Objective To explore the effect of case teaching method based on ADDIE model in the teaching of surgical nursing. Methods Two classes of the four-year nursing specialty college students (39 students in each class, 78 students in total) in the third grade were selected as samples. According to the principle of randomization, one class was set as the observation group, and the ADDIE model based on case teaching method was adopted. According to the five stages of ADDIE model, namely, analysis, design, development, implementation, and evaluation, the whole process was performed to achieve teaching goals and timely combination of clinical cases, so that the theoretical knowledge of teaching materials and clinical reality were highly connected. The other class was set as the control group. At the end of the semester, the teaching results were evaluated based on two groups of students' test scores and questionnaire findings. SPSS13.0 software was used for statistical analysis. t-test was used to test the significance of the test results,and chi square test was used to test the significance of the survey data. The results of the two teaching methods were compared with the control group. Results The scores of the two groups were significantly higher than those of the control group [(87.0±7.1) vs (78.0±8.6), P=0.000; (93.0±2.4) vs (85.0±3.8), P=0.000]. Significantly more students in the observation group (P<0.05) were satisfied with the teaching methods used to improve the enthusiasm and initiative of learning, improve their interest in learning, broaden their knowledge, improve the effect and efficiency of learning, inspire students to think, associate, and innovate, activate classroom atmosphere, improve the ability of students to analyze and solve problems, apply theories in practice, and accurately grasp the basic concepts and theoretical knowledge. Conclusion The case teaching method based on ADDIE model can effectively improve the teaching quality of nursing courses and improve students' ability to analyze and solve problems. It is well received by students, and it can enhance teachers' teaching skills as well.

The mechanisms of antidepressants are still unclear. There a re two classical theories on monoamine neurotransmitter or on neurotransmitter rec eptors, but both of them can not fully explain the delayed therapeutic action of antidepressants. Recently, many researches have focused on the postreceptor int racellular signal transduction as the mechanism of antidepressant action. G protein is the molecular basis of antidepressants. Neurotransmitter receptors and G protein are the two sectors of their therapeut ic action. They will ultimately influence intracellular signal transduction and result in relative effects such as phosphoration, the induction of neurotrophic factors and neurogenesis. This mechanism suggests a reasonable explanation for t he clinical delaying of antidepressants and it will do great help for the develo pment of antidepressants. It makes the design of novel, safe and more efficaciou s antidepressants possible and provides significant information for the elucidat ion of biology of depression.
