简介：目的研究肺癌病人血清中Th1／Th2细胞因子水平，为分析肺癌的发生发展状况和临床治疗提供免疫学指标。方法用流式细胞小球微阵列术(CBA)检测45例肺癌病人血清中Th1／Th2细胞因子水平，以70例正常人为对照。结果45例肺癌病人血清中Th1细胞因子水平分别为：IFN-γ(25．1±18．1)pg/mL、IL-2(1．58±1．69)pg／mL；Th2细胞因子水平分别为：IL-10(4．12±2．22)pg/mL、I-一5(3．21±1．48)pg／mL、IL-4(4．72±2．72)pg／mL；Th1细胞因子IL-2与Th2细胞因子IL-10比值为0．48±0．53。与正常相比，肺癌病人血清中Th2细胞因子IL-5、IL-4均升高，差异有显著性，P＜0．01，IL-10略有升高，但差异无显著性；Th1细胞因子IFN-γ升高、IL-2则明显降低，差异均有显著性，P＜0．01；Th1细胞因子IL-2与Th2细胞因子IL-10比值明显下降，差异有显著性，P＜0．01。肺癌患者各组织类型、TNM分期之间细胞因子表达水平差异均无显著性。结论肺癌病人血清中Th1／Th2比例失调，表现为Th2细胞因子明显升高，Th1细胞因子IL-2降低，提示肺癌病人体液免疫功能亢进，以IL-2介导的细胞免疫功能受抑制。IFN—γ在肺癌病人血清中明显升高，可能在肺癌的发生、发展中扮演了双重角色，既有促进抗肿瘤的作用，又与肿瘤的浸润转移相关。

简介：目的从转录组水平筛选食管癌淋巴结转移相关基因，为深入研究食管癌淋巴结转移提供线索。方法利用癌症和肿瘤基因图谱（TCGA）数据资源，采用随机森林分类方法从转录水平分析、筛选食管癌淋巴结转移相关基因，并对其进行功能聚类。结果获得了与食管癌淋巴结转移相关基因的相关显著性排序，分析获得的重要相关基因集的功能主要集中在细胞代谢及DNA修复、转录等的调控上，并在其中获得了与食管癌淋巴结转移密切相关的代谢及DNA调控领域中的重要节点基因。结论Heatmap图显示获得一簇明显的淋巴结转移相关基因，聚类分析显示这些基因主要集中在代谢和DNA调控等功能上，网络分析获得了KRAS、PPMB、PPP3CA、ATR、WRN、TOP2B等与食管癌淋巴结转移相关的重要节点基因。
