缺氧诱导因子-1α及Foxp3在结直肠癌组织中的表达及临床意义
Zhongguo shiyan zhenduanxue, 2019 目的检测结直肠癌组织中叉头状螺旋转录因子Foxp3调节性T细胞和缺氧诱导因子-1α(HIF-1α)的表达水平,探讨两者表达水平与结直肠癌患者临床病理特征的关系以及联合检测的临床意义。方法收集2014年1月至2015年1月结直肠患者临床资料,应用免疫组织化学染色检测60例结直肠癌组织和癌旁组织中Foxp3和HIF-1α的表达。结果结直肠癌组织中Foxp3的阳性表达率68.3%(41/60)明显高于癌旁组织阳性表达率21.7%(13/60),两者差异有统计学意义 ...

Zhongguo shiyan zhenduanxue, 2019 结直肠癌是常见的消化道恶性肿瘤。大部分早期结直肠癌预后良好,5年生存率超过90%[1]。腺瘤性息肉与恶性肿瘤的发生发展密切相关。因此,对结直肠息肉等癌前病变尤其是癌变息肉的早期发现与治疗,成为结直肠癌二级预防的关键[2]。近年来,内镜成像技术的发展使早期结直肠癌及癌前病变的准确诊断成为可能。其中,放大 ...

Zhongguo shiyan zhenduanxue, 2021 Lynch综合征（LS）在遗传学中属于常染色体显性遗传病,内部机制是DNA错配修复（MMR）基因即MLH1、MSH2、MSH6和PMS2突变导致微卫星不稳定（MSI）进而引起的遗传性癌症综合征[1]。据文献报道,LS最常见于结直肠癌中,在新诊断病人中约占3%[2],同时在子宫内膜癌、胃癌、尿路上皮癌等也占有一定比例[3]。和散发性结直肠癌相比,Lynch综合征相关结直肠癌（以下简称LS相关结直肠癌）因其内部基因突变,导致肿瘤演变、
