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。     

A Multinomial Model of Event-Based Prospective Memory.

Prospective memory is remembering to perform an action in the future. The authors introduce the 1st formal model of event-based prospective memory, namely, a multinomial model that includes 2 separate parameters related to prospective memory processes. The 1st measures preparatory attentional processes, and the 2nd measures retrospective memory processes. The model was validated in 4 experiments. Manipulations of instructions to place importance on either the prospective memory task or the background task (Experiments 1 and 2) and manipulations of distinctiveness of prospective memory targets (Experiment 2) had expected effects on model parameters, as did a manipulation of the difficulty of prospective memory target encoding (Experiments 3 and 4). An alternative model was also evaluated. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

新疆东昆仑地区金矿成矿地质条件及找矿方向初探

东昆仑地区是昆仑巨型成矿带中２个重要的成矿区之一，从大地构造背景、沉积建造、岩浆活动等成矿地质条件的分析入手，对东昆仑地区的求勉雷克成矿远景区、鸭子泉成矿远景区、库木巴彦成矿远景区和石雪尖成矿远景区的金矿成矿条件进行了初步的探讨，指出了找矿方向。     

巴彦浩特盆地演化特征与含油气性评价

古、中生代盆地发育受基底断裂控制,呈现由南向北迁移的特征。除自生自储类型以外,油气运移聚集主要与多期区域性不整合面有关。根据不同地区的改造特点、强度和保存条件等方面的差异,将盆地成藏单元类型划分叠合—再生型、改造—保存型、改造—再生型和改造—破坏型,其成藏条件和油气勘探远景依次变差。     

纳米技术的杰作——纳米吸波材料

纳米吸波材料作为一种有着巨大发展前景的高技术功能材料，成为未来吸波材料的发展方向。本文从介绍纳米吸波材料的结构特征和吸波特点出发，说明了纳米吸波材料的独特吸波性能，同时对几种蚋米吸波材料进行了介绍。通过对现阶段国内外纳米吸波材料研究进展的评速与讨论，总结出其宽频化、复合化、低维化和智能化的未来发展趋势。     

前瞻记忆与紧张度的关系研究

紧张状态下的前瞻记忆表现是应急反应研究的一个新视角。运用自行研制的实验材料，在前瞻记忆的实验法范式下，对不同呈现速度(即紧张程度)和分心条件下，前瞻记忆的绩效进行了比较。结果发现前瞻记忆的绩效随紧张程度增大而显著降低；快速比慢速受分心影响小，并且这种趋势接近显著水平。此研究对于探讨前瞻记忆在紧急突发事件中的应用，具有重要的借鉴意义。     

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.     

甘肃夏周贡玛金矿土壤地球化学特征及找矿前景

夏周贡玛金矿位于西秦岭褶皱带北部之北中秦岭陆表海盆内,属夏河—合作金、铜成矿带。通过对该矿区地球化学特征进行总结研究,认为金异常对金矿化蚀变带空间分布具有指示意义,为矿区的后续找矿工作提供了依据。     

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。     

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。
