北欧清洗消毒现状——消毒过程如何减少医院感染

1“消毒”定义的发展250多年前,在瑞典的医疗工作中已经开始使用“消毒”(Disinfection)作为术语,主要指控制或减少医院内的怪味。当时微生物致病的重要性依然不为民众所知。消毒的现代定义是指去除或杀灭致病微生物,以达到清洁要求。消毒的理想方式是完全去除表面的微生物,当然如果真能做到这一点,物品的表面就不止达到了消毒要求,而应为无菌状态了。2现代消毒技术水作为溶剂和优良的载体,对清洁过程起着至关重要的作用。但是,单纯用水或水溶液清洗的方法达不到去除所有微生物的要求。这样,消毒过程要分两步,第1步是通过清洗或机械手段尽…     

城市血吸虫病综合防治措施的研究

目的探索快速控制城市血吸虫病流行的综合措施。方法在城市血吸虫病流行区选择3个试点现场,南津港、太平桥2个点采取以化疗为主的综合防治措施,小柳叶洲点采取以环境改造灭螺为主的综合防治措施。结果南津港点3年居民血吸虫感染率分别为2.80%、2.60%和2.24%,并发生急性血吸虫病2例;感染螺平均密度分别为0.0009、0.0027、0.0020只/0.1m2。小柳叶洲点3年无居民粪检阳性者,无急性血吸虫病例,哨鼠感染率为0,没有查到感染性钉螺。太平桥点3年居民感染率分别为1.18%、0.20%和0.26%,无急性血吸虫病例,家畜感染率分别为6.35%、3.57%和3.85%,2004年发现感染性钉螺,平均密度为0.0001只/0.1m2。结论在城市血吸虫病流行区,采取以环境改造灭螺为主、人群化疗、健康教育、药物灭螺灭蚴的综合防治措施能快速控制疫情。采取以化疗为主的综合防治措施,难以有效控制疫情。     

Irritable bowel syndrome and health-related quality of life: a population-based study in Calgary, Alberta.

BACKGROUND: Little is known about the health-related quality of life (HRQOL) of nonclinical samples of people with irritable bowel syndrome (IBS) in Canada. In a pilot survey, the impact of IBS on HRQOL using a population-based, urban sample was examined. METHODS: A random sample of Calgary residents (18 years of age or older), selected by random digit dialing (n=1521), completed a structured questionnaire including ROME II Criteria and Medical Outcomes Study Short-Form 12-Item Health Survey, version 2 (SF-12v2). The mean scale and summary scores of SF-12v2 for those who did and did not meet ROME II criteria and for those who met ROME II criteria with and without visiting a physician in past three months were determined and compared using multiple regression analyses. RESULTS: Of the 951 households successfully contacted, 590 (62%) were willing to participate, of which 437 (74%) individuals were recruited. One hundred ten IBS cases (81 of which were women) and 327 non-IBS controls (180 of which were women) were identified. All of the eight mean scale scores and the two mean summary scores were significantly lower in people with IBS than in those without, whether or not adjusting for demographics. Forty-four of the 110 IBS cases (40%) sought medical help. Significantly lower mean physical component score and three scale scores (general health, social functioning and role physical) were found in those who sought medical help than in those who did not. CONCLUSIONS: People with IBS experience significant impairment in HRQOL, including both physical and mental well-being. People with IBS who seek medical help report worse physical health than those who do not, but their mental health is no different.

磁共振成像在肝移植术后并发症诊断中的应用

目的探讨磁共振成像在肝移植并发症诊断中的价值。方法回顾分析11例肝移植术后发生并发症者的磁共振检查影像资料。结果11例患者术后出现皮肤和巩膜黄染、发热以及尿黄等症状，丙氨酸转氨酶、天冬氨酸转氨酶、γ-谷氨酰转移酶和胆红素升高．经B型超声波检查不能明确原因，采用磁共振（MRI、MRA和MRCP）检查，明确肝动脉吻合口狭窄1例；肝动脉闭塞2例；下腔静脉吻合口狭窄及血栓形成各1例；胆管吻合口狭窄4例，其中1例伴胆汁瘤形成；肝门水平非吻合口狭窄6例；肝坏死2例；肝包膜下血肿及右肾上腺出血各1例；均显示不等量的右侧胸腔积液、腹腔积液及肝门部水肿。结论磁共振一次检查可显示肝内外的多种结构，能为肝移植术后并发症的诊断提供丰富的肝脏、血管、胆道以及肝外结构的图像信息。     

Mozart effect in preschool children?

In 1993, Rauscher et al. reported a temporary increase in spatial-temporal ability after listening to Mozart's music. This led to numerous replication and extension studies with mixed findings in the past decade. This study investigated the 'Mozart effect' in preschool children. Forty-one boys and girls, aged three to five, attempted a series of pencil-and-paper maze tests after each of three listening conditions: Mozart's Piano Concerto in A Major (K488), age-appropriate popular music and silence. Overall, there were no statistically significant differences among the three interventions. The results are discussed in relation to the findings of other investigations of the Mozart effect, and the need for further investigation of possible trends.

目的探讨重组腺病毒相关病毒（rAAV）-阳离子脂质体（LyoVec）复合载体的构建方法及其转染率评价。方法构建rAAv～GFP，rAAv—LyoVec复合载体及rAAV—GFP—LyoVec。倒置荧光显微镜观察，测定rAAV—GFP，LyoVec—GFP及rAAV—GFP-LyroVec对定量C6细胞的转染率，筛选出高转染率载体。结果rAAV—GFP组24、48、72和96h转染率分别为16％、23％、21％和9％；LyoVec-GFP组为28．5％、33％、32％和11％；rAAV—GFP—Lyovec组为49％、59％、64％和20％。rAAV-GFP—LyoVec纽分别在24、48、72和96h的转染率显著高于rAAV—GFP组（P〈0．01）及LyoVec—GFP组（P〈0．01）。结论新构建rAAV—LyoVec复合载体基因的转染效率远远高于rAAV或LyoVec独立转染。     

(加味)柴芍承气汤对重症急性胰腺炎及其并发症的作用

目的探讨(加味)柴芍承气汤对重症急性胰腺炎(SAP)及其并发症的防治作用。方法65例SAP患者分为中药组35例,对照组30例。2组的内科治疗相同,中药组一经确诊即予柴芍承气汤加味银杏叶治疗,每剂煎成100~150m l,自鼻胃管内注入或口服,每日2~3次,直至患者腹痛缓解、腹胀基本消失、肠鸣恢复。分别观察2组患者治疗72 h后的PaO2、SaO2肾功能、脑病、局部并发症情况、腹痛缓解时间、肠鸣恢复时间、病死率,以及血清中血小板活化因子(PAF)、肿瘤坏死因子(TNF-α)、白介素-1(IL-1)水平变化。结果治疗72 h后中药组与对照组低氧血症的发生率分别为45.71%、73.73%,P<0.05;肾损害、脑病、局部并发症发生率以及病死率均低于对照组,但无统计学差异;腹痛缓解时间、肠鸣恢复时间均优于对照组(P<0.05);中药组血清中PAF、TNF-α、IL-1水平显著降低(P<0.01),而对照组则无明显变化。结论该汤剂对SAP及其并发症有较好的防治作用。抑制细胞因子或炎症介质可能是该汤剂治疗SAP的重要机制。
