1Adenovirus-mediated human brain-derived neurotrophic factor gene-modified bone marrow mesenchymal stem cell transplantation for spinal cord injury显示文摘Rat bone marrow mesenchymal stem cells expressing brain-derived neurotrophic factor were successfully obtained using a gene transfection method,then intravenously transplanted into rats with spinal cord injury.At 1,3,and 5 weeks after transplantation,the expression of brain-derived neurotrophic factor and neurofilament-200 was upregulated in the injured spinal cord,spinal cord injury was alleviated,and Basso-Beattie-Bresnahan scores of hindlimb motor function were significantly increased.This evidence suggested that intravenous transplantation of adenovirus-mediated brain-derived neurotrophic factor gene-modified rat bone marrow mesenchymal stem cells could play a dual role,simultaneously providing neural stem cells and neurotrophic factors.ChangshengWang Jianhua Lin Chaoyang Wu Rongsheng Chen 2011Neural Regeneration Research2011,6,16:2
218-DOF Triangular Quasi-Conforming Element for Couple Stress Theory显示文摘The basic idea of quasi-conforming method is that the strain-dis-placement equations are weakened as well as the equilibrium equations.In this paper,an 18-DOF triangular element for couple stress theory is proposed within the framework of quasi-conforming technique.The formulation starts from truncated Taylor expansion of strains and appropriate interpolation functions are chosen to calculate strain integration.This element satisfies C0 continuity with second order accuracy and weak C1 continuity simultaneously.Numerical examples demonstrate that the proposed model can pass the C0??1 patch test and has high accuracy.The element does not exhibit extra zero energy modes and can capture the scale effects of microstructure.Xiangkui Zhang ChangshengWang Ping Hu 2016Computer Modeling in Engineering & Sciences2016,,6:0
