             [摘    要] 目的:分析外周血核苷酸结合寡聚化结构域样受体蛋白 3(nucleotide binding oligomerization domain like receptor
              protein 3,NLRP3)⁃半胱氨酸蛋白酶1(cysteine⁃aspartic acid protease 1,Caspase⁃1)⁃白细胞介素(interleukin,IL)⁃1β信号轴与肺癌
              的相关性。方法:选取 2021 年 6 月—2023 年 8 月江苏省连云港市赣榆区人民医院收治的肺癌住院患者 72 例初诊患者(肺癌
              组)和 72 例健康体检者(健康对照组)。比较两组外周血单核细胞、NLRP3、Caspase⁃1、IL⁃1β水平及肺功能[1 秒用力呼气量
             (forced expiratory volume in one second,FEV1)、用力肺活量(forced vital capacity,FVC)、FEV1/FVC],并分析肺癌组外周血中
              NLRP3、IL⁃1β 水平与FEV1、FVC、FEV1/FVC的相关性。结果:肺癌组患者FEV1、FVC、FEV1/FVC水平均显著低于健康对照组,
              差异有统计学意义(P均 < 0.05);外周血中Nlrp3、Caspase⁃1、Il⁃1β mRNA相对表达水平和Caspase⁃1和IL⁃1β分泌水平均高于健
              康对照组,差异有统计学意义(P均 < 0.05);Spearman相关分析显示,肺癌组患者外周血单核细胞Nlrp3基因mRNA相对表达量
              与 FEV1、FEV1/FVC水平呈负相关(P < 0.05);而外周血IL⁃1β分泌水平与FEV1/FVC水平呈正相关(P < 0.05)。结论:外周血单
              核细胞中NLRP3 mRNA相对表达水平及外周血IL⁃1β分泌水平与肺癌进展呈负相关,可反映肺癌进展程度,对肺癌的筛查和
              诊断具有潜在的参考价值。

             [Abstract] Objective:To analyze the correlation between peripheral blood nucleotide binding oligomerization domain like receptor
              protein 3(NLRP3)inflammasome⁃cysteine protease 1(Caspase⁃1)⁃interleukin 1β(IL⁃1β)signaling axis and lung cancer. Methods:
              From June 2021 to August 2023,72 patients with lung cancer in our hospital(lung cancer group)and 72 healthy subjects(healthy
              control group)were selected. The levels of NLRP3,Caspase⁃1,IL⁃1β in peripheral blood and peripheral blood of lung cancer control
              and healthy group subjects were compared and analyzed. The levels of pulmonary function[forced expiratory volume in one second
             (FEV1),forced vital capacity(FVC),and ratio of forced expiratory volume in the first second to forced vital capacity(FEV1/FVC)]
              were compared. The correlation between peripheral blood NLRP3 and IL⁃ 1β levels and FEV1,FVC and FEV1/FVC was analyzed.
              Results:The levels of FEV 1,FVC and FEV1/FVC in lung cancer group were significantly lower than those in healthy control group(P <
              0.05). The relative mRNA expression levels of Nlrp3,Caspase⁃1 and IL⁃1β,as well as the secretion levels of Caspase⁃1 and IL⁃1β in
              peripheral blood of lung cancer group were significantly higher than those of healthy control group(P < 0.05). Spearman correlation
