文题释义:
脱钙骨基质:主要取自于同种异体骨,包含胶原蛋白(主要为Ⅰ型和Ⅳ型)、非胶原蛋白、生长因子、少量磷酸钙及细胞碎片等,作为骨修复基质和传递生物活性剂的载体,在经过脱钙及人工处理后,暴露和释放了骨形态发生发生蛋白,使其具有促进骨再生的骨诱导性质。
生长因子:指诱导成骨的生长因子,可调节细胞的增殖分化和细胞外基质的合成,这种作用主要通过早期自分泌和旁分泌的方式,提高成骨细胞的增殖速度和活性,显著增强骨组织的再生能力。
 
 
背景:各种材料和组织工程骨研究已取得了重大进展,不同材料均展示出强大的骨缺损修复能力。
目的:概述骨缺损修复材料的研究现状与进展。
方法:应用计算机检索PubMed、PMC、中国生物医学文献数据库、中国知网、万方数据库检索2007年6月至2017年6月关于骨缺损修复材料方面的文献,以“biomaterials,bone repair materials,bone substitute,bone tissue engineering,bone defect,bone repair”为英文检索主题词,以“生物材料,骨修复材料,骨替代物,骨组织工程,骨缺损,骨修复”为中文检索主题词。排除无关和重复性研究,共保留66篇文献进行总结与归纳。

结果与结论:目前主要的骨缺损修复材料包括自体骨、同种异体骨、异种骨、脱钙骨基质、生物陶瓷、金属材料、高分子材料、组织工程骨及相关衍生的复合材料。不同材料均存在一定的优缺点,因此在临床应用时需结合材料特性做出优化选择。虽然骨缺损修复材料的相关研究已取得了重大进展,但如何实现材料的高度仿生,优化细胞的黏附及迁徙,精确调控相关基因和生长因子的表达和释放,验证临床应用的安全性及循证医学的证据支持等,仍然是学者们未来需要继续深入研究和解决的问题。

Abstract:

BACKGROUND: Great development has been made in the research of various repair materials and tissue-engineered bone, and different materials exhibit a strong ability to repair bone defects.

OBJECTIVE: To review the research status and progress of repair materials for bone defects.
METHODS: PubMed, PMC, CBM, CNKI and WanFang databases were used online to retrieve the relative articles regarding repair materials for bone defects published from June 2007 to June 2017. The key words were “biomaterials, bone repair materials, bone substitute, bone tissue engineering, bone defect, bone repair” in English and Chinese, respectively. Finally, 66 eligible articles were included, while the unrelated and repeated ones were excluded.
RESULTS AND CONCLUSION: The main repair materials for bone defects include autologous bone, allogeneic bone, xenogeneic bone, demineralized bone matrix, bioceramics, metal materials, polymer materials, tissue-engineered bone and relative derived composites. Different materials have shown certain advantages and

disadvantages. Clinicians should make an optimal choice in view of the characteristics of materials. Although there is a great progress in the studies of repair materials for bone defects, further investigations are warranted on how to produce highly biomimetic materials, optimize cell adhesion and migration, precisely control the expression and release of related genes and growth factors, validate clinical safety, and provide medical evidence in clinical practice.
