摘要 目的:观察皮肌炎(DM)患者外周血B淋巴细胞剌激因子(BLyS)的含量及其mRNA在外周血单个核细胞(PBMCs)中的表达。方法:ELISA法测定10例皮肌炎患者外周血中BLyS含量.同时采用RT-PCR技术检测BLyS mRNA在PBMCs中的表达情况。并取健康体检者怍对照。结果:皮肌炎患者外周血BLyS为(10.25±1.19)/μg/L,显著高于健康对照组[(3.19±0.65)/μg/L;t=5.186.P<0.01];BLyS mRNA在皮肌炎患者外周血单个核细胞中高表达(0.39±0.04)%,明显高于健康对照组[(0.1 7±0.01)%;t=5.611,P<0.01]。结论:皮肌炎患者外周血中BLyS含量较正常人明显增高,同时伴有PB—MCs BLyS mRNA的高表达,提示BLyS分子水平的改变与皮肌炎的发生发展有着密切关系。
