Therefore, Uighur Medicine syndrome type standards of hyperlipidemia were established. Treatment efficacy was evaluated with the combination of laboratory observation parameters and main and secondary disease manifestations. On this basis, in accordance with the technical requirements of the national medicine review, this study developed clinical research guidelines for the treatment of hyperlipidemia with new Uyghur Medicine (draft).

Objective:To establish a finite element model for bone transport before surgery in the treatment of femoral and tibial bone defects with external fixation and combined intramedullary nails with external fixations, and evaluate the stability and properties of biomechanics.Methods:Between May 2022 and August 2022, a male volunteer in the Department of Trauma and Microreconstructive Surgery, the First Affiliated Hospital of Xinjiang Medical University was selected. The right lower limb was scanned using 64-slice CT. Data were imported into Mimics 21.0 to establish normal geometric models of femur and tibia. The models were arranged in 4 groups: a femoral external fixator group, a femoral external fixator combined with intramedullary nail group, a tibial external fixator group and a tibial external fixator combined with intramedullary nail group. Hypermesh 10.0 was used for meshing. Finite element analysis was performed by Ansys v.11 to measure the distribution and characteristics of equivalent stress in the transported bone segment, proximal and distal tibia, and fixtures in the 2 treatment modalities, respectively.Results:Peak Von Mises equivalent stress of cortical bone and external fixation was found higher in both of the femoral and tibial external fixator combined with intramedullary nail groups than that in the external fixator group, with stress reduction on cortical bone at approximately 76.9% and 77.8%, respectively. The stress reduction on external fixator was about 81.4% and 76.3%, respectively. Peak displacement of the structure in both of the femoral and tibial external fixator combined with intramedullary nail groups was lower than that in the external fixator group, with 78.4% and 60.1% reduction in displacement, respectively.Conclusion:Bone transport with intramedullary nailing combined with external fixator in treatment of femoral and tibial defects would offer better biomechanical advantages. It can facilitates bone regeneration and bone mineralisation during distraction phase and consolidation phase.

Objective:To explore the clinical effect of the modified Quaba flap on reconstruction of the soft tissue defects in distal hand and foot.Methods:From August 2013 to March 2022, 36 cases of soft tissue defect in distal hand and foot were reconstructed by the modified Quaba flap in the Department of Microrepair and Reconstruction of Orthopaedic Centre, the First Affiliated Hospital of Xinjiang Medical University. There were 24 males and 12 females, aged 18 to 58 years old with an average age of 35.6 years old. The sizes of defect were 1.5 cm × 0.5 cm - 5.0 cm × 3.0 cm, including 28 in hand and 8 in foot. Of the defects, 26 were traumatic soft tissue defects, 5 were chronic hand infection and 5 were after resection of hand tumour. The sizes of flap employed were 5.0 cm × 1.5 cm - 10.0 cm × 6.5 cm. Method of optimization included: (1) Extended the paddle of propeller flap or made the rotation point being further; (2) Determined the perforator vessel that entered the pedicle, and made the perforating point as the location of rotation hence to maximise a blood flow; (3) Improved the pedicle mobility and reduced the angle of rotation of the flap; (4) The superficial vein in the pedicle was retained in the modified Quaba flap; (5) Properly retained the fascia tissue of the pedicle; (6) "Skinned-tail" design for the pedicle. All patients entered scheduled follow-up reviews at outpatient clinic and by telephone or WeChat interviews. Colour, texture, wound healing, complications at donor site and hand function were evaluated.Results:All flaps survived. The donor sites were directly closed in 27 patients, and skin grafts were applied in 9 patients. All patients were entered postoperative follow-up for 3-36(mean 24) months. All flaps had good colour and texture but with poor sensation. Wounds healed at the first attention. Hand functions(28 cases) were evaluated according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Hand function appeared excellent in 23 patients, good in 3 and fair in 2, with an excellent and good rate at 92.9%. Motion of all metacarpophalangeal joints were satisfactory. Flexion of metacarpophalangeal joints ranged from 65° to 90°, with an average of 80°. Dorsal extension ranged from 0° to 20° (mean 8°), without obvious joint pain. Foot functions(8 cases) were evaluated according to hallux metatarsophalangeal-interphalangeal scale of the American Orthopaedic Foot and Ankle Society (AOFAS), 6 patients were in excellent and 2 in good.Conclusion:Modified Quaba flap is easy to harvest and with stable and reliable blood circulation. The optimised methods can extend the length of the paddle of the flap and shorten the rotation point. They are very effective methods in reconstruction of the soft tissue defect in distal hand and foot.
