Objective To investigate the clinical application and effect of micro-planting nail anchorage in orthodontics.Methods Fifty-six patients with oral orthodontic were randomly divided into two groups.29 patients in the observation group were used micro-planting nail anchorage,27 patients in the control group were used the strong non-implant anchorage.Results The reduction of upper incisor inclination and distance in observation group was significantly higher than control group.In another hand,displacement of molars in observation group was significantly lower than control group,the difference was significant(t =9.714,4.491,17.172,all P ＜0.05).Conclusion Micro planting nail can provide the ideal anchorage and orthodontic treatment,and it has the advantages of easy and flexible operation,and it can be instantly afterburner,reliable quality,worthy of clinical application and promotion.

Objective To explore the teaching effects of theory and practice integrated teaching model in small class teaching of ENT nursing. Methods Two classes of nursing students from grade two were randomly selected as experiment group and control group with 120 students in each group. The experiment group was treated with theory and practice integrated teaching model in small class and the control group with traditional practice. The teaching effects of the two groups were compared by test results as well as questionnaire survey . Result The teaching effect in the experiment group was significantly better than that of the control group (P<0.05). Conclusion The theory and practice integrated teaching model in small classes can promote the students' interest in learning and mobilize their initiative and enthusiasm to master theoretical knowledge and specialist skills.

Objective In order to find out certain properate training model for nursing students' ability of general health education.Methods Carried out a one to one teaching model which based on the problem-based learning methods in 900 nursing students,and then evaluated the teaching effects by examination and questionnaire investigation.Results The health education capability of nursing students had promoted significantly,the qualification rate was 100%,nursing students'satisfactory rate for the training model was 100%.Conclusions This training model is feasible and effective in promoting the capability of nursing students in health education.

Huaihua medical College has inquired into the questionnaire from more 500 students who are clinical doctors and graduate nurses and 50 teachs who are clinical teaching hospitals,finding that the results have indicated the significance,the necessity and the actual problems of clinical technical ability practice teaching,when they are in school by their firsthand experience,which are very helpful to shortening scheduled time to practice,improving clinical basic skills,adjusting to medical environment as soon as possible,to ensure practice teaching quality and also have notable effects on continuing reinforcing building the clinical technical ability training centre and improving the quality of clinical technical teaching ability at the same time.

OBJECTIVETo establish a risk early warning model of human infection with avian influenza A (H7N9) virus and predict the area with high risk of the outbreak of H7N9 virus infection.

METHODSThe incidence data of human infection with H7N9 virus at prefecture level in China from February 2013 to June 2014 were collected, and the geographic and meteorological data during the same period in these areas were collected too. Spatial auto regression (SAR) model and generalized additive model (GAM) were used to estimate different risk factors. Afterwards, the risk area map was created based on the predicted value of both models.

RESULTSAll the human infections with H7N9 virus occurred in the predicted areas by the early warning model in February 2014. The early warning model successfully predicted the spatial moving trend of the disease, and this trend was verified by two outbreaks in northern China in April and May 2014.

CONCLUSIONThe established early warning model showed accuracy and precision in short-term prediction, which might be applied in the active surveillance, early warning and prevention/control of the outbreak of human infection with H7N9 virus.
