Background Identification of modifiable dietary factors, which are involved in the development of gestational diabetes mellitus (GDM), could inform strategies to prevent GDM. Methods We examined the dietary patterns in a Chinese population and evaluated their relationship with GDM risk using a case-control study including 1,464 cases and 8,092 control subjects. Propensity score matching was used to reduce the imbalance of covariates between cases and controls. Dietary patterns were identified using factor analysis while their associations with GDM risk were evaluated using logistic regression models. Results A “vegetable” dietary pattern was characterized as the consumption of green leafy vegetables (Chinese little greens and bean seedling), other vegetables (cabbages, carrots, tomatoes, eggplants, potatoes, mushrooms, peppers, bamboo shoots, agarics, and garlic), and bean products (soybean milk, tofu, kidney beans, and cowpea). For every quartile increase in the vegetables factor score during 1 year prior to conception, the first trimester, and the second trimester of pregnancy, the GDM risk lowered by 6% (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.89 to 0.99), 7% (OR, 0.94; 95% CI, 0.88 to 0.99), and 9% (OR, 0.91; 95% CI, 0.86 to 0.96). Conclusion In conclusion, our study suggests that the vegetable dietary pattern is associated with lower GDM risk; however, the interpretation of the result should with caution due to the limitations in our study, and additional studies are necessary to explore the underlying mechanism of this relationship.

The aim of this study is to test the adhesion of human gingival broblasts (HGFs) and epithelial cells (HGEs) to titanium surfaceby RGD grafting for dental implant, and to obtain an eective perimucosal seal of soft tissue to the implant. RGD peptides werecovalently attached to the titanium surface by CDI activation method to improve the adhesion of gingival cells to the titanium den-tal implants. HGFs and HGEs were inoculated on commercially pure (CP) titanium and RGD-grafted titanium. The number ofattached and proliferated cells was quantied by morphometric analysis using immunouorescence. The results showed that the bio-active peptide RGD was grafted on CP titanium by CDI activation method. The RGD grafting exhibited that the number ofattached and proliferated broblasts and epithelial cells were higher than that on CP titanium. The RGD-grafting is advantageous. to gingival cells adherence to the surface of titanium implant.
