    孕产妇尿中1-羟基芘水平与孕产妇及新生儿hOGG1和XRCC1基因多态性的研究

    Study on the Level of Maternal Urinary 1-Hydroxypyrene and the Polymorphism of Maternal and Neonatal hOGG1 and XRCC1 Genes

    • 摘要:
      目的 探讨乌鲁木齐市孕产妇多环芳烃(polyeyclic aromatic hydrocarbons,PAHs)暴露与孕产妇及新生儿hOGG1和XRCC1基因多态性之间的关系。
      方法 采集乌鲁木齐市某家医院115位孕产妇尿液、静脉血及新生儿脐带血,采用聚合酶链反应—限制性片段长度多态性分析(PCR-RFLP)孕产妇与新生儿的hOGG1和XRCC1的基因位点多态性,采用酶水解—液相色谱—质谱联用仪检测孕产妇尿中PAHs内暴露标志物1-羟基芘(1-OH-P)。
      结果 孕产妇尿中1-OH-P浓度为0.340(0.208~0.555)μg/mmol Cr。孕产妇hOGG1326Ser/Cys基因型不同,体内1-OH-P的浓度也不同(P < 0.05)。携带不同的XRCC1399Arg/Gln基因型新生儿,其母亲体内1-OH-P的浓度存在统计学差异(P < 0.05)。携带不同XRCC1399Arg/Gln基因型的孕产妇,其体内的1-OH-P的浓度差别无统计学意义(P>0.05)。携带不同的hOGG1326Ser/Cys基因型的新生儿,其母亲的体内1-OH-P的浓度无统计学差异(P>0.05)。
      结论 与国内相关研究相比,乌鲁木齐市孕产妇体内的PAHs处于高暴露水平。携带hOGG1326Ser/Cys基因的孕产妇机体在PAHs高暴露环境中DNA损伤更加敏感。

       

      Abstract:
      Objectives To investigate the relationship between maternal polycyclic aromatic hydrocarbon(PAHs) exposure in Urumqi and the polymorphisms of maternal and neonatal hOGG1 and XRCC1 genes.
      Methods A total of 115 maternal urine, venous blood and neonatal cord blood were collected from a hospital in Urumqi, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for gene locus polymorphism of maternal and neonatal hOGG1 and XRCC1. The use of enzymatic hydrolysis-liquid chromatography-mass spectrometry to detect internal exposure marker of PAHs, 1-OH-P, in the maternal urine.
      Results The median level of 1-OH-Pconcentration in maternal urine was 0.340 (0.208~0.555) μg/mmol Cr. The maternal hOGG1326Ser/Cys genotype was different, and the concentration of 1-OH-Pin the body was also different (P < 0.05). There was a statistically significant difference in the concentrations of 1-OH-P in the mothers with neonates carrying different XRCC1399Arg/Gln genotypes(P < 0.05). There was no significant difference in the concentration of 1-OH-P between the parturient carrying different XRCC1399Arg/Gln genotypes (P>0.05). There was no significant difference in the concentration of 1-OH-Pin the mothers with neotates carrying different hOGG1326Ser/Cys genotypes (P>0.05).
      Conclusions Compared with domestic related research, PAHs in parturient in Urumqi were at a high the exposure levels. Maternal bodies carrying the hOGG1326Ser/Cys gene are more susceptible to DNA damage in the high exposure environment of PAHs.
