癫痫诊治中医患同盟建立的实践与策略   总被引:2,自引:0,他引:2  
通过对肝硬化者行超声检测,预测食管静脉出血,结果显示,出血组门静脉及胃左静脉管径均增粗,但胃左静脉更明显,门静脉血流速减慢而胃左静脉增快;出血组胃左静脉均呈离肝血流,其分流指数明显增大。胃左静脉的管径及血流速与门静脉比较具有显著的变化,其分流指数和血流方向在预测出血方面具有更大的价值。  相似文献

由于诸多因素,使得一些高血压患者对治疗产生抵抗,或表现为难治性,其中有疾病因素、对治疗的依从性、其他药物的干扰和生活方式等。研究已经证明,有效地控制血压,使之达标,可以有效地降低重要靶器官受损的危险性。而规范、系统地控制血压、加强对抵抗性高血压的管理是保护靶器官的重要途径,同时需要进一步的研究证据的支持。  相似文献

植入前组织配型孕育“救星同胞”的伦理思考   总被引:1,自引:0,他引:1  
应用植入前遗传学诊断技术在胚胎植入母体子宫前,对人类白细胞组织相容性抗原配型检测,选择与现存患儿相同HLA配型的胚胎进行受孕,孕育一个组织配型相同的脐带血干细胞供者。在某种意义上说,该项技术的应用是创造人来获得移植组织,由此引发系列伦理争议。讨论孕育"救星同胞"这一医学实践内在需要的伦理规范。  相似文献

In the last 20 years many multi-objective linear programming (MOLP) methods with continuous variables have been developed. However, in many real-world applications discrete variables must be introduced. It is well known that MOLP problems with discrete variables can have special difficulties and so cannot be solved by simply combining discrete programming methods and multi-objective programming methods. The present paper is intended to review the existing literature on multi-objective combinatorial optimization (MOCO) problems. Various classical combinatorial problems are examined in a multi-criteria framework. Some conclusions are drawn and directions for future research are suggested.  相似文献

Respondents’ overt statements of relative importance rarely correspond to weights derived from a regression analysis of their decisions. This paper conjectures that differential effects of high-level goals on importance beliefs and choices can explain these discrepancies. It is argued that the goal to justify decisions influences importance beliefs more than choices whereas the goal to assess preferences accurately affects choices more than importance beliefs. It is also argued that differential effects of high-level goals on importance statements and choices vary as a function of whether decision-maker controls the information flow and the extent of prior knowledge and experiences with choice options. These predictions were tested within the context of a contraceptive decision-making task. Choices among contraceptives made the justification goal salient to subjects by requiring tradeoffs between attributes that are either considered rational or tempting in making such decisions (e.g., health risks vs. pleasure/convenience). As predicted, subjects assigned larger importance weights to rational attributes in their subjective evaluations than in their choices whereas the impact of tempting attributes was stronger for choices than for subjective importance evaluations. Moreover, these observed discrepancies between importance measures were reduced in favor of rational attributes when subjects controlled the information flow and could not access their prior experiences. Overall, the results suggest that, although tempting attributes affect choices, decision makers appear to be unwilling to acknowledge the impact of tempting attributes on their decisions in judging attribute importance.  相似文献

Self-schemata for threatening situations were examined in blood fearful and nonfearful individuals. In the context of 5 scenarios involving blood, injections, hospitals, or injury, participants listed events that they typically experience in these situations or events that occur when they witness another individual in these situations. Blood fearful and nonfearful individuals generally listed sequences of events corresponding to a similar macrostructure. However, blood fearful individuals included more negative emotional and physiological events than nonfearful individuals, and several of their sequences reflected higher levels of fear and lower levels of positive affect. These results suggest that the self-schemata of blood fearful individuals for situations involving harm or threat consist of both normal and maladaptive elements.  相似文献

Abstract

Mental representation has long been central to standard accounts of action and cognition generally, and in the context of sport. We argue for an enactive and embodied account that rejects the idea that representation is necessary for cognition, and posit instead that cognition arises, or is enacted, in certain types of interactions between organisms and their environment. More specifically, we argue that enactive theories explain some kinds of high-level cognition, those that underlie some of the best performances in sport and similar practices (dance, martial arts), better than representational accounts. Flow and mushin (mindfully fluid awareness) are explained enactively to this end. This results in a mutually beneficial analysis where enactivism offers theoretical and practical advantages as an explanation of high performance in sports, while the latter validates enactivism.  相似文献

The relationships of spirituality and religion to acute cardiovascular responses, physical symptoms of illness, stress and psychological mood were assessed in a community sample of adults. Nineteen men and 61 women participated in a betrayal interview, while their blood pressure and heart rate were monitored. Religious affiliation, frequency of attendance at worship and religiousness were associated with resting diastolic and mean arterial pressure. Spirituality, especially as assessed by the existential scale of the Spiritual Well-being Scale, was related to symptoms of illness, medication use, stress and negative mood states. Spirituality and involvement in organized religion may represent a means to increase the sense of purpose and meaning in life, which is related to greater resiliency and resistance to stress-related illness.  相似文献

The purpose of this study was to examine cerebral blood flow in the frontal cortex area during personality self‐rating tasks. Our two hypotheses were (1) cerebral blood flow varies based on personality rating condition and (2) cerebral blood flow varies based on the personality traits. This experiment measured cerebral blood flow under 3 personal computer rating conditions and 2 questionnaire conditions. Comparing the rating conditions, the results of the t‐test indicated that cerebral blood flow was higher in the questionnaire condition than it was in the personal computer condition. With respect to the Big Five, the result of the correlation coefficient, that is, cerebral blood flow during a personality rating task, changed according to the trait for agreeableness. The results of the analysis of the 5‐cluster on individual differences indicated that certain personality traits were related to the factors that increased or decreased cerebral blood flow. An analysis of variance indicated that openness to experience and Behavioural Activation System‐drive was significant given that participants with high intellectual curiosity were motivated in this experiment, thus, their cerebral blood flow may have increased. The significance of this experiment was that by employing certain performance measures we could examine differences in physical changes based on personality traits.  相似文献

The differences between meaningful and psychologically rewarding occupations were investigated. Fifty-two individuals from the United States and South Africa participated in the research, which was conducted using the Experience Sampling Method. Participants were cued at random, five times per day for 7?days. Each time when cued, they documented the types of occupations in which they were participating, associated mood, and perceived meaning of the occupations. Meaningful and psychologically rewarding occupations were similar: Both were physically stimulating and connected participants with other people. There were differences between U.S. and South African participants regarding perceived meaning of occupations and associated mood.  相似文献
