文题释义:
可吸收防粘连生物材料:
可吸收生物材料具备良好的组织相容性、良好通透性和生物可吸收性,具有屏障作用、止血及抑制胶原产生和炎症反应的作用。目前临床上可吸收医用防粘连材料主要有透明质酸、聚乳酸、胶原蛋白、纤维蛋白胶等,聚乳酸、几丁糖和透明质酸。可吸收生物材料预防肌腱粘连的机制在于屏障作用,将其置于创面与周围组织之间,阻止成纤维细胞、纤维蛋白及炎性渗出物的浸润漫延,从而防止在创面和周围组织之间形成粘连,能在整个炎性渗出及粘连形成期发挥隔离作用。
肌腱粘连:肌腱修复的主要方法包括修复和重建,粘连形成是肌腱损伤修复后的常见并发症。肌腱粘连是机体的一种纤维增生性炎症反应,机体在物理、化学和生物等各种因素刺激下,释放组胺、缓激肽等血管活性物质及细胞因子,使局部毛细血管通透性增加,导致充血、水肿,并形成炎性渗出,渗出液中纤维蛋白原和纤维蛋白析出并附着于浆膜,形成网络状物,后者含有多核细胞和炎性细胞,继而成纤维细胞出现其中,产生胶原纤维并增殖、机化,形成粘连。肌腱粘连影响修复后的肌腱功能,已成为运动性肌腱损伤修复失败的主要原因。多种外科技术、药物等都已被应用于肌腱粘连的预防,生物可吸收材料是预防肌腱粘连的重要方法。

背景:运动性肌腱损伤后,重建肌腱粘连是肌腱损伤修复失败的主要原因,理想的防止肌腱粘连材料对肌腱损伤重建有重要作用。
目的:分析可吸收医用防粘连材料在抑制运动性肌腱损伤重建后粘连的临床效果及性能特点。
方法:应用计算机检索CNKI和PubMed数据库1988至2015年有关半月板损伤修复和组织工程技术应用方面的文献,中文检索关键词为“肌腱修复、肌腱粘连、可吸收生物材料”,英文检索关键词为“tendon Repair,tendon adhesion,absorbable biomaterials”。
结果与结论:可吸收医用防粘连材料研究和临床应用均已取得显著成果。目前临床上可吸收医用防粘连材料主要有透明质酸、聚乳酸、胶原蛋白、纤维蛋白胶等,具有良好的生物相容性,能够在体内降解吸收,临床实施操作简单,能完全覆盖创伤表面,其作用机制主要有降低胶原纤维的产生、屏障隔离、加速止血、抗菌消炎等,可有效减少肌腱损伤重建后粘连,促进肌腱愈合。但他们又有各自的局限性,透明质酸在体内作用时间短,而且有免疫原性;聚乳酸最终分解物为乳酸小分子,可引起无菌性炎症;胶原蛋白、纤维蛋白胶的生物相容性、活性都存在着很多不足。

Abstract:

BACKGROUND: After sports tendon injury, tendon adhesion is the main reason for the failure to repair tendon injury. So, an ideal anti-adhesion material plays an important role in the tendon reconstruction.

 

OBGECTIVE: To analyze the clinical effect and features of absorbable medical biomaterials in inhibiting tendon adhesion after repair of sports tendon injury.  

 

METHODS: CNKI and PubMed database were retrieved by the first author using computer to search relevant articles about meniscal repair and tissue engineering technology published from 1988 to 2015. The key words were “tendon repair, tendon adhesion, absorbable biomaterials” in Chinese and English, respectively.  

 

RESULTS AND CONCLUSION: Basic and clinical studies on absorbable anti-adhesion materials have achieved remarkable results. Currently absorbable anti-adhesion materials include hyaluronic acid, polylactic acid, collagen and fibrin glue, which have good biocompatibility and can be absorbed and degraded in vivo. With simple clinical implementation, these materials can completely cover the wound surface. The main mechanisms are as follows: reducing the generation of collagen fibers, isolation barrier, accelerating hemostasis, antisepsis and anti-inflammation, thereby effectively reducing reconstructed tendon adhesion and promoting tendon healing. But they have their limitations: hyaluronic acid has short acting duration in vivo and immunogenicity; polylactic acid eventually is decomposed into small molecules that can cause aseptic inflammation; collagen and fibrin glue both have certain shortcomings in biocompatibility and activity.
