Here we have reported a female patient who suffered wound rupture due to early post-operation mobilization and weight-bearing. The wound dehiscence was successfully managed by applying recombinant basic fibroblast growth factor-2 and anti-infective treatment without removing prosthetic joint.展开更多

Methods: The complex of rhbFGF and bovine type I collagen was implanted into the mandibular fracture site under periosteum of the animal. The whole mandible was harvested at 7, 14, 28, 56 and 84 days respectively after operation. The expression of proliferating cell nuclear antigen (PCNA) in callus was examined with immunohistochemical staining. Results: PCNA-positive cells in callus in the rhbFGF-treated group on days 7 and 14 were more than that in the control group (P< 0.01 ). Conclusions: It indicates that rhbFGF can stimulate cell proliferation during mandibular fracture healing in rabbits.展开更多

Rat osteoblasts were transfected with pCD-rbFGF plasmid by lopofectin mediated gene transfer, the transient expression was detected by streptavidin-biotin-enzyme complex (SABC) method. It was observed that the expression of rat bFGF gene was detected 72 h after transfected distinctly. Basic fibroblast growth factor gene therapy is a method of potential for a wide array of orthopedic diseases.展开更多
