摘要:

文题释义:
静电纺丝技术:将聚合物溶液或熔体置于几千至上万伏的高压静电下,聚合物液滴在电场力的效果下形成泰勒锥,当电场力足够大时,聚合物液滴克服外表张力从而构成喷发细流,细流在喷发进程中溶剂蒸腾或固化,最终落在接收设备上,最终形成直径为数百纳米至数微米的纤维结构,被广泛应用于组织工程及其他领域。
肩袖:附着、包绕于肱骨头的一组肌腱,起到了活动肩关节并维持肩关节稳定的作用。

背景:应用静电纺丝技术制备的纳米纤维结构与天然肌腱组织细胞外基质相似,并具有纳米纤维本身的固有特性。
目的:综述各类静电纺丝支架的构成方式及其在肌腱和肩袖组织工程中的应用。
方法:通过中国知网、万方、PubMed、Web of Science数据库进行在线文献检索,检索时间范围为2000-2020年。中、英文关键词为“静电纺丝,纳米纤维,肌腱,肩袖,组织工程;electrospun or electrospinning,nanofibers,tendon,rotator cuff,tissue engineering”,纳入与静电纺丝、肩袖、肌腱及组织工程有关的文章,最终对69篇文献进行分析。
结果与结论:静电纺丝的支架构建在材料选择、纤维构成及改性与载药上的策略多种多样。天然材料与合成材料各有优势,两种及以上材料的混合电纺能产生独特的性质。非取向纤维具有更好的拉伸长度,取向纤维在弹性模量、断裂强度及生物相容性上均具有优势。改性、载药等手段均能使纳米纤维支架获得特殊的性质,有助于肩袖和肌腱损伤修复。

Abstract: BACKGROUND: The structure of nanofibers prepared by electrospinning technology is similar to that of natural tendon tissue and extracellular matrix, and has the inherent characteristics of nanofibers. 
OBJECTIVE: To review the structure of various electrospinning scaffolds and their application in tendon and rotator cuff tissue engineering systematically.
METHODS: PubMed, CNKI, Wanfang, and Web of Science databases were searched for relevant articles published from 2000 to 2020 with the search terms of “electrospun, tendon, rotator cuff, tissue engineering” in both English and Chinese. Totally 69 articles were finally included for analysis.
RESULTS AND CONCLUSION: There are various strategies in manufacturing electrospun scaffolds. Scaffolds differ from material selection, fiber composition, modification and drug loading and many other aspects. Natural and synthetic materials both have their own advantages. Hybrid electrospinning of more than two kinds of materials can produce unique properties. Although non-aligned fibers have better tensile length, aligned fibers have advantages in elastic modulus, fracture strength and biocompatibility. Nanofibrous scaffolds can also be used in drug release, and it may have a modified characteristic and improve rotator cuff and tendon healing.

Key words: bone, material, electrospinning, nanofiber, tissue engineering, rotator cuff, tendon, review
