大家还是要尊重一下基本的事实吧!请看“新英格兰医学杂志”上发表的关于美国第一例新冠病毒患者的报告。

(2020-03-21 17:17:35) 下一个

感谢concode网友,今天贴出了一个链接(https://bbs.wenxuecity.com/currentevent/2061909.html),是本月初发表在“新英格兰医学杂志”(The New England Journal of Medicine)上关于美国第一例新冠病毒患者的报告的中译版。我这里将中译版和英文原文的链接同时贴在下面,给有兴趣的网友做参考。

这里只摘录两段:

一、病例报告中的一段

On January 19, 2020, a 35-year-old man presented to an urgent care clinic in Snohomish County, Washington, with a 4-day history of cough and subjective fever. On checking into the clinic, the patient put on a mask in the waiting room. After waiting approximately 20 minutes, he was taken into an examination room and underwent evaluation by a provider. He disclosed that he had returned to Washington State on January 15 after traveling to visit family in Wuhan, China. The patient stated that he had seen a health alert from the U.S. Centers for Disease Control and Prevention (CDC) about the novel coronavirus outbreak in China and, because of his symptoms and recent travel, decided to see a health care provider.

【2020年1月19日,一名35岁男性因咳嗽和自觉发热4日到华盛顿州斯诺霍米什县的急诊诊所就 诊。患者一进诊所就在候诊室里戴上了口罩。等待大约20分钟后,他被带进了检查室,并接受了医师评估。患者透露他之前曾在中国武汉探亲,并于1月15日返回华盛顿州。患者说他看到了美国疾病控制和预防中心(CDC)关于中国新型冠状病毒暴发的健康警报,考虑到自己的症状和近期旅行史,决定来就诊。】

二、基因测序

Genetic Sequencing On January 7, 2020, Chinese researchers shared the full genetic sequence of 2019-nCoV through the National Institutes of Health GenBank database16 and the Global Initiative on Sharing All Influenza Data (GISAID)17 database; a report about the isolation of 2019-nCoV was later published.18 Nucleic acid was extracted from rRT-PCR–positive specimens (oropharyngeal and nasopharyngeal) and used for whole-genome sequencing on both Sanger and next-generation sequencing platforms (Illumina and MinIon). Sequence assembly was completed with the use of Sequencher software, version 5.4.6 (Sanger); minimap software, version 2.17 (MinIon); and freebayes software, version 1.3.1 (MiSeq). Complete genomes were compared with the available 2019-nCoV
reference sequence (GenBank accession number NC_045512.2).

【2020年1月7日,中国研究人员在美国国立卫生研究院GenBank数据库 (http://#16)和“全球流感数据共享计划”(Global Initiative on Sharing All Influenza Data,GISAID) (http://#17)数据库共享了2019-nCoV的完整基因序列;之后又发表了关于分离2019-nCoV的报告 (http://#18)。核酸是从rRT-PCR阳性样本(口咽部和鼻咽部)提取出,并在桑格和二代测序平台(Illumina和MinIon)进行了全基因组测序。序列组装采用的是5.4.6版Sequencer软件(Sanger)、2.17版minimap软件(MiniON)和1.3.1版freebayes软件(MiSeq)。我们将完整基因组与已发布的2019-nCoV参考序列
(GenBank登录号NC_045512.2)进行了比较。】

Results: The full genome sequences from oropharyngeal and nasopharyngeal specimens were identical to one another and were nearly identical to other available 2019-nCoV sequences. There were only 3 nucleotides and 1 amino acid that differed at open reading frame 8 between this patient's virus and the 2019-nCoV reference sequence (NC_045512.2). The sequence is available through GenBank (accession number MN985325).

【结果:口咽和鼻咽样本的全基因组序列完全相同,并且与已发布的其他2019-nCoV序列几乎相同。在该患者的病毒和2019-nCoV参考序列(NC_045512.2)之间,只有位于开放阅读框8的3个核苷酸和1个氨基酸存在差异。该序列参见GenBank(登录号MN985325) (http://#16)。】
