| 1 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |
| 2 | Protective effects of taurine against muscle damage induced by diquat in 35 days weaned piglets显示文摘Background: Oxidative stress is a key factor that influences piglets' health. Taurine plays an imperative role in keeping the biological system from damage. This study was conducted to investigate the protective effect of taurine against muscle injury due to the secondary effect of diquat toxicity.Results: Our study found that taurine effectively and dose-dependently alleviated the diquat toxicity induced rise of feed/gain, with a concurrent improvement of carcass lean percentage. The plasma content of taurine was considerably increased in a dose-dependent manner. Consequently, dietary taurine efficiently improved the activity of plasma antioxidant enzymes. Furthermore, taurine attenuated muscle damage by restoring mitochondrial micromorphology, suppressing protein degradation and reducing the percentage of apoptotic cells in the skeletal muscle. Taurine supplementation also suppressed the genes expression levels of the antioxidant-, mitochondrial biogenesis-, and muscle atrophy-related genes in the skeletal muscle of piglets with oxidative stress.Conclusions: These results showed that the dose of 0.60% taurine supplementation in the diet could attenuate skeletal muscle injury induced by diquat toxicity. It is suggested that taurine could be a potential nutritional intervention strategy to improve growth performance. | Chaoyue Wen Fengna Li Qiuping Guo Lingyu Zhang Yehui Duan Wenlong Wang Jianzhong Li Shanping He Wen Chen Yulong Yin | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 5 |

| 9 | Formation of the Looming-evoked Innate Defensive Response during Postnatal Development in Mice显示文摘Environmental threats often trigger innate defensive responses in mammals.However,the gradual development of functional properties of these responses during the postnatal development stage remains unclear.Here,we report that looming stimulation in mice evoked fight behavior commencing at P14-16 and had fully developed by P20-24.The visual-evoked innate defensive response was not significantly altered by sensory deprivation at an early postnatal stage.Furthermore,the percentages of wide-field and horizontal cells in the superior colliculus were notably elevated at P20-24.Our findings define a developmental time window for the formation of the visual innate defense response during the early postnatal period and_provide important insight into the underlying mechanism. | Shanping Chen Huiying Tan Zhijie Wang Yu-ting Tseng Xiaotao Li Liping Wang | 2022 | Neuroscience Bulletin2022，38，7： | 0 |
| 10 | Timing and Single-pulse Study of Pulsar J1909+0122 Discovered by CRAFTS显示文摘We report the discovery of PSR J1909+0122 by the Five-hundred-meter Aperture Spherical Radio Telescope(FAST)as part of the Commensal Radio Astronomy FAST Survey.PSR J1909+0122 has a spin period of 1.257 s and a dispersion measure of 186.2 pc cm^(-3).The averaged pulse profile shows two distinct components.We performed a single-pulse study based on a one-hour observation at 1.25 GHz on 2021 August 23.We used a threshold of 5σ_(ep) to measure the nulling fraction(NF)as 63%±1.5%.The longitude-resolved fluctuation spectra and fast Fourier transform spectra of the binary sequences revealed the quasi-periodicity of nulling with a period of 30 rotation periods.We examined the reliability of the periodicity by comparing it to random noise injection.The NF,E,and modulation periodicity P_(M) of PSR J1909+0122 were compared with other periodic nulling pulsars,showing that the source of J1909+0122 has the second largest NF in the population.Long-term timing observations over six months were used to derive the phase-connected ephemeris of this pulsar.The measured P and P values disfavor dipolar geometry for polar gap models,and the prediction for a space-charge-limited flow model in the case of inverse Compton scattering is only just above the death line.In this work,PSR J1909+0122 has revealed possible correlations between nulling behavior and pulsar properties,which will help to shed light on the pulsar emission mechanism and its temporal evolution in future observations. | Yutong Chen Pei Wang Di Li Erbil Gügercinoğlu Rushuang Zhao Lingqi Meng Jianping Yuan Jiarui Niu Weiwei Zhu Yi Feng Chenchen Miao Chenhui Niu Qingdong Wu Na Wang Shen Wang Xiaoyao Xie Mengyao Xue Jumei Yao Mao Yuan Shanping You Xuhong Yu Youling Yue Jie Zhang Junshuo Zhang Lei Zhang Yabiao Wang Zhenye Gan Yuxi Li Zhongyi Sun Chengjie Wang | 2023 | Research in Astronomy and Astrophysics2023，23，8： | 0 |
| 11 | Metal-Free Synthesis of Benzo[a]phenanthridines from Aromatic Aldehydes,Cyclohexanones,and Aromatic Amines显示文摘A three-component synthesis of benzo[a]phenanthridines from aromatic aldehydes,cyclohexanones,and aromatic amines has been developed,which is mediated by KI/DMSO/camphorsulfonic acid to afford a variety of functionalized benzo[a]phenanthridines in satisfactory yields.The present strategy provides a biaryl motif ortho to the nitrogen atom which has the potential to be used as ligand by further modification.With the advantages of readily available starting materials,transition-metal-free conditions,gram-scale synthesis,and broad substrate scope,this three-component protocol provides an efficient approach for the preparation of diverse benzo[a]phenanthridines. | Pingyu Jiang Zhifei Shan Shanping Chen Quanyuan Wang Shuxin Jiang Haolin Zheng Guo-Jun Deng | 2022 | Chinese Journal of Chemistry2022，40，3： | 0 |
| 12 | Study on Treatment of Heavy Metals in Fly Ash by a Chelating Agent显示文摘The fly ash from two municipal solid waste incineration plants in Shanghai was treated by the self-developed organic composite chelating agent. The results indicated that the stabilization effect of Pb in the fly ash by the composite chelating agent was the best,and the proportions of its easily leaching form in the two kinds of fly ash decreased from 29. 60% and 27. 49% to 3. 05% and 0. 29% respectively. The leaching toxicity of stabilized fly ash was lower than the limits of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste( GB 16889- 2008),so it can be landfilled separately in the landfill site of municipal solid waste. | yu zhaohui zhang ruina bi zhujie chen shanping | 2016 | Meteorological and Environmental Research2016，7，2： | 0 |

| 14 | In situ electron-induced reduction of NOx via CNTs activated by DBD at low temperature显示文摘In this study,a new in situ electron-induced process is presented with carbon nanotubes(CNTs)as a reduction agent activated by dielectric barrier discharge(DBD)for nitrogen oxide(NOx)abatement at low temperature(<407 K).Compared with a single DBD system and a DBD system with activated carbon(DBD-AC),a DBD system with carbon nanotubes(DBD-CNT)showed a significant promotion of NOx removal efficiency and N2 selectivity.Although the 02 content was 10%,the NOv conversion and N2 selectivity in the DBD-CNT system still reached 64.9%and 81.9%at a specific input energy(SIE)of 1424 J^L,and these values decreased to 16.8%,31.9%and 43.2%,62.3%in the single DBD system and the DBD-AC system,respectively.X-ray photoelectron spectroscopy(XPS)and scanning electron microscopy(SEM)were utilized to investigate surface changes in the CNTs after activation by DBD to explore the NO.t reduction abatement mechanism of this new process.Furthermore,the outlet gas components were also observed via Fourier transform infrared spectroscopy(FTIR)to help reveal the NOr reduction mechanism.Experimental results verified that carbon atoms excited by DBD and the structure of CNTs contributed to the synergistic activity of the DBD-CNT system.The new deNOx process was accomplished through in situ heterogenetic reduction reactions between the NOx and carbon atoms activated by the plasma on the CNTs.In addition,further results indicated that the new deNOv process exhibited acceptable S02 tolerance and water resistance. | Weixuan Zhao Liping Lian Xingpeng Jin Renxi Zhang Gang Luo Huiqi Hou Shanping Chen Ruina Zhang | 2020 | Frontiers of Environmental Science & Engineering2020，14，2： | 0 |
| 15 | Effects of Stabilization Heat Treatment on Microstructure and Mechanical Properties of Si‑Bearing 15Cr–9Ni–Nb Austenitic Stainless Steel Weld Metal显示文摘Two 15Cr–9Ni–Nb austenitic stainless steel weld metals with 2.5%Si and 3.5%Si(namely 2.5Si and 3.5Si samples,respectively)were designed and prepared through tungsten inert gas(TIG)welding and then hold at 800℃ or 900℃ for 3 h for stabilization.The microstructure and mechanical properties were investigated both for the as-welded and after-stabilization heat treatment(SHT)weld metals.There are 3.0–4.0%martensite and 2.5–3.5%δferrite in the 2.5Si as-welded weld metal and 6.0–7.0%δferrite in the 3.5Si as-welded weld metal.After SHT,a large amount of martensite formed in the 2.5Si weld metal,andδ→γtransition occurred during the SHT process both for the 2.5Si and 3.5Si weld metals.There were a large amount of coarse NbC and few nanoscale NbC in the as-welded weld metal.During the SHT,a large amount of nanoscale NbC formed in the matrix,while a large number of G phases formed at the austenite grain boundaries and theδ/γinterfaces.The decrease in solid solution C andδferrite content led to the decline of the yield strength of the weld metal after SHT.The martensite formed in 2.5Si weld metal after SHT had less effect on strength because of its low carbon content.The G phases formed during the SHT reduced the impact energy of the weld metal because it promoted the intergranular fracture,while theδ→γtransition reduced the amount of theδ/γinterfaces and avoided the intergranular fracture,which was beneficial for the impact toughness of the weld metals. | Yakui Chen Dong Wu Dianzhong Li Yiyi Li Shanping Lu | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，4： | 0 |
