Results Compared to those before treatment the volume of the implanted keloid of Group D began to decrease since 14 days after treatment time-dependently (all P 《 0.05), and the volumes of the other 3 groups continued to increase and peaked on days 21, 14, or 7 respectively (all P 《 0.05).Microscopy showed infiltration of a larger quantity of histiocyte in the keloid tissue, and more obvious collagen disorganization and apoptosis of fibroblasts in Group D than in the other 3 groups.The protein expression of Bcl-2 was more remarkable and the protein expression of BAX was less remarkable in Group D than iu the other 3 groups.
