Objective:To investigate the feasibility and clinical outcomes of using the deep inferior epigastric perforator flap to repair stage Ⅳ pressure ulcers in elderly patients with the femoral trochanter.Methods:Retrospective analysis of clinical data of elderly patients with stage Ⅳ pressure ulcers of the femoral trochanter treated at the Medical Center of Burn Plastic and Wound Repair, the First Affiliated Hospital of Nanchang University from May 2018 to May 2023 using the deep inferior epigastric perforator flap.The deep inferior epigastric perforator flap was designed on the same side of the abdomen based on the preoperative detection of the paraumbilical perforating branch.The axis of the inferior epigastric artery was determined by the line connecting the femoral artery pulsation point at the inguinal ligament and the obvious paraumbilical perforating branch point. The axis of the skin flap was determined by the line connecting the obvious paraumbilical perforating branch point and the subscapular angle. Combined with the situation of the sinus after pressure ulcer debridement and the range of skin and soft tissue defects, the inferior epigastric artery perforating branch skin flap was cut and repaired. The pedicle of the inferior epigastric artery was freed to the required length according to the location of the pressure ulcer, and the wound was transferred and repaired through a subcutaneous tunnel. The donor area was directly pulled and sutured. The survival of the skin flap and the healing of the donor site wound after surgery were observed, and the recurrence of pressure ulcers, the appearance and texture of the skin flap, and the recovery of the donor site were followed up regularly.Results:A total of 11 patients were included, including 7 males and 4 females; age ranged from 66 to 83 years old, with an average of 72.1 years old. There were total of 11 pressure ulcers in the femoral trochanter, with an area of 5.0 cm × 3.0 cm-13.0 cm ×6.0 cm before debridement and an area of 8.0 cm × 5.0 cm-16.0 cm × 8.0 cm after debridement. The deep inferior epigastric perforator flap was used to repair the wound. The flap was cut with an area of 10.0 cm × 6.0 cm-18.0 cm × 9.0 cm, and the length of the blood vessels in the flap pedicle was 12-16 cm, with an average of 14 cm. After surgery, 9 of the 11 flaps survived completely. One skin flap developed purplish discoloration at the distal end 24 hours after surgery, which was relieved by removing the suture at the site with high tension at the wound edge. One skin flap also showed slight necrosis at the distal end. The flap was removed under local anesthesia at the bedside of the ward, and the surgical wound was directly sutured. After dressing change, it healed. The wounds in the donor area all healed well. Follow up for 3-15 months postoperatively, with an average of 11 months, showed no recurrence of pressure ulcers in all patients. The skin flap had a soft texture, and its color and appearance were similar to those of the surrounding skin. No abdominal wall hernia was observed in the inferior epigastric donor area.Conclusion:The deep inferior epigastric perforator flap has a long vascular pedicle, reliable blood supply, sufficient tissue volume for cutting, no recurrence of pressure ulcers after surgery, good appearance and texture of the affected area, and no secondary abdominal wall hernia in the donor site. It is an effective method for repairing stage Ⅳ pressure ulcers of the femoral trochanter in elderly patients.

Objective:To explore the feasibility and clinical efficacy of reconstruction of the soft tissue defect after keloidectomy and/or cicatricial ulcers excision caused by sternotomy with the 5th intercostal perforator flap of the internal thoracic artery.Methods:From September 2016 to August 2023, 10 patients with sternal keloids and/or sternal scar ulcers caused by sternotomy were treated in the Medical Centre of Burn Plastic Surgery and Wound Repair, the First Affiliated Hospital of Nanchang University. The soft tissue defect after resection reconstructed by the pedicled 5th intercostal perforator flap of the internal thoracic artery. The patients were 7 males and 3 females, aged 17-65 years, with an average age of 43 years. The history of sternal scar was 2-15 years, with an average of 5.5 years. And the sizes of sternal scars were 2.0 cm×6.5 cm-5.5 cm×10.0 cm. After admission, the patients firstly received surgery to remove sternal keloids and/or scar ulcers. The defects of soft tissue were found from 2.5 cm×7.0 cm to 6.0 cm×10.5 cm in size after surgery. Then one-stage reconstructive surgery were performed on all of the patients with a transposition of the pedicled 5th intercostal perforator flap of the internal thoracic artery. Flaps were harvested in surgery at 3.5 cm×7.5 cm-6.0 cm×11.0 cm in size. The donor sites of flaps were pulled and directly sutured. After the surgery, wound healing and flap survival were observed, through regular follow-ups at outpatient clinics, and via internet hospitals or WeChat reviews to monitor the colour and appearance of the flaps, recurrence of keloids and/or ulcers, the appearance of donor sites and the secondary dysfunction of surgery.Results:All incisions healed well after surgery, and all the pedicled 5th intercostal perforator flaps of the internal thoracic artery survived. All 10 patients were included in the postoperative follow-up for a period of 6-31 months, with an average of 15 months. During follow-up, the colour and appearance of the flaps were found good, and the patients were satisfied. There was no recurrence of keloid and/or scar ulcer in the reception sites. Two patients had linear scar hyperplasia at the incision sites over the period of follow-up, due to the failure of adherence to regular scar prevention and treatment after wound healing. Appearances of the donor sites were good without functional impairment.Conclusion:The pedicled 5th intercostal perforator flap of the internal thoracic artery has a better clinical effect in reconstruction of the soft tissue defect after keloidectomy and/or cicatriciad ulcers excision caused by sternotomy and without a postoperative recurrence of a keloid and/or scar ulcer, with a good colour and appearance in the affected area and in a good appearance without a secondary functional impairment at the donor site.

Objective:To explore the clinical effect of a pedicled gracilis musculocutaneous flap on reconstruction of chronic sinus wounds in inguinal region.Methods:From September 2015 to June 2023, 10 patients with chronic inguinal sinus wounds were treated in Medical Centre of Burn Plastic and Wound Repair, the First Affiliated Hospital of Nanchang University. The patients were 6 males and 4 females, aged 15-72 years old with an average age of 45 years old. Causes of injury: 4 patients were of non-healed wound after inguinal lymph node dissection for external genital or penile cancer, 2 of chronic radiation ulcers formed in the inguinal area after radiotherapy, 2 of femoral artery angiography site non-healing after lower limb artery balloon angioplasty, 1 of wound non-healing after resection of inguinal protuberant skin fibrosarcoma, and 1 of non-healing ulceration after repeated scratching due to inguinal pruritus. The wounds were all chronic in the groin region, all with a course over 30 days and sinus formation. Soft tissue defects on the surface of wounds ranged from 2.0 cm × 3.0 cm to 5.0 cm × 7.0 cm, and the depth of the sinus was from 2.0 cm to 5.0 cm. After debridement, ipsilateral gracilis musculocutaneous flaps were taken for defect reconstruction. Size of the flaps was 3.5 cm × 4.0 cm - 8.0 cm × 9.0 cm, the length of the gracilis musculocutaneous composite flaps was 16.0 - 24.0 cm, and the volume of the flap was 96.0 - 180.0 cm 3. The gracilis tissue of the flap was filled into the sinus tract and the wound was covered by the cutaneous tissue of the flap. Donor sites of the flap were pulled together and directly sutured. After surgery, hip movements were avoided and appropriately raised the affected limb, observed the survival of gracilis musculocutaneous flap as well as the healing of donor site. Scheduled postoperative follow-ups were conducted through the visits of outpatient clinic and interviews via WeChat or Internet hospital. Results:All the flaps survived. One flap had bleeding at the edge of flap within 24 hours after surgery and resulted in suture dehiscence. After bedside haemostasis, debridement and re-suture, it was healed. All donor sites achieved primary healing. All of the 10 patients were included in the postoperative follow-up for 6-21 months, with an average of 13 months. The flaps were in good colour and appearance, and the patients were satisfactory with the appearance. Scars were seen in the donor sites, but there was no obvious functional impairment. During the follow-up, no flap rupture occurred.Conclusion:The pedicled gracilis musculocutaneous flap is used to reconstruction of chronic inguinal sinus wounds, which can fully fill the sinus tract and simultaneously reconstruct the soft tissue defect of wound. This surgery is simple, practical and with good clinical efficacy.

Objective: To analyze dietary pattern and its seasonal characteristic in residents of Shanghai. Methods: A representative sample was surveyed and followed up in four different seasons during 2012-2014. Information of food consumption was collected by 3-day 24-hour dietary recall and condiments weighing method. The intake of energy and macronutrients were calculated according to the Chinese Food Composition Table. Results: Annual average daily intake was 191.09 g for grain, 250.69 g for vegetable, 107.23 g for fruit, 223.53 g for animal food, 96.39 g for dairy products, 11.19 g for soy bean and its product, 36.54 g for cooking oil, and 7.57 g for salt. Significant differences were observed in food consumption among different seasons (P<0.05). Annual average daily intake of energy was 2 048.70 kcal, carbohydrates was 241.04 g, protein was 82.35 g, fat was 85.99 g and proportion of energy contributed by fat was 37.99%. Different seasons, age, residential areas, and income were influence factors for food consumption (P<0.05). Conclusions: Energy intake was adequate in residents of Shanghai. Unhealthy dietary pattern, including high proportion of fat and consumption of cooking oil and salt (lower than average intake of large cities, but higher than recommendation), was observed. It is necessary to take appropriate nutrition intervention, and future researches on dietary intake should consider seasonal influences.
