Generally speaking, comprehensive articles are long, mainly collecting documents or focusing on comments, which are authoritative and can guide the further development of the discipline and are classified as Class A.
In abstracts, case reports, experience exchanges and other articles, it is difficult to unify the article identification code, some of which are designated as B, and some of which should be treated separately according to the specific circumstances of the article. Comments, seminars and other general signs are designated as C; Short medical reports and short stories are generally designated as D.
