摘要:

文题释义:
难愈性创面:创面愈合是一个完整、复杂的动态生物学过程,其可分为炎症反应期、组织增殖期和组织重塑期3个阶段,当某一阶段失控则会导致组织损伤无法得到正常的修复,形成难愈性创面。难愈性创面多是在各种潜在性疾病的基础上形成的,例如糖尿病、血管功能不全、烧伤、血管炎及辐射等,同时创面持续的炎症状态会产生级联反应,并使不愈合的状态持续下去。
间充质干细胞:是一类具有自我更新能力的多能干细胞,来源广泛,具有分化、低免疫原性和免疫调节等优点。间充质干细胞应用于组织修复是近来研究的热点,其可以通过直接分化参与组织修复,也可通过旁分泌途径发挥免疫调节、促进创面血管化和再上皮化、动员基底干细胞发挥创面修复作用。

背景:以间充质干细胞为基础的细胞疗法蓬勃发展,在治疗难愈性创面方面具有很大的前景优势。 
目的:综述提高间充质干细胞治疗难愈性创面疗效的策略,以期为临床治疗难愈性创面提供理论依据。
方法:检索万方、CNKI、PubMed、Web of Science 等数据库2002年3月至 2020年3月期间关于间充质干细胞应用于难愈性创面的文献,检索词分别为“间充质干细胞,难愈性创面(慢性难愈性创面),创面修复,组织再生”和“mesenchymal stem cells,nonhealing chronic wound,wound repair,tissue regeneration”。排除陈旧以及重复的观点,将检索到的文献进行整理,共纳入64篇文献来进行分析。
结果与结论:①梳理了难愈性创面的形成机制;②总结了间充质干细胞治疗难愈性创面的分子机制,例如直接分化、旁分泌、免疫调节、动员创面基底干细胞参与创面修复等;③总结了提高间充质干细胞对难愈性创面疗效的策略,例如基因修饰、预处理等;④上述研究为提高间充质干细胞治疗难愈性创面疗效提供了理论依据。

Abstract: BACKGROUND: Mesenchymal stem cell-based therapy is pursued aggressively with promising preclinical studies and higher future prospect in the treatment of nonhealing wounds.
OBJECTIVE: To review the strategies for improving the efficacy of mesenchymal stem cells in the treatment of nonhealing wounds, which are expected to provide theoretical basis for clinical treatment of nonhealing wounds.
METHODS: Wanfang, CNKI, PubMed and Web of Science were searched for articles about the application of mesenchymal stem cells in nonhealing wounds from March 2002 to March 2020. The key words were “mesenchymal stem cells, nonhealing wounds (nonhealing chronic wounds), wound repair, tissue regeneration” in Chinese and “mesenchymal stem cells, nonhealing chronic wound, wound repair, tissue regeneration” in English. After excluding outdated and repetitive viewpoints, the retrieved literature was sorted out and a total of 64 articles were included for analysis. 
RESULTS AND CONCLUSION: (1) The formation mechanism of nonhealing wounds was summarized. (2) The molecular mechanisms of mesenchymal stem cells in the treatment of nonhealing wounds were summarized, such as direct differentiation, paracrine, immunomodulatory, mobilization resident stem cells to participate in wound repair. (3) This paper summarized the improvement of the efficacy of mesenchymal stem cells in the treatment of nonhealing wounds, such as gene modification and pretreatment. (4) This study can provide a theoretical basis for improving the efficacy of mesenchymal stem cells in the treatment of nonhealing wounds. 

Key words: stem cells, mesenchymal stem cells, nonhealing wounds, genetic modifications, preconditioning, wound repair, review
