Histamine H1-receptor antagonists are effective in chronic as well as acute urticaria. When H1-anti-histamines are ineffective, add-on use of H2-receptor antagonists is thought to give better symptom relief. However, there are few reports on the therapeutic efficacy in pediatric patients. We retrospectively reviewed the medical records of pediatric patients with chronic spontaneous urticaria (csU) who met the following criteria. They were consulted our outpatient clinic between April 2010 and March 2012;were unsuccessfully treated with H1 antihistamines;and were treated with add-on H2-receptor antagonist (famotidine). In six patients who met the inclusion criteria (mean age 6.1 ± 5.1 years), urticaria activity score was significantly decreased from 4.3 ± 0.8 just before administration of famotidine to 1.3 ± 1.0 on the first outpatient visit within 4 weeks after the first administration of famotidine展开更多
建立了一种在温和条件下,用可见光催化合成一系列3,4-二氢异喹啉-1(2H)-酮及其衍生物的方法。该方法在室温条件下,以2-烯丙基-N-甲氧基苯甲酰胺为模板底物,以碘化钾作为光催化剂,25 W 460 nm的蓝色LED灯照射下,合成一系列3,4-二氢异喹啉...建立了一种在温和条件下,用可见光催化合成一系列3,4-二氢异喹啉-1(2H)-酮及其衍生物的方法。该方法在室温条件下,以2-烯丙基-N-甲氧基苯甲酰胺为模板底物,以碘化钾作为光催化剂,25 W 460 nm的蓝色LED灯照射下,合成一系列3,4-二氢异喹啉-1(2H)-酮衍生物,最高产率可达到83%。该合成路径具有底物适用范围广、经济实用等特点,为3,4-二氢异喹啉-1(2H)-酮衍生物合成提供了一种经济简便的方法。展开更多
为建立花生致敏蛋白Ara h 2双抗夹心酶联免疫吸附试验(ELISA)检测方法,本研究基于所制备的抗体,采用双抗体夹心检测模式,以Ara h 2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,并通过棋盘法优化抗体工作浓度,对该方法的灵...为建立花生致敏蛋白Ara h 2双抗夹心酶联免疫吸附试验(ELISA)检测方法,本研究基于所制备的抗体,采用双抗体夹心检测模式,以Ara h 2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,并通过棋盘法优化抗体工作浓度,对该方法的灵敏度、准确度、精密度和特异性进行鉴定。结果表明,建立的双抗夹心ELISA检测方法对Ara h 2的检出限为5.04 ng·mL^(-1),线性范围为15.63~1 000 ng·mL^(-1),添加回收率为80.12%~96.03%,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。本研究可为致敏蛋白Ara h 2检测提供一种快速高效的方法。展开更多
