Abstract:
Objective To investigate the effects of artesunate( Art) on renal function and the expression of monocyte chemotactic protein-1(MCP-1)and tumor necrosis factor-α(TNF-α)in rats with type 2 diabetic nephropathy(DN). Methods Thirty six male SD rats were randomly divided into six groups, six rats in each, as the normal control, model control, low-dose Art, middle-dose Art, high-dose Art groups which were intragastrically administrated with Art at the dose of 10, 20 and 30 mg·kg-1 ·d-1 for consecutive 8 weeks, enalapril group, which were intragastrically administrated with enalapril 10 mg·kg-1 ·d-1 for consecutive 8 weeks. Rats were injected with low dosage streptozotocin and fed with high fat and high sugar diets to establish type 2 diabetic nephropathy rat model. After 8 weeks’ treatment, the plasma glucose, 24-hour urine protein, serum creatinine and blood urea nitrogen were measured to evaluate renal function. The pathological morphology of rats was performed. Immunohistochemistry and enzyme linked immunosorbent assay ( ELISA ) were performed to examine the expression levels of MCP-1 and TNF-α,respectively. Results Compared with the model control group, 24-hour urine protein, serum creatinine, blood urea nitrogen and blood glucose were significantly decreased in the treatment groups (P<0. 01). Art significantly decreased the serum expressions of MCP-1 and TNF-α in low-, middle-, high-dose Art group ( 157. 47 ± 38. 53, 138.65±18.03,105.09±12. 64 and 3. 14±0. 38,2. 58±0. 11,2. 25±0. 16) pg·mL-1, compared with model control group (181.71±23.06 and 3. 98±0. 24) pg·mL-1(P<0. 05). Conclusion Art has beneficial effects on type 2 diabetic nephropathy. The mechanism of which may be related to the inhibition of inflammatory factor MCP-1 and TNF-α,further relive the pathological injury of kidney and delay the progress of diabetic nephropathy to some extent.
