摘要
目的 探讨生长激素 (GH)、胰岛素样生长因子 Ⅰ (IGF Ⅰ )在新生儿期的变化及对新生儿体格发育的影响。方法  5 6例新生儿分成 3组 :A组 (18例 )为早产适于胎龄儿 ;B组 (18例 )为早产小于胎龄儿 ;C组 (2 0例 )为足月适于胎龄儿。各组新生儿按生理需要量满足营养供给 ,分别在生后 3d内、30d时抽取股静脉血检测血GH、IGF Ⅰ水平及血糖值。结果 出生时血IGF Ⅰ水平足月儿大于早产儿 ,早产适于胎龄儿大于早产小于胎龄儿 ,3组间比较均有非常显著性差异 (P均 <0 0 0 1) ,血IGF Ⅰ值与出生体重及胎龄均呈正相关 (P分别 <0 0 0 1,<0 0 1) ;血GH值早产儿略大于足月儿 ,3组间比较无显著性差异 ,GH值与出生体重、胎龄均无相关性(P均 >0 .0 5 )。至生后 30d时血IGF Ⅰ值各组均较出生时明显增加 (P均 <0 0 0 1) ,血IGF Ⅰ的增长值与体重的增长值呈正相关 (P <0 0 1) ;GH值较出生时稍下降 ,差别无统计学意义。出生时血IGF Ⅰ与GH无相关性(P >0 0 5 ) ,30d时血IGF Ⅰ与GH弱相关 (P <0 .0 5 )。各组新生儿抽血同期血糖值均在正常范围。结论 IGF Ⅰ是胎儿发育的主要调控因子 ,也是新生儿期发育的主要调控激素。至生后 30d时 ,GH IGF Ⅰ轴的调控已基本形成。
