| 1 | Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) emissions from electric arc furnaces for steelmaking显示文摘The proportion of steel produced using electric arc furnaces(EAFs)is increasing.In this study,polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs)concentrations and patterns in stack gas samples from three typical EAFs in steelmaking plants were determined to allow the contributions of EAFs in steelmaking plants to PCDD/Fs emissions in China to be assessed.Samples collection was accomplished by adopting the automatic isokinetic sampling technique,then the PCDD/Fs congeners concentrations were analyzed qualitatively and quantitatively by isotope dilution high-resolution gas chromatography high-resolution mass spectrometry(HRGC-HRMS).The mean PCDD/Fs mass concentrations in stack gases emitted during the scrap preheating phase of plants E1,E2,and E3 were 0.48,385.55,and 0.34 ng Nm^-3,respectively,and the total toxic equivalent(WHO2005-TEQ)concentrations were 0.05,33.16,and 0.03 ng Nm^-3,respectively.The PCDD/Fs mass concentration in stack gases emitted during the melting phase at plant E3 was 0.12 ng Nm^-3(0.02 ng WHO2005-TEQ Nm^-3).The operational temperature of the bag filter of the preheating in the E2 EAF was as high as 230℃,which is conducive to the generation of PCDD/Fs,whether the temperature in the bag filter of E1(150℃)and E3(120℃)are not.Moreover,the bag filter temperature is suggested to be best controlled to below 150℃.The emission factors(EF)for PCDD/Fs released into the air during the scrap preheating phase for plants E1,E2,and E3 were 0.13,52,and 0.10 mg WHO2005-TEQ t1,respectively,and the EF for the smelting phase from plant E3 was 0.14 mg WHO2005-TEQ t1.The emission factor in E2 is 5 times higher than the highest current UNEP toolkit factor for EAFs(10 mg TEQ/tonne steel).Therefore,an update for the UNEP toolkit emission factor for a few case plants is suggested.Several congeners,including 2,3,7,8-TeCDF,1,2,3,4,6,7,8-HpCDF,and 1,2,3,4,6,7,8-HpCDD,were dominant during the preheating phase,while 2,3,7,8-TeCDF,1,2,3,7,8-PeCDF,and 2,3,4,7,8-PeCDF were dominant during the smelting phase.The monitoring data from the case plants helps to better understand the PCDD/Fs emissions of EAFs using preheating process stages.However,a more complete emission inventory requires more case investigations on the PCDD/Fs emissions from representative EAFs steelmaking plants. | Qiuting Yang Lili Yang Jia Shen Yuanping Yang Minxiang Wang Xiaoyun Liu Xuejing Shen Changliang Li Jia Xu Fengfeng Li Da Li Guorui Liu Minghui Zheng | 2020 | Emerging Contaminants2020，6，1： | 3 |
| 2 | Hymecromone:a clinical prescription hyaluronan inhibitor for efficiently blocking COVID-19 progression显示文摘Currently,there is no effective drugs for treating clinically COVID-19 except dexamethasone.We previously revealed that human identical sequences of SARS-CoV-2 promote the COVID-19 progression by upregulating hyaluronic acid(HA).As the inhibitor of HA synthesis,hymecromone is an approved prescription drug used for treating biliary spasm.Here,we aimed to investigate the relation between HA and COVID-19,and evaluate the therapeutic effects of hymecromone on COVID-19.Firstly,HA was closely relevant to clinical parameters,including lymphocytes(n=158;r=−0.50;P<0.0001),C-reactive protein(n=156;r=0.55;P<0.0001),D-dimer(n=154;r=0.38;P<0.0001),and fibrinogen(n=152;r=0.37;P<0.0001),as well as the mass(n=78;r=0.43;P<0.0001)and volume(n=78;r=0.41;P=0.0002)of ground-glass opacity,the mass(n=78;r=0.48;P<0.0001)and volume(n=78;r=0.47;P<0.0001)of consolidation in patient with low level of hyaluronan(HA<48.43 ng/mL).Furthermore,hyaluronan could directly cause mouse pulmonary lesions.Besides,hymecromone remarkably reduced HA via downregulating HAS2/HAS3 expression.Moreover,89%patients with hymecromone treatment had pulmonary lesion absorption while only 42%patients in control group had pulmonary lesion absorption(P<0.0001).In addition,lymphocytes recovered more quickly in hymecromone-treated patients(n=8)than control group(n=5)(P<0.05).These findings suggest that hymecromone is a promising drug for COVID-19 and deserves our further efforts to determine its effect in a larger cohort. | Shuai Yang Yun Ling Fang Zhao Wei Li Zhigang Song Lu Wang Qiuting Li Mengxing Liu Ying Tong Lu Chen Daoping Ru Tongsheng Zhang Kaicheng Zhou Baolong Zhang Peng Xu Zhicong Yang Wenxuan Li Yuanlin Song Jianqing Xu Tongyu Zhu Fei Shan Wenqiang Yu Hongzhou Lu | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 2 |
| 3 | Humanistic caring:the core of nursing显示文摘The voice of calling for humanistic concern is always from uncountable doctor-patient conflicts, from which we often hear a doctor is killed or injured for disputes. Prejudice has been rooted in mind that all doctors and nurses are interest-centered and cold-blooded. To some extent, it's true that patterned questions with a poker face are always more than gentle words with warm smile. Nurses are the ones who keep patients company for the longest time. Therefore, caring matters more for them. The explicit concept of 'caring' will be introduced and we will attach great importance to how nurses can achieve caring. From the following aspects:the practices of loving kindness, the instillation of faith and hope, sensitivity to indicators of disease, improvem ent of healing environment, communication arts etc, you will understand why nurse is the symbol of angel. We can begin with caring about people around us. Our duty is not only to deal the ill but to warm the chill. | CAO Qiuting | 2013 | Journal of Medical Colleges of PLA(China)2013，28，2： | 1 |

| 16 | Dynamic response of concrete face rockfill dam affected by polarity reversal of near-fault earthquake显示文摘In China,an increasing number of high concrete face rockfill dams(CFRDs)are located in high intensity earthquake zones,some of which are close to the seismic fault line.Recordings suggest that near-fault ground motions are characterized by large one-sided velocity pulses.The conventional dynamic analysis of dams,however,neglects the features of strong ground movements.In this study,under different ground motion levels some numerical dynamic studies considering the one-sided broadband pulses of near-fault earthquakes are presented for CFRDs based on a generalized plasticity model for rockfill materials.The results indicate that the displacements of dam crest corresponding to positive and reverse input of near-fault ground motion make a significant difference,while the displacements of the dam crest under artificial seismic waves are similar.Furthermore,using the horizontal and vertical components as simultaneous excitations near the faults,the displacements of the dam crest before and after reversing the motion produce a larger difference than that using a single component.More importantly,the difference of horizontal displacements of the dam crest caused by polarity reversal of near-fault ground motions increases with the increase of earthquake intensity.Due to the randomness and uncertainties of earthquakes,using a stochastic near-field motion input as excitation without considering the polarity(i.e.,positive vs reversed waveform),does not necessarily obtain a conservative result. | Jiang Qiuting Zou Degao Han Huichao Liu Jingmao | 2022 | Earthquake Engineering and Engineering Vibration2022，21，1： | 1 |
