Objective To explore the clinical application of salpingectomy with preserving salpingum mesothelium under single-port laparoscopy and its influence on ovarian reserve function and assisted pregnancy outcome.Methods From January 2019 to January 2022,80 cases of salpingectomy in Shuangyashan Double Mine Hospital were selected and randomly divided into control group(n=40)and observation group(n=40).The control group was treated with multi-hole laparoscopic salpingectomy with salpingum mesothelium preserved,while the observation group treated with single-hole laparoscopic salpingectomy with salpingum mesothelium preserved.The operation conditions(operation time,intraoperative blood loss,exhaust time,etc.),anti-Mullerian hormone(AMH)before and one month after operation,ovarian function(basal sinus follicle count),postoperative complications,assisted pregnancy outcome and cosmetic effect were analyzed.Results The exhaust time and postoperative hospitalization time in the observation group were shorter than those in the control group,and the operation time was longer than that in the control group(P＜0.05).One month after operation,AMH in both groups decreased,and the number of sinus follicles in observation group A was lower than that in control group.The complication rate was lower than that of the control group(P＜0.05).After a one-year follow-up,there was no significant difference in ovulation rate and pregnancy rate between the two groups(P＞0.05).Follow-up for 3 months showed that the cosmetic effect of the observation group was better than that of the control group(95.00％vs 72.50％)(P＜0.05).Conclusion Single-port laparoscopic salpingectomy with salpingum mesothelium preservation is safe,cosmetic and minimally invasive,and has little adverse effect on ovarian reserve function,which is helpful for successful pregnancy assistance and worthy of clinical application and promotion.

Objective: To explore the facilitators and barriers of the implementation of evidence based mental health practice, in order to provide practical experience for promoting the development of evidence based mental health services in primary schools in China. Methods: Semi structured interviews were conducted with 4 education bureau managers, 8 school administrators, 7 classroom teachers, and 7 treatment providers after providing evidence based practice in 10 primary schools in Henan Province, China. Data was analyzed using thematic analysis. Results: Evidence based practice in primary schools faced multiple factors at the macro level, school level, and individual level. A total of 8 facilitators and 9 barriers were extracted. Among these factors, some factors were particularly striking. These included the "exclusion" of teacher title evaluation system, time conflict between practice and school schedule, stigmatization of mental health and mismatch between perceived effectiveness of services and expectations. Conclusion Evidence based mental health practice is feasible in Chinese schools. The implementation process needs to take full account of macro, school and individual multi level factors to move evidence based mental health services from theory and data to practice in China.

Objective: To explore the relationships between the characteristics of childhood sexual abuse and non-suicidal self-injury in nursing female college students. Methods: Two medical colleges and junior colleges were selected in Anhui province. A total of 2 549 female nursing students in grade 1 to 3 were asked to fill a questionnaire regarding sociodemographic information,childhood sexual abuse and non-suicidal self-injury. Results: The reported rate of non-suicidal self-injury among female nursing students in the past six months was 8.2%. Sexual abuse at any time during childhood (primary school or earlier,middle school and high school) increased the risk of non-suicidal self-injury among female nursing students (P<0.05). Exposure to sexual abuse in all three periods was associated with 5.04(95%CI=1.73-14.62) times odds ratio than that of those who not exposed to sexual abuse (P<0.01). Only contact sexual abuse and both contact and non-contact sexual abuse in childhood were correlated with nonsuicidal selfinjury among female nursing students [OR(95%CI)=2.21(1.48-3.29), 3.56(2.13-5.96)] (P<0.05). Two patterns of sexual abuse experiences were identified,including persistent sexual abuse (3.1%) and the other group is occasional sexual (96.9%). Persistent sexual abuse in childhood was correlated to higher risk of non-suicidal self-injury compared with occasional sexual abuse (OR=2.61,95%CI=1.35-5.05,P<0.01). Conclusion The occurrence periods,types and patterns of sexual abuse in childhood are closely related to non-suicidal self-injury in female nursing students.
