摘要
背景:在周围神经修复方面,神经导管已由传统的无内支架结构逐步走向内部结构的创新,以构建更加有利于周围神经再生的具有内支架结构的神经导管。因此对于神经导管内部支架结构的全面了解是十分必要的。目的:综述近年来神经导管内支架在修复周围神经缺损方面的应用。方法:以"nerve conduit/conduits/scaffolds/scaffold/channel/channels,internal scaffolds/scaffold,nerve regeneration/repair,hydrogel,acellularized/decellularized nerve"或"神经导管,内支架,周围神经修复,凝胶,去细胞神经"为检索词,应用计算机分别在PubMed数据库和中国知网、万方数据库、中国生物医学文献数据库,检索2009年1月至2015年12月与神经导管内支架相关的文章,对纳入的47篇符合标准的文献进行综述。结果与结论:具有内支架结构的神经导管相较于传统的无内支架结构的神经导管在修复周围神经缺损方面有明显优势,可以更加有效的支持、引导和促进周围神经的再生与功能的恢复,有些神经导管内支架复合种子细胞、神经营养因子、细胞外基质后修复效果更佳,甚至与自体神经移植具有相似的修复效果。
BACKGROUND： To enhance peripheral nerve regeneration, the focus on the development of nerve conduits has been shifted from conventional conduits without internal structure to novel conduits with internal stuucture.Therefore, a comprehensive understanding of the internal structure of nerve conduits is necessary.OBJECTIVE： To review the application of tissue-engineered nerve conduits with internal structure in nerve regeneration.METHODS： A computer-based research of CNKI, WanFang, SinoMed and PubMed databases was performed to retrieve relevant literatures about the tissue-engineered nerve conduits with internal structure published from January 2009 to December 2015, using the keywords of ＂nerve conduit/conduits/scaffolds/scaffold/channel/channels, internal scaffolds/scaffold, nerve regeneration/repair, hydrogel, acellularized/decellularized nerve＂ in Chinese and English,respectively. Forty-seven eligible literatures were included for overview.RESULTS AND CONCLUSION： The novel nerve conduits with internal structure have many advantages over conventional conduits without internal structure, which can support, guide, promote peripheral nerve regeneration and functional recovery, especially, when modified with seed cells, neurotrophic factors or extracellular matrix, can achieve more effective results comparable to autologous nerve grafts.
