Abstract Objective To investigate the effect of recombinant human acidic fibroblast growth factor (RhaFGF) on healing of diabetic rats with refractory skin ulcers, and to further study the effect and mechanism of RhaFGF on the healing of diabetic rats with refractory skin ulcers. Methods The diabetic rat model of skin ulcer was established. A total of 28 rats were randomly divided into control group and RhaFGF group. The control group was treated with topical saline, and RhaFGF group was treated with topical application of RhaFGF. The wound area was recorded on the seventh day and the fourteenth day, and the new granulation tissue in the skin ulcer area of rats was collected. Superoxide dismutase (SOD), malondialdehyde (MDA), platelet endothelial cell adhesion molecule (CD31), functional antigen Ki-67 (Ki-67) and pathological sections were examined to evaluate the therapeutic effect of RhaFGF in treating diabetic refractory ulcers. Results On day 7 and 14 of treatment, the wound area of the RhaFGF group was smaller than that of the control group, and the difference was statistically significant (P<0.05). MDA content in the RhaFGF group was lower than that in the control group, and the difference was statistically significant (P<0.05). SOD activity in the RhaFGF group was higher than that in the control group, and the difference was statistically significant (P<0.05). The positive expression rate of CD31 in the RhaFGF group was higher than that in the control group, and the difference was statistically significant (P<0.01). The positive expression rate of Ki-67 in the RhaFGF group was higher than that in the control group, and the difference was statistically significant (P<0.01). Histopathological examination showed that the number of new capillaries, fibroblasts and collagen expression increased in RhaFGF group compared with before treatment. Conclusion RhaFGF promotes oxidative stress of diabetic refractory ulcers, increases the production of capillaries and fibroblasts in ulcerated tissues, and significantly increases the level of epithelial regeneration, thereby demonstrating the repair effect on diabetic ulcers.
