Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P<0.05). The patients with dissected LNs counts of more than 11 for cases with pTl~2 tumor (P<0.05) and more than 16 for cases with pT3 tumor (P<0.05) had better long-term survival outcomes. The post-operative complication rate was 12.1%, which was not significantly correlated with the number of dissected lymph nodes (P>0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.

Objective To compare the treatment efficacy of severe hypospadias between two-stage urethral plate reconstruction procedure and two-stage tubularized transverse preputial island flap procedure. Methods From 2010 December to 2014 December, we retrospectively analyzed 82 cases with severe hypospadias, using two-stage urethral plate reconstruction and two-stage tubularized transverse preputial island flap urethroplasty, respectively.Their mean age in the first operation was 2.4 years, ranged from 2 to 3 years.Hypospadias were penoscrotal type in 32 cases, perineal type in 50 cases.In group A, 42 cases, including penoscrotal type in 15 cases, perineal type in 27 cases, with urethral plate reconstruction procedure underwent two-stage urethroplasty.The transected ventral penile urethral plate and to strip the ventral fibrous tissue were needed in correction of chordee of penis.The patients in group A were underwent the second urethroplasty with urethral plate reconstruction procedure 6-12 months later.In group B, 40 cases,including penoscrotal type in 17 cases, perineal type in 23 cases, who underwent one stage operation in the correction of chordee of penis, only with tubularized preputial island flap forming the part of the urethra.The patients in group B were underwent the second urethroplasty 6 ~12 months later.Results Patients were followed up for 1 to 5 years, mean 3.5 years.No recurrence of penis chordee was noticed.In group A, 6 cases (14.3%) had postoperative fistula.The second fistula repairing was perform 6 to 12 months after the second stage operation.However, still 3 cases were noticed the fistula recurrence, which was cured after the fourth operation.In group B, 3 cases (7.5%) developed fistula, which appeared in the second urethroplasty (P<0.01).They were all treated after the second repairing procedure.In group A, 4 cases were noticed urethral stricture, the urethral stricture rate was 9.5%.The stricture occurred 1 to 3 months after the second operation.After dilation and indwelling catheter, 3 cases resolved the problem. Another case still found the recurrence after 2 months, which the one stage urethral plication and second urethral reconstruction were considered to treat this patient.In group B, 1 cases of urethral stricture, the urethral stricture rate was 2.5%(P<0.01).After dilation and indwelling catheter, this case resolved the problem.In group A, 3 cases had urethral diverticulum, which occurred at a rate of 7.1%, whereas without urethral diverticulum occurred in group B (P<0.01).Those patient with urethral diverticulum accepted the diverticulum removing procedure 3 to 6 months after the second stage procedure.One case was found the urethral fistula, which was treated one year later.The success rate of operation was 69.0%in group A, the success rate of the operation was 90.0%in group B.The difference of the success rate between two groups was statistically significant ( P <0.01 ) . Conclusions With respect to two-stage urethral plate reconstruction procedure in treatment of severe hypospadias, there were the low complication rates of postoperative urinary fistula, urethral stricture and diverticulum in two-stage tubularized transverse preputial island flap procedure.Urethral meatus could be done at the glans of the penis.In addition, the two-stage tubularized transverse preputial island flap procedure provides a good opportunity to practice to master complex hypospadias operation.

objective To evaluate the influence of HLA matching and new immunosuppressants on pre-venting acute rejection of renal allograft in sensitized recipients. Methods 751 recipients underwent renal transplantation were enrolled in this study including 46 sensitized recipients (study group) with PRA be-tween 10%-90% and 705 non-sensitized recipients (control group) with PRA less than 10% pretransplant. All patients in the study group received induction course (ATG 100 mg/d, 5-7 d) plus triple-immunosup-pressive therapy including FK506 + MMF + steroid. The rate of acute rejection and delayed graft function after renal transplantation was analyzed. The influence of HLA matching on preventing acute rejection was al-so evaluated. Results The acute rejection rate in the study group and control group was 30.43% and 19. 57%, respectively, (P < 0.05). The rate of delayed graft function was 60.86% in the study group, signifi-cantly higher than that of the control group (11.87%). There was no statistically difference of one-year pa-tient / graft survival rotes between the two groups. The average serum creatinin levels at one-year posttrans-plantation were similar between the two groups (130 mmol/dl in the study group and 125 mmol/di in the control group). The average loci of HLA matching in the study group (4.2) was significantly higher than that in the control group (2.8). The acute rejection rate in the study group was significantly higher when lo-ci of HLA mismatch ranging from 2-4 compared with loci of HLA mismatch less than 2. The acute rejection rate was significantly higher in the highly sensitized recipients (PRA ranging from 50% -90% pretmnsplant) than that in the less sensitized (PRA ranging from 10% to 20% pretransplant) in the study group. Patients with higher PRA level posttransplantation were prone to developing acute rejection. Conclusion HLA matching and new immunosuppressants can reduce the incidence of acute rejection in sensitized recipi-ents and increase the survival rate of patients and allografts.

Objective To discuss the management of urethral duplication in children. Methods The clinical data of 1 8 children(all are males)with urethral duplication were retrospectivelv ana-lyzed. All the 18 patients were sagittal plane included epispadias in 6,hyposPadias in 4 and Y type in the remaining 8. In 6 cases with epispadias,3 patients underwent excision of the accessorv dorsal ure-thra,3 patients without operation.Urethroplasty was necessary in the patient with a duplicated hypo-spadiac urethra. Of 8 patients with Y-type urethral duplication,7 patients underwent 2 stage repair including displacement of the urethra from the anal canal to the perineum at stage 1 and subsequent urethral reconstruction at stage 2.The ventral urethra which was hypospadias had been excised in the other one. Results All the patients were followed-up. Good cosmetic and functional resuIts were a-chieved in the 3 boys who underwent excision of the accessory dorsal urethra.In the hypospadiac du-plication,2 patients could void spontaneously through a normally positioned granular meatus.One boy presented with urethral stenosis after operated. One boy had a vesicostomy for neuropathic bladder. In Y-type urethral duplications,only 1 patient was successful after 2-stage urethroplasty,3 patients de- veloped urethra stricture or fistula,3 boys need the 2-stage operation,the other 0ne who underwent excision of the ventral urethra could void spontaneously. Conclusions Urethral duplication is a rare congenital anomaly.The clinical presentation varies because of the different anatomical Datterns of this abnormality. Commonly the ventral urethra is most functional and maintained after surgical correc-tion.Surgical management should be individual and depend on the anatomical configuration of the du-plicated urethras.

Objective To investigate the incidence of infection and the effect of anti-infection prophylaxis in renal transplanted patients after Basiliximab induction therapy. Methods A total of 204patients who have received renal transplantation and Basiliximab induction therapy from January 1,2001 to December 31, 2010 in our hospital have been retrospective analysed in this study. These patients were divided into a prophylaxis group (118 cases) with Ganciclovir + Sulfadiazine +Trimethoprim therapy and a control group (86 cases) without any anti-infection prophylaxis.Furthermore, 440 transplanted patients in the same peroid without any induction therapy were also analysed. They were also devided into two groups: an anti-infection prophylaxis group (206 cases)and a control group (234 cases) without any anti-infection prophylaxis. Results In the prophylaxis group with Basiliximab induction therapy, there were 23 patients (19. 5 %, 23/118)experienced hospitalization due to infection, 3 cases (13. 0 %,3/23) among them were severe infection, and 3patients (13.0 %, 3/23) died from vital infection. In the non-prophylaxis control group with Basiliximab induction therapy, 27 patients (31.4 %, 27/86) had infection complication, 7 patients (25.9 % ,7/27) among them were severe infection, and 4 patients(14. 8 % ,4/27)died. The incidence of infection between the above two groups is significantly different (P<0. 05). In the prophylaxis group without induction therapy, the incidence of infection was 15.0 % (31/206), there were no severe infection cases but 7 patients (22. 6 %, 7/31) died from infection. In the non-prophylaxis control group without induction therapy, the incidence of infection was 12. 8 % (30/234), 3 cases among them were severe infection(10. 0 %,3/30)and 5 patients died from infection (16. 7 %, 5/30).The incidence of infection in Basiliximab induced patients without anti-infection prophylaxis is significantly higher than that in patients without induction therapy and anti-infection prophylaxis (31.4 % vs. 12.8 %,P<0.01). Conclusion Basiliximab induction therapy increased the risk of infection, but not the rate of mortality. It is necessary to give anti-infection prophylaxis in renal transplanted patients with Basiliximab induction therapy.
