Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

Objective To explore the experiences of master degree nursing students and their supervisors under the dual-supervisor system.Methods A phenomenological research was adopted in this study eighteen master degree nursing students,five principle supervisors and four assistant supervisors from our university were selected through purposive sampling for semi-structured interviews between July and September 2023.Data acquired from the interviews was analysed using Colaizzi's method to summarise and extract the themes.Results Three main themes and eleven sub-themes were extracted,including the collaborative framework of the dual-mentor system(discrepancies in the perception of the dual-mentor system between faculty and students,the selection and matching process for associate mentors,the division of responsibilities and collaborative dynamics between primary and associate mentors,student-centered personalized training strategies,context-specific guidance provided by associate mentors,and the extent to which inter-role communication relies on student initiative),the benefits of the dual-mentor system(encompassing diversified academic and professional guidance,as well as integrated theoretical and practical support)and the expectations held by faculty and students regarding the dual-mentor system(refining institutional design and reinforcing accountability,enhancing the support infrastructure for associate mentors,and improving the tripartite communication mechanism among faculty,students,and associate mentors).Conclusion In nursing postgraduate education,the roles and responsibilities within the dual-mentor system can be more clearly delineated,and inter-mentor collaboration should be further strengthened.It is recommended to enhance tripartite communication among faculty,students,and associate mentors to foster the effective implementation and development of the dual-mentor system.

Experimental teaching is an important component of the course Medical Immunology,which requires the use of experimental animals and the execution of experimental animals by medical students.By applying the carbon dioxide euthanasia system,it can effectively reduce the pain of experimental animals,ensure their welfare,and meet ethical requirements.It can also improve the efficiency of experimental teaching in Medical Immunology,reduce environmental pollution,and promote medical students to estab-lish scientific values and worldviews that pay attention to experimental animals and respect life,which is conducive to becoming future medical service talents.In the experimental teaching of Medical Immunology,the appropriate application of carbon dioxide euthanasia system combined with effective ideological and political construction of the curriculum can further implement the Party's educational policy of cultivating morality and talents,and lay a good foundation for cultivating medical talents with comprehensive knowledge,high skills and excellent quality.

Objective:To explore the prognostic value of peripheral blood lymphocyte subsets in lymphoma patients with different infection status of Epstein-Barr virus (EBV).Methods:A retrospective cohort study. A total of 333 lymphoma patients newly diagnosed from November 2012 to August 2023 in the Affiliated Hospital of Xuzhou Medical University were included in the study, including 185 patients with Diffuse Large B-cell Lymphoma (DLBCL), 100 patients with Natural Killer/T-cell Lymphoma (NKTCL), and 48 patients with Hodgkin Lymphoma (HL). Clinical data and laboratory indicators of patients were collected, including lymphocyte subset ratios detected by flow cytometry and EBV-DNA levels measured by real-time quantitative polymerase chain reaction. The survival status of patients was recorded through referring to medical records and telephone follow-up. The Kaplan-Meier method was used to plot survival curves and compare the survival rates among different groups. The Cox proportional hazards model was applied to analyze factors related to overall survival in lymphoma patients.Results:In the NKTCL group, 73.0% (73/100) were positive for EBV-DNA, which was higher than 43.8% (81/185) in the DLBCL group and 35.4% (17/48) in the HL group ( P<0.001). Kaplan-Meier survival curves showed that lower overall survival rates in the DLBCL group with abnormal levels of CD19 +B cells and CD16 +CD56 +NK cells (defined as either high or low referring to the reference intervals), with EBV-DNA negative and abnormal levels of CD19 +B cells, or with EBV-DNA positive and abnormal levels of CD16 +CD56 +NK cells, compared with the normal level group ( P<0.05). Multivariable analysis suggested that the abnormal level of CD19 +B cells was an independent adverse prognostic factor for DLBCL patients ( HR=2.098, 95% CI 1.181-3.727, P=0.011). EBV-DNA positivity ( HR=17.623, 95% CI 2.397-129.565, P=0.048) and Ann Arbor stage (Ⅲ/Ⅳ) ( HR=2.770, 95% CI 1.335-5.750, P=0.006) were adverse prognostic factors for NKTCL patients. Conclusion:There are differences in peripheral blood lymphocyte subsets among lymphoma patients with different EBV infection status, and CD19 +B cell levels may serve as an independent prognostic factor for DLBCL patients.

Objective:To revise the Chinese version of the Coparenting Inventory for Parents and Adolescents(CI-PA)in middle school students and their parents to test the validity and reliability.Methods:Totally 691 middle school students were tested with the adolescent version of CI-PA,924 parents were tested with the parents'version of CI-PA.The sample was split randomly in half,and item analysis and exploratory factor analysis,confirmatory factor analysis,criterion validity analysis and convergent validity test were performed respectively.The Achenbach Youth Self-Report(YSR)and marital satisfaction subscale(MSS)of Olson Enrich Marital Inventory(ENRICH)were used to test the validity of the criterion.Totally 62 students and 70 parents were followed to complete the Chi-nese version of CI-PA 4 weeks after the first investigation.Results:Exploratory factor analysis showed that there were 37 and 25 items in the adolescent version and the parents'version respectively,3 factors were extracted,inclu-ding 3 dimensions of cooperation,triangulation and conflict.The factor loadings of each item ranged from 0.60 to 0.95,and the subscales explained the total variance ranged from 64.56％to 74.06％.Confirmatory factor analysis showed that all the 3 factors models fitted well in adolescent version(x2/df=1.32,1.30,1.41;CFI=0.99,0.99,0.99;TLI=0.99,0.99,0.98;RMSEA=0.03,0.03,0.03)and the parents'version(x2/df=1.20,1.33;CFI=0.99,0.99;TLI=0.99,0.99;RMSEA=0.02,0.03).Cooperation scores of the adolescent version were negatively correlated with the YSR scores(ICC=-0.18--0.27,Ps＜0.01),triangulation and conflict scores of the adoles-cent version were positively correlated with the YSR scores(ICC=0.15-0.34,Ps＜0.01).Cooperation scores of the parents'version were positively correlated with the MSS scores(ICC=0.52,0.47,Ps＜0.01),triangulation and conflict scores of the parents'version were negatively correlated with the MSS scores(ICC=-0.28--0.47,Ps＜0.01).The Cronbach's α of 3 dimensions were all above 0.72,the retest reliabilities(ICC)were all a-bove 0.54.Conclusion:The Chinese version of Coparenting Inventory for Parents and Adolescents(CI-PA)is valid and reliable in measuring the coparenting in Chinese adolescence families.
