Abstract:
Objective:To observe the therapeutic effect of medical maggot on diabetic foot, and analyze its possible mechanism.Methods:Sixty diabetic foot ulcer patients with Wagner grade 1 or 2 from July 2018 to September 2019 in Second Affiliated Hospital of Dalian Medical University were selected. The patients were divided into control group and experimental group by random digits table methods with 30 cases in each group. The control group was treated with traditional method, and the experimental group was treated with medical maggots. In experimental group, the wound surface Notch 1 mRNA expression before treatment and at the 4th day of treatment was detected by polymerase chain reaction method. The recovery rate 21 d after treatment was compared between 2 groups.Results:The recovery rate in experimental group was significantly higher than that in control group: 100.00% (30/30) vs. 76.67% (23/30), and there was statistical difference ( χ2 = 7.925, P<0.01). In experimental group, there was no statistical difference in the wound surface Notch 1 mRNA expression between before treatment and the 4th day of treatment (0.96 ± 0.08 vs. 0.93 ± 0.08; t = 1.545, P>0.05). Conclusions:Medical maggot has an obvious effect on Wagner grade 1 or 2 diabetic foot ulcers, but its mechanism maybe unrelated to Notch1 signaling pathway.
