Objective: To study the effect of vacuum sealing drainage combined with biological dressings on the angiogenesis and inflammatory response after diabetic foot ulcer wound grafting. Methods: Patients with diabetic foot who were treated in Sichuan Provincial People’s Hospital between May 2014 and February 2017 were selected and randomly divided into vacuum drainage group and normal control group who received vacuum sealing drainage combined with biological dressings as well as conventional debridement and dressing change to deal with the wound respectively. Before treatment as well as 1 d, 3 d and 5 d after treatment, the wound tissue was collected to determine the expression of angiogenesis molecules, angiogenesis signaling pathway molecules and inflammatory response molecules. Results: 1 d, 3 d and 5 d after treatment, VEGF, VEGFR, CD105, MMP9, PI3K, AKT, cyclinD1, p38MAPK and NF-kB protein expression in wound tissue of vacuum drainage group were significantly higher than those of normal control group while COX-2, iNOS, TNF-α and IL-6 mRNA expression were significantly lower than those of normal control group. Conclusion: Vacuum sealing drainage combined with biological dressings promotes the angiogenesis and inhibits the inflammatory response after diabetic foot ulcer wound grafting.
