cantly improves the efficacy in the treatment of dysphagia after stroke.

Objective:To evaluate the progress and trends in perioperative management of postoperative delirium(POD)in the elderly over the past decade,providing insights for future research in China.Methods:Literature related to perioperative management of POD in elderly patients was retrieved from the Web of Science database published from Jan 1,2014,to Dec 31,2023.Articles and reviews were selected,and CiteSpace 6.3.1 software was used for duplicate removal and comprehensive analysis.Results:A total of 655 relevant publications were included,showing an overall increasing trend in annual output.China contributed 147 publications(22.44%,147/655),while the United States produced 134 publications(20.46%,134/655).Research hotspots focused on"hip fracture","neurocognitive disorders","Alzheimer's disease",and"oxidative stress".Conclusions:Research on the prevention and treatment of POD in elderly patients is growing globally.Although China has produced a substantial number of publications,its academic influence remains relatively limited.While clinical studies have elucidated strategies for POD prevention and treatment,further research is needed to validate intervention efficacy and explore underlying mechanisms.

To construct a recombinant fowl adenovirus 4(FAdV-4)expressing the Cap protein of goose astrovirus genotype 2(GoAstV-2),the expression cassette of Cap gene was inserted into the natural 1 966 bp deletion region of the FAdV-4 genome in the infectious clone p15A-cm-FAdV4-HNJZ.The resulted recombinant plasmid p15A-cm-FAdV4-HNJZ-Cap/GoAstV-2 was linearized with restriction enzyme and transfected into chicken hepatoma cell line(LMH)to rescue the recombinant FAdV-4 expressing the Cap protein of GoAstV-2,rF Ad V4-Cap/GoAstV-2.After 15 passages in LMH cells,the recombinant rFAdV4-Cap/GoAstV-2 was identified by PCR using primers flanking the insertion site of the Cap gene expression cassette and using viral genome DNA extracted from rFAdV4-Cap/GoAstV-2 infected LMH cells as template.LMH cells were in-fected with 15th passage rFAdV4-Cap/GoAstV-2 and indirect immunofluorescence was performed with a polyclonal antibody against Cap protein as the primary antibody.Western blot was carried out with lysates of rFAdV4-Cap/GoAstV-2 infected LMH cells.The in vitro replication dynamic of the 15th passage of the rFAdV4-Cap/GoAstV-2 was also investigated in LMH cells.The results demonstrated that the Cap gene of GoAstV-2 was presented in the genome of the recombinant vi-rus rF AdV4-Cap/Go Ast V-2,and could be expressed stably.The prepared recombinant virus in this study will lay a foundation for developing inactivated bivalent vaccine candidate against co-in-fection of FAdV-4 and GoAstV-2 in goose.

Objective To explore the application value of three-dimensional T1-weighted multi-echo DIXON(3D-T1W-mDIXON)with three-dimensional T2-weighted driven imaging with variable excitation(3D-T2W-DRIVE)in unilateral vascular compressive hemifacial spasm(HFS),and to improve the accuracy of preoperative imaging diagnosis of microvascular decompression(MVD).Methods The clinical and imaging data of 235 patients with unilateral vascular compressive HFS treated with MVD from July 2018 to August 2024 in Xuzhou City Hospital of Traditional Chinese Medicine were analyzed retrospectively.Before MVD,3D-T1W-mDIXON and 3D-T2W-DRIVE sequence image,multiplanar reconstruction were used to analyze the spatial walking relationship between facial nerve and offending vessels.The differences between the affected side and the healthy side were compared,and then compared with the MVD;By using paired chi square test,image result of 3D-T1W-mDIXON combined with 3D-T2W-DRIVE sequence with either sequence alone were compared to evaluate the superiority of two combined sequences in the diagnosis of vascular compressive HFS.Results Among 235 cases HFS on the affected side,there were 149 cases of vascular compression and 68 cases with specific neurovascular contacts,and 15 cases with dubious contacts,with a positive rate of 92.34％;In the 235 cases HFS of the healthy side,there were 21 cases of vascular compression and 25 cases with specific neurovascular contacts,and 77 cases with dubious contacts,with a positive rate of 19.57％.By using the findings during facial nerve MVD procedure as the gold standard,the positive rate of diagnosing HFS using 3D-T1W-mDIXON combined with 3D-T2W-DRIVE sequence was 92.34％.The ability of 3D-T1W-mDIXON combined with 3D-T2W-DRIVE sequence to identify offending vessels(92.34％)is superior to using 3D-T1W-mDIXON sequence alone(83.00％,x2=9.52,P＜0.05)or using 3D-T2W-DRIVE sequence alone(86.38％,x2=4.30,P＜0.05).Conclusion 3D-T1W-mDIXON combined with 3D-T2W-DRIVE sequence image can clearly show the relationship between facial nerve and peripheral blood vessels,and the diagnostic efficacy is higher than that of any sequence alone,can provide better imaging evidence for clinical diagnosis and treatment of HFS.
