12019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W 2020中华高血压杂志2020,28,3:516
2东方蜜蜂高效的卫生行为机制对于西方蜜蜂抗病育种的启示显示文摘西方蜜蜂(Apismellifera)在世界各地大范围的蜂群损失现象已引起科学界和公众的广泛关注,其健康状况与东方蜜蜂(Apis cerana)相比明显较劣。东方蜜蜂群内可检测到的病原体和寄生虫相对较少,即它们对于生物威胁具有更强的抵抗力,即便是面对异种入侵的新病原(如蜜蜂残翅病毒)。Lin Z Page P Li L Qin Y Zhang Y Hu F Neumann P Zheng H Dietemann V 蔺哲广 郑火青 胡福良 2016中国蜂业2016,67,12:5
3肝内胆管细胞癌和转移性胰腺导管腺癌的免疫组化鉴别显示文摘在肝脏活检标本中,原发性肝内胆管细胞癌(ICC)和转移性胰腺导管腺癌(PDA)组织学上难以区分,但二者的鉴别具有重要的临床意义。本组实验对41例ICCs和60例PDAs分别进行SLOOP、pVHL、IMP3、肿瘤抑制基因蛋白maspin、MUC5AC及CKl7蛋白的免疫表型评估,以了解这些标志物在两种疾病鉴别诊断中的价值。结果显示:29例(71%)ICCs表达pVHL,PDAs中仅3例(5%)出现pVHL表达。S100P、MUC5AC和CKl7在PDAs中阳性率较高,分别为57例(95%)、40例(67%)和36例(60%),ICCs中S100P、MUC5AC和CK17分别为11例(27%)、5例(12%)及5例(12%)表达。IMP3在ICCs和PDAs中阳性率均为90%。60例(100%)PDA和30例(73%)ICC患者存在maspin的阳性表达。作者对上述标志物表达情况进行归纳后发现,当免疫组化染色结果呈SLOOP-/pVHL+/MUC5AC-/CK17-时提示ICC,呈SLOOP+/pVHL-/MUC5AC+/CK17+和S100P+/pVHL-/MUC5AC-/CK17+时则提示PDA。据此可有效将ICC和PDA鉴别开来。Lok T Chen L Lin F 王慧 余英豪 2014临床与实验病理学杂志2014,30,10:3
4Comparative effectiveness of i-SCAN^(TM) and high-definition white light characterizing small colonic polyps显示文摘AIM:To evaluate accuracy of in vivo diagnosis of adenomatous vs non-adenomatous polyps using i-SCAN digital chromoendoscopy compared with high-definition white light.METHODS:This is a single-center comparative effectiveness pilot study.Polyps(n = 103) from 75 averagerisk adult outpatients undergoing screening or surveillance colonoscopy between December 1,2010 and April 1,2011 were evaluated by two participating endoscopists in an academic outpatient endoscopy center.Polyps were evaluated both with high-definition white light and with i-SCAN to make an in vivo prediction of adenomatous vs non-adenomatous pathology.We determined diagnostic characteristics of i-SCAN and highdefinition white light,including sensitivity,specificity,and accuracy,with regards to identifying adenomatous vs non-adenomatous polyps.Histopathologic diagnosis was the gold standard comparison.RESULTS:One hundred and three small polyps,detected from forty-three patients,were included in the analysis.The average size of the polyps evaluated in the analysis was 3.7 mm(SD 1.3 mm,range 2 mm to 8 mm).Formal histopathology revealed that 54/103(52.4%) were adenomas,26/103(25.2%) were hyperplastic,and 23/103(22.3%) were other diagnoses include 'lymphoid aggregates','non-specific colitis,' and 'no pathologic diagnosis.' Overall,the combined accuracy of endoscopists for predicting adenomas was identical between i-SCAN(71.8%,95%CI:62.1%-80.3%) and high-definition white light(71.8%,95%CI:62.1%-80.3%).However,the accuracy of each endoscopist differed substantially,where endoscopist A demonstrated 63.0% overall accuracy(95%CI:50.9%-74.0%) as compared with endoscopist B demonstrating 93.3% overall accuracy(95%CI:77.9%-99.2%),irrespective of imaging modality.Neither endoscopist demonstrated a significant learning effect with i-SCAN during the study.Though endoscopist A increased accuracy using i-SCAN from 59%(95%CI:42.1%-74.4%) in the first half to 67.6%(95%CI:49.5%-82.6%) in the second half,and endoscopist B decreased accuracy using i-SCAN from 100%(95%CI:80.5%-100.0%) in the first half to 84.6%(95%CI:54.6%-98.1%) in the second half,neither of these differences were statistically significant.CONCLUSION:i-SCAN and high-definition white light had similar efficacy predicting polyp histology.Endoscopist training likely plays a critical role in diagnostic test characteristics and deserves further study.Johanna L Chan Li Lin Michael Feiler Andrew I Wolf Diana M Cardona Ziad F Gellad 2012World Journal of Gastroenterology2012,18,41:3
5欧洲和中国的心脏与肾脏远程缺血预适应研究:一项随机对照试验显示文摘远程缺血预适应(remote ischemic preconditioning,RIPC)对经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后造影剂肾病(contrast-induced nephropathy,CIN)的潜在保护作用尚待确定。该研究为双盲、随机、安慰剂对照的多中心研究,纳入年龄〈85岁,肾清除率为30~60mL/(min·1.73m^2)的有临床适应证的患者,除了直接PCI外均按1∶1给予RIPC或标准治疗。主要终点是CIN的发生率。次要终点是围手术期心肌梗死(peri-procedural myocardial infarction,PMI)的发生率。刘青 叶鹏 Moretti C Cerrato E Cavallero E Lin S Rossi ML Picchi A Sanguineti F Ugo F Palazzuoli A Bertaina M Presbitero P Shao-Liang C Pozzi R Giammaria M Limbruno U Lefèvre T Gasparetto V Garbo R OmedèP Sheiban I Escaned J Biondi-Zoccai G Gaita F Perl L D'Ascenzo F 2018中华高血压杂志2018,26,4:3
6全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A 2016饲料博览2016,0,12:2
