Before treatment and 8 weeks after treatment, serum contents of renal function indexes, RAAS molecules and inflammatory factors as well as urine contents of podocyte damage proteins were determined.Results:8 weeks after treatment, serum Scr, BUN, CysC, PRA, AT-II, ALD, IL-1β, IL-6 and TNF-α contents, urine ACR levels as well as podocalyxin, nephrin, CA2AP and podocin contents of both groups of patients were significantly lower than those before treatment, and serum Scr, BUN, CysC, IL-1β, IL-6 and TNF-α contents, urine ACR level as well as podocalyxin, nephrin, CA2AP and podocin contents of LEF group were significantly lower than those of control group, serum PRA, AT-II, ALD contents had no significant difference with control group.Conclusion:Leflunomide combined with losartan potassium therapy can improve the renal function of patients with diabetic nephropathy, and inhibit the inflammatory response injury to glomerular podocyte.展开更多
目的探讨冬虫夏草及雷公藤多甙对糖尿病肾病(DN)大鼠足细胞的保护作用。方法制备DN大鼠模型,将动物随机分为正常对照组(A组)、DN模型组(B组)、冬虫夏草治疗组(C组)及雷公藤多甙治疗组(D组)、两药联合治疗组(E组)。12周后观察24h尿蛋白...目的探讨冬虫夏草及雷公藤多甙对糖尿病肾病(DN)大鼠足细胞的保护作用。方法制备DN大鼠模型,将动物随机分为正常对照组(A组)、DN模型组(B组)、冬虫夏草治疗组(C组)及雷公藤多甙治疗组(D组)、两药联合治疗组(E组)。12周后观察24h尿蛋白排泄量(24hurinary protein count,24hpro)、血糖(Glu)、血尿素氮(BUN)、血肌酐(SCr)、外周血白细胞(WBC)、谷草转氨酶(AST)、谷丙转氨酶(ALT)以及肾重(KW)/体重(BW)等值的变化;HE染色检测肾组织病理变化;透射电镜测量足细胞超微结构变化;免疫荧光方法检测肾皮质nephrin和podocin蛋白表达。结果与A组比较,B组SCr、BUN增高(P<0.05);Glu、KW/BW和24hpro明显增高(P<0.01),肾小球、小管间质及足细胞病变,肾脏皮质nephrin和podocin蛋白表达减少。与B组比较,C、D、E组KW/BW和24hpro降低(P<0.01),肾小球、小管间质及足细胞病变明显减轻;肾脏皮质nephrin和podocin蛋白表达增高。与C组比较,D、E组KW/BW和24hpro降低,肾小球、小管间质及足细胞病变减轻,肾脏皮质nephrin和podocin蛋白表达增高,差异均有统计学意义以E组最为明显(P<0.01)。结论冬虫夏草及雷公藤多甙具有减轻DN蛋白尿,保护及修复DN大鼠足细胞病变的作用。其机制可能与其上调nephrin和podocin蛋白的表达有关。冬虫夏草与雷公藤多甙联合治疗可增加疗效并减轻雷公藤多甙的不良反应。展开更多
