2Chemical composition and source apportionment of the ambient PM_(2.5)in Hangzhou,China显示文摘To identify and apportion the sources of the ambient PM_(2.5) in the urban area of Hangzhou,China,PM_(2.5)samples were collected at three sites in the city from April 2004 to March 2005.Water-soluble ions,metal elements,and total carbon(TC) in PM_(2.5) samples were analyzed.The results indicated that the 24-h mean concentrations of PM_(2.5) ranged from 17.1 to 267.0 μg/m^3,with an annual average value of 108.2 μg/m^3.Moreover,the seasonal mean values for PM_(2.5) in spring,summer,autumn,and winter were 116,73.1,114.2,and 136.0 μg/m^3.respectively.According to the Chinese ambient quality standard,at least 70% of the monitoring data exceeded the limit value.The total contribution of water-soluble ions,including F^-,Cl^-,NO_3^-,SO_4^(2-).NH_4^+,K^+,and Na^+.to PM_(2.5) mass varied from 32.3% to 36.7%.SO_4^(2-),NO_3^-,and NH_4^+were the main constituents of the ions,with contributions to PM_(2.5) varying from 14.1% to 14.7%,6.0%to 7.8%,and 6.4% to 7.7%,respectively.In addition,the annual mean mass fraction of TC in PM_(2.5) was27.8%.The annual average total contribution of the group of elements of Zn,Pb,Cu,Mn,Cr,Ni,Se,Mo.Cd,Sb,and Ag to the aerosol was in the range of 1.7-2.0%.Furthermore,positive matrix factorization was applied to analyze the PM_(2.5) data collected from the central area,and five factors were identified.The factor contributions to PM_(2.5) mass were 12.8%,31.9%,10.1%,17.2%,and 27.9%,respectively.Iron/steel manufacturing and secondary aerosol were the main sources for the fine particles.These findings may have significance for controlling the atmospheric contamination in the city.Gang Liu Jiuhai Li Dan Wu Hui Xu 2015Particuology2015,13,1:26
3Air pollution characteristics and their relationship with emissions and meteorology in the Yangtze River Delta region during 2014–2016显示文摘With rapid economic growth and urbanization, the Yangtze River Delta(YRD) region in China has experienced serious air pollution challenges. In this study, we analyzed the air pollution characteristics and their relationship with emissions and meteorology in the YRD region during 2014–2016. In recent years, the concentrations of all air pollutants, except O3,decreased. Spatially, the PM2.5, PM10, SO2, and CO concentrations were higher in the northern YRD region, and NO2 and O3 were higher in the central YRD region. Based on the number of non-attainment days(i.e., days with air quality index greater than 100), PM2.5 was the largest contributor to air pollution in the YRD region, followed by O3, PM10, and NO2.However, particulate matter pollution has declined gradually, while O3 pollution worsened.Meteorological conditions mainly influenced day-to-day variations in pollutant concentrations. PM2.5 concentration was inversely related to wind speed, while O3 concentration was positively correlated with temperature and negatively correlated with relative humidity.The air quality improvement in recent years was mainly attributed to emission reductions.During 2014–2016, PM2.5, PM10, SO2, NOx, CO, NH3, and volatile organic compound(VOC)emissions in the YRD region were reduced by 26.3%, 29.2%, 32.4%, 8.1%, 15.9%, 4.5%, and0.3%, respectively. Regional transport also contributed to the air pollution. During regional haze periods, pollutants from North China and East China aggravated the pollution in the YRD region. Our findings suggest that emission reduction and regional joint prevention and control helped to improve the air quality in the YRD region.Tao Ma Fengkui Duan Kebin He Yu Qin Dan Tong Guannan Geng Xuyan Liu Hui Li Shuo Yang Siqi Ye Beiyao Xu Qiang Zhang Yongliang Ma 2019Journal of Environmental Sciences2019,31,9:26

6Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups.YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng 2016Biomedical and Environmental Sciences2016,29,3:18
7Growth-inhibiting effects of taxol on human liver cancer in vitro and in nude mice显示文摘AIM To investigate the effects of taxol onSMMC-7721 human hepatoma and itsmechanisms.METHODS In vitro cell growth was assessedby trypan blue exclusion method.Experimentalhepatoma model was established by seedingSMMC-7721 cells subcutaneously into Balb/c(nu/nu)nude mice.In vivo tumor growth wasdetermined by measurement of tumor diameterwith Vernier calipers.The syntheses of DNA,RNA and protein were analyzed by incorporationof ~3H-thymidine,~3H-uridine and ~3H-leucinerespectively.Using light and electronmicroscopes to observe the morphologicalchanges of cells including mitosis andapoptosis.RESULTS Taxol was effective against SMMC-7721 human hepatoma cell growth in the rangesof 2.5 nmol/L-10 nmol/L with mitotic arrestand apoptosis in vitro.DNA,RNA and proteinsyntheses in cells were also obviouslysuppressed by in vitro treatment of taxol for72 h.Taxol at 2.5 nmol/L reduced ~3H-thymidineuptake to about 34% of the control value(P<0.05).Increasing the dose of taxol to20 nmol/L resulted in a greater decrease in ~3H-thymidine incorporation to 60% of the controlvalue(P<0.01).At a concentration of 20 nmol/L,the ~3H-uridine and ~3H-leucine uptakeswere reduced to 52%(P<0.05)and 63%(P<0.01),respectively.In vivo,taxolsignificantly inhibited SMMC-7721 tumor growthat 10 mg/kg,i.p.,once daily for 10 d.A morethan 90% decrease in tumor volume wasobserved by day 11(P<0.01)similarly withmitotic arrest and cell apoptosis.CONCLUSION Taxol has a marked anticanceractivity in SMMC-7721 human hepatoma both invitro and in nude mice.Its mechanisms might beassociated with mitotic arrest,subsequently,apoptosis of the hepatoma cells.No obvioustoxicity was observed with in vivoadministration of taxoi.Jin Hui Yuan Ru Ping Zhang Ru Gang Zhang Li Xia Guo Xing Wang Wang Dan Luo Yong Xie Hong Xie 2000World Journal of Gastroenterology2000,6,2:18
8Adsorption–desorption behavior of atrazine on agricultural soils in China显示文摘Adsorption and desorption are important processes that affect atrazine transport,transformation,and bioavailability in soils.In this study,the adsorption–desorption characteristics of atrazine in three soils(laterite,paddy soil and alluvial soil) were evaluated using the batch equilibrium method.The results showed that the kinetics of atrazine in soils was completed in two steps:a'fast' adsorption and a 'slow' adsorption and could be well described by pseudo-second-order model.In addition,the adsorption equilibrium isotherms were nonlinear and were well fitted by Freundlich and Langmuir models.It was found that the adsorption data on laterite,and paddy soil were better fitted by the Freundlich model;as for alluvial soil,the Langmuir model described it better.The maximum atrazine sorption capacities ranked as follows:paddy soil > alluvial soil > laterite.Results of thermodynamic calculations indicated that atrazine adsorption on three tested soils was spontaneous and endothermic.The desorption data showed that negative hysteresis occurred.Furthermore,lower solution pH value was conducive to the adsorption of atrazine in soils.The atrazine adsorption in these three tested soils was controlled by physical adsorption,including partition and surface adsorption.At lower equilibrium concentration,the atrazine adsorption process in soils was dominated by surface adsorption;while with the increase of equilibrium concentration,partition was predominant.Lin Yue ChengJun Ge Dan Feng Huamei Yu Hui Deng Bomin Fu 2017Journal of Environmental Sciences2017,29,7:16
9Vascular endothelial growth factor: an attractive target in the treatment of hypoxic/ischemic brain injury显示文摘Cerebral hypoxia or ischemia results in cell death and cerebral edema, as well as other cellular reactions such as angiogenesis and the reestablishment of functional microvasculature to promote recovery from brain injury. Vascular endothelial growth factor is expressed in the central nervous system after hypoxic/ischemic brain injury, and is involved in the process of brain repair via the regulation of angiogenesis, neurogenesis, neurite outgrowth, and cerebral edema, which all require vascular endothelial growth factor signaling. In this review, we focus on the role of the vascular endothelial growth factor signaling pathway in the response to hypoxic/ischemic brain injury, and discuss potential therapeutic interventions.Hui Guo Hui Zhou Jie Lu Yi Qu Dan Yu Yu Tong 2016Neural Regeneration Research2016,11,1:15

12Clinical features of severe pediatric patients with coronavirus disease 2019 in Wuhan: a single center's observational study显示文摘Background An outbreak of coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 was first detected in Wuhan,Hubei,China.People of all ages are susceptible to SARS-CoV-2 infection.No information on severe pediatric patients with COVID-19 has been reported.We aimed to describe the clinical features of severe pediatric patients with COVID-19.Methods We included eight severe or critically ill patients with COVID-19 who were treated at the Intensive Care Unit (ICU),Wuhan Children's Hospital from January 24 to February 24.We collected information including demographic data,symptoms,imaging data,laboratory findings,treatments and clinical outcomes of the patients with severe COVID-19.Results The onset age of the eight patients ranged from 2 months to 15 years;six were boys.The most common symptoms were polypnea (8/8),followed by fever (6/8) and cough (6/8).Chest imaging showed multiple patch-like shadows in seven patients and ground-glass opacity in six.Laboratory findings revealed normal or increased whole blood counts (7/8),increased C-reactive protein,procalcitonin and lactate dehydrogenase (6/8),and abnormal liver function (4/8).Other findings included decreased CD16 + CD56 (4/8) and Th/Ts*(1/8),increased CD3 (2/8),CD4 (4/8) and CD8 (1/8),IL-6 (2/8),IL-10 (5/8) and IFN-γ (2/8).Treatment modalities were focused on symptomatic and respiratory support.Two critically ill patients underwent invasive mechanical ventilation.Up to February 24,2020,three patients remained under treatment in ICU,the other five recovered and were discharged home.Conclusions In this series of severe pediatric patients in Wuhan,polypnea was the most common symptom,followed by fever and cough.Common imaging changes included multiple patch-like shadows and ground-glass opacity;and a cytokine storm was found in these patients,which appeared more serious in critically ill patients.Dan Sun Hui Li Xiao-Xia Lu Han Xiao Jie Ren Fu-Rong Zhang Zhi-Sheng Liu 2020World Journal of Pediatrics2020,16,3:12
13Identification of genomic regions determining flower and pod numbers development in soybean (Glycine max L.)显示文摘Flower and pod numbers per plant are important agronomic traits underlying soybean yield. So far quantitative trait loci (QTL) detected for flower and pod-related traits have mainly focused on the final stage, and might therefore have ignored genetic effects expressed during a specific developmental stage. Here, dynamic expressions of QTL for flower and pod numbers were identified using 152 recom-binant inbred lines (RILs) and a linkage map of 306 markers. Wide genetic variation was found among RILs; 17 unconditional and 18 conditional QTL were detected for the two traits at different developmental stages over two years. Some QTL were detected only at one stage and others across two or more stages, indicating that soybean flower and pod numbers development may be governed by time-dependent gene expression. Three main QTL (qfn-Chr18-2, qfn-Chr20-1, and qfn-Chr19) were detected for flower number, and two main QTL (qpn-Chr11 and qpn-Chr20) were detected for pod number. The phenotypic variation explained by them ranged from 6.1% to 34.7%. The markers linked to these QTL could be used in marker-assisted selection for increasing soybean flower and pod numbers, with the ultimate aim of increasing soybean yield. Comparison of the QTL regions for flower and pod numbers traits with the related genes reported previously showed that seven and four related genes were located in the QTL regions of qfn-Chr11 and qfn-Chr19, respectively. These results provide a basis for fine mapping and cloning of flower and pod development-related genes.Dan Zhang, Hao Cheng, Hui Wang, Hengyou Zhang, Chunying Liu, Deyue Yu National Center for Soybean Improvement, National Key Laboratory of Crop Genetics and Germplasm Enhancement, Nanjing Agricultural University, Nanjing 210095, China 2010Journal of Genetics and Genomics2010,37,8:11

17Detection of a half-microgal coseismic gravity change after the Ms7. 0 Lushan earthquake显示文摘Because only a small near-field coseismic gravity change signal remains after removal of noise from the accuracy of observations and the time and spatial resolution of the earth's surface gravity observation system,it is difficult to verify simulations of dislocation theory.In this study,it is shown that the GS15 gravimeter,located 99.5 km from the epicenter of the Ms7.0 Lushan earthquake on April 20,2013 at 08∶04 UTC+8,showed the influence of the earthquake from 2013-04-16 to 2013-04-26 after a time calibration,tide corrections,drift correction,period correction and relaxation correction were applied to its data.The post-seismic relaxation process of the spring in the gravimeter took approximately 430 minutes and showed a 2.5×10-8ms-2gravity change.After correcting for the relaxation process,it is shown that a coseismic gravity change of approximately+0.59±0.4×10-8ms-2was observed by the GS15 gravimeter;this agrees with the simulated gravity change of approximately 0.31×10-8ms-2.The rate of the coseismic gravity change and the coseismic vertical displacement,as measured by one-second and one-day sampling interval GPS units,is also consistent with the theoretical rate of change.Therefore,the GS15 gravimeter at the Pixian Station observed a coseismic gravity change after the Ms7.0 Lushan earthquake.This and similar measurements could be applied to test and confirm the theory used for these simulations.Wei Jin Zhao Bin Tan Hongbo Yu Dan Shen Chongyang Li Hui 2013Geodesy and Geodynamics2013,4,3:7

20A deep learning-integrated micro-CT image analysis pipeline for quantifying rice lodging resistance-related traits显示文摘Lodging is a common problemin rice,reducing its yield andmechanical harvesting efficiency.Rice architecture is a key aspect of its domestication and a major factor that limits its high productivity.The ideal rice culm structure,includingmajor_axis_culm,minor axis_culm,andwall thickness_culm,is critical for improving lodging resistance.However,the traditionalmethod ofmeasuring rice culms is destructive,time consuming,and labor intensive.In this study,we used a high-throughput micro-CT-RGB imaging system and deep learning(SegNet)todevelopa high-throughputmicro-CTimageanalysis pipelinethatcanextract 24 riceculmmorphological traits and lodging resistance-related traits.When manual and automatic measurements were compared at themature stage,the mean absolute percentage errors for major_axis_culm,minor_axis_culm,andwall_thickness_culmin 104 indica rice accessionswere 6.03%,5.60%,and 9.85%,respectively,and the R^(2) valueswere 0.799,0.818,and 0.623.We also builtmodels of bending stress using culmtraits at the mature and tillering stages,and the R^(2) values were 0.722 and 0.544,respectively.The modeling results indicated that this method can quantify lodging resistance nondestructively,even at an early growth stage.In addition,we also evaluated the relationships of bending stress toshoot dryweight,culm density,and drought-related traits and found that plants with greater resistance to bending stress had slightly higher biomass,culm density,and culm area but poorer drought resistance.In conclusion,we developed a deep learning-integrated micro-CT image analysis pipeline to accurately quantify the phenotypic traits of rice culms in4.6 min per plant;this pipeline will assist in future high-throughput screening of large rice populations for lodging resistance.Di Wu Dan Wu Hui Feng Lingfeng Duan Guoxing Dai Xiao Liu Kang Wang Peng Yang Guoxing Chen Alan P.Gay John H.Doonan Zhiyou Niu Lizhong Xiong Wanneng Yang 2021Plant Communications2021,2,2:7
