In order to search the literature more effectively, medical students need to have a full understanding of the subject and make clear their research goals and needs.

Then, you can adopt the following strategies:

1. Accurately locate keywords: Before searching for literature, you should first make clear your research direction and keywords. The choice of keywords usually includes the name of the disease, treatment methods, drugs, biomarkers and so on.

2. Choose a suitable database: Medical literature is usually distributed in major databases and academic search engines, such as PubMed, MEDLINE, Embase, Google Academic, etc.

3. Reading abstracts and abstracts: Before obtaining the full text of the literature, you can read the abstracts and abstracts first to understand the general content and research direction of the article. If it has nothing to do with your research direction, you can save time without reading the full text.

4. Reasonable use of advanced retrieval function: Most databases provide advanced retrieval function, which can be searched according to specific needs. For example, you can limit the publication time, author, journal name, etc. In this way, you can locate the document you need more accurately.

5. Pay attention to the latest research results: When searching for literature, pay attention to the latest research results, which are usually published in the latest journals. It is recommended to use the periodical query tool of Changxiao Medical Network to screen periodicals, which contains comprehensive periodical information. Through accurate retrieval and screening functions, a more scientific submission scheme can be formulated.
