Hyaluronic acid-methacrylic anhydride/polyhexamethylene biguanide hybrid hydrogel with antibacterial and proangiogenic functions for diabetic wound repair
文献摘要:
Diabetic wounds lead to a decrease in quality of life and an increase in mortality.Current treatment strategies include preventing bacterial adhesion while improving microcirculation.As a new type of wound dressing that imitates natural skin,hydrogel has gradually emerged with its excellent properties.However,existing hydrogels rarely achieve satisfactory results in promoting wound repair and antibacte-rial simultaneously.In this case,we prepared methacrylic anhydride chemically modified hyaluronic acid as a hydrogel matrix,added polyhexamethylene biguanide as an antibacterial component,and loaded sodium alginate/salidroside composite microspheres which could sustainably release salidroside and thus promote angiogenesis.Hybrid hydrogel(HAMA/PHMB-Ms)was synthesized via photocrosslinking,and its chemical structure,particle size distribution and microstructure were characterized.The satisfactory an-tibacterial properties of the HAMA/PHMB(15%)-Ms hydrogel were studied in vitro,and its antibacterial rates against E.coli and S.aureus were 97.85%and 98.56%,respectively.In addition,after demonstrating its good biocompatibility,we verified that the HAMA/PHMB-Ms hydrogel has increased granulation tissue formation,more collagen deposition,more subcutaneous capillary formation,and better wound healing than blank control,HAMA and HAMA/PHMB hydrogel on the back wound model of diabetic mice.The results confirmed that HAMA/PHMB-Ms hydrogel was a promising material for the treatment of the dia-betic wounds.
