OBJECTIVE: To observe the expressions of transforming growth factor β 1 (TGF-β 1) and basic fibroblast growth factor (bFGF) induced membrane by Masquelet technique in rats treated with glycoside of short-horned epimedium Herb, and to explore the effect of glycoside of short-horned epimedium Herb on Masquelet induced membrane.
METHODS: Sixty 3-month-old male Wistar rats were randomly divided into 3 groups with 20 rats in each group; a tibial bone defect (6 mm in length) model was established. The blank group (group A) was not treated; the control group (group B) and the experimental group (group C) were filled with vancomycin antibiotic bone cement in the drawing stage, and the bone cement was completely solidified. Group C was given perfused flavonoids glycoside of short-horned epimedium Herb (10 μmol/L) by gavage once a day (0.3 mL) from 1 day after operation, and groups A and B were given the same amount of normal saline by gavage. After operation, the recovery and wound healing of experimental animals were observed; at 4 weeks after operation, X-ray film was taken to observe the recovery of bone defect of proximal tibia; at 6 weeks after operation, the bone defect was observed, and the morphological changes and vascularization degree of granulation tissue and induction membrane tissue were observed; the expressions of TGF-β 1 and bFGF were observed by immunohistochemistry staining and ELISA detection.
RESULTS: The bone defect models of the 3 groups were established successfully, and there was no abnormality after operation. The incisions healed by first intention after operation. At 4 weeks after operation, X-ray films of proximal tibial defect showed that there was obvious space in group A, while bone cement was filled and Kirschner wire fixation was good in groups B and C. At 6 weeks after operation, the gross observation showed that the granulation tissue was filled in the defect area in group A; transparent membrane was formed in groups B and C, and microvessels were seen in some areas, and the microvessels in group C were significantly more than those in group B. Immunohistochemical staining showed that the expressions of TGF-β 1 and bFGF were negative in group A, but they were expressed in groups B and C, and the expressions of TGF-β 1 and bFGF in group B were significantly less than those in group C. ELISA detection showed that the expressions of TGF-β 1 and bFGF in group C were significantly higher than those in groups A and B ( P<0.05), but there was no significant difference between groups A and B ( P>0.05).
CONCLUSION: Glycoside of short-horned epimedium Herb can significantly increase the expressions of TGF-β 1 and bFGF, accelerate the process of osteogenesis, and contribute to bone shaping and reconstruction.
