Compliance and adherence to oral anticoagulation therapy in elderly patients with atrial fibrillation in the era of direct oral anticoagulants

Thromboembolic complications represent a substantial problem in patients with atrial fibrillation （AF）. The prevalence of AF burden and associated arterial and venous thrombosis progressively increases with age. At the same time, representative national data regarding stroke incidence in AF patients aged 80 and older are limited.

四氢小檗碱药理作用研究进展

四氢小檗碱(THB)属于四氢异喹啉类生物碱,来源于罂粟科植物延胡索的块根,也可由小檗碱氢化合成。与小檗碱比较,THB同样具有多种显著的生物活性。目前研究发现THB具有抗高血压、抗心律失常、抗纤维性颤动、抗急性心肌梗死及对缺血再灌注损伤的治疗及保护作用。也有报道称THB具有抗氧化、调节胃肠功能等作用。通过检索Pubmed、CNKI等数据库,查阅国内外相关文献,旨在对THB的药理作用进行归纳总结,为THB的深入研究提供参考。
