    Abstract:
    This study aims to explore the core connotation of the compatibility of Aconiti Lateralis Radix Praeparata(Fuzi)-Glycyrrhizae Radix et Rhizoma(Gancao) herb pair under physiological and pathological conditions. The biochemical indicators of serum/myocardial tissue, pathological changes of the myocardial tissue, and serum metabolic profiles of normal rats and heart failure model rats treated with Fuzi Decoction and Fuzi Gancao Decoction were determined. Network pharmacology and metabolomics were employed to establish the metabolite-target-pathway network for Glycyrrhizae Radix et Rhizoma in enhancing the efficacy and reducing the toxicity of Aconiti Lateralis Radix Praeparata, Western blotting was employed to verify the representative pathways in the network. The results showed that both decoctions lowered the levels of creatine kinase and other indicators and mitigate myocardial pathological injury in model rats. However, they caused the abnormal rises in creatine kinase and other indicators and myocardial pathological injury in normal rats. The results indicated that the compatibility reduced the toxicity in normal rats and enhanced the efficacy in model rats. The results of metabolomics showed that Fuzi Gancao Decoction recovered more metabolites in model rats and had weaker effect on interfe-ring with the metabolites in normal rats than Fuzi Decoction. The association analysis showed that the network of Glycyrrhizae Radix et Rhizoma enhancing the efficacy of Aconiti Lateralis Radix Praeparata involved 112 metabolites, 89 targets, and 15 pathways, including calcium and cAMP signaling pathways. The network of Glycyrrhizae Radix et Rhizoma reducing the cardiotoxicity of Aconiti Lateralis Radix Praeparata involved 36 metabolites, 59 targets, and 11 pathways, including adrenergic signaling and tricarboxylic acid cycle in cardiomyocytes. The experimental results of protein expression verified the reliability of the association analysis. This study demonstrated that the core connotation of the herb pair of Aconiti Lateralis Radix Praeparata-Glycyrrhizae Radix et Rhizoma changed under physio-logical and pathological states, and the compatibility results of enhancing efficacy and reducing toxicity were achieved with different metabolic pathways and biological processes.
