摘要： 邻苯二甲酸酯（phthalates，PAEs）在生活中广泛存在，是一类典型的环境内分泌干扰物（environmental endocrine disruptors，EEDs）。胎盘富含激素受体，使其对EEDs高度敏感。孕期暴露于PAEs，其代谢物可以透过胎盘，通过干扰激素受体影响胎盘功能。胎盘功能障碍将导致胎儿生长受限，甚至引起胎儿死亡。孕期PAEs暴露与胎盘功能异常相关的机制包括侵润/融合、氧化应激、细胞分化/凋亡、激素分泌和脂质积累等。该文总结了孕期PAEs暴露水平概况，综述PAEs对胎盘功能的影响及相关研究进展，并探讨当前研究可能存在的局限性，为未来深入研究PAEs影响胎盘功能的分子机制提供参考。

Abstract:
Phthalates (PAEs) are widespread in life and are a class of environmental endocrine disruptors (EEDs). The abundance of hormone receptors makes the placenta highly sensitive to EEDs. During pregnancy, women can be exposed to PAEs, and their metabolites can pass through the placenta and affect its function by interfering with hormone receptors.The dysfunction of placenta will result in fetal growth restriction or, if more severe, fetal death. Functional placental disruptions linked to phthalates exposures include invasion/migration, oxidative stress, cell differentiation/apoptosis, hormone secretion and lipid accumulation.In this paper, the exposure level of PAEs during pregnancy is summarized, the mechanism for the effect of phthalates on placenta is reviewed, and the possible limitations of these studies are discussed, aiming to provide insights for further studies on the potential molecular mechanism through which PAEs disrupt placental function.
Key words: phthalate (PAE), environmental endocrine disruptor (EED), prenatal exposure, placental dysfunction
