Exploration on the Medical Ethics Education Path of "Combining Moral and Technical Education" of Vocational Medical Students under the Concept of "Three-wide Education" / 中国医学伦理学

The educational purpose of "three-wide education" is in line with the overall goal of talent cultivation in colleges and universities, and fits the development laws of ideological and political work in colleges and universities in the new era. It is an important measure to leverage the joint efforts of education and improve the quality of education. Under the concept of "three-wide education", medical ethics education in higher vocational medical colleges lacks systematization and big data support, medical students’ "knowing morality" and "conducting morality" are not unified, the content of medical ethics teaching is outdated, and teaching methods are single, which is inconsistent with students’ innovative cognitive thinking and derailed from clinical and social real needs, making it difficult to arouse students’ interest in learning. Against the backdrop of continuously improving professional literacy requirements for medical students, this paper explored the medical ethics education path of "combining moral and technical education" for vocational medical students under the concept of "three-wide education", and formed training paths such as "three integration of medical ethics, three progressions of knowledge and action", the coordinated education of ideological and political courses and ideological and political education in the course, the "trinity" of school, family, and society, the innovative multi-dimensional medical ethics education teaching methods, the construction of a medical ethics practice platform, and the establishment of medical ethics cultural education data management platforms, with a view to providing reference ideas for the cultivation of medical ethics among vocational medical students.

Optimization of RAPD Reaction System and Analysis of "HANGQIE-5" Eggplant Generated by Space Mutagenesis / 航天医学与医学工程

Objective To analyze the new breeding of eggplant "HANGQIE-5"(HQ-5) generated by space mutagenesis with RAPD,identify the differential RAPD bands,and try to provide molecular proofs for space mutation breeding.Methods Dry seeds of two eggplants "Tianshuichangqie(TSCQ)" and Longguoyuanqie(LGYQ) were carried by "shenzhou-4" and "shenzhou-3"spaceship.Two mutant lines "TSCQ-MUT-4" and "LGYQ-MUT-4" were selected after four generations of self-cross of TSCQ and LGYQ.A new variety of "HQ-5" was selected by crossing the two lines of "TSCQ-MUT-4" and "LGYQ-MUT-4",which were male and female,respectively.The RAPD reaction system was optimized with orthogonal design and further RAPD analysis was applied.Results The RAPD reaction system was determined as follows: DNA: 40 ng,dNTPs: 7.5 nmol,primer: 10 ng,and rTaq polymerase: 1.25 U.The RAPD results displayed that TSCQ-MUT-4 produced four differential bands compared with its wild type,while LGYQ-MUT-4 produced one,through space flight.Six differential fragments were amplified between HQ-5 and the paternal/maternal.HQ-5 not only shared the common fragments with its parents,but also held some particular ones,which were stably inherited.Conclusion The results indicate that space mutagenesis could cause mutations in DNA of plants,and is helpful to generate a new breeding.
