Objective:This paper aims to explore the relationship between the residents’ health and economic de-velopment to provide a scientific basis which will promote the coordinated economy and health development. Methods:Adopting the entropy method, we could calculate the comprehensive health evaluation index. In combining the co-inte-gration and error correction models, we could analyze the long-term and short-term relationships between our country residents’ level of health since 2000 and the national macro-economic development information. The Granger causality test served as a good method used in testing the casual relationships. Results: The health and economic development has a co-integration relationship which is -0. 6216 in the short-term correction. The economic development extent is the Granger cause of residents’ health status. Conclusion:There is not only a long-term equilibrium, but also a short-term relationship between the residents’ health and economic development in our country. The economic growth pro-motes residents’ health status while the promotion of residents’ health to economic growth is not obvious.

Objective To investigate the application and effect of blended learning in epidemiology course.Methods The 83 nursing undergraduates in one class of grade 2016 were enrolled as experimental group and the 122 nursing undergraduates in another class were enrolled as control group.The undergraduates in the experimental group received blended learning in epidemiology course,and those in the control group received traditional teaching.An anonymous questionnaire survey was performed after the course ended,and the teaching effect was assessed based on the score of a non-standard answer examination and the degree of recognition of comprehensive ability cultivation.SPSS 18.0 was used for data analysis,and the t-test and the chi-square test were used for comparison of data between groups.Results The experimental group had a significantly higher total score than the control group [(85.55 ± 10.49) vs.(80.07 ± 9.47),t=3.897,P=0.000].Compared with the control group,the experimental group had a significantly higher degree of recognition of independent learning ability,cooperative ability,knowledge application,and problem-solving ability after blended learning (P＜0.05).Conclusion Blended learning can be applied in epidemiology course,and its teaching effect is accepted by students.
