研究目的:

项目组前期环境流行病学研究发现,母体受孕后的PM2.5暴露可增加人类胚胎停育的发生风险,机制未明。氧化应激及炎症反应是PM2.5致呼吸和心血管疾病的主要机制,是否也介导了PM2.5对胚胎发育的影响有待研究。项目拟依托时间调整土地利用回归模型研究积累、临床一线的病例-对照招募和生物样本采集优势,在预实验基础上开展人体生物标志物检测和人源细胞毒理学实验。测定胚胎停育和正常早孕人群血清及绒毛组织的代表性生物标志物含量,分析PM2.5诱发妊娠早期全身性和母胎界面氧化应激及炎症反应的剂量-效应关系。采集采暖期/非采暖期、交通源/工业源的PM2.5样品,进行人绒毛膜滋养层细胞染毒和干预实验,探索PM2.5及化学组分对细胞氧化应激及炎症反应的影响,筛选出抑制细胞增殖、迁移和侵袭能力的高危化学组分。从母体、组织和细胞水平揭示PM2.5引起人类胚胎停育的效应机制,为采取干预措施预防不良妊娠结局提供科学依据。  

Objectives of Study:

e recently reported that maternal PM2.5 exposures during the post-conceptionperiod could increase the risk of human clinically recognized early pregnancyloss. The mechanisms underlying this association are not yet clear. Oxidativestress and inflammation are the main hypothesized mechanisms of respiratory andcardiovascular diseases caused by PM2.5. Whether these also mediate the effects of PM2.5 on embryonic development remains to be studied. Using our previouslydeveloped temporally-adjusted land use regression PM2.5 models and the advantagesof clinical case-control recruitment and biological sample collection, we intendto conduct human biomarker studies and human cytotoxicity experiments on our basis of pre-experiment. Selected biomarkers in serum and chorionic villous tissue (theprecursor tissue of placenta) will be measured in early pregnancy loss cases andnormal early pregnancy controls. In the epidemiological study, associationsbetween PM2.5 exposure and biomarkers of both systemic and local (at thematernal-fetal interface) oxidative stress and inflammation will be investigated.Further, PM2.5 samples from different periods (heating/non-heating period) anddifferent sources (traffic/industrial source) will be collected. These sampleswill be used in experiments using human chorionic trophoblast cells to assess theeffects of PM2.5 and PM2.5 chemical components on cellular oxidative stress andinflammation, and to screen for especially toxic chemical components that inhibitcellular function. This project will provide insight into the mechanismsunderlying PM2.5-induced human early pregnancy loss at the maternal, tissue andcellular levels. It will also contribute to providing a scientific basis forinterventions to prevent adverse pregnancy outcomes.
