Objective To overcome disadvantage of double stapler technique in anterior resection of rectum.Method Using single stapleris combined with suture by hand.Results There is no fistula and no death in 52 cases of patients with carcinoma of middle rectum with above methods,and there is 4 fistula and no death in 41 caces of patients with carcinoma of middle rectum using suture by stapler(P

Objective:Based on the theory of demand analysis theory, to build teaching resources of human physiology course and explore its application effect.Methods:The three-year nursing junior college students of Batch 2018 were selected as the research objects. According to the principle of randomization, the students were divided into the observation group (97 cases) and control group (99 cases). Students in the observation group used integrated teaching resources from the perspective of demand analysis, while students in the control group used traditional curriculum resources. After the end of the course, the differences between the two groups of students' theoretical and practical assessment results and teaching experience were compared SPSS 20.0 was used for t test. Results:The results of theoretical [(73.67±8.76) vs. (70.48±8.36)] and practical skills [(84.41±4.83) vs. (83.63±4.27)] in the observation group were significantly different from those in the control group ( P<0.05). The overall scores of 9 teaching effect sub-items, such as learning awareness of inquiry, independent learning ability and critical thinking ability, were significantly higher than those of the control group ( P<0.01). Conclusion:The construction of human physiology teaching resources based on demand analysis theory can improve the effectiveness and pertinence of resource construction, and the effective use of resources in teaching can significantly improve the teaching effect, stimulate students' subjective initiative, cultivate their comprehensive ability and improve classroom efficiency.
