Abstract:
Objective To observe the therapeutic effect and mechanism of external application with Shilian Powder combined with oral administration of Shumai Capsules for the treatment of rats with diabetic foot ulcer(DFU).Methods Eight male rats with successfully modeled foot ulcer(DF)were used as the control group.While 24 male rats with successfully modeled DFU were randomly divided into DFU group,Shumai Capsules group and Shilian Powder combined with Shumai Capsules group,with eight rats in each group.After the corresponding interventions,we determined the wound healing rate,histopathological changes of wound,levels of inflammatory factors such as interleukin(IL)-6,IL-1β and vascular endothelial growth factor(VEGF)in serum,levels of Apelin and Relaxin,and protein expressions of phosphatidylinositol 3-kinase(PI3K),protein kinase B(AKT)and VEGF in wound tissue,as well as mRNA expressions of PI3K,AKT,Relaxin and Apelin.Results Compared with the control group,the DFU group showed a significant decrease in wound healing rate,VEGF level in serum and wound,wound Relaxin level,protein and mRNA levels of wound AKT(P<0.05),and a significant increase in serum IL-6 and IL-1β levels,wound Apelin level,wound PI3K protein and mRNA levels(P<0.05),and the reduced wound granulation tissue and formation of new capillaries and increased inflammatory cell infiltration were seen under the microscope.Compared with the DFU group,the wound healing rate,VEGF level in serum and wound,wound Relaxin and Apelin levels,protein and mRNA levels of wound PI3K and AKT in the Shumai Capsules group and Shilian Powder combined with Shumai Capsules group were significantly increased(P<0.05),and serum IL-6 and IL-1β levels were significantly decreased(P<0.05),and the increased wound granulation tissue and formation of new capillaries and reduced inflammatory cell infiltration were seen under the microscope.Compared with the Shumai Capsules group,the wound healing rate,wound VEGF level,wound Relaxin and Apelin levels,protein and mRNA levels of wound PI3K and AKT in Shilian Powder combined with Shumai Capsules group were significantly increased(P<0.05),and the serum IL-6 and IL-1β levels were significantly decreased(P<0.05),and the increased wound granulation tissue and formation of new capillaries and reduced inflammatory cell infiltration were seen under the microscope.Conclusion External application with Shilian Powder combined with oral administration of Shumai Capsules can promote the wound healing in rats with DFU,its mechanism is related to the activation of PI3K/AKT/Relaxin/Apelin signaling pathway.
