2、者中有66例ANA阳性(94%),其中43例表现为混合荧光模式。AMA—M2检出率为90%。ANA主要荧光模式对老年PBC患者敏感性88%(62/70),特异性为91.6%(330/360),83.3%ANA滴度≥1:1000,与对照组比较差异有统计学意义(P<0.01o结论老年PBC患者ANA的荧光模型主要为核膜型、核点型、着丝点型、胞浆颗粒型,常表现为混合荧光模型,对于老年PBC具有重要的诊断价值。【关键词】老年人;肝硬化,胆汁性;抗体,抗核;荧光模型【中图分类号】R593.2【文献标识码】A【DOI】10.3724/SP.J.1264.2012.00228Profilesofantinu
