尽管万古霉素对甲氧西林耐药金葡菌(MRSA)在体外仍保持较好的抑菌活性,但临床医师开始质疑是否应该继续应用万古霉素治疗MRSA引起的感染.很多研究表明万古霉素对 MRSA的MIC已高达CLSI 的敏感性范围的上限2 mg/L.

ICP仪器正日益增长地广泛应用于非水溶液的分析。即使ICP样品引入系统对某类样品要求稀释,光度计灵敏度也能很好地满足大多数分析的需要。ICP原子荧光光度计是由高温原子化池(ICP)与分光技术组合而成,以避免谱线干扰及基线飘移。在此研究中,应用于收集数据的AFS-2000型仪器是常规用于测定各种水溶液介质中痕量元素的。为了将所操作的水溶液转换为有机溶液,样品引入系统须用乙醇清洗。

ICP-AES很适于各式各样材料的分析,因为它具有很高的样品承受能力、很宽的动态线性范围和很好的灵敏度。但是,传统的采用雾化器的样品引入技术(常被称为“最薄弱环节”)往往会大大地降低灵敏度而限制该系统的性能。某些组分有优先雾化现象因而会使分析结果不准确。另外,在许多情况下,由于化合物的挥发性、毒性和可燃性又会使取样发生困难。本文叙述用VFS快速获得数据系统和ICP作水溶液和半导体材料分析的情况。半导体工业已越来越要求对制造过程所用材料中越来越低的杂质水平加以表征。VFS是一种可作瞬时信号测量和专门数据处理和报告的硬件/软件系统。由于不用雾化器而采用了全新的样品引入技术,方法的灵敏度和分析性能都得到了改善。系统可以每秒钟积分6次的速率对最多60种元素作同时测量。

BACKGROUND: There are over 15 million children who have cardiac anomalies around the world, resulting in a significant morbidity and mortality. Early recognition and treatment can improve the outcomes and lengthen life-expectancy of these patients. The NIH and WHO have promoted guidelines for screening for congenital cardiac anomalies using ultrasound in rural ***: Our study took place in Bocas Del Toro, Panama where a mobile clinic was established for community healthcare screening and ultrasonographic evaluation by medical student volunteers and volunteer clinical faculty. This was a non-blinded, investigational study utilizing a convenience sample of pediatric patients presenting for voluntary evaluation. Seven first-year medical students were recruited for the study. These students underwent a training program for advanced cardiac ultrasound instruction, termed "Pediatric Echocardiography Cardiac Screening(PECS)".RESULTS: Ten patients were enrolled in the study. Nine patients had adequate images as defined by the PECS criteria and were all classified as normal cardiac pathology by the medical students, resulting in a sensitivity and specificity of 100%. A single patient was identified by medical students as having a pathologic pulmonic stenosis. This was confirmed as correct by a blinded ***: In this pilot study, the first-year medical students were able to correctly identify pediatric cardiac anatomy and pathology in rural Panama after undergoing a 12-hour ultrasound PECS training session. We believe that with this knowledge, minimally trained practitioners can be used to screen for cardiac anomalies in rural Panama using ultrasound.
