[Objective]To study the application and clinical results of the adjustable erternal fixation of ankle joint(AEFA) in orthopedic surgery.[Method]From January 1999 to May 2005,45 cases(55 feet)of equinovarus deformity were treated with orthopedic surgery.In order to preventent the deformity relapsion,the patients were assigned to two groups.The A group(26 cases,32 feet)patients were treated with the adjustable erternal fixation of ankle joint(AEFA).The B group(19 cases,23 feet)patients were treated with plaster immobilization.The orthopedic surgery effect and functions of ankle joint were studied and tested with independent sample t test and x~2 test.[Result]Thirty-eight cases were fellowed-up for 3 months to 9 years(averaged 19 months).There were significant difference between the two groups in the functions of ankle joint.[Conclusion]The new apparatus can effectively prevent the foot-drop deformity and enhance the function of ankle joint.

Objective To observe the interference actien of Buqi Huoxue Decoction(Herbal decoction for reinforcing qi and activating blood)on the model rats with acute cerebral ischemia.Methods Sixty SD rats were randomized into 6 groups,i.e.sham operation group,model group,nimodipine group,and Buqi Huoxue Decoction groups of high,middle,and low dosages,with 10 rats in each.Except the model and sham operation groups,the others were given Buqi Huoxue Decoction through intragastric gavage for 5 days.The acute cerebral ischemia models were made on the sixth day.One hour before modeling,the last medication was applied.At the time point 6h,12h,and 24h,the blood sample was taken from the aorta abdominalis for detecting the tumor necrosis factor-?(TNF-?).After 24h,the hemorheology test was performed.Results Compared with the model group,the whole blood viscosity including the high shear rate and low shear rate and erythrocyte aggregation index of the Nimodipine group and Buqi Huoxue Decoction groups of high and middle dosages were lowered(P
