Methods Fourty male Wistar rats were randomly divided into Crucian carp decoction group、Irbesartan group、Nephrosis group，and Control group. Nephrosis of rats were induced by a single tail intravenous injection of adriamycin 6.2mg/kg body weight.The rats were administered once oral gavage of Crucian carp decoction group for 9 weeks, urinary protein was checked each week.All rats were killed at week 9.Histological changes were observed by light microscopy and blood biochemical indices were detected. IL-17、IL-23、IL-1β、CXCR2IL-17、IL-23、IL-1β Rats in Crucian carp decoction group had a higher level of albumin compared with Nephrosis group (P=0.03),a lower level compared with Control group(P=0.01) and the expression of IL-17、IL-23、CXCR2 in ki
