Résumé

Abstract@#Oral diseases are the most important public health problems that have not received due attention, especially among college students. Based on the analysis of literatures on oral health status and behaviors of college students, the paper systematically summarizes the relevant research situation, points out the existing problems. Suggestions and countermeasures, such as attaching importance to the investigation and research on oral health of college students, improving the quality and level of scientific research on oral health of college students, exploring more effective comprehensive intervention measures for oral diseases and oral health education, should be implemented as projects are put forward, so as to provide basis for improving the oral health status of Chinese college students and promoting relevant research level.

Résumé

AIM: To investigate whether salidroside has influence on the activities of endothelial progenitor cells (EPCs) and its mechanism.METHODS:Mononuclear cells from normal human peripheral blood were cultured in fi-bronectin coated flasks in endothelial progenitor medium .After 7 d, EPCs were characterized as adherent cells with acLDL-DiI uptaking and lectin binding by direct fluorescent staining .The proliferation and migration of EPCs were analyzed by MTT assay and Transwell chamber assay , respectively.The EPCs adhesion assay was performed by re-plating the cells on fibronectin-coated dishes , and then adherent cells were counted .NO and Akt protein were also detected .RESULTS:Sali-droside promoted EPCs proliferative , migratory and adhesive capacities in a concentration dependent manner .Salidroside also increased NO secretion , and the level of phosphorylated Akt protein .However , the effects of salidroside on EPCs were inhibited by phosphoinositide 3-kinase inhibitor LY294002.CONCLUSION:Salidroside regulates the activity of EPCs by phosphoinositide 3-kinase/Akt signaling pathway .

Résumé

Purpose:Cochlear implant is a sort of device which is used to restore normal heating for the profoundly deaf by electrical stimulation of the auditory nerve.Simulation of multiple channels demonstrates that the number of channels has significant influence on sound effect.Method:This paper reviews the Continuous Interleaved Sampling (CIS) strategy for cochlear implants,and simulates it in PC.The audible sound of cochlear implanter is synthesized,and preliminary analysis of the speech identification rate of CIS strategy in different channels has also been done based on the simulation.Result:CIS strategy using 6 or 8 channels can achieve better sound effect .Conclusion:Simulation results show that CIS strategy with envelope extraction and high number of channels can produce satisfactory speech synthesis effect

Résumé

The examination question database on Nutrition and Food Hygiene was set up and applied to reduce the effects of subjective factors on test efficacy.The test items of noun explanation,brief answer and discussion were compiled in the form of Microsoft Excel.Then the items were classified by Excel filtration function and a test paper was created by random sampling from the database.It reduces teachers' burden of making test questions and increases objectivity of test questions,which has achieved good results in teaching.
