摘要:

目的观察尿毒清对阿霉素(ADR)肾病大鼠肾脏转化生长因子β1(TGFβ1)、金属蛋白酶1组织抑制剂(TIMP1)、纤溶酶原激活物抑制物1 (PAI1)和骨调素(OPN)mRNA 表达的影响,探讨尿毒清治疗慢性肾脏疾病的机制。方法成年雄性SD大鼠24只,采用单侧肾切除加重复尾静脉注射ADR的方法制作ADR肾病模型,随机分为正常组(N组)、模型组(M组)、尿毒清组(Ni组)、贝那普利组(B组)4组,每组6只。用药第4、8周后观察各组大鼠24?h尿蛋白定量、血脂、血浆总蛋白(TP)、血浆白蛋白(ALB)、尿素氮(BUN)、肌酐(Scr)的水平,实时荧光定量PCR测定第8周肾组织中TGFβ1、TIMP1、PAI1及OPN mRNA的表达。结果尿毒清和贝那普利均能减少ADR肾病大鼠尿蛋白,降低BUN、Scr,升高血浆蛋白,纠正脂代谢紊乱,减少TGFβ1、TIMP1、PAI1及OPN mRNA的表达,与M组相比有显著差异(P<0.01);而Ni组PAI1 mRNA水平较B组显著降低(P<0.01)。结论尿毒清可下调ADR肾病大鼠肾脏组织TGFβ1、TIMP1 、PAI1及OPN mRNA的合成,可能是其治疗慢性肾脏疾病的重要机制之一。

Abstract:

To explore the mechanisms of the beneficial effects of Niaoduqing, and to investigate the effects of Niaoduqing on expressions of renal transforming growth factorbetal, and tissue inhibition of metalloproteinase1, plasminogen activator inhibitor1 and osteopontin mRNAs in rats with Adriamycininduced nephropathy. MethodsThe male rats were randomly divided into four groups: the normal group(N group), the model group(M group), the Niaoduqing group(Ni group)and the Benazepril group(B group). 24hour urinary protein excretion  and renal function were determined at 4 and 8 weeks. Expressions of transforming growth factorbetal(TGFβ1), tissue inhibition of metalloproteinase1( TIMP1), plasminogen activetor inhibitor1(PAI1) and osteopontin (OPN) mRNA were determined by realtime quantitative RTPCR. ResultsNiaoduqing and Benazepril effectively reduced the levels of 24hour  urinary protein excretion, Bun, and Scr, elevated protein levels, corrected fat metabolic disorder, and downregulated expressions of TGFβ1, TIMP1, PAI1 and OPN mRNAs(P<0.01)compared with the M group. Niaoduqing could significantly inhibit expression of PAI1 mRNA compared with that of Benazepril(P<0.01). ConclusionNiaoduqing can downregulate expressions of TGFβ1, TIMP1, PAI1 and OPN mRNAs in renal tissues of rats with Adriamycininduced nephropathy, which may be its active mechanism in treating chronic renal diseases.
