Methods: A total of 2063 pregnant women who met the inclusion criteria were selected as the subjects from February 2016 to April 2017 in Jiading District Maternal and Child Health Hospital of Shanghai and Pudong New Area Maternal and Child Health Hospital. According to the birth weight of the neonates, the neonates were divided into the macrosomia group (neonatal weight > 4000 g, n=125) and the normal infant group (2500 g < neonatal weight < 4000 g, n=1938).The general data of age, number of pregnant women, BMI before pregnancy, gestational diabetes mellitus, glucose tolerance, weight gain during pregnancy, birth weight and gestational week were compared between the two groups. Multivariate logistic regression was used to analyze the risk factors of macrosomia. Results: ①There were significant differences in BMI, glucose tolerance, fasting blood sugar, weight gain in the second trimester, weight gain in the third trimester, birth weight and gestational week between the two groups (P<0.05). ②Single factor analysis showed that pre-pregnancy BMI, gestational week at first diagnosis, fasting blood glucose tolerance, weight gain in the second trimester, weight gain in the third trimester, gestational week and birth weight were the influencing factors of macrosomia (P<0.05). ③Multi-factor analysis showed that gestational weeks, gestational diabetes, fasting glucose tolerance and weight growth in the second trimester were the main factors affecting the production of macrosomia, among which gestational diabetes was the protective factor, while gestational weeks, fasting glucose tolerance and weight growth in the second trimester were the risk factors. Conclusion: The high risk factors for macrosomia are gestational weeks, glucose tolerance, fasting blood sugar and weight gain in the second trimester of pregnancy.We should strengthen regular obstetric examination, health care during pregnancy, reasonable diet and proper exercise, and strictly control the weight gain during the second trimester of pregnancy. At the same time, we should monitor blood sugar in time so as to reduce the incidence of macrosomia.展开更多

The difference of sFlt-1/PLGF ratio in the urine was compared between the two groups of pregnant women, and the expression levels of invasion-related genes and apoptosis-related genes in the placental tissues were detected. The Pearson test was adopted to further evaluate the correlation of urine sFlt-1/PLGF ratio with abnormal trophoblast invasion and apoptosis in pregnant women with preeclampsia.Results: Urine sFlt-1/PLGF ratio of preeclampsia group was significantly higher than that in normal control group;Rho, ROCK, Notch-1, MMP9 and LAMA4 mRNA expression in placental tissues of preeclampsia group were lower than those of normal control group whereas CDKN1C mRNA expression was higher than that of normal control group;Bcl-2 and Survivin mRNA expression in placental tissues of preeclampsia group were lower than those of normal control group whereas Bax, Caspase-3 and Caspase-8 mRNA expression were higher than those of normal control group. Correlation analysis showed that the urine sFlt-1/PLGF ratio of pregnant women with preeclampsia was directly correlated with the expression of placental trophoblast invasion-related genes and apoptosis-related genes in pregnant women with preeclampsia.Conclusion: The sFlt-1/PLGF ratio abnormally increases in the urine of pregnant women with preeclampsia, which can further aggravate the abnormal invasion and apoptosis of placental trophoblast cells.展开更多
