RESUMEN
AIM:To investigate the antagonism mechanism of benazepril on renal fibrosis of unilateral uretreal obstructire (UUO).METHODS:Fiftyfour Sprague-Dawley (SD) rats were randomly divided into three groups:sham operation group,model group,benazepril group.All the other groups were treated with surgery method of unilateral ureteral ligation to establish a rat model of renal fibrosis except the sham operation group.The pathological changes were observed by Masson staining;the positive staining expression of TGF-β1,Col-Ⅳ,Wnt1,Wnt4 in frozen sections were observed by immunofluorescence staining;the expressions TGF-β1,Col-Ⅳ,Wnt1 and Wnt4 mRNA in renal tissues were detected by real time fluorescence quantitative PCR.RESULTS:Masson staining results:compared with the sham group,the parts of blue dye collagen fiber and the degree of renal fibrosis increased significantly in all modeled groups;compared with the model group,the parts of blue dye collagen fiber and the degree of renal fibrosis decreased significantly in benazepril group.Immunofluorescence and PCR results:compared with the model group,the positive expression of Wnt1,Wnt4,TGF-β1,Col-Ⅳ and mRNA in the benazepril group decreased significantly.CONCLUSION:Benazepril can improve renal fibrosis by inhibiting the expression of TGF-β1,Col-Ⅴ,Wnt1,Wnt4 and ameliorating the level of renal fibrosis.

RESUMEN
AIM: To observe the efficacy of ketosteril in treatm en t of chronic renal failure with high level of plasma Cys-C. METHODS: 60 patients with chronic renal failure were randomly divided into treatmen t group and control group. The control group was adopted a low protein and low p hosphorum diet and correcting symptoms; the treatment group, based on the therap y of the control group, was given ketosteril; 30 healthy subjects were used as t he normal control to observe changes of Cys-C, Scr, TC, HB, and HDL before and after the treatment. RESULTS: The levels of Cys-C and Scr decre ased after the administration of ketosteril (P
RESUMEN
Objective To study the clinical significance of the change of nuclear factor-?_B activity in frequently relapsed nephropathy syndrome.Methods 60 patients with FRNS were involved in the study,30 patients(at relapses)were regarded as test groups A,30 patients(at remission)were regarded as test groups B,30 healthy persons in group C(control group).8W after treatment,after separating neutrophil and distilling nuclear protein,we mensured the activation of nuclear factor -?_B by EMSA.Results Neutrophil nuclear factor -?_B has been activated at relapsed group,but the activity of nuclear factor -?_B in the remission group was lower than the relapsed group P
