1大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7
2High-pressure granulite from Western Kunlun,northwestern China:Its metamorphic evolution,zircon SHRIMP U-Pb ages and tectonic implication显示文摘High-pressure mafic granulites occurring as lenticular bodies within garnet-amphibolites in Kangxiwar Fault have been first reported in this paper. The P-T conditions of two metamorphic stages were ob-tained using calibrated geothermal barometers and ThermoCalc Program. The peak metamorphic con-dition of these high-pressure granulites is about 760―820℃,1.0―1.2 GPa and the retrograde meta-morphic condition is about 620―720℃,0.7―0.8 GPa. The petrological studies show that they have a near-isobaric cooling P-T path which suggests that the Western Kunlun underwent initial crustal thickening,subsequent exhumation and cooling. The SHRIMP zircon U-Pb dating gives two groups of ages for high-pressure granulites. One is 177±6 Ma which is obtained from the rim of the zircon. We consider this age should be the metamorphic age. And the other is 456±30 Ma which is obtained from the core of the zircon and should be the protolith age. The formation of these high-pressure granulites in western Kunlun is closely correlated with the evolution of the Paleo-Tethys and has important im-plications for the research on Tethys and Paleo-Asian tectonic zone.QU JunFeng ZHANG LiFei AI YongLiang L Zeng WANG JianPing ZHOU Hui WANG ShiYan 2007Science China Earth Sciences2007,50,7:7
3Crustal thickness and composition in the South China Block:Constraints from earthquake receiver function显示文摘Crustal thickness and composition are closely related to geology and tectonic evolution of the region.Studying the differences in the crustal thickness and composition of the South China Block(SCB)is important to gain a comprehensive understanding of multi-phase amalgamation,breakup,reworking,and regional geodynamic processes.In this study,teleseismic data from 135 high-density portable broadband stations from Sino Probe were processed using Common Conversion Point(CCP)stacking and H-κstacking methods.The Moho depth and P-wave and S-wave velocity ratio(V_(p)/V_(s))were studied.Our results revealed several insights about the tectonic processes in the SCB.First,the crustal structure and V_(p)/V_(s)ratios of the Cathaysia Block,Jiangnan Orogenic Belt,and Yangtze Block were significantly different.The average depth of the Moho in the Cathaysia Block was approximately 31 km,and the V_(p)/V_(s)ratios increased from the inland area(1.66)to the coastal area(1.78),indicating the oceanward increase of mafic proportion in the lower crust,which is related to the influence of the Paleo-Pacific Plate westward subduction.Second,the crustal thickness of Jiangnan Orogenic Belt deepens from east ca.31 to the west ca.42 km and the V_(p)/V_(s)ratios varied from 1.75 to 1.64,illustrating a relatively felsic crust,which could have been related to the Mesozoic upper crustal thickening under compression followed by the lower crust removal under the extensional background.Third,the average crustal thickness of the Yangtze Block was 42 km,and the V_(p)/V_(s)ratios ranged from 1.64 to 1.84,presenting a positive correlation between the Moho depth and the V_(p)/V_(s)ratio,which is explained by the relatively thick mafic lower crust.Based on the variations in the crustal structure and V_(p)/V_(s)ratios of the profile,we inferred that the central part of the Jiangnan Orogenic Belt was bounded by the Jiangshan-Shaoxing-Hengyang in the east and the Jiujiang-Shitai-Jishou in the west.The small-scale Moho depth undulations at the intersection of the Cathaysia Block and the Jiangnan Orogenic Belt could be related to the Mesozoic compression-extension geodynamic transformation.Changxin CHEN Qingtian LÜ Ling CHEN Danian SHI Jiayong YAN Yinshuang AI 2022Science China Earth Sciences2022,65,4:3
