摘要 目的通过检测外周血CD5^+B淋巴细胞及其亚群变化,探讨其与类风湿关节炎(RA)发病及活动的关系。方法采用流式细胞仪技术对RA患者(RA组39例)和健康对照者(对照组18例)外周血CD5^+B细胞(包括CD5^+CD19^+和CD5^+CD20^+亚群)进行定量分析,同时判断RA患者的疾病活动状态。结果外周血CD5^+B细胞在RA组和对照组间差异无统计学意义(P〉0.05)。RA组外周血CD5^+CD19^+和CD5^+CD20^+B细胞亚群百分率显著高于对照组(P〈0.01)。RA活动组患者CD5^+CD19^+和CD5^+CD20^+B细胞亚群百分率与RA非活动组之间差异无统计学意义(P〉0.05)。结论CD5^+CD19^+和CD5^+CD20^+B细胞亚群可能参与RA发病,但与RA的活动无显著关联。
