为测定小于胎龄儿脂质代谢的变化是否可鉴别胎儿生长迟缓,选择足月婴儿(AGA)25例,小于胎龄儿(SGA)38例。AGA组是足月分娩于1998年3月16～20日,无围产期并发症,SGA38例根据体质指数分为二组,体质指数的计算方法如下:[体重(g)÷(头顶～足后跟长度)~3]×100,脐动脉血在分娩期收集,血液凝固后400转离心10min,分离血清置一20℃待检。测定血清中总脂质(TL)浓度,三组间进行比较,并测定游离脂肪酸(FFA)、二脂酸甘油酯及甘油三酯(TG),洗胎后每个脂组定量及计算均值±标准差。阿朴脂蛋白A-1由西欧免疫吸附分析,白
To determine if changes in lipid metabolism in infants younger than gestational age can identify fetal growth retardation, 25 full-term infants (AGA) and 38 infants less than gestational age (SGA) were selected. AGA group was full-term delivery in March 16, 1998 to 20, no perinatal complications, SGA 38 cases were divided into two groups according to body mass index, body mass index is calculated as follows: [weight (g) ÷ (head ~ foot Followed by the length) ~ 3] × 100, umbilical artery blood collected during childbirth, 400 after centrifugation 10 min blood coagulation, the serum was set at 20 ℃ pending. The concentration of total lipids (TL) in serum was measured and compared among the three groups. Free fatty acid (FFA), diglyceride and triglyceride (TG) were measured. After washing, Standard deviation. Apolipoprotein A-1 was analyzed by Western European immunosorbent assay, white
