Molecular Mechanism of Platycodonis Radix- Armeniacae Semen Amarum in Treating Lung Carcinoma Based on Network Pharmacology / 中国实验方剂学杂志

Objective:To screen out the active components of Platycodonis Radix-Armeniacae Semen Amarum, predict the targets and signaling pathways, construct the "multi-components, multi-targets and multi-pathways" interaction network and further investigate their molecular mechanism for the treatment of lung carcinoma based on network pharmacology. Method:Active components and corresponding targets of Platycodonis Radix-Armeniacae Semen Amarum were obtained through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and literature consultation. Therapeutic targeted genes of Platycodonis Radix-Armeniacae Semen Amarum in the treatment of lung carcinoma were obtained from UniProt database and Genecards database. The "components-targets" network was constructed by using Cytoscape 3.6.0 software, and the protein-protein interactions network was constructed by String database and "Generate Style From Statistics" tool in Cytoscape software. Its molecular docking with active components of Platycodonis Radix-Armeniacae Semen Amarum was carried out by using Systems Dock Web Site network server. The Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) enrichment analysis on the therapeutic targets of Platycodonis Radix-Armeniacae Semen Amarum were performed with the Database for Annotation, Visualization Andintegrated Discovery (DAVID). Result:Fourteen active components of Platycodonis Radix-Armeniacae Semen Amarum were screened out, including acacetin, cis-dihydroquercetin, spinasterol, licochalcone B, and luteolin, et al. One hundred and three therapeutic targets were screened out, including nitric oxide synthase 2 (NOS2), prostaglandin endoperoxide synthase 1 (PTGS1), androgen receptor (AR), prostaglandin endoperoxide synthase 2 (PTGS2), and dipeptidyl peptidase 4 (DPP4), et al. Identified signaling pathways mainly involved prostate cancer signaling pathway, small cell lung cancer signaling pathway, hepatitis B signaling pathway and T cell receptor signaling pathway. Conclusion:The possible molecular mechanism of Platycodonis Radix-Armeniacae Semen Amarum for the treatment of lung carcinoma was explored in this study based on network pharmacology, providing the direction for subsequent research.

Correlation Analysis between Serum Complement C3，C4 Levels and LDL-C in Patients with Premature Coronary Artery Disease / 中山大学学报(医学科学版)

@#【Objective】The aim of this study was to investigate the associations between serum complement C3，C4 and low density lipoprotein cholesterol（LDL- C）levels and early- onset coronary heart disease.【Methods】We enrolled 255 cases of coronary angiography confirmed coronary artery disease from January 2018 to September 2018. All the patients were divided into early- onset coronary heart disease group（108 cases）and late- onset coronary heart disease group（147 cases）. Besides ，100 healthy subjects were enrolled and used as controls. Serum levels of C3 ，C4 and LDL-C were analyzed by automatic biochemical analyzer.【Results】Levels of serum C3，C4 and LDL-C in early-onset coronary heart disease group，late-onset coronary heart disease group and healthy control group were significantly different（P < 0.05）. In early-onset coronary heart disease group，C3 and C4 were positively correlated with LDL-C（P < 0.05）. However ，there was no significant correlation （P > 0.05） between C3 ，C4 and LDL- C in late- onset coronary heart disease group and healthy control group.【Conclusions】The levels of C3 and C4 were positively correlated with LDL-C only in the early-onset coronary heart disease patients.
