减少手术创伤始终是妇科肿瘤手术快速康复的决定性因素

减少手术创伤始终是快速康复的决定性因素,这一点在目前的加速康复外科研究尤其是复杂手术,如妇科肿瘤手术中尚未得到充分重视。尊重学习曲线、全面规划手术方案、总结失利经验、开展前瞻性研究是解决此问题的主要方案。本文着重讨论妇科肿瘤手术创伤对术后加速康复的影响及可能的改进措施。     

青海察汗森地区白钨矿成矿特征及找矿潜力

察汗森矿区位于青海省欧龙布鲁克陆块边缘,出露地层为古元古界达肯大板岩群地层,成矿地质构造条件优越。通过对该地区成矿地质特征、成矿构造环境、地球化学特征、矿石特征及矿化分布规律进行研究与分析,认为混合岩化热液与碳酸岩接触交代是成矿的主要原因,矿化与矽卡岩化关系密切。初步总结了该区成矿模式,认为该区具有形成与混合岩化有关的矽卡岩型白钨矿的有利条件,为该区下一步矿产勘查工作指明了方向。

从远景规划到概念规划

城市发展战略的研究和规划、从国外到国内,从上世纪末的远景规划到本世纪初的“概念规划”,一脉相承,并随着经济社会的发展和变革不断发展,概念规划是在竞争年代下一个战略研究的创新。城市规划应包括四个层面:城市研究、城市规划、城市设计、城市管理,而城市发展的战略研究,正是加强了城市研究,这种高层次的研究工作,对城市发展发挥了纲举目张的作用,它并不企图取代城市总体规划,而是更丰富了城市规划内容和完善城市规划的体系,对城市规划工作者也是一种知识更新的挑战。     

莫桑比克前寒武纪地质与成矿特征

莫桑比克作为全球重要的前寒武纪变质单元之一,是冈瓦纳古陆重要的组成部分。对其基础地质研究过程从19世纪初至今主要经历了4个阶段,本世纪初至今新理论和新方法的应用使得其基础地质研究得到飞跃发展。莫桑比克的前寒武纪地质单元可划分为津巴布韦-马尼卡克拉通基底、莫桑比克构造带及伊鲁米德构造带3个部分,其每部分又可进一步细分不同的构造单元(细化)。结合地质特征及矿产分布情况明确了莫桑比克的优势矿产资源为天然气、煤、钛、金、钽及石墨等矿种。莫桑比克可划分为北赞比西河成矿省、津巴布韦克拉通边界-巴鲁埃杂岩成矿省、乌南戈-利欣加成矿省、莫桑比克带-鲁伍马-赞比西成矿带省等四大成矿省和21个具有找矿前景的多金属成矿远景区。本文详细地划分了莫桑比克前寒武纪重要成矿区带并分析其成矿地质条件,结合近年来的矿产勘查工作认识,系统梳理了莫桑比克前寒武纪重要成矿区带的成矿条件和规律,重点总结了优势矿种的成矿特征,为莫桑比克矿业投资提供参考,并针对开展莫桑比克重要战略矿产的投资提供依据。     

A comprehensive meta-analysis on evidence of Mediterranean diet and cardiovascular disease: Are individual components equal?

Many studies have reported that higher adherence to Mediterranean diet may decrease cardiovascular disease (CVD) incidence and mortality. We performed a meta-analysis to explore the association in prospective studies and randomized control trials (RCTs) between Mediterranean diet adherence and CVD incidence and mortality. The PubMed database was searched up to June 2014. A total of 17 studies were extracted and 11 qualified for the quantitative analysis. Individuals in the highest quantile of adherence to the diet had lower incidence [relative risk (RR): 0.76, 95% confidence intervals (CI): 0.68, 0.83] and mortality (RR: 0.76, 95% CI: 0.68, 0.83) from CVD compared to those least adherent. A significant reduction of risk was found also for coronary heart disease (CHD) (RR: 0.72, 95% CI: 0.60, 0.86), myocardial infarction (MI) (RR: 0.67; 95% CI: 0.54, 0.83), and stroke (RR: 0.76; 95% CI: 0.60, 0.96) incidence. Pooled analyses of individual components of the diet revealed that the protective effects of the diet appear to be most attributable to olive oil, fruits, vegetables, and legumes. An average reduced risk of 40% for the aforementioned outcomes has been retrieved when pooling results of RCTs. A Mediterranean dietary pattern is associated with lower risks of CVD incidence and mortality, including CHD and MI. The relative effects of specific food groups should be further investigated.

Special issue editorial: Prospective memory in 2010.

In order to raise awareness of prospective memory, this special issue features contemporary research on the topic. The occasion for a special issue was the 3rd International Conference on Prospective Memory, which was held in July 2010 in Vancouver, and which brought together nearly 100 scientists from 16 different countries. The conference showcased new research, as well as a host of breakthrough discoveries and methodological insights, and it served to underscore why prospective memory deserves and is likely to receive more prominence in the future. As has been and continues to be the case for retrospective memory, however, most prospective memory research seems to be focused on its episodic component, on questions such as the following: Once a plan has been made, and my attention has turned elsewhere, how does that plan come back to mind at the appropriate time or context? Why do plans sometimes to pop into mind all of the time, including when our attention ought to be focused elsewhere? Why does an obvious cue, such as the mailbox in my way, sometimes fail to reactivate a previous intention? What strategies, if any, are available for improving prospective memory? The articles in this issue address these and related questions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

辽东清原金富集带含金韧性剪切带远景评价

Characterizing multiple memory deficits and their relation to everyday functioning in individuals with mild cognitive impairment.

The authors evaluated multiple memory processes and explored their contributions to everyday functional limitations in persons with mild cognitive impairment (MCI). Participants included individuals with amnestic MCI, nonamnestic MCI, and healthy older adults. As expected, the amnestic MCI group performed more poorly than the control and nonamnestic MCI groups on a content memory measure. Both MCI groups, however, performed more poorly than controls on the noncontent memory measures of prospective memory, temporal order memory, and source memory. Informants also reported that the MCI groups were experiencing greater difficulty than controls completing instrumental activities of daily living (IADLs). Noncontent memory measures were found to make an independent contribution to IADL performances over and above that of content memory. These findings demonstrate that impairments in memory beyond the traditionally assessed content memory are present in individuals with amnestic MCI and with nonamnestic MCI. The results further show that these noncontent memory processes, which have been linked with executive functioning, play a role in supporting IADLs.
