Effects of maternal and fetal vascular endothelial growth factor a single nucleotide polymorphisms on pre-eclampsia: A hybrid design study.

Maternal and fetal gene variants play important roles in the pathology of pre-eclampsia (PE), but most studies investigating the associations between vascular endothelial growth factor A (VEGF-A) gene variates and PE focusing on maternal genetic effects. The present study firstly used a hybrid case-parent and control-mother study design investigating the both maternal and fetal effects of VEGF-A gene polymorphisms on PE among Han Chinese pregnant women. This study recruited 221 PE patients with their partners and infants and 345 normotensive women with their infants. The current study found that, in both maternal and fetal dominant model (GC + CC/GG), VEGF-A rs2010963 polymorphism was associated with an increased risk of PE (OR = 1.85, 95% CI: 1.25-2.75; OR = 1.90, 95% CI: 1.28-2.83, respectively). In the log-liner model analyses, offspring carrying the genotype of GC or CC in the rs2010963 polymorphism could increase the risk of maternal PE (OR = 1.84, 95%CI: 1.18-2.86; OR = 1.89, 95%CI: 1.02-3.49, respectively) compared to the offspring with GG. Meanwhile, the present study also found that passive smoking had a significant interaction with maternal rs2010963 polymorphism (PLRT = 0.022) on the risk of PE.

The effect of a web-based training for improving primary health care providers' knowledge about diabetes mellitus management in rural China: A pre-post intervention study.

BACKGROUND: The performance of primary health care providers regarding DM management is poor in rural China, and effective training methods for providers are urgently needed. This study aimed to evaluate the effect of web-based training for improving knowledge about DM management among primary health care providers in rural China and to further compare the effects of the training effect between primary health care providers with different backgrounds. METHODS: A pre-post intervention study was conducted from April to August 2014. In this study, a total of 901 primary health care workers were recruited from six counties in Hubei province. To evaluate the effect of the web-based training, the knowledge achievement of participants was measured with multiple choice questions (MCQ) at baseline, at the end of two weeks of training and at three months after training. A mixed linear model (MLM) was used to measure group differences in the mean scores at baseline and follow-up. RESULTS: After the web-based training, the knowledge scores of the village doctors increased from 73.58 at baseline to 89.98 at posttest and to 84.57 three months after the training. For township health workers, we observed an upward trend in scores from 78.87 at the pre-test to 91.72 at the second test, and at the three months after the training, the scores increased to 94.91. For village doctors, greater knowledge achievement was observed between the scores at baseline and after two weeks of training(adjusted difference: 3.55, P = 0.03) compared to that observed for the township health workers, while decreased their knowledge achievement between baseline and the third-test compared with that of township health workers (adjusted difference: 5.05, P = 0.01). CONCLUSIONS: This study suggested that web-based training was an effective method for improving the knowledge of primary health care providers about management of DM in remote areas. Compared with the effect of the training on village doctors, the training had a poor short-term effect on township health workers but a better long-term effect.
