Objective To explore whether therapeutic dosing timing of proteasome inhibitor bortezomib(BZ) would impact its clinical efficacy .Methods From 2012 to 2018 ,35 biopsy-confirmed cases of acute antibody-mediated kidney transplant rejection (AMR) were collected .They received intravenous immunoglobulin (IVIG) plus sirolimus (Sir) plus bortezomib (BZ) .Three groups were assigned according to dosing timing of BZ .After a diagnosis of AMR ,ET (early treatment ) group began BZ dosing within 7 days (n=16) while DT (delayed treatment) group within 8-14 days (n=11) and LT (late treatment) group > 14 days (n= 8).Their clinical parameters and incidence of complications were analyzed .Results DSA reversal rate of ET ,DT and LT groups was 87 .5% , 45 .5% and 25 .0% (P=0 .006) while DSA declining rate 93 .8% ,90 .9% and 50% respectively (P=0 .019);recurrent rate of AMR was lower in ET/DT group than LT group (6 .6% vs 10% vs 75% , P=0 .042) .No significant differences existed in blood perfusion score of allograft at 1 month post-dosing among three groups .In three groups ,creatinine (Cr) of ET group was lower than DT group at month 1/3/12 while DT group was lower than LT group .No significant difference existed in the incidence of adverse reactions among 3 groups .Conclusions More likely to enter the window period , early dosing of BZ is more effective for treating acute AMR .An earlier intervention yields a better efficacy .

Objective To compare the impact of bowel preparation on postoperative complications of patients undergoing radical cystectomy(RC) with ileal conduit diversion(ICD) by meta-analysis.Methods All literature were collected from VIP,CNKI,WanFang Data,CBMdisc,Pubmed,Medline,Embase dated from inception to April 2016.Then literature were grouped into mechanical bowel preparation and nonmechanical bowel preparation,whose differences in the wound,intestinal function,infection and other complications were compared.Results Three RCTs,four cohort studies and 656 cases were taken into account.No statistical difference was observed in the wound infection,wound dehiscence,fascia dehiscence,intestinal obstruction,anastomosis fistula,intestinal fistula,urinary leakage,death of indicators between the two groups.Conclusion Preoperative mechanical bowel preparation did not reduce the occurrence of postoperative complications of the patients with RC undergoing ICD.

Objective To explore the feasibility of making cystoscope training model with rapid prototyping technology and its training method in cystoscope operation. Methods Constructed a cystoscope training model, and designed a set of corresponding training methods ac-cording to the process and behavioral essentials of cystoscope operation. Selected 20 students who have never learned cystoscope operation and trained them with the new designed cystoscope training mode and training methods, and the training results were verified. Results Compared before and after the training, the operation time of all the trainees were significantly shortened, and their operation steps and skills were more proficient. Conclusion Cystoscope training model can help beginners to grasp the theoretical basis of cystoscopy, operation steps, and behavioral essentials, so as to shorten the learning curve of the cystoscope operation.

This article describes a novel Multifunctional and Transparent Urinary System Model (MTUSM), which can be applied to anatomy teaching, operational training of clinical skills as well as simulated experiments in vitro. This model covers kidneys, ureters, bladder, prostate, male and female urethra, bracket and pedestal, etc. Based on human anatomy structure and parameters, MTUSM consists of two transparent layers i. e. transparent organic glass external layer, which constraints the internal layer and maintains shape of the model, and transparent silica gel internal layer, which possesses perfect elasticity and deformability. It is obvious that this model is preferable in simulating the structure of human urinary system by applying hierarchical fabrication. Meanwhile, the transparent design, which makes the inner structure, internal operations and experiments visual, facilitates teaching instruction and understanding. With the advantages of simple making, high-findelity, unique structure and multiple functions, this model will have a broad application prospect and great practical value.
