摘要: 目的探讨细胞因子诱导的凋亡抑制因子1(CIAPIN1)蛋白在结肠癌组织中的表达及其与肿瘤病理学特征的关系。方法选取我院手术后收集的结肠癌组织标本80例、癌旁组织40例,收集时间2014年1月至2017年1月。采用免疫组织化学染色、Western blotting技术检测两类标本中的CIAPIN1蛋白表达水平,并分析CIAPIN1蛋白与结肠癌发生发展的关系。结果结肠癌组织中CIAPIN1蛋白阳性表达率(30.0%)显著低于癌旁组织(85.0%),差异有统计学意义(χ2=32.303,P<0.001)。结肠癌组织中的CIAPIN1蛋白相对表达水平(0.507±0.183)显著低于癌旁组织(1.874±0.361),差异有统计学意义(t=22.513,P<0.001)。结肠癌组织中的CIAPIN1蛋白阳性表达率与患者年龄(χ2=0.086,P=0.769)、性别(χ2=0.779,P=0.377)、肿瘤浸润深度(χ2=0.879,P=0.348)、肿瘤部位(χ2=0.725,P=0.395)、肿瘤大小(χ2=2.241,P=0.134)、分化程度(χ2=1.372,P=0.241)、病理学类型(P=0.715)无关;与患者淋巴结转移(χ2=10.813,P=0.001)、临床分期(χ2=5.610,P=0.018)具有相关性。结论结肠癌组织中的CIAPIN1蛋白呈显著低表达,并且与患者临床分期、淋巴结转移有关。

Abstract: ObjectiveTo investigate the expression of cytokine induced apoptosis inhibitor 1 (CIAPIN1) protein in colon cancer tissues and its relationship with the pathological features of tumor. MethodsA total of 80 cases of colon cancer tissues and 40 cases of paracancer tissues were collected from our hospital after surgery from January 2014 to January 2017. Immunohistochemical staining and Western blotting were used to detect the expressions of CIAPIN1 protein in the two types of specimens. The relationships between CIAPIN1 protein and the occurrence and development of colon cancer were analyzed. ResultsThe positive rate of CIAPIN1 protein expression in colon cancer tissues was significantly lower than that in paracancer tissues (30.0% vs. 85.0%, χ2=32.303, P<0.001). The relative expression level of CIAPIN1 protein in colon cancer tissues was significantly lower than that in paracancer tissues (0.507±0.183 vs. 1.874±0.361, t=22.513, P<0.001). The positive expression rate of CIAPIN1 in colon cancer tissues was not correlated with the age (χ2=0.086, P=0.769), sex (χ2=0.779, P=0.377), tumor invasion depth (χ2=0.879, P=0.348), tumor location (χ2=0.725, P=0.395), tumor size (χ2=2.241, P=0.134), tumor differentiation status(χ2=1.372, P=0.241), and the pathological type (P=0.715), but was significantly correlated with lymph node metastasis (χ2=10.813, P=0.001) and clinical stage (χ2=5.610, P=0.018). ConclusionThe expression of CIAPIN1 protein in colon cancer tissues reduces significantly, and is correlated with clinical stage and lymph node metastasis.
