胎儿炎症反应与早产儿脑损伤

摘要

宫内感染后胎儿炎症反应在早产及早产儿脑损伤中发挥重要作用.胎儿炎症反应表现为胎儿循环中前炎症细胞因子增加.炎症信号可通过血脑屏障启动胎儿神经炎症反应,导致发育中大脑损伤.全面理解胎儿炎症反应有助于提出干预措施并改善早产儿神经发育结局.该文就胎儿炎症反应与早产儿脑损伤相关问题作一综述.%The fetal inflammatory response to intrauterine infection plays a crucial role in the pathogenesis of preterm birth and preterm brain injury.The fetal inflammatory response is characterized by elevated levels of proinflammatory cytokines in the fetal circulation.The inflammation signal is likely transmitted across the blood-brain barrier and initiates a neuroinflammatory response and triggers damage in the developing brain.A better understanding of the fetal inflammatory response will help design interventions to improve neurodevelopmental outcomes after preterm birth.This review summarizes researches of fetal inflammatory response and brain injury in the preterm newborn.
