[Objective]To compare curative effects of radial head resection with internal fixation in treatment of Mason type-Ⅱ、Ⅲ fracture of radial head.[Method]Forty-five patients with Mason type-Ⅱ、Ⅲ fracture of radial head were dividered into 2 groups(A and B).The patients in group A(n=23) were performed with radial head resection.The patients in group B(n=22) were performed with open reduction and internal fixation.The results of the two groups were assessed for statistical analysis on the following aspects: pain,motion,strength and X-ray finding.Broberg and Morrey criterion were used to compared curative effect of elbow function between the two groups.[Result]The patients in the two groups were followed up for a mean time of 8 years(group A) or 3 years(group B).The difference of the pain VAS score,mean flexion/extension of the elbow,Broberg and Morrey elbow scores,carrying angle and shift of radius between the two groups were with statistical significance(P0.05).[Conclusion]In comparing with the radial head resection,open reduction and internal fixation can obtain more satisfactory elbow motion,greater muscle strength and better joint function m the treatment of Mason type-Ⅱ、Ⅲ fracture of radial head.

Objective: To explore the relation of the serum level of sIL-2R in relapse patients with acute lymphoblastic leukemia(ALL). Methods:With ELISA, we determined the levels of sIL-2R of 48 patients with ALL after their first diagnoses,complete remission 1 and relapse. The levels of sIL-2R of 30 patients from complete remission 1 to relapse were monitored. Results: The levels of sIL-2R were higher in the relapse group and first diagnosed group than in the control. The levels of sIL-2R were higher in the relapse group and first diagnosed group than in the complete remission 1 group. However,the difference between the complete remission 1 and the control had no statistical significance. When we determined the levels of sIL-2R dynamically, we found that after complete remission ,the levels of sIL-2R decreased,however, before one month of hematological relapse, the levels of sIL-2R increased. Conclusion: Monitor of the level of sIL-2R can predict impending relapse of patients with ALL and is helpful to early diagnosis of relapse.
