Objective  To investigate the effect of hydrochloric propranolol cream and its possible mechanism on wound healing in diabetic mice. Methods  Eighteen 8-week-old BKS.Cg-Dock7m+/+Leprdb/JNju diabetic mice were randomly divided into control group (n=9) and experimental group (n=9). After full-thickness dermal wounds (0.6 cm in diameter) was made, wounds were treated with cream containing hydrochloric propranolol (experimental group) or not containing hydrochloric propranolol (control group) at 2, 5, 7, 10, 14, and 17 days. At 2, 5, 7, 10, 14, 17, and 21 days, wound healing was observed, and healing rate was calculated; HE staining, Masson staining, and toluidine blue staining were used to observe wound re-epithelialization, collagen fibers, and mast cells distribution. Western blot was applied to detect the expressions of interleukin 1β (IL-1β) and angiogenin 2 (Ang2) in wound tissue. Results  Wounds healed in 2 groups, but the wounds healing rate of experimental group was significantly higher than that of control group at other time points (P < 0.05) except 21 days (P > 0.05). The histological observation showed that re-epithelialization rate was higher in experimental group than control group, there were less mast cells in the wound. The experimental group was lower than control group in IL-1β expression at 2, 5, 7, 14, 17, and 21 days and in Ang2 expression at 2, 5, 7, 10, 14, 17, and 21 days. Conclusion  Hydrochloric propranolol cream can promote wound healing in diabetic mice, which potential mechanism is that propranolol can promote epidermal cell proliferation, reduce inflammation, and benefit angiogenesis.
