A Preliminary Study of Negative Self-Beliefs in Anorexia Nervosa: A Detailed Exploration of Their Content, Origins and Functional Links to “Not Eating Enough” and Other Characteristic Behaviors

Objective: The study explored the semantic content and origins of negative self-beliefs, and their functional links to “not eating enough” and other behaviors, in participants with anorexia nervosa (AN). Method: Fifteen women meeting DSM-IV criteria for AN were compared with 17 dieting and 18 non-dieting women matched on age and number of years of education. The main outcome measure was a semi-structured interview. Results: Six themes were identified in the beliefs of participants with AN. These were, in order of decreasing frequency, powerlessness (present in all but three AN participants), failure, defectiveness, unattractiveness, worthlessness and emptiness. Importantly, powerlessness and failure beliefs were consistently present independent of Beck Depression Inventory-II scores. The negative early life experiences associated with these beliefs had high distress and responsibility ratings. Participants with AN reported that they employed specific behaviors, particularly ‘not eating enough,’ and ‘placating others,’ to try to reduce the cognitive and emotional impact of their negative self-beliefs. Discussion: The findings are discussed in relation to the role of powerlessness and the function of “not eating enough” in cognitive theory and therapy for AN.

肾综合征出血热患者T细胞亚群数量与白细胞介素2,4水平变化的关系

采用ABC免疫组化染色法及单克隆抗体夹心法ELISA，同步检测了34例肾综合征出血热（HFRS）患者外周血T细胞亚群数量和血清白细胞介素2和4（IL－2、IL－4）水平。发现HFRS病程中各T细胞亚群数量均有不同程度的升高，其中CDS阳性T细胞在各病期均有升高。IL－4水平升高仅见于发热期．而IL－2的升高主要在低血压期和少尿期。病程中有CD4／CD8比值的下降甚至倒置。这种比值的变化与IL－2和IL－4的动态变化有一定的相关性。结果揭示，在HFRS发病机理中存在Thl型和Th2型免疫反应等多种免疫病理机制。     

Caring for the Involuntarily Hospitalized Adolescent: The Issue of Power in the Nurse-Patient Relationship

TOPIC: The power relations between involuntarily hospitalized adolescents and their caregivers from the viewpoint of theory development in nursing and the concept of medicalization. PURPOSE: To contribute to the development of nursing theories that can guide nursing care of involuntarily hospitalized adolescents by examining the power relations between the adolescents and their caregivers. SOURCES: Published literature in medical sociology, and nursing and psychiatric ethics. Nursing and psychiatric literature, in which Michel Foucault's theories are used to explicate the disciplinary power of psychiatry. CONCLUSIONS: To empower involuntarily hospitalized adolescents nurses must both recognize the inevitable power imbalance and seek guidance from the egalitarian ideals of nursing. Nurses can draw from postmodern thinkers who dismiss the idea that one theory can explain human relationships.     

A reaction route graph analysis of the electrochemical hydrogen oxidation and evolution reactions

The reaction route (RR) graph approach recently developed by us for complex, non-linear kinetic mechanisms is applied to the hydrogen oxidation and evolution reactions. A corresponding RR graph is constructed and translated into an equivalent electrical circuit network by associating each elementary step with a characteristic resistance for the steady-state case and considering the overall reaction as a power source. It is further shown that the steady-state kinetics of the reaction can be investigated employing the conventional methods of the electrical network theory. Using a set of rate constants for the hydrogen evolution reaction (her) in alkaline solutions from the literature, the dominant RRs are identified and simplified mechanisms and kinetics derived.

对《诸病源候论》毒邪症状界定的分析

《诸病源侯论》论毒邪篇幅之多,明目之清,发前人所未发,打破传统束缚,注重临床实际。如其提出毒邪判断要以阴阳为纲;毒邪向内为病重,向外为病轻;赤白为轻,青紫黑为重;过肘膝为重,以及伤肠胃心肝脾肾均有不同的症状特征,提示了六淫从化于毒,毒邪与六淫有不同表现等问题,值得一读。     

干燥综合征与病毒感染的关系研究进展

干燥综合征是一种以口眼干燥为特征,主要累及外分泌腺的弥漫性结缔组织病。其发病可能与病毒感染、遗传和性激素异常等多种因素有关,在这些因素的共同作用下,机体免疫异常,组织损伤。与该病关系较密切的病毒有EB病毒、丙型肝炎病毒、巨细胞病毒、反转录病毒等。病毒在干燥综合征的发病机制中可能起重要的作用。
