摘要

目的探讨芪卫颗粒延缓糖尿病肾病（DN）肾间质纤维化的分子作用机制。方法自发性2型糖尿病KK-Ay小鼠45只

采用高脂饲料喂养制备DN模型。将造模成功小鼠随机分为模型组、中药组[芪卫颗粒20g/（kg·d）灌胃]、西药组[缬沙坦胶囊10mg/（kg·d）灌胃]

每组15只

另设C57BL/6J小鼠15只作为正常组

连续给药12周。采用免疫组织化学法检测各组小鼠肾组织中转化生长因子β1（TGF-β1）表达

免疫印迹法检测磷酸化Smad2（P-Smad2）、磷酸化Smad3（P-Smad3）、Smad7及整合素连接激酶（ILK）的表达

实时荧光定量PCR法检测ILKmRNA表达。结果模型组小鼠肾组织中TGF-β1、P-Smad2、P-Smad3、ILK及ILKmRNA表达较正常组明显增加（P<0.01）

Smad7表达明显下降（P<0.01）。中药组及西药组TGF-β1、P-Smad2、P-Smad3、ILK及ILKmRNA表达较模型组显著减少（P<0.05或P<0.01）

Smad7表达明显增加（P<0.01）。中药组P-Smad3表达较西药组增加（P<0.05）

其余指标两组比较差异无统计学意义（P>0.05）。结论芪卫颗粒通过下调TGF-β1、P-Smad2、P-Smad3、ILK的表达

上调Smad7的表达

影响TGF-β1/Smads信号通路

从而延缓了DN肾脏纤维化的发生发展。

Abstract

Objective To research the molecular mechanism of Qiwei Granules [granules of Huangqi （Radix Astragali） and Weimao （Euonymi Ramulus）] to treat interstitial fibrosis in diabetic nephropathy （DN）. Methods KK-Ay mice with spontaneous type 2 diabetes were fed with high-fat fodder to establish DN models. Forty-five successful model mice were randomized into model group

Chinese medicine group and western medicine group

with 15 in each. The Chinese medicine group was gavaged with 20 g/（kg·d） crude drug of Qiwei Granules and the western medicine group was gavaged with 10 mg/（kg·d） valsartan capsules. Fifteen male C57BL/6J mice were chosen as the normal group. The administration lasted for 12 weeks. The expressions of transforming growth factor-β1 （TGF-β1）

phosphorylated-Smad2 （P-Smad2）

P-Smad3

Smad7

integrin-linked kinase （ILK） and ILK mRNA were examined with immunohistochemistry

Western blot and quantitative real-time polymerase chain reaction respectively. Results Comparing with the normal group

the expressions of TGF-β1

P-Smad2

P-Smad3

ILK and ILK mRNA in the model group were significantly increased （P<0.01）

but the expression of Smad7 was significantly decreased （P<0.01）. Comparing with the model group

the expressions of TGF-β1

P-Smad2

P-Smad3

ILK and ILK mRNA in both administration groups were significantly decreased （P<0.05 or P<0.01）

but the expression of Smad7 was significantly increased （P<0.01）. Comparing with the western medicine group

the expression of P-Smad3 was significantly increased in the Chinese medicine group （P<0.05）. Conclusion Qiwei Granules can block TGF-β1/Smads signaling pathway and delay the progression of renal interstitial fibrosis by down-regulating the expressions of TGF-β1

P-Smad2

P-Smad3 and ILK and up-regulating the expression of Smad7.
