摘要:

文题释义:
肩袖腱骨愈合:肩袖由前方肩胛下肌、上方冈上肌及后方的冈下肌和小圆肌组成,是包绕在肱骨头肱骨头周围,维持肱盂关节运动和稳定的一组肌肉。理想愈合为纤维软骨组织与骨组织相连处恢复原有的4层结构,即致密纤维结缔组织、未钙化的纤维软骨、钙化的纤维软骨和骨组织。
组织工程学:从机体获取少量的活体组织,又称种子细胞,在体外进行培养扩增,然后将扩增的细胞与生物材料(支架)按一定的比例混合,形成细胞-材料复合物并植入机体病损部位,随着生物材料在体内逐渐被降解和吸收,植入的细胞在体内不断增殖并分泌细胞外基质,最终形成相应的组织或器官,从而达到修复创伤和重建功能的目的。

背景:近年来关节镜下进行肩袖修补术已经成为临床治疗肩袖损伤的“金标准”,但经肩袖修补术治疗后的术后再撕裂率却居高不下,其主要原因在于肩袖原有结构无法恢复,因此仅通过手术方法进行解剖学愈合是远远不够的。随着组织工程学的发展,越来越多的学者发现其对肩袖愈合有着巨大的优势,可以有助于激发腱骨界面有序再生,随着研究的不断深入,各类支架、种子细胞、生长因子层出不穷,具有广阔前景。但目前国内外相关综述较少,不便临床医生及相关领域学者总体了解研究近况。
目的:对近年来肩袖腱骨愈合领域研究中的组织工程学相关支架材料、种子细胞及细胞因子做一总结,以期对肩袖腱骨愈合的基础研究和临床进展起到一定的启示作用。
方法:通过计算机检索中国知网及PubMed数据库,中、英文检索词为“肩袖损伤,组织工程;rotator cuff,tissue engineering”等。对检索出的10年内文献进行筛选,排除与文题无关及质量低或重复文献,并手动纳入其他相关文献,最终对纳入的69篇文献进行结果分析。
结果与结论:组织工程在腱骨结合部位的再生领域中有着巨大的潜力。①目前的支架材料可大体分为天然材料支架、人工合成材料支架及复合材料支架3种类型,其各有优势,但复合材料支架似乎可以更好地仿生腱骨界面原有的梯度结构因此具备更大前景。②各类干细胞和生物因子的搭载也被证实可以激发损伤区域的修复潜能。然而干细胞种类的选择和各类生物因子内在分子信号通路的研究仍需进一步深入,进而明确具体的生物因子的介入时间节点及层次,达到精准诱导原有4层结构再生的目的。

Abstract: BACKGROUND: In recent years, arthroscopic rotator cuff repair has become the “gold standard” of clinical treatment. However, the rate of postoperative retears after rotator cuff repair remains high, mainly because the original rotator cuff structure cannot be restored. Therefore, anatomical healing through surgery alone is not sufficient. With the development of tissue engineering, more and more scholars have found that it has great advantages for rotator cuff healing and can help stimulate the orderly regeneration of the tendon bone interface. As scholars continue to go deeper and deeper, various types of scaffolds, seed cells, and growth factors have emerged, which have great prospects. However, there are few related reviews at the domestic and international levels, which makes it inconvenient for clinicians and scholars in related fields to understand the recent status of research in general.  
OBJECTIVE: To provide a summary of recent research on scaffold materials, seed cells, and cytokines related to tissue engineering in the field of rotator cuff tendon bone healing, with the aim of shedding light on basic research and clinical progress in rotator cuff tendon bone healing.
METHODS: The search terms “rotator cuff injury, tissue engineering” were searched in English and Chinese by computer in PubMed and CNKI databases. The literature retrieved within 10 years was screened to exclude irrelevant, low quality or duplicate literature, and other relevant literature was included manually. Eventually, 69 papers were included for result analysis.  
RESULTS AND CONCLUSION: Tissue engineering has a great potential in the field of regeneration of tendon-bone union sites. (1) Current scaffold materials can be broadly classified into three types (natural material scaffold, synthetic material scaffold, and composite material scaffold), each with its own advantages. However, composite scaffolds seem to be more promising as they can better mimic the original gradient structure of the tendon-bone interface. (2) The pigmentation of various types of stem cells and biologic factors has also been shown to stimulate the repair potential of damaged areas. Moreover, the selection of stem cell types and the study of the intrinsic molecular signaling pathways of various biologic factors still need to be further investigated, so as to clarify the time point and level of intervention of specific biologic factors and achieve the purpose of precisely inducing the regeneration of the original four-layer structure.
