Methods From July 2019 to March 2020, pregnant women who had prenatal examinations in Guangzhou Women and Children's Medical Center and Guangdong Family Planning Hospital were selected and divided into GDM group (100 cases) and control group (320 cases) according to FBG level and oral glucose tolerance test (OGTT) results.The age, pre-pregnancy BMI, fasting blood glucose, l h blood glucose after taking sugar, 2 h blood glucose after taking sugar, fasting insulin, 25(OH)D₃ and other indicators of the two groups of pregnant women were measured, respectively, for statistical analysis and comparison. Results The incidence of vitamin D deficiency and deficiency in GDM group was higher than that in control group (P<0.05).There was no significant difference in age and fasting insulin between the two groups (P>0.05).The level of 25(OH)D₃ in the GDM group was lower than that in the control group (P<0.05).Fasting blood glucose, blood glucose at 1 h and 2 h after taking sugar and BMI before pregnancy were all higher in the GDM group than in the control group (P<0.05).Serum 25(OH)D₃ level was negatively correlated with fasting blood glucose and blood glucose at 1 h and 2 h after taking sugar (P<0.05), but not significantly correlated with age, BMI and fasting insulin (P>0.05).The level of 25(OH)D₃ was negatively correlated with the risk of gestational diabetes. Conclusion Reduced serum 25(OH)D₃ levels in the second trimester may increase the risk of GDM, and combined detection of serum 25(OH)D₃ levels in the second trimester is helpful for early prediction of GDM.

Methods Patients who were hospitalized for chest pain from November 2016 to November 2018 were enrolled (n=330). According to coronary angiography,200 patients were divided into SCAD group (n=200),except for the SCAD group, the remaining 130 cases were the control group(n=130). The differences of RDW levels between the two groups were compared, and the correlation between RDW and severity of coronary artery disease (Gensini score) and independent risk factors for SCAD were analyzed.
