[Objective]To inrestigate the clinical outcomes of using bilateral tibial flap of the second toe nail flap combined with the fibulal flap of the big toe to repair the multi-finger degloving injury.[Method]A variety of different methods were used to repair the multi-finger degloving injury,six fingers in 3 cases were repaired by partial bilateral wrap-around flaps combined with the tibial flap of the second toe.Sixteen fingers in 8 cases were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe.Six fingers in 2 cases were repaired by bilateral second toenail flap,the fibulal flap of the big toe and the digital arterial island flap.Three fingers in l case were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe and the the lateral flap of dorsum of foot.Six fingers in 3 cases were repaired by bilateral second toe nail flap and the fibulal flap of the big toe and bilateral dorsum flap of foot.Four fingers in 1 case were repaired by partial bilateral wrap-around flaps and the tibial flap of the second toe and the anterolateral thigh flap.Six fingers in 3 cases were repaired by bilateral second toe nail flap combined with the fibulal flap of the big toe,and bilateral dorsum flap of foot and bilateral anterolateral thigh flap.[Result]Ninety-seven flaps of 98 flaps of 47 fingers in 21 cases were suvived well,with 1 flap developed necrosis.The follow-up duration ranged from 6 months to 9 years in 17 cases (37 fingers).In addition to the activities of DIP limited,the other interphalangeal joint activities were nearly normal.All of the fingernail grew well.Two point discrimination of the fingers was between 5mm and 11 mm.The donor site was hardly affected.[Conclusion]It is a better method using the big toe flap combined with the second toe flap to repair the the multi-finger degloving injury at one stage.

Objective To investigate the protective effect of adiponectin on angiotesin Ⅱ (Ang Ⅱ)-mediated cardiomyocyte apoptosis,and explore the related mechanism. Methods Cardiomyocytes isolated from neonatal rats were cultured in vitro. The identity of cardiomyocytes was confirmed by morphological examination and staining with anti-sarcomeric ?-actin antibody,and most (more than 95%) of the cells were identified as neonatal rat ventricular myocytes. After being placed in a serum-free medium for 24 hours,the ventricular myocytes were randomly grouped and received the following treatments respectively:placebo,or Ang Ⅱ (1?mol/L),or Ang Ⅱ (1?mmol/L) plus adiponectin (30mg/L). The protein levels of Bcl-2 and Bax were detected by Western blotting. The apoptotic rate and the levels of intracellular reactive oxygen species (ROS) in the ventricular myocytes were determined by flow cytometry. The survival rate of ventricular myocytes was evaluated by trypan blue staining. Results As compared with placebo group,the apoptosis of neonatal rat ventricular myocytes was significantly promoted in 1?mol/L angiotesin Ⅱ group,the survival rate of cardiomyocytes was significantly reduced,with the protein expression of Bax and the ROS level increased,and the protein expression of Bcl-2 decreased (P

Objective To investigate the clinical efficiency of repairing ankle and calf wounds by antegrade or retrograde perforating flap of posterior tibial artery. Methods 13 cases with skin defects of ankle and calf wounds were reviewd. The defects were repaired using antegrade or retrograde perforating flap of posterior tibial artery from January 2011 to February 2013, 8 males and 5 females; aged 19 to 65 years old. Wounds were located in the ankle and calf, area which the tibial artery support contu-sioned slightly;defects were associated with exposed bone or tendon, exposed blood vessels. Of the 13 cases, 5 cases have multiple ankle fracture with blood circulation disorders, internal and external fracture fixation were performed emergency with blood ves-sels and nerves exposed, at the same time emergency line wound repair by posterior tibial artery perforating flap. The other 8 cases have no blood vessels and nerves exposure, and accepted vacuum sealing drainage emergency external fixation and flap surgery. Seven cases accepted V-Y antegrade perforating flap of posterior tibial artery, 6 cases using retrograde tibial artery perforator flap. Whose defects were ranged from 1.5 cm×2.0 cm to 9.0 cm×5.0 cm. Antegrade or retrograde perforating flap of posterior tibial ar-tery with 1.5 cm×3.0 cm to 14.0 cm×7.0 cm was used to repair ankle or lower leg medial defect. Antegrade flap donor site sutured directly, but retrograde flap donor site take full thickness skin graft repair from abdomen. Results Circulations of the all 13 cases were stable, with wound healing well after 2 weeks. The patients were followed up for 6 months to 24 months, average of 13 months. All flap graft survived, pedicle no bloated andcat eardeformity. Flaps were soft, no bloated appearance;color was con-sistent with normal skin. Fracture line in the 5 patients was disappeared. Bone healing time was 3.0 to 4.0 months. At the direct su-ture skin donor sites, postoperative scar was small;skin graft donor sites had no obvious scar. Postoperative ankle dorsiflexion 10° to 25°, plantar flexion 15° to 45°. Patients were extremely satisfied with the results of repair. Conclusion Using antegrade or ret-rograde posterior tibial artery perforator flap without sacrificing the main vessel, it is a simple and effective method to repair the medial malleolus and calf wounds.

Objective To explore the method for repair of total avulsion of 2~4 fingers and to find the best procedure. Methods The wrap-round flap with part toenail combind with the dorsal pedical flap to repair soft tissue defect of the dorsal of finger and part of the palmar of finger, the second simepulp flap to repair soft tissue defect of the palmar of finger,transfer of two tissues with one pedicle to repair total avulsion of 2~4 fingers. Results All of 9 composite transplants in 6 cases were survived,the received areas were primary healing in 8 finger,1 case repaired by the bilateral wrap-round flaps and second simepulp flaps for index and middle finger,the distal phalanx of middle finger necrosis because of dislocation of DIP,3 months later,injury healed after the necrosis of phalanx excised,but the nail and the nail bed were dead.Except 1 case which the grafted skin necrotized in the donor area of the big toe,the rest had primary healing.All cases were followed up 6~14 months,the activity of joints were: MP 0-70,PIP 0-40.The repaired pulps had excellent appearance,the nail was fine,1 finger's mail was atrophy and 1 finger's nail was defect.The donor area had good fountion without pain and edema,the grafted skin had normal color and the activity of joints were nomal. Conclusion The wrap-round flap with part toenail combined with the second simepulp flap is a good approach in treatment of the skin avulsion injury in the finger.

Objective To investigate the clinical effects,feasibility,points for attention and complications of treating distal radial fractures through minimally invasive palmar locking plate.Methods A total of 22 patients with distal radial fractures managed by minimally invasive palmar locking plate from August 2009 to August 2010 were enrolled in the study.According to AO classification,there were five patients with type A2 fractures,three with type A3,four with type B1,seven with type B3,two with type C1 and one with type C2.Two vertical or parallel palmar incisions of 2 cm long were performed.The distal transverse incision was along the proximal wrist crease,while the distal and proximal vertical incisions were close to the radial side of flexor carpi radialis.Then,palmar locking plate was inserted through deep pronator quadratus.Results Follow-up period was 10-18 months(mean,12 months).According to Dienst function evaluation criteria,the results were excellent in 13 patients,good in six,fair in three and poor in zero,with excellence rate of 86%.Complications were as follows:one patient had delayed healing of proximal wrist crease incision;one patient had numbness of thenar eminence and the symptom was disappeared three months postoperatively;two patients remained pain on ulnar side of the wrist joint;two patients had limited function of the wrist joint.Conclusions Minimally invasive palmar locking plate is safe,mini-invasive and reliable when treating distal radial fractures,which is conducive to early functional exercise.Furthermore,the method achieves satisfactory appearance of the incision which meets the minimal invasion and thus deserves clinical practice.
