Objective StandardizationTo explore a novel special technique intensive mode (STIM) of teaching cardiac conduction system mapping skills. This method includes theoretical lecture, in vivo operation, 5-whys methods of analyses, intensive-problem oriented trainings, and assessments. Methods Ten post-graduates majoring in cardiology who have equivalent education backgrounds and technical levels were randomly divided into two groups (n=5 per group). All participants underwent a skill training on cardiac electrophysiology mapping, with one group training under the STIM and the other group under the traditional "theory-practice-test" (TPT) mode. The effect of these two educational techniques were evaluated at the end of the training. Results Postgraduates in the STIM group had a more solid grasp of the anatomical position and structure of the cardiac conduction system than those in the TPT group. During in-vivo operation, the students in the STIM group reconstructed and interpreted the electroanatomical maps, voltage maps, electric excitation maps, and electric conduction maps more accurately and quickly than those in the TPT group. Conclusion The STIM teaching mode more effectively improved the basic surgical skills of postgraduates, stimulated the students' learning initiative, and improved the quality of education. STIM is a kind of intensive teaching mode of special skills, and is worth widely implementing in the education of postgraduates majoring in cardiovascular diseases.

The ideological and political content of the laboratory animal science degree course with the basic task of "cultivating morality and cultivating people" is organically integrated into the teaching system of laboratory animal science. It can have a subtle influence on students' thoughts and behaviors. Combined with the curriculum design and professional characteristics of laboratory animal science, this article discussed the ideological and political elements contained in this course, proposed the forms and methods of integrating ideological and political elements into the curriculum design in each chapter. Additionally, the typical cases and characteristic practices of the organic connection of ideological and political education in the teaching system of laboratory animal science were summarized. Practice has proved that integrating the ideological and political elements into the teaching system of laboratory animal science can enhance teacher's awareness and ability of politics, thus effectively improving the compre-hensive quality of students and enhancing the effectiveness of ideological and political education in laboratory animal science.

Animal experiment of operative surgery is a compulsory course for medical students and an important basic course for surgical practice teaching, which is of great importance to the cultivation of clinical medical talents. Combining the teaching practice experience of Shanghai Jiao Tong University School of Medicine, this paper analyzed the common problems in domestic medical universities, and put forward the optimized measures including adjusting and enriching teaching contents, expanding and enriching teaching resources, improving innovative teaching models, constructing scientific evaluation system, and strengthening the construction of teaching faculty, so as to improve the quality of the course and the comprehensive quality of medical students, help cultivate excellent medical talents, and provide references for the teaching reform of animal experiment of operative surgery in medical colleges and universities.

Laboratory animal and laboratory safety management in medical colleges and universities is the basic guarantee for the safe operation of teaching laboratories and serves as an important link for the successful completion of teaching tasks in laboratories. Aiming at the safety status of common experimental animals and laboratories, the Experimental Teaching Center of Basic Medical College of Zhengzhou University trained medical freshmen on the characteristics of experimental animals and laboratory safety knowledge. PowerPoint courses, short video lectures, and flipped classrooms were used for offline training. The training contents included the correct use of experimental animals, safety management and laboratory safety knowledge. After training, an online examination was conducted, which 1 061 freshmen passed, and the passing rate was 99.90%. According to the analysis of the answers of the freshmen in the examination, the error rates of knowledge on microorganisms and dangerous chemicals were 20.35% and 14.89%, respectively. This suggests that training should be strengthened in these two aspects in the future. Through the training, the new medical students mastered the correct use of experimental animals, and their knowledge of laboratory safety increased. This will help to prevent future laboratory accidents.

Medical experimental zoology is a supporting discipline for biomedical research with strong practicality and applicability. Adapting the talent training strategy of medical colleges, cultivating practical and innovative talents, reforming the teaching mode, and improving students' practical abilities are problems that urgently require solutions in the current course of medical experimental zoology. This article aims to explore the teaching advantages and related concepts of the internet interactive platform + sandwich teaching method in the course of medical experimental zoology to improve its teaching quality.

Transgenic animal is very important in medical and biological research fields. Many important investigation leaps in severe diseases are relied on transgenic animals. It is essential to offer a course of transgenic animal technology for graduated students. In present article, we shared a teaching review including teaching material compiling, the course outline, and test reformations to provide a reference and experiences for other colleagues.
