The objective of this research was to determine if gestational diabetes has an impact on the plasma lipoprotein profiles and/or cholesterol content of the plasma lipoproteins in newborns. Very low plus low density lipoproteins and high density lipoproteins in cord sera of newborns from gestational diabetic and non-diabetic mothers were isolated by heparin-affinity chromatography, and the cholesterol content in these plasma lipoprotein fractions were measured with an enzymatic assay. There were no significant differences in baby weights and total serum cholesterol levels between the two experimental groups. High density lipoprotein cholesterol levels (p less than 0.05) were significantly lower while very low plus low density lipoprotein cholesterol concentrations (p less than 0.05), very low plus low density lipoprotein cholesterol/high density lipoprotein cholesterol ratios (p less than 0.025), and total serum cholesterol/high density lipoprotein cholesterol ratios (p less than 0.025) were significantly elevated in newborns of diabetic mothers. These results suggest that gestational diabetes altered neonatal plasma lipoprotein metabolism.
本研究的目的是确定妊娠期糖尿病是否会对新生儿血浆脂蛋白谱和/或血浆脂蛋白中的胆固醇含量产生影响。通过肝素亲和色谱法分离妊娠期糖尿病母亲和非糖尿病母亲所生新生儿脐带血清中的极低密度脂蛋白与低密度脂蛋白以及高密度脂蛋白,并用酶法测定这些血浆脂蛋白组分中的胆固醇含量。两个实验组之间的婴儿体重和总血清胆固醇水平无显著差异。糖尿病母亲所生新生儿的高密度脂蛋白胆固醇水平显著降低(p<0.05),而极低密度脂蛋白与低密度脂蛋白胆固醇浓度(p<0.05)、极低密度脂蛋白与低密度脂蛋白胆固醇/高密度脂蛋白胆固醇比值(p<0.025)以及总血清胆固醇/高密度脂蛋白胆固醇比值(p<0.025)则显著升高。这些结果表明,妊娠期糖尿病改变了新生儿血浆脂蛋白代谢。
