被动吸烟的孕妇体内生物标志物的检测与分析

目的通过检测被动吸烟的孕妇体内生物标志物,研究被动吸烟对孕妇及胎儿健康的影响。方法采用自制问卷,由236个孕妇自填问卷的形式,进行被动吸烟相关信息的问卷调查,调查同时收集孕妇唾液、静脉血、尿和脐带血,将所调查的236名孕妇按被动吸烟量分为无被动吸烟、被动吸烟量<10支/d、10支/d≤被动吸烟量<20支/d和被动吸烟量≥20支/d共4个组,用吡啶-巴比妥酸法测定唾液硫氰酸盐含量,用巴比妥酸比色法测定孕妇静脉血、尿及脐带血可铁宁含量。结果不同被动吸烟量各组孕妇唾液硫氰酸盐含量差异有统计学意义,随着被动吸烟量的增加,唾液中硫氰酸盐含量升高;各组间静脉血、尿、脐带血可铁宁含量差异分别亦有统计学意义,随着被动吸烟量的增加,静脉血、尿、脐带血可铁宁含量升高。结论静脉血、尿、脐带血可铁宁含量是孕妇被动吸烟的体内生物标志物,孕妇被动吸烟可对自身及胎儿的健康产生影响。

Detection and Analysis of Biomarker of Pregnant Woman Subjected to Passive Smoking

Objective To investigate the influence of passive smoking to pregnant woman's and fetus's health by the detection of biomarker. Methods A questionnaires about passive smoking made by ourselves were answered by 236 pregnant women including quantity and the number of year of smoking in the family and working places. At the same time pregnant woman's saliva, venous blood, urine and umbilical cord blood were collected. The sulphocyanate in their saliva was determined with pyridine-barbiturate method; the cotinine in venous blood, urine and umbilical cord blood were determined with barbiturate method. Results The content of sulphocyanate in saliva was different upon the quantity of passive smoking of pregnant women; there were significant differences had been seen among groups of passive smoking in cotinine in venous blood, urine and umbilical cord blood. Conclusion The contents of cotinine in venous blood, urine and umbilical cord blood are biomarkers of pregnant woman subjected to passive smoking, and passive smoking of pregnant woman will influence the health of pregnant woman and fetus.
