摘　　要：目的探索血清外泌体miR-205-5p/miR-152-5p联合相对表达量在早期非小细胞肺癌(NSCLC)患者血清中的水平及诊断价值。方法纳入TNM分期为0-Ⅱ期的NSCLC患者(NSCLC组)83例(包括腺癌组55例和鳞癌组28例)和健康对照(对照组)50例,采集血清标本,提取并检测血清外泌体miR-205-5p/miR-152-5p联合相对表达量。比较NSCLC组和对照组的表达量,比较腺癌组、鳞癌组和对照组的表达量,使用多重线性回归分析表达量与性别、年龄、吸烟史、肿瘤大小、淋巴结转移的关联性,采用ROC曲线评价血清外泌体miR-205-5p/miR-152-5p联合相对表达量的诊断效能。结果对照组、NSCLC组、腺癌组、鳞癌组的miR-205-5p/miR-152-5p相对表达量分别为17.76±4.27、20.52±5.51、21.79±5.12、18.02±5.48;NSCLC组高于对照组(t=3.027,P=0.003),腺癌组、鳞癌组、对照组3组间比较差异有统计学意义(F=10.412,P<0.001),腺癌组高于鳞癌组(P=0.001)和对照组(P<0.001),鳞癌组与对照组间差异无统计学意义(P=0.823)。多元线性回归分析结果显示,淋巴结转移情况与相对表达量存在关联性(P=0.037)。对NSCLC的诊断效能评估,曲线下面积为0.671(95%CI:0.579~0.764),截断值为18.493,灵敏度为73.3%,特异度为64.0%。对肺腺癌的诊断效能评估,曲线下面积为0.738(95%CI:0.642~0.883),截断值为18.495,灵敏度为78.2%,特异度为64.0%。对肺鳞癌的诊断效能评估,曲线下面积为0.541(95%CI:0.399~0.684),无统计学意义。结论血清外泌体miR-205-5p/miR-152-5p联合相对表达量在早期NSCLC(主要为早期肺腺癌)患者中升高,对早期NSCLC诊断具有辅助价值。Objective To study the comprehensive expression and diagnosis value of serum exosomal miR-205-5p and miR-152-5p for early non-small cell lung cancer(NSCLC). Methods The objects were divided into the NSCLC group(n=83), which were further divided into the adenocarcinoma group(n=55) and squamous cell carcinoma group(n=28), and the control group(n=50). The TNM stage of NSCLC patients was 0-Ⅱ. Serum samples were collected, the exosomal miRNA were extracted, then the comprehensive expressions of miR-205-5p and miR-152-5p were detected. The comprehensive expression between the NSCLC group and control group, and among adenocarcinoma group, squamous cell carcinoma group and control group were compared. Multiple linear regression was used to analyze the correlation between expression level and gender, age, smoking history, tumor size and lymph node metastasis. The diagnosticvalue of the comprehensive expression of miR-205-5p and miR-152-5p was evaluated with receiver operating characteristic(ROC) curve. Results The comprehensive expressions of control group, NSCLC group, adenocarcinoma group and squamous carcinoma group were 17.76±4.27, 20.52±5.51, 21.79±5.12, and 18.02±5.48, respectively. The expression was significantly higher in the NSCLC group than that in the control group(t=3.027,P=0.003). There were statistically significant differences among adenocarcinoma group, squamous cell carcinoma group and control group(F=10.412,P<0.001). The comprehensive expression of miR-205-5p/miR-152-5p was significantly higher in the adenocarcinoma group than that in the squamous cell carcinoma group(P=0.001) and the control group(P<0.001). The expression in the squamous cell carcinoma group and control group had no difference(P=0.823). Multiple linear regression analysis showed correlation between lymph node metastasis and expression level(P=0.037). For evaluation of diagnostic value of NSCLC, the area under the ROC curve(AUC) was 0.671(95%CI: 0.579-0.764),the cutoff value was 18.493, and the sensitivity and specificity were res
