RESUMO
Objective::In this study, a network pharmacology-based method was applied to analyze the mechanism of modified Erzhiwan combined with epimedium in treatment of atherosclerosis. Method::The compounds and targets of modified Erzhiwan combined with epimedium were screened in traditional Chinese medicine(TCM) systems pharmacology database and analysis platform (TCMSP) and bioinformatics analysis tool for molecular mechanism of TCM (BATMAN-TCM). Mang related databases were applied to find the target-related to atherosclerosis.The common targets of modified Erzhiwan combined with epimedium and atherosclerosis were got by venn diagrams.Cytoscape 3.6.1 was used to construct ingredients-disease-targets networks.Then protein-protein interaction (PPI) analysis of ingredients-disease-targets was builed in STRING database, and was visualized by Cytoscape 3.6.1, then important modules were analyzed with Moleculaar complex detection(MCODE). Biological information annotation databases (DAVID) was used to carry on gene ontology (GO) analysis and enrichment analysis of gene encyclopedia kyoto encyclopedia of genes and genomes (KEGG) pathway. Result::A total of 38 active ingredients and 266 potential targets of modified Erzhiwan combined with epimedium were obtained from TCMSP and BATMAN-TCM, 254 atherosclerosis-related targets were retrieved from disease database.Then 52 common targets were obtained and 14 core genes were screened.Biological processes were related to inflammatory response, regulation of insulin secretion, positive regulation of nitric oxide biosynthetic process, etc.The biological pathways mainly included tumor necrosis factor signaling pathway, NF-kappa B(NF-κB)signaling pathway, peroxisome proliferators-activated receptors signaling pathway and so on. Conclusion::Modified Erzhiwan combined with epimedium may play the anti-atherosclerosis role by estrogen-like effect through attach estrogen receptor, inhibiting inflammation and improving insulin resistance, which may provide guidance for further experimental research.
RESUMO
<p><b>OBJECTIVE</b>To study the relationship between pathogenesis for Yin-deficiency of acute myocardial infarction (AMI) and immediate prognosis as well as its neuro-endocrine mechanism.</p><p><b>METHODS</b>According to the TCM standard of Syndrome Differentiation of Deficiency Syndrome, 194 patients with AMI were classified into the typical Yin-deficiency group (n = 26), the non-typical Yin-deficiency group (n = 61) and the non-Yin-deficiency group (n = 107). Their venous blood samples were collected in the morning while lying on their backs to detect plasma levels of adrenaline, noradrenaline, aldosterone, atrial natriuretic peptide (ANP), corticoid and myocardial enzymes, as well as their hospitalization days and mortality in hospitalized period were calculated and compared in the three groups, with the 30 healthy persons as control.</p><p><b>RESULTS</b>Levels of serum creatine phosphokinase, creatine phosphokinase isozyme, plasma adrenaline, noradrenaline, aldosterone, hospitalization days and mortality were higher in the Yin-deficiency groups than in the non-Yin-deficiency group (P < 0.05, P < 0.01). As compared the indexes between the typical and the non-typical Yin-deficiency groups, significant difference only showed in plasma aldosterone and ANP, which was significantly higher in the former (P < 0.05, P < 0.01). Plasma corticoid level was insignificantly different between the Yin-deficieny groups.</p><p><b>CONCLUSION</b>Patients with AMI of Yin-deficiency type was severer in myocardial damage, with longer hospitalization period and higher mortality, it is probably due to the hyper-activated sympathetic-adrenaline system and strengthened activity of aldosterone in them.</p>
