ObjectiveTo investigate the effect of finasteride on hemorrhage in peri-operation of transurethral plasmakinetic enucleation of prostate (TUPKEP).Methods150 patients with benign prostatic hyperplasia (BPH) were randomly divided into 3 groups:control group without finasteride (n= 50),treatment groupl 1 with finasteride 5 mg daily for 7 days(n= 50) and treatment group 2 with finasteride 10 mg daily for 7 days(n= 50) before and after operation.All patients received TUPKEP and the data were recorded,including total blood loss,operation time,amount of washing fluid during operation,blood loss of per gram tissue,blood loss per minute,washing time after operation,amount of washing fluid after operation,and rebleeding rate within 3 months after operation.ResultsThe 150 patients successfully received TUPKEP.The total blood loss,amount of washing fluid during operation,operation time,blood loss per gram tissue,amount of washing fluid after operation,washing time after operation and rebleeding rate within 3 months after operation in treatment group 1 and 2 significantly reduced as compared with control group (P＜0.05).The blood loss per minute were (1.77±0.89) ml/min,(1.71±0.82) ml/min and (1.70±0.81) ml/min in 3 groups,respectively,and there were no significant differences among groups (P＞ 0.05).There were no significant differences between treatment group 1 and 2 in the total blood loss,operation time,amount of washing fluid during operation,blood loss of per gram tissue,blood loss per minute,washing time and amount of washing fluid after operation (P＞0.05).The rebleeding rate within 3 months after operation in treatment group 1 (8/35) and treatment group 2 (3/26) decreased as compared with control group (17/39) (x2= 3.544 and 7.523,P=0.016 and 0.025)and it was lower in treatment group 2 than in treatment group 1 (x2 = 1.293,P = 0.044).Conclusions The application of finasteride in peri-operation of TUPKEP can reduce hemorrhage.

Objective To investigate the role of miR-155 in diabetic nephropathy(DN)and its mecha-nism. Methods MiR-155 expression level in kidney was detected by real-time PCR and in situ hybridization. The target gene of miR-155 was predicted by bioinformatics and verified by Western Blot and double luciferase reporter activity. Western Blot was used to detect the related marker proteins of mesangial cells proliferation and mesangial matrix. Results (1)The expression of miR-155 increased in DN renal tissue and high glucose-stimulated renal cells.(2)MiR-155 was related to the regulation of Smad5 gene expression.(3)MiR-155 promoted the mesangial cells proliferation and increased extracellular matrix by down-regulating Smad5 expression. Conclusions MiR-155 can promote the mesangial cells proliferation and renal fibrosis by regulating Smad5 gene,providing a basis for further understanding the pathogenesis of DN.
