复方熊胆眼药水对实验性兔角膜白斑的疗效观察

本实验根据中医学对角膜瘢痕的认识以及历代中医应用中药熊胆治疗角膜翳的理论和方法,配制了复方熊胆眼药水.通过复方熊胆眼药水对实验性兔角膜白斑的疗效观察和光镜下兔角膜病理形态学检查,结果提示复方熊胆眼药水有显著的退翳作用,探讨该作用是通过消除角膜的慢性炎症,增加其局部组织代谢来实现的.指出复方熊胆眼药水对临床角膜瘢痕患者的治疗及角膜移植术前的辅助治疗是有积极意义的.

降低医疗保健服务中HIV/AIDS相关歧视研究:背景、问题及研究框架

医疗保健领域中艾滋相关偏见与歧视问题已得到国际社会及众多艾滋病防治领域工作者的广泛关注。在欧洲联盟资助下,设计并实施了一个为期1年的行动性研究以探索如何降低医疗保健领域的偏见与歧视。本文回顾了偏见与歧视的概念以及UNAIDS提出的医疗保健领域艾滋相关歧视的主要表现形式,提出了本研究中的偏见与歧视的操作定义及范畴,并给出了本研究的背景及框架。     

局部浸润和神经阻滞麻醉在会阴切开中的应用分析

目的 探讨会阴切开时不同麻醉方式对产妇的影响.方法 将100例产妇随机分为左侧阴部神经阻滞麻醉组(阻滞组)和局部组织浸润麻醉组(浸润组),每组50例,比较两组产妇镇痛效果、缝合时间、第四产程出血量及产后72h活动的情况.结果 浸润组在镇痛效果、缝合时间、出血量及产后的活动方面均优于阻滞组.结论 在会阴切开缝合术中应用小剂量利多卡因作阴部浸润麻醉有效减轻了产妇的切口疼痛,缩短缝合时间,减少第四产程出血量.

虹膜夹型有晶状体眼人工晶状体植入术对高度近视眼对比敏感度的影响

目的 研究虹膜夹型有晶状体眼人工晶状体（iris-claw phakic intraocular lens，ICPIOL）植人术后对比敏感度（contrastsensitivity，CS）的变化。方法 2005年5月至12月于温州医学院附属眼视光医院和中山大学中山眼科中心接受ICPIOL（Verisyse，美国AMO公司）植入术的高度近视眼患者12例（23只眼），分别在术前、术后1、3、6个月采用CS测试灯箱（CSV-1000型，美国Vector Vision公司）检查暗视状态下无／有眩光时的对比敏感度函数（contrast sensitivity function，CSF）。结果 术后1、3、6个月等效球镜度数分别为（-0．60±0．77）D，（-0．48±0．77）D，（-0．34±0．53）D，与术前（-15．53D±3．65D）差异均有显著统计学意义（P均〈0．001），最佳矫正视力（IogMAR）分别为0．064-0．12，0．02±0．09，-0．003±0．08，与术前（0．21±0．12）差异均有显著统计学意义（P均〈0．001）。术后各空间频率的CS与术前比较有增高趋势。术后3个月6、12、18周／度的CS在无眩光时和有眩光时均明显提高（P均〈0．01），开始接近正常范围。术后3、6个月在各空间频率上CS差异均无统计学意义（P均〉0．05）。结论 ICPIOL植入术矫治高度近视眼可以使CSF恢复到接近正常范围，显著改善视功能，是一种适用于高度乃至超高度近视眼的可供选择的屈光手术。     

Sinoatrial Node Electrogram Studies in Patients with Sick Sinus Syndrome

Sinoatrial node electrogram (SNE) was recorded successfully in recent years, using transvenous electrode catheter. Via SNE and intratrialelectrogram (IEG), one could measure sinoatrial conduction time(SACT) directly, observe sinoatrial node (SN) potential changes in cadiac cycles, diagnose some sinus arrhythmias which couldn't be confirmed by surface ECG. All these could offer accurate evidence for differential diagnosis of sick sinus syndrome (SSS). The authors recommend a modified method for the location of the electrode catheter, by which one can increase success rate of obtaining stable SNE. Using this method, the authors recorded SNE in 10 cases with SSS successfully.     

两种方法解决介入治疗术后排尿困难效果的比较

冠状动脉造影术,使冠心病的诊断、治疗水平明显提高。但床上排尿困难是术后常见的护理问题,采用常规的方法,效果不佳,常需导尿术解决,既增加了患者的痛苦,又增加了护理工作量。我科2003年3月~2006年10月采取开塞露肛注刺激直肠诱发排便-排尿反射,较好地解决了床上排尿困难的问题。并与常规诱导排尿的方法进行了比较,现报告如下。临床资料对象选择冠状动脉造影术后排尿困难者60例,其中男性42例,女性18例,年龄20~78岁,平均53岁,随机分为对照组和观察组各30例,两组年龄、性别差异无显著性,具有可比性。方法(1)观察组:给予开塞露肛注排便以诱导…

Food and health at work–a review. The costs and benefits of a policy approach

The workplace is an important setting for health promotion and provides an ideal opportunity for shaping healthy eating patterns in occupational groups for whom inequalities have been identified (DHSS, 1980). Workplace food/health policies provide an intermediate and pragmatic step towards achieving the dietary targets set out in the Government's white paper Health of the Nation and the most recent COMA report (DoH, 1991,1992). Food/health policies have been widely adopted in the NHS (Gibson & Kallevik, 1990) and preliminary research suggests that they are an effective means of intervention (Wallis & Poulter, 1988; Frost et al., 1991). Industry has been slower to link food and health promotion to a policy making process. Surveys imply that action on healthy eating in companies often originates in the occupational health department and is based on individualistic approaches with little energy being put into preventive activities which would originate in the canteen (Mclnerney & Cooper, 1989; Poulter, 1990). Policies provide a means of balancing the environmental and educational paradigms of health promotion. If food/health policies are to grow in the private sector then industry has to be convinced that the benefits Justify the costs. Some philanthropic employers are motivated by interests other than financial gain, but others are commercially led. There is little hard evidence to demonstrate that any type of employer-sponsored healthy eating initiative provides a favourable return for investment. It has been ‘guesstimates’ and extrapolation from other situations which have provided the justification for UK companies to allocate any resources towards addressing food/health issues. In April 1990 the National Grid Company adopted a comprehensive food/health policy. This paper draws on the experiences in developing and implementing the policy document to discuss the issues around evaluative activity in a commercial setting. Views are expressed on the feasibility of measurement and the value of the informaton collected. One aim of the future should be to research this under-examined area to establish a solid body of information. This would raise the level of debate from one which is currently based on anecdotal evidence to a sounder scientific footing and, therefore, ensure the future growth of such policies in the corporate sector.
