136例阿片类药物依赖者SCL-90的评定结果分析

本文应用ＳＣＬ－９０对１３６例阿片类药物依赖者进行测评，并与正常人进行对照分析。结果显示研究组总分及各因子分与正常组相比差异有显著性。说明毒品滥用人群心理问题严重，突出表现在焦虑、抑郁等几方面，提示戒毒治疗仅进行临床脱毒治疗是远远不够的，还必须重视这一人群的心理问题，并加以矫正，才能提高工作成效     

Respiratory health status in swine producers using respiratory protective devices

A cross-sectional survey on respiratory health in swine producers showed that 30% of 301 examined men usually used a dust mask when working inside a barn. They did not differ significantly from dust mask nonusers in respect to respiratory symptoms and lung function. This analysis was undertaken to determine whether the respiratory health of dust mask users was associated with reasons why they had started individual respiratory protection. The subjects were recontacted in order to identify those who started using a mask to deliberately prevent symptoms (42 men) and those who started protection because of pre-existing respiratory symptoms (44 men). Not unexpectedly, betweengroup comparisons of respiratory symptoms and lung function suggest that swine producers who wear dust masks for preventive purposes have better respiratory health than those who wear dust masks because of symptoms or those who do not use individual respiratory protection. The individual reasons for starting dust mask usage should be examined among potential determinants of the outcomes of prospective studies which can then provide more valid assessment of the effect of individual respiratory protection. © 1993 Wiley-Liss, Inc.     

Negative symptoms in schizophrenia: considerations for clinical trials

There is little agreement about the methodology of clinical trials of antipsychotic drugs in patients with negative symptoms. A literature review revealed wide variation in experimental design, rating scales and study duration. This reflects differing views as to the definition and response to treatment of negative symptoms. Some degree of standardization would improve comparability of studies and aid the development of new compounds. Patients included in such studies should have displayed negative symptoms for at least 6 months. Depressive symptoms, positive schizophrenic symptoms and extrapyramidal signs may all influence or be confused with negative symptoms and may respond to treatment; they should be at a low level at baseline and should be measured during the study period. Studies should last at least 8 weeks. Several scales are available for measuring negative symptoms and are reviewed; a global impression score should be used additionally.     

Sulpiride in negative schizophrenia: A placebo-controlled double-blind assessment

Twenty-four chronic schizophrenic long-stay hospital patients were identified, who had not received neuroleptic drugs for 8–30 (average 8 months) and met or exceeded a minimum criterion of severity of negative symptoms. They were rendomly alocated to either sulpiride 200 mg twice daily or matching placebo, on a double-blind basis for 12 weeks. The results showed that low-dose sulpiride was significantly better than placebo in relation to improvements in negative symptoms. The changes in social behaviour were complex and not obviously related to symptom improvement; exhibited abnormal behaviour, a major factor in preventing successful return to the community, consistently improved only on the active drug.     

腕管综合征主要症状体征敏感性与特异性的比较

目的　比较腕管综合征 (carpaltunnelsyndrome ,CTS)主要症状、体征的敏感性与特异性。方法　对 10 1例 ( 162只手 )进行症状严重程度与功能状况的询问 ,感觉、运动功能的检查 ;其中 62只手在术后 6周再次测定。结果　 162只患手中 15 8只具有典型症状 ( 98% )。Phalen征、前臂正中神经加压征、Semmes Weinstein单丝纤维测试阳性率分别为 98%、96%、82 %。 87%的患手出现肌力下降 ,拇短展肌肌力测定 (定量法 )结果显示 ,与徒手法相比 ,不同性别间、术前与术后的差异均具非常显著意义 (P <0 .0 1)。结论　典型症状、Phalen征、前臂正中神经加压征、拇短展肌肌力变化的敏感性与特异性最高 ,拇短展肌肌力定量法测定是判断腕管综合征严重程度、评定疗效的一个良好的客观指标。     

心理学研究中的科学方法与非科学方法

自心理学被界定为一门科学以来 ,对心理学的研究便十分强调研究方法的科学性。那些被认为是不科学的方法 ,如内省、思辨、假设、演绎等被长期排斥在主流心理学的研究方法之外。这虽是学科研究进步的表现 ,但也暴露出心理学研究中唯科学方法的缺陷。由于心理学研究对象的特殊性 ,非科学方法仍是心理学研究中的一种重要方法 ,心理学史上的一些重要成就表明了非科学方法的应用价值。心理学研究中的科学方法与非科学方法并不是对立的。人本主义心理学大胆引进非科学方法 ,兼收并蓄 ,其主张被越来越多的人接受。     

SARS流行期间肺炎患者的临床表现和胸部影像变化的探讨

目的 探讨SARS流行期间肺炎患者的临床表现和胸部影像变化特点。方法 对76例SARS流行期间发热留观室收治的肺炎患者的临床表现及胸部影像进行分析。结果 (1)此组肺炎患者多为青壮年(占60．53％)，无固定职业或职业性质流动性较大者居多(69．74％)；(2)临床特征主要是发热，以中高热为多见(80．26％)，发病早期部分患者呼吸道症状并不明显(67．10％)，外周血WBC在正常或低于正常范围(85．53％)，淋巴细胞比例减少(75．00％)；(3)肺部CT表现为不同程度的炎性浸润；病灶形态以斑片状和球形多见(77．63％)；病灶常位于肺周边，常出现支气管气像；动态观察病变影像大多无明显进展(88．16％％)，经治疗均完全吸收。结论 SARS流行期间普通肺炎与非典型肺炎有相似的临床及胸部影像表现；肺部CT扫描能早期发现肺炎患者的异常阴影，明显优于胸片，但无特异性。因此，在SARS流行期间发热诊室医务人员应加强肺部炎性改变的早期诊断和鉴别诊断水平。

Prognostic implications of the motor symptoms of Parkinson's disease with respect to clinical,computertomographic and psychometric parameters

Summary Forty-four Parkinson patients (19 patients of the rigid-akinetic type, 13, of the rigid-akinetic-tremor type, and 12, of the tremor type) were included in a study in order to analyse correlations of the expression of the motor symptoms tremor, rigidity, akinesia, with other clinical parameters, computertomographic aspect of brain atrophy and psychometrically assessed cognitive parameters. Rigidity and akinesia are significantly positively correlated with the severity of motor dysability, stage of the disease, and brain atrophy, as is akinesia with a history of pharmacotoxic psychosis. Tremor is significantly negatively correlated with motor dysability, stage of the disease, and history of pharmacotoxic psychosis. Akinesia is correlated with visuomotor dysfunction (tested with Bender Gestalt Test) and rigidity with the depression score (Zung scale). The tremor type is favorable, the rigid-akinetic type unfavorable with respect to motor disability and psychosis.
