Ara h 2是花生主要过敏原之一,为开发食物中Ara h 2过敏原成分的快速检测方法,减少因误食导致花生过敏事件的发生,该研究采用鼠源单克隆抗体作为捕获抗体、兔源多克隆抗体作为检测抗体,通过棋盘法优化抗体工作浓度,建立了一种检测花生...Ara h 2是花生主要过敏原之一,为开发食物中Ara h 2过敏原成分的快速检测方法,减少因误食导致花生过敏事件的发生,该研究采用鼠源单克隆抗体作为捕获抗体、兔源多克隆抗体作为检测抗体,通过棋盘法优化抗体工作浓度,建立了一种检测花生过敏原Ara h 2的间接双抗夹心化学发光酶免疫分析法,并对该方法的灵敏度、准确度、精密度和特异性进行评价。该方法的检出限为1.085 ng/mL,线性范围为3.12~200 ng/mL,添加回收率为78.30%~94.39%,批内和批间变异系数均小于10%,且特异性良好,与其他常见食物过敏原无交叉反应。该方法与相同抗体所建立的间接双抗夹心酶联免疫吸附测定(enzyme-linked immunosorbent assay, ELISA)方法相比,在灵敏度上表现出一定优势。该研究开发的化学发光酶免疫分析法可对花生食品生产过程中和消费前的Ara h 2过敏原成分检测提供可靠的技术支持。展开更多
目的:探究规范化H2H(Hospital To Home)营养管理模式在鼾症患儿加速康复中的应用效果。方法:便利选取云南省某三级综合医院儿科住院手术的92例鼾症患儿为研究对象,随机将其分为对照组和研究组,各46例。对照组予以常规营养管理模式,研究...目的:探究规范化H2H(Hospital To Home)营养管理模式在鼾症患儿加速康复中的应用效果。方法:便利选取云南省某三级综合医院儿科住院手术的92例鼾症患儿为研究对象,随机将其分为对照组和研究组,各46例。对照组予以常规营养管理模式,研究组予以规范化H2H营养管理模式,对比两组患儿的营养状况及护理满意度。结果:研究组较对照组的营养状况好,护理满意度评分高(P<0.05)。结论:在鼾症患儿手术治疗后的加速康复护理中,运用规范化H2H营养管理模式,可使患儿获得个体化、针对性的营养护理指导,使得患儿的体格发育和营养状况得到较大的改善,有利于患儿的身心健康,同时可获得较好的护理满意度,值得进一步推广应用。展开更多
