2、并作IL一21的检测。将179例CHB患者根据HBVDNA水平分为甲、乙两组,甲组86例,HBVDNA水平为10~1O拷贝/ml,乙组93例,HBVDNA水平为1O一1O拷贝/ml,对两组患者进行以上检测指标的比较。结果甲组HBVDNA水平为(4.85±0.37)logl0拷贝/ml,乙组HBVDNA水平为(6.83±0.31)log。。拷贝/ml,t:27.31,P<0.001,甲组Tfh(5.964-1.59)%,高于乙组(3.714-2.15)%,t=4.92,P<0.01,IL一21(42.61±15.11)n#L,高于乙组(14.91±3.15)n
3、#L,t=8.62,P<0.01,HBV特异性CTL(0.364-0.08)%,高于乙组(0.184-0.06)%,t=19.99,P<0.001。结论CHB患者血清HBVDNA水平与外周血Tfh水平有关:HBVDNA水平低者,Tfh水平高,IL一21水平和HBV特异性CTL水平也高。HBVDNA水平高者,Tfh水平低,IL-21水平和HBV特异性CTL水平也低。基线HBVDNA水平影响抗病毒疗效的机制可能与Tfh水平有关。【主题词】肝炎,乙型,慢性;DNA;T淋巴细胞;白细胞介素2;T淋巴细胞,细胞索性RelationshipbetweenserumHBY
