基于药性组合的归肺经药理作用特征研究

目的：药性是中药的基本属性,药性理论是中药组方配伍的核心理论依据。该文通过药性组合探讨归经中药的药理作用特征,目的在于将药性配伍规律引入到复方药的设计与优化过程,发挥药性理论在组方配伍中的指导作用。方法：以代表性归经"肺经"为例,收集整理2010年版药典中归肺经中药药性组合。利用“中国期刊全文数据库”(CNKI)检索,收集1980年以来国内公开发表的有关上述中药的全部药理研究文献,并参考《中药学》、《临床中药学》对其药理信息进行补充。利用关联规则方法挖掘归肺经中药的药性和药理作用之间的关联关系。结果：不同性味的归肺经中药在药理作用上存在明显差异,例如,平甘肺能降血糖、抗缺氧、免疫促进;平苦肺能够抗菌、降血压、抗氧化;温甘肺能够镇咳、抗菌;温苦肺能祛痰、抗炎等。同时,归肺经中药也具有相似的药理特征,例如抗菌、抗炎,与肺为门户易感外邪的特点相一致。结论：该研究发现了不同性味归肺经中药的药理作用特征,连通了中药传统理论与现代研究成果,为建立符合中医药思想的中药药性组方体系打下基础。

Study on characteristics of pharmacological effects of traditional Chinese medicines distributing along lung meridian based on medicinal property combination

Objective: Medicinal properties are the basic attribute of traditional Chinese medicines(TCM), while the medicinal property theory is the core theoretical foundation of TCM formula combination. In this particle, authors studied the characteristics of pharmacological effects of property combination of traditional Chinese medicines distributing along meridians, with the aim to introduce the medicinal property combination regularity into the design and optimization process of compound TCMs, and bring the medicinal property theory into full play in guiding the formula combination.Method: In this paper, TCMs distributing along "the lung meridian" was taken for example. The medicinal property combinations of TCMs distributing along "the lung meridian" recorded in Pharmacopeia (2010) was collected and processed. Besides, Chinese journal full-text database (CNKI) was used to collect all of pharmacological study literatures concerning the above TCMs that have been published since 1980. the pharmacological information was also supplemented by reference to Science of Chinese Materia Medica and Clinical Science of Chinese Materia Medica.Result: TCMs distributing along the lung meridian with different properties and tastes showed significant differences in pharmacological effects. For example, mild-sweet-lung medicines could lower blood sugar levels, decrease anoxia and enhance immunity; Mild-bitter-lung medicines showed anti-bacterial, anti-hypertension, anti-oxidation effects; Hot-sweet-lung medicines showed antibechic and anti-bacterial effects. And Hot-bitter-lung medicines showed phlegm eliminating and anti-inflammatory effects. Meanwhile, TCMs distributing along the lung meridian had similar pharmacological characteristics, such as anti-bacterial and anti-inflammatory effects, which is consistent with lung's feature in susceptibility to exogenous pathogenic factors.Conclusion: In this study, authors discovered pharmacological characteristics of different TCMs distributing along the lung meridian, which links TCM theory with modern study achievements and lays a foundation for establishing a TCM property formula combination system.
