摘要： 探讨糖尿病并发周围神经病变的早期诊断问题,我们对50例无神经系统症状的糖尿病患者给以神经电生理检查,和本实验室正常对照组比较,感觉神经传导速度(SCV)减慢24例(48%),其中6例肌电图呈神经原性改变。单神经损害14例,多神经损害10例。以下肢损害为主,合并有上肢神经损害。

摘要： 国际疼痛研究室（ＩＡＳＰ）对疼痛下的定义是：疼痛是伴随着现有的或潜在的组织损伤的一种令人不愉快的感觉和情绪上的感受［１］。随着研究的深入，人们对疼痛的认识在不断深化。开始认为疼痛是过度刺激的结果，并可通过所有的外周感觉神经传递。２０世纪初用记录神经冲...

摘要： 我今年32岁了,我永远不会忘记10年前的盛夏与大学同学们携游匡庐的往事。那时,我们风华正茂,青春如诗。远征三叠泉,夜登五老峰,我们不知疲倦,更不知人间有愁。现在我前瞻未来,常独自暗暗怀疑:那样神仙般的日子是否就一去不返了?那次畅游庐山,我得了个“夜游神”的绰号。故事是这样的:当时,我们住宿在庐山医院附近的一家宾馆,四周绿荫匝地,鸟雀啁啾。7月18日夜间,

摘要： 慢性疲劳综合征是以无力、疲劳和认知能力下降等症状为特征的病症。许多学者相信,此综合征系因中枢神经系统发生改变所引起,问题不在外周(肌肉)。许多症状很难同患者的去适应(deconditioning)区别。今后的研究应着重研究神经病理学、精神病理和神经心理之间的关系方面。

摘要： Crustaceans serve as an ideal model for the study of calcium homeostasis due to their natural molting cycle. Demineralization and remineralization of the calcified cuticle is accompanied by bidirectional Ca transfer across the primary Ca transporting epithelia: gills, antennal gland (kidney), digestive system, and cuticular hypodermis. The review will demonstrate how a continuum of crustaceans can be used as a paradigm for the evolution of Ca transport mechanisms. Generally speaking, aquatic crustaceans rely primarily on branchial Ca uptake and accordingly are affected by water Ca content; terrestrial crustaceans rely on intake of dietary Ca across the digestive epithelium. Synchrony of mineralization at the cuticle vs. storage sites will be presented Physiological and behavioral adaptations have evolved to optimize Ca balance during the molting cycle in different Ca environments. Intracellular Ca regulation reveals common mechanisms of apical and basolateral membrane transport as well as intracellular sequestration. Regulation of cell Ca concentration will be discussed in intermolt and during periods of the molting cycle when transepithelial Ca flux is significantly elevated. Molecular characterization of the sarco-/endoplasmic reticular Ca pump in aquatic species reveals the presence of two isoforms that originate from a single gene. This gene is differentially expressed during the molting cycle. Gene expression may be regulated by a suite of hormones including ecdysone, calcitonin, and vitamin D. Perspectives for future research are presented.

摘要： This paper concentrates on the basic properties of ''consciousness'' that temporal coding is postulated to relate to. A description of phenomenal consciousness based on what introspection tells us about its contents is offered. This includes a consideration of the effect of various brain lesions that result in cortical blindness, apperceptive and associative agnosia, and blindsight, together with an account of the manner in which sight is regained after cortical injuries. I then discuss two therories of perception-Direct Realism and the Representative Theory. This includes a discussion of the concept of the body-image, phantom limbs, the alleged projection of sensations, the ontological status of phenomenal space, the homunculus argument, the validity of topographic coding, the difference between the stimulus field and the visual field, and two theories of brain-mind relationship-the Identity Theory and the Bohr-Heisenberg theory of brain-mind complementarity. Finally I suggest that the binocular rivalry obtained in the case of the stroboscopic patterns that result from intermittent photic stimulation of one eye, when used in animal experiments with unit recording, offers a good experimental method of investigating the binding problem.

摘要： 10 female physical education students were given posthypnotic suggestions alluding to economy of effort in exercise. These suggestions were affirmed under self-hypnosis over two weeks. Experimental subjects pedalled on an exercise bi cycle for 20 min, at 60% of their maximal work capacity while listening to suggestions from a hypnotist. The Control group (n=9) showed no differences between mean pretest and posttest scores on physical self-efficacy, trait anxiety, state anxiety, heart rate, blood pressure, and perceived rate of exertion. The average systolic blood pressure of the experimental group was the only positive significant difference between the pretest and posttest scores.

摘要： In order for primary care clinicians to address the complex needs of their patient population they must be able to collaborate with mental health professionals. The peculiar need for this collaboration arises from the mind-body split embedded in our cultural heritage and the resulting professional separatism. A brief review of that history is followed by sections on the spirit of collaboration, the spectrum of collaboration, key ingredients for effective collaboration, and some thoughts about the future of collaboration.
