Objective To investigate the application and clinical significance of the medial plantar flap on repairing the medial ankle and foot soft tissue defects. Methods A total of 13 patients with the medial ankle and foot soft tissue defects were repaired by the local transferred medial plantar flap alone or in combination with sural neurovascular flap transplantation in the Yuebei People's Hospital Affiliated to the Medical College of the Shantou University from Jun. 2006 to Dec. 2012. Results All patients were followed-up of 4-21 weeks,and the average follow-up periods were 6. 3 weeks. All of the skin and soft tissue defects of the medial ankle and foot were repaired,and there were 2 cases of partial necrosis of flap were repaired after tow times skin grafting operation,and all cases without complications of wound infection or iatrogenic nerve injury. Conclusion The medial plantar flap on treating ipsilateral medial malleolus and foot skin and soft tissue defects is useful and effective with less complications,satisfactory effects,intact the ankle flexor and extensor device,allowing early functional exercise,good functional recovery.

BACKGROUND:Ideal models of spinal cord injury should simulate human spinal cord injury, exclude confounding factors affecting effects, and have extensive repeatability. Spinal cord transection model is an ideal choice at present. Nevertheless, the operation is diverse, so therapeutic effects have great differences, and the research results lack of comparability. OBJECTIVE:To compare and analyze behavioral changes and pathological features of rat hindlimb after spinal cord transection by establishing standardized model of transected spinal cord in rats. METHODS:A total of 60 adult female Sprague-Dawley rats were randomly divided into sham surgery group (n=12), conventional spinal cord transection group (n=24) and microscopic spinal cord transection group (n=24). Each group was randomly assigned to 7-day, 14-day and 28-day groups according to time points after model establishment. T9 vertebrae were considered as a center. Sham surgery group underwent laminectomy. Other groups underwent spinal cord transection. Thus, models of acute spinal cord injury were induced. Models in the conventional spinal cord transection group were established by conventional surgical methods. Models in the microscopic spinal cord transection group were established by standardization micromanipulation technique. At 7, 14 and 28 days after model establishment, motor function of hindlimb was evaluated using Basso, Beattie and Bresnahan (BBB) scoring system. Histopathology of transected spinal cord was observed. The thickness of the glial scar, the longitudinal distance between the two stumps, the transverse diameter of the spinal cord cavity and cerebrospinal fluid cyst formation were measured at the transected site of the spinal cord. RESULTS AND CONCLUSION:In the sham surgery group, preoperative and postoperative BBB scores and pathology of the spinal cord did not clearly change. In the conventional spinal cord transection group and microscopic spinal cord transection group, complete paralysis of hindlimb was detected after model establishment. Hindlimb function did not recover in the conventional spinal cord transection group. At 1 to 2 weeks after model induction, spontaneous recovery of hindlimb function was visible in rats of the microscopic spinal cord transection group. Spinal pathology index value was significantly lower in the microscopic spinal cord transection group than in the conventional spinal cord transection group (P<0.01). Pathological observations were not correlated with BBB scores in each group. These data indicated that standardized spinal cord transection method helps to eliminate individual differences and to quantitatively analyze and to compare studies addressing therapeutic effects.

Objective To investigate the curative effect of scapulohumeral periarthritis treated with arthritis internal injection,manipulation to rehaqe and accessory Chinese herbs extemal lotion treatment combination.Methods From March 1998 to July 2007,332 scapulohumeral periarthritis patients were treated with arthritis internal injection by 1% novocaine (2% lidocaine),triamcindone acetonide,accessory manipulation to release and Chinese herbs external lorion treatment after 3 days.Result All the patients were followed up for 3 months,272 cases(81.9%)were excellent, 59 cases(17.8%)were good,1 case (0.3%)was bad.Conclusions The combination treatment Can relieve the scapulohumeral periarthritis ache and recovery the patient's shoulder function.It has significantly clinical effects.
