CT运动成像评判类风湿性关节炎患者关节运动能力并探究其与类风湿因子的相关性

A Study of the Evaluation of the Joint Movement Ability of the Patients with Rheumatoid Arthritis by CT Imaging and Explore its Correlation with Rheumatoid Factor

目的应用320CT的运动成像功能来评判类风湿关节炎受试者的关节运动及其与类风湿因子的相关性。方法选择类风湿性关节炎且累及其双侧腕关节者20例,应用320层动态CT运动成像研究其腕关节,检测尺侧的偏转度、桡侧的偏转度、尺桡侧的活动度以及血清中类风湿因子的水平。结果受试者双侧腕关节的尺侧角度的配对检验结果:P=0.494;受试者桡侧的角度配对的t检验结果:P=0.309;受试者尺桡活动度的配对t检验结果:P=0.187;受试者尺侧偏转度和血清中的类风湿因子水平的相关性检验:r=-0.373,P=0.021;受试者桡侧的偏转度和血清中的类风湿因子的相关性检验:r=-0.509,P=0.003;受试者尺桡侧的活动度与血清中的类风湿因子的相关性检验:r=-0.440,P=0.007。结论类风湿性关节炎患者双侧腕关节的运动障碍程度无统差异,患者腕关节的运动功能和类风湿因子呈负相关。

Objective To judge the joint movement of the subjects of rheumatoid arthritis and its correlation with rheumatoid factor though the application of 320CT motion imaging function.Methods Choice 20 cases of rheumatoid arthritis, and bilateral wrist joint. Study of the wrist joint, and measure the deflection of the ulnar side, the deflection of the radial side, the activity of the ulnar radial side, and the level of serum rheumatoid factor though the application of 320CT motion imaging function.Results Paired test results of the ulnar side of the wrist of the participants： P=0.494. T test results from the angle of the radial side of the receiver： P=0.309. Paired t test results of the ulnar radial activity of the subjects： P=0.187. Correlation test between the ulnar deflection and the serum levels of rheumatoid factor： r=-0.373, P=0.021. The correlation between the radial side of the test and the test of rheumatoid factor in the radial side of the test： r=-0.509, P=0.003. The correlation between the level of activity of the ulnar radial side of the test and the rheumatoid factor in serum： r=-0.440, P=0.007.Conclusion There was no difference in the degree of the movement of the wrist in the patients with rheumatoid arthritis, and there was a negative correlation between the motor function of the wrist and the rheumatoid factor.
