【摘要】 妊娠期高血压疾病是妊娠期特有的疾病,发病率高,对妊娠妇女、胎儿及新生儿危害极大,是导致孕产妇和围生儿死亡率增加的主要原因。近半个世纪,国内外学者对其发病机制进行了大量研究,有过度炎症反应、血管内皮损伤、氧化应激、母胎免疫平衡失调、滋养细胞缺血及遗传基因易感性等学说,但至今病因尚未阐明。众多研究发现,妊娠期高血压疾病具有较高遗传倾向,与某些基因多态性有关,与多基因有关,且更易发生原发性高血压。相关基因的突变可导致基因表达异常,使基因产物出现数量及功能异常,而诱发妊娠期高血压疾病。 更多还原

【Abstract】 Pregnancy induced hypertension(PIH) is a characteristic disease of pregnant women with high morbidity,which does great harm to the pregnant,the fetus,and the newborns.It is one of the main causes of increasing mortality of the pregnant women and the puerperal babies.In nearly half a century,domestic and foreign scholars have done a lot of studies about its pathogenesis,such as producing excessive inflammatory response,endothelial injury,oxidative stress,maternal-fetal immune imbalance,trophoblas... 更多还原
