ABSTRACT
Objective@#Refine and understand the characteristics of different types of bystanders, in order to maximize the exploitation and utilization of bystanders as potential resources for anti bullying, so as to provide more targeted guidance for the formulation of intervention programs.@*Methods@#In this study, 1 279 students from two middle schools in Beijing and Anhui Province and two high schools in Guangdong Province and Guangxi Zhuang Autonomous Region were administered with Participation Role Questionnaire (PRQ) and Peer Nomination Questionnaire.@*Results@#There was a significant difference between male and female in the role of onlooker( χ 2=96.92, P <0.01). Female students were more likely to play the role of defender and outsider, while male students were more likely to play the role of reinforcer( χ 2=31.87, P =0.01). And there were significant differences in the distribution of bystander roles in different grades. The chi square test results were( χ 2=456.26, P <0.01).@*Conclusion@#The bystander plays an important role in the occurrence of bullying incidents. It is an important direction of school bullying intervention programs to promote the positive transformation from passive bystander to active bystander.
ABSTRACT
Objective To introduce the technique and report our initial experience of transvesical robot assisted radical prostatectomy (TvRARP).Methods From April 2018 to August 2018,10 patients underwent TvRARP performed by a single surgical team were retrospectively reviewed.Preoperative data of patients [aged (58.6 ± 9.4) years,BMI (26.5 ± 3.1) kg/m2,tPSA (19.5 ± 4.1) ng/ml,biopsy Gleason score 6(6-7),prostate volume (33.4 ± 15.8) ml and IIEF-5 score 12 (10-16)] were collected.Preoperative study revealed 8 cases of cT1c,1 case of cT2a and 1 case of cT2b.All patients were continent preoperatively.During the surgical procedure,the bladder was opened,and a circumferential incision was then made around the internal urethral orifice.Initially,posterior dissection of bilateral vas deferens and seminal vesicles was performed,followed by posterior dissection towards apex.Lateral dissection of neurovascular bundles was performed before anterior dissection towards apex.The exposed urethra was transected and specimen was removed.Vesicourethral anastomosis and closure of bladder was performed in a standard way.Results All 10 cases were successfully performed robotically without conversion,transfusion or other major intraoperative or postoperative complications.Postoperative pathology confirmed 6 cases of pT2a,3 cases of pT2b and 1 case of pT2c [median Gleason score 6 (6-7)].One case was reported positive surgical margin.Operative time was (140.5 ± 35.5) mins.Estimated blood loss was (65.5 ± 35.5) ml.Urethral catheter was removed at 7 days postoperatively.Nine patients achieved urinary continence (0 pads) immediately after the removal of urinary catheter,while 1 patient returned to full continence at 2 weeks postoperatively.During a mean follow-up of 3 months (2-4 months),no biochemical recurrence was detected (tPSA ＜ 0.2 ng/ml).At 2 months postoperatively,IIEF-5 score was 11 (8-13) and no statistically difference was made compared with preoperative data (p ＞ 0.05).Conclusions Transvesical approach is a valid alternative of RARP in patients bearing localized low-risk prostate cancer.Tumor control and preservation of erectile function remains to be determined by long term follow-up.
ABSTRACT
Objective To introduce the technique and report our initial experience of Retziussparing robotic-assisted laparoscopic radical prostatectomy (RALP) and compare perioperative outcomes with the standard veil of Aphrodite technique (Veil technique).Methods nineteen Retzius-sparing RALP and 20 Veil nerve sparing RALP with posterior reconstruction for T1c to T2c prostate cancer performed by a single surgical team between 2015 January and 2016 December were retrospectively reviewed.Preoperative data of patients in Retzius-sparing group [patient age (66.3 ± 5.9) years,BMI (25.5 ± 3.1) kg/m2,tPSA (16.4 ± 5.0) ng/ml,biopsy Gleason score 6 (5-7),prostate volume (32.7 ± 7.4) ml and IIEF-5 score 14(5-18)] and Veil group[patient age (64.6 ±7.3) years,BMI (25.5 ±2.0) kg/m2,tPSA (18.5 ± 11.0) ng/ml,biopsy Gleason score 7(5-8),prostate volume (31.4± 10.8)ml and IIEF-5 score 15(6-19)].No significant difference was found between the two group in the above parameters (all P ＞ 0.05).All patients were continent preoperatively.Retzius-sparing RALP and Veil nerve sparing RALP were performed via transperitoneal RALP.Operative time,estimated blood loss,postoperative hospital stay,postoperative staging,postoperative Gleason score,return of urinary continence and postoperative IIEF-5 score of the two groups were statistically analyzed.Results All 39 cases were successfully performed robotically without conversion,transfusion or other major intraoperative and postoperative complications.Postoperative pathology confirmed pT2a 5 cases,pT2b 8 cases and pT2c 6 cases in Retzius-sparing group and pT2a 7 cases,pT2b 5 cases and pT2c 8 cases in Veil group (all P ＞ 0.05).For Retzius group,operative time was (106.5 ± 26.4) min and estimated blood loss was (48.9 ± 20.2) ml;for Veil group,operative time was (93.2± 20.8) min and estimated blood loss was (42.5 ± 16.8) ml.No significant difference was found in the above parameters (all P ＞ 0.05).Urethral catheter was removed at postoperative 7-day (Retzius-sparing group) and 21-day (Veil group),respectively.18 patients in Retzius-sparing group achieved urinary continence (0 pads) immediately after the removal of urinary catheter,while 1 patient returned to full continence in 2 weeks postoperatively.Patients in Veil group returned to continence (6.8 ± 3.6) weeks postoperatively (P ＜ 0.001).At 3-month follow up,IIEF-5 score was 14 (4-16) in Retziussparing group and 14 (4-18) in Veil group;no significant changes was noted in preoperative and postoperative IIEF-5 score in both groups,or in postoperative IIEF-5 scores in the two groups (P ＞ 0.05).No sign of tumor recurrence was appreciated for all cases (tPSA ＜ 0.2 ng/ml) during follow-up of 6 months (3 to 12 months).Conclusions Retzius-sparing RALP and the Veil nerve sparing RALP were both effective for the surgical treatment of localized prostate cancer.Our data revealed no statistical difference in perioperative outcomes between the two approaches,however,the Retzius-sparing technique seemed to yield a better outcome regarding early return to urinary continence postoperatively.
