Abstract:
Objective: To study the effect of HaikunShenxi on expression of connective tissue growth factor(CTGF) in renal tubules of STZ-induced diabetic nephropathy rats.Methods: SD rats were randomly divided into two groups: normal control and diabetic nephropathy.Diabetes was induced by intraperitoneal injection of STZ.The diabetic models were affirmed upon blood glucose ≥16.5 mmol/L,urinary glucose ≥ ++++ 72h after the injection.And the diabetic rats were randomly divided into four groups: model group,irbesartan treatment group,low and high dose HaikunShenxi treatment group.24-hour urine volume,24-hour urinary protein excretion were examined at week 4,8,and 12 respectively.All the rats were sacrificed at week 12;body weight,kidney weight,and serum excretion,serum creatinine,blood urea nitroge were detected.Kidney were taken for pathological examination(HE,Mallory stain),The expressions of CTGF in rat renal were detected respectively by immunohistochemistry and in situ hybridization.Result: 24-hour urine volume,24-hour urinary protein excretion were examined at week 4,8,and 12 respectively.All the rats were sacrificed at week 12;body weight,kidney weight,and serum excretion,serum creatinine,blood urea nitroge was improved by HaikunShenxi preparation.Haikunshenxi can alleviate severe pathological changes of kidney structure in rats with DN,The expression of CTGF in the HaikunShenxi treatment group was depressed greatly.Conclusions: The overexpression of CTGF in renal tissue of diabetic rats may be one of the mechanisms of diabetic nephropathy,haikunshenxi had certainly protective effects on it.
