1良性阵发性位置性眩晕诊断标准显示文摘Bárány学会前庭疾病分类委员会制定了良性阵发性位置性眩晕(BPPV)诊断标准,对BPPV可操作性的诊断标准进行了介绍,包括已明确的BPPV分型和新出现的、有争议的BPPV分型,反映了当前医师对BPPV的临床和病理机制的认识。可以预期,对BPPV的深入理解将进一步促进其分类的不断完善。Michael von Brevern Pierre Bertholon Thomas Brandt Terry Fife Takao Imai Daniele Nuti David Newman-Toker 焉双梅 张欢 杨旭 吴子明 2017中国全科医学2017,20,11:28
2H pylori infection and systemic antibodies to CagA and heat shock protein 60 in patients with coronary heart disease显示文摘AIM: To determine the overall prevalence of H pylori and CagA positive H pylori infection and the prevalence of other bacterial and viral causes of chronic infection in patients with coronary heart disease (CHD), and the potential role of anti-heat-shock protein 60 (Hsp60) anti- body response to these proteins in increasing the risk of CHD development. METHODS: Eighty patients with CHD and 160 controls were employed. We also compared the levels of anti- heat-shock protein 60 (Hsp60) antibodies in the two groups. The H pylori infection and the CagA status were determined serologically, using commercially available enzyme-linked immunosorbent assays (ELISA), and a Western blotting method developed in our laboratory. Systemic antibodies to Hsp60 were determined by a sandwich ELISA, using a polyclonal antibody to Hsp60 to sensitise polystyrene plates and a commercially available human Hsp60 as an antigen. RESULTS: The overall prevalence of H pylori infec- tion was 78.7% (n = 63) in patients and 76.2% (n = 122) in controls (P = 0.07). Patients infected by CagA- positive (CagA+) H pylori strains were 71.4% (n = 45) vs 52.4% of infected controls (P = 0.030, OR = 2.27). Sys-temic levels of IgG to Hsp60 were increased in H pylori- negative patients compared with uninfected controls (P < 0.001) and CagA-positive infected patients compared with CagA-positive infected controls (P = 0.007). CONCLUSION: CagA positive H pylori infection may concur to the development of CHD; high levels of anti- Hsp60 antibodies may constitute a marker and/or a con- comitant pathogenic factor of the disease.Cristina Lenzi Alberto Palazzuoli Nicola Giordano Giuliano Alegente Catia Gonnelli Maria Stella Campagna Annalisa Santucci Michele Sozzi Panagiotis Papakostas Fabio Rollo Ranuccio Nuti Natale Figura 2006World Journal of Gastroenterology2006,12,48:23
3近场脉冲型地震动影响下公路常规梁桥的位移响应分析显示文摘为研究近场速度脉冲型地震动影响下公路常规梁桥的延性需求和震后残余位移,将公路常规梁桥简化为非线性单自由度体系,并采用简单脉冲模型模拟近场速度脉冲型地面运动,通过NSPECTRA软件,系统分析了速度脉冲幅值、脉冲周期以及自振周期、刚度和强度退化、捏拢等对体系延性需求和震后残余位移的影响规律;并采用正交试验设计的极差和方差分析方法,对近场速度脉冲型地震动的特征参数和自振周期间的耦合效应进行了分析。研究结果表明:自振周期和速度脉冲幅值是影响结构延性需求和震后残余位移的主要因素;震后残余位移总体上随速度脉冲幅值的增大而增大;脉冲周期主要影响与最大延性需求对应的自振周期,对震后残余位移的影响较小,且没有规律性;刚度退化和捏拢均会显著增大短周期体系的延性需求,而对长周期体系的影响则可以忽略不计;体系刚度、强度退化或捏拢越严重,其震后残余位移也越大;除自振周期与速度脉冲幅值之间存在一定的耦合效应外,其他参数之间的耦合效应很小。马海滨 卓卫东 谷音 NUTI C FIORENTINO G 2017中国公路学报2017,30,12:6
4带小直径纵筋并外包CFRP的RC圆墩抗震性能研究显示文摘桥梁震害调查显示,钢筋混凝土(RC)桥墩易受损,影响震后救援和灾后重建。采用小直径纵筋替换受损纵筋并外包碳纤维布(CFRP)的技术修复受损桥墩可缩短震后修复周期,节省重建费用。以某不规则连续梁桥的RC圆墩为工程背景,选择小直径纵筋的长度和直径、外包CFRP层数为参数,开展7根缩尺比例为1∶6的RC圆墩试件的拟静力试验;选用OpenSees建立有限元模型,采用试验结果验证其准确性,并开展参数分析。研究结果表明:设置小直径纵筋的桥墩的塑性变形集中在小直径纵筋高度范围内,桥墩破坏被限制在塑性铰区域内;与未设置小直径纵筋的桥墩相比,小直径纵筋使桥墩承载力降低20%~27%,但桥墩位移延性提高42%~85%,曲率延性提高47%~242%,耗能性能提高32%~56%;在满足桥墩承载力设计要求的情况下,使用小直径纵筋可有效提高桥墩抗震性能;设置小直径纵筋的桥墩在小直径纵筋区域内的实测CFRP最大应变明显大于未设置的试件,说明对设置小直径纵筋的桥墩外包CFRP,可防止桥墩过早破坏,提高延性;随着小直径纵筋长度增大或直径减小,桥墩耗能性能先增大后减小;建议以钢筋疲劳寿命需求为下限,塑性铰长度为上限选择小直径纵筋长度;选择满足保证塑性铰以外的纵筋受力始终在弹性范围内的条件下的最大直径为小直径纵筋直径;增大修复区域的混凝土强度可弥补设置小直径纵筋造成的桥墩承载力降低。薛俊青 DAVIDE Lavorato 聂尚杰 陈俊臻 BRISEGHELLA Bruno NUTI Camillo 2022中国公路学报2022,35,2:4
