RESUMO
Objective:To explore the teaching effect of the combined use of curriculum ideological and political education and CDIO (connective, design, implement, operate) mode in the cultivation of stomatological top-notch innovative personnel.Methods:The research subjects were undergraduate students from School of Stomatology, Tongji Medical College, Huazhong University of Science and Technology, who participated in stomatological top-notch innovative personnel training program in 2018 and 2019. CDIO was applied to control group, the combined use of curriculum ideological and political education and CDIO mode was applied to experimental group. After the training, the students' research and innovation capacity was examined and the teaching efficiency of these two models was reflected by the students' questionnaire. SPSS 20.0 software was used for t test. Results:In terms of research and innovation capacity, students scored significantly better in professional English, concluding report, papers publishing, and field defense in experimental group than in control group [(22.43±0.61) vs. (18.49±0.77), (22.48±0.32) vs. (19.05±0.53), (23.69±0.33) vs. (21.89±0.52), and (22.78±0.48) vs. (20.43±0.56), respectively, P<0.05]. The students in experimental group highly agreed with the teaching efficiency of the combined use of curriculum ideological and political education and CDIO mode. Conclusion:The combined use of curriculum ideological and political education and CDIO mode could enhance subjective initiative, sense of identity, sense of pride, sense of belonging, cultivation of multi-dimensional ability, thus helping to form a novel system of stomatological top-notch innovative personnel training.
RESUMO
Cardiovascular disease is still the leading cause of mortality worldwide. Vascular endothelial dysfunction is viewed as the initial step of most cardiovascular diseases. Many studies have indicated that periodontal pathogens, especially Porphyromonas gingivalis, are closely correlated with vascular endothelial homeostasis, but the function of P. gingivalis and the underlying mechanisms are still elusive. To illuminate the effects and elucidate the mechanisms of P. gingivalis on endothelial structural integrity, we developed P. gingivalis infection models in vivo and in vitro. Endothelial cell proliferation, differentiation and apoptosis were detected. Here, we showed that P. gingivalis can impair endothelial integrity by inhibiting cell proliferation and inducing endothelial mesenchymal transformation and apoptosis of endothelial cells, which reduce the cell levels and cause the endothelium to lose its ability to repair itself. A mechanistic analysis showed that TLR antagonist or NF-κB signalling inhibitor can largely rescue the damaged integrity of the endothelium caused by P. gingivalis, suggesting that TLR-NF-κB signalling plays a vital role in vascular endothelial homeostasis destroyed by P. gingivalis. These results suggest a potential intervention method for the prevention and treatment of cardiovascular disease.
