Objective:To explore the clinical application effects of tissue flaps prepared from the discarded limbs after amputation in patients with destructive wounds in the lower limbs.Methods:The study was a retrospective observational study. From March 2019 to March 2024, 7 male patients with destructive wounds in the lower limbs who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of Xiangya Hospital of Central South University, aged 35 to 57 years. After clinical treatment, the damaged limbs were still difficult to preserve. Five patients with destructive wounds in the lower limbs were repaired with pedicled tissue flaps prepared from the discarded limbs after amputation, with wound areas of 15 cm×10 cm to 25 cm×15 cm and tissue flap incision areas of 15 cm×10 cm to 20 cm×15 cm. Two patients with destructive wounds in the lower limbs were repaired with free tissue flaps prepared from the discarded limbs after amputation, with wound areas of 22 cm×18 cm and 25 cm×15 cm and tissue flap incision areas of 23 cm×20 cm and 25 cm×18 cm. The survival of the tissue flap, the healing and appearance of wounds in the recipient site were followed up. At the last follow-up, the recovery status of the recipient site was evaluated according to the comprehensive flap evaluation scale, and the status of corrective prosthesis fitting was recorded.Results:During the follow-up of 6 to 24 months, all the tissue flaps successfully survived, with good healing and appearance of wounds in the recipient site. At the last follow-up, the scores of the recovery status of the recipient site ranged from 36 to 39 (with an average of 37.2). All amputated limbs were able to accommodate corrective prostheses with no distal ulceration.Conclusions:Utilizing tissue flaps prepared from the discarded limbs after amputation in patients with destructive wounds in the lower limbs to repair wounds effectively uses the discarded tissue and avoid creating new donor sites, which is a method to be considered for repairing multiple destructive wounds.

Secondary osteoporosis is common in patients with early breast cancer, manifesting as low back pain, bone and joint symptoms, and osteoporotic fractures. Bisphosphonate and denosumab can reduce the incidence of fractures by minimizing bone loss, though they differ in efficacy, treatment course, and side effects. Patients should consider the pros and cons when selecting a drug. Recent studies also focus on decreasing the incidence of bone metastases. This article reviews recent advancements in the use of these two drugs for managing bone health in early breast cancer.

Objective:To explore the methods and clinical effects of reconstructing facial and cervical scars with expanded flaps based on the "MLT" principle.Methods:The study was a retrospective observational study. From January 2019 to May 2022, 74 patients with facial and cervical scars after burn or trauma injuries who met the inclusion criteria were admitted to Xiangya Hospital of Central South University, including 38 males and 36 females, aged from 5 to 58 years, including 24 patients with simple facial involvement, 24 patients with simple cervical involvement, and 26 patients with both facial and cervical involvement, with scar area ranging from 12 to 145 cm2. By following the "MLT" principle (color and texture similar to the face; flap area large enough to reconstruct the entire defect; skin tissue thin enough to transmit the expression, so as to facilitate the shape of the face and five features); in the stage Ⅰ surgery, the skin and soft tissue expanders (hereinafter referred to as the expanders) were implanted, and in the stage Ⅱ surgery, the expander removal+scar resection+flap transplantation to repair the secondary wound was performed, and the wound in the donor area of flap was directly sutured. After operation, silicone gel preparation and laser therapy were used to prevent scar hyperplasia. The expansion ratio and time period of expanders, the occurrence of complications of skin and soft tissue expansion surgery, the type of flap used, and the survival of flap after the stage Ⅱ surgery were observed and recorded. The long-term effect of facial and cervical reconstruction and the recovery of donor area and recipient area of flap were evaluated during the postoperative follow-up after surgery.Results:The expansion ratio of 135 expanders ranged from 1.36 to 3.00 times, and the expansion time period ranged from 6 to 14 months. During skin and soft tissue expansion surgery, 8 patients had poor healing of incisions after expander placement, 7 patients had expander rupture, 5 patients had infection in incisions after expander placement, 3 patients had expander exposure, 2 patients had difficult filling the injection pot, and 1 patient had water leakage from the injection pot. Dorsal shoulder expanded flaps with double blood supply of transverse cervical artery and circumflex scapular artery were used in 8 patients, the expanded flaps of anterior transverse carotid artery perforator were used in 11 patients, the expanded flaps of internal thoracic artery perforator were used in 12 patients, tandem expanded flaps of upper chest and neck were used in 16 patients, dorsal thoracic artery perforator expanded flaps were used in 5 patients, and adjacent rotary propulsive expanded flaps were used in 22 patients. After the stage Ⅱ surgery, the flaps of 71 patients were completely survived. One patient had blood circulation disorder in the flap, and the flap survived after hyperbaric oxygen treatment. Necrosis occurred at the end of the flaps in 2 patients, which healed after dressing change. After the surgery, 42 patients were followed up for 3 to 24 months. The color, texture, and thickness of flaps were good and similar to the surrounding normal skin tissue in the recipient area, the appearance and function of the face and neck were significantly improved, and the wound location in the donor and recipient areas of flaps was concealed with slight scar formation.Conclusions:In the reconstruction of facial and neck scars, by following the "MLT" principle, the expanded flap was carefully designed before surgery, the local aesthetic features within the subunit are reconstructed during the stage Ⅱ surgery, and standard anti-scar treatment measures are actively adopted after surgery. After reconstruction, the color, texture, and thickness of flaps were close to the normal skin in face and neck, and the appearance and function of face and neck are significantly improved, with less linear scars left. It is beneficial to improve the therapeutic effect.

Objective To evaluate the effect of extracorporeal membrane oxygenation combined with intra-aortic balloon pump mechanical circulatory support for patients with cardiogenic shock complicating acute myocar-dial infarction during PCI process.Methods Patients with cardiogenic shock complicating myocardial infarction who underwent PCI in the hospital from January 2015 to December 2019 were selected.Those who were under support of extracorporeal membrane oxygenation combined with intra-aortic balloon pump were enrolled in the observation group,the patients under support of only intra-aortic balloon pump were selectedin the control group.The differ-ences of clinical features and prognosis were compared.Results A total of 40 patients were enrolled,11 were in the observation group and 29 in the control group.Compared with control group,more patients were complicated with old myocardial infarction(5/11 vs.2/29,P=0.016),more patients were diagnosed as non-ST elevated myocardial infarction(8/11 vs.11/29,P=0.049)and left ventricular ejecting fraction was lower[(38.5±10.10)vs.(48.55±8.86),P=0.01]in observation group.Moreover,the proportion of patients with EF＜35％was higher in the observation group(5/11 vs.3/29,P=0.01).The observation group has significantly higher rates of multi-vessel disease and Syntax scores compared to the control group(multi-vessel disease:10/11 vs.11/29,P=0.02;Syntax score:[(33.36±13.37)vs.(25.74±5.75),P=0.015];the observation group exhibited a higher proportion of patients achieving complete revascularization(9/11 vs.8/29,P=0.002).Mechanical complications were higher in observation group(6/11 vs.5/29,P=0.02),The survive rate in observation group is higher than that in control group(91.00％vs.55.17％,P=0.03)at one-year follow-up.Conclusion Compared with only IABP,ECMO com-bined with IABP hemodynamic support during PCI process for patients with cardiogenic shock complicating acute myocardial infarction enjoys more complete revascularization and better mortality outcome,although it has rela-tively higher mechanical complications.
