The topic selection of medical scientific research should proceed from the needs of social development, and try to choose topics that are urgently needed to be solved or of great significance in medical and health care. For example, basic medical research and improving the quality of life need to be solved for a long time, and cardiovascular diseases, malignant tumors and other major diseases that endanger human health and threaten life need to be solved urgently in clinical medicine.

2, the principle of innovation

This is a very important principle, which requires that the written paper should not repeat what has been published in textbooks or magazines many times, and draw new conclusions or opinions that others have not found on the basis of science. How to judge whether there is innovation in the process of topic selection? The most important thing is vertical comparison, that is, comparing the previous viewpoints and conclusions, whether there are doubts and difficulties, grasping the doubts and difficulties and trying to solve them; Horizontal comparison, looking for the combination point, whether it is the intersection of disciplines, whether it is an unexplored or blank field of others.

3. Scientific principles

It is required that the topic selection must conform to scientific principles and objective reality, and must be based on scientific theories and objective facts. We should not only respect facts and scientific theories, but also be superstitious about authority and not be bound by traditional concepts. If it violates scientific principles and objective laws, there is no science at all. So, how to judge the scientific nature of the topic? First, whether it is consistent with the existing basic principles; Second, whether there is enough evidence to support the opposition to the current point of view; The third is whether you can take the exam.

4. Feasibility principle

We should consider all the conditions and factors for completing the project and arrange practical projects according to the actual situation. This requires researchers to consider that in addition to technical titles, applicants also need to have certain research experience and ability; Need to have a team with reasonable knowledge and technical structure; Applied research projects need to have some preliminary work accumulation; Have the objective conditions to complete the project (research methods, animal supply, clinical cases, etc.). ).

5. Practical principles

The applicant should focus on obtaining a new product or technology with practical value, and the research results obtained can really treat a disease or improve an unhealthy state.

6. Other principles

In addition to the above principles, we should also abide by the general principles of medical paper selection:

(1) Make the topic as specific and clear as possible, not trivial and isolated.

(2) foster strengths and avoid weaknesses, study their own counterparts and give full play to their own advantages.

③ Choose promising topics, such as research on new disciplines and theories.
