Analysis on Family History of Diabetes, Weight Gain during Pregnancy and Pre-pregnancy Body Mass Index on 82 Pregnant Women with Gestational Diabetes Mellitus

Objective:To investigate the effects of family history of diabetes mellitus,Gestational Weight Gain(GWG)and Body Mass Index(BMI)before pregnancy on Gestational Diabetes Mellitus(GDM).Method:82 pregnant women with GDM who were hospitalized and delivered in the obstetrics department of our hospital from September 2017 to September 2019 were selected as the observation group,and 60 pregnant women with normal glucose tolerance test in the same period were selected as the control group;The relationship between family history of diabetes,weight gain during pregnancy and pre-pregnancy Body Mass Index and GDM were analyzed.Results:The age,pre-pregnancy weight and weight gain during pregnancy were significantly higher in the observation group than in the control group(P<0.05),and the family history of diabetes and pre-pregnancy Body Mass Index were higher in the observation group than in the control group(P<0.05),and the differences were statistically significant.Conclusion:It is suggested that family history of diabetes is related to gestational diabetes mellitus.Excessive GWG growth during pregnancy and high Body Mass Index before pregnancy may increase the risk of gestational diabetes mellitus in pregnant women.

Linear Strain-Gradient Effect on the Energy Bandgap in Bent CdS Nanowires

尽管在半导体的可能的非同类的紧张效果被调查了因为在一半上世纪和紧张坡度能每在灵活 nanostructures 的测微计是超过 1% ，我们仍然缺乏他们对精力乐队的影响的理解。这里，我们进行紧张坡度的系统的阴极射线发光光谱学研究在在低温度的有弹性地弄弯的 CdS nanowires 的导致的激子精力移动，并且发现在弄弯的 nanowires 的激子精力红移动与紧张坡度成正比，格子失真的一个索引。密度功能的计算在弄弯的 nanostructures 显示出乐队差距减小的一样的趋势并且揭示内在的机制。半导体的乐队差距上的重要线性紧张坡度效果应该在在 nanoelectronics 调节光电子的性质的方法上打开新灯。
