目的对长沙市1例人感染禽流感h.N6病毒A/Ch.ngsh./1/2022(h.N6)的遗传进化与分子特征进行分析,为防控人感染h.N6禽流感提供依据。方法运用第三代测序平台对样本进行全基因组测序,从美国国家生物技术信息中心(National Center for Biotech.ology Information, NCBI)和全球共享禽流感数据倡议组织(Global Initiative on Sh.ring All Influenza Data, GISAID)数据库下载参考序列进行比对,利用Mega7软件构建遗传进化树并分析关键氨基酸变异位点。结果对序列进行分析发现,本研究毒株属于h.亚型Clade2.***.4.4b分支。PB1与湖南省A/duck/h.nan/S40199/2021(h.N6)同源性为99.69%;PB2与A/Wh.oper swan/Sanmenxia/Y36/2020(h.N8)同源性为98.58%;其余序列与2021年广州发现的毒株A/Guangdong/1/2021(h.N6)高度同源。以上结果表明该病例是由重组的h.N6亚型禽流感病毒感染导致。对毒株序列的氨基酸位点分析发现,裂解位点氨基酸组成为RERRRkR↓GLF,符合高致病性禽流感特征。h.序列中Q226L和G228S位点未发生突变,提示病毒保留结合禽类受体的特征,然而S127P、S137A、T160A、T192R、A267T的突变增加了病毒对人类的亲和性。NA蛋白茎部59-70位点缺失,提示该毒株能增强病毒在哺乳动物体内的毒力。内部基因PB1发生S622G突变,PB2发生k389R和V598T突变,PA发生N409S突变,M1发生N30D和T215A突变,NS1发生P42S突变,这些突变会增强禽流感病毒感染小鼠的毒力。结论本研究的长沙市人感染h.N6病毒为高致病性禽流感病毒,倾向于结合禽类受体,但关键氨基酸位点存在多处变异进而易于感染人类,应持续加强对禽流感h.N6病毒的监测与研究。

背景:虽然目前已有一些研究表明远隔缺血后处理可以发挥神经保护作用,但是具体的机制尚不明了。目的:探讨远隔缺血后处理对大鼠局灶性脑缺血再灌注损伤的保护作用。方法:应用线栓法制备大鼠大脑中动脉闭塞局灶性脑缺血再灌注模型,并进行远隔缺血后处理,同时设假手术组和缺血再灌注组作对照。于缺血再灌注24 h.进行神经功能评分,检测梗死体积及脑含水量;RT-PCR检测缺血周围区脑组织内白细胞介素1β、白细胞介素6、肿瘤坏死因子α和单核细胞趋化蛋白1 mRNA表达情况;Western blot检测Bcl-2和bax蛋白表达情况。结果与结论:与缺血再灌注组相比,远隔缺血后处理组神经功能评分有所降低,但差异无显著性意义,梗死范围和脑组织含水量显著降低(Pbax蛋白表达降低(P<0.05),Bcl-2蛋白表达升高(P<0.05)。结果证实,远隔缺血后处理可以减轻大鼠局灶性脑缺血再灌注产生的损伤,其机制可能与减轻炎性反应有关。
