RESUMEN

Objective: To explore the impact of ticagrelor on platelet aggregation in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention(PCI). Methods: A total of 98 ACS patients received PCI in our hospital from 2015-01 to 2015-12 were enrolled. The patients were randomly divided into 2 groups: Clopidogrel group, the patients received oral clopidogrel 300mg at first time and then maintained by 75mg/qd, n=48 and Ticagrelor group, the patients received oral ticagrelor 180mg at first time and then maintained by 90mg/bid, n=50. All patients were treated for 12 months.The level of vasodilator stimulated phosphoprotein (VASP) phosphorylation and platelet reactivity index (PRI) at pre-medication and 24h, 7 days and 1 month after PCI were detected; major adverse cardiovascular events (MACE) and bleeding events were recorded within 1 month after PCI, the incidence of platelet aggregation, MACE and bleeding events were compared between 2 groups.Results: The baseline information and PCI condition were similar between 2 groups, P>0.05. The overall average PRI was different between 2 groups, P0.05. Conclusion: Ticagrelor was superior toclopidogrel for anti-platelet aggregation in ACS patients after PCI, it didn't increase bleeding events.

RESUMEN

Objective Discuss the treatment mechanism of Xiaofeng Xuanqiao Decoction on guinea pig with al ergic rhinitis. [Methods]Sixty guinea pigs were randomized into 6 groups: normal control group, al ergic rhinitis(AR) group, high-dosage, equivalent-dosage, low-dosage Xiaofeng Xuanqiao decoction group, and loratadine group. AR guinea pig model was successful y established by ovalbumin(OVA) chal enge method. Xiaofeng Xuanqiao decoction and loratadine were applied to intervene AR guinea pig. The serum levels of IgE and IL-4, IFN-γ, histamine were determined by ELISA methods. [Results]The expression levels of IgE and IL-4, histamine significantly increased,meanwhile the level of IFN-γsignificantly lower compared with the normal group(P<0.01). Compared with that in AR model group, the serum level of IgE and IL-4, histamine in high-dosage Xiaofeng Xuanqiao decoction group significantly decreased,but the level of IFN-γ increased(P<0.01); the levels of IgE and IL-4, histamine decreased in other medication groups, meanwhile the level of IFN-γ increased compared with the model group(P<0.05).[Conclusion]Xiaofeng Xuanqiao can promote the produce of IFN-γ, inhibit the formation of IL-4, promote the secretion of Th1/Th2 cytokines to restore balance, to relieve eosinophil activation, reduce the synthet-ic of IgE, reduce the release of histamine, in many ways to prevent al ergic rhinitis inflammation, to achieve therapeutic effect.
