摘要
严重机械性创伤以及慢性疾病所导致的皮肤损伤(如糖尿病足溃疡)的愈合过程,常伴随着组织损害、微生物感染、强烈的炎症反应和增生性瘢痕形成等挑战.近年来,微针在促进伤口愈合方面应用广泛.根据作用方式不同,微针制剂分为以下 5类:实心微针、空心微针、包衣微针、可溶性微针和水凝胶微针.本文综述了不同类型微针的制备方法和特点,并总结了其在止血、抑菌、抗炎、胶原蛋白沉积增强和血管新生等关键愈合环节发挥作用的方式,以期为未来的研究与开发提供参考.
Abstract
The healing process of skin wounds caused by severe mechanical trauma and chronic diseases(e.g.,diabetic foot ulcers)is often accompanied by tissue injury,microbial infection,intense inflammatory reactions,hypertrophic scars,and other complications.Microneedles have been widely used to facilitate wound healing in recent years.According to their different modes of action,microneedle formulation can be categorized into five types:solid microneedles,hollow microneedles,coated microneedles,soluble microneedles,and hydrogel microneedles.This paper reviews the preparation methods and characteristics of microneedles,and summarizes their roles in hemostasis,bacteriostasis,anti-inflammation,enhancement of collagen deposition,and angiogenesis,in the hope of providing some reference for future research and development.
