目的建立基于江香薷有效基准特征图谱的质量表征模式、方法,以精准、有效地评价江香薷饮片质量。方法以确定有活血药效的江香薷饮片(饮片编号S5)作为有效饮片基准,以有效特征代表性成分及其含量作为质量表征基准点,采用HPLC-PDA建立其有效基准特征图谱,以对照品模拟基准点的有效基准特征图谱质量表征信息作为评价江香薷饮片有效质量基准标尺,并对其准确性进行佐证及质量评价应用与验证。结果以江香薷饮片S5(饮片基准)中有效特征代表性成分黄芩素-7-甲醚作为质量表征基准点,并以其对照品对基准点进行准确模拟(保留时间:61.020分钟、检测溶液含量:0.0115 mg/mL),分别对江香薷有效饮片S5(基准)进行质量表征,结果佐证了检测方法的可行性及检测结果的准确性。以模拟基准点为基准得到江香薷有效基准特征图谱质量表征信息:15个特征峰的相对保留时间、相对峰面积及7个特征代表性成分(咖啡酸、异迷迭香酸苷、野黄芩苷、迷迭香酸、黄芩素-7-甲醚、香荆芥酚、麝香草酚)含量、相对含量、含量换算系数等,作为评价江香薷饮片的质量基准标尺。其15个特征峰及其7个特征代表性成分涵盖了江香薷药学架构酚酸类、黄酮类、萜类三种主要化学类型,14批江香薷饮片的特征图谱中均含有15个共有特征峰,且基于含量换算系数得到的14批江香薷饮片中7个特征代表性成分的含量与实测含量基本一致;采用所构建的江香薷质量评价模式及其有效质量基准标尺,对14批江香薷饮片的质量进行评价得出:编号S13、S3、S8、S2、S1、S10、S12、S5(饮片基准)优良度居前。结论建立的基于江香薷有效基准特征图谱质量表征模式与评价方法,可简易、准确、整体地对江香薷饮片进行质量表征与评价,为江香薷饮片的精准质量评价与有效应用提供科学依据,亦为其他中药的质量表征与评价提供借鉴。

针刺效应是如何启动的,是针刺作用原理研究中的共性关键问题。多年来在肯定针刺效应的前提下,从穴位局部化学离子入手,由点及线,由线成网,从神经、免疫、内分泌、能量代谢不同角度开展研究,探讨了局部神经-细胞-化学物质的相互作用,系统研究了针刺后“穴网络”变化其与针刺效应的关系,证实:1)针刺可引起支配穴位的神经兴奋,启动神经调节;2)针刺可引发穴位局部炎性反应,启动免疫调节;3)针刺可调节穴区部分激素水平;4)针刺可调节穴区血流和氧分压,影响局部能量代谢;5)针刺后穴区神经-肥大细胞-化学物质相互作用,影响针刺效应;6)有向加权模型和复杂网络模型能够刻画针效初始调控网络的时序响应特征,并发现其中关键节点。对针效启动机制的研究,应将局部反应与整体效应相结合,建立起相互联系、相互影响的复杂网络概念,进行系统的归纳和规律的提炼,从而揭示针效启动的关键基础因素,探寻针刺效应的有效调控模式,提高针刺的临床疗效。
