OSAHS在2型糖尿病发病中的作用与对策

阻塞性睡眠呼吸暂停综合征（obstructive sleep apnea hypopnea syndrome,OSAHS）是一种常见的睡眠呼吸紊乱性疾病,以睡眠时反复发作的上气道部分或完全阻塞为特征。近年发现OSAHS与2型糖尿病之间有着明显的相关性,二者均为心血管疾病的高危因素,合并存在能够严重影响生命质量与预期寿命...     

体外循环所致炎性肺损伤机制及保护进展

肺损伤是体外循环心内直视手术的主要并发症之一。肺损伤的机制十分复杂,主要是全身炎性反应和缺血/再灌注损伤所致。肺保护的方法多种多样,其目的是降低全身炎性反应,减轻或避免缺血/再灌注损伤。本文探讨体外循环肺损伤的机制和保护进展。     

影响患者医疗知情权实现的细节因素分析

在医院细节文化的语境下,通过抽样问卷调查及结构式访谈法,提出在口语、书面语的医院方式文化中,影响患者医疗知情权实现的细节因素及其存在问题,并结合相关制度规定,分析存在问题的原因,进而寻找保障患者医疗知情权实现途径及对策,以期构建和谐医患关系。     

The effects of training on caregiver implementation of incidental teaching

A brief training package consisting of modeling, rehearsal, and feedback was evaluated to train caregivers to use incidental teaching to teach 3 children with autism to request an item or activity. The training package improved correct implementation of the incidental teaching procedure by caregivers. In addition, probes indicated that caregivers could apply these skills to teach the child an additional skill.     

Spoon-to-cup fading as treatment for cup drinking in a child with intestinal failure

We treated a child with intestinal failure who consumed solids on a spoon but not liquids from a cup. We used spoon-to-cup fading, which consisted of taping a spoon to a cup and then gradually moving the bowl of the spoon closer to the edge of the cup. Spoon-to-cup fading was effective for increasing consumption of liquids from a cup.     

On using Vernier acuity to assess magnocellular sensitivity

A recent study [Keri, S., & Benedek, G. (2009). Visual pathway deficit in female fragile × premutation carriers: A potential endophenotype. Brain and Cognition, 69, 291–295] has found Vernier acuity deficiencies together with contrast sensitivity defects consistent with a magnocellular deficit in female fragile × premutation carriers. This may appear to support the notion that Vernier acuity may serve as a test of magnocellular sensitivity. However, Vernier acuity deficiencies have been reported in other conditions (e.g., schizophrenia, amblyopia and cortical visual impairment) where there is little evidence for magnocellular deficits. The observation that Vernier acuity deficiencies can occur without magnocellular deficits indicates that Vernier acuity is not a reliable test of magnocellular sensitivity.     

Right‐wing authoritarianism,Big Five and perceived threat to safety

Using structural equations modelling, we performed a secondary analysis of the data collected by the Italian Observatory of the North West (Italian national sample, N = 976) to investigate the direct, mediated and moderated relations connecting the Big Five personality factors and perceived personal and societal threat to safety with right‐wing authoritarianism (RWA). Openness, Conscientiousness and perceived societal threat to safety exerted additive effects on RWA; the relation between Openness and RWA was partially mediated by societal threat to safety and that between societal threat to safety and RWA was moderated by Openness. Limitations and possible developments of this research are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

胃黏膜内pH在多脏器功能障碍综合征监测中的应用进展

组织器官微循环灌注障碍是MODS发生的重要机制,胃肠道是机体最早发生缺血的器官。胃PHi能敏感反映MODS发生过程中胃肠黏膜缺氧情况,对MODS具有预警作用。目前测定PHi方法分盐水张力计法和连续气态张力计法,效果较可靠。本文通过大量查阅文献,结合临床经验,较系统地阐述了pHi在MODS监测中的意义、原理、方法、安全性及应用前景,为及早采取措施,防治MODS提供理论依据和临床参考。     

急性冠脉综合征患者合并抑郁障碍对生存质量的影响

为了了解急性冠脉综合征(ACS)患者合并抑郁障碍的现状及其对生存质量(QOL)的影响,对104名ACS患者应用一般情况调查表、HAD(d)、SF-36进行调查。结果显示31.73%的ACS患者合并抑郁障碍;ACS伴抑郁障碍SF-36各因子分均低于不伴抑郁障碍;HAD(d)总分与SF-36各因子分均呈负相关。因此ACS患者是抑郁障碍的易感人群,且抑郁障碍可降低ACS患者的QOL。     

不同机械通气模式下吸痰对ARDS患者肺通气及顺应性的影响

为探讨不同机械通气模式下吸痰对ARDS患者肺通气及顺应性的影响。选择20例ARDS机械通气患者,随机分为A/C组与SIMV组;分别给予开放式吸痰,记录吸痰前后肺通气指标及呼吸系统顺应性指标的变化。结果吸痰后各时间点呼吸频率均显著增加(P0.01);潮气量、分钟通气量在0s显著降低,吸痰后15s、1min显著增加(P0.01);两通气模式比较SIMV组呼吸频率、分钟通气量增加显著(P0.01)。吸痰前后动静态顺应性、动态P-V曲线斜率差异不显著(P0.05),通气模式之间亦无统计学差异。提示开放式吸痰引起呼吸频率显著增加,潮气量及分钟通气量先是下降然后显著增加;SIMV模式呼吸频率、通气量增加较为显著。不同通气模式下吸痰对呼吸系统顺应性影响不显著。
