Most authors often encounter many difficulties when writing and publishing SCI papers, such as inadequate expression of ideas or meanings, frequent language problems, inadequate preparation for submission, and ignorance of online submission interface. 1. The experience of front-line medical workers engaged in scientific research and thesis writing tells us that insufficient expression of ideas or meanings is mostly due to insufficient reading of documents. The possibility of publishing an article is not because of positive results, but because it can provide academic guidance for other medical workers and solve academic problems that other studies have not solved. From the above, without a certain amount of literature reading, we can't understand the progress of the research, and we can't provide an academic orientation for this research. The reviewers of SCI journals don't look at whether the results of the papers are negative or positive. The most important thing is whether they have academic significance. 2. Language problems The authors of SCI papers in China will be rejected due to some language problems. Many authors turn to translation to translate Chinese papers into English. This is a reasonable way, but the key lies in how to choose a medical translator with reasonable price and guaranteed quality. When choosing SCI medical paper service institutions, we must comprehensively examine their strength, especially their basic qualifications and unsuccessful experience in publishing manuscripts. Senior editors know that when translating sci papers, we should not only focus on literal translation, but also modify and translate them according to the specific characteristics of SCI papers. Obviously, a service organization with no medical background or no publishing experience is totally incompetent for this job. 3. There is no preparation for submission. Usually, the materials to be prepared before submission include selecting the target journal, modifying the basic format of the paper, writing a cover letter, recommending reviewers, etc. These information sources are mainly obtained by logging into official journals and viewing corresponding columns. Among them, many authors regard writing a cover letter as a simple letter, but it is not. Authors with rich publishing experience regard the cover letter as a necessary method to show the research value of the article and promote the comment of the article (rather than directly rejecting it). In the cover letter, short sentences can comprehensively summarize the central idea of the paper and deepen the editor's understanding of the value of the article. 4. I don't understand the online submission interface. Most submission interfaces are progressive program interfaces. Any step is wrong or the information input format is incorrect, and finally you can't contribute. Therefore, you need to check the submission instructions first. In the process of publishing papers, the common problem is to select reviewers. This problem can be solved by selecting suitable reviewers according to the corresponding grades of journals and finding the names and eils of recommended reviewers. It must be noted that it is ultimately up to sci journals to decide whether to select reviewers recommended by authors.
