| 1 | PslG, a self-produced glycosyl hydrolase, triggers biofilm disassembly by disrupting exopolysaccharide matrix显示文摘Biofilms 是在细胞外的矩阵嵌入的微生物的联系表面的社区。Exopolysaccharide 是在维持 biofilm 建筑学并且保护居民 biofilm 细菌免受抗菌剂和主人免疫者攻击的伤害的细胞外的矩阵的一个批评部件。然而,指向矩阵 exopolysaccharides 的自我生产的因素,仍然糟糕被理解。这里,我们显示出那 PslG,在 Pseudomonas aeruginosa 涉及关键 biofilm 矩阵 exopolysaccharide Psl 的合成的蛋白质,阻止 biofilm 形成并且拆卸存在在外长地供应的在 nanomolar 集中的分钟以内的 biofilms。PslG 的水晶结构显示 endoglycosidase 的典型特征。PslG 主要破坏 Psl 矩阵从 biofilms 驱散细菌。PslG 处理显著地提高 biofilm 敏感到抗菌素和巨噬细胞房间,导致在一只老鼠的改进 biofilm 清理植入感染模型。而且, PslG 对大量 Pseudomonas 种类显示出 biofilm 抑制和拆卸活动,显示它在与 biofilm 相关的复杂并发症作斗争的大潜力。 | Shan Yu Tiantian Su Huijun Wu Shiheng Liu Di Wang Tianhu Zhao Zengjun Jin Wenbin Du Mei-Jun Zhu Song Lin Chua Liang Yang Deyu Zhu Lichuan Gu Luyan Z Ma | 2015 | Cell Research2015，25，12： | 13 |
| 2 | 前后多车影响的跟驰模型及稳定性分析显示文摘驾驶员在跟车行驶过程中,通常会通过视野前后车辆的行驶状态来调整自己的跟驰行为,基于此本文提出了一种考虑驾驶员视野内双前车和后车对跟驰车辆影响的改进跟驰模型.根据线性稳定分析方法,得到了改进模型的中性稳定性条件,并通过计算机仿真模拟进行了验证.为了进一步加强验证结果及说明改进模型的优越性,同经典FVD模型进行了数值仿真对比.仿真结果表明:灵敏度α越大越有利于提高改进跟驰系统的稳定性;同经典FVD跟驰模型相比,改进模型抵抗干扰的能力更突出,能够消散交通系统中的微小扰动,具有抑制交通拥堵和稳定交通流的有利作用. | 彭勇 刘世洁 DENNIS Z Yu | 2018 | 交通运输系统工程与信息2018，18，6： | 8 |

| 4 | 中国和日本归因于高钠摄入量的脑卒中死亡率的年龄段队列分析显示文摘该研究旨在评估1990-2016年间中国和日本因高钠摄入量导致的脑卒中死亡率的长期趋势。研究人员从全球疾病负担(global burden of disease,GBD)2016中获得死亡率数据,并采用年龄段队列方法进行分析。年龄标准化死亡率数据显示,与高钠摄入相关的脑卒中死亡率呈下降趋势。中国男性和中国女性每年的净降低率分别为-3.1%和-5.0%;而日本男性和日本女性分别为-4.6%和-5.7%。 | 刘青(译) 叶鹏(审校) Cao J Eshak ES Liu K Gero K Liu Z Yu C | 2019 | 中华高血压杂志2019，27，10： | 6 |
| 5 | 肠系膜下动脉根部淋巴结清扫联合血管低位或高位结扎治疗直肠癌的效果观察显示文摘目的:在结直肠癌手术中,与肠系膜下动脉高位结扎相比,保留左结肠动脉的低位结扎在淋巴结清扫、吻合口漏和肿瘤学结果方面仍存在争议。本研究通过回顾性病例分析探讨腹腔镜直肠癌前切除术中肠系膜下动脉高位结扎或低位结扎对患者近期和远期疗效的影响。方法:回顾性分析2013年至2016年在仁济医院行腹腔镜直肠癌前切除术的614例患者的临床资料,比较低位结扎组和高位结扎组的临床人口学特征、手术时间、IMA根部淋巴结清扫数目、围手术期并发症、术后3年和术后5年的总生存率和无病生存率。两组之间比较采用t检验或χ^(2)检验,生存率采用Kaplan-Meier生存曲线以及Log-rank检验分析。以P<0.05为差异有统计学意义。 | 孙凌宇 俞旻皓 骆洋 LUO Y YU M H HUANG Y Z | 2021 | 结直肠肛门外科2021，27，4： | 6 |

| 7 | 帕劳国预应力连续箱梁长期下挠分析显示文摘帕劳共和国科罗尔岛-巴伦尔图阿普岛桥(简称KB桥)为主跨241 m的预应力混凝土箱梁,通车后KB桥发生长期下挠,严重影响其正常运营,最后垮塌,其教训值得反思。该桥于1977竣工,运营18年后挠度达到1.61 m,1996年对该桥进行了体外预应力加固,却在加固后3个月发生垮塌。挠度分析结果表明:传统的梁理论与三维空间分析相比,误差高达20%,且宽跨比越大,误差越大。三维有限元空间分析采用多种徐变收缩计算模型:美国ACI模型、日本JSCE模型、CEB-FIP模型和GL模型,其挠度计算值要比(18年后)实测值低50%~70%,预测的变形也与实测不符;预应力损失计算值为22%~24%,远低于实测值50%。唯一基于理论的B3模型,采用经验值参数计算得到预应力损失40%,18年后挠度计算值比实测值低42%。如果根据长期实测值调整输入参数,结果可与实际更符合。对于早期挠度及其预测,B3模型能够合理地考虑因截面厚度差异产生的收缩和干燥徐变的速率差异。此外,B3模型还可考虑温度差异和顶板可能发生的开裂。 | 叶华文 王力武 曲浩博 Bazant Z P Yu Q Li G H | 2017 | 中外公路2017，37，5： | 5 |
| 8 | Differing profiles of people diagnosed with acute and chronic hepatitis B virus infection in British Columbia,Canada显示文摘AIM To describe the characteristics of people diagnosed with acute and chronic hepatitis B virus(HBV) infection in British Columbia(BC).METHODS We used data from the BC Hepatitis Testers Cohort(BCHTC),which includes all individuals tested for hepatitis C virus(HCV) or human immunodeficiency virus(HIV) or those diagnosed with HBV or active tuberculosis in BC since 1990.These data were integrated with prescription drug,medical visit,hospitalization and mortality data.HBV cases were classified as acute or chronic according to provincial guidelines.We compared characteristics of individuals by HBV infection group(acute,chronic and negative).Factors associated with acute or chronic HBV infection were assessed with multinomial logistic regression models in comparison to the HBV negative group.RESULTS46498 of the 1058056 eligible BC-HTC participants were diagnosed with HBV infection.4.3% of HBV positive individuals were diagnosed with acute HBV infections while 95.7% had chronic infections.Problematic alcohol use,injection drug use,and HIV or HCV co-infection were more common among individuals diagnosed with acute HBV compared to those with chronic infections and HBV negative individuals.In multivariable multinomial logistic regression models,we observed significant associations between acute or chronic HBV diagnosis and being male,age at HBV diagnosis or birth cohort,South and East Asian ethnicity,HCV or HIV infection,and injection drug use.The odds of acute HBV decreased with increasing age among people who inject drugs,while the opposite was true for chronic HBV.Persons with acute HBV were predominantly White(78%) while those with chronic HBV were mostly East Asian(60%).Relative to Whites,East Asians had 12 times greater odds of being diagnosed with chronic HBV infection.These odds increased with increasing socioeconomic deprivation.CONCLUSION Differences in the profiles of people diagnosed with acute and chronic HBV infection necessitate differentiated screening,prevention,care and treatment programs. | Mawuena Binka Zahid A Butt Stanley Wong Mei Chong Jane A Buxton Nuria Chapinal Amanda Yu Maria Alvarez Maryam Darvishian Jason Wong Gina McGowan Mikhail Torban Mark Gilbert Mark Tyndall Mel Krajden Naveed Z Janjua | 2018 | World Journal of Gastroenterology2018，24，11： | 3 |
