Objective To study the value of PSADT in predicting the prognosis and the possibility of disease progression for patients with prostate cancer after MAB therapy.Methods Based on the retrospective review of the history and the follow-up of 159 prostate cancer patients,who received MAB therapy in our department from January 1994 to December 2010,PSADT values were calculated and survival analysis was performed.The ages at diagnosis ranged from 54 to 90 years with a median of 74 years.The pretreatment PSA value ranged from 2.6 to 275.0 μg/L with a median of 46.8 μg/L.The patients of Gleason score ≤6,7 and ≥8 constituted 27.7％,42.1％ and 25.2％,respectively.Only 26.4％ of the patients were staged as T1N0M0-T2N0M0 and the others had locally advanced disease or metastasis.A multivariate analysis with a Cox's proportional hazard model was used and the disease progression rates in different PSADT groups were also compared.Chi-square test and Log-rank test were applied in statistic analysis.Results The 159 patients received follow-up with a median period of 28 months (6-126 m).The median PSADT of these 159 patients was 5.7 months (0.5-21.0 m).The 3-year and 5-year survival for the 71 patients,whose PSADT were not less than 6 months,were 89.4％ and 47.6％ respectively,compared with 49.8％ and 30.6％ for the other 88 patients whose PSADT were less than 6 months.The survivals were significantly different between the two groups (P ＜ 0.01).It was confirmed by a further multivariate analysis with a Cox' s proportional hazard model that PSADT was one of the predictive factors of the prognosis of these prostate cancer patients with a hazard ratio of 2.6 (P ＜ 0.01).Moreover,disease progression were found in 19.7％ of the PSADT≥6 m group during the follow-up compared with 63.6％ in the PSADT ＜6 m group.The disease progression rates were also significantly different (P ＜ 0.0 l).Conclusions PSADT can be used to predict the prognosis of patients with prostate cancer after the MAB therapy.The survival for the patients,whose PSADT are not less than 6 months,is higher than those whose PSADT less than 6 months.Meanwhile,PSADT can predict the possibility of disease progression after MAB treatment.

Objective To investigate if distribution of stone composition and onset age in the upper urinary tract changed during the past 12 years in China.Methods There were 1 878 urolithiasis patients of the upper urinary tract in our hospital from 2003 to 2014 enrolled in present cross-sectional study.There were 1 300 male and 578 female patients with a median onset age of 46 (6-95) years.Stone composition was measured by infrared spectrophotometry.All the patients were divided into 3 groups according to the onset year:Year 2003-2006,Year 2007-2010 and Year 2011-2014.The distributions of stone types were compared among the 3 groups.Age and gender were included as potential confounders.Chi square test,P trend test,Kruskal-Wallis test and logistic regression were employed in the statistical analysis.Results Calcium oxalate was the most common type with a dominant proportion of 78.1％ (1 466/1 878),while uric acid had a small proportion of 4.8％ (91/1 878).The proportions of uric acid in the 3 groups were 2.7％ (12/441),5.1％ (39/758) and 5.9％ (40/679),showing an increasing trend (P ＜0.05).Multivariate analysis showed that year group was independently correlated with the proportion of uric acid,with an OR of 1.385 (95％ CI,1.027-1.867).From 2003 to 2014,the proportion of uric acid calculus increased by 0.42％ (95％ CI,0.25％-0.59％) annually.The median ages of disease onset were 43,46 and 49 years respectively in those three groups,also showing an increasing trend with time (P ＜0.01).Conclusion From 2003 to 2014,the proportion of uric acid and onset age in patients of upper urinary tract calculi were increased in the present cohort.

Objective To investigate the proportion , risk factors and tendency of change of stone composition in recurrent urolithiasis .Methods Eighty-five recurrent urolithiasis patients from 2002 to 2014 were enrolled in this retrospective cohort study .There were 61 male and 24 female patients with a median age of 51 (21-89) years at initial events.Among those patients, 70 had two events, 12 had three events, and 3 had more than 3 events.Compositions of initial and recurrent stones were measured by infrared spectrophotometry.Stone type, recurrence interval and recurrence frequency were studied as potential risk factors for composition change . Chi square test and logistic regression analysis were employed in the statistical analysis.Results Stone composition changed during recurrence in 26 patients ( 30.6%) . Univariate analysis showed the risk ratio of composition change in the patients with recurrence interval of 1-5 years was 0.518 (95%CI, 0.277-0.967, P<0.05) when compared with those of less than 1 year or more than 5 years.Logistic regression analysis showed the odds ratio of recurrence interval of 1-5 years was 0.231 (95%CI, 0.075-0.707, P=0.010).The mutual conversion between calcium oxalate and infection stones was mostly observed when stone composition changed during recurrence .Twenty percent of calcium oxalate stones changed to infection stones and 29.2% of infection stones changed to calcium oxalate .
Conclusions Stone composition changes in about one third patients of recurrent urolithiasis .The mutual conversion between calcium oxalate and infection stones is the most common change .Recurrence interval is an independent risk factor to predict composition change .Repeated stone analysis should be suggested to patients with recurrent interval of less than 1 year or more than 5 years.

Objective:To investigate the impact of teacher-student language interaction behavior in the teaching quality of health management courses in lecture competitions by using the Flanders interaction analysis method.Methods:The Flanders interaction analysis model was used to collect and analyze the data on teacher-student interaction behavior of three teachers during the lecture competitions of health management courses, and the three teachers were analyzed in terms of behavior in classroom interaction, student reactions, and features of interaction mode.Results:During the lecture competition, it was found that region E in the FIAS matrix was positive and qualified, and the frequency ratio of positive and qualified to defective grids was much greater than 1 for the three teachers. The teaching methods of all three teachers could alleviate the tense atmosphere in the classroom, enhance interaction between teachers and students, and improve the learning effectiveness of students. The speech behaviors of Teacher C and Teacher S were 91.87% and 81.48%, respectively, which were higher than the norm, while the speech behaviors of Teacher Y was 52.63%, which was lower than the norm. The integrated teaching method was better than the teaching methods of case-based learning and problem-based learning and could better help students master health knowledge and skills, cultivate a healthy lifestyle, promote physical and mental health, and improve health literacy.Conclusions:By using the Flanders interaction analysis method, teachers can observe and analyze interactions with students, evaluate teaching effectiveness, and provide targeted feedback and improvement suggestions to improve teaching quality and the learning outcomes of students. At the same time, teachers and students can also understand their strengths and weaknesses through observation and analysis of interaction methods and make corresponding improvements to teaching methods and contents, so as to encourage students to actively participate in classroom interaction and improve learning effectiveness and student satisfaction.

Objective:To explore the influence of points system management on the career development of medical staff in health management discipline.Methods:Using a cross-sectional study design, medical staff in the health management discipline of tertiary hospitals in China were selected as the research objects from February 1 to March 1, 2024 through questionnaire star convenience sampling and snowball sampling, and their general information, performance appraisal satisfaction, professional identity, burnout, professional benefit, professional career management and other information were collected, and the correlation and influencing factors among them were explored. A total of 423 questionnaires were distributed, and 402 (95.0%) valid questionnaires were collected.Results:A total of 207 (51.5%) medical staff had job burnout, and 257 (63.9%) of them had medium or below level of professional identity. There were positive correlations among performance appraisal satisfaction, professional identity, career benefit and professional career management. There was a negative correlation between burnout and performance appraisal satisfaction ( r=-0.439), professional identity ( r=-0.356), career benefit ( r=-0.584), and professional career management ( r=-0.185) (all P<0.05). Higher age, working time, monthly income level, title level, position level, understanding of performance appraisal system, satisfaction with feedback results and application satisfaction were the protective factors of burnout, and under the points-based system, the scores of performance appraisal satisfaction, professional identity, career benefit, and professional career management were higher, and the differences were statistically significant (all P<0.05). A total of 310 medical staff (77.1%) believed that performance appraisal had a motivating effect on them. Conclusion:The performance appraisal of the point system has a good motivating effect on the medical staff of the health management discipline, and is closely related to professional identity, burnout, professional benefit, and professional career planning.

In recent years, minimally invasive surgery has been rapidly developed and has become the first choice for the treatment of moderate to severe benign prostatic hyperplasia (BPH). Although it can significantly improve the lower urinary tract symptoms, reduce complications, and enhance security, postoperative sexual dysfunction(SD) is still common, which affects the patients’ quality of life. In this paper, we discuss the incidence rate of SD after BPH surgery, the protection strategy of sexual function, and how to choose reasonable treatment from the perspective of sexual function protection.

Objective To investigate the risk of diabetes mellitus in ABO blood type.Methods The da-ta of 1306397 healthy physical subjects in the Department of Health Management of the First Affiliated Hos-pital of Army Medical University from 2006 to 2018 were retrospectively analyzed,including gender,age, height,weight,blood glucose,blood lipid and ABO blood type.A total of 61296 subjects with both blood type and fasting blood glucose data were selected as the study population.Multivariable logistic regression was used to analyze the risk of diabetes in different ABO blood types.Results There were significant differences in gender,age and BMI distribution between the total population and the study population (P<0.05).The num-ber of patients with diabetes and prediabetes in the study population was 2649 (4.3％) and 3979 (6.5％),re-spectively.There were significant differences in the distribution of cholesterol,low-density lipoprotein choles-terol (LDL-C),diabetes and pre-diabetes among people with different blood types (P<0.05).Multivariate lo-gistic regression analysis showed that compared with type O blood,type A blood had an increased risk of dia-betes (OR=1.38,95％CI:1.02-1.86,P=0.04),while type B blood (OR=1.28,95％CI:0.93-1.77,P=0.13) and type AB blood (OR=1.33,95％CI:0.83-2.11,P=0.23) did not increase the risk of diabetes. Conclusion Early screening of type A blood population and preventive treatment and intervention can be used to reduce the incidence of diabetes.
