ABSTRACT
Objective To use ReCell technique for the treatment of vitiligo in stable period,and to observe the clinical effect of double side planting of silk protein biological dressing.Methods From July 2015 to July 2017,21 patients with vitiligo in the Department of Dermatology,PLA Air Force Medical Center were selected.The epidermis cell suspension was made from the autologous skin blister wall by the ReCell technology,which was implanted on the transplant wound and silk protein biological dressing surface of vitiligo patients.Results In 21 patients with vitiligo,the skin wounds healed in 7-10 days after transplantation,and all of them had different degrees of color restoration.One month after transplantation,the transplantation site turned red with slight pigmentation,and the border disappeared.After 1,3 and 6 months of transplantation,the recolor rates were 81.82％,87.87％ and 93.35％,respectively.After 6 months of transplantation,the rate of 3-4 grade color restoration was 87.09％.The pigment recovered stably and the color was close to the normal skin,and no adverse reactions such as scar were found.Conclusions ReCell technology,the method of double side planting on vitiligo transplant wound and silk protein biological dressing is effective and worthy of clinical application.
