达比加群酯对急性缺血性脑卒中并发心房颤动患者的疗效观察

目的探讨达比加群酯对急性缺血性脑卒中并发心房颤动(AF)患者治疗的有效性及安全性。方法选取本院2018年3月至2020年5月收治的104例急性缺血性脑卒中并发AF患者,按照随机数字表法划分成A、B组,每组52例。2组入院后均给予神经内科常规治疗,在此基础上A应用华法林治疗,B组应用达比加群酯治疗。于治疗前、治疗3个月后测定2组凝血功能指标活化部分凝血活酶时间(APTT)、凝血酶原时间(PT)、D-二聚体(D-D)、采用美国国立卫生研究院卒中量表(NIHSS)评定2组神经功能缺损情况,并统计2组治疗3个月内血栓栓塞及不良反应发生率。结果治疗3个月后,2组APTT、PT与治疗前相比均升高(P<0.05),且APTT、PT水平B组明显较A组高(P<0.05);2组D-D水平及NIHSS评分与治疗前相比均降低(P<0.05),且B组均明显较A组低(P<0.05);2组血栓栓塞发生率比较差异无统计学意义(P>0.05),B组出血事件发生率明显低于A组(P<0.05)。结论对急性缺血性脑卒中并发AF患者应用达比加群酯治疗,可有效延长APTT、PT,降低D-D,且显著减轻神经功能损伤,降低血栓栓塞发生率,且出血风险低,用药安全性高。

The Discovery of the Bivalve Fossil Arguniella from the Lower Cretaceous Shangkuli Formation in Northern Greater Khingan Mountains, China: Implications for Stratigraphic Correlation

Objective Typical Early Cretaceous non-marine bivalve fossils from Eastern Asia are represented by the Arguniella-Sphaerium assemblage,and they were important members of the Jehol Biota.Historically,the genus Arguniella in western Liaoning had been mistakenly identified as the Jurassic Ferganoconcha,re-identified as Arguniella with。
