Firstly, this paper analyzed the significance of strengthening medical students’ ecological moral ed-ucation under the view of Beautiful China. Secondly, it discussed the present situation of ecological moral and the reasons of lacking of ecological moral in medical students. At last, the authors pointed out the countermeasures to strengthen the moral cultivation of medical students’ ecological countermeasures under the view of Beautiful China. Therefore, we must strengthen the top-level design to ensure the ecological moral education enter into the national education system, enhance to maintain power to build the full-area coverage ecological moral teaching system, and strengthen institutional construction to establish long-term mechanism of ecologic moral education.

Objective:To evaluate the clinical effect of applying peroneal artery perforator flap with super-draining techniques in repairing skin defects of extremities.Methods:The data of patients with limb wounds admitted to the 990th Hospital of the Joint Logistics Support Force of the People’s Liberation Army from March 2014 to August 2019 were analyzed retrospectively. All were repaired with peroneal artery perforator flaps with super-draining techniques.Cutaneous nerves and perforating vessels were anastomosed according to the routine ratio of 1∶2.The superficial vein and the recipient veinwere matched and marked according to the relative position the diameter and length.Then one to three superficial veins were anastomosed in sequence according to the vein mark number.Upper limb wounds were evaluated by the trial standard of upper limb function evaluation of the Hand Surgery Branch of the Chinese Medical Association.Patients with lower limb wounds were evaluated by the American Orthopaedic Foot and Ankle Surgery Association Ankle-Hindfoot Score System.All patients were evaluated according to the sensory function evaluation standard of the British Medical Research Association.Results:A total of 67 cases were included in this cohort. There were 54 males and 13 females, aged from 21 to 65 years, with an average of 44 years.Eight cases were anastomosed with three superficial veins, 38 cases were anastomosed with two flaps, and 21 cases were anastomosed with one flap.The donor sites were closed directly in 56 cases.Eleven cases received full-thickness skin grafting to cover the donor site.One case showed necrosis of the half flap for the arterial crisis. The wound was repaired by full-thickness skin grafting in further treatment. Three cases had hemorrhage under the free flap, which was healed secondarily after debridement. The remaining were healed well.All patients were followed for 6 to 44 months. There was no obvious swelling and blisters in the early postoperative period.The texture of the flap was the same as the surrounding area.In the later stage, the atrophy and scar were not obvious, without pigmentation. The sensation recovered quickly. The donor site healed without dysfunction.Sixteen patients with upper limb wounds were evaluated by the trial standard of upper limb function evaluation of the Chinese Medical Association Hand Surgery Branch. Twelve cases were excellent, 3 cases were good, and one case was fair. Fifty-one cases of lower limb wounds were evaluated by the American Orthopaedic Foot and Ankle Surgery Association Ankle-Hind Foot Score System. Thirty-eight cases were excellent, 11 cases were good, and two cases were fair. All patients were evaluated according to the sensory function evaluation standard of the British Medical Research Association. The two-point distance discrimination was 8-10 mm, with an average of 9.1 mm. The sensory function of the flaps reached S3+ in 48 cases and S3 in 19 cases.Conclusions:Application of super-draining technique in peroneal artery perforator flap surgery can effectively prevent blood congestion and reduce the necrosis risk of the free flap and complication rate. It can improve the survival quality of the flap and facilitate the recovery of the function of the receiving area.
