Referencing documents through ncbi: Import NCBI documents into the endnote: Results Preview window, select "MEDLINE" in the drop-down menu of Display, and select an appropriate value in the drop-down menu of Show to ensure that all required documents can be exported (but only 200 records can be exported at most at a time).

A large number of molecular data and the hidden and complicated patterns of these data make computerized databases and analysis methods absolutely necessary. The challenge is to find new ways to deal with the quantity and complexity of these data, and to provide researchers with better facilities to obtain tools for analysis and calculation, so as to promote the understanding of our genetic things and their roles in health and disease.

Mainly in the following aspects:

① Reflect the author's scientific attitude, which shows that the paper has real and extensive scientific basis, and also reflects the starting point and depth of the paper. Scientific and technological research is inherited, and current research is based on past research. Today's research results or research work are generally the continuation and development of previous research work or research results.

Therefore, it is necessary to evaluate the previous work when expounding the background, reason and purpose of the research. Recording references can not only explain the evidence, but also clearly explain the starting point and depth of the paper. To some extent, this provides an objective basis for reviewers, editors and readers to evaluate the value and level of the paper.

② It is convenient to distinguish the author's achievements from others' research achievements. Although the research results reported in the paper are the author's own, it is inevitable to quote the previous research results in the process of elaboration and demonstration. If you mark the quoted parts, the achievements of others will be clear.
