Summary What is already known about this topic?In the 1980s.benzene-induced leukemia(BIL)mainly occurred in shoemaking and painting industries.Now the industry distribution of benzene-induced leukemia may have changed over time.What is added by this report?BlL cases mainly occurred in the manufacturing industry from 2005-2019,especially in private enterprises and small/medium-sized enterprises.The industry with the largest number of new cases of BIL was the general and special equipment manufacturing.The number of leukemia cases in emerging industries such as computer/electronic product manufacturing was found to be increasing.What are the implications for public health practice?Strengthening supervision and regulation of manufacturing,especially of small/medium-sized enterprises and emerging manufacturing industry,may be effective in reducing BIL.

目的观察地塞米松(DX)对创伤性脑损伤(TBI)合并海水淹溺(SWD)大鼠脑水肿的干预效果。方法按照随机数字表法将24只SD大鼠分为假手术组、TBI+SWD组、DX治疗组,每组8只。采用TBI+SWD复合模型,DX治疗组大鼠腹腔注射1 ml的DX(1 mg/kg)。对各组大鼠进行改良神经功能缺损评分(mNSS)和脑组织含水量检测,HE染色观察大鼠海马组织病理改变,免疫组化染色观察大鼠海马组织水通道蛋白4(AQP4)的表达情况。结果与假手术组相比,TBI+SWD组、DX治疗组大鼠的mNSS评分及脑组织含水量明显升高,差异有统计学意义(P0.05)。DX治疗组大鼠较TBI+SWD组伤后各时间点神经元细胞核固缩、细胞肿胀、组织基质疏松均有改善。TBI+SWD组与DX治疗组大鼠伤后各时间点均可见海马组织AQP4阳性表达。结论低剂量DX可以改善TBI+SWD大鼠的脑水肿反应,但脑保护作用可能有限。

International Journal of Digital Earth 2021年第9期14卷 1103-1125页

Geographical simulation is a popular method in geographical and environmental research.Many models developed to address geographic and environmental issues are distributed worldwide.However,due to the lack of portals,these models are still difficult to invoke for geographical simulations in open web environments.This study designs and develops a framework to assemble service-oriented models from volunteers distributed worldwide for geographical simulations on the web.The framework consists of three layers(task layer,data exchange layer,and model execution layer)that establish a network of serviceoriented locally shared models and simulation tasks for user configurations.With the help of such a framework,users can configure simulation tasks and invoke suitable models shared worldwide for geographical simulations.This article provides an application of the distributed simulation of gross primary production(GPP)by the Biome-BioGeochemical Cycles(BGC)model in China.This application shows that the framework can be beneficial for model assembly from volunteers’computers and distributed simulation tasks that are run for geographical and environmental issues,which can be applied to Digital Earth initiatives.

Oxygen-deficient MoO_(x)/Ni_(3)S_(2) heterostructure grown on nickel foam as efficient and durable self-supported electrocatalysts for hydrogen evolution reaction

引用

Frontiers of Chemical Science and Engineering 2023年第4期17卷 437-448页

作者： zihuan Yu Haiqing Yan Chaonan wang Zheng wang Huiqin Yao Rong Liu Cheng Li Shulan Ma Beijing Key Laboratory of Energy Conversion and Storage Materials College of ChemistryBeijing Normal UniversityBeijing 100875China School of Basic Medical Sciences Ningxia Medical UniversityYinchuan 750004China Analytical and Testing Center Beijing Normal UniversityBeijing 100875China Shanghai Institute of Applied Physics Chinese Academy of SciencesShanghai 201800China

High-performance and ultra-durable electrocatalysts are vital for hydrogen evolution reaction(HER)during water splitting.Herein,by one-pot solvothermal method,MoO_(x)/Ni_(3)S_(2) spheres comprising Ni_(3)S_(2) nanoparticles inside and oxygen-deficient amorphous MoO_(x) outside in situ grow on Ni foam(NF),to assembly the heterostructure composites of MoO_(x)/Ni_(3)S_(2)/NF.By adjusting volume ratio of the solvents of ethanol to water,the optimized MoO_(x)/Ni_(3)S_(2)/NF-11 exhibits the best HER performance,requiring an extremely low overpotential of 76 mV to achieve the current density of 10 mA∙cm‒2(η_(10)=76 mV)and an ultra-small Tafel slope of 46 mV∙dec^(-1) in 0.5 mol∙L^(-1) H_(2)SO_(4).More importantly,the catalyst shows prominent high catalytic stability for HER(>100 h).The acid-resistant MoO_(x) wraps the inside Ni_(3)S_(2)/NF to ensure the high stability of the catalyst under acidic conditions.Density functional theory calculations confirm that the existing oxygen vacancy and MoO_(x)/Ni_(3)S_(2) heterostructure are both beneficial to the reduced Gibbs free energy of hydrogen adsorption(|∆G_(H*)|)over Mo sites,which act as main active sites.The heterostructure effectively decreases the formation energy of O vacancy,leading to surface reconstruction of the catalyst,further improving HER performance.The MoO_(x)/Ni_(3)S_(2)/NF is promising to serve as a highly effective and durable electrocatalyst toward HER.

目的了解北京市中小学教师职业紧张现状,探讨其影响因素,为缓解中小学教师职业紧张、保护和促进其身心健康提供依据。方法使用多阶段、PPS抽样法和分层整群随机抽样的方式,选取北京市8个辖区29所学校的中小学教师作为研究对象。结果本次共调查北京市中小学教师2 143人,职业紧张者占16.66%,其中轻度职业紧张者10.27%(220/2 143)、中度职业紧张者3.87%(83/2 143)、重度职业紧张者2.52%(54/2 143)。职业紧张得分为(41.74±8.30)分,其中不同维度得分为社会支持均分(20.14±3.73)分,组织与回报均分(11.81±3.87)分,要求与付出均分(13.45±3.56)分,自主性均分(5.38±1.73)分。多因素logistic回归分析结果显示,不同月均收入和周工作时间的中小学教师职业紧张检出率差异有统计学意义(P均<0.05)。与税后月均收入≥11 000元相比,税后月均收入<9 000元(OR=1.588,95%CI:1.144~2.205)、税后月均收入9 000~<11 000(OR=1.562,95%CI:1.138~2.144)是中小学教师检出职业紧张的危险因素(P均<0.05);与周工作时间≤40 h比较,周工作时间49~<55 h(OR=2.552,95%CI:1.671~3.898)、周工作时间≥55 h(OR=3.502,95%CI:2.341~5.241)是中小学教师检出职业紧张的危险因素(P均<0.05)。结论北京市中小学教师存在不同程度的职业紧张问题且主要是轻度职业紧张,月均收入水平、周工作时间超过48 h是北京市中小学教师职业紧张的主要危险因素。
