7、内分泌激素代谢状态,现报告如下。1对象和方法1.1对象2001年10月~2003年10月随机抽取我院出生第3天新生儿200例,其中小于胎龄儿100例,足月适于胎龄儿50例,大于胎龄儿50例。研究对象母亲及新生儿均无器质性病变、无缺氧史及孕期并发症、无内分泌疾病及激素服药史。诊断按照实用新生儿学中中国15城市不同胎龄新生儿出生体重值和胎龄简易评分法[1]统一诊断标准。分4组:A组早产小于胎龄儿50例;其中男26例,女24例,孕周平均35.1±1.19周;与足月小于胎龄儿50例,其中男24例,女26例;孕周平均38.46
8、±1.12周比较;B组重度小于胎龄儿49例,男26例,女23例,孕周平均36.12±1.11周;与轻度小于胎龄儿51例,男24例,女27例;孕周平均37.4±1.09周比较;C组小于胎龄儿100例(包括早产、足月小于胎龄儿)与足月适于胎龄儿50例,男28例,女22例,孕周平均38.97±1.07周比较;D组小于胎龄儿100例(同C组小于胎龄儿)
