Abstract: By analyzing the distribution of the top 5% of cited papers in Peking University core Chinese medical journals in universities from 2021 to 2023,including the manuscript source,types of literature,number of funds,number of institutions,number of authors,pictures in text,tables,and number of references,we observe and compare the differences in the above characteristic indicators between the top 1% and top 1-5% of cited papers,endogenous and exogenous papers,different types of literature,and the basic situation of the top 10 papers with the highest citation frequency were observed and compared. The characteristics of highly cited papers in Peking University core Chinese medical journals in universities are discussed. The results show that among the highly cited papers in Peking University core Chinese medical journals in universities,there are more endogenous manuscripts,with a high citation rate of guidelines/consensus literature,while exogenous manuscripts are mostly basic research papers. The number of authors per paper is generally four,most of them are completed by two institutions. Each paper has at least one funded project. Generally,there are graphs and tables,and. Other characteristics vary depending on the type of literature. There are no concise rules to follow for the characteristics of highly cited papers. It is necessary to look at the essence through the appearance,and not to evaluate the quality of papers by a single index. The development of university journals is inseparable from the scientific research support of their respective universities. It is necessary to focus on the quality of papers to improve the competitiveness of journals,always put social benefits first,and guide the academic direction.
