脑囊虫病人血清、脑脊液中抗体在MRI各期的变化

目的 检测脑囊虫病人血清和脑脊液中抗体在MRI各期的变化。方法 用抑制性ELISA法检测血清及脑脊液中的抗体。同时根据MRI表现将病例分为活动期、退变期、非活动期。结果 在69个病例中，脑脊液中抗体阳性率分别是：活动期75．00％，退变期62．50％，非活动期17.24％；血清中是81．25％、16．67％、22．22％。在相应各期中，脑脊液和血清抗体阳性率无显著性差别。结论 在影像学的不同时期抗体阳性率存在明显的变化。     

肺癌组织中血管内皮生长因子受体Flt1及KDR的表达及其与肿瘤转移和预后的关系

①目的　探讨肺癌中血管内皮生长因子受体Flt1、KDR的表达与其转移及预后的关系。②方法　应用免疫组织化学PowerVisionTM PV90 0 0法 ,测定 75例肺癌标本中Flt1、KDR的表达。③结果　肺癌组织中Flt1、KDR的表达较为广泛 ,主要位于肿瘤细胞胞浆及胞膜上 ,纤维母细胞和血管内皮细胞胞浆中亦有表达。Flt1、KDR在肿瘤细胞中的阳性率均显著高于在间质纤维母细胞中的表达 (χ2 =6 .0 7、5 .88,P <0 .0 5 )。肿瘤细胞及纤维母细胞中该两种受体的阳性率在不同年龄、不同性别及不同病理类型、不同病理分级之间差异均无显著性 (χ2 =0 .0 1～4 .84 ,P >0 .0 5 ;P =0 .2 9～ 0 .79)。肿瘤细胞中Flt1、KDR的阳性表达率在 3组不同大小的肿瘤间差异均有显著性(χ2 =1 0 .35、7.2 9,P <0 .0 5 ) ,而纤维母细胞中差异均无显著性 (χ2 =2 .86、2 .5 6 ,P >0 .0 5 ) ;肿瘤细胞及纤维母细胞中Flt1、KDR的阳性率在淋巴结有、无转移两组间的差异均有显著性 (χ2 =4 .72～ 9.32 ,P <0 .0 5 ) ,在 3组不同术后生存时间病人间亦均有显著性差异 (χ2 =8.81～ 1 9.1 9,P <0 .0 5 )。肿瘤细胞中Flt1、KDR的表达呈极显著性正相关 (r =0 .4 4 ,P <0 .0 1 )。④结论　肺癌的生长主要依赖自分泌机制 ,联合检测Flt1、KDR可能对肺癌转移     

'Not everything that can be counted counts and not everything that counts can be counted'– towards a critical exploration of modes of satisfaction measurement in sheltered housing

This paper reflects on a research project funded by a consortium of leading sheltered housing (SH) providers and their regulatory body, the Housing Corporation. The project aimed to ascertain which aspects of SH older people perceived to be central to their satisfaction and the methods they judged most appropriate to measuring this. We outline key policy developments of importance to SH (specifically the development of performance measurement regimes), and changes in the nature of SH, which are driving providers to re‐evaluate how they measure user satisfaction. We discuss the aims of the project, our methodology and findings, and conclude by raising critical questions about the process of measuring satisfaction within an increasingly managerialised housing system. We argue that this favours standardised methods of information gathering (such as questionnaires) rather than engage with clients in order to develop methods and systems capable of eliciting qualitative issues of concern to them. Our conclusions are, we believe, applicable to health and social care provision, where similar tensions exist around performance measurement and user satisfaction.     

护士社会支持与焦虑状况相关因素调查分析

目的了解护士的社会支持与焦虑状况的相关因素,为心理干预提供理论依据.方法采用社会支持评定量表、状态焦虑量表(S-AT)对100名女护士进行调查,并分析其相关因素.结果护士社会支持评分为(37.22±6.94)分,S-AT评分(42.70±7.20)分;护士社会支持与焦虑状态呈负相关,即社会支持越高,焦虑状态越低;年龄<25岁、工龄<5年、未婚、合同护士社会支持明显偏低.结论良好的社会支持有助于减轻护士心理压力,是维护护士身心健康的重要因素.     

Risk factors for asthma in adolescents in a large urban region of Brazil.

BACKGROUND: Identify risk factors for asthma in adolescents from S?o Paulo, Brazil. METHODS: total of 528 adolescents (141 asthmatics, 387 control subjects) from the ISAAC study (phase III) were submitted to a complementary questionnaire to evaluate risk factors, through response to questions regarding personal history, environment, and diet and an agreement to undergo the skin prick test (SPT) for aeroallergens. RESULTS: Positive SPT to at least one allergen occurred in 49.4% adolescents. The risk factors for asthma were: prematurity (OR: 3.84, 95% CI: 1.54-9.64), rhinitis (OR: 3.18, 95% CI: 1.71-5.91), positivity in the SPT (OR: 2.81, 95% CI: 1.48-5.32), eczema in characteristic skin-folds (OR: 2.86, 95% CI: 1.13-7.26), and an allergic mother (OR: 2.01, 95% CI: 1.02-3.93). The consumption of cooked vegetables was a protective factor for asthma (OR: 0.37, 95% CI: 0.18-0.79) CONCLUSIONS: Asthma is a multifatorial disease. An allergic mother, aeroallergen sensitization, rhinitis, eczema and prematurity were considered risk factors and the consumption of cooked vegetables was considered a protective factor for asthma in this population.
