1Air pollutants contribution and control strategies of energy-use related sources in Beijing显示文摘Based on the statistical analysis of emission inventory and ISCST3 model simulation, the emission and ambient concentration contributions of energy-use related sources to the major pollutants of SO2, NOx and PM10 in urban areas of Beijing were analyzed. The SO2 emission contributions of coal burning in power plants, industrial and heating sectors were 49%, 26% and 24% respectively. The vehicle exhaust contributed 74% of the NOx concentration. As to PM10, the industrial sector was the largest emission (28%) and concentration (21%) contributor despite of the fugitive sources. The source emission contributions of VOC and NH3, which greatly influence the generation of secondary pollutants, were discussed as well. This paper also analyzed the control strategies of energy consumption and vehicle sources, based on which the control scenario in 2008 was established and the change of emission and concentration contribution were estimated. The results show that the cleaner energy use, industrial structure improvement, transportation mode modification and single vehicle emission control will greatly improve air quality. The industrial sector will change to the largest contributor of SO2 and as to NOx, vehicle emission control is still important.HAO Jiming WANG Litao LI Lin HU Jingnan YU Xuechun 2005Science China Earth Sciences2005,48,z2:24
2Effect of human umbilical cord-derived mesenchymal stem cells on lung damage in severe COVID-19 patients:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Treatment of severe Coronavirus Disease 2019(COVID-19)is challenging.We performed a phase 2 trial to assess the efficacy andsafety of human umbilical cord-mesenchymal stem cells(UC-MScs)to treat severe coViD-19 patients with lung damage,based onour phase 1 data.In this randomized,double-blind,and placebo-controlled trial,we recruited 101 severe coVID-19 patients withlung damage.They were randomly assigned at a 2:1 ratio to receive either UC-MSCs(4×10^(7)cells per infusion)or placebo on day 0,3,and 6.The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28.Other imagingoutcomes,6-minute walk test(6-MWT),maximum vital capacity,diffusing capacity,and adverse events were recorded and analyzed.In all,100 COVID-19 patients were finally received either UC-MSCs in=65)or placebo(n=35).UC-MSCs administrationexerted numerical improvement in whole lung lesion volume from baseline to day 28 compared with the placebo(the mediandifference was-13.31%,95%Cl-29.14%,2.13%,P=0.08).UC-MSCs significanty reduced the proportions of solid componentlesion volume compared with the placebo(median difference:-15.45%;95%CI-30.82%,-0.39%;P=0.043).The 6-MWT showedan increased distance in patients treated with UC-MSCs(difference:27.00 m;95%CI 0.00,57.00;P=0.057).The incidence of adverseevents was similar in the two groups.These results suggest that UC-MSCs treatment is a safe and potentially effective therapeuticapproach for COVID-19 patients with lung damage.A phase 3 trial is required to evaluate effects on reducing mortality andpreventing long-term pulmonary disability.Lei Shi Hai Huang Xuechun Lu Xiaoyan Yan Xiaojing Jiang Ruonan Xu Siyu Wang Chao Zhang Xin Yuan Zhe Xu Lei Huang Jun-Liang Fu Yuanyuan Li Yu Zhang Wei-Qi Yao Tianyi Liu Jinwen Song Liangliang Sun Fan Yang Xin Zhang Bo Zhang Ming Shi Fanping Meng Yanning Song Yongpei Yu Jiqiu Wen Qi Li Qing Mao Markus Maeurer Alimuddin Zumla Chen Yao Wei-Fen Xie Fu-Sheng Wang 2021Signal Transduction and Targeted Therapy2021,6,3:13

4Changes in the spatial scale of Beijing UHI and urban development显示文摘The seasonal and interannual variations of Beijing urban heat island (UHI) are investigated in this paper using the temperature data from 1960 to 2000 at 20 meteorological stations in the Beijing region, and then the relationship between the intensity and spatial scale of UHI and Beijing urbanization indices is analyzed and discussed. Main conclusions are the followings. First, Beijing UHI shows obvious seasonal variations, and it is strongest in winter, next in spring and autumn, and least in summer. The seasonal variation of the UHI mainly occurs in the urban area. The UHI intensity at the center of Beijing is more than 0.8℃ in winter, and only 0.5℃ in summer. Second, the intensity of Beijing HUI exhibits a clear interannual warming trend with its mean growth rate (MGR) being 0.3088℃/10 a. The MGR of HUI is largest in winter, next in spring and autumn, and least in summer, and the urban temperature increase makes a major contribution to the growth of HUI intensity. Third, since the Reform and Opening, the urbanization indices have grown several ten times or even one hundred times, the intensity of HUI has increased dramatically, and its spatial scale also expanded distinctively along with the expansion of urban architectural complexes. Fourth, the interannual variation of urbanization indices is very similar with that of HUI intensity, and their linear correlation coefficients are significant at a more than 0.001 confidence level.YU Shuqiu, BIAN Lingen & LIN Xuechun State Key Laboratory on Severe Weather, Chinese Academy of Meteorological Sciences, Beijing 100081, China National Climate Center, China Meteorological Administration, Beijing 100081, China 2005Science China Earth Sciences2005,48,z2:5
5152 W high-power blue diode laser operated at 447 nm显示文摘We demonstrate a high-power blue diode laser operated at 447 nm combining laser diodes using an optical fiber bundle. As many as 127 diode lasers at 447 nm were coupled into 400 μm/0.22 NA fibers using an aspherical lens group with different focus lengths. The bare fibers were mechanically bundled through high temperature ultraviolet adhesive after the coatings of the 127 fibers were stripped. The diameter of the fiber bundle was 6 mm. The total output power of such a bundle was 152 W with electro-optical conversion efficiency of 27.56%and the RMS power instability was less than ±1% within 3 h.Peng Wu Ling Zhang Haijuan Yu Xiandan Yuan Zhiyan Zhang Pengfei Zhao Shuzhen Zou Chaojian He Yaoyao Qi Yingying Yang Gang Li Xubao Wang Xuechun Lin 2017Journal of Semiconductors2017,38,7:4
6The next detectors for gravitational wave astronomy显示文摘This paper focuses on the next detectors for gravitational wave astronomy which will be required after the current ground based detectors have completed their initial observations, and probably achieved the first direct detection of gravitational waves. The next detectors will need to have greater sensitivity, while also enabling the world array of detectors to have improved angular resolution to allow localisation of signal sources. Sect. 1 of this paper begins by reviewing proposals for the next ground based detectors,and presents an analysis of the sensitivity of an 8 km armlength detector, which is proposed as a safe and cost-effective means to attain a 4-fold improvement in sensitivity. The scientific benefits of creating a pair of such detectors in China and Australia is emphasised. Sect. 2 of this paper discusses the high performance suspension systems for test masses that will be an essential component for future detectors, while sect. 3 discusses solutions to the problem of Newtonian noise which arise from fluctuations in gravity gradient forces acting on test masses. Such gravitational perturbations cannot be shielded, and set limits to low frequency sensitivity unless measured and suppressed. Sects. 4 and 5 address critical operational technologies that will be ongoing issues in future detectors. Sect. 4 addresses the design of thermal compensation systems needed in all high optical power interferometers operating at room temperature. Parametric instability control is addressed in sect. 5. Only recently proven to occur in Advanced LIGO, parametric instability phenomenon brings both risks and opportunities for future detectors. The path to future enhancements of detectors will come from quantum measurement technologies. Sect. 6 focuses on the use of optomechanical devices for obtaining enhanced sensitivity, while sect. 7 reviews a range of quantum measurement options.BLAIR David JU Li ZHAO ChunNong WEN LinQing MIAO HaiXing CAI RongGen GAO JiangRui LIN XueChun LIU Dong WU Ling-An ZHU ZongHong HAMMOND Giles PAIK Ho Jung FAFONE Viviana ROCCHI Alessio BLAIR Carl MA YiQiu QIN JiaYi PAGE Michael 2015Science China(Physics,Mechanics & Astronomy)2015,58,12:3
7Progress of the injection laser system of SG-Ⅱ显示文摘A high power laser system was used to drive the ignition of inertial confinement fusion(ICF), of which the high energy,the uniform focal spot, the accurate laser waveform, and the synchronization between the laser beams are key parameters.To accomplish this, global laser characteristics control should be assured, which was the main purpose of the injection laser system. In this paper, the key technological progress involved in the improvement of the performance of the injection laser of SG-II is reported, including frequency domain control, time domain control, near-field spatial shaping, preamplifier technology, and the optical parametric chirped pulse amplification pump source.Wei Fan Youen Jiang Jiangfeng Wang Xiaochao Wang Dajie Huang Xinghua Lu Hui Wei Guoyang Li Xue Pan Zhi Qiao Chao Wang He Cheng Peng Zhang Wenfa Huang Zhuli Xiao Shengjia Zhang Xuechun Li Jianqiang Zhu Zunqi Lin 2018High Power Laser Science and Engineering2018,6,2:3
8Effect of Ningmitai capsule plus sertraline on patients with premature ejaculation and enlarged seminal vesicles:A randomized clinical trial显示文摘OBJECTIVE: To investigate the effects of Ningmitai capsule combined with sertraline on patients with premature ejaculation(PE) and an increased anterior-posterior diameter(APD) of the seminal vesicles(SVs).METHODS: Sixty men with acquired PE were enrolled and randomly divided into two groups. The combined group was treated with Ningmitai capsule and sertraline, while the control group was treated with sertraline alone. Main outcomes were measured using the premature ejaculation diagnostic tool(PEDT), APD of SVs, and Clinical Global Impression of Change questionnaire and compared before and after 3 months of treatment.RESULTS: Comparing after treatment with before treatment outcomes within each group, the PEDT score was significantly reduced in the combined group(12.1 ± 2.5 vs 8.6 ± 3.2, P < 0.001, respectively) and control group(12.9 ± 2.6 vs 10.3 ± 1.6, P <0.001, respectively). Furthermore, the PEDT score after treatment was significantly lower in the combined compared with control group(8.6 ± 3.2 vs10.3 ± 1.6, P = 0.011, respectively). The APD of SVs in the combined group was significantly decreased after treatment [(10.8 ± 2.4) vs(12.9 ± 2.2) mm, P =0.001], while the APD of SVs in the control group was equivalent before and after treatment. The treatment response rate was not significantly higher in the combined compared with control group.CONCLUSION: These results indicated that the effect of Ningmitai capsule combined with sertraline was better than that of sertraline alone for the treatment of PE patients exhibiting an increased APD of SVs. The therapeutic effect found for the combined treatment may be due to antibacterial and anti-inflammatory activity reported for Ningmitai capsule,and may suggest that seminal vesiculitis is a potential pathophysiological factor in acquired PE.Peng Longping Hong Zhiwei Shen Jiaming Hu Xuechun Shao Yong Jing Jun Lu Jinchun Yao Bing 2018Journal of Traditional Chinese Medicine2018,38,2:3
9A New Ductile Fracture Criterion and Its Application to the Prediction of Forming Limit in Deep Drawing显示文摘With considering the influence of equivalent plastic strain on void-damage and taking Lemaitre damage equivalent stress as plastic potential, based on continuous damage mechanics theory, a new criterion for ductile fracture is derived. The two key material constants in the criterion are determined by the combination of tension tests with FE (finite element) simulation. On the basis of the values of stress and strain calculated from commercial finite element software, the forming limit in cylindrical deep drawing of annealed aluminum alloy LY12(M) is predicted by means of the new ductile fracture criterion. Experiments verify that the predicted results are in agreement with the experimental ones. Hence, it is reliable to predict the forming limit in deep drawing by means of the new ductile fracture criterion.Yuying YANG Zhongqi YU Xuechun LI Zhenzhong SUN 2003Journal of Materials Science & Technology2003,19,z1:3
10p53 deficiency-induced Smad1 upregulation suppresses tumorigenesis and causes chemoresistance in colorectal cancers显示文摘The DNA damage response helps to maintain genome integrity,suppress tumorigenesis,and mediate the effects of radiotherapy and chemotherapy.Our previous studies have shown that Smad1 is upregulated and activated by Atm in DNA damage response,which can further bind to p53 and promote p53 stabilization.Herewe report another aspect of the interplay between p53 and Smad1.Comparison of rectal tumor against paired paraneoplastic specimens and analysis of>500 colorectal tumors revealed that Smad1 was upregulated in tumor samples,which was attributable to p53 defects.Using MEFs as a model,we found that knockdown of the elevated Smad1 in p532/2 MEFs promoted cell proliferation,E1A/Ras-induced cell transformation,and tumorigenesis.Mechanistic studies suggest that elevated Smad1 and momentary activation inhibit cell proliferation by upregulating p57Kip2 and enhancing Atm–Chk2 activation.Surprisingly,elevated Smad1 appears to have a negative effect on chemotherapy,as colorectal tumors,primary cancer cells,and cell lines with Smad1 knockdown all showed an increase in chemosensitivity,which could be attributable to elevated p57Kip2.These findings underscore the significance of Smad1–p53 interaction in tumor suppression and reveal an unexpected role for Smad1 in chemoresistance of colorectal cancers.Xinsen Ruan Qiao Zuo Hao Jia Jenny Chau Jinlin Lin Junping Ao Xuechun Xia Huijuan Liu Samy LHabib Chuangang Fu Baojie Li 2015Journal of Molecular Cell Biology2015,7,2:2
11The circFASN/miR-33a pathway participates in tacrolimusinduced dysregulation of hepatic triglyceride homeostasis显示文摘Dyslipidemia exhibits a high incidence after liver transplantation,in which tacrolimus,a widely used immunosuppressant,plays a fundamental role.MicroRNAs and related circRNAs represent a class of noncoding RNAs that have been recognized as important regulators of genes associated with lipid metabolism.However,their transcriptional activities and functional mechanisms in tacrolimus-related dyslipidemia remain unclear.In this study,we observed that tacrolimus could induce triglyceride accumulation in hepatocytes by stimulating sterol response element-binding proteins(SREBPs)and miR-33a.Our in silico and experimental analyses identified miR-33a as a direct target of circFASN.Tacrolimus could downregulate circFASN and result in elevated miR-33a in vivo and in vitro.Overexpression of circFASN or silencing of miR-33a decreased the promoting effects of tacrolimus on triglyceride accumulation.Clinically,the incidence of dyslipidemia in liver transplant recipients with elevated serum miR-33a after liver transplantation was higher than that in patients without elevated serum miR-33a(46.3%vs.18.8%p=0.012,n=73).Our results showed that the circFASN/miR-33a regulatory system plays a distinct role in tacrolimus-induced disruption of lipid homeostasis.MiR-33a is likely a risk factor for tacrolimus-related dyslipidemia,providing a potential therapeutic target to combat tacrolimus-induced dyslipidemia after liver transplantation.Chenzhi Zhang Kangchen Chen Rongli Wei Guanghan Fan Xuechun Cai Li Xu Beini Cen Jianguo Wang Haiyang Xie Shusen Zheng Xiao Xu 2020Signal Transduction and Targeted Therapy2020,5,1:2
12Pyrolysis Characteristics and Kinetics of Methyl Oleate Based on TG-FTIR Method显示文摘The thermal decomposition characteristics of methyl oleate were preliminarily investigated under nitrogen atmosphere by a thermogravimetric analyzer when the ester was heated at a heating rate of 10 ℃/min from room temperature to 600 ℃. Furthermore, the pyrolytic and kinetic characteristics of methyl oleate were intensively studied at different heating rates. The gaseous species obtained during thermal decomposition were also identified by the TG-FTIR coupling analysis. The results showed that the pyrolysis of methyl oleate proceeded in three stages, viz. the drying stage, the main pyrolysis stage and the residual pyrolysis stage. The initial decomposition temperature, the maximum weight loss temperature, the peak decomposition temperature and the rate of maximum weight loss of methyl oleate increased with the increasing heating rates. Gaseous CO, CO2 and H2 O were the typical decomposition products from pyrolysis of methyl oleate. In addition, a kinetic model for thermal decomposition of methyl oleate was built up based on the experimental results using the CoatsRedfern integral method and the multiple-linear regression method. The activation energy, the pre-exponential factor, the reaction order and the kinetic equation for thermal decomposition of methyl oleate were obtained. Comparison of the experimental data with the calculated ones and analysis of statistical errors of pyrolysis ratios demonstrated that the kinetic model was reliable for studying the pyrolysis of methyl oleate. Finally, the kinetic compensation effect between the preexponential factors and the activation energy in the pyrolysis of methyl oleate was also confirmed.Wang Xuechun Fang Jianhua Chen Boshui Wang Jiu Wu Jiang 2015China Petroleum Processing & Petrochemical Technology2015,17,2:2
13Three-dimensional solution structure of ω-conotoxin SO_(3) determined by ^(1)H NMR显示文摘Cone snails (Conus) elaborate a series of conotoxin (CTX) peptides in their venoms to paralyze their prey. Among these toxins, w-CTX抯 specifically target to presynaptic voltage-gated calcium channel subsets, causing inhibition of neurotransmitter release. w-CTX SO3 was isolated from the venom of Conus striatus, which is the only available fish-hunting snail near the coast of the South China Sea. The three-dimensional solution structure of w-CTX SO3, a peptide which is the only w-conotoxin reported to show high homology with another w-CTX (MVIIA from C. Magus), has been determined by 1H NMR techniques. The molecular structure of w-CTX SO3 is stabilized by three disulfide bridges and a short triple-stranded antiparallel b-sheet with four turns. A comprehensive comparison suggested that the backbone conformation of w-CTXs was quite conserved, while the length of b-sheet and the type of some turns might have minor differences.YAN Yongbin TU Guangzhong LUO Xuechun DAI Qiuyun HUANG Peitang ZHANG Riqing 2003Chinese Science Bulletin2003,48,11:2
14Wavefront control of laser beam using optically addressed liquid crystal modulator显示文摘An optically addressed liquid crystal modulator for wavefront control of 1053 nm laser beam is reported in this paper.Its working principle, control method and spatial phase modulation capability are mainly introduced. A new method of measuring the relationship between gray level and phase retardation is proposed. The rationality of the curve is further confirmed by designing special experiments. According to the curve, several spatial phase distributions have been realized by this home-made device. The results show that, not only the maximum phase retardation is larger than2π for 1053 nm wavelength, but also the control accuracy is high. Compared with the liquid crystal on silicon type spatial light modulator, this kind of modulator has the advantages of generating smooth phase distribution and avoiding the black-matrix effect.Dajie Huang Wei Fan He Cheng Gang Xia Lili Pei Xuechun Li Zunqi Lin 2018High Power Laser Science and Engineering2018,6,2:2

16Cost-effectiveness analysis on COVID-19 surveillance strategy of large-scale sports competition显示文摘Background:Nucleic acid test(NAT)could effectively control the spread of COVID-19 caused by large-scale sports competitions.However,quantitative analysis on the appropriate frequency of NAT is scarce,and the cost-effectiveness and necessity of high-frequency NAT remain to be fully explored and validated.This study aims to optimize the COVID-19 surveillance strategies through cost-effectiveness analysis for the Tokyo 2020 Olympic Games and the upcoming Beijing 2022 Olympic Winter Games.Methods:A total of 18 scenarios were designed regarding the NAT frequency,symptom monitoring,and strengthening close-contact control.An agent-based stochastic dynamic model was used to compare the cost-effectiveness of different NAT scenarios and optimize the surveillance strategies.The dynamics of the proposed model included the arrival and departure of agents,transmission of the disease according to Poisson processes,and quarantine of agents based on regular NATs and symptom onset.Accumulative infections,cost,and incremental cost-effectiveness ratio(ICER)were simulated in the frame of the model.ICER was used to compare the cost-effectiveness of different scenarios.Univariate sensitivity analysis was performed to test the robustness of the results.Results:In Scenario 16,where the competition-related personnel(CRP)received NAT daily and national sports delegation(NSD)with quarantined infections accepted an additional NAT daily,accumulative infection was 320.90(90 initial infections),the total cost was(United States Dollar)USD 8920000,and the cost of detecting out each infection was USD 27800.Scenario 16 would reduce the total cost by USD 22570000(avoid 569.61 infections),USD 1420000(avoid 47.2 infections)compared with Scenario 10(weekly NAT,strengthened close contact control)and Scenario 7(daily NAT,no strengthened close contact control),respectively.Sensitivity analysis showed that the result was most sensitive to the change in basic reproductive number.Conclusions:High-frequency NATs such as bidaily,daily,and twice a day were cost-effective.NAT daily for CRP with strengthening close-contact control could be prioritized in defense against COVID-19 at large-scale sports competitions.This study could assist policymakers by assessing the cost-effectiveness of NAT scenarios and provide the host country with an optimal COVID-19 surveillance strategy.Xuechun Wang Yiru Cai Bo Zhang Xiangyu Zhang Lianhao Wang Xiangyu Yan Mingchen Zhao Yuan Zhang Zhongwei Jia 2022Infectious Diseases of Poverty2022,11,2:2
17Gas sensors based on TiO_(2) nanostructured materials for the detection of hazardous gases: A review显示文摘Hazardous gases have been strongly associated with being a detriment to human life within the environment The development of a reliable gas sensor with high response and selectivity is of great signifcance for detecting different hazardous gases.TiO_(2) nanomaterials are promising candidates with great potential and excellent per-formance in gas sensor applications,such as hydrogen,acetone,ammonia,and ethanol detection.This review begins with a detailed discussion of the di ferent dimensional morphologies of TiO_(2),whitch affect the gas sensing performance of TiO_(2) sensors.The diverse morphologies of TiO_(2) can easily be tuned by regulating the manufacturing conditions.Meanwhile,they exhibit unique characteristics for detecting gases,including large specific suface area,superior elecron tr ansport rates,extraordinary pemmeability,and active reaction sites,which offer new opportunities to improve the gas sensing properties.In addition,a variety of efforts have been made to functional TiO_(2) nanomaterials to further enhance sensing properties,including TiO_(2)-based composites and light-assisted gas sensors.The enhanced gas sensing mechanisms of multi-component composite nano-materials based on TiO_(2) include loaded noble metals,doped elements,constructed heterojunctions,and com-pounded with other functional materials.Finally,several studies have been summarized to demonstate the compar ative sensing properties of TiO_(2)-based gas sensors.Xu Tian Xiuxiu Cui Tingrun Lai Jie Ren Zhichao Yang Mingjing Xiao Bingsen Wang Xuechun Xiao Yude Wang 2021Nano Materials Science2021,3,4:1
