目的:构建《四部医典》方剂数据库,挖掘其用药规律,为研究藏族医学(简称藏医)用药规律提供参考。方法:收集《四部医典》中《秘诀医典》和《后续医典》记载的方剂,应用Visual Fox Pro 9. 0构建方剂数据库,结合藏医疾病的'十五会'...目的:构建《四部医典》方剂数据库,挖掘其用药规律,为研究藏族医学(简称藏医)用药规律提供参考。方法:收集《四部医典》中《秘诀医典》和《后续医典》记载的方剂,应用Visual Fox Pro 9. 0构建方剂数据库,结合藏医疾病的'十五会'及其治疗的'十八实践'双视角,应用Gephi 0. 9. 2复杂网络等方法进行分析。结果:《四部医典》共收载2 695首藏药方剂,构成每一方剂的药味均数为6. 6味,其中≤7的占总方剂的69. 2%,总方剂涉及的药物有1 002种,其中诃子、竺黄、红花、荜茇、干姜等节点度≥156,藏医特色药食两用药物酥油、白糖、青稞甜醅、蜂蜜、红糖等节点度≥91,根据十五会(skabs bco lnga)的疾病分类,伤科病会有495首方剂、热病会有323首、毒症会有278首、三因病会有197首等。根据十八实践(lag len bco brgyad)治疗方法,散剂有162首,汤剂有77首,催泻法有84首等。关联规则分析发现冰片、竺黄、红花、檀香等凉性药物的边权重≥59,石榴子、荜茇、肉桂、豆蔻等温性药物的边权重≥45。结论:《四部医典》具有以'凉-温'药性为双核心的椭圆式哲学用药规律,以'消-泻'(zhi-sbyong)二法为用药方法,隆-赤巴-培根的权重为用药辨证思维等特点,其中酥油、青稞甜醅、白糖等藏医特色送服剂的临床应用突出,体现了以整体平衡为重心的藏族文化哲学思想,具有'食疗加药物,药物加治法'的多维立体用药规律,对揭示藏医用药规律的研究具有积极意义。展开更多
