蒲地蓝消炎口服液联合氢定乳膏治疗PICC局部湿疹临床观察

目的观察蒲地蓝消炎口服液联合应用氢定乳膏治疗PICC局部湿疹的疗效。方法采用病例对照研究的方法,选择PICC门诊2014年1月-2018年12月PICC局部湿疹患者80例,随机分为实验组39例和对照组41例,观察组用蒲地蓝消炎口服液联合氢定乳膏加局部敷料开窗法进行护理。对照组用氢定乳膏加局部敷料开窗法,比较2组的临床疗效。结果观察组39例,总有效34例(87.18%);对照组41例,总有效23例(56.10%)。2组比较差异具有统计学意义(P<0.01)。结论蒲地蓝消炎口服液联合氢定乳膏治疗PICC局部湿疹的效果优于对照组。     

截断逆挽方含药血清对D-氨基半乳糖诱导的人正常肝细胞LO2细胞增殖影响

目的研究截断逆挽方含药血清通过调控E2F1介导的细胞增殖途径减轻D-氨基半乳糖(D-Galactosamine,D-GlaN)诱导的人正常肝细胞LO2的损伤。方法体外培养LO2细胞,以D-GlaN进行造模,将细胞分为正常组、模型组、2.5%截断逆挽方含药血清组(2.5%JDNWF)、5%截断逆挽方含药血清组(5%JDNWF)、10%截断逆挽方含药血清组(10%JDNWF)。采用Cell Counting Kit-8(CCK8)法检测细胞活力;Real-time PCR检测转录因子E2F1、细胞周期蛋白E(cyclin E)、细胞周期蛋白A(cyclin A)、细胞周期蛋白依赖性激酶2(cyclin-dependent kinase 2,CDK2)、细胞分裂周期因子25A(cell division cyclin 25A,CDC25A)mRNA的表达;流式细胞术检测细胞周期;Western Blot检测分化调控因子DP1蛋白表达。结果截断逆挽方含药血清能显著促进LO2细胞进入S期(P<0.01),上调E2F1、cyclin E、cyclin A、CDK2、CDC25A mRNA的表达(P<0.01),并且能增加DP1蛋白的表达(P<0.05,P<0.01)。结论截断逆挽方减轻肝细胞损伤的作用机制可能与其促进肝细胞增殖有关。     

Formulación magistral en pacientes con genodermatosis. Impacto en la calidad de vida: un estudio transversal

BackgroundCutaneous manifestations are complicated to treat in rare diseases. The main aim of this study was to analyze the impact of compounded drugs prepared by hospital pharmacists on the quality of life of patients with genodermatoses.Material and methodsWe undertook a cross-sectional study of patients with genodermatoses treated with topical medications compounded and dispensed by the pharmacy at Complejo Hospitalario Universitario in Pontevedra, Spain. We collected demographic data and answers to questionnaires examining generic and disease-specific quality of life, treatment satisfaction, and treatment adherence.ResultsNine patients were included. We observed a significant improvement in health-related quality of life following treatment with compounded drugs. Satisfaction with the topical medications was 2.8 on a scale of 0 (greatest satisfaction) to 25. Treatment adherence was 59%.ConclusionsDrug compounding facilitates access to orphan drugs that are not available for many rare diseases. Few studies, however, have analyzed impact on quality of life in this setting. In this series of patients with genodermatoses, topical medications compounded and dispensed by a hospital pharmacy improved health-related quality of life. This preliminary study has given rise to a multicenter study of compounding for ichthyosis. We expect that analysis of a larger sample will confirm our findings.     

《备急千金要方》腑实热病证组方配伍用药特色初探

《备急千金要方》集中体现了唐代初期以前的医学成就,具有很高的临床价值,首开脏腑论治先河,脏腑卷下分列虚实,提示辨证法门,方药罗列其中,以方示法。《备急千金要方》腑实热内容,以寸口脉位定脏腑,以阳实脉象示病性,以关联经脉及脏腑病症为提纲,以热邪充斥,经腑、脏腑同病为病理特征。依据各腑实热的病理特点,结合《千金翼方》本草理论,分析其组方用药特色,随腑实热病性不同有清养、清泻、清宣、清解等功效,视其兼证而用安神、泻下、利水、行气、凉血,解毒散结等药物。其组方配伍思路既可以针对现代疾病如不寐、头痛、乳痈、口疮、便秘、癃闭等提供借鉴,也可为临床新药开发提供方源和创新思路。     

水分去除的方法及其在药物合成中的应用

化学药合成过程中水分残留不利于反应的进行,还影响药物及制剂的稳定性、理化性质、溶出及药理作用等,因此水分几乎是大多数药物合成中的必测项目,通过有效除水严格控制反应体系中水分的含量至关重要。本文综述了水分的存在形式,常见除水剂和脱水剂的种类、作用原理与除水能力,以及在药物合成的应用,为药物合成反应中水分的去除提供参考。
