| 1 | Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized. | Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang | 2020 | National Science Review2020，7，6： | 6 |
| 2 | Early warning of coal dynamic disaster by precursor of AE and EMR'quiet period'显示文摘Efcient and accurate monitoring and early warning of coal dynamic disaster and other disasters can provide guarantee for the efcient operation of mine transportation system.However,the traditional threshold early warning method often fails to warning some accidents.To address above issues,a new early warning method was proposed based on'quiet period'phenomenon of AE and EMR during fracture.It is found that,a'quiet period'of AE and EMR was present before the load reaches the peak stress,which could be used as one of the precursors to warn the imminent failure of coal and rock specimens.MS and AE signals increased abnormally followed by the phenomenon of'quiet period'before the occurrence of coal dynamic disaster on site,and the decrease of MS events in the'quiet period'is about 57%–88%compared with that in previous abnormal increase stage.During the damage evolution of coal and rock,'quiet period'phenomenon usually occurred at 85%–90%of the peak stress,where the slope of damage parameter curve is almost zero.The'quiet period'of the AE-EMR signals and the low change rate of damage parameter before failure provide a theoretical foundation for the coal dynamic disaster warning based on the'quiet period'precursor found in MS-AE-EMR monitoring system.These fndings will help reduce the number of under-reported events and improve early warning accuracy. | Shengquan He Mengli Qin Liming Qiu Dazhao Song Xiufeng Zhang | 2022 | International Journal of Coal Science & Technology2022，9，3： | 1 |
| 3 | Effects of Two Step Calcination Process on Reaction Sintering Properties of Cordierite Materials显示文摘Cordierite materials were synthesized using natural mineral materials via the two step calcination process.The phase composition and microstructure of the specimens were analysized by X-ray diffraction( XRD) and scanning electron microscopy( SEM),respectively. The sintering properties of cordierite materials were also characterized. The effect of two step calcination process on the reaction sintering properties of cordierite materials was investigated. The results show that the two step calcination process can significantly increase the reaction sintering properties of the cordierite materials. When the weight ratio of the presynthesized cordierite to the premixed raw mineral materials is 2 1,the cordierite materials obtained by the two step calcination process have the higher bulk density and the lower apparent porosity( 2. 18 g·cm-3and 13. 85%,respectively). Furthermore,the addition of presynthesized cordierite clinker in the process of synthesizing cordierite materials can promote the growth of cordierite crystalline size. | QIN Mengli WANG Xitang WANG Zhoufu MA Yan LIU Hao | 2017 | China's Refractories2017，26，3： | 0 |
| 4 | Proteome-wide epitope mapping identifies a resource of antibodies for SARS-CoV-2 detection and neutralization显示文摘Dear Editor,Since December 2019,the coronavirus disease 2019(COVID-19)caused by the severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)has become a worldwide pandemic.1 Significant efforts have been made to generate antibodies to help study COVID-19 pathogenesis,perform diagnostic testing,and develop treatment to neutralize SARS-CoV-2 activity.However,the specific sequence of amino acids recognized and bound by an antibody,the'epitope'is unknown for most antibodies.In this study,we developed a high-throughput epitope mapping platform using a peptide-based SARS-CoV-2 proteome microarray.2 to detect the binding epitopes of 57 commercial antibodies to ORFlab,nudeocapsid(N);spike(S),envelop(E),membrane(M),ORF3a,ORF6,ORF7a,and ORF8 proteins(Supplementary Table S1). | Te Liang Mengli Cheng Fei Teng Hongye Wang Yongqiang Deng Jiahui Zhang Chengfeng Qin Shubin Guo Hui Zhao Xiaobo Yu | 2021 | Signal Transduction and Targeted Therapy2021，6，5： | 0 |
