发现幽门螺杆菌(Helicobacter pylori,以下简称Hp)导致慢性胃炎和消化性溃疡,是沃伦和马歇尔获得2005年诺贝尔医学奖的原因.他们在1982年得出的这一假说,违反了关于这一类慢性病传统的发病机制理念.可能因为这一理念的反传统性,其假说被世界同行基本接受大概经历了20年时间.值得强调的是,对HP的观察、分离、培养、鉴定和人体试验,以及它与疾病相关的诊断、治疗、临床流行病学等研究,应用的都是传统的医学技术.从而表明,即使到了20世纪80年代,传统技术仍能导致诺贝尔奖级科研成果的出现. 相似文献

The goal of this study was to examine stress-ameliorating effects of religiosity, spirituality, and healthy lifestyle behaviors
on the stressful relationship of chronic illness and the subjective physical well-being of 221 older adults. We also investigated
whether the intervening variables functioned as coping behaviors and orientations or as adaptations in late life. Guided by
the stress paradigm, path analysis was used to assess these relationships in a stress suppressor model and a distress deterrent
model. No suppressor effects were found; however a number of distress deterrent relationships were detected. Spirituality,
physical activities, and healthy diet all contributed to higher subjective physical well-being, as counter-balancing effects,
in the distress deterrent model. The findings have implications for future research on the role of spirituality, religiosity
and lifestyle behaviors on the well-being of chronically ill older adults. Findings also support the need for studying different
dimensions of religiosity and spirituality in an effort to understand coping versus adaptation in behaviors and orientations.

Simple motor reaction times (right-handed) to tape-recorded consonant-vowel syllables were obtained from 12 subjects under two conditions of monotic stimulation: “expected” presentation (subject informed as to ear of presentation) and “random” presentation (ear of presentation varied randomly). Significantly faster left ear reaction times were obtained in the “expected” condition. The rank order of subjects' standard dichotic listening task scores correlated negatively with reaction time ear differences in the “expected” presentation condition. Results are discussed in terms of existing theories of response lateralization in simple reaction time tasks, and an expanded hypothesis is offered. Specifically, it is suggested that two or more distinct but potentially overlapping mechanisms may be responsible for observed asymmetries in monotic auditory perception. Both an attentional or lateralized motor response bias and an inherent lateralization of function may operate side by side, differentially activated by task demands, mode of stimulus presentation, and nature of stimuli. 相似文献

This study examined the interaction between preferred modes of information processing (visual and verbal) and two cognitively-based anxiety-reduction techniques. One technique was based on the use of images as a coping strategy while the other employed a self-instructional approach. Thirty-six subjects reporting high levels of dental fear were assigned to one of three groups (two types of treatment and a no-treatment control). One-half of the subjects in each group had been identified as preferring the visual mode of information processing while for the other half the verbal mode was preferred. After treatment, subjects viewed an anxiety-inducing videotape depicting a visit to the dentist. Results indicated that, while both treatments were significantly effective in reducing self-reports of discomfort while viewing the videotape, there was no significant interaction between the type of treatment and preferred cognitive mode. The results were interpreted as indicating that treatment may override individual cognitive styles. Furthermore, the data suggested that the normal individual has the ability to adapt to divergent and non-preferred forms of information processing. 相似文献

研究试图探讨基于不同性质的调节定向(特质性调节定向和情境性调节定向)而达成的匹配所导致的效应是否一致。实验一、二均采用2(调节定向:促进、防御)×2(信息框架:积极、消极)被试间设计, 分别考察了两种匹配对信息说服效果(包括信息价值评价、情绪强度、行为意向3项指标)的影响。MANOVA检验表明, 实验一中信息价值评价、情绪强度2项指标上的交互作用显著, 实验二中信息价值评价、情绪强度和行为意向3项指标上的交互作用显著; 这表明, 基于两种不同性质的调节定向所达成的匹配在对信息价值评价和情绪强度的影响上具有一致的效应, 但在对行为意向的影响上具有不一致的效应。这一结果对于理解两种不同性质的调节定向之间的差异以及基于两者而达成的两种调节匹配之间的差异具有较为重要的意义。 相似文献

通过回顾国内外相关文献,从研究的意义、现状及研究的难点等方面综述慢性病患者及其配偶的二元应对纵向研究进展。结果显示夫妻的二元应对在不同疾病中随着时间推移呈不同的发展趋势;患者和配偶的二元应对方式及应对一致性对双方远期心理健康、关系质量等有重要的预测作用,且可能存在角色、性别、应对方式的差异。国内目前在该方面的研究较少,可借鉴国外研究方法,探究不同疾病背景下夫妻二元应对的发展及其对心理社会适应的预测作用,为制定有针对性的二元干预措施提供指导。

Structural equation modeling was used to examine the relationships between selected psychological variables and pain perceptions in 103 individuals experiencing chronic pain following traumatic spinal cord injury (SCI). Previous studies have suggested strong relationships between psychological variables and chronic SCI pain, but further delineation of such relationships is needed in order ultimately to develop more effective pain management strategies for individuals afflicted with such pain. Anger was found to be significantly related to perceptions of pain (p < .05), but neither guilt nor anger suppression was significantly associated with perceived pain. Internal health locus of control was associated with decreased pain perceptions (p < .05), but there was no significant relationship between internal health locus of control and anger. Punishing responses from significant others to pain complaints were related to feelings of guilt (p < .05) and perceived pain (p < .05), but this relationship was not mediated by guilt. 相似文献
