24 EMBASE CD Description:
Over 6 million abstracts and citations from 1980 to the present- over 4,000 biomedical journals are screened from 70 countries. Monthly updates will add approximately 34,000 new records. Important drug information not covered in other major biomedical databases EMTREE Thesaurus incorporating a user-friendly combination of EMTREE descriptors and medical MeSH terms

25 EMBASE分类系统 EMTREE 1988年开始使用 EMCLAS 1974-1988年 EMBASE的分类系统， EMTAGS
全面的索引分类体系，1998年停用

26 EM CLASSIFICATION SYSTEM
EC(EMCLAS) EMBASE最早的主题分类体系，它的一级分类号用来标引记录，用户可以用EC字段用来检索相应记录。 药物EC 药物EC标题（37）1990年停用，表现为数据库的EL字段中的药物11位数字。

27 EM CLASSIFICATION SYSTEM
EMCLAS - Section Numbers and Headings 1 Anatomy, anthropology, embryology and histology 2 Physiology 3 Endocrinology … 37 Drug EMCLAS Adverse reactions titles 39 Pharmacy … 52 Toxicology 151 Mycobacterial diseases ( ) 完整列表可见EMBASE帮助系统

28 EM CLASSIFICATION SYSTEM
EMTREE 受控词汇 等级排列 树状结构 （15方面 115分支 再次细化 各类的范围注释） Anatomical concepts (facet A) Physical diseases, disorders and abnormalities (facet C) Chemicals and drugs (facet D) 字顺索引(上下位词，相互参照）（手工版本）

29 EMTREE 45,000药物医学术语 10,000个代码 190,000同义词包括各种药物名称的变化形式和NLM的MeSH主题词

30 EMTREE EMTREE Stomach bleeding Stomach hemorrhage(首选词）

31 EMTREE EMTREE中检索时，系统将同时检索: Major Medical Descriptors (DEM), Minor Medical Descriptors (DER), Major Drug Descriptors (DRM), and Minor Drug Descriptors (DRR)字段（2000年以后）。

32 EMTREE EMTREE取词规则 *自然词语序 e.g. acute granulocytic leukemia (急性粒细胞性白血病 not leukemia, acute granulocytic) *单数名词形式 e.g. stomach tumor (not gastric tumors) *美式写法优先于英式写法 e.g. fetus (not foetus) *少数的缩写词 e.g. nuclear magnetic resonance (“nmr” is a synonym) *希腊字母拼出 e.g. alpha adrenergic receptor *元标点，无连字符，省略号，逗号，化学物质除外。 e.g. down syndrome; 4 ethyl 2,5 dimethoxyamphetamine (二甲苯异丙胺）[连字符用于精确检索] *可使用专深词汇 e.g. acute lymphocytic leukemia (as well as the broader term "leukemia")

33 EMTREE EMTREE的作用 查找扩展词，防止漏检 浏览扩展词的下位词 查找标引首选词 通过term information确定检索词

34 EMTREE 示例： Hay fever(花粉热) respiratory tract allergy
allergic pneumonitis allergic rhinitis asthma hay fever house dust allergy nose allergy pollen allergy

35 EMTREE EMTREE药物索引 paracetamol (首选词）
EMTREE包括根据世界卫生组织国际命名标准而确定的药物及化学物质首选名称，其中，药物一般名称包括，实验室代码，商品名称，各种拼写，外来名称，化学复合物名称及MESH主题词 propranolol（DOCITON和INDERAL) paracetamol (首选词） acetaminophen and 4 acetamidophenol 数据库中DRM和DRR字段包括标记这些首选药物和化学物质名称，商品名称在TN字段

36 EMTREE EMTREE - Disease Link and Drug Link Terms
Disease link terms and drug link terms are controlled terms frequently used with a medical or drug index term to indicate precise associations. They have been used in EMBASE since Search for these associations by using a hyphen between the index term and the link term or as independent terms. For example, the search cardiovascular-surgery in su retrieves records that are about surgical aspects of cardiovascular.

37 EMTREE 14个疾病关联词 Disease Link Terms
Complication Congenital disorder Diagnosis Disease Management Drug resistance (began 1996) Drug therapy Etiology 14个疾病关联词 Epidemiology Prevention Radiotherapy Rehabilitation Side effect Surgery Therapy

38 EMTREE Disease Link Terms 示例： Parkinson's disease+surgery 1988以前：
parkinson disease and surgery（98） 现在： Parkinson- disease/surgery(62)

39 EMTREE Drug Link Terms 17个主药物关联词
Adverse drug reaction Clinical trial Drug administration Drug analysis Drug combination Drug comparison Drug concentration Drug development Drug dose Drug interaction Drug therapy Drug toxicity Endogenous compound Pharmaceutics Pharmacoeconomics Pharmacokinetics Pharmacology 47个分支药物关联词 Buccal drug administration Epidural drug administration Inhalational drug administration……
