细胞因子和抑郁症

在心理神经免疫学领域,越来越多的证据表明神经和免疫之间存在双向交流通路,免疫系统可能在一些心理精神障碍中具有重要作用。“抑郁症的细胞因子假说”认为细胞因子作为神经调质,可能在抑郁症的病因和病理过程中具有重要作用。这个假说得到了很多证据的支持。而在动物身上应用前炎性细胞因子也能够引起与人类抑郁症行为症状非常类似的“病态行为”。研究认为外周细胞因子通过信号传导进入脑内与中枢产生的细胞因子共同作用于下丘脑－垂体－肾上腺轴和5－羟色胺系统,从而导致抑郁症。细胞因子的中枢效应可以解释很多抑郁症状,“抑郁症的细胞因子假说”为探讨抑郁症状的机制和治疗抑郁症提供了一个新的视角

卵巢肿瘤蒂扭转误诊、漏诊分析

回顾性分析了我院10年间17例卵巢肿瘤蒂扭转病例,并从患者年龄、临床表现、辅助检查、治疗情况等方面对误诊、漏诊的原因进行了分析.发生在青少年、儿童的卵巢肿瘤蒂扭转误诊率为52.9%,发生在绝经后妇女者误诊率为29.4%,最易误诊为急性阑尾炎,临床医生应予以高度重视.     

Several programming models with unascertained parameters and their applications

Several programming models are introduced with the consideration of available unascertained information. In this case, the so‐called unascertained information is some numerical values whose ranges are known but their exact values are not. These models resolve several vital weaknesses of the traditional programming methods to a certain degree. Our study includes considerations of linear and non‐linear programming models with grey parameters, grey 0–1 programming, and satisfactory and quasi‐optimal solutions of grey linear programmings. Finally, some practical applications are given in order to test the applicability of our theory. Copyright © 1999 John Wiley & Sons, Ltd.     

归类不确定时特征推理的单类说理论

人们不能完全确定某个事物应该归入哪个类别的情境,被称作“归类不确定的情境”。关于归类不确定情境中的特征推理,目前有两种理论解释：Anderson的理性模型和Murphy与Ross的“单类说”。理性模型认为,在归类不确定情境中,预测事物是否具有某个特征时,人们会考虑该事物可能属于的所有类别,既会考虑靶类别的信息,又会考虑非靶类别的信息。单类说则相反,认为在归类不确定情境下的特征推理,人们只会考虑靶类别的信息,而不考虑非靶类别的信息。该文重点介绍了单类说的发展进程,并对归类不确定情境中的特征推理进行了展望     

Individual differences in students' retention of knowledge and conceptual structures learned in university and high school courses: the case of test anxiety

The purpose of this research was to assess individual differences in students' retention of knowledge several years after studying the material. Assessment of retention of materials as a function of students' test anxiety can allow one to evaluate whether high test-anxious students' original deficient academic performance and organization of the materials are due to a retrieval deficit or a deficit in learning and knowledge organization. In two studies, students with different test-anxiety levels completed tasks that enabled us to evaluate both students' levels of knowledge and their cognitive organization of the materials. The tasks were administered either at the end of the course, or at different retention intervals up to 7 years after the end of learning. Results indicated that whereas high test-anxious students tested at the end of the courses performed worse than other students on tests of knowledge and cognitive organization, high test-anxious students tested at various retention intervals after the courses performed as well as other students. The theoretical and practical implications of these results are discussed. © 1997 John Wiley & Sons, Ltd.     

情绪应激体液免疫调节作用的影响因素

以给予经定时喂水训练大鼠空瓶刺激为情绪性心理直激源,研究了应激源给予的频率及抗原免疫前或后给予应激刺激等因素对此情绪应激体液免疫调节作用的影响：结果表明,特异性抗原OVA免疫前3次,每次30分钟的情绪应激刺激不影响大鼠的抗OVA抗体水平和脾脏指数;抗原免疫后,同样频率和持续时间的情绪应激能一定程度地降低体液免疫功能;而抗原免疫后14次,每次10分钟的情绪应激刺激则显著降低大鼠的抗OVA抗体水平和脾脏指数。该研究证实,抗原免疫后、反复多次的情绪应激刺激能显著抑制大鼠的原发性体液免疫功能。     

双重作业的颜色编码方式对作业绩效的影响

研究探讨了不同颜色编码方式对双重任务操作绩效的影响。实验结果证明：若采用同类颜色编码方式,同时操作的两种作业就会产生结构限制,降低双重任务操作绩效;相反,若采用异常颜色编码方式,将有效地减少双重任务操作的结构限制,使双重任务的操作绩效得到提高。     

朱震卦变思想解析

卦变说是朱震易学思想中体系最为庞杂、但却最能体现其作为象数派易学家的部分。他对“卦变”做出了多种解读,提出凡是由一卦演变出另一卦及有关意义的思想,皆可视为卦变。虽然其中难免有牵强附会之处,但其内在的思维理路,就是试图以“变”为主体内容,以卦变为基础,统率易学中的相关体例。     

Why Subjectivists About Welfare Needn't Idealize

It is commonly thought that subjectivists about welfare must claim that the favorable attitudes whose satisfaction is relevant to your well‐being are those that you would have in idealized conditions (e.g. ones in which you are fully informed and rational). I argue that this is false. I introduce a non‐idealizing subjectivist view, Same World Subjectivism, that accommodates the two main rationales for idealizing: those given by Peter Railton and David Sobel. I also explain why a recent argument from Dale Dorsey fails to show that subjectivists must idealize. Because Same World Subjectivism is a plausible non‐idealizing view, subjectivists about welfare needn't idealize.
