摘要:

文题释义:
磷酸钙陶瓷:一类由钙离子与磷酸根离子根据不同的钙磷比例混合烧结形成的陶瓷颗粒。磷酸钙陶瓷可在不添加生长因子和活体细胞的前提下,通过对其形貌调控和功能化设计,赋予其骨诱导性能。
异位成骨:具有特殊表面拓扑结构的磷酸钙陶瓷材料,植入到动物机体的非骨部位,可以诱导间充质干细胞生成骨组织的现象。通常通过异位成骨实验验证材料的成骨性能。

背景:自体骨移植、同种异体骨移植、异种骨移植等是临床中骨缺损修复的常见方式,但供体数量不足、增加手术创伤及免疫排斥反应等问题使其应用受限。而人工合成的磷酸钙陶瓷修复材料的理化结构与天然骨组织相似,其多孔微纳米形貌和表面生物活性离子使之具有优异的骨传导性及骨诱导性,在骨缺损修复治疗中有着广泛的应用前景。
目的:通过对磷酸钙陶瓷材料的常见形式、理化性能及骨诱导性能展开综述,为临床骨缺损的修复提供新的思路。
方法:在中国知网、万方数据知识服务平台、Web of Science、PubMed数据库中进行相关文献检索,中、英文检索关键词为“磷酸钙,骨修复,骨缺损,骨诱导,骨引导;bone defects,calcium phosphate ceramic,bone-repair,osteoinduction,bone inductive potentiality”,通过纳入、排除标准筛选后,最终纳入59篇文献进行综述。
结果与结论:羟基磷灰石、磷酸三钙及双相磷酸钙为最常用于骨修复的磷酸钙陶瓷材料,通过对其制备工艺、表面改性等方式不断改进,使它们具有良好的生物相容性、生物降解性及骨诱导性。通过调控其宏观结构、微纳米表面形貌(孔径、粗糙度等)、钙磷释放和蛋白吸附等特性,直接或间接地影响成骨诱导的过程;磷酸钙陶瓷与炎症细胞(单核细胞、巨噬细胞、破骨细胞等)、成骨蛋白的相互作用,导致了更多的具有骨诱导特性的表面特征形成和更高浓度的Ca2+、PO43-以及成骨细胞因子聚集,在体内外研究中均取得良好的骨诱导效果。

Abstract: BACKGROUND: Autologous bone transplantation, allograft and xenograft are common methods for bone defect repair in clinical practice, but their application is limited by insufficient donor number, increased surgical trauma and immune rejection. The physical and chemical structures of synthetic calcium phosphate ceramic repair material are similar to those of natural bone tissue, and its porous micro-nano morphology and surface bioactive ions make it have excellent osteoinduction and bone inductive potentiality, which has a wide application prospect in the repair and treatment of bone defects.
OBJECTIVE: To provide new ideas for the repair of bone defects in clinical diagnosis and treatment by reviewing the common forms, physicochemical properties and osteoinductive properties of calcium phosphate ceramic materials. 
METHODS: The literature search was performed in CNKI, Wanfang, Web of Science, and PubMed databases. The keywords were “calcium phosphate ceramic, bone-repair, bone defects, osteoinduction, bone inductive potentiality” in Chinese and English. According to the inclusion and exclusion criteria, 59 articles were finally reviewed. 
RESULTS AND CONCLUSION: Hydroxyapatite, tricalcium phosphate and biphasic calcium phosphate are calcium phosphate ceramic materials most commonly used in bone repair. Through continuous improvement of their preparation process and surface modification, they have good biocompatibility, biodegradability and bone induction. By regulating its macrostructure, micronano surface morphology (aperture, roughness, etc.), calcium and phosphorus release and protein adsorption, the osteogenic induction process is directly or indirectly affected. The interaction of calcium phosphate ceramics with inflammatory cells (monocytes, macrophages, osteoclasts) has led to more surface feature formation with osteoinductive properties and higher concentration of Ca2+, PO43- and associated factors, which has achieved good bone induction results in both in vitro and vivo studies.
