Fatal Methemoglobinemia Due to Acute Inhalation of Methyl Nitrite in an Industrial Accident

Methyl nitrite is suggested to cause methemoglobinemia by generating methemoglobin, which may be lethal when the methemoglobin concentration exceeds 70%. However, intoxication with methyl nitrite is seldom reported compared with that with other nitrites. Here, we present an industrial accident involving methyl nitrite inhalation during its synthesis process that resulted in three fatalities and one survivor. The autopsy revealed conspicuous blue-gray discoloration in various parts of the body, including the skin, airway mucosa, vessels, brain, heart, and among other areas. The toxicological tests on the deceased showed methemoglobin concentrations in the blood over the lethal level and increased nitrite ion levels in the blood, gastric contents, liver, and lung tissue compared with those in control samples. The cause of death was determined to be methemoglobinemia-induced hypoxia due to methyl nitrite inhalation. This report provides evidence that in methyl nitrite intoxication, exposure duration has a significant influence on the postmortem changes and likelihood of a fatal outcome may be related to the age of the victim. More attention is required regarding the industrial hazards of this substance.     

Towards global relational theorizing: a dialogue between Sinophone and Anglophone scholarship on relationalism

Abstract

What is ‘relational theorizing’ in International Relations and what can it offer? This article introduces a thematic section that responds to these questions by showing two things. First, relational theorizing is not a doctrine or a method, but a set of analyses that begin with relations rather than the putative essences of constitutively autonomous actors. Second, relational theorizing has emerged from different geo-linguistic traditions, and a relational approach to International Relations (IR) can offer the language and space for increased and productive engagement beyond Anglophone scholarship. This thematic section takes a significant step in this direction by staging a dialogue between Sinophone and Anglophone scholarship on relational IR theorizing. Such an engagement shows points of comparison and contrast, convergence and divergence. In this way, the essays presented here contribute to developing a more ‘global’ IR.

Environmental Stressors and Food Security in China

This article considers the immediate forces influencing China’s food system and food security. By immediate is meant events of the reform period, from the late 1970s to 2008. It begins by asking the question that has preoccupied specialists since the publication of Lester Brown’s Who Will Feed China? in 1995: How much arable land does China have? Is that land area sufficient to insure grain sufficiency? To insure food security? The article focuses on the human pressures on the food production environment, and then treats the effects of socioeconomic change: land, air, and water degradation. The core of the article examines six responses of the state to both perceived and actual environmental stressors: policy restricting arable land conversion, China’s one-child policy, investment in irrigation systems, the South–North Water Diversion Project, large-scale afforestation and reforestation campaigns, and the program to convert marginal agricultural lands to forests and grasslands.     

论先秦人文思潮及其深远影响

中华民族是一个富有人文智慧的民族,早在春秋战国之际的百家争鸣时期,就掀起了中国历史上第一次波澜壮阔的人文思潮。"人文"这个概念,最早见于《周易.贲卦.彖传》,其基本含义,指的是围绕对"人"的关爱所创造出的思想观念。在第一次人文思潮中,先秦诸子的人文创造,对我们民族的文明进步,产生过极其深远的影响。尔后,历代思想家都站在自己所处的时代高度,从不同侧面丰富和发展了先秦诸子的人文理念。今天,回顾总结我国古代的人文传统,发掘其优秀成果,对于借鉴历史、服务现实、培养社会主义新人,都有不可低估的积极意义。     

土地生态价值和经济价值的法律协调

在土地的开发和利用上,由于人类对经济价值的偏好,土地的生态价值长期处于边缘化的状态,这给生态环境造成了硬伤.本文在对土地生态价值边缘化的现状、原因等深入分析的基础上,探索土地经济价值和生态价值的平衡之道,并从法律机制层面对土地生态价值的实现机制路径提出初步构想.     

中国农业银行中间业务竞争力比较分析

本文在研究中国农业银行中间业务发展现状的基础上,通过采用比较分析法,对其结算业务、银行卡业务、担保业务、咨询顾问类业务、其他业务等5个子中间业务与同业分别进行对比,得出了其竞争力较弱的原因:网络银行建设步伐慢,国际化网络不完善;缺乏营销理念,缺少理财产品融合;业务品种较传统,缺乏精细化管理;无投资银行部,无金融控股集团;营销手段落后,综合实力较差等,并提出了一系列相应建议:深化发展网络银行,融合银行卡业务和个人理财业务;逐步完善国际化网络;加快新产品、服务的开发设计;择机成立金融控股公司;落实组织改造,积极发掘人才,培育核心竞争力等.     

“星链”军事化发展及其对全球战略稳定性的影响

美国推进“星链”军事化发展,使得外空安全和全球战略稳定面临严峻挑战,必须对其潜在风险进行提前研判和评估。较之传统外空装备,“星链”具有多维一体的战场网络覆盖能力、延伸全杀伤链的集成性功能以及面向实战化的信息作战优势,将对全球战略稳定格局带来三大冲击：一是冲击首攻稳定性,“星链”既强化了美国先发制人的战略突袭能力,又弥补了军用太空资产固有的脆弱性,提升了美国太空攻防的整体能力;二是冲击危机稳定性,“星链”会加剧外层空间爆发“意外战争”的风险,同时,针对“星链”的制衡与反制措施可能造成外空危机的快速升级,并由战略领域向常规领域扩散;三是冲击军备竞赛稳定性,“星链”具有攻防一体和军民两用属性,可能加剧军备发展的“安全困境”,引发技术扩散和军备竞赛风险。“星链”技术系统的不透明性和不可预测性,导致有关军备控制的信心建立措施难以施行。应对“星链”军事化发展对于全球战略稳定的挑战,必须吸纳涵盖商业部门在内的多元化安全治理主体,构建核、外空、网络和人工智能等多域联动的安全治理机制,推动面向未来的可持续安全治理。     

一切从实际出发

公安工作一切从实际出发,要深入实际调查研究,接触实际,了解实际,研究实际;要善于抓住特点做工作,从省情、市情、县情、乡镇情出发,吃透情况,研究特点,抓好工作;要注意把握形势任务的发展变化,研究透大环境大背景,把形势任务的要求变成实际工作;要切实端正工作指导思想,不唯上不唯书只唯实.     

勇于向失败学习

向失败学习体现为一种冲破传统思维的理念,需有敢于自我否定的勇气,是取得成功后的清醒。公安工作中向失败学习,是寻找公安工作发展的增长点和发展规律,寻找防止和纠正错误的办法。反思公安工作中的失败,定位不准、能效不高、执法不严是当下必须上下共同反思的问题,重要的是要掌握向失败学习的方法,要正确认识和对待失败,找出失败的根源,还要建立向失败学习的机制。
