PubMed is a database used to retrieval biomedical literatures. It, however, can’t help us find out the hot topics in recent years. Nowadays, there are some researchers working on the comparative analysis about different tools as same as PubMed, and some other ones bend themselves to data mining on one special field. Our research is finding out the hot topics by analyzing the numbers of publications of some keywords. Here we referred to Time Magazine to list 34 keywords, used Eutilities to get the numbers of publications from PubMed automatically. By analyzing these numbers we can then conclude the hot topics in recent years.
