Objective To investigate the effects of local application of NGF combined with Insulin on wound healing with Ⅱ degree deep scald and the expression of HIF-1α and VEGF in diabetic rats. Methods 60 male Wistar rats were used in the study by intraperitoneal injection of streptozotocin (STZ). Deep partial thickness scalding was engendered on the back of the rats after one month. Then these rats were random divided into group B (scalding of the rats with diabetes, n = 15), C (insulin control, n = 15), D ( NGF control, n = 15) and E ( NGF and insulin supplementation, n = 15). And group A ( nomal control,n = 15) was created by normal rats of partial thickness scalding. The wound area, wound healing rate, and grey of HIF-1α and VEGF immunohistochemistry staining were determined on the 3rd, 7th, 15th, and 21st day post scalding days (PSDs). Results Compared to those in groups A, B, C and D, the wound healing rate in group E increased significantly since the 7th PSD [(25.33 ± 2. 32 ) %, P ＜ 0.05]. The wound healing rate in group C and D increased significantly compared with group B [( 16. 68 ± 1.95 ) %, ( 18.29±1. 70)%, P ＜0.05]. Compared to group A, the group D increased significantly since the 15th PSD [(54. 84 ±3.60)%, P ＜0. 05]. The expression of HIF-1α and VEGF in group E began to increase slower than other groups after the 7th day ( P ＜0. 05 ). Conclusion Local application of NGF combined with Insulin could be beneficial to the regeneration of capillary vessel in the burn wounds of the rats with diabetes,as well as to accelerate wound healing by redress anoxia and decrease the expression of HIF-1α and VEGF.
