Objective To analyze the different approaches and their indications in the laparo-scopic treatment of upper urinary tract transitional cell carcinoma. Methods 94 patients with upper urinary tract transitional cell carcinoma were divided to two groups. Group A (63 cases) with renal pelvic and ugper ureteral carcinoma were treated with retroperitoneal approach laparoscopic surgery and transurethral reseetoscope surgery. Group B (31 cases) with middle ureteral carcinoma including 6 cases with ureteral local infiltration were treated through 70° recumbent position transperitoneal ap-proach laparoscopic surgery combined with bladder cuff resection. The operative time, blood loss, the intestinal functional recovery time and post-operative complications were recorded. Results All 94 procedures were successfully completed, with no complication during the surgery. The mean operation time of A and B group was 156.5 and 160.8 min;the mean blood loss was 80 and 86 ml; the mean hos-pital stay was 8 and 8. 5 d; the time of bowel functional recovery of group A and group B was 24-48 and 24-72 h, respectively. 84 cases were followed-up with mean follow-up time of 23 months. Three eases and 5 cases were found having bladder tumor in the group A and group B. The incision and port metastasis was not found. Conclusions It is safe and feasible to treat the upper urinary tract transi-tional cell carcinoma laparoscopically. The selection of operating approach is mainly based on the loca-tion and local infiltration status of the tumor.

This article reviews the training model of orthopedic residents in the world's top orthopedic hospitals, such as Hospital for Special Surgery Affiliated to Cornell University and The Affiliated Hospital of Harvard University Medical School, and it is found that there are differences between China and the US in the training of orthopedic residents in the aspects of the admittance system of physicians, the setting of training contents , and the training model of orthopedic residents . The training of orthopedic residents in the US adheres to the concept of elite education and pays attention to the construction of tutors and learning atmosphere. The enlightenment to the training of orthopedic residents in China includes further clarification of the training objectives of orthopedic residents , improvement of the stage-based training system , integration of excellent medical teaching resources , and improvement of teaching methods and assessment systems.

Objective To evaluate the efficacy and safety of basiliximab (BAS) and antithymocyte globulin (ATG) in immune induction therapy in kidney transplantation by systematic review and Meta-analysis. Methods Prospective randomized controlled clinical trials screening and comparing BAS and ATG in immune induction therapy in kidney transplantation were systematically searched from global databases, screened and compared. The quality of clinical trials was evaluated by Jadad scoring system and data extraction was performed. The effects of BAS and ATG on the incidence of acute rejection, survival rate of kidney allografts, survival rate of recipients, incidence of delayed graft function, infection, cytomegalovirus infection, malignant tumor, leukopenia and thrombocytopenia at 1 year after kidney transplantation were analyzed. Results A total of 10 clinical trials in English consisting of 1 721 kidney transplant recipients were searched, including 883 cases in the ATG group and 838 cases in the BAS group. No significant differences were observed in the incidence of acute rejection, survival rate of kidney allografts, survival rate of recipients, incidence of delayed graft function, infection, cytomegalovirus infection and thrombocytopenia at postoperative 1 year between the ATG and BAS groups (all
