OBJECTIVE To observe the effect of Qi Kwai Granule particles on the expression of in.terleukin 6(IL-6),monocyte chemotactic protein 1(MCP-1) and transforming growth factor-β1(TGF-β1)in diabetic nephropathy(DN) rats ...OBJECTIVE To observe the effect of Qi Kwai Granule particles on the expression of in.terleukin 6(IL-6),monocyte chemotactic protein 1(MCP-1) and transforming growth factor-β1(TGF-β1)in diabetic nephropathy(DN) rats and evaluate the protective effect of Qi Kwai Granule particles against renal injury of diabetic nephropathy.METHODS This experiment adopts adopted the high-sugar-highfat diet and intraperitoneal injection of 2% STZ+ unilateral renal ligation to establish rat model of diabet.ic nephropathy.50 model rats were then randomly divided into model group,Irbesartan group,Qi Kwai Granule particles of high,medium,low dose group,10 rats in each group.10 normal rats were set as the sham operation group.Intragastric administration for 8 weeks were measured in rats.Measure the value of rat blood glucose by blood glucose meter,the determination of serum interleukin 6(IL-6) con.tent by ELISA,the expression of MCP-1 and TGF-β1 by immunohistochemistry method.The value of rat blood glucose were measured by blood glucose meter.Serum interleukin 6(IL-6) were determinat.ed by ELISA.Expression of MCP-1 and TGF-β1 were evaluated by immunohistochemistry method.RE.SULTS The blood glucose of Qi Kwai Granule particles of high,medium groups were decreased com.pared with those of the model group(P<0.05).The content of IL-6 of Qi Kwai Granule particles of high,medium groups were reduced(P<0.01).The content of MCP-1,TGF-β1 in kidney of Qi Kwai Granule particles of high,medium,low dose groups were decreased(P<0.01).CONCLUSION Qi Kwai parti.cles have protective effect on renal tissue of diabetic nephropathy rats.Its mechanism might be related to the decrease of blood glucose value and IL-6,the inhibition of the expression of MCP-1 and TGF-β1.展开更多
