Nucleophosmin/B23 (NPM) is a nuclear protein with prosurvival and ribosomal RNA processing functions.However,the potential role of NPM involved in drug-resistance in leukemia hasnt been investigated clearly.In this study,we generated an adriamycin (ADM)-resistant lymphoblastic cell line Molt-4/ADR (MAR).Cell proliferation,sensitivity to chemotherapy agents and expressions of drug resistance related molecules were assessed.The IC50 of Molt-4 cells were 0.186±0.019umol/L and of MAR cells were 3.83±0.381 umol/L,meaning MAR cells were 38.63 fold resistant to Molt-4 cells.Furthermore,MAR cells gained an expression of mdr-1(P-gp) and a higher expressionof NPM compared to Molt-4 cells.

目的:探讨无损伤针不同进针角度对输液港维护的体会。方法:对30 例植入输液港的患者静脉维护180 次,使用两种不同进针方法进行维护。维护时随机抽取,实验组90 人次采用进针时无损伤针斜面朝向胸骨柄,且斜面与港口形成90 度角,抽到回血后再将无损伤针向下回转90 度,使无损伤针斜面与港口背对;对照组90人次采用常规方法,进针时无损伤针斜面与脐水平,即无损伤针斜面与港口背对。结果:实验组的这种进针方式
研究目的:探討人形圖教學模式用於培育「以病人為中心」護理過程之成效.研究方法:採議題式訪談,以曾使用人形圖(Figure Maps)進行案例分析的護理師為研究對象,瞭解其報告前後的思維轉變,以及是否有助於護理過程的邏輯思維,共訪問21位護理人員,共計22次訪談,每次時間約1至1.5小時.研究嚴謹度採用Lincoln和Guba(1985)所提的信任準則:確實性(credibility)、可轉換性(t
