| 3 | In-situ deposition of apatite layer to protect Mg-based composite fabricated via laser additive manufacturing显示文摘Biodegradable magnesium(Mg) and its alloy show huge potential as temporary bone substitute due to the favorable biocompatibility and mechanical compatibility. However, one issue deserves attention is the too fast degradation. In this work, mesoporous bioglass(MBG)with high pore volume(0.59 cc/g) and huge specific surface area(110.78 m^(2)/g) was synthesized using improved sol-gel method, and introduced into Mg-based composite via laser additive manufacturing. Immersion tests showed that the incorporated MBG served as powerful adsorption sites, which promoted the in-situ deposition of apatite by successively adsorbing Ca2+and HPO42-. Such dense apatite film acted as an efficient protection layer and enhanced the corrosion resistance of Mg matrix, which was proved by the electrochemical impedance spectroscopy measurements. Thereby, Mg based composite showed a significantly decreased degradation rate of 0.31 mm/year. Furthermore,MBG also improved the mechanical properties as well as cell behavior. This work highlighted the advantages of MBG in the fabrication of Mg-based implant with enhanced overall performance for orthopedic application. | Youwen Yang Changfu Lu Lida Shen Zhenyu Zhao Shuping Peng Cijun Shuai | 2023 | Journal of Magnesium and Alloys2023，11，2： | 1 |

| 6 | Poly(lactic-co-glycolic acid) conduit for repair of injured sciatic nerve A mechanical analysis显示文摘Tensile stress and tensile strain directly affect the quality of nerve regeneration after bridging nerve defects by poly(lactic-co-glycolic acid) conduit transplantation and autogenous nerve grafting for sciatic nerve injury. This study collected the sciatic nerve from the gluteus maximus muscle from fresh human cadaver, and established 10-mm-long sciatic nerve injury models by removing the ischium, following which poly(lactic-co-glycolic acid) conduits or autogenous nerve grafts were transplanted. Scanning electron microscopy revealed that the axon and myelin sheath were torn, and the vessels of basilar membrane were obstructed in the poly(lactic-co-glycolic acid) conduit-repaired sciatic nerve following tensile testing. There were no significant differences in tensile tests with autogenous nerve graft-repaired sciatic nerve. Following poly(lactic-co-glycolic acid) conduit transplantation for sciatic nerve repair, tensile test results suggest that maximum tensile load, maximum stress, elastic limit load and elastic limit stress increased compared with autogenous nerve grafts, but elastic limit strain and maximum strain decreased. Moreover, the tendencies of stress-strain curves of sciatic nerves were similar after transplantation of poly(lactic-co-glycolic acid) conduits or autogenous nerve grafts. Results showed that after transplantation in vitro for sciatic nerve injury, poly(lactic-co-glycolic acid) conduits exhibited good intensity, elasticity and plasticity, indicating that poly(lactic-co-glycolic acid) conduits are suitable for sciatic nerve injury repair. | Tao Yu Changfu Zhao Peng Li Guangyao Liu Min Luo | 2013 | Neural Regeneration Research2013，8，21： | 1 |

| 9 | Two Zinc(Ⅱ) Complexes Based on 7rany-(1R,2R)-cyclohexanediamine: Molecular Structure Analyses and Preparation of Composite Membrane显示文摘Two novel complexes Zn2(chda)2(TPA)Cl2(1) and [Zn(chda)2(H2O)2](TPAXH2O)2(2)[chda is a chiral ligand of trans-(1R,2R)-cyclohexanediamine, H2TPA is terephthalic acid] were synthesized at room temperature. The molecular structures of complexes 1 and 2 were identified by single-crystal X-ray diffraction measurement. The results showed that complex 1 had a binuclear structure, each Zn(Ⅱ) ion was four coordinated by two N atoms of chda, one O atom of TPA and one Cl atom, to construct a distorted tetrahedral geometry. For complex 2, the Zn(Ⅱ) ion was six coordinated by two chda molecules and two water molecules to form a ZnN4O2 octahedral geometry. Complexes 1 and 2 further extended into three-dimensional supramolecular frameworks by hydrogen-bonding interactions. Hirshfeld surface analysis and fingerprint plots were used to further analyze the contribution of diflerent intermolecular interactions. Further, a composite membrane [Zn(chda)2(H2O)2](TPA)(H2O)2/CA was prepared by adding 10%(mass fraction) of complex 2 into cellulose acetate using acetone/chloroform( V:V-1:1) as solvent. | WANG Dawei WANG Ying ZHUANG Changfu ZHAO Ping YANG Jing SHI Zhengjun | 2019 | Chemical Research in Chinese Universities2019，35，5： | 0 |
