A new generation of intelligent systems is growing up in the community of Artificial Intelligence in Medicine. The main goal
of these systems is the representation and use of real theory of diseases, as they are represented in medical textbooks or
in scientific articles, rather than the heuristic shortcuts of human experts. In this paper, we will argue that the difficulties
in the integration of basic science and clinical knowledge in intelligent systems arise from ontological differences between
these kinds of knowledge and that the solution can be found in their dynamic integration during the reasoning process. In
order to illustrate this point, we will first describe an epistemological analysis of the interplay between basic science
knowledge and clinical knowledge, and then we will provide the example of a computational architecture implementing this view.

The present study was undertaken to investigate the effects of modulation of the (NMDA) receptor on learning and memory. Thus, the performance of rats treated with d-cycloserine, a partial agonist at the glycine recognition site of the NMDA receptor complex, and MK-801, a noncompetitive NMDA receptor antagonist, either alone or concurrently were assessed in radial arm maze and water maze tasks. Administration of MK-801 (0.1 mg/kg, i.p.) impaired acquisition in the water maze (increased escape latency and distance) and working memory in the radial arm maze (increased re-entries) in rats. Moreover, in the radial arm maze, MK-801 disrupted locomotion (increased latencies and decreased arm entries per minute) and impaired the acquisition of reference memory (increased number of errors) performance of rats. d-Cycloserine (0.03, 0.3, 1.0, 3.0, 10 mg/kg, i.p.) had no effects on acquisition or memory performance of control or MK-801-treated rats in either of these tasks. However, d-cycloserine (0.03, 0.3, 3.0 mg/kg) reversed the MK-801-induced disruption in locomotion. Furthermore, 3.0 mg/kg d-cycloserine increased behavioral activity and also decreased the time needed to complete the task in control animals. To conclude, our results suggest that the consequences of NMDA receptor modulation on learning and memory processes and sensorimotor functions may be functionally different or have distinct anatomical locations. 相似文献

- ? The purpose of this paper is to contribute to the debate on issues related to the reliability and validity of measurement of challenging behaviour (behavioural difficulties) in learning disability. A number of practical, theoretical and methodological issues are discussed that have significance for the nurse both as practitioner and/or researcher in learning disability. These issues are equally important to both provider and purchaser of health care in order that resources can be most effectively targeted.
- ? The term ‘challenging behaviour’ would appear to be used both in literature and research synonymously with behavioural difficulties, this has implications for nurses in both their clinical practice and/or research. The author concludes by identifying a need to replace the term challenging behaviour, with ‘behavioural difficulties’. It is argued that such a term is much more explicit in meaning and amenable to operational definition, thus enabling empirical study. Such a proposal will not be accepted by all as justifiable; this is because some might argue that adopting the term behavioural difficulties may be a retrograde step that perpetuates negative imagery and inappropriate labelling of people with a learning disability.

Rats were reared from weaning (21 days of age) either in isolation or in social groups of five for 30 days and were then tested for spontaneous locomotor activity and 7 days later for 5-hydroxytryptamine (5-HT) agonist-induced behaviour. Isolation-reared animals displayed locomotor hyperactivity when placed in a novel environment. 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) (2 mg/kg IP) and 8-hydroxy-2-(di-n-propyl-amino) tetralin (8-OH-DPAT) (0.32 mg/kg SC) elicited various components of the 5-HT behavioural syndrome in both groups of animals, with forepaw treading and flat body posture being significantly more pronounced in isolation-reared animals. 1-(2,5-Dimethoxy-4-iodophenyl)-2-aminopropane (DOI) (2.5 mg/kg IP), a 5-HT2 selective agonist, produced a significantly greater number of back muscle contractions in isolation-reared animals but there was no difference between the two groups in the number of wet-dog shakes produced. Forepaw treading and flat body posture are thought to be mediated by 5-HT1A receptor activation, and stimulation of this receptor by either 5-MeODMT or 8-OH-DPAT produced greater responding in isolation-reared rats, suggesting supersensitivity of the post-synaptic 5-HT1A receptor. Wet-dog shakes are thought to be mediated by 5-HT2 and other (none-5-HT) receptors while back muscle contractions have been shown to be mediated by 5-HT2 receptors, indicating that there is also an increase in 5-HT2 receptor responsiveness in the socially-isolated animals. In general, the results indicate post-synaptic 5-HT receptor supersensitivity in isolation-reared rats and these receptor changes may be involved in the behavioural profile observed in such rats. 相似文献

医学高等教育,是一种生命科学理论、人体科学技术与自然科学知识相结合的超综合性教育活动,是关于人与人服务的社会特点而开展的知识传授、技术传递、思维培训、个人社会技术引导的"人"的教育过程.由此赋予该专业的课程门类众多、专业理论纵深、知识技术要求娴熟、医德意识最大唤醒等多重功能,不仅基础课程课时量大,而且知识链条关系十分紧密,课程的排列与进度只能是递进式的,因而长时间周期是实施医学教学的第一保证. 相似文献

循证医学与中医学关系及设想初探 总被引:1,自引:0,他引:1
循证医学主要研究内容是提供证据和应用证据,其与中医相同之处是重视证据,重视整体观。中医辩证是通过四诊收集证据,将诊查结果作为辩证、立法、用药的依据。循证医学的核心思想是寻求证据,应用证据。前者用于诊断、后者注重对诊断和治疗结果的分析评价。中医重视整体观,重视从局部与整体有机的联系上分析疾病的病机变化。治疗上重视人体整体 功能状态的调整和改善。而循证医学也具有整体观,突破以往以疾病为中心的模式,倡导临床措施和医疗决策以病人为中心。为促进循证中医药学的发展,建议制作中医药的系统评价;进行循证中医药学在临床实践中的应用研究;组织评价方法研究小组;建立中医临床评价研究资料库。 相似文献
