Objective To evaluate clinical outcome and complications of mesh-augmented vaginal reconstructive surgery in treatment of pelvic organ prolapse. Methods From Feb 2007 to Jan 2009, meshaugmented vaginal reconstructive surgery were performed on 66 women with pelvic organ prolapse stage Ⅲ-Ⅳ. Pre and postoperative symptoms, pelvic organ prolapse quantitation (POP-Q) stage and pelvic floor distress inventory-short form 20 (PFDI-20) measurements were studied to assess anatomic and quality-of-life outcome. Operative complications were also analyzed. Results Totally 65 patients underwent successful surgeries. The rate of follow-up was 97% (63/65) with a median follow-up of 17. 2 months. Subjective cure rate and objective cure rate were both 97% (61/63) at 6 and 12 months after surgeries, 51 women completed PFDI-20 measurements and scores were 102 ± 50 before surgery, 16 ± 21 at 6 months and 15 ± 20 at 12 months. It reached statistical difference when scores were compared before and after surgeries ( P ＜0. 05). Among 66 patients, 2 patients underwent organ injuries, 2 had recurrent prolapse, 4 had meshrelated complications and 1 had severe de novo stress urinary incontinence. Six patients underwent second surgery. Conclusions Mesh-augmented vaginal reconstructive surgery in treatment of pelvic organ prolapsed brought satisfied clinical outcome. The incidence of mesh-related complications was low and secondary operative interventions were effective.

Objective:To investigate the situation of continuing medical education (CME) among obstetricians and gynecologists from Beijing's general hospitals at the secondary level or above in 2018 and 2023, and to provide a reference for standardizing CME for obstetricians and gynecologists in the future.Methods:We performed questionnaire surveys and interviews with 164 obstetricians and gynecologists in Beijing to investigate the status of completion of CME, the reasons for incompletion, the preferred modes to complete CME, and the preferred contents and forms of CME. SPSS 26.0 software was used for data analysis. The rate was compared using the chi-squared test.Results:Due to the impact of coronavirus disease 2019, the 2023 survey showed that 79 (48.17%) participants completed CME in an online mode, and 76 (46.34%) participants completed CME in an mostly online mode, with a significantly increased degree of satisfaction with CME compared with the 2018 survey ( P<0.05); 49 (29.88%) participants believe that online education is superior to traditional CME, and 69 (42.07%) participants believe that online education is comparable to traditional CME. The main advantages of the online education mode are flexible time and location and cost savings. "Hoping to improve my professional level" is the main purpose to participate in CME in both 2018 and 2023 surveys [124 (75.61%) vs. 127 (77.44%)]. "Professional skills and techniques" and "New advances in the specialty" are the contents of most interest. Conclusions:Obstetricians and gynecologists should raise the awareness to participant in CME. Relevant departments should establish a standardized system and an effective supervision and management mechanism, and take flexible education modes with the use of the Internet. Online education can achieve similar teaching effects and also improve learners' satisfaction.

Various contents, relatively insufficient class hours, few practical operation opportunities and lack of teacher-student interaction are the main difficulties in clinical clerkship teaching of gynecology and obstetrics. In this study, the flipped classroom, surgery simulation training system and online self-test module are added to the clinical clerkship teaching of obstetrics and gynecology, and also the WeChat group interactive platform is established to make up for the deficiency of traditional teaching mode. The questionnaire survey showed that 59 clerkship students' satisfaction with the course was 92.6 points, 98.3% of students thought that the surgery simulation training was helpful, and 93.2% of them thought that the flipped classroom was helpful, and the students' scores of the final exam was higher than those of the previous students in the same period with the same difficulty of the exam. Therefore, rational use of flipped classroom, surgery simulation training system and other modules can improve the overall effect of clinical clerkship teaching in gynecology and obstetrics to a certain extent.

Objective To explore the value of primary and Advanced levels of laparoscopic simulating training in different seniority of gynecologic residents.Methods 77 residents in their first to forth training-year were divided into two groups:1-2 year resident and 3-4 year resident,trained with different levels of simulating training plans respectively and then assessed in the Department of Obstetrics and Gynecology in Peking University Third Hospital.Results The qualified rate of primary and advanced simulation training was 85.7％ and 57.1％ respectively.The qualified rate of primary training (80.4％ vs.100.0％,P=0.028) and advanced training (12.5％ vs.57.14％,P=0.000) were significantly different between 1-2 year residents and 3-4 year residents.The operative skills improved significantly in all the residents.In the 1-2 year residents,the scores of the primary training increased more obviously,while in the 3-4 year residents,the scores of the advanced training increased significantly.Conclusion It might be more effective for residents with different seniority to receive different levels of simulating training accordingly,so as to improve their laparoscopic operative skills more effectively.

Objective To summarize the surgical experience in robotic-assisted laparoscopic partial nephrectomy,and to investigate the efficacy and safety of this surgery.Methods The clinical data of 12 patients who underwent robot-assisted laparoscopic partial nephrectomy in Changhai Hospital from March to July in 2012 were analyzed.All the patients were male and the age range was 43-66 years.In 4 cases the tumors were in the left kidney,and 8 in the right.In 7 cases the tumors were in the dorsal part of the kidney,and 2 in the ventral part.There were 3,5 and 4 cases in the upper,middle and lower pole of the kidney respectively.Preoperative GFR test was normal in all cases.Kidney CT scan showed the maximum diameters of the tumors were 2.0-5.8 cm,with an average of 3.3 cm.The pre-operative stages in all cases were T1N0M0.Results The surgery was successfully completed in all cases.The mean duration of the surgery was 160-310 min,with an average of 242 min.The blood loss was 30-300 ml,with an average of 135 ml,and the intraoperative blood transfusion was unnecessary.The warm ischemia time was 20-49 min,with an average of 31 min.There was no intraoperative morbidity,and no conversion to open surgery.The postoperative length of hospitalization was 9-31 d,with an average of 14 d.Gross hematuria arose in 1 patient at 1 week after the surgery.The post-operative pathology showed renal clear cell carcinoma with Furhman Grade Ⅱ in 11 cases,and renal angiomyolipoma in 1 case.The maximum diameters of the tumors were 2.0-5.0 cm,with an average of 3.5 cm.The tumor resection margin was negative in all cases.Conclusions Robot-assisted laparoscopic partial nephrectomy is safe and effective for local renal tumors.This surgery has significant advantage over traditional laparoscopic partial nephrectomy,in terms of the resection of the renal tumors and the reconstruction of the kidney.

Objective:To summarize the construction and practice of the compulsory postgraduate course "reproductive genetics in gynecology and obstetrics" in Department of Gynecology and Obstetrics, Peking University, and to evaluate the teaching effect of this course.Methods:A total of 139 postgraduates who studied in Department of Obstetrics and Gynecology, Peking University, from 2019 to 2021 were enrolled as subjects, and a syllabus was constructed through a top-level design based on the "biological-psychological-social medicine pattern", with the teaching objectives of reproductive genetics theory, clinical translation, genetic counseling methods, and research advances. The teaching effect was evaluated by analyzing teaching assessment results, teaching evaluation feedback, and teaching achievements. SPSS 26.0 software was used to perform the t-test and the chi-square test. Results:The written test score, usual performance score, and total score of the postgraduate students in 2021 were higher than those in 2019 and 2020 [(73.50±8.19) vs. (70.94±14.90); (68.60±2.82) vs. (68.22±4.58); (90.58±4.18) vs. (89.49±7.60)], with significant differences in written test score and total score ( P<0.05). There was a high degree of satisfaction with the feedback of teaching, and 85.61% (119/139) of the students selected "great satisfaction"; in particular, there were increases in the degree of satisfaction with expanding research ideas and reflecting the advances in this discipline, but with no significant difference. There was a significant increase in the number of published articles. Conclusion:For the active implementation of the course of "Reproductive Genetics in Obstetrics and Gynecology", improving the teaching process in a planned and step-by-step way through a top-level design in advance can help to expand research ideas for future research work among postgraduates in obstetrics and gynecology and promote the sustainable development and improvement of the teaching of the emerging interdisciplinary discipline of reproductive genetics in obstetrics and gynecology.
