The most characteristic feature of Traditional Chinese Medicine (TCM) and Materia Medica (TCMM) is the holistic concepts in disease diagnosis and treatment. Each medicine has its own holistic preferences, i.e. "properties, tastes and meridian distribution". On the other sides, TCM and TCMM also distinguish from modern medicine by their personalized therapeutic strategies. Clearly, the philosophical basis of TCM and TCMM is the integration of holism with specificity, and therefore, the quality assessment of TCMM should also follow this philosophical basis. In this proposal, we hypothesize that the quality of TCMM is a relative concept which depends on a specific pharmacological effect or therapeutic purpose. We use a case study of Schisandra chinensis to test the hypothesis by introducing multivariate analyses of PLS, PCA and PLS-DA to the quality assessment of TCMM. Multivariate analyses allow recognition and identification of the biomarkers that actually contribute to the specific pharmacological effect, i.e. the protective effect of S. chinensis against CCl4 hepatotoxicity in rats. In order to integrate the multiple biomarkers, we defined a Holistic Quality Index (HQI) with which a PLS regression model will finally be built for predicting the HQI value of a given test sample. The HQI therefore unites the opposites of holism of quality and specificity of pharmacological effect. The significance of this study is profound both in the innovation in quality analysis of TCMM and in the understanding of the potential coupling relations among different components in them. Furthermore, it will also throw some lights on the concepts of the functions, tastes, safety and mechanism of medication of TCMM.
中医药学的主要特征是强调机体整体性,但在整体辨证之后给出的却是个性化的治疗方案,这体现了整体性与特异性的对立和统一。在中医理论体系指导下的中药同样具有整体性的性味与归经属性,但在不同配伍中却常常发挥不同的功效,同样体现了整体性和治疗目的特异性的对立与统一。在此辩证哲学基础上,我们认为中药质量水平并非一个绝对的概念,具有很大的治疗目的依赖性,即中药的质量评价也应遵循其上述整体性和特异性相结合的原则。我们以北五味子为研究实例来验证上述思路:针对其典型的保肝活性,采用基于多变量分析的模式识别方法,从可能影响药材质量的多维变量体系中识别出真正对五味子保肝功效产生矢量贡献的生物标志物,最后通过整体性质量指数(HQI)整合这些生物标志物,并建立基于保肝功效的HQI评价模型。本研究依据中医药的哲学基础,提出了中药的药效依赖性综合质量评价思路,对于探索创新性中药质量评价方法具有一定的科学意义。
中医学作为中国文化的表现形式之一,是一个以强调机体整体性为主要特征的医学体系,在中医理论体系指导下使用的中药,其特点具有整体性的性味与归经属性,但在不同配伍中却常常发挥不同的功效,这体现了整体性与特异性的对立和统一。基于这种辩证哲学基础,我们认为中药的质量水平在很大程度上并非一个绝对的概念,它具有很大的治疗目的或功效依赖性,也就是说对中药质量水平的定量必然关联某一特定的功效。因此,中药的质量评价也应遵循其上述整体性和特异性相结合原则。北五味子是辽宁省道地药材,其化学成分和药理活性研究透彻,因此,我们选择该药材作为研究对象来验证以上的研究思路,针对其典型的保肝活性,采用基于多变量分析的模式识别方法,从可能影响药材质量的多维变量体系中识别出真正对五味子保肝功效产生矢量贡献的生物标志物,并建立基于保肝功效的HQI评价模型。对于探索创新性中药质量评价方法具有一定的科学意义,还有助于进一步理解中药有效性、安全性及可能的作用机制。
