背景：纳米羟基磷灰石在骨修复替代材料中有明显优势，但骨诱导活性低、力学性能差等缺陷限制了其临床应用。为克服弊端，国内外学者从仿生学等角度出发，以纳米羟基磷灰石为基础，掺杂、复合有机或无机材料，得到多种仿生复合材料。 　　目的：综述纳米羟基磷灰石/聚酰胺66复合材料的研究及应用进展。 　　方法：应用计算机检索1987年1月至2012年12月 PubMed 数据库相关文章，检索词为“nano， hydroxyapatite ，polyamide 66”。同时，计算机检索1987年1月至2012年12月中国期刊网全文数据库相关文章，检索词为“纳米，羟基磷灰石，聚酰胺66”。共检索到文献93篇，最终纳入符合标准的文献56篇。 　　结果与结论：纳米羟基磷灰石/聚酰胺66复合材料具有良好的热稳定性、生物力学性能及生物相容性。目前，纳米羟基磷灰石/聚酰胺66复合材料研究及引用主要集中于人工椎体、人工椎板及椎间融合器等，并取得了良好临床治疗效果，但仍有很多问题尚需要解决，如诱导成骨、降解情况都缺少长期而详尽的随访资料，而且目前主要是通过细胞学、组织学等方面来评价其生物安全性，尚未涉及到分子水平。

BACKGROUND:The nano-hydroxyapatite has obvious advantages in bone repairing and reconstruction, but its clinical application is limited for its low osteoinductive activity and poor mechanical properties. To overcome these defects, researchers, based on the bionics principles, composite nano-hydroxyapatite with inorganic or/and organic materials to get various biomimetic composite materials. OBJECTIVE:To review the research and application of nano-hydroxyapatite/polyamide 66 biocomposites. METHODS:A computer-based search of PubMed database was undertaken with the keywords of“nano, hydroxyapatite, polyamide 66”in English to retrieve the relevant articles published from January 1987 to December 2012. Simultaneously, the relevant articles between January 1987 to December 2012 were searched in CNKI database with the key words of“nano, hydroxyapatite, polyamide 66”in Chinese. A total of 93 literatures were retrieved, and final y 56 standard literatures were included. RESULTS AND CONCLUSION:The nano-hydroxyapatite/polyamide 66 biocomposites have appropriate thermostability and mechanical properties as wel as good biocompatibility. So far, the research and application of nano-hydroxyapatite/polyamide 66 biocomposites mainly focus on artificial vertebral body, lamina, and cage. The satisfactory clinical effects of the biocomposites show their broad clinical application prospects. However, there are stil many problems to be solved. For example, there are no detailed long-term fol ow-up data concerning osteogenic induction and degradation. Additional y, current studies focus on the bio-safety of materials in the aspects of cytology and histology rather than at the molecular level.
