芪术颗粒对糖尿病肾病气阴两虚、痰浊阻络证大鼠早期蛋白尿抑制作用

Inhibitory Effects of Qi-Zhu Granules on Early Proteinuria in Diabetic Nephropathy Rats with Syndrome of Qi-yin Deficiency and Phlegm Blocking Collaterals

目的:观察芪术颗粒对糖尿病肾病气阴两虚、痰浊阻络证大鼠早期蛋白尿抑制作用。方法:44只大鼠随机分为空白组、模型组、黄葵胶囊组和芪术颗粒组。采用单侧肾结扎合并高热量胆固醇饮食同时复合低剂量链脲佐菌素腹腔注射的方法,建立糖尿病肾病气阴两虚、痰浊阻络证大鼠模型,连续给药8周,观察第4周后大鼠蛋白尿、尿肌酐以及实验结束后血糖、血脂、肝功能和肾脏病理结构的变化。结果:与模型组比较,芪术颗粒可以明显抑制糖尿病肾病早期蛋白尿,促进肌酐排泄,同时调节血脂代谢,保护肝功能,改善肾脏组织病理学变化。结论:芪术颗粒对糖尿病肾病气阴两虚、痰浊阻络证大鼠早期蛋白尿具有独立抑制作用,并不依赖于降血糖作用,体现了中药复方功效与病证的对应关系。

ThisstudywasaimedtoobservetheinhibitoryeffectsofQi-Zhu （QZ）granulesonearlyproteinuria in diabetic nephropathy rats with syndrome of qi-yin deficiency and phlegm blocking collaterals. A total of 44 rats were randomly divided into the blank group, model group, Huang-Kui capsule group, QZ granules group. The rat model of diabetic nephropathy with syndrome of qi-yin deficiency and phlegm blocking collaterals was induced by the combination of unilateral renal artery ligation, diet of high-calorie and high cholesterol, and intraperitoneal injection of low-dose streptozotocin. The medication was given for 8 weeks. The concentrations of protein and creatinine in urine were observed on the 4th week. The blood glucose, blood lipids, liver function and renal pathological changes were observed at the end of the experiment. The results showed that compared with the model group, QZ granules can obvious suppress early proteinuria in diabetic nephropathy, promote creatinine excretion, regulate blood lipid metabolism, protect liver function and improve renal pathological changes. It was concluded that QZ granules had independent inhibition effect on early proteinuria in diabetic nephropathy rats with syndrome of qi-yin deficiency and phlegm blocking collaterals. The effect was independent of lowing blood glucose. It represented the corresponding relation between the syndrome and efficacy in Chinese herb compounds.
