Results of screening for diabetic blood stasis syndrome rats. After injection of STZ into the SD rats by intraperitoneal route, the blood glucose levels (a) and body weight (b) of all SD rats were measured every week. Then, to screen for diabetic rats with blood-stasis syndrome, the cataract-related symptoms (c) and blood serum (d) were observed and photographed. e The pancreas of some rats in normal (a, d), diabetes (b, e) and Xuefu Zhuyu decoction treatment (c, f) groups were acquired, the pancreas islets structure was inspected by H&E staining. The magnification is 100 for a–c; 200 for d–f. The data were expressed as mean ± SD, P value less than 0.05 was considered statistically significant, ‘ns’ indicates no significance, *P < 0.05, **P < 0.01, ***P < 0.001
