文题释义:
关节软骨损伤:
关节软骨损伤后其修复能力较差,并会导致进行性关节损伤,损伤不能通过常规治疗恢复。通过组织工程生物材料重塑关节软骨周围环境,促进软骨修复是目前关注的热点问题。
组织工程软骨:组织工程软骨的构建取决于合适的支架材料,丰富的细胞来源以及细胞因子的刺激作用。支架材料是构建组织工程软骨的要素之一,可以允许细胞在材料的三维微环境中生长、迁移,近年来各种生物材料已被用于软骨修复,但结果远不能实现天然软骨结构和功能。

背景:关节软骨缺损修复一直是临床上的一个难题,以往主要采用自体或异体骨软骨移植修复、软骨膜或骨膜移植等对软骨缺损组织进行修复,但由于存在来源有限、供区继发病变和免疫排斥反应等限制了其应用。近年来越来越多的研究表明,软骨组织工程修复技术对于软骨再生及修复具有重要意义。
目的:探讨关节软骨缺损修复中软骨组织工程支架材料的研究进展。
方法:由第一作者在CNKI、PUBMED和万方数据库以检索词“关节软骨缺损,支架材料,组织工程软骨,cartilage defect,scaffold,tissue engineered cartilage”检索1991至2015年有关组织工程支架材料修复关节软骨缺损的相关中文和英文文献,排除重复文献及不相关研究。
结果与结论:①根据纳入和排除标准,最终纳入48篇文献进一步分析;②软骨组织工程有着可调控、对自身组织创伤小、对损伤软骨可进行生物性修复等突出优点,组织工程支架材料是组织工程构建的成功因素,良好的组织工程支架材料应具有生物降解性及组织相容性;③目前常用的支架材料包括天然高分子材料、人工合成高分子材料,如胶原、丝素蛋白、壳聚糖等天然高分子材料,聚乳酸、磷酸三钙等人工合成材料,将不同材料的优点整合,获得优良的复合支架成为目前研究的主要方向;④因此,制备出高生物学活性的复合支架软骨组织工程支架材料成为今后的研究重点,组织工程学技术必将在关节软骨缺损修复中发挥越来越大的作用。

Abstract:

BACKGROUND: Articular cartilage repair has been a difficulty in the clinical setting, which is mainly treated with autologous or allogeneic osteochondral grafts, and cartilage periosteum or periosteum grafts. However, the limited source, secondary lesion and immunological rejection force some researchers to search for a novel treatment strategy, cartilage tissue engineering, that is of great significance for cartilage regeneration and repair.
OBJECTIVE: To investigate the tissue-engineered scaffolds for the repair of articular cartilage defects.
METHODS: The first author searched the PubMed and WanFang databases for the articles addressing tissue-engineered cartilage for articular cartilage defects published between 1991 and 2015 using the keywords “articular cartilage defect, scaffold, tissue engineered cartilage” in English and Chinese, respectively. The irrelative and repetitive literatures were excluded.
RESULTS AND CONCLUSION: Finally 48 eligible literatures were enrolled based on the inclusion and exclusion criteria. Cartilage tissue engineering possesses the advantages of controllability, little damage to tissue itself, and biological repair of injured cartilage. Tissue-engineered scaffold material is a critical factor in tissue engineering construction; therefore, it should hold biodegradability and histocompatibility. The commonly used scaffold materials include natural macromolecule materials (collagen, silk fibroin and chitosan), and synthetic polymer materials (polylactic acid and tricalcium phosphate). It is necessary to prepare composite scaffolds with high bioactivity integrate advantages of each material. The tissue engineering is bound to be a hotspot in the field of articular cartilage repair.
