摘要
目的探讨慢性重型肝炎(CSH)病人外用血单个核细胞(PBMC)内干扰素-γ(IFN-γ)及白细胞介素-4(IL-4)的表达及其临床意义。方法常规分离PBMC,在PMA、Ionomycin、Monensin的刺激下,采用流式细胞术(FACS),对17例CSH患者及19例正常健康者CD4+T细胞内IFN-γ和IL-4的表达进行分析,并应用荧光定量聚合酶链反应检测HBV DNA含量。结果 CD4+Th1、 Th2细胞在CSH组分别为7.2%—26.3%(平均15%)和0、l%—10.9%(平均2.0%),正常对照组则分别为2.2%—11.9%(平均5.9%)和0.4%—3.9%(平均2.2%);CD4+Th1细胞百分数两组间差异有显著意义(P<0.01)。荧光定量PCR结果表明CSH组中13例HBV DNA阳性,其HBV DNA的含量与IFN-γ表达细胞百分数呈负相关。结论 Th1细胞与肝脏的炎症活动明显相关,IFN-γ的表达对HBV复制可能具有一定的影响。
Objective To understand the expressions of interferon-r (INF-r) and interleukin-4 (IL-4) in peripheral blood mononuclear cells (PBMCs) of the patients with chronic severe hepatitis (CSH). Methods PBMCs from the patients with CSH were separated routinely and stimulated by PMA/Ionomycin/Monensin. The production of IFN-r/IL-4 by CD4+ T cells in PBMC was determined by fluorescence activated call sorting (FACS) analysis and fluore scence - quantitative PCR assay for quantification of HBV DNA. Results The percent...
