2、86%±2.57%、10.74%4-3.59%,兩組比較P<0.05;血清1FN一水平分別為(5.794-1.28)、(311.00±80.40)pg/mL,兩組比較P均<0.01。觀察組Child-PughA、B、C級外周血co;cDT細胞比例分別為7.98%±2.62%、12.37%±1.73%、13.05%±3.38%,各級間比較P均<0.01;血清IFN一水平分別為(320.10±86.55)、(299.95±60.84)、(307.57±88.43)Pg/mL,各級問比較P均>0.05。CDCD~sT細胞與HBeAg、HBV—DNA相關
3、系數分別為一0.33、一0.44,P均<0.05;IFN一與CDT細胞相關系數為一0.33,P<0.05;cD+8T細胞與IFN一-y相關系數為0.34,P<0.05。結論IFN一水平可反映HBV慢性感染者的免疫狀態(tài),CDcET細胞有助于病毒的清除。關鍵詞:慢性乙型肝炎;CD;cDT細胞;-,/干擾素doi:10.3969/j.issn.1002—266X.2013.44.007中圖分類號:R512.6+2文獻標志碼:A文章編號:1002-266X(2013)44-0020-03LevelsofCD;CD8TcellsandIFN-yinperi
