The topic is the author's heart sound. After reading the title, readers can know the purpose of the paper and have a general understanding of the main contents of the paper; Conforming to the pronunciation taste is exactly what readers are pursuing. I didn't necessarily want to read the full text. After reading the title, I immediately became interested in reading the full text. For example, the title "New Progress in Anticancer Drugs" shows that the article is a summary, and the author's intention is to introduce new methods and new achievements in anticancer drug research at home and abroad in order to promote its application. The majority of clinical, pharmacological, pharmaceutical workers and tumor patients suddenly became interested in reading the full text when they saw the title. If the title is changed to "Introduction of Several Anticancer Drugs", the purpose is unclear and the intention is implied. Everyone will think it is a commercial advertisement, not to mention patients, even professionals don't want to see it. How to reflect the purpose of the paper, that is, how to make the paper relevant, you may wish to choose the following methods. The article precedes the topic, based on the existing scientific and technological achievements, first writes a paper, and then draws up the topic according to the main pen of the paper. Or do a title first, then do a paper, imagine several different titles, and then compare them with each other according to the contents of the paper, and choose the appropriate and eye-catching one to use. Generally speaking, the former is mostly used to write papers such as retrospective analysis, clinical summary and case report, while the latter is mostly used to write papers such as prospective research, investigation report and summary lecture. Medical papers that embody the three elements of scientific and technological design, especially those with strong scientific research and high academic value, are indispensable for "research objects, therapeutic factors and observation indicators". A good title must also reflect these three elements in order to turn the stone into gold for the full text. An important reason for readers to decide whether to read the full text at first sight is to see whether the title reflects these three elements and what are their unique merits. For example, the topic "Effect of Riboflavin on Platelet Aggregation and Cardiac Function in Coronary Heart Disease", in which three elements are clear at a glance, and the therapeutic factor (application of Riboflavin) adopted by the research object (coronary heart disease) is novel and unique. Although this article is a basic research article, clinicians will not let it go easily. For example, if the topic is changed to "the application of Transflavin in coronary heart disease", even if there are research objects and treatment factors, it is not scientific enough because of the lack of observation indicators. Although this article is good, the reader will read it after reading the title, but it doesn't make much sense. The title of the paper should not only reflect the theme of the paper concisely, but also be different from other similar papers to avoid similarities. Therefore, we must adhere to the principle of "more words and less words". Some authors often like to use: ××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××× How many words is the length of the title appropriate? The standard is to accurately reflect the theme of the article. One more word is tedious, and one less word is incomplete. To cherish ink like gold, but also to lay the floor, the same thing is not good to say too much. For example, the topic "The Effect of Zinc Deficiency on Infants' Appetite" is short, comprehensive, concise and clear, and the author's intention is clear at a glance, which is easy to remember and quote. For example, the title "Comparative study of octreotide and pituitrin combined with phentolamine in the treatment of esophageal and gastric varices bleeding" is not complicated, and the expression of missing one word is unclear, which makes readers deeply impressed. In case the title is too long and there is a long list of qualifiers, if some words are deleted and the content is unclear, you can consider adding subtitles at this time; However, subheadings should be used sparingly and only when absolutely necessary. Pay attention to the basic expression of Chinese knowledge. In addition to the most basic requirement-sentence fluency, the title of scientific papers should pay special attention to accurate words, proper grammar, proper language habits and word order. For example, the topic "Discussion on the Law of Natural Environmental Factors of Esophageal Cancer" seems smooth at first glance, but there are many shortcomings in expressing knowledge in Chinese. Word order can be understood as the natural environmental factors of esophageal cancer; Obviously, this is a logical concept error. Natural environmental factors are the main body, the "cause" and the "fruit" of esophageal cancer. Only by adding the word "cause" to the topic at present can the logical concept be accurate. There are many natural environmental factors, involving a wide range, so it is impossible for the author to investigate and study every item; In fact, this article is an observation and study of natural factors such as living environment and cold climate. It is better to change the "natural environmental factors" in the title to "climate and living environment factors". It is understandable for scientific and technological workers to explore laws, clarify mechanisms and design models. If the natural environmental factors in dozens or even dozens of cases are raised to "regularity" or "mechanism", it seems to be exaggerated. The title not only stays for research, but also feels that the author is not modest enough; It is better to delete "legal discussion" and change it to "investigation" or "observation". Now it is customary to say "esophageal cancer" instead of "esophageal cancer" in medicine, just like saying "fever" is not standardized and rigorous. It is not surprising that various problems appear in commercial advertisements, but it is not advisable to appear in the titles of medical papers, so we should pay special attention to them. As we all know, computer retrieval technology is one of the fastest and most effective media means to disseminate scientific and technological information in the world today. There are a lot of medical papers. In a very short time, only through computer retrieval technology can we look up the literature we want to know, and only by mastering the keyword index can we retrieve the first-hand current information. Each topic has a thesaurus. After the topic is decided, be sure to check whether the subject words meet the requirements. If the title does not include the words (words) that may be used in indexing, or even not, then this proposition is a failure; Otherwise, the verification is successful. For example, the topic "Anesthesia and hemodynamic monitoring of orthotopic liver transplantation in pigs", in which "liver transplantation, anesthesia, hemodynamics and pigs" can be found in the thesaurus and can be used as a keyword index. After verification, this title is good. What important noun terms should be used in the title to include the words (words) that may be used in the index, which can be solved by "reduction to absurdity". The author can make the following assumptions; If you want to find papers related to your work in the literature index, under which headings should you look? These headings are important terms you should use. In addition, when abbreviations, codes and numbers are used in the title, it is also easy to make mistakes; But it is relatively easy to master these contents, so I won't go into details here.
