摘　　要：目的研究胶质瘤组织中甲状腺激素受体结合蛋白4(thyroid hormone receptor interacting protein 4,TRIP4)和DNA损伤诱导转录因子4(DNA damage inducing transcription factor 4,DDIT4)水平表达及其与临床病理特征和预后的关系。方法选取2018年2月~2019年2月河北医科大学第一医院收治的94例胶质瘤患者为研究对象。应用免疫组织化学法检测组织中TRIP4和DDIT4蛋白表达。比较不同临床病理特征脑胶质瘤组织中TRIP4和DDIT4蛋白表达。采用Kaplan-Meier生存曲线分析不同TRIP4和DDIT4蛋白表达胶质瘤患者生存预后的差异。单因素和多因素COX回归分析影响胶质瘤患者生存预后的因素。结果胶质瘤组织中TRIP4(68.09%)和DDIT4(65.96%)蛋白阳性率高于瘤旁组织(13.83%,10.64%),差异具有统计学意义(χ^(2)=57.212,60.866,均P<0.05)。胶质瘤组织中TRIP4与DDIT4蛋白表达呈显著正相关性(r=0.722,P<0.05)。WHO分级Ⅲ级、肿瘤直径≥3cm胶质瘤组织中TRIP4和DDIT4蛋白阳性率均高于WHO分级Ⅰ~Ⅱ级、肿瘤直径<3cm胶质瘤组织,差异具有统计学意义(χ^(2)=6.393~14.754,均P<0.05)。TRIP4阳性表达组和阴性表达组三年总体生存率分别为37.50%(24/64),66.67%(20/30),TRIP4阳性表达组三年累积生存率低于阴性表达组,差异具有统计学意义(Log-rankχ^(2)=5.949,P=0.015)。DDIT4阳性表达组和阴性表达组三年总体生存率分别为37.10%(23/62),70.00%(21/30),DDIT4阳性表达组三年累积生存率低于阴性表达组,差异具有统计学意义(Log-rankχ^(2)=7.642,P=0.006)。肿瘤直径≥3cm(HR=1.614,P=0.000),WHO分级Ⅲ级(HR=1.790,P=0.000),TRIP4阳性表达(HR=1.665,P=0.000),DDIT4阳性表达(HR=1.476,P=0.000)是影响胶质瘤患者生存预后的独立危险因素。结论胶质瘤组织中TRIP4和DDIT4蛋白表达升高,两者与肿瘤直径及WHO分级相关,是潜在的评估胶质瘤预后的肿瘤标志物。Objective To study the expression of thyroid hormone receptor binding protein 4(TRIP4)and DNA damage inducing transcription factor 4(DDIT4)in glioma tissue and their relationship with clinical pathological characteristics and prognosis.Methods 94 glioma patients admitted to the First Hospital of Hebei Medical University from February 2018 to February 2019 were selected as the research subjects.The expression of TRIP4,DDIT4 proteins in tissues were detected by immunohistochemistry.The relationship between the expression of TRIP4,DDIT4 proteins in glioma tissues and clinical pathological characteristics were compared.The differences in survival prognosis of glioma patients with different levels of TRIP4,DDIT4 protein expression were analyzed by Kaplan-Meier survival curve.Univariate and multivariate COX regression analysis was conducted to analyze the factors affecting the survival prognosis of glioma patients.Results The positive rates of TRIP4(68.09%),DDIT4(65.96%)proteins in glioma tissues were higher than those in adjacent tissues(13.83%,10.64%),with statistically significant differences(χ^(2)=57.212,60.866,all P<0.05).There was a significant positive correlation between TRIP4 and DDIT4 protein expression in glioma tissues(r=0.722,P<0.05).The positive rates of TRIP4(83.64%vs 46.15%,80.00%vs 51.28%)and DDIT4(80.00%vs 46.15%,76.36%vs 51.28%)proteins in glioma tissues with tumor diameter≥3cm,WHO grade III were significantly higher than those in tissues with tumor diameter<3cm,WHO grade Ⅰ~Ⅱ(χ^(2)=6.393~14.754,P<0.05).The 3-year overall survival rates of the TRIP4 positive and negative expression groups were 37.50%(24/64)and 66.67%(20/30),respectively.The 3-year cumulative survival of the TRIP4 positive expression group was significantly lower than that in the TRIP4 negative expression group(Log-rankχ^(2)=5.949,P=0.015).The 3-year overall survival rate of DDIT4 positive and negative expression group was 37.10%(23/62)and 70.00%(21/30),respectively.The 3-year cumulative survival of the DDIT4 positive expressi
