METHODS: Medline (1966 to August 2005), MD Consult (1966 toAugust 2005), BIOSIS (1969 to August 2005), and EMBASE (1969to August 2005) databases were searched. Randomized and quasirandomizedstudies comparing GA and neuraxial blockfor elective THR were included in this analysis.

搜索 Medline （1996年－2005年8月）、 MD Consult （1966年－2005年9月）、 BIOSIS （1969年－2005年9月）和 EMBASE （1969年－2005年9月）的资料，分析其中包括随机或几乎随机的神经轴阻滞和全麻下行选择性全髋置换比较的数据。

A systematic literature search of PubMed, MEDLINE, BIOSIS, EMBASE, and Cochrane EBM databases during the period of 1990–2007 was made, objective being the randomised controlled trials in patients with AMI who underwent primary percutaneous coronary intervention and received intracoronary BMSC transfer, and were followed up for at least 3 months.

目前，冠脉内自体骨髓干细胞移植在AMI的临床应用仍存在较大争议。研究者检索了1990年至2007年间PubMed、MEDLINE、BIOSIS、EMBASE和Cochrane EBM等数据库收录的文献，根据以下标准纳入临床研究：以AMI症状出现24小时内接受PCI治疗者为研究对象；试验设计体现随机对照原则；移植细胞种类为非动员的自体骨髓干细胞；具有3个月以上的随访资料。

Bitemporal databases permit queries over two orthogonal time dimensions: valid time and transaction time.

时态数据库，允许在两个正交的查询时间方面：有效的时间和交易时间。

Firstly, working on the data model of temporal-relation, a bitemporal data model on object-relation is proposed in this paper, which may be implemented in current object-relational databases.

首先在现有时态关系数据模型基础上，提出了一种基于对象关系双时态数据模型，而这种数据模型适合于在现有数据库平台上实现；其次，在该模型框架内，讨论了时态对象关系模式与时态关系模式相互间的联系与转换，这也是由时态关系扩充到对象关系的基本要求：再次，分析了时态模型中时态变量复杂语义和相应绑定算法，这是时态数据库能够有效运行的基本课题
