目的:研究产妇尿液中邻苯二甲酸酯类( PAEs)物质代谢物的水平与11β-羟基类固醇脱氢酶(11β-HSD2酶)活性的关联,初步探索PAEs影响胎儿宫内发育的可能机制。方法2012年采用单纯随机抽样法抽取宫内发育迟缓( IUGR)新生儿33例,并匹配正常对照新生儿33名,采用高效液相色谱-串联质谱法测定产妇尿液中4种PAEs代谢物,即邻苯二甲酸单丁酯( MBP)、邻苯二甲酸(2-乙基己基)单酯(MEHP)、邻苯二甲酸(2-乙基-5羟基己基)单酯(MEHHP)、邻苯二甲酸(2-乙基-5氧己基)单酯( MEOHP )和3种皮质醇皮质酮代谢物,即四氢皮质醇( THF )、allo-四氢皮质醇( allo-THF)、四氢皮质酮( THE)的含量,并分析产妇尿液中PAEs代谢物的水平与11β-HSD2酶活性的关联。结果66名产妇尿液样本中MBP、MEHP、MEHHP、MEOHP代谢物的检出率分别为98%(65名)、89%(59名)、91%(60名)、91%(60名);病例组母亲尿液样本中MBP、MEHHP、MEOHP和DEHP合计( SumDEHP)的中位数分别为31.20、24.61、11.72和48.67 ng/ml,高于对照组(分别为17.32、12.03、5.68和28.64 ng/ml),差异均具有统计学意义( P值均<0.05);病例组母亲体内11β-HSD2的活性[(THF+allo-THF)/THE=(0.79±0.09) ng/ml]低于对照组[(THF+allo-THF)/THE=(0.58±0.04) ng/ml];男婴母亲尿液中MBP(β′=1.12)、MEHHP(β′=1.14)、MEOHP(β′=1.10)、SumDEHP(β′=1.08)的含量与11β-HSD2的活性呈负相关,差异有统计学意义( P值均<0.05)。结论 PAEs可能通过抑制11β-HSD2的活性影响胎儿宫内发育。

Objective To study the association between phthalate esters ( PAEs ) metabolites in maternal urine and 11beta-hydroxysteroid dehydrogenase type 2(11β-HSD2 ) enzyme activity, explore the possible mechanism of PAEs effect on fetal development.Methods All of 33 cases of intrauterine growth retardation ( IUGR) newborn were selected by random sampling in 2012.And 33 cases of normal control newborn were enrolled , use high performance liquid chromatography-tandem mass spectrometry method was used to detect 4 kinds of phthalate esters ( PAEs) metabolites in maternal urine:mono-n-butyl phthalate ester (MBP), mono (2-ethylhexyl) phthalate (MEHP), mono (2-ethyl-5-hydroxyhexyl) phthalate(MEHHP), mono ( 2-ethyl-5-oxohexyl ) phthalate ( MEOHP ) and three kinds of cortisol corticosterone metabolites , tetrahydrocortisol (THF), allo-tetrahydrocortisol (allo-THF), tetrahydrocortisone (THE), and analyze the association between phthalate esters ( PAEs) metabolites in maternal urine and 11β-HSD2 enzyme activity.Results MBP,MEHP,MEHHP,MEOHP metabolites can be detected in 98%(65 cases),89%(59 cases), 91%(60 cases),91%(60 cases)of all 66 maternal urine samples, respectively.The median concentrations of test material in case group were 31.20 ng/ml for MBP, 24.61 ng/ml for MEHHP, 11.72 ng/ml for MEOHP and 48.67 ng/ml for SumDEHP which were significantly higher than those of the control group ( were 17.32,12.03,5.68 and 28.64 ng/ml); 11β-HSD2 activity in case group (( THF +allo-THF)/THE =(0.79 ±0.09) ng/ml) was significantly lower than that of the control group (( THF+allo-THF)/THE=(0.58 ±0.04) ng/ml);PAEs metabolites MBP(β′=1.12),MEHHP(β′=1.14),MEOHP(β′=1.10), SumDEHP (β′=1.08 ) in baby boy mother′s urine was reversely correlated to 11β-HSD2 activity.Conclusions PAEs could affect fetal development by inhibit 11β-HSD2 activity.
