【Abstract】Aim To study the therapeutic effect of recombinant human acidic fibroblast growth factor (rh-aFGF) carbomer 940 gel in the treatment of skin wound healing in type I diabetic rats. Methods Two types of skin trauma models, namely, full-thickness wound and scalded wound, were established in a model of type I diabetes mellitus using STZ-induced SD rats. The rats were divided into control group, vehicle group, 90 AU rh-aFGF gel group and 270 AU rh-aFGF gel group in each skin wound models. The wound area and wound healing rate were used to evaluate the therapeutic effect. The growth of fibroblasts, fibrocytes, collagen fibers and vessel capillaries in the wound was observed using HE staining and analyzed by semiquantitative score. Results The rh-aFGF carbomer gel significantly reduced the traumatic area as well as promoted the wound healing rate of the skin trauma model of SD rats of type I diabetes mellitus (P < 0.05). HE staining showed that rh-aFGF carbomer gel significantly promoted the pathological score of fibroblasts and collagen fibers (P < 0.05). Conclusions rh-aFGF carbomer gel might play a protective role in micro-environment of wound and rh-aFGF, which could benefit for proliferation of fibroblasts and collagen, therefore promoting the healing process of skin wound in SD rats with type I diabetes mellitus, and it might be expected to be a new preparation for the treatment of chronic trauma in diabetes mellitus.
