ObjectiveTo investigate the effort of MHA-bBMP implantation combined with limited contacted titanium net duct fixation on femoral shaft bone defect of rabbit.Methods48 rabbits were divided into the experimental group (treated with bionic bone MHA-bBMP plus titanium net duck) and control group (treated with iliac autograft plus titanium net duct) with 24 animals in each group. The rabbit femoral shaft bone defect model was established by cutting 10 mm bone fragment off. After operation, bionic bone MHA-bBMP/iliac autograft was implanted into bone defect area and fixed with limited contacted titanium net duck. The general condition, serum alkaline phosphatase, X-ray, histopathologic examination and electron microscope were performed.ResultsThe fixation stability of titanium net duck in two groups was good. The bone defect of two groups was repaired. The results of phosphatase, X-ray, histopathologic examination and electron microscope of two groups were not significantly different.ConclusionBionic bone MHA-bBMP is a high bioactivity substitute, and can obtain therapeutic effect equal to iliac autograft when repairing rabbit's femoral shaft defect.

Objective: In order to reveal the mechanisms of rh-endostatin and its suppression effect on HUVECs at different activating levels. Methods: Three types of HUVEC were prepared. We detected the ex-pression of CD105 and CD62E on the surface of adhering HUVEC, HUVEC of exponential phase of growth, and HUVEC activated with TNF-alpha. The effect of endostatin on these three types of HUVEC was indicated by the variation in the expression of CD105 and CD62E on the cells. The relationship of the changes in cell markers with the time and the concentration of endostatin was analyzed by SPSS 11.5. Results: The expres-sion of CD105 was correlated with time and dose of endostar in all groups. The expression of CD62E was cor-related with the dose of endostar in HUVEC treated with TNF-α for 24h. Conclusion: Endostatin of a certain dose can inhibit the activation of endothelial cells but it cannot induce cell apoptosis.
