11 NCBI ( National Center for Biotechnology Information )  General Introduction Established on 1988, as a division of the National Library of Medicine (NLM) at the National Institutes of Health (NIH).

12 NCBI ( National Center for Biotechnology Information ) General Introduction Conducts research on fundamental biomedical problems at the molecular level using mathematical and computational methods Maintains collaborations with several NIH institutes, academia, industry, and other governmental agencies Fosters scientific communication by sponsoring meetings, workshops, and lecture series Supports training on basic and applied research in computational biology for postdoctoral fellows through the NIH Intramural Research Program

13 NCBI ( National Center for Biotechnology Information ) General Introduction Engages members of the international scientific community in informatics research and training through the Scientific Visitors Program Develops, distributes, supports, and coordinates access to a variety of databases and software for the scientific and medical communities Develops and promotes standards for databases, data deposition and exchange, and biological nomenclature

14 NCBI ( National Center for Biotechnology Information ) Entrez ( Cross-Database Search System ) It is a powerful federated search engine, or web portal that allows users to search many discrete health sciences databases at NCBI website.

97 Jadad Scale 97 Jadad AR, Moore RA, Carrol D, et al. Assessing the quality of reports of randomized clinical trials: is blinding necessary [J] Control Clin Trials, 1996, 17:1–12.

98 Jadad Scale Grade  Full Mark: 5  High Mark : ≥3  Low Mark: < 2 : easy, abroad : lack of allocation concealment

99 Jadad + Schulz  Adequate  Inadequate  Unclear

100 e.g. Title Randomized clinical trial of intravenous soybean oil ( 豆油 )alone versus soybean oil plus fish oil emulsion ( 乳剂 )after gastrointestinal cancer surgery. Jiang ZM, Wilmore DW, Wang XR, et al. Br J Surg. 2010, 97(6):

101 e.g. 101 Reference: Jiang ZM, Wilmore DW, Wang XR, et al. Randomized clinical trial of intravenous soybean oil alone versus soybean oil plus fish oil emulsion after gastrointestinal cancer surgery. Br J Surg. 2010, 97(6): Material & Method R DB

102 Follow-up

103 e.g. Jadad – 随机: 2 分(文中描述了随机序列产生方法且方法恰当) – 双盲: 2 分(文中描述了实施双盲的方法且盲法恰当) – 退出与失访: 1 分(文中对退出的例数和理由进行了详细 描述,无失访) 此文总得分为 5 分,属高质量研究 103

104 e.g. 104 Reference: Jiang ZM, Wilmore DW, Wang XR, et al. Randomized clinical trial of intravenous soybean oil alone versus soybean oil plus fish oil emulsion after gastrointestinal cancer surgery. Br J Surg. 2010, 97(6): Material & Method

105 e.g. Schulz 隐蔽分组 – 此文中产生随机序列者(统计室)和决定分配序别 者(配药护士)均未参与纳入患者的工作,也未参 与研究过程以及结果的测量和分析, 此文中隐蔽分组为充分( Adequate ) 105
