创建良好的心理环境提供全方位优质服务

医院为患者创建温馨、舒畅的心理环境是当前医院改革中亟待解决的极其重要的任务之一。本文从①充分了解患者的心理需求；②注意患者的不良心理因素；③注意医务人员的不良因素三个方面阐述医院如何为患者创造良好心理环境及其重要性。并重点强调自觉培养自身良好的心理素质，保持稳定良好心态及自控力，尊重、理解患者，学习、实践与患者的沟通技巧，增强责任感，树立良好的白衣天使形象等要素是创建的基础。     

青少年精神分裂症患者家庭因素的研究

目的:探讨青少年精神分裂症患者的发病和家庭因素的相关性.方法:采用父母养育方式评价量表(EMBU)及家庭环境量表中文版(FES-CV)对60名青少年精神分裂症患者进行测评并与60名健康青少年进行对照及相关分析.结果:青少年精神分裂症患者父母养育方式与正常组对照显示:其父亲惩罚严厉、拒绝否认因子分显著高于对照组,情感温暖、理解因子分显著低于对照组(P＜0.05或P＜0.01);其母亲过分干涉过度保护、偏爱被试因子分显著高于对照组;母亲的情感温暖理解、过度保护、偏爱被试因子分高于父亲(P＜0.05或P＜0.01).家庭环境的亲密度、情感表达、文化性、娱乐性的因子分低于对照组,矛盾性和控制性均高于对照组(P＜0.05或P＜0.01).相关分析显示:父亲过度保护与母亲拒绝否认,及母亲过度保护与父亲拒绝否认因子之间呈负相关(r≥0.8);父亲与母亲EMBU相同因子得分具有相关关系(r≥0.6).结论:不良的家庭环境和父母养育方式对青少年精神分裂症的发病起一定作用,具有相关性.     

Conformations of neurotensin in solution and in membrane environments studied by 2-D NMR spectroscopy

Two-dimensional HOHAHA and ROESY nuclear magnetic resonance techniques are used to obtain complete proton resonance assignments and to perform a conformational investigation of the neuropeptide neurotensin (pGlu-Leu-Tyr-Glu-Asn-Lys-Pro-Arg-Arg-Pro-Tyr-Ile-Leu) in aqueous solution, methanol, and membrane-mimetic [deuterated sodium dodecylsulfate (SDS)] environments. Results suggest the absence of discernible elements of secondary structure in water and methanol. ROESY spectra confirm that Lys-Pro and Arg-Pro peptide bonds are all-trans, but that a significant population of cis Arg-Pro bonds arises in aqueous solution, which increases in the environment of SDS micelles. The conformational ensemble of the peptide is observed to narrow as it becomes bound through its cationic mid-region to SDS micelles, with the accompanying advent of local extended structure. The overall results indicate the inherent conformational flexibility of neurotensin, and emphasize the environmental dependence of conformation in peptides of medium length.     

神经症与精神分裂症患者家庭环境的对照研究

目的：探讨神经症患者家庭环境的特点。方法：采用家庭环境量表中文版，对50例神经症患者进行调查 ，并按1：1配对原则分别与50例精神分裂症，50例正常对照组进行比较。结果：（1）与正常对照组相比神经症患者的家庭关系表现为低亲密度、高矛盾性及道德宗教观的差异；（2）与精神分裂症相比仅表现为控制性差，而两对照组之间表现为精神分裂症患者家庭低亲密度、高矛盾性、文化娱乐性缺乏和道德宗教观的不同。结论：不良的家庭环境，对子女患精神疾病有重要影响，但它们之间没有明显特异性。     

Increased heritability for lower IQ levels?

Dettermanet al. (1990) presented evidence based on twins that the heritability of IQ may be higher in the lower part of the IQ range. We first offer an alternative test for differential heritability across the IQ range, based on the analysis of absolute intrapair differences of monozygotic versus dizygotic twins. We then review two previous studies, each containing more twins than the sample of Dettermanea al., which examined the distribution of intrapair absolute differences. In contrast to the study of Dettermanet al., both yielded results more compatible with higher heritability in the upper range of IQ. We discuss various interpretations of these findings and show how our proposed test might aid in distinguishing among them.     

吉林省七年鼠情监测结果分析

吉林省经七年来的鼠情监测,基本查清与人们接触密切的鼠类,特别是传播疾病的主要鼠类的分布规律,分析出我省家鼠有两个高峰(6月和10～11月),野鼠也有两个高峰(6月和10月),这与我省流行性出血热两个高峰相吻合,鼠峰在病峰之前。1986年以后,由于我省开展大规模灭家鼠活动,家鼠高峰已不存在规律性。通过几年来的灭鼠活动,使家鼠密度呈下降趋势,城镇褐家鼠和小家鼠构成比发生变化。城镇未爆发家鼠型流行性出血热。鼠情监测为灭鼠防病工作提供了科学依据。     

Increased sensitization in urban vs. rural environment – Rural protection or an urban living effect?

In a population-based longitudinal cohort study, we tested the hypothesis that children growing up in a high-traffic polluted urban area (UA) in the Athens' basin have higher prevalence of allergies and sensitization when compared with those growing up in a Greek provincial rural area (RA). We recruited 478 and 342 children aged 8-10 living in the UA and the RA, respectively. Respiratory health was assessed by a parent-completed questionnaire in three phases: 1995-96 (phase 1), 1999-2000 (phase 2), 2003-04 (phase 3) and skin-prick testing to common indoor and outdoor aeroallergens was performed at phases 1 and 2. Reported asthma and eczema did not differ between the two areas, whereas reported hay fever was persistently more prevalent in the UA than in the RA (16.5%, 17.0%, 18.2% vs. 7.0%, 8.3%, 9.6%, respectively). Sensitization was more prevalent in the UA at both phases (19.0% vs. 12.1% in phase 1, 20.0% vs. 14.1% in phase 2). Residential area contributed independently to sensitization to >or=1 aeroallergens (OR: 0.29; 95% CI: 0.13-0.66; p = 0.003) and to polysensitization (OR: 0.28; 95% CI: 0.10-0.82; p = 0.020) in phase 1. These associations were independent of farming practices. No significant contributions were found in phase 2. Our results suggest that long-term exposure to urban environment is associated with a higher prevalence of hay fever but not of asthma or eczema. The negative association between rural living and the risk of atopy during childhood, which is independent of farming practices, implies that it is mainly driven by an urban living effect.
