How to use the Pubmed database advanced search function

In the first step, let's conduct a preliminary search on this topic. We've determined that its keywords should be"zinc infant growth", enter it into the query box, and press the go key to search. A total of 492 articles were published.

Obviously, if we open and read these documents one by one, it will be a very complicated work. In this case, we need to use advanced search methods to reduce the workload.

Step 2: If the document we want to search is required to reflect relatively recent dynamic developments, then we can click the function key limits button. Enter from in the Publication Date input box"2000 01 01" to"2002 01 01".（"entrez date"means the date of entry into the system; "publication date"Indicate the date of the edition).

Tools Ingredients: ASUS-FX50, Windows 10, browser.

1. Enter in the web bar of the browser, and the following interface will appear.

2. Type abergel in the search box and click "search". As you can see from the graph, there are 623 search results. These search results are all literature with Abergel as the author, and we first skimmed through it and found that none of them have anything to do with dutpase.

3. At this time, you need to type dutpase after dutpase in the search box. At this time, you can see that the search results have been reduced to two. Then carefully read the abstracts and summaries involved in these two articles, and you can find the article you want to query.

<>3. Here we take entering bone as an example, after the input is completed, we click the search pointed by the arrow on the right to retrieve and view.

The pubmed search formula is written as:

1. Open your computer browser and enter the home page of PubMed.

4. In this way, if there is no problem, you can directly click on the relevant link to enter and use PubMed to search for medical literature.

Basic principle: For the input search terms, first search and compare them in multiple index word lists, and automatically convert them into the corresponding mesh subject headings, authors, or journal titles, and then the search terms are displayed in allfields (all fields).

There is a good recall rate, and at the same time to ensure a certain accuracy rate.

For example, the easiest way to find literature on "traumatic cardiac arrest" is to type the word "traumaticcardiac arrest" directly into the search box and click on "sea".

1. First of all, open the browser and open the Souhe Eggplant engine.

<>5. Enter the page after the pure balance search, you can see all the literature, reviews and other articles related to the keyword below, and click on the corresponding article to view, as shown in the figure.

pubmed is a free search engine that provides a database of biomedical searches and abstracts. Its database** is MEDLINE. The core theme is medicine, but it also includes other medical-related fields, such as nursing or other health disciplines.

It also provides a comprehensive resource for biomedical information such as biochemistry and cell biology. The search engine is provided by the National Library of Medicine as part of the Entrez information retrieval system. PubM's information does not include full text of the journal**, but links to full-text providers (paid or free) may be provided.

5. After entering the new interface, find the PDF format on the right side, click PDF, and the document will be displayed in PDF format.

1. Use mesh to expand keywords: mesh is a powerful tool for summarizing synonyms in pubmed. It can avoid the same code answer synonyms, abbreviations are included in the scope of late search, so as to avoid missing the desired literature multiple searches, and greatly improve the search efficiency.

2. Precise lock keywords: for the multi-word phrase entered pubmed, it will query the phrase index, if the corresponding phrase is found, it will be used as a ruler to search for a search term, but if the corresponding phrase is not found, it will be split into a single word and retrieved separately. So Inflammatory Bowel Disease TNF is equivalent to Inflammatory and Bowel and Disease and TNF.

3. Classification viewing: The overall result retrieved by PubMed is unclassified, and the researcher needs to read the classification by himself or use the filter to screen by himself. Therefore, it takes a lot of time and effort to view targeted articles.

However, clinical queries in Pubmed Tools on the PubMed homepage allow researchers to quickly and easily find relevant literature.

4. English journal search: When the journal name or journal ISSN number (international standard journal number) is known, select "NLM CATALOG" in the classification option of the pubmed search box, enter the journal name (limited by quotation marks) or ISSN number in the search content box, and click search to search.

5. The use of pubmed plug-ins: In order to directly display the impact factors of the magazine, the following two plug-ins can be achieved through pubmedy and "medical literature assistant". After installing it in the browser, you will be able to view IF, CITED, Citation and FullText (PDF) Direct PDF directly under the PubMed search interface.

For the pubmedy plug-in, the following 8 browsers are currently supported, and the plug-in can be dragged directly into the browser.
