Research Progress of Hydrogels in Diabetic Ulcer Repair
Diabetes foot ulcer(DFU)has become one of the main complications of diabetes.DFU,with its characteristics of high local sugar,susceptibility to infection,and easy spread of ulcers,can cause ulcers to persist for a long time.The traditional medical dressings used for DFU treatment have a single function and cannot achieve good results.Hydrogel dressing is a kind of extremely hydrophilic three-dimensional network structure gel,which has good biocompatibility and can be well integrated with drugs.It is an ideal drug carrier,and also a hot spot of material research at home and abroad in recent years.It shows great potential in the treatment of DFU.This article reviews the pathogenesis of DFU,the structural design of hydrogel dressings,delivery strategies and applications,which can provide new ideas for the treatment of DFU.
