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
2Plasma and aqueous humor levels of adiponutrin and pannexin 1 in patients with and without diabetic retinopathy显示文摘AIM: To evaluate plasma and aqueous levels of adiponutrin and pannexin 1 in patients with and without diabetic retinopathy.METHODS: The study included three age and gendermatched groups of 20 cataract patients with no diabetes or additional disease(Group C), 20 cataract patients with diabetes and no retinopathy(Group DM+C), and 20 cataract patients with diabetic retinopathy(Group DR+C).All the patients were examined with respect to body mass index(BMI), fasting plasma glucose, hemoglobin A1c(HbA1c), and lipid profile.Phacoemulsification and intraocular lens(Phaco+IOL) implantation were performed to all patients in all the groups, and aqueous samples were taken during the operation.The plasma and aqueous adiponutrin and pannexin 1 levels were analyzed using enzyme-linked immunosorbent assays.RESULTS: A statistically significant difference was determined between the groups with respect to BMI, fasting plasma glucose, and HbA1c levels(P<0.05 for all parameters tested).The plasma adiponutrin levels of Group DR+C were statistically significantly lower than those of Group C and Group DM+C(P<0.001, P=0.004).No statistically significant difference was determined in the aqueous adiponutrin levels in three groups.The plasma pannexin 1 levels of Groups DM+C and DR+C were statistically significantly lower than those of Group C(both P=0.001).The aqueous pannexin 1 levels of Group DR+C were statistically significantly higher than those of Group C and Group DM+C(P=0.001, P<0.001).CONCLUSION: Adiponutrin and pannexin 1, which play an important role in the pathophysiology of diabetes and obesity, and have a regulatory role in hyperglycemia and insulin resistance.The measurement of adiponutrin and pannexin 1 levels may support clinicians in determining the risk of DR development.Fatih Cem Gül Sabiha Güngör Kobat FatihÇelik Süleyman Aydin Ramazan Fazil Akkoç 2022International Journal of Ophthalmology(English edition)2022,15,3:3
