Methods: 42 NSCLC patients (NSCLC group) and 40 patients with benign lung lesions (control group) admitted to Shaanxi Provincial People’s Hospital from November 2022 to October 2023 were se-lected. Flow cytometry was used to detect peripheral blood Th17 cell levels in each group, and en-zyme-linked immunosorbent assay (ELISA) was used to measure IL-17 and MMP2 levels in the se-rum. The application value of these three detection indicators in clinical staging and lymph node metastasis of NSCLC, as well as the diagnostic efficacy of their combined detection were evaluated. Results: In the NSCLC group, compared with patients in stages I~II, patients in stages III~IV showed a significant increase in peripheral blood Th17 cell levels, as well as significantly higher serum IL-17 and MMP2 levels, with statistical significance (all p < 0.05); in the NSCLC group, the levels of Th cells, serum IL-17, and MMP-2 were significantly higher in patients with lymph node metastasis compared to those without metastasis, and the differences were statistically significant (all p < 0.05); the accuracy, specificity, and sensitivity of the combined detection of Th17, IL-17, and MMP2 were 95.71%, 93.84%, and 97.22%, respectively. Compared with single detection, they were significantly higher, and the differences were statistically significant (all p < 0.05). Conclusion: Th17 cells, IL-17, and MMP2 are associated with clinical staging and lymph node metastasis in NSCLC, and their combined detection can help in the differential diagnosis of NSCLC.

肺癌是公认的发病率高、预后差的恶性肿瘤,对人类的生命健康构成了巨大的威胁 [
近年的研究中发现一种新型的CD4+效应T细胞即Th17细胞参与了恶性肿瘤的病理发展过程 [
选取陕西省人民医院2022年11月~2023年10月经病理检验确诊的42例NSCLC患者(NSCLC组)及40例肺良性病变患者(良性病变组)为观察对象。NSCLC组纳入标准 [
采用流式细胞术检测各组外周血Th17细胞水平,采用酶联免疫吸附法(ELISA)测定血清中IL-17和MMP2水平,ELISA试剂盒由武汉伊莱瑞特有限公司提供,所有操作严格按照试剂盒说明书进行。
流式细胞检测:空腹抽取患者每人肘静脉血6 ml,其中肝素抗凝血3 mL,用于流式细胞检测;促凝剂处理的血液3 mL,用于ELISA检测。肝素抗凝血采用淋巴细胞分离液密度梯度离心(2000 r/min离心20 min)分离单个核细胞。每组取5 × 104细胞移入至流式管,向流式管中加入荧光抗体FITC-CD3和PerCP-CD4各10 μL,室温避光反应15 min。1500 r/min速率离心5 min,弃上清。在沉淀中加入Fixation/pormeabilization破膜剂1 mL,混匀室温放置20 min。加入PBS洗液2 mL,1500 r/min速率离心5 min,弃去上清液,留下沉淀。加入10 μL荧光标记的PE-IL17进行细胞内染色,避光反应30 min。加入PBS洗液2 mL,1500 r/min速率离心5 min,弃去上清液,留下沉淀。如此重复洗涤两次后,加入500 μL PBS重悬细胞进行流式检测。
ELISA检测:促凝剂处理的血液常温静置2 h,按2500 r/min离心10 min,分离血清。配置不同浓度标准品,然后将标本和不同浓度标准品加入相应板孔,再加入相应的生物标记素进行标记,置于37℃孵育60 min。洗板4次后,分别加入抗人IL-17和MMP2生物素化的抗体进行反应,37℃孵育60 min,加入特异性酶溶液作用后洗板,加入显色液终止反应,测其OD值,通过绘制标准曲线计算得出IL-17和MMP2的含量。
观察指标如下:① 比较Th17,IL-17和MMP2在NSCLC组和良性病变组中的表达。② 比较NSCLC组内I~II期和III~IV期患者Th17、IL-17和MMP表达情况。③ 比较NSCLC组内淋巴结转移和无转移患者Th17、IL-17和MMP2表达情况。④ 计算Th17、IL-17和MMP2单项诊断及三项联合诊断准确度、特异度、敏感度,其中准确度 = (真阳性 + 真阴性)/总例数 × 100%;灵敏度 = 真阳性/(真阳性 + 假阴性 × 100%。特异度 = 真阴性/(真阴性 + 假阳性) × 100%。

NSCLC是一种临床常见的肺部恶性肿瘤,占所有肺癌的80%,具有高发病率和病死率特点 [
本研究中,我们通过流式细胞术检测NSCLC和肺良性病变患者外周血Th17细胞水平,结果显示NSCLC患者外周血中Th17细胞水平明显高于良性病变组,且在NSCLC组中,III~IV期及淋巴结转移患者Th17细胞水平明显升高。这表明Th17细胞容易趋化到肺癌组织内,且在肺癌组织局部呈高表达。有研究发现肿瘤细胞与肿瘤成纤维细胞能分泌趋化因子RANTES与单核细胞趋化蛋白1 (MCP-1),诱导Th17细胞在肿瘤局部聚集增殖 [
MMP2与肿瘤的浸润和转移密切相关,由肿瘤细胞和间质细胞分泌,参与降解3型胶原、纤维黏连蛋白等胞外基质成分 [
同时,本研究结果提示,Th17、IL-17和MMP2联合检测,在NSCLC诊断中的准确度、特异度及灵敏度分别95.71%、93.84%和97.22%,均明显高于单一检测,提示三种指标联合检测的诊断效能较好。
综上所述,Th17、IL-17和MMP2在NSCLC患者中表达异常,并能反映NSCLC临床分期及淋巴结转移程度,且三项联合检测具有较高诊断效能,可为NSCLC诊治提供可靠参考。
