Objective To study the influence factors of infertility by analysis of semen sample and reference for clinical treat-ment.Methods 3 527 cases of semen sample were collected from Jan 2012 to Jun 2014.All samples were analysed by SQA-V analyzer and compared with 80 cases of normal semen.Results There were 358 normal samples (10.2%)and 3 169 ab-normal samples (89.8%).Among the abnormal samples low sperm motility had the highest ratio (2.7%)while abnormal pH had the lowest ratio (61.5%).All the indexes had significance difference to normal sample expect pH value (t=0.065, P =0.969).Among them,the comparison of rate had statistical significance(χ2 =3.214~24.712,P <0.05).The compari-son of mean also had statistical significance(t=2.523~15.324,P <0.05).Conclusion Infertility male almost has abnormal index of semen volume,liquefaction time,sperm motility,sperm density,sperm morphology,sperm viability.Accurately sperm analysis can provide objective basis to clinical diagnosis and treatment.

Objective:To investigate the differences in understanding and diagnosis of polycystic ovary syn-drome(PCOS)among obstetricians and gynecologists with different clinical experiences,in order to promote com-munication and improve medical quality.Methods:This was a multi-center cross-sectional survey.Information on participants'basic information and their knowledge of PCOS comorbidities and treatment management was col-lected online.Physicians were divided into two groups according to their experience:experienced(>200 consulta-tions/year)and inexperienced(≤200 consultations/year).The differences in the diagnosis and treatment of PCOS among different groups were compared.Logistic regression analysis was used to explore other factors that might influence the diagnosis and treatment of PCOS.Results:1689 questionnaires were finally included,among which 95 were experienced and 1594 were inexperienced.①In the comparison of basic conditions,the proportion of experienced persons in tertiary hospitals and reproductive endocrinology specialties was higher than that of in-experienced persons(P<0.05);The percentage of experienced persons who predicted patients with comorbid insulin resistance(proportion>30%)and predicted comorbid overweight/obesity(proportion 30%-50%)was higher than that of less experienced persons(P<0.05).②There was no significant difference in the evaluation of PCOS and its complications among different groups(P>0.05).Logistic regression suggested that different expe-riencers did not significantly affect the assessment of androgens,OGTT and lipid testing(P>0.05).③There was no statistical significance in the choice of treatment for those with no fertility need(P>0.05).For those with fertili-ty needs,metformin and letrozole were more actively selected by experienced group than inexperience(P<0.05).In terms of weight loss,experienced participants were more active in using metformin(P<0.05)and were more likely to choose1.0 or1.5 g/d(P<0.05)than those with inexperience.Conclusions:There was no signifi-cant difference in PCOS assessment among participants with different experience,but in treatment,experienced participants were better able to take into account the multi-system abnormalities brought by PCOS,and at the same time,they give more comprehensive and accurate treatment opinions on patients with or without fertility needs.

Objective To investigate the current situation of the construction of geriatrics in second and third level gen-eral hospitals in Guangxi,analyze the existing problems,and propose suggestions.Methods A self-developed"Survey on the Current Situation of Geriatrics Construction"was used to conduct a questionnaire survey on 250 second and third level general hospitals in Guangxi from April to September 2021.Results A total of 98 geriatrics were established in 196 general hospitals,and the overall number met national requirements.Among them,36 are independent institutions,including 24 tertiary hospitals and 12 secondary hospitals,with 2 172 beds and 1 764 medical staff.Conclusion In the future,Guangxi should ensure the high-quality construction of geriatrics,reasonably allocate geriatric human resources,enhance disciplinary medical service capa-bilities,strengthen overall two-way health connections,and vigorously promote the construction and development of geriatrics in Guangxi.

Objective:To explore the mediating effect of coping style on disease perception and pre-hospital delayed behavioral intention in patients with acute ischemic stroke.Methods:This study was a cross-sectional study. From February to July 2023, convenience sampling was used to select 205 patients with acute ischemic stroke admitted to the First Affiliated Hospital of Naval Medical University as the study subject. The survey was conducted using the General Information Questionnaire, Stroke Pre-Hospital Delay Behavior Intention, Brief Illness Perception Questionnaire, and Simplified Coping Style Questionnaire.Results:205 questionnaires were filled out, 195 valid questionnaires, and the validity rate of the questionnaire was 95.1%. The Stroke Pre-Hospital Delay Behavior Intention score of patients with acute ischemic stroke was (63.61±16.12). Pre-hospital delayed behavioral intention in patients with acute ischemic stroke was positively correlated with disease perception and negative coping ( r=0.360, 0.266; P<0.01), and negatively correlated with positive coping ( r=-0.279, P<0.01). The mediating effects of positive and negative coping on disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients were 0.111 and 0.097, respectively, accounting for 26.89% and 23.49% of the total effect. Conclusions:There is a partial mediating effect of coping strategies between disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients. In the process of stroke management, medical and nursing staff can reduce pre-hospital delayed behavioral intentions by improving disease cognition and coping style.
