purpose: based on a series of 3,4-seco or closed ring lanostane triterpenoids with similar structures separated from the medicinal material Poria cocos (Schw.) Wolf and in combination of the spectrum data regarding other lanostane triterpenoids of Poria cocos reported in literatures, comparisons are made to the data regarding the ultraviolet spectrum, infrared spectrum, circular dichroism spectrum,mass spectrum and NMR spectrum of lanostane triterpenoids so as to provide a reference basis for the structure analysis of this type of compounds.Method: the spectroscopic characteristic laws are analyzed and concluded through comparison of spectrum data and based on data reported in literatures.Result: nearly forty 3, 4-seco or closed ring lanostane triterpenoids with similar structures have been obtained with their spectrum data sorted out and concluded.Conclusions: spectroscopic characteristics of lanostane triterpenoids are summarized to be used as the reference for analyzing the structure of these compounds.

"内不治喘",哮喘自古以来就属于呼吸系统疾病的顽症,古代医家对该病有详尽的论述及记载,本文通过总结古今医家对哮喘的认识,粗略探析其辩证思路.中医认为本病病机为本虚标实,其主要致病因素在于痰、邪、虚、瘀四方面.治疗上针对哮喘的不同发病阶段,根据"急则治其标,缓则治其本"的原则,采取治哮先祛痰、发作期解表散寒温肺化饮、缓解期当扶正固本、活血化瘀贯通全程等治疗大法,从而改善患者的临床症状及减少发作频次.
目的：本文对维药药桑椹果(SHATUT)对常见细菌的药物敏感性进行试验研究.方法：采用抑菌试验滤纸片法和MIC试验方法对药桑椹各类原液、煎煮液和提取液进行抑菌试验.结果：本实验研究揭示,维药药桑椹对革兰氏阳性球菌和革兰氏阴性杆菌(铜绿假单胞菌)等化脓性细菌具有较强的抗菌抑菌作用.同时还观察到药桑圣果不仅对以上化脓性感染有作用,且对耐青霉素金黄色葡萄球菌、耐青霉素肺炎链球菌、流感嗜血杆菌、大肠杆菌、
目的：通过观察清金化痰汤对慢性阻塞性肺疾病气模型大鼠EGFR/MAPK信号转导通路的影响,探索清金化痰汤对慢性阻塞性肺疾病气道粘液高分泌的作用机制.方法：40只清洁级Wistar大鼠随机分为空白对照组(A)、模型组(B)、清金化痰汤组(C)、克拉霉素组(D).B、C、D组大鼠给与气管内滴注LPS联合烟熏的方法建立慢性阻塞性肺疾病气道粘液高分泌模型.B组、C组、D组连续30天分别给予生理盐水、清金化

As modem medical methods advance, it becomes more apparent that our new technologiesare allowing us to better appreciate the wisdom of traditional medical practices that have a closer relation to natu
京尼萨克在成书于公元8世纪的《四部医典》中有着较为全面的记载,类似于西医的糖尿病,为了更好地指导藏医临床诊疗,对京尼萨克的病因病机作了较为深入的探讨,归纳为其疾病内因是培根,外因是过食咸甘二味、过多摄入凉重二性、久居潮湿之地和久卧安逸.病机为培根偏盛、胃火下降、脂肪沉积、赤巴紊乱、隆偏盛5个阶段.其中,培根偏盛所致的脂肪代谢紊乱和赤巴偏盛引发的热证是最主要的两个阶段.培根偏盛是根源,胃火下降是核心
传统医药是我国劳动人民智慧的结晶,是我国优秀文化的重要代表.云南省积极发起并参与大湄公河次区域传统医药交流会,经过多年的探索的实践,将其打造成为次区域六国开展传统医药学术交流的重要平台.在"一带一路"的战略背景下,充分发挥这个学术平台的作用,对服务"一带一路"的战略需要,传承和发展中国传统医药具有重要的现实意义.
目的:评价柴朴制剂对哮喘治疗的临床疗效.方法:使用文献搜索引擎中国生物医学文献数据库(CBM)、万方数据库、中国知网(CNKI)、维普数据库、PubMed对柴朴制剂治疗哮喘的文献进行搜索,然后进行meta分析.结果:共纳入6篇RCT论文合计422名患者,meta分析结果显示:试验组(柴朴试剂联合常规治疗)与对照组(常规治疗)相比总有效率差异有统计学意义[OR=4.78,95％CI (2.300,9
