摘要:

文题释义:
水凝胶:是一种拥有高含水量且能显著在水中溶胀却又不溶于水的三维网络状交联聚合物,吸水量随交联度的提升而缩减,能够模拟细胞外基质。
皮肤创面修复:是皮肤组织在遭受外力作用损伤后的愈合进程,分为止血、炎症、增殖和成熟4个不同阶段,涉及机体各种调节通路、细胞和分子的分泌释放活动,任何一个阶段受到干扰都可能使创面经久不愈,从而转化为慢性难愈合创面。

背景:水凝胶凭借其三维网络状结构、优越的吸水保湿性和生物相容性在创面修复领域提供了独特的作用。
目的:综述皮肤创面中水凝胶敷料作为支架材料在药物递送与缓释和清创止血方面的应用。
方法:以“水凝胶,创面修复,糖尿病足,皮肤溃疡,烧伤,放射性皮炎,慢性创面,药物载体”或“hydrogels, wound healing,diabetic foot,skin ulcer,burns,radiodermatitis,chronic wounds,drug carriers”为检索词,交叉检索PubMed、CNKI、万方数据库中2000至2019年发表的文献。
结果与结论:水凝胶具有类细胞外基质的三维结构,具有良好的可塑性、保水性和自愈合及持久缓释等特性,作为支架材料负载一种或多种药物应用于皮肤创面能增强各种药物抗感染、止血、清创方面的能力,能促进细胞黏附和生长因子的表达,诱导血管再生、胶原沉积、巨噬细胞极化和肉芽组织形成,最终促进汗腺和毛囊生成,加速上皮化,缩短愈合过程。然而,多功能水凝胶的开发及应用大多处于动物实验的基础研究阶段,尚缺乏大规模临床研究证明其疗效和安全性。

Abstract: BACKGROUND:  Hydrogels play an important role in the field of wound repair because of its three-dimensional network structure, excellent moisture absorption and retention properties and biocompatibility.
OBJECTIVE: To review the application of hydrogel dressings as scaffold materials in sustained drug release, debridement and hemostasis for skin traumas.
METHODS: We took “hydrogels, wound healing, diabetic foot, skin ulcer, burns, radiodermatitis, chronic wounds, drug Carriers” as the key words in Chinese and English, respectively, to retrieve the related literature published from 2000 to 2019 in PubMed, CNKI, and Wanfang databases based on internet search. 
RESULTS AND CONCLUSION: Hydrogels have a three-dimensional structure similar to extracellular matrix and possess good plasticity, moisture retention, self-healing and long-lasting sustained release properties. As scaffold materials, hydrogels loaded with one or more drugs on skin wounds can enhance the anti-infection, hemostatic and debridement ability of drugs, promote cell adhesion and growth factor expression, induce angiogenesis, collagen deposition, macrophage polarization and granulation tissue formation, and finally, lead to the sweat glands and hair follicles formation, epithelialization acceleration, and shorten the healing process. However, the development and application of multi-functional hydrogels are mostly in the basic research stage of animal experiments, and there is still a lack of large-scale clinical studies to prove their efficacy and safety.

Key words: material, hydrogel, self-assembling material, wound repair, diabetic foot, skin ulcer, chronic wounds, drug sustained release, review
