1、宫颈癌患者外周血淋巴细胞亚群分布的差异分析[摘要]目的检测分析宫颈癌患者外周血淋巴细胞亚群的差异分布及临床意义。方法采用流式细胞术检测宫颈癌患者和健康对照成人外周血中CD3+、CD3+CD4+、CD3+CD8+、NK、NKT、CD8+CD28+.CD8+CD28-、CD3+HLA-DR+、CD3-HLA-DR+、Treg细胞的百分比,同时结合宫颈癌患者的临床诊断分期做对比分析。结果与健康对照组比较,宫颈癌患者外周血中CD3+(P二0.0002)和CD3+CD4+T细胞百分比(P=0・0004)以及CD3
2、+CD4+/CD3+CD8+比值(P二0.0256)显著降低;宫颈癌患者CD3+CD8+T细胞百分比与对照组比较无显著差异,但是随着患者临床分期的提高呈降低趋势(P二0.0480)。NK细胞(P〈0・0001)、活化T细胞(CD3+HLA-DR+:P<0.0001)>活化B细胞(CD3-HLA-DR+:P二0.0021)百分比显著提高;细胞毒性T细胞(CD8+CD28+)细胞百分比降低(P二0.0006),抑制性T细胞(CD8+CD28-)百分比提高(P二0.0009);CD4+CD25brightT细
3、胞(Treg)阳性细胞百分比与对照组比较没有显著差异,但CD4+CD25brightT细胞(Treg)在CD4+淋巴细胞中的百分比显著高于对照组(P二0.0335)。宫颈癌患者外周血中CD8+CD28-/CD8+CD28+之比与对照组比较显著提高(P<0.0001)o结论宫颈癌患者细胞免疫功能降低。精确分析宫颈癌患者的T淋巴细胞亚群变化对于临床诊断、治疗和预后评估具有重要的实际意义。[关键词]宫颈恶性肿瘤;淋巴细胞亚群;流式细胞术;肿瘤免疫[中图分类号]R737.3[文献标识码]A[文章编号]1673-
