拓扑流体力学是理性力学的一个重要研究方向,在理论上具有重要价值,在实践中日益显出独特的作用.本文试对该方向进行综述性介绍,目的是吸引更多的国内科研工作者进入这一重要领域.本文的重点放在流体螺度(Helicity)的拓扑内涵方面.除了列出螺度与数学纽结场论的关系(即与互缠绕、自缠绕数以及作者近年来发展出来的流体纽结多项式拓扑不变量之间的关系),还介绍了国际上在流体纽结复杂系综的能量-结构复杂性关系方面的研究.最后,通过超流涡旋纽结/链环重联的具体实例,展示了这一领域当中典型的数值计算方法.我们希望通过这种理论推导与数值计算同时呈现的方式,使读者对这一国际前沿交叉领域的核心问题、研究方法以及科研中可能面对的技术困难获得一个整体的了解和把握.

Anxiety disorders are among the most common of all mental disorders and their pathogenesis is a major topic in psychiatry, both for prevention and treatment. Early stressful life events and alterations of hypothalamic pituitary adrenal(HPA) axis function seem to have a significant role in the onset of anxiety. Existing data appear to support the mediating effect of the HPA axis between childhood traumata and posttraumatic stress disorder. Findings on the HPA axis activity at baseline and after stimuli in panic disordered patients are inconclusive, even if stressful life events may have a triggering function in the development of this disorder. Data on the relationship between stress, HPA axis functioning and obsessive-compulsive disorder(OCD) are scarce and discordant, but an increased activity of the HPA axis is reported in OCD patients. Moreover, normal basal cortisol levels and hyperresponsiveness of the adrenal cortex during a psychosocial stressor are observed in social phobics. Finally,abnormal HPA axis activity has also been observed in generalized anxiety disordered patients. While several hypothesis have attempted to explain these findings over time, currently the most widely accepted theory is that early stressful life events may provoke alterations of the stress response and thus of the HPA axis, that can endure during adulthood, predisposing individuals to develop psychopathology. All theories are reviewed and the authors conclude that childhood life events and HPA abnormalities may be specifically and transnosographically related to all anxiety disorders, as well as, more broadly, to all psychiatric disorders.

AiM: To investigate the complex relationships between resting energy expenditure(REE), eating psychopathology, and Hypothalamus Pituitary Adrenal axis functioning in patients with eating disorders. METHODS: The study was designed as a crosssectional survey, and it was planned by the Clinic for Eating Disorders of the University of Florence(italy). The protocol was approved by the Ethics Committee of the institution. Twenty two anorexia nervosa and twenty one Bulimia Nervosa patients were assessed by means of a clinical interview and the structured clini-cal interview for diagnostic and statistical manual of mental disorders, fourth edition. Eating attitudes and behaviour were specifically investigated by means of the eating disorder examination questionnaire(EDE-Q). Patients were also evaluated by means of the symptom checklist(SCL 90-R), REE was measured by means of indirect calorimetry, and blood cortisol morning levels were evaluated. RESULTS: Both anorexia nervosa and bulimia nervosa patients showed a reduced REE as compared with predicted REE. Body mass index(BMi) was positively associated with resting energy expenditure in Bulimics, whereas a strong, negative association between BMi and REE was observed in Anorectics. The pattern of associations between variables supported a mediation model, where shape concern accounted for variations in REE and cortisol levels(mediator), and variations in the mediator significantly accounted for variations in REE. When these associations where taken into account together, the relationship between shape concern and REE was no longer significant, whereas the association between cortisol levels and REE retained its significance, showing strong evidence for a single, dominant mediator. Anorectics and Bulimics showed an opposite pattern of association between BMi and REE. in Anorectics only, a higher REE was associated with a more severe eating disorder specific psychopathology, and cortisol levels represent a possible mediating

氧疗应是急诊最为广泛使用的治疗方法之一,但因为无人使用氧以外的任何气体作为安慰剂来进行盲法实验,也可能是由于涉及到我们每天都在呼吸着的空气中的一种气体,人们觉得无所谓的原因,因此氧疗也是缺乏有利证据的治疗方法之一.针对一些特定疾病的氧疗指南(如COPD患者的长期氧疗)在既往文献中已有报道,但往往忽略了氧疗在急诊中的作用.英国胸科协会(BTS)近期出版的急诊氧疗使用指南填补了这一空白,尤其是对于危重患者的治疗[1].
