文题释义:
医用金属材料:是一类具有良好生物相容性、优秀的力学性能以及方便加工制作的植入机体的生物金属材料,此类材料通常以支架、种植体、赝复体及外科辅助材料的形式广泛应用于骨科、牙科、整形及介入治疗中。
血管生成:血液供应是骨再生的先决条件,植入材料与病损组织相互作用,刺激内皮细胞向病损区迁移增殖,诱导血管生成相关基因的表达,促进血管生成,加快骨再生进程,改善骨再生效果。
医用金属生物材料因其出色的机械力学性能、良好生物相容性、生物安全性及可降解性能而被广泛应用于临床中,例如心血管支架、骨修复支架和口腔种植材料等,近年来逐渐成为生物组织工程研究的热点。近十年来,研究人员着力于改善植入材料的物理和化学性能以改善成骨,由于快速血管化是促进细胞增殖,成骨分化,形成新生骨组织的先决条件,因此研究金属促血管化机制,开发具有促血管生成特性的金属材料对骨组织修复与再生意义重大。镁、锌、铜、锶、钴等金属离子已经被大多数研究证明能促进血管生成,这些金属通过影响内皮细胞功能,血管生成过程中的相关因子的分泌与表达,从而参与并调节血管生成过程。镁合金因其良好的生物相容性,机械力学性能,生物可降解性而被广泛研究,成为生物材料领域的研究热点。生物可降解镁合金支架植入初期可提供一定的力学支撑,随机体的修复,组织的再生而逐渐降解,被人体吸收代谢,不需要经历二次手术取出,减少机体损伤,减轻患者痛苦和经济负担,然其过快的降解速率成为限制其临床应用的瓶颈,对镁、锌此类生物可降解金属的改性是未来研究的重点。绝大多数金属离子在一定浓度范围可产生良好的生物学效应,却在高浓度时表现出细胞毒性,因此控制金属离子在体内的释放速率是发挥其促血管化作用的关键环节。
