实验证明皮质类固醇、甲状腺素、一磷酸环腺苷酸(cAMP)、雌激素及催乳素能加速胎儿肺成熟,而胰岛素可抑制肺成熟,糖尿病母亲所生婴儿中的呼吸窘迫综合征(RDS)发病率显著大于同年龄、同体重的对照组。本文研究了脐血胰岛素含量和早产儿RDS发病率的关系。方法采集70例早产儿的脐血。孕龄为27～35周(平均33周),其中14例发生RDS,56例健康。全部病例放射线检查均有典型病变(死亡者有组织学检
Experiments show that corticosteroids, thyroxine, cAMP, estrogen and prolactin can accelerate fetal lung maturation, and insulin can inhibit lung maturation in infants born to diabetic mothers respiratory distress syndrome (RDS) The incidence was significantly greater than the same age, same body weight of the control group. This article studies the relationship between cord blood insulin levels and the incidence of RDS in preterm infants. Methods Umbilical cord blood was collected from 70 premature infants. The gestational age ranged from 27 to 35 weeks (mean, 33 weeks), with RDS occurring in 14 and healthy in 56. Radiographic examination of all cases were typical lesions (dead were organized examination
