摘要:


文题释义:

羟基磷灰石:是人体骨组织的主要无机质成分,其钙/磷比为1.67,与自然骨组织相似,可与人体骨组织通过羟基键合,且有一定的降解性,可释放钙、磷离子刺激或诱导骨组织生成,促进骨缺损局部修复,具有良好的生物相容性,但其脆性高、降解速度慢及骨诱导性、成血管活性等较弱,限制了其在临床上的单独使用。
聚合物包括天然聚合物和人工合成聚合物,在结构上与细胞外基质类似,具有良好的生物相容性、可调控的降解性、细胞因子和药物缓释性、骨传导性,常与其他材料复合制备新材料用于细胞因子和药物的缓释、骨组织缺损的修复等。


背景:羟基磷灰石是骨组织的主要无机成分,聚合物可仿生细胞外基质的结构和功能,两者的复合材料得到了广泛研究。

目的:总结羟基磷灰石复合聚合物材料用于骨组织修复的研究现状。
方法:检索2010年1月至2023年4月PubMed、Web of Science、中国知网及万方数据库收录的相关文献,中文检索词为“羟基磷灰石,聚合物,复合材料,可降解性,骨缺损,骨修复”,英文检索词:“hydroxyapatite,polymer,composites,degradability,bone defect,bone repair”,最终纳入75篇文献进行综述分析。

结果与结论:常与羟基磷灰石复合用于骨组织修复的聚合物包括天然聚合物(胶原、壳聚糖、海藻酸盐、丝素蛋白、纤维素、透明质酸、聚羟基丁酸酯等)和合成聚合物(聚乳酸、聚乳酸-羟基乙酸共聚物、聚已内酯、聚氨基酸、聚乙烯醇等)。羟基磷灰石/聚合物复合材料较纯羟基磷灰石的机械性能、骨诱导性得到了提高,羟基磷灰石与聚合物复合可制成多孔支架、水凝胶、涂层等用于骨修复。羟基磷灰石/聚合物复合材料因其仿生细胞外基质结构和功能可缓释负载的药物和细胞因子,加速骨重建。基于骨缺损原因的多样性以及骨修复为多种生物因子和蛋白共同参与的复杂连续过程,机械性能与骨组织匹配、降解过程与骨修复同步、高效成骨成血管的修复材料有待进一步研究。

Abstract: BACKGROUND: Hydroxyapatite is the main inorganic component of bone tissue. The polymer has the structure and function of a biomimetic extracellular matrix. The composites of hydroxyapatite and polymer have been widely studied.
OBJECTIVE: To summarize the research status of hydroxyapatite composite polymer materials for bone tissue repair.
METHODS: The articles collected in PubMed, Web of Science, CNKI and WanFang databases were searched from January 2010 to April 2023. The Chinese and English search terms were “hydroxyapatite, polymer, composites, degradability, bone defect, bone repair”. Finally, 75 articles were included for review.
RESULTS AND CONCLUSION: Polymers often used in composite with hydroxyapatite for bone tissue repair include natural polymers (collagen, chitosan, alginate, serine protein, cellulose, hyaluronic acid,and polyhydroxybutyrate) and synthetic polymers [polylactic acid, polylactic acid-hydroxyacetic acid copolymer, poly(has-lactide), poly(amino acid) and poly(vinyl alcohol)]. The mechanical properties and osteoinductivity of hydroxyapatite/polymer composites were improved compared with pure hydroxyapatite. Hydroxyapatite composite with polymers can be made into porous scaffolds, hydrogels, and coatings for bone repair. Hydroxyapatite/polymer composites can accelerate bone reconstruction with a slow release of loaded drugs and cytokines due to their bionic extracellular matrix structure and function. Based on the diversity of causes of bone defects and the fact that bone repair is a complex continuous process involving multiple biological factors and proteins, repair materials with mechanical properties matching bone tissue, degradation processes synchronized with bone repair, and efficient osteogenesis and vascularization need to be further investigated.

Key words: hydroxyapatite, polymer, composite, biomaterial, bone repair, bone tissue engineering, bone defect
