摘　　要：目的探讨结肠癌合并2型糖尿病(T2DM)患者血清长链非编码RNA INK4基因座中反义非编码RNA(lncRNA ANRIL)、微小RNA-181b-5p(miR-181b-5p)的表达及其与淋巴结转移的相关性。方法选取2019年5月—2022年8月本院收治的117例结肠癌合并T2DM患者为结肠癌合并T2DM组,并根据患者淋巴结转移情况将其分为淋巴结转移组56例和淋巴结未转移组61例。另选取同期体检的健康志愿者117例为对照组。采用反转录实时定量PCR检测血清lncRNA ANRIL、miR-181b-5p的相对表达水平。采用Logistic回归分析探讨影响结肠癌合并T2DM患者淋巴结转移的因素。绘制受试者工作特征(ROC)曲线分析血清lncRNA ANRIL、miR-181b-5p水平对结肠癌合并T2DM患者淋巴结转移的诊断价值。采用Pearson相关分析探讨结肠癌合并T2DM患者血清lncRNA ANRIL与miR-181b-5p表达的相关性。结果与对照组比较,结肠癌合并T2DM组患者血清lncRNA ANRIL水平升高,miR-181b-5p水平降低,差异均有统计学意义(P<0.01)。与淋巴结未转移组比较,淋巴结转移组患者血清lncRNA ANRIL水平升高,miR-181b-5p水平降低,差异均有统计学意义(P<0.01)。淋巴结转移组与淋巴结未转移组患者TNM分期、分化程度以及糖化血红蛋白(HbA1C)比较,差异有统计学意义(P<0.05)。糖尿病史、TNM分期、分化程度、HbA1C以及lncRNA ANRIL均是淋巴结转移的影响因素(P<0.05),miR-181b-5p是影响淋巴结转移的保护因素(P<0.05)。血清lncRNA ANRIL与miR-181b-5p水平呈负相关(r=-0.440,P<0.001)。ROC曲线结果显示,血清lncRNA ANRIL、miR-181b-5p以及二者联合诊断淋巴结转移的曲线下面积(AUC)分别为0.800、0.837、0.930,联合诊断价值显著高于lncRNA ANRIL(Z=2.956,P=0.003)、miR-181b-5p(Z=2.117,P=0.034)单独诊断价值。结论结肠癌合并T2DM患者血清lncRNA ANRIL水平升高,miR-181b-5p水平降低,且二者与淋巴结转移具有一定相关性。Objective To investigate the expressions of long non-coding RNA antisense non-coding RNA in the INK4 locus(lncRNA ANRIL)and microRNA-181b-5p(miR-181b-5p)in the serum of patients with colon cancer complicated with type 2 diabetes mellitus(T2DM)and their correlations with lymph node metastasis.Methods A total of 117 patients with colon cancer complicated with T2DM in the hospital from May 2019 to August 2022 were selected as colon cancer with T2DM group and divided into lymph node metastasis group(n=56)and no lymph node metastasis group(n=61)according to the lymph node metastasis status.Additionally,117 healthy volunteers with physical examinations in the same period were selected as control group.Reverse transcription real-time quantitative PCR was used to detect the relative expression levels of serum lncRNA ANRIL and miR-181b-5p.Logistic regression analysis was conducted to explore the factors influencing lymph node metastasis in patients with colon cancer complicated with T2DM.Receiver operating characteristic(ROC)curve was plotted to analyze the diagnostic values of serum lncRNA ANRIL and miR-181b-5p levels for lymph node metastasis in patients with colon cancer complicated with T2DM.Pearson correlation analysis was used to investigate the correlation between serum lncRNA ANRIL and miR-181b-5p expression in patients with colon cancer complicated with T2DM.Results Compared with the control group,patients in the colon cancer with T2DM group had significant increased serum lncRNA ANRIL level and decreased miR-181b-5p level(P<0.01).Compared with the no lymph node metastasis group,patients in the lymph node metastasis group had significant increased serum lncRNA ANRIL level and decreased miR-181b-5p level(P<0.01).There were significant differences in TNM stage,degree of differentiation,and glycated hemoglobin(HbA1C)between the lymph node metastasis group and the no lymph node metastasis group(P<0.05).History of diabetes,TNM stage,degree of differentiation,HbA1C,and lncRNA ANRIL were influencing factors for lymph no
