可铁宁是尼古丁的主要代谢产物之一 ,已成为评估吸烟量的特异性生物标志物。本研究旨在探讨以血中可铁宁水平和自述吸烟状况两项指标综合评估吸烟量的准确性。选取某医院支气管病患者 1 6 6名 (男性98名 ,女性 6 8名 )为研究对象。平均年龄为6 2 3± 1 3 0岁 ( 2 2～ 89岁 )。 Cotinine, one of the major nicotine metabolites, has become a specific biomarker for assessing smoking. The purpose of this study was to investigate the accuracy of the comprehensive assessment of smoking by using two indicators of cotinine level and self-reported smoking status. A total of 166 patients (98 males and 68 females) with bronchial diseases in a hospital were selected as the study subjects. The average age was 623 ± 130 years (range 2 to 89 years).
