摘要:

背景:慢性创面也称难愈性创面,可严重影响患者的生存质量并增加患者经济及社会医疗资源负担。细胞治疗作为一种新的创面治疗方法,在慢性创面的修复中已日益受到重视。
目的:对目前慢性创面的愈合机制及细胞治疗的研究进展做一综述,旨在为临床慢性创面治疗及开展相关研究提供参考。
方法:分别以“难愈性创面、糖尿病足、创面愈合、细胞治疗”和“non-healing wounds、diabetic foot ulcer、wound healing、cell therapy”为关键词进行检索,CNKI数据库的检索时限为2005至2012年,PubMed数据库的检索时限为1995至2012年,西文生物医学期刊文献数据的检索时限为2000至2012年,检索内容为慢性创面的难愈机制以及细胞治疗在慢性创面愈合中的应用。保留符合纳入标准的42篇文献进行总结分析。
结果与结论:创面愈合是多种细胞、细胞外基质及细胞因子等共同参与并高度协调、调控的复杂生物学过程。而难愈创面的愈合延迟严重影响患者的生活质量并增加了经济负担。目前有很多方法用于创面修复,如局部高压氧治疗、外科手术处理、各种生长因子、中药、细胞治疗等,其中细胞治疗由于几乎没有创伤、可通过投递到创面的细胞分泌创伤修复所需的生长因子、细胞因子并通过信号传导而参与到创伤修复全过程、发挥接近正常修复功能而备受人们关注。目前用于治疗慢性创面的细胞主要有骨髓干细胞、骨髓间充质干细胞、脐血干细胞、外周血干细胞、表皮干细胞、皮肤源祖细胞、脂肪干细胞、成纤维细胞、血小板等。

Abstract:

BACKGROUND: The chronic wounds, also called non-heading wounds, can seriously affect the quality of life of patients and has brought heavy burden to patients, as well as health care professionals. Cell therapy is a new method for promoting wound healing and plays an important role in the repair of chronic wounds.
OBJECTIVE: To summarize the progress of researches on the chronic wound healing mechanism and cell therapy, and to provide evidences for the clinical management of chronic wounds and relative basic researches.
METHODS: A computer search of CNKI database from 2005 to 2012, PubMed database from 1995 to 2012 and Foreign Medical Journal Full-Text Service database from 2000 to 2012 was performed using “non-healing wounds, diabetic foot ulcer, wound healing, cell therapy” in Chinese and English as the key words to retrieve articles about chronic wound healing mechanism and the application of cell therapy. Totally, 42 articles meeting the inclusive criteria were included in result analysis。
RESULTS AND CONCLUSION: The wound healing is a complex biological process, involving multiple cell types, extracellular matrix and cytokine factors. The delayed healing of refractory wound seriously affects the quality of life of patients and has brought heavy economic burden to patients. At present, many methods have been employed to promote wound repair, such as local hyperbaric oxygen therapy, surgical treatment, herbal Chinese medicine, application of various growth factors, cell therapy and gene therapy. Cell therapy is noninvasive and those delivered cells can adapt to their environment, are able to release growth factors and cytokines, and more importantly, are able to deliver the growth factors for the wound healing process due to cell signaling capabilities. Currently, cells used for the treatment of chronic wound cells mainly include bone marrow stem cells, bone marrow-derived mesenchymal stem cells, cord blood stem cells, peripheral blood stem cells, epidermal stem cells, skin-derived progenitor cells, adipose stem cells, fibroblasts and platelets.
