"Simmer pus and grow flesh" method promotes chronic wound healing in rats via bFGF-Wnt β-catenin signaling pathway

Enhancing wound healing via bFGF and Wnt pathways

Abstract

The purpose of this study was to explore the mechanism of "simmer pus and grow meat" method based on bFGF regulating WNT / β-Catenin signaling pathway. Of 100 SPF rats, 25 were randomly selected as blank group, and 75 rats were established chronic infectious wound model and divided into blank group, model group (normal saline treatment, n = 25), experimental group (purple and white ointment treatment, n = 25), and wet burn ointment group (wet burn treatment, n = 25). The wound healing rate of rats was compared. The protein expressions of PCAN, VEGF, bFGF, β-Catenin, GSK-3β and C-Myc in granulation tissues were detected. On the 7th day, the wound healing rate of the model group was lower than that of the other 3 groups (P<0.05), and the wound healing rate of the positive control group was higher than that of the experimental group and the control group (P<0.05). The expressions of bFGF, GSK-3β and C-MyC in model group were higher than those in control group (P<0.05). The β-catenin protein expression in the model group was lower than that in the control group (P<0.05), and the β-catenin protein expression in the experimental group and the positive control group was higher than that in the model group (P<0.05). The expressions of PCAN and VEGF in model group were lower than those in model group (P<0.05). We found that Zibai ointment promotes chronic wound healing by modulating the bFGF/Wnt/β-Catenin signaling pathway.
