4Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants.Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He 2021National Science Review2021,8,2:47
5Eco-toxicity of petroleum hydrocarbon contaminated soil显示文摘Total petroleum hydrocarbons (TPH) contaminated soil samples were collected from Shengli Oilfield of China. Toxicity analysis was carried out based on earthworm acute toxicity, plant growth experiment and luminescent bacteria test. The soil was contaminated by-petroleum hydrogcarbons with TPH concentration of 10.57%. With lethal and sub-lethal rate as endpoint, earthworm test showed that the LD 50 (lethal dose 50%) values in 4 and 7 days were 1.45% and 1.37% respectively, and the inhibition rate of earthworm body weight increased with higher oil concentration. TPH pollution in the soil inhibited seed germination in both wheat and maize experiment when the concentration of petroleum was higher than 0.1%. The EC 50 (effective concentration 50%) for germination is 3.04% and 2.86% in maize and wheat, respectively. While lower value of EC 50 for root elongation was to be 1.11% and 1.64% in maize and wheat, respectively, suggesting higher sensitivity of root elongation on petroleum contamination in the soil. The EC 50 value in luminescent bacteria test was 0.47% for petroleum in the contaminated soil. From the experiment result, it was concluded that TPH content of 1.5% is considered to be a critical value for plant growth and living of earthworm and 0.5% will affect the activity of luminescent bacteria.Jingchun Tang Min Wang Fei Wang Qing Sun Qixing Zhou 2011Journal of Environmental Sciences2011,23,5:26

8The Chinese Society of Clinical Oncology(CSCO)clinical guidelines for the diagnosis and treatment of nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is a malignant epithelial tumor originating in the nasopharynx and has a high incidence in Southeast Asia and North Africa.To develop these comprehensive guidelines for the diagnosis and management of NPC,the Chinese Society of Clinical Oncology(CSCO)arranged a multi-disciplinary team comprising of experts from all sub-specialties of NPC to write,discuss,and revise the guidelines.Based on the findings of evidencebased medicine in China and abroad,domestic experts have iteratively developed these guidelines to provide proper management of NPC.Overall,the guidelines describe the screening,clinical and pathological diagnosis,staging and risk assessment,therapies,and follow-up of NPC,which aim to improve the management of NPC.Ling-Long Tang Yu-Pei Chen Chuan-Ben Chen Ming-Yuan Chen Nian-Yong Chen Xiao-Zhong Chen Xiao-Jing Du Wen-Feng Fang Mei Feng Jin Gao Fei Han Xia He Chao-Su Hu De-sheng Hu Guang-Yuan Hu Hao Jiang Wei Jiang Feng Jin Jin-Yi Lang Jin-Gao Li Shao-Jun Lin Xu Liu Qiu-Fang Liu Lin Ma Hai-Qiang Mai Ji-Yong Qin Liang-Fang Shen Ying Sun Pei-Guo Wang Ren-Sheng Wang Ruo-Zheng Wang Xiao-Shen Wang Ying Wang Hui Wu Yun-Fei Xia Shao-Wen Xiao Kun-Yu Yang Jun-Lin Yi Xiao-Dong Zhu Jun Ma 2021Cancer Communications2021,41,11:22
9Relation between electricity structure of the crust and deformation of crustal blocks on the northeastern margin of Qinghai-Tibet Plateau显示文摘Study on the electricity structure along a magnetotelluric (MT) sounding profile on the northeastern margin of Qinghai-Tibet Plateau indicates that four crustal blocks can be de-termined from southwest to northeast, namely Bayan Har block (BH), Qin-Qi block (QQ), Hai-yuan block (HY) or the North-South seismotectonic belt and Ordos block (OD). The BH, QQ and OD blocks display a similar electricity structure of the crust. The upper crust represents a high- resistivity layer and the upper part of lower crust represents a low-resistivity layer with the resis-tivity increasing gradually with depth from the lower part of lower crust to the upper mantle. The electricity structure of the crust in these three blocks is similar to that in the complete blocks on the southern and eastern margins of the Qinghai-Tibet Plateau and belongs to normal electricity layering of the crust in slightly deformed or complete intracontinental blocks. The crust in HY block as a boundary zone has been significantly deformed, hence its electricity layering was de-stroyed and the structure was complex and the block became a recent tectonically active and great seismo-active region. The contact belts between the blocks on the northeastern margin of Qinghai-Tibet Plateau exhibit both upthrusting outward and strike-slip movement different from those on the southern and eastern margins of the plateau. The genesis of the low-resistivity layer in the crust is analyzed and the thickness of the lithosphere is estimated in the paper.ZHAO Guoze TANG Ji ZHAN Yan CHEN Xiaobin ZHUO Xianjun WANG Jijun XUAN Fei DENG Qianhui ZHAO Junmeng 2005Science China Earth Sciences2005,48,10:20
10Special 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 2020National Science Review2020,7,9:20
11The sensitivity of digestive tract tumor cells to As_2O_3 is associated with the inherent cellular level of reactive oxygen species显示文摘AIM:To explore the correlation of the inherent cellular ROSlevel with the susceptibility of the digestive tract tumor cellsto apoptosis inducted by As_2O_3.METHODS:Two gastric cercinoma cell lines,SGC7901 andMKN45,and two esophageal carcinoma cell lines,EC/CUHKI(alternatively named EC1.71)and EC1867 with lowconcentration(2μmol·L^(-1))of As_2O_3 were cultured respectly,which confirmed the difference in apoptosis susceptibilitybetween SGC7901 and MKN45,and between EC/CUHK1 andEC1867.The cells were incubated withdihydrogenrhodamine123(DHR123),used as a ROScapture,in absence of As_2O_3.The fluorescent intensity ofrhodamine123,which was the product of cellular oxidationof DHR123,was detected by flow cytometry,and ROS wasmeasured.RESULTS:Apoptosis induced by a low concentration ofAs203 was more readily to occur in SGC7901(22.4%±2.4%)and EC/CUHK1(27.0%±2.9%)than in MKN45(2.1%±0.5%)and EC1867(0.8%±0.5%).In other words,SGC7901was more sensitive than MKN45 to As_2O_3,meanwhile EC/CUHK1 was more sensitive than EC1867 to As_2O_3.The levelof inherent cellular ROS in SGC7901(650±37)was higherthan that in MKN45(507±22)(P<0.01),and the level ofinherent cellular ROS in EC/CUHK1(462±17)was higherthan that in EC1867(187±12)(P<0.01).CONCLUSIONS.The cellular sensitivity to apoptosis inducedby As_2O_3 is associated with the difference in cellular ROSlevel.The inherent ROS level might determinate theapoptotic sensitivity of tumor cells to As_2O_3.Fei Gao Jing Yi Gui-Ying Shi Hui Li Xue-Geng Shi Xue-Ming Tang Department of Cell Biology,Shanghai Second Medical University,Shanghai 200025,China 2002World Journal of Gastroenterology2002,8,1:18

15Top-dressing nitrogen fertilizer rate contributes to decrease culm physical strength by reducing structural carbohydrate content in japonica rice显示文摘Lodging is an important factor limiting rice yield and quality by bending or breaking stem in japonica rice(Oryza sativa L.) production. The objectives of this study were to determine the mechanism of lodging resistance in japonica rice as affected by carbohydrate components, especially its related arrangement in culm tissue and response to top-dressing nitrogen(N) fertilizer. Field experiments were conducted in Danyang County, Jiangsu Province, China, by using two japonica rice varieties Wuyunjing 23(lodging-resistance variety) and W3668(lodging-susceptible variety) with three top-dressing N fertilizer rates(0, 135 and 270 kg N ha^(–1)) in 2013 and 2014. Lodging related physical parameters, morphological characteristics and stem carbohydrate components were investigated at 30 d after full heading stage. Results showed that with increasing N fertilizer rates, the lodging rate and lodging index increased rapidly primarily due to significant reduction of breaking strength in two japonica rice varieties. Correlation analysis revealed that breaking strength was significantly and positively correlated with bending stress, but negatively correlated with section modulus, except for significant correlation at W3668 in 2014. Higher stem plumpness status and structural carbohydrate contents significantly enhanced stem stiffness, despite of lower non-structural carbohydrate. With higher N fertilizer rate, the culm wall thickness was almost identical, and culm diameter increased slightly. The structural carbohydrates, especially for lignin content in culm, reduced significantly under high N rate. Further histochemical staining analysis revealed that high N treatments decreased the lignin deposition rapidly in the sclerenchyma cells of mechanical tissue, large vascular bundle and small vascular bundle region, which were consistent with reduction of bending stress, especially for W3668 and thus, resulted in poor stem strength and higher lodging index. These results suggested that structural carbohydrate plays a vital role for improving stem strength in japonica rice. N rate decreased lodging resistance primarily due to poor stem stiffness, by reducing structural carbohydrate content and lignin deposition in the secondary cell wall of lower internode culm tissue.ZHANG Wu-jun WU Long-mei DING Yan-feng WENG Fei WU Xiao-ran LI Gang-hua LIU Zheng-hui TANG She DING Cheng-qiang WANG Shao-hua 2016Journal of Integrative Agriculture2016,15,5:14
16Selective brain hypothermia-induced neuroprotection against focal cerebral ischemia/reperfusion injury is associated with Fis1 inhibition显示文摘Selective brain hypothermia is considered an effective treatment for neuronal injury after stroke,and avoids the complications of general hypothermia.However,the mechanisms by which selective brain hypothermia affects mitochondrial fission remain unknown.In this study,we investigated the effect of selective brain hypothermia on the expression of fission 1 (Fis1) protein,a key factor in the mitochondrial fission system,during focal cerebral ischemia/reperfusion injury.Sprague-Dawley rats were divided into four groups.In the sham group,the carotid arteries were exposed only.In the other three groups,middle cerebral artery occlusion was performed using the intraluminal filament technique.After 2 hours of occlusion,the filament was slowly removed to allow blood reperfusion in the ischemia/reperfusion group.Saline,at 4℃ and 37℃,were perfused through the carotid artery in the hypothermia and normothermia groups,respectively,followed by restoration of blood flow.Neurological function was assessed with the Zea Longa 5-point scoring method.Cerebral infarct volume was assessed by 2,3,5-triphenyltetrazolium chloride staining,and apoptosis was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining.Fis1 and cytosolic cytochrome c levels were assessed by western blot assay.Fis1 mRNA expression was assessed by quantitative reverse transcription-polymerase chain reaction.Mitochondrial ultrastructure was evaluated by transmission electron microscopy.Compared with the sham group,apoptosis,Fis1 protein and mRNA expression and cytosolic cytochrome c levels in the cortical ischemic penumbra and cerebral infarct volume were increased after reperfusion in the other three groups.These changes caused by cerebral ischemia/reperfusion were inhibited in the hypothermia group compared with the normothermia group.These findings show that selective brain hypothermia inhibits Fis1 expression and reduces apoptosis,thereby ameliorating focal cerebral ischemia/reperfusion injury in rats.Experiments were authorized by the Ethics Committee of Qingdao Municipal Hospital of China (approval No.2019008).Ya-Nan Tang Gao-Feng Zhang Huai-Long Chen Xiao-Peng Sun Wei-Wei Qin Fei Shi Li-Xin Sun Xiao-Na Xu Ming-Shan Wang 2020Neural Regeneration Research2020,15,5:13
17V2O5 Nanospheres with Mixed Vanadium Valences as High Electrochemically Active Aqueous Zinc-Ion Battery Cathode显示文摘AV4+-V2O5 cathode with mixed vanadium valences was prepared via a novel synthetic method using VOOH as the precursor,and its zinc-ion storage performance was evaluated.The products are hollow spheres consisting of nanoflakes.The V4+-V2O5 cathode exhibits a prominent cycling performance,with a specific capacity of 140 mAhg-1 after 1000 cycles at 10 A g.1,and an excellent rate capability.The good electrochemical performance is attributed to the presence of V4+,which leads to higher electrochemical activity,lower polarization,faster ion diffusion,and higher electrical conductivity than V2O5 without V4+.This engineering strategy of valence state manipulation may pave the way for designing high-performance cathodes for elucidating advanced battery chemistry.Fei Liu Zixian Chen Guozhao Fang Ziqing Wang Yangsheng Cai Boya Tang Jiang Zhou Shuquan Liang 2019Nano-Micro Letters2019,11,2:12
18Circadian Rhythm of Calling Behavior in the Emei Music Frog(Babina daunchina) is Associated with Habitat Temperature and Relative Humidity显示文摘Generally, the function of vocalizations made by male anurans are to attract females or defend resources. Typically, males vocalize in choruses during one or more periods in a twenty-four-hour cycle, which varies, however, among species. Nevertheless, the causal factors influencing circadian variations of calling patterns in anuran species are not clear. In this study, male chorus vocalizations were monitored in the Emei music frog(Babina daunchina) for 17 consecutive days during the breeding season, while its habitat air temperature and relative humidity in the course of experiments were measured as well. The results revealed that the circadian calling patterns were characterized by two periods of peak vocalization, which were observed from 0500 h to 0700 h and from 1300 h to 2000 h, while the lowest activity period was found from 2100 h to 2200 h. Both calls/h and notes/h were positively correlated with air temperature and negatively with relative humidity. Overall, our data indicate that the Emei music frogs(B. daunchina) could regulate their vocal activities based on the changes of physical micro-environment(e. g., temperature or humidity) to maximize reproductive success.Jianguo CUI Xiaoyan SONG Guangzhan FANG Fei XU Steven E.

20Low-Dimensional Halide Perovskites and Their Advanced Optoelectronic Applications显示文摘Metal halide perovskites are crystalline materials originally developed out of scientific curiosity. They have shown great potential as active materials in optoelectronic applications. In the last 6 years, their certified photovoltaic efficiencies have reached 22.1%. Compared to bulk halide perovskites, low-dimensional ones exhibited novel physical properties. The photoluminescence quantum yields of perovskite quantum dots are close to 100%. The external quantum efficiencies and current efficiencies of perovskite quantum dot light-emitting diodes have reached 8% and 43 cd A^(-1),respectively, and their nanowire lasers show ultralow-threshold room-temperature lasing with emission tunability and ease of synthesis. Perovskite nanowire photodetectors reached a responsivity of 10 A W^(-1)and a specific normalized detectivity of the order of 10^(12 )Jones. Different from most reported reviews focusing on photovoltaic applications, we summarize the rapid progress in the study of low-dimensional perovskite materials, as well as their promising applications in optoelectronic devices. In particular, we review the wide tunability of fabrication methods and the state-of-the-art research outputs of low-dimensional perovskite optoelectronic devices. Finally, the anticipated challenges and potential for this exciting research are proposed.Jian Zhang Xiaokun Yang Hui Deng Keke Qiao Umar Farooq Muhammad Ishaq Fei Yi Huan Liu Jiang Tang Haisheng Song 2017Nano-Micro Letters2017,9,3:10
