RESUMO
Objective To assess the relationship between type 2 diabetes and the risk of kidney cancer. Methods PubMed, Medline, CNKI and VIP were used to identify studies which regarded the relationship between type 2 diabetes and risk of kidney cancer up to July 2014. The relative risks (RRs) and the corresponding 95% confidence interals (CIs) were used to estimate the association between type 2 diabetes and the risk of kidney cancer through software STATA. Results 8 studies were included in this analysis. Compared to the popula-tion without type 2 diabetes, there was an increased risk of kidney cancer in the type 2 diabetes patients, the pooled RR (95%CI) was 1. 55 (1. 24,1. 92),P<0. 05. Conclusion Our meta-analysis suggestes that type 2 diabetes can increase the risk of kidney cancer.
RESUMO
Objective To analyze and evaluate the effects of the tissue engineering bladder reconstruction on the upper urinary tract structure and function.Methods The 8 male beagles were randomly divided into the two groups:sham-operation group (group A,n=4)and the collagen scaffold repair group (group B,n=4).The bladder defect animal model was established in the group B by using the collagen scaffold materials to repair the bladder.The renal function related biochemical indicators were detec-ted and the renal Doppler ultrasonic examination was performed in each group before repair and in 23 weeks after repair.The speci-mens from the two groups were performed the gross morphology observation and the histology examination on postoperative 24 weeks.Results The renal Doppler ultrasound examination showed the normal kidney morphology and normal blood flow signal.In the general observation,no calculi and neoplasm were found in the kidney and ureter of the experimental dogs.The renal function related biochemical indicators had no statistically significant differences between the two groups(P>0.05).The histological exami-nation indicated that the organization structure was integrity,the nephrons in each group had no obvious pathological changes.Con-clusion Using the collagen scaffold materials to reconstruct the canine bladder has no adverse influence on the upper urinary tract structure and function,this tissue engineering approach has good feasibility.
RESUMO
To establish a new kind of minimally invasive surgical model of transurethral prostate enucleation operation and method that makes the operation easier and reduces the surgeon learning curve.According to the order and the path of surgical operation,prostate enucleation operation is split into 4 different modules named as A,B,C,D,and it is called modular transurethral enucleation of the prostate.The operation mode optimizes the process of operation design, modularizes the contents of surgical procedures,processes,and reduces the difficulty of the operation,and simplifies the surgical procedure,which can effectively shorten the operation time and make it easy for beginners to carry out and control the procedure.It has a great popularization value.
RESUMO
OBJECTIVE:To investigate the effects of long-term use of calcium channel blocker-Diltiazem(Dil)on the dosage of ciclosporin A and renal function of renal graft recipients.METHODS:Dil was administed in67renal graft recipi?ents,meanwhile who were orally taking CsA with another59renal graft recipients served as controls.The dosages of ci?closporin A of2group were adjusted to the level within therapeutic window,then the dosage of CsA and serum creatinine change of the2groups36mo after drug administration were observed.RESULTS:12mo,24mo and36mo after operation,the synchronized cyclosporin A dosages in Dil group were lower than the control group respectively by14353mg,9656mg and7817mg.No significant differences were found in serum creatinine levels between the2groups within the first12mo after operation.Thereafter,the creatinine levels in the control group has a faster increase and the creatinine level in Dil group was significantly lower than that of the control group18mo～36mo after operation(P
