Objective:To explore the clinical effect of using great toe fibular flaps of both feet on reconstruction of pulp defects of two neighbouring digits.Methods:A total of 14 digit pulp defects in 7 cases were repaired in Zhoukou Huaihai Hospital using great toe fibular flaps of both feet from August 2020 to January 2023. Of the 7 cases, there were 4 males and 3 females, with an average of 28 years old, ranging from 19 to 45 years old. Meanwhile, there were 4 cases in left hand and 3 cases in right hand. There were 3 cases of digit pulp defects in index and middle fingers, 2 in middle and ring fingers, and 2 in thumb and index fingers. The area of soft tissue defect in 1.2 cm×1.5 cm-3.0 cm×2.5 cm, and flap was 1.5 cm ×1.8 cm-3.2 cm×2.8 cm. Furthermore, 1 case underwent emergency surgery and 5 were repaired in elective surgery. The donor site of the flap was closed directly, and an intermediate-thickness skin graft was prepared from the medial plantar area for transfer in the case of high suture tension at the wound edge. After surgery, patients received postoperative by outpatient clinic and WeChat to observe the appearance, sensation, functional recovery and flap contracture of digits, as well as the movement of the great toes of both feet.Results:After the surgery, all flaps in the 7 cases survived smoothly and the donor sites healed. All patients entered scheduled follow-ups postoperatively for 6 months to 2 years, with an average of 9 months. The flap showed an aesthetic appearance and excellent sensation, with a TPD of 3-6 mm, and satisfactory digit function. The donor site of the great toe fibular flap left linear scars only, without abnormality in range of motion and gait in walking. In addition, there were 5 in excellent and 2 in good according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Conclusion:Application of great toe fibular flaps of both feet is an ideal option for the simultaneous repair of pulp defects of two neighbouring digits, which can achieve good reconstructive results.

Objective To investigate the application of artificial intelligence-based follow-up plan for patients after percutaneous coronary intervention(PCI).Methods The follow-up plan of artificial intelligence after PCI was constructed through literature review and expert correspondence consultation.A total of 82 patients with coronary heart disease who underwent PCI in the Second Affiliated Hospital of Nanchang University from October 2022 to November 2023 were selected and divided into intervention group and control group according to random number table method,with 41 cases in each group.The control group was given routine nursing program,and the intervention group was added artificial intelligence-based follow-up program on the basis of control group.The incidence of major adverse cardiovascular event(MACE)within 6 months,30 days readmission rate,medication compliance and satisfaction score were compared between two groups.Results The incidence of MACE within 6 months and 30 days readmission rate in intervention group were significantly lower than those in control group(P＜0.05).After 6 months of intervention,Morisky scale score and satisfaction score of patients in two groups were significantly higher than before intervention(P＜0.05),and Morisky scale score and satisfaction score of patients in intervention group were significantly higher than those in control group(P＜0.05).Conclusion Follow-up program based on artificial intelligence technology can reduce the incidence of MACE and 30 days readmission rate of patients after PCI.

Objective:To explore the clinical efficacy of free superficial circumflex iliac artery perforator flap (SCIAPF) in reconstruction of soft tissue defects of hand and foot in children.Methods:From August 2021 to August 2023, free SCIAPFs were used to reconstruct soft tissue defects of hands and feet in 8 children at the Department of Hand and Foot Surgery, Zhoukou Huaihai Hospital. There were 6 boys and 2 girls aged between 2 and 7 years old. The sites of soft tissue defect were: 1 of metacarpophalangeal joint in the functional area of left thumb, 2 of dorsal right hand, 1 of dorsal left foot, 2 of medial malleolus of right foot, and 2 of right forefoot, and all were accompanied with tendon and bone exposure. The size of soft tissue defects ranged from 2.5 cm×3.0 cm to 6.0 cm×3.5 cm. After emergency debridement, the children received flap transfers, the flaps sized from 3.0 cm×3.5 cm to 7.0 cm×4.0 cm. Donor sites were closed by running intradermal suture. All children were included in the scheduled postoperative follow-up by visit of outpatient clinic, WeChat interviews and home visits to observe the appearance, colour, texture and sensation of the flaps, the functional recovery of the affected hands and feet, as well as the healing of donor sites.Results:After surgery, all 8 flaps survived beside 1 had a partial necrosis at the edge and healed with a scab after dressing change. Flap donor sites healed in one stage. Scheduled postoperative follow-up lasted from 7 to 22 months, with an average of 10 months. The flaps presented a slightly bloated appearance, soft texture with a restored protective sensation and satisfactory functional recovery of hands and feet. Linear scars were left at the donor sites. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 1 child was of excellent and 2 children of good in hand function of the 3 children with hand injury. The Maryland Foot Score revealed 3 children were of excellent and 2 of good in foot function of the 5 children with foot injury.Conclusion:Free SCIAPF is an ideal option for reconstruction of soft tissue defects of hand and foot in children, with concealed donor site, convenient flap harvesting, fewer complications and satisfactory reconstructive effect.
