Polyvinylpyrrolidone/chitosan-loaded dihydromyricetin-based nanofiber membrane promotes diabetic wound healing by anti-inflammatory and regulating autophagy-associated protein expression

The healing of wounds in diabetics is commonly delayed by recurring infections and persistent inflammation at the wound site. For this reason, we conducted a study using the electrospinning technique to create nanofiber membranes consisting of polyvinylpyrrolidone/chitosan (PVP/CS) and incorporated dihydromyricetin (DHM) into them. Infrared Fourier transform spectroscopy and scanning electron microscopy were used to analyze the nanofiber membrane. Experimental results in vitro have shown that PVP/CS/DHM has exceptional properties such as hydrophilicity, porosity, water vapor transport rate, antioxidant capacity, and antibacterial activity. Moreover, our study has demonstrated that the application of PVP/CS/DHM can significantly improve wound healing in diabetic mice. After an 18-day treatment period, a remarkable wound closure rate of 88.63 ± 1.37 % was achieved. The in vivo experiments revealed that PVP/CS/DHM can promote diabetic wound healing by suppressing the activation of TLR4/MyD88/NF-κB signaling pathway and enhancing autophagy-related protein as well as CD31 and HIF-1α expression in skin tissues. This study showed that PVP/CS/DHM is a promising wound dressing.
