Abstract

Acrylamide (AA) is a carcinogenic substance found in food, cigarette smoke and in an environment exposed to acrylamide. This study aims to analyze AA levels in dried blood spot (DBS) samples of lung cancer patients with smoking record, without smoking record, and also in the negative blank. Analysis of AA levels was determined by liquid chromatography tandem mass spectrometry (LC-MS/MS) and DBS extraction using protein precipitation techniques. Mass detection was done using positive electron spray ionization (ESI) and multiple reaction monitoring (MRM) type with / values of 71.99 > 55.23 for acrylamide and / 260.16 > 116.04 for propranolol as the internal standard. AA levels in lung cancer patients with smoking record is in the range of 4.670 g/mL to 11.986 g/mL. AA levels in lung cancer patients without smoking record is in the range of 2.041 g/mL to 12.702 g/mL. Data on AA levels on negative blanks is in the range of 2.72 g/mL to 3.51 g/mL. The results of the independent sample -test ( > 0.05) showed that AA levels in patients with smoking record and those without smoking record did not differ significantly. Then, the Mann-Whitney test was performed between the lung cancer group and the negative blank group and a significant difference was found between the two groups ( < 0.05).

摘要

丙烯酰胺(AA)是一种在食物、香烟烟雾以及暴露于丙烯酰胺的环境中发现的致癌物质。本研究旨在分析有吸烟史、无吸烟史的肺癌患者以及阴性空白对照的干血斑(DBS)样本中的AA水平。采用蛋白质沉淀技术提取DBS样本,通过液相色谱串联质谱法(LC-MS/MS)测定AA水平。使用正离子电喷雾电离(ESI)和多反应监测(MRM)模式进行质谱检测,以丙烯酰胺的m/z值71.99>55.23以及作为内标的普萘洛尔的m/z值260.16>116.04进行质量检测。有吸烟史的肺癌患者的AA水平在4.670μg/mL至11.986μg/mL范围内。无吸烟史的肺癌患者的AA水平在2.041μg/mL至12.702μg/mL范围内。阴性空白对照的AA水平数据在2.72μg/mL至3.51μg/mL范围内。独立样本t检验结果(P>0.05)表明,有吸烟史患者与无吸烟史患者的AA水平无显著差异。然后,在肺癌组和阴性空白对照组之间进行曼-惠特尼检验,发现两组之间存在显著差异(P<0.05)。
