RESUMEN
INTRODUCTION: Yerba mate is widely consumed in South American countries and is gaining popularity around the world. Long-term consumption of yerba mate has been proven to have health-care functions and therapeutic effects on many diseases; however, its underlying mechanism has not been clearly elucidated. In this research, we explored the pharmacological mechanism of yerba mate through a network pharmacological approach. MATERIAL AND METHODS: The bioactive components of yerba mate were screened from published literature and the Traditional Chinese Medicine System Pharmacology Database (TCMSP), and the targets and related diseases were retrieved by TCMSP. Furthermore, the component-target-disease network an protein-protein interaction (PPI) network were constructed, and combined with gene ontology (GO) functional analysis and Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway enrichment analysis to explore the pharmacological mechanism of yerba mate. RESULTS: As a result, 16 bioactive components of yerba mate were identified, which acted on 229 targets in total. Yerba mate can be used to treat 305 diseases, such as breast cancer, asthma, Alzheimer's disease, osteoarthritis, diabetes mellitus, atherosclerosis, and obesity. Protein kinase B (AKT1), signal transducer and activator of transcription 3 (STAT3), mitogen-activated protein kinase 1 (MAPK1), transcription factor AP-1 (JUN), cellular tumour antigen (p53) TP53, tumour necrosis factor (TNF), transcription factor p65 (RELA), interleukin-6 (IL6), amyloid-beta precursor protein (APP), and vascular endothelial growth factor A (VEGFA) were identified as the key targets of yerba mate playing pharmacological roles. The signalling pathways identified by KEGG pathway enrichment analysis that were most closely related to the effects of yerba mate included pathways in cancer, fluid shear stress and atherosclerosis, and human cytomegalovirus infection. CONCLUSION: the results of our study preliminarily verify the basic pharmacological action and possible mechanism of yerba mate and provide a reference for the further development of its medicinal value.

Background: Cordyceps is a precious Chinese herbal medicine with rich bio-active ingredients and is used for regulating arrhythmia alongside routine treatments. However, the efficacy and potential mechanisms of Cordyceps on patients with arrhythmia remain unclear. Methods: Randomized controlled trials of bradycardia treatment with Cordyceps were retrieved from diverse databases and available data. Dichotomous variables were expressed as a risk ratio (RR) with a 95% confidence interval (CI). Continuous variables were expressed as a standardized mean difference (SMD) with a 95% CI. Network pharmacology was used to identify potential targets of Cordyceps for arrhythmia. Metascape was used for gene ontology (GO) and genome (KEGG) pathway enrichment analysis. Results: Nineteen trials included 1,805 patients with arrhythmia, of whom 918 were treated with Ningxinbao capsule plus routine drugs, and, as a control, 887 were treated with only routine drugs. Six trials reported on bradycardia and the other 13 on tachycardia. Treatment with Cordyceps significantly improved the total efficacy rate in both bradycardia (RR = 1.24; 95% CI, 1.15 to 1.35; Pz <0.00001) and tachycardia (RR = 1.27; 95% CI, 1.17 to 1.39; Pz <0.00001). Cordyceps also had beneficial secondary outcomes. No serious adverse events occurred in patients treated with Cordyceps. The results of KEGG pathway enrichment analysis were mainly connected to adrenergic signaling in cardiomyocytes and the PI3K-Akt signaling pathway. IL6, TNF, TP53, CASP3, CTNNB1, EGF, and NOS3 might be key targets for Cordyceps in the treatment of arrhythmia. Conclusion: This study confirmed that Cordyceps has a certain positive effect on the treatment of arrhythmia and that its main mechanism may be through the regulation of adrenergic signaling in cardiomyocytes and the PI3K-Akt signaling pathway.
