摘要
背景:活性微生态水凝胶是创面敷料研究领域的一大热点,受到广泛关注。目的:概述活性微生态水凝胶的基本特点与优势,综述近年来各种活性微生态水凝胶在皮肤创面修复中的应用进展。方法:以“cell,probiotics,phage,chlorella,algae,living microecological,hydrogel,skin,wound healing,wound repair”为英文检索词,以“细胞,益生菌,噬菌体,小球藻,微藻,活性微生态,水凝胶,皮肤,伤口愈合,伤口修复”为中文检索词,在Web of Science、PubMed、中国知网及万方数据库进行文献检索,文献检索时限为各数据库建库至2024年。按照排除和纳入标准筛选纳入文献,最终纳入108篇文献进行综述。结果与结论:活性微生态水凝胶具有良好的生物相容性,能为负载的生物提供适宜的生存环境,并在活性生物与皮肤创面之间发挥屏障作用,避免潜在威胁。相较于传统伤口敷料,活性微生态水凝胶的作用是可持续可更新的,生物调节能使创面处微环境保持相对稳定的状态,可以长时间为创面愈合提供适宜条件,减少频繁更换敷料给皮肤创面造成的额外创伤。相较于直接使用活性生物促进皮肤创面愈合,活性微生态水凝胶能提高生物的存活率,保障其发挥生物调节作用。活性微生态水凝胶主要是通过调控创面愈合进程中“炎症”和“增殖”这两阶段来促进皮肤创面愈合。现有的活性微生态水凝胶主要负载细胞、益生菌、微藻、噬菌体这几类生物,赋予了水凝胶不同的生物特性,使其通过释放创面愈合所需物质或者改善创面环境等促进皮肤创面愈合,具有较大的应用潜力。为进一步扩大活性微生态水凝胶的实际临床运用,未来还需要进一步深入把控水凝胶中活性生物的生物安全风险,避免潜在的生物威胁,并需要研究更能适应人体皮肤创面复杂变化且能负载活性生物的水凝胶基质。
