中文摘要:
      目的:阐述信息检索在医学科研选题中的重要作用,探讨医学科研选题3个阶段应遵循的原则和方法。方法:以一个宽泛的研究主题(生物碱与戒毒)为例,描述如何通过查全、查准的方法逐步缩小检索范围,提出假设并进行验证。结果:遵循上述原则和方法,可以全面获得生物碱与戒毒的相关研究背景,准确筛选出“辣椒辣素用于海洛因依赖戒断”的研究课题并进行验证。结论:通过全面、准确的文献检索可以有效地选题,通过查阅相关文献和利用非相关文献知识发现方法可以对所提出的假设进行验证,从而实现科学选题。
英文摘要:
      Objective To explain the important role of information retrieval and study the recall, precision and verification principles and methods in selection of medical research topics. Methods How to gradually narrow down the literature retrieval scope with the recall and precision methods was described with a relatively broad research topic (alkaloids and abstinence from poisons) as an example. A hypothesis was proposed and verified.Results The recall, precision and verification principles and methods could comprehensively detect the research background related with "alkaloids and abstinence from poisons", accurately screen and verify the research topic on "capsaicin used in heroin-dependent abstinence from poisons".Conclusion Comprehensive and accurate literature retrieval can effectively help to select the research topics, reading the relevant literature and use of the non-relevant literature knowledge discovery method can verify the hypothesis, which can thus help the scientific selection of research topics.
