摘要:

文题释义:
成骨:小面积的骨缺损发生后,会自动实现骨再生愈合的过程,其中包括间充质干细胞的募集、生长因子的释放、新生血管的长入、成骨细胞的增殖分化等。
钙离子:细胞内的第二信使,也是骨主要成分,不仅对间充质干细胞、成骨细胞、破骨细胞的增殖分化及新血管生长和生长因子释放产生重要作用,还可通过影响骨缺损断端处血凝块的结构影响成骨。
背景:大节段性骨缺损的再生修复仍是临床骨科医生的巨大难题之一,钙离子不仅对骨细胞发育及血管再生和生长因子释放至关重要,还可通过影响局部血凝块的结构来调控成骨活动。
目的:综述国内外相关文献,总结钙离子与成骨之间的关系,了解钙离子在成骨中的作用机制,为新的成骨策略提供理论参考。
方法:中文以“钙离子,成骨,间充质干细胞,成骨细胞,破骨细胞,血管,血凝块”检索 CNKI、万方、维普数据库;英文以“calcium,osteogenesis,mesenchymal stem cell,osteoblasts,osteoclasts,neovascularization,blood clots”检索PubMed数据库,收录2000年1月至2021年1月时间段与钙离子在成骨中的作用机制相关的文献,并通过阅读摘要进行初筛,最终共纳入94篇文章进行综述分析。
结果与结论:钙离子不仅可以调控骨修复阶段中各种细胞(间充质干细胞、成骨细胞和破骨细胞)的增殖分化,还能通过促进骨缺损处新血管生成并促进生长因子释放来调节成骨。最近研究还发现,骨缺损处血凝块的结构对早期骨愈合产生着重要影响,而钙离子可以通过调节纤维蛋白的聚合过程来调控血凝块的结构。

Abstract: BACKGROUND: Large-segmental bone defect healing still remains as a critical challenge for orthopedic surgeons. Calcium ion is not only vital for the development of bone cells, angiogenesis and release of growth factors, but also can regulate osteogenesis by affecting the structure of blood clots.
OBJECTIVE: To review relevant domestic and foreign literatures, summarize the relationship between calcium ion and osteogenesis, and further understand the mechanism of calcium ion in osteogenesis, providing theoretical reference for new osteogenic strategies.
METHODS: CNKI, WanFang, VIP, and PubMed databases were searched for literatures regarding osteogenic role of calcium ions published from January 2000 to January 2021. Key words were “calcium, osteogenesis, mesenchymal stem cell, osteoblasts, osteoclasts, neovascularization, blood clots” in Chinese and English, respectively. Finally, 94 articles were included for review.
RESULTS AND CONCLUSION: Calcium ions are not only involved in the proliferation and differentiation of various osteogenesis-related cells (such as mesenchymal stem cells, osteoblasts, osteoclasts), but also involved in the osteogenesis by promoting angiogenesis and release of growth factors at defect sites. Recent studies have found that altered structure of blood clot at defect sites has a crucial impact on early bone healing, and calcium ions can regulate the structure of blood clots by regulating polymerization of fibrin. 

Key words: calcium ion, osteogenesis, osteocyte, blood clot
