Liposomal gel loaded with pro-xylane intermediate promotes chronic wound healing

Chronic wounds are a common and difficult problem in clinics. It is of great significance to develop effective and economical methods to treat chronic wounds. The present study aimed to investigate the effects of liposomal gel loaded with Pro-xylane intermediate on chronic wounds. Rat models of chronic wounds were created and verified. The pro-xylane intermediate (C-β-D-xylopyranoside-n-propan-2-one, PXYI) were encapsulated with liposomes and the liposomes containing PXYI were mixed with Pluronic F-127 gel to obtain PXYI liposomal gel (PXYI-LG). PXYI-LG has been applied to the rat's chronic wounds. The therapeutic effects were evaluated by wound healing rate and wound healing time. Additionally, Alamar Blue was used to detect the effect of PXYI on the proliferation of human skin fibroblasts (HF) and human immortalized epidermal cells (HaCaT). It was not found that PXYI alone could promote the proliferation of HF and HaCaT. From the 12^th to the 32^nd day, the wound healing rate of PXYI-LG group were significantly higher than that of the normal saline (NS) group (P <0.05). The number of days when the wound healing rate reached 90% was significantly shorter in the PXYI-LG group (21.8 ±1.8) than in the NS group (28.4 ±1.6) (P < 0.01). In summary, the results demonstrate that the PXYI-LG can promote chronic wound healing.
