目的：短暂性脑缺血发作（TIA）是常见和重要的卒中先兆。其处理方法多样，大多数发表的指南在近年来均未被更新。我们试图制定一个全面的、无偏倚的、循证的TIA处理指南。方法：根据一种客观标准（可以预测在该研究领域中执业医师对专家提名的文献测量学方法）挑选出15名专家组成员。通过系统回顾检索到过去发表的指南，由专家对其中的推荐意见的质量进行独立评价。选择出质量最高的推荐意见，然后让专家组采用改良Delphi法通过多次问卷调查的方式进行修订，从而对新的修改达成共识。给专家们提供近期临床研究的系统评价，要求专家根据新的证据判断措辞修改的合理性并且根据证据等级和质量对最终的推荐意见进行评定。不允许专家在预期有可能存在任何利益冲突的专题方面提出推荐意见。结果：通过系统回顾检索到257个指南，其中有13篇文献包括的137条推荐意见符合所有纳入标准。需要6次重复的问卷调查对53条最终推荐意见的措辞达成共识。最终的推荐意见涉及TIA的初步处理、评价、内科治疗、外科治疗和危险因素控制。结论：对TIA患者医疗诊治的最终推荐意见强调了紧急评价和治疗的重要性。这种用于制定本指南的新方法是可行的，考虑到了快速更新并能减少偏倚。

We introduce the Dirac equation in four-dimens.onal gravity which is.a generally covariant form. We choos. the s.itable variable and s.lve the corres.onding equation. To s.lve s.ch equation and to obtain the corres.onding bis.inor, we employ the factorization method which introduces.the as.ociated Laguerre polynomial. The as.o- ciated Laguerre polynomials.help us.to write the Dirac equation of four-dimens.onal gravity in the form of the s.ape invariance equation. Thus.we write the s.ape invariance condition with res.ect to the s.condary quantum number. Finally, we obtain the s.inor wave function and achieve the corres.onding s.ability of condition for the four-dimens.onal gravity s.s.em.

背景卒中是一种主要的残疾和死亡原因。脑卒巾联盟提议，建立初级卒中中心（primary s.roke center，Ps.）和综合性卒中中心（comprehens.ve s.roke center，cs.）以分别为需要基本或高级下预的卒中患者提供适当的医疗服务。从2003年开始，美国医疗卫生机构认证联合委员会和各州已指定了一些Ps.，目前正在考虑Cs.的指定工作。为了推进该过程，我们提出了一套Cs.应追踪监测医疗质量并促进质量改进的标准和相关数据。方法和结果我们分析了现有指南、综述和其他文献，以识别区分Cs.与Ps.的主要特征；起草了一套标准和相关数据元素，以评价这些卒中医疗方面的关键部分；然后通过反复修改达成共识。我们提出的这套标准和相关数据元素，涵盖了Cs.内缺血性脯血管病、非外伤性蛛网膜下腔出血和腩出血患者专、№医疗的主要方面。结论我们提出这套标准，旨在为Cs.的标准化数据采集提供一个框架，以促进当地医疗质量改进，并允许对来自不同Cs.的数据进行合并分析。这将有助于将来Cs.国家执行标准的制定。

Previous.s.udies.s.gges.ed that pigs.prefer lower environmental temperatures.during nighttime compared to daytime. s. reducing nocturnal temperature in nurs.ry barns.may not jeopardize performance or welfare of pigs. but can s.ve energy for heating the barn. A s.udy was.conducted to inves.igate growth performance and behavioral res.ons. of nurs.ry pigs.to reduced nocturnal temperature. This.s.udy was.conducted in four replicates. each utilizing 270 newly weaned pigs.and las.ing for 5 wk. Temperature s.tpoint in the control room （CON） was.s.arted at 30℃ and decreas.d by 2℃ per week. In the treatment room （RNT）, temperature s.tpoint was.maintained s.me as.in CON between 7：00 h and 19：00 h, and reduced by 8~C between 19：00 h and 7：00 h s.arting from d 5. Growth performance （15 pens.room, 9 pigs.pen, BW=（6.3±0.61） kg） was.monitored for 5 wk, and behaviors.in 6 pens.in each room were video-recorded for 24 h 3 d after being expos.d to the experimental temperature. Ins.antaneous.s.an s.mpling was.performed to determine time budgets.for s.anding, s.tting, eating, drinking, belly nos.ng, three pos.ures.of lying, and huddling. Two focal pigs.were continuous.y viewed to record duration and occurrence of eating and drinking. Reduced nocturnal temperature did not affect the growth performance of the pigs. time s.ent s.anding, s.tting, total lying and eating or duration and frequencies.of eating and drinking （all P〉0.10）.

In metropolitan regions. the change in the s.rength of "flows. between a core city and s.rrounding cities.re-flects.the range of the core city's.influence, while the gravity between core city and other cities.reflects.the s.rength of potential relation between them. This.article firs.ly attempts.to delimit the boundary of metropolitan regions.with the two dimens.ons.meas.re combining "flows. and gravitation. The former is.meas.red through the flow of people be-tween the core city and s.rrounding cities. and the latter is.meas.red through both population and gros. domes.ic products.(GDP) of the core city and s.rrounding cities. The hierarchy of the cities.within a metropolitan region is.clas.ified in order to emphas.ze the roles.of the cities.belonging to the metropolitan regions. different from the general way through population s.ale and adminis.rative level, and is.typical in China. This.paper us.s.the s.anghai metropolitan region as.a res.arch cas., determining boundary of this.metropolitan region clearly and clas.ifying hierarchy of the cities.within the region. The final res.lts.are s.gnificantly different to previous.work, even overthrowing the traditional s.s.em of urban hierarchy partly. It is.helpful to highlight the function of cities.in organizing the regional economy, the level s.ructure of metropolitan regions. and each city's.relative importance in a metropolitan region, which can be taken as.s.ientific bas.s.for planning integrated regions.or urban s.s.ems.
