To prepare antimicrobial bamboo fabric by oxidization method and the research of related properties [PDF]
, 2016 根据相关文献和世界卫生组织报告，目前在世界范围内仍然有多于8.8亿的人口不能获得安全、卫生的饮用水源，这一情况主要集中在不发达地区。到目前为止，世界上每年仍有大约220万人死于饮用不卫生水导致的痢疾等其他疾病，这其中大部分是儿童。造成这一问题的主要原因是缺乏安全可靠、廉价的水处理技术。 大量文献表明，磺胺嘧啶银对皮肤烧伤、溃疡等伤口处易感染细菌具有较好的杀灭效果，可对伤口化脓及感染情况进行有效控制。但是磺胺嘧啶银及其他低浓度银盐对体液或者水不具有耐受性，极容易流失，使得其使用范围受到一定的限制。研究发现，

Screening and application of aptamers to Staphylococcus aureus Toxic Shock Syndrome Toxin-1 [PDF]
, 2016 摘要 目的：金黄色葡萄球菌(Staphylococcusaureus)分泌的毒性休克综合征毒素-1(ToxicShockSyndromeToxin-1，TSST-1)引发中毒性休克综合征(ToxicShockSyndrome，TSS)，通过激活T淋巴细胞使其活化、增殖，引起强烈的免疫应答。目前针对TSST-1本身的治疗手段不多，合成寡核苷酸文库和亲和力筛选作为获得高亲和力、高特异性适配体(Aptamer)的一种方便、快捷、有效的方法。本研究利用指数富集的配体系统进化技术 ...

Study on Rapid Detection System and Molecular Epidemiology of Staphylococcus aureus [PDF]
, 2017 金黄色葡萄球菌（Staphylococcusaureus，S.aureus）作为医院感染中常见的致病菌之一，往往可引起皮肤软组织感染、肺炎、尿路感染等疾病，但也时常导致危及生命的血流感染、心内膜炎、中毒休克综合征等，造成了诊疗费用的增加和医疗资源的浪费。而甲氧西林耐药的S.aureus（Methicillin-resistantStaphylococcusaureus，MRSA）更是增加了对该病原菌感染防治的难度。因此，如何快速并准确地检测并鉴定病原菌，掌握其流行规律和耐药情况 ...
