摘要 为了探讨可溶性白细胞介素-2受体(sIL-2R)对肺癌诊断、分型及分期的价值,我们采用双抗夹心酶联免疫吸附法(ELISA)分别检测肺癌45例,对照者10例支气管冲洗液中sIL-2R和肺癌57例,肺部良性疾病20例,正常对照20例血清中sIL-2R水平。结果示 肺癌患者支气管冲洗液及血清中sIL-2R浓度高于对照组;肺癌血清sIL-2R水平与肺癌分期有关,而与病理组织学类型无关。

Abstract In order to evaluate the value of soluble interleukin-2 receptor(sIL-2R)in the diagnosis,tumor typing,and tumor staging in lung cancer,the concentration,of sIL-2R was tested by EILSA in bronchial lavage fluids(BWF) of 45 cases of lung Cancer patients, 10 cases of control,and in serum samples of 57 cases of lung cancer 20 caese of bengin lung diseases,20 cases of normal control.The results Showed that the levels of SIL-2R in BWF and serum samples of lung cancer patiens were was significantly higher than those of control,the levels of sIL-2R in serum were related to the stage of lung cancer,but not related to the patho-histologic subtype of lung cancer.

白细胞介素-2及其相应的白细胞介素-2受体在人体的免疫系统中占有重要的地位。白介素-2受体主要表达于激活的T细胞表面[1]。细胞膜上的膜白介素-2受体其χ链的膜外肽链脱落下来,形成可溶性白细胞介素-2受体(Soluble interleukin-2 receptor,sIL-2R)进入血循环,也可进入某些体液中。近年来国内外学者对肺癌患者sIL-2R的表达进行研究[2],但对肺癌患者支气管冲洗液中sIL-2R的水平国内外尚未见报道。本文检测肺癌患者支气管冲洗液及血清中sIL-2R的浓度,探讨其对肺癌诊断、分型、分期的价值。
