Polyvinyl alcohol (PVA), sodium alginate (Alg) were adopted as building blocks to form BNH. Calcium ions was used as crosslink agent to construct BNH. The skin injury model of diabetic rats was successfully established, and the prepared hydrogel was applied to the wound. Animal experiments proved that BNH could promote wound healing of diabetic rats. Further molecular mechanism research revealed that BNH could inhibit the expression of NF-κB, TNF-a and IL-6, but increase the expression of F VEGF, CD 31 and SMA by activating Sirt 1 which were benefit for wound healing of diabetic rats.Graphical abstract
