简介：摘要ICU患者是压疮的高危人群，一旦压疮发生不仅增加患者的风险，更容易导致医疗资源的浪费。本科通过3M透明敷贴在50例压疮高危因素评分均≤16分患者的预防性护理中的使用，取得了良好的效果。

简介：[目的]探讨快速、便捷的船舶压舱水卫生学指标检测方法，为制定有效的入境船舶压舱水卫生监管措施，保护我国水域卫生安全提供可靠的依据。[方法]用3Mpetrifilm^[TM]细菌总数测试片和大肠菌群测试片对入境船舶压舱水样品进行检测。用国家标准《大肠菌群和粪大肠菌群证实实验》（GB／T4789．3—2003）进行验证。[结果]52份来自韩国和日本入境船舶压舱水中细菌总数超过2000个／ml的14份，占检测总数的26．9％；大肠菌群阳性的2份，阳性率3．9％。[结论]用3M微生物测试片对入境压舱水进行检测，细菌总数测试片使用方便，易于计数，能反应每毫升压舱水中真实的细菌总数；普通大肠菌群测试片，大肠菌群易于辨认和计数，但与我国现行方法比较，其加样量小，可能存在较多的漏检情况，建议使用滤膜过滤方法。

简介：目的探讨腺病毒介导的野生型p53在前列腺癌基因治疗中的可能性及其机制.方法培养前列腺癌细胞系PC3M,转染腺病毒介导的野生型p53,检测其增殖和凋亡水平变化,并检测其bax蛋白及mRNA水平.结果腺病毒介导的野生型p53可高水平地转染入PC3M细胞,转染后的PC3M细胞增殖受到抑制、凋亡水平增高,细胞中bax蛋白及mRNA水平皆增高.结论腺病毒介导的野生型p53可抑制PC3M细胞增殖并促进其细胞凋亡.其促进凋亡的机制可能是通过促进bax表达而实现的.

简介：目的对2HRZE/4H3R3和2H3R3Z3E3／4H3R3治疗初治涂阳肺结核病患者社会效果评价，为结核病的社会控制提供依据。方法应用中国卫生部结核病控制项目2HRZE/4H3R3方案，治疗初治涂阳肺结核病人的监测资料和2003年对《中国结核病控制规划(2001—2010)))阶段评估，抽查“世界银行贷款+中国结核病控制项目”2H3R3Z3E3/4H3R3方案治疗初治涂阳肺结核病人治疗的资料进行分析。结果在落实较好的全程督导服药治疗下，两方案已达到国家规划目标。目前2H3R3Z3E3/4H3R3未能达到国家规划目标，治愈率明显较强化期每日服药方案低，而失败率、丢失率、副反应停药率明显较高。结论经费落实不到位导致患者全程督导服药治疗不能很好落实，是影响化疗效果的主要原因。由于全程督导服药治疗不能很好落实，致使全程隔日服药方案不能胜任规划目标的要求，提示结核病控制的方向。

简介：抗人球蛋白试验(AHG)被视为检测免疫性抗体的一种经典方法,特别对免疫性溶血性输血反应和新生儿溶血病病因的诊断十分有益.随着免疫血液学技术的发展,检测免疫性抗体方法也逐渐增多.新近,国外推出一种新的方法即磁珠固定被动血凝试验[1](M-MPHA),该方法具有简便、敏感的特点.为此,笔者应用该方法检测了109份多次输血患者的血清标本,并与AHG法进行Rh抗体敏感度的比较.现将结果报告如下.
