目的探讨华法林联合阿托伐他汀对心房颤动(atrial fibrillation,AF)患者脑血栓的预防作用。方法选取90例AF患者,根据华法林抗凝治疗强度分为低强度组(n=45)及标准强度组(n=45),2组均予以阿托伐他汀治疗,低强度组开始予以华法林1.25 mg,国际标准化比值(standard international normalized ratio,INR)达标范围为1.5~2.1;标准强度组开始予以华法林2.5 mg,INR达标范围为2.2~2.7。所有患者均随访1年,比较2组治疗前后的凝血功能指标、临床复合终点事件、安全终点事件、INR及华法林维持剂量。结果治疗后,2组纤维蛋白原(fibrinogen,FIB)、活化部分凝血活酶时间(activated partial thromboplastin time,APTT)和凝血酶原时间(prothrombin time,PT)均高(长)于治疗前(P0.05);2组临床复合终点事件发生率比较,差异无统计学意义(P>0.05);低强度组牙龈出血、皮肤黏膜出血发生率分别为4.44%、8.89%,均低于标准强度组(17.78%、24.44%),P<0.05;低强度组INR及华法林维持剂量均低于标准强度组(P<0.05)。结论不同强度华法林联合阿托伐他汀在AF患者抗凝治疗中的疗效相当,2种方法有相似的临床复合终点事件发生率,但低强度华法林联合阿托伐他汀治疗有利于预防出血。

In 2013, the 29th Chinese National Antarctic Research Expedition（CHINARE） prospected the Prydz Bay on the Antarctic continental shelf, and the Chinese R/V Xuelong icebreaker sampled all of the examined locations. The nature of Antarctic fish diversity in the high-latitude Prydz Bay is virtually unknown, and the accuracy of relevant estimates has not been established. Thus, it is necessary to evaluate this diversity and propose protective measures. In total, ninety-nine specimens were collected from various locations. To overcome uncertainties associated with identifying species based on morphology, DNA barcoding（COI gene） was employed to reconstruct phylogenetic relationships with delimited references from NCBI. Twenty-two species representing six families were unambiguously identified from a neighbor-joining（NJ） tree and barcoding gaps. With the morphological identification, thirteen species were identified correctly, five species were identified correctly at the genus level, and four species were identified at the close sister species level. Notothenioid dominance was not evident in the Prydz Bay, in contrast to other published studies. The low species diversity and catch biomass during this CHINARE were severely constrained by limited fishing methods and localized sites, which led to biased underestimation. Our analyses indicate that DNA barcoding is an effective tool for the identification of fish species in the Prydz Bay. The identification and distribution of Antarctic fish should be an integral component of understanding Antarctic fish biodiversity and biogeography, and large-scale studies are necessary for the further taxonomic identification of Antarctic fish.
