A randomized controlled trial of indobufen versus aspirin in the prevention of bridging restenosis after coronary artery bypass grafting / 中华心血管病杂志

Objective: To compare the efficacy and safety between indobufen and aspirin in the prevention of restenosis of bridge vessels at 1 year after off-pump coronary artery bypass grafting. Methods: This study was a prospective cohort study. We selected 152 patients who received coronary artery bypass grafting in Beijing Anzhen Hospital from December 2016 to December 2018. Patients were divided into the indobufen group and the aspirin group. Patients in the aspirin group were treated with aspirin and clopidogrel, and patients in the indobufen group were treated with indobufen and clopidogrel. During the 1-year follow-up, the rate of restenosis of saphenous vein bridge and internal mammary artery bridge, the rate of adverse cardiac events and adverse reactions were compared between the two groups. The levels of fibrinogen (FIB), D-dimer (D-D), thrombomodulin (TM) and thrombin-activatable fibrinolysis inhibitor (TAFI) were compared before and after antiplatelet therapy. Results: There were 76 cases in the indobufen group, including 57 males (75.0%), aged (60.3±6.6) years. There were 76 cases in the aspirin group, including 62 males (81.6%), aged (59.7±7.2) years. Baseline data were comparable between the two groups (P>0.05). During the follow-up, 3 cases were lost to follow up. Follow-up was completed in 74 patients in the indobufen group and 75 in the aspirin group. A total of 268 bridging vessels were grafted in the indobufen group and 272 in the aspirin group. One year after surgery, the patency rates of great saphenous vein bridge and internal mammary artery bridge were 94.5% (189/200) and 97.1% (66/68) in the indobuphen group, and 91.3% (189/207) and 96.9% (63/65) in the aspirin group, respectively. There was no significant difference in patency rate of great saphenous vein bridge and internal mammary artery bridge between the two groups (χ²=0.282, 0.345, P>0.05). The total incidence of adverse cardiac events was 5.4% (4/74) in the indobufen group and 6.7% (5/75) in the aspirin group (χ²=0.126, P>0.05). The overall incidence of gastrointestinal adverse reactions was significantly lower in the indobufen group than in the aspirin group (4.1% (3/74) vs. 13.3% (10/75), χ²=4.547, P<0.05). The levels of FIB, D-D, TM and TAFI in the two groups were lower than those before surgery (P<0.05), and there was no statistical significance between the two groups at baseline and post-operation (P>0.05). Conclusion: The efficacy of indobufen combined with clopidogrel in the prevention of 1-year restenosis after coronary artery bypass graft is similar to that of aspirin combined with clopidogrel, but the incidence of adverse reactions is lower, and the safety is higher in patients treated with indobufen combined with clopidogrel compared to aspirin combined with clopidogrel strategy.

Sleep-improving mechanism of Chaiqin Ningshen Granules in insomnia rats: based on hippocampal metabonomics / 中国中药杂志

With the ultra high performance liquid chromatography-quadruple-electrostatic field orbitrap high resolution mass spectrometry(UHPLC-Q Exactive Orbitrap-MS)-based metabonomics technology, this study aims to analyze the effect of Chaiqin Ningshen Granules(CNG) on endogenous metabolites in insomnia rats of liver depression syndrome and explore the sleep-improving mechanism of this prescription. Parachlorophenylalanine(PCPA, ip) and chronic stimulation were combined to induce insomnia of liver depression pattern in rats, and the effect of CNG on the macroscopic signs, hemorheology, and neurotransmitters in the hippocampus of insomnia rats of liver depression syndrome was observed. After the administration, rat hippocampus was collected for liquid chromatography-mass spectrometry(LC-MS) analysis of the metabolomics. Principal component analysis(PCA), partial least squares discriminant analysis(PLS-DA), and orthogonal partial least squares discriminant analysis(OPLS-DA) were employed for analyzing the metabolites in rat hippocampus and screening potential biomarkers. MetPA was used to yield the related metabolic pathways and metabolic networks. The results show that the drugs can significantly improve the mental state, liver depression, and blood stasis of rats, significantly increase the content of 5-hydroxytryptamine(5-HT) and gamma aminobutyric acid(GABA) in hippocampus(except low-dose CNG), and significantly reduce the content of glucose(Glu)(except low-dose CNG). Among them, estazolam and high-dose CNG had better effect than others. Metabolomics analysis yielded 27 potential biomarkers related to insomnia. MetPA analysis showed 4 metabolic pathways of estazolam in intervening insomnia and 3 metabolic pathways of high-dose CNG in intervening insomnia, involving purine metabolism, glycerophospholipid metabolism, histidine metabolism, and caffeine metabolism. CNG can alleviate insomnia by regulating endogenous differential metabolites and further related metabolic pathways. The result lays a basis for further elucidating the mechanism of CNG in improving sleep.

AIM: To investigate the possible signaling pathway that promotes epithelial-mesenchymal transi-tion(EMT)of the lung cancer A549 cells stimulated with muscarinic receptor 3(M3R)agonist carbachol.METHODS:The lung cancer cells A549 were treated with 400 μmol/L carbachol.The morphological changes of the cells were observed under inverted phase contrast microscope.The migration and invasion abilites were measured by Wound healing and Tran-swell assays.qPCR was used to detect the mRNA level of vimentin and E-cadherin.The protein levels of p-AKT,vimentin and E-cadherin were determined by Western blot.RESULTS:After treatment with carbachol,the A549 cells showed loss of the close connection and the cell morphology was transformed from irregular polygon to spindle -like cells.The results of Wound healing and Transwell assays showed that the migration and invasion abilites of the A 549 cells were enhanced.Car-bachol increased the vimentin expression and decreased the E-cadherin expression at mRNA and protein level(P<0.05). The phosphorylation of AKT in the A549 cells was up-regulated(P<0.05).These changes was inhibited by M3R antago-nist 4-DAMP.CONCLUSION:Carbachol promotes EMT in the human lung cancer A 549 cells by activating PI3K/AKT signaling pathway.

Screening and Bioinformatics Analysis of Idiopathic Pulmonary Fibrosis Related Genes / 中山大学学报(医学科学版)

[Objective]We aimed to explore the pathogenic genes of Idiopathic pulmonary fibrosis (IPF) by bioinformatics analy?sis and provide a target for further research.[Methods]Gene data sets GSE53845, GSE24206, GSE10667 were downloaded from the Gene Expression Omnibus database and the differential expression genes of normal tissue and IPF were screened with GEO 2R analysis tool. GO analysis and KEGG pathway enrichment analysis of differentially expressed genes were performed in DAVID database in or?der to find out the biological function and its focused signal pathway in differentially expressed genes during IPF development. In order to study the relationship between differential genes and proteins, STRING and CYTOSCAPE software were used to construct the pro?tein interaction network and MCODE software was used to extract the sub-network modules in the protein-interacting network.[Re?sults]This study found 110 differentially expressed genes, of which 92 were high expression in IPF and 18 were low expression. GO enrichment analysis showed that the up-regulated genes in IPF mainly affected the biological processes such as cell adhesion, bio-ad?hesion and collagen metabolism. The enriched molecular function was mainly involved in the composition of extracellular matrix struc?ture and the binding of calcium ions. The down-regulated proteins are mainly involved in the sensory regulation of the biological pro?cess in IPF. KEGG pathway analysis showed that the up-regulated genes in IPF were mainly involved in receptor interactions, cell ad?hesion and other signaling pathways.[Conclusions]This study uses bioinformatics to screen out the differential genes, some of which have been shown to be involved in IPF, and some genes have not been studied, suggesting that it may be a new research target for IPF pathogenesis.
