Objective: To explore the value of CYP2C19 genotype polymorphisms for guiding the strategy of anti-platelet therapy in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) with clinical prognosis.
Methods: A total of 326 CAD patients with PCI treatment received CYP2C19 genotype examination. According to CYP2C19 polymorphisms, the patients were divided into 3 groups. The patients with CYP2C19*1/*1, fast metabolism were defined as Routine group, who received clopidogrel 75 mg/day,n=128. The patients with CYP2C19*1/*2, CYP2C19*1/*3, CYP2C19*2/*3, CYP2C19*2/*2, CYP2C19*3/*3, medium and slow metabolism were further divided into 2 groups as High clopidogrel group, who received clopidogrel 150 mg/day,n=99 and Ticagrelor group, who received ticagrelor 90 mg/bid,n=99. The changes of platelet aggregation rate (PAgT) at before and 1, 3, 6 months after PCI were observed, the major adverse cardiac events (MACE) and bleeding condition were compared among different groups at 6 months after PCI.
Results: The PAgT was similar between High clopidogrel group and Routine group at 1, 3, 6 months after PCI, P>0.05;while compared with High clopidogrel group and Routine group, the PAgT decreased in Ticagrelor group at 1, 3, 6 months after PCI,P<0.05. The occurrence of MACE was similar between High clopidogrel group and Routine group at 6 months after PCI,P>0.05; while compared with High clopidogrel group and Routine group, Ticagrelor group had much less MACE occurrence,P<0.05. Ticagrelor group had no more major bleeding events than the other 2 groups,P>0.05.
Conclusion: High dose clopidogrel does not increase MACE occurrence in CAD patients with CYP2C19 medium and slow metabolism after PCI. Ticagrelor may decrease PAgT and MACE occurrence without elevating the major bleeding events.

Objective To study the mechanism of chemotherapy resistance caused by interleukin-6 (IL-6) in ovarian cancer cells and its related signal pathways. Methods Ovarian cancer cell lines A2780(IL-6 receptor positive, while non-IL-6-expressing and cisplatin/paclitaxel-responsive) and SKOV3 cell lines( overexpressing of IL-6 receptor and IL-6 and cisplatin/paclitaxel-resistant) were suitable models for this study. The effect of exogenous (a short period of treatment with recombination IL-6) and endogenous IL-6(by transfecting with plasmid encoding for sense IL-6 ) in A2780 cells or deleting of endogenous IL-6expression in SKOV3 cells (by transfecting with plasmid encoding for antisense IL-6) on the sensitivity to cisplatin and paclitaxel was investigated. Meanwhile, the mechanism of chemotherapy resistance caused by IL-6 in ovarian cancer cells and its related signal pathways were also analyzed. Results We found that both exogenous and endogenous IL-6 induce cisplatin and paclitaxel resistance in non-IL-6-expressing A2780 cells (the resistance multiple to cisplatin and paclitaxel was: exogenous, 6. 25 and 7.31; endogenous, 7. 13 -8. 34 and 7. 61 - 10. 70), while deleting of endogenous IL-6 expression in IL-6-overexpressing SKOV3 cells promotes its sensitivity to anticancer drugs ( the resistance multiple to cisplatin and paclitaxel was 0. 15 and 0. 10, 0. 10 and 0. 08). IL-6 significantly up-regulated the expression levels of mRNA and protein of drug resistance-associated genes, MDR1 and GST-π, and apoptosis-inhibiting genes, bcl-2, bcl-xL and XIAP in a dose-dependent manner in A2780 cells. In accordance with this finding, the mRNA and protein levels of MDR1 and GST-π enhanced in sense IL-6-transfected A2780 cells, and reduced in antisense IL-6-transfected SKOV3 cells compared with the corresponding parental and control vector-transfected cells, which had no difference. It was found that PD98059 [ mitogen-activated protein kinase-extracellular signalregulated kinase (MEK) inhibitor ] and wortmannin [ phosphatidylinositol 3-kinase (PI3K) inhibitor ]significantly antagonized IL-6-induced phosphorylation of extracellular signal-regulated kinase ( ERK ) and protein kinase B (Akt), respectively, and both of them blocked IL-6-induced cisplatin and paclitaxel resistance and the inhibitory effects of PD98059 and wortmannin were dependent on its concentration.Conclusions These data suggest that IL-6-induced chemoresistance may be associated with increase of both drug resistance-associated genes ( MDR1 and GST-π) and apoptosis-inhibiting genes ( bcl-2, bcl-xL and XIAP), and activation of MEK/ERK and PL3K/Akt. Therefore, modulation of IL-6 expression or its related signaling pathway may be a promising strategy of treatment for drug-resistant ovarian cancer.
