ABSTRACT
Objective:To explore the application and teaching effect of TSPV (short for theoretical teaching, simulated surgical skills training, practical surgery training, and video-based review) 4-step teaching in skill training of gynecologic laparoscopic surgery.Methods:A total of 30 trainees who participated in gynecologic laparoscopic surgery training were randomly divided into two groups, with 15 in each group. The experimental group received TSPV 4-step teaching, while the control group adopted traditional teaching and completed training and assessment in stages. The general data, training assessment results, teaching feedback and satisfaction survey of the two groups were compared and analyzed. SPSS 20.0 was used for t-test and Chi-square test. Results:There was no statistical difference in age, gender distribution, education background, clinical working experiences and other general data between the two groups. There was no significant difference in the theoretical examination scores between the two groups [(85.3±4.6) vs. (83.4±4.3), P=0.252]. The scores of simulated operation assessment [(91.7±5.2) vs. [(72.4±5.9), P<0.001] and clinical practice assessment [(88.5±4.8) vs. (82.7±6.7), P=0.011] in the experimental group were better that those in the control group. In addition, the experimental group had a better overall evaluation of teaching satisfaction. Conclusion:TSPV 4-step teaching is a more optimized and popular gynecologic laparoscopic training mode, which is recommended to further promote the validation in teaching.
ABSTRACT
Academic medical postgraduate recruitment and training is facing a new dilemma due to the overall implementation of resident standardization training and the combination of postgraduate education in professional master degree of clinical medicine and resident standardization training.We optimize and marry together journal club and lab meeting education methods in academic medical postgraduate training of obstetrics and gynecology on the basis of its teaching characteristics, and develop a new form of academic graduate student training of obstetrics and gynecology.This new method is expected to effectively improve the academic postgraduates' research interests, research capacity and the teaching quality of obstetrics and gynecology for academic postgraduates.
ABSTRACT
Objective To investigate the contribution of hypoxia-inducible factor inhibitor YC-1 to cisplatin chemo-sensitivity to human ovarian cancer cells A2780s in vitro. Methods Ovarian cancer cells were divided into four groups which were treated with saline, YC-1, cisplatin, and YC-1+cisplatin, separately, mRNA of HIF-1αand VEGF in the A2780s cells were detected by real-time fluorescence quantitative PCR by calculating 2-△△CT;the protein were detected by Western blot, to evaluate the change of hypoxia and angiogenesis capabilities under the ovarian cancer microenvironment. Results Compared with the control group, mRNA and protein of HIF-1αand VEGF expressed less in the group of YC-1, cisplatin and YC-1+cisplatin;while, those in the group of YC-1+cisplatin were lower than the monotherapy (P<0. 05), but no significant difference was detected between the YC-1 and cisplatin groups, and the expression of HIF-1αand VEGF mRNA were positively related(r=0. 830 5)in each group. Conclusion YC-1 exerts the antitumor effect and may contribute to sensitivity to cisplatin in the therapy of ovarian cancer.
ABSTRACT
INTRODUCTION: This study is a meta-analysis of the efficacy and safety of the application of adjuvant material in the repair of anterior vaginal wall prolapse and a sub-category analysis of the use of nonabsorbable synthetic mesh, biological graft and absorbable synthetic mesh. METHOD: Pubmed, Embase and Ovid databases were searched for published randomized controlled trials from 1980 to February 2012 on the treatment of anterior vaginal wall prolapse with adjuvant materials. A comprehensive meta-analysis applying Revman5.1 analysis software was performed. RESULTS: A total of 20 randomized controlled trials including 2,313 participants were recognized. The result showed that repair with adjuvant materials was better and more effective; nevertheless, use of adjuvant materials resulted in longer duration of surgery and more peri-operative bleeding when compared with the control group, but no significant differences were observed between the two groups regarding visceral injury, postoperative pain, urinary tract infection rate, new stress incontinence and new dyspareunia. CONCLUSION: Adjuvant material is worthy of clinical popularization, especially the biological graft type because of its lower anatomy failure rate and no difference in safety compared with the control group. However, exposure to adjuvant materials and erosion rate are high, which are the most important aspects to be improved.

Objective To search the literature of randomized controlled trials on the treatment of anterior vaginal wall prolapse with adjuvant materials and compare the efficacy and safety of anterior vaginal wall prolapse repair with and without adjuvant materials.Methods Searches were made in the databases of Pubmed,Embase and Ovid for randomized controlled trials from 1980 to 2012 on the treatment of anterior vaginal wall prolapse with adjuvant materials.Comprehensive meta-analyses were conducted with Revman 5.1 analysis software to compare vaginal wall anatomy failure rate,operative duration,intraoperative bleeding volume,postoperative visceral injury,pelvic pain,urinary infection,material exposure,material erosion,de novo urinary incontinence and de novo dyspareunia in the adjuvant materials repair and repair without adjuvant materials groups.Results A total of 20 randomized controlled trials including 2313 participants were retrieved.The shortest average follow-up period was 3 months and the longest 36 months.Compared with repair without adjuvant materials,the application of adjuvant materials in anterior vaginal wall repair reduced vaginal front wall prolapse anatomy failure rate lower anatomy failure rate,had a longer operating duration,more peri-operative bleeding and lower urinary tract infection rate.The comprehensive effects were as follows:P＜0.01,RR =0.51,95％CI:0.41-0.64;P ＜0.01,weighted mean differenece (WMD) =16.25,95％ CI:8.07-24.43;P =0.01,WMD =35.00,95％ CI:6.90-63.11 ;P =0.03,RR =0.51,95％ CI:0.28-0.93,respectively,but the comparison of two groups around in visceral injury,postoperative pain,de novo stress urinary incontinence and de novo dyspareunia had no significant differences (P =0.07,0.58,0.54 and 0.67) and the average materiale exposure and rosion rate were 4.37％ (27/618) and 7.69％ (24/312) respectively.Conclusions The application of adjuvant materials in anterior vaginal wall repair can improve the postoperative recurrence.But no obvious differences exist in the incidence of complications in anterior repair with adjuvant materials and repair without adjuvant materials.
ABSTRACT
This study investigated the anti-HSV-2 effect of alumen through in vitro and in vivo experiments. Viable cell counting was employed to assess the toxicity of alumen on Vero cells. The inhibition rate of HSV-2 was defined as the cytopathic effect (CPE) of the cells infected with the virus. Alumen suppositories of different concentrations were vaginally applied to the guinea pigs which were then infected with HSV-2 via a vaginal route. The clinical symptoms were observed and the local virus titer calculated. The results showed that alumen had an in vitro anti-HSV-2 effect by means of antiviral duplication, direct killing of the virus, and antiviral adsorption. Alumen suppositories of different concentrations could reduce or completely inhibit HSV-2 infection in guinea pigs. It was concluded that alumen had an in vitro anti-HSV-2 effect through multiple approaches and it could suppress in vivo vaginal HSV-2 infection of guinea pig to some extent.
