1Effect of urbanization on the winter precipitation distribution in Beijing area显示文摘According to the urbanization extent of Beijing area, and with 1980 as a turning point, the duration from 1961 to 2000 is divided into two periods: one is defined as the slow urbanization period from 1961 to 1980, and other one as the fast urbanization period from 1981 to 2000. Based on the 40-year’s precipi-tation data of 14 standard weather stations in Beijing area, the effect of urbanization on precipitation distribution is studied. It is found that there has been a noticeable and systematic change of winter precipitation distribution pattern between these two periods in Beijing area: in the slow urbanization period, the precipitation in the southern part of Beijing is more than that in the northern part; but in the fast urbanization period, the precipitation distribution pattern is reverse, i.e. the precipitation in the southern part is less than that in the northern part; But in other seasons, the precipitation distribution pattern did not change remarkably in general. The possible cause resulting in the change of winter precipitation distribution pattern, might be that with urban area extension, the effects of 'urban heat island' and 'urban dry island' become more and more intensified, and increase hydrometeors evapo-ration below precipitable cloud, and then cause less precipitation received on the ground surface in the downtown and the southern part. It is also noteworthy to further research why the precipitation distri-bution pattern does not change systematically in other seasons except winter after intense urbaniza-tion in Beijing area.WANG XiQuan WANG ZiFa QI YanBin GUO Hu 2009Science China Earth Sciences2009,52,2:13
2Characteristics of Tight Sandstone Reservoirs and Controls of Reservoir Quality: A Case Study of He 8 Sandstones in the Linxing Area, Eastern Ordos Basin, China显示文摘Determining the process of densification and tectonic evolution of tight sandstone can help to understand the distribution of reservoirs and find relatively high-permeability areas.Based on integrated approaches of thin section,scanning electron microscopy(SEM),cathode luminescence(CL),nuclear magnetic resonance(NMR),X-ray diffraction(XRD),N2 porosity and permeability,micro-resistivity imaging log(MIL)and three-dimensional seismic data analysis,this work discussed the reservoir characteristics of the member 8 of the Permian Xiashihezi Formation(He 8 sandstones)in the Linxing area of eastern Ordos Basin,determined the factors affecting reservoir quality,and revealed the formation mechanism of relatively high-permeability areas.The results show that the He 8 sandstones in the Linxing area are mainly composed of feldspathic litharenites,and are typical tight sandstones(with porosity<10%and permeability<1 mD accounting for 80.3%of the total samples).Rapid burial is the main reason for reservoir densification,which resulted in 61%loss of the primary porosity.In this process,quartz protected the original porosity by resisting compaction.The cementation(including carbonate,clay mineral and siliceous cementation)further densified the sandstone reservoirs,reducing the primary porosity with an average value of 28%.The calcite formed in the eodiagenesis occupied intergranular pores and affected the formation of the secondary pores by preventing the later fluid intrusion,and the Fe-calcite formed in the mesodiagenetic stage densified the sandstones further by filling the residual intergranular pores.The clay minerals show negative effects on reservoir quality,however,the chlorite coatings protected the original porosity by preventing the overgrowth of quartz.The dissolution of feldspars provides extensive intergranular pores which constitute the main pore type,and improves the reservoir quality.The tectonic movements play an important role in improving the reservoir quality.The current tectonic traces of the study area are mainly controlled by the Himalayan movement,and the high-permeability reservoirs are mainly distributed in the anticline areas.Additionally,the improvement degree(by tectonic movements)of reservoir quality is partly controlled by the original composition of the sandstones.Thus,the selection of potential tight gas well locations in the study area should be focused on the anticline areas with relatively good original reservoir quality.And the phenomena can be referenced for other fluvial tight sandstone basins worldwide.GAO Xiangdong WANG Yanbin LI Yong GUO Hui NI Xiaoming WU Xiang ZHAO Shihu 2019Acta Geologica Sinica(English Edition)2019,93,3:5
3Design and application of 60mer oligonucleotide microarray in SARS coronavirus detection显示文摘The 60mer oligonucleotide microarray was designed and applied to detecting of SARS (severe acute res-piratory syndrome) coronavirus. Thirty 60mer specific oligos were designed to cover the whole genome of the first submit-ted coronavirus strain, according to the sequence of TOR2 (GENEBANK Accession: AY274119). These primers were synthesized and printed into a microarray with 12×12 spots. RNAs were extracted from the throat swab and gargling fluid of SARS patients and reverse-transcripted into the double strand cDNAs. The cDNAs were prepared as re-stricted cDNA fragments by the restriction display (RD) technique and labeled by PCR with the Cy5-universal primer. The labeled samples were then applied to the oligo microar-ray for hybridization. The diagnostic capability of the mi-croarray was evaluated after the washing and scanning steps. The scanning result showed that samples of SARS patients were hybridized with multiple SARS probes on the microar-ray, and there is no signal on the negative and blank controls. These results indicate that the genome of SARS coronavirus can be detected in parallel by the 60mer oligonucleotide mi-croarray, which can improve the positive ratio of the diagno-sis. The oligo microarray can also be used for monitoring the behavior of the virus genes in different stages of the disease status.SHI Rong MA Wenli WU Qinghua ZHANG Bao SONG Yanbin GUO Qiuye XIAO Weiwei WANG Yan ZHENG Wenling 2003Chinese Science Bulletin2003,48,12:4
4Stable Lithium-Carbon Composite Enabled by Dual-Salt Additives显示文摘Lithium metal is regarded as the ultimate negative electrode material for secondary batteries due to its high energy density.However,it suffers from poor cycling stability because of its high reactivity with liquid electrolytes.Therefore,continuous efforts have been put into improving the cycling Coulombic efficiency(CE)to extend the lifespan of the lithium metal negative electrode.Herein,we report that using dual-salt additives of LiPF_(6) and LiNO_(3) in an ether solvent-based electrolyte can significantly improve the cycling stability and rate capability of a Li-carbon(Li-CNT)composite.As a result,an average cycling CE as high as 99.30% was obtained for the Li-CNT at a current density of 2.5 mA cm^(-2) and an negative electrode to positive electrode capacity(N/P)ratio of 2.The cycling stability and rate capability enhancement of the Li-CNT negative electrode could be attributed to the formation of a better solid electrolyte interphase layer that contains both inorganic components and organic polyether.The former component mainly originates from the decomposition of the LiNO_(3) additive,while the latter comes from the LiPF_(6)-induced ring-opening polymerization of the ether solvent.This novel surface chemistry significantly improves the CE of Li negative electrode,revealing its importance for the practical application of lithium metal batteries.Lei Zheng Feng Guo Tuo Kang Yingzhu Fan Wei Gu Yayun Mao Ya Liu Rong Huang Zhiyun Li Yanbin Shen Wei Lu Liwei Chen 2021Nano-Micro Letters2021,13,7:3
5Finger or Light:Stimulation Sensitivity of Visual Startle in the Coma Recovery Scale-Revised for Disorders of Consciousness显示文摘Dear Editor,Coma,the vegetative state(VS),and the minimallyconscious state(MCS),often collectively referred to as disorders of consciousness(DOCs),typically occur after severe traumatic or non-traumatic brain injury^([1]).The boundary between awareness and unawareness remains elusive,making it difficult to correctly distinguish MCS from VS patients.It is possible to employ noninvasive neuroimaging techniques,such as functional MRI(f MRI)[2]to assess residual cognitive processing as wellFeng Zhou Hui Li Kai Wang Yanbin He Yan Chen Xiaoxiao Ni Yechun Guo Wei Lv Jiechun Zhang Qiuyou Xie Ronghao Yu 2018Neuroscience Bulletin2018,34,4:3
6Genetically modified CD7-targeting allogeneic CAR-T cell therapy with enhanced efficacy for relapsed/refractory CD7-positive hematological malignancies:a phase I clinical study显示文摘Chimeric antigen receptor(CAR)-T cell therapy against T cell malignancies faces major challenges including fratricide between CAR-T cells and product contamination from the blasts.Allogeneic CAR-T cells,generated from healthy donor T cells,can provide ready-to-use,blast-free therapeutic products,but their application could be complicated by graft-versus-host disease(GvHD)and host rejection.Here we developed healthy donor-derived,CD7-targeting CAR-T cells(RD13-01)with genetic modifications to resist fratricide,GvHD and allogeneic rejection,as well as to potentiate antitumor function.A phase I clinical trial(NCT04538599)was conducted with twelve patients recruited(eleven with T cell leukemia/lymphoma,and one with CD7-expressing acute myeloid leukemia).All patients achieved pre-set end points and eleven proceeded to efficacy evaluation.No dose-limiting toxicity,GvHD,immune effector cell-associated neurotoxicity or severe cytokine release syndrome(grade≥3)were observed.28 days post infusion,81.8%of patients(9/11)showed objective responses and the complete response rate was 63.6%(7/11,including the patient with AML).3 of the responding patients were bridged to allogeneic hematopoietic stem cell transplantation.With a median follow-up of 10.5 months,4 patients remained in complete remission.Cytomegalovirus(CMV)and/or Epstein-Barr virus(EBV)reactivation was observed in several patients,and one died from EBV-associated diffuse large B-cell lymphoma(DLBCL).Expansion of CD7-negative normal T cells was detected post infusion.In summary,we present the first report of a Phase I clinical trial using healthy donor-derived CD7-targeting allogeneic CAR-T cells to treat CD7^(+)hematological malignancies.Our results demonstrated the encouraging safety and efficacy profiles of the RD13-01 allogeneic CAR-T cells for CD7^(+)tumors.Yongxian Hu Yali Zhou Mingming Zhang Houli Zhao Guoqing Wei Wengang Ge Qu Cui Qitian Mu Gong Chen Lu Han Tingting Guo Jiazhen Cui Xiaoyan Jiang Xiujun Zheng Shuhui Yu Xiaolong Li Xingwang Zhang Mingxi Chen Xiuju Li Ming Gao Kang Wang Cheng Zu Hao Zhang Xiaohong He Yanbin Wang Dongrui Wang Jiangtao Ren He Huang 2022Cell Research2022,32,11:2

8Highly stable lithium anode enabled by self-assembled monolayer of dihexadecanoalkyl phosphate显示文摘Li has been considered as the ultimate anode material for high energy density secondary Li batteries.However,its practical application has been limited due to its low Coulombic efficiency(CE)and the formation of lithium dendrites.Recently,we have developed a microspherical Li-carbon nanotube(Li-CNT)composite material passivated with octadecylphosphonic acid(OPA)self-assembled monolayer(SAM)exhibiting suppressed lithium dendrite formation and improved environmental/electrochemical stability.In this work,we demonstrated the significantly enhanced passivation effects of a SAM using dihexadecanoalkyl phosphate(DHP),a molecule that is comprised of double hydrophobic alkyl chains and forms a denser SAM on surfaces with large curvature.As a result,the DHP SAM delivers superior environmental and electrochemical stability to the OPA passivated Li-CNT material.In specific,the DHP passivated Li-CNT composite(DHP-Li-CNT)delivers a high CE of 99.25%under a 33.3%depth of discharge(DOD)at 1 C,when it is paired with a LiFePO4 cathode.The evolution of the SAM during cycling and the effects of DOD and current density on the CE of the DHP-Li-CNT anode have also been investigated.The improved SAM passivation constitutes an important step in achieving the goal of practically applicable Li anodes.Lei Zheng Feng Guo Tuo Kang Jin Yang Ya Liu Wei Gu Yanfei Zhao Hongzhen Lin Yanbin Shen Wei Lu Liwei Chen 2020Nano Research2020,13,5:1

17基于碳-水-氮耦合过程改进模型的温带草地生态系统生产力模拟研究显示文摘预测气候变化背景下生态系统总初级生产力的响应是全球变化生态学研究领域的一项核心任务。然而,对模型研究领域来说,准确模拟干旱生态系统总初级生产力的年际变异仍然是一个巨大的挑战。土壤含水量和总初级生产力对土壤水敏感性的精确模拟,是预测干旱生态系统中总初级生产力年际变异的两个关键方面。为此,本研究以一个广泛应用的生态系统模型(Biome-BGC模型)为例,旨在改进温带草地生态系统的模型模拟效果。一方面,通过对蒸散模块、土壤水沿剖面的垂直分布和田间持水量计算的改进和调整,模型实现了对土壤水模拟的更新。另一方面,我们改进了影响水-氮关系的函数,从而调节了总初级生产力对土壤水的敏感性。研究结果表明,原有模型高估了土壤含水量,低估了总初级生产力敏感性的年际变异,从而导致模拟总初级生产力的年际变异低于观测值。例如,原模型严重低估了总初级生产力在干旱年份的减少。相比之下,改进后的模型准确地模拟了观测土壤水的季节和年际变化,特别是表层土壤水。通过优化影响氮矿化的参数,改进后的模型改善了总初级生产力对土壤水敏感性的模拟,使其更接近观测值。因此,改进后模型对总初级生产力年际变异的模拟得到了很大程度的提高。我们的结果表明,在对干旱生态系统总初级生产力年际变异进行模拟时,应优先考虑表层土壤水及其对氮有效性的影响。Kaili Cheng Zhongmin Hu Shenggong Li Qun Guo Yanbin Hao Wenping Yuan 2021Journal of Plant Ecology2021,14,1:0
18Integrated genetic linkage map of cultivated peanut by three RIL populations显示文摘High-density and precise genetic linkage map is fundamental to detect quantitative trait locus (QTL) of agronomic and quality related traits in cultivated peanut (Arachis hypogaea L.). In this study, three linkage maps from three RIL (recombinant inbred line)populations were used to construct an integrated map. A total of 2,069 SSR and transposon markers were anchored on the high-density integrated map which covered 2,231.53 cM with 20 linkage groups. Totally, 92 QTLs correlating with pod length (PL), pod width (PW), hundred pods weight (HPW) and plant height (PH) from above RIL populations were mapped on it. Seven intervals were found to harbor QTLs controlling the same traits in different populations,including one for PL, three for PW, two for HPW, and one for PH. Besides, QTLs controlling different traits in different populations were found to be overlapped in four intervals.Interval on A05 contains 17 QTLs for different traits from two RIL populations. New markers were added to these intervals to detect QTLs with narrow confidential intervals.Results obtained in this study may facilitate future genomic researches such as QTL study, fine mapping, positional cloning and marker-assisted selection (MAS) in peanut.Yanbin Song Huaiyong Luo Li Huang Yuning Chen Weigang Chen Nian Liu Xiaoping Ren Bolun Yu Jianbin Guo Huifang Jiang 2017Oil Crop Science2017,2,3:0
19National incidence of joint dislocation in China:a retrospective survey of 512,187 individuals显示文摘Background:Joint dislocations significantly impact public health.However,a comprehensive study on the incidence,distribution,and risk factors for joint dislocations in China is lacking.We conducted the China National Joint Dislocation Study,which is a part of the China National Fracture Study conducted to obtain the national incidence and risk factors for traumatic fractures,and to investigate the incidence and risk factors for joint dislocations.Methods:For this national retrospective epidemiological study,512,187 participants were recruited using stratified random sampling and probability-proportional-to-size method from January 19 to May 16,2015.Participants who sustained joint dislocations of the trunk,arms,or legs(skull,sternum,and ribs being excluded)in 2014 were personally interviewed to obtain data on age,educational background,ethnic origin,occupation,geographic region,and urbanization degree.The joint-dislocation incidence was calculated based on age,sex,body site,and demographic factors.The risk factors for different groups were examined using multiple logistic regression.Results:One hundred and nineteen participants sustained 121 joint dislocations in 2014.The population-weighted incidence rate of joint dislocations of the trunk,arms,or legs was 0.22(95%confidence interval[CI]:0.16,0.27)per 1000 population in 2014(men,0.27[0.20,0.34];women,0.16[0.10,0.23]).For all ages,previous dislocation history(male:OR 42.33,95%confidence interval[CI]:12.03-148.90;female:OR 54.43,95%CI:17.37-170.50)and alcohol consumption(male:OR 3.50,95%CI:1.49-8.22;female:OR 2.65,95%CI:1.08-6.50)were risk factors for joint dislocation.Sleeping less than 7 h/day was a risk factor for men.Compared with children,women aged≥15 years(female 15-64 years:OR 0.16,95%CI:0.04-0.61;female≥65 years:OR 0.06,95%CI:0.01-0.41)were less likely to sustain joint dislocations.Women with more than three children were at higher dislocation risk than women without children(OR 6.92,95%CI:1.18-40.78).Conclusions:The up-to-date data on joint dislocation incidence,distribution,and risk factors can be used as a reference for national healthcare,prevention,and management in China.Specific strategies for decreasing alcohol consumption and encouraging adequate sleeping hours should be developed to prevent or reduce dislocation incidents.Trial Registration:Chinese Clinical Trial Registry,ChiCTR-EPR-15005878.Hongzhi Lv Wei Chen Zhiyong Hou Siming Jia Yanbin Zhu Bo Liu Xiao Chen Guang Yang Lei Liu Tao Zhang Haili Wang Bing Yin Song Liu Jialiang Guo Xiaolin Zhang Yichong Li Yingze Zhang 2022Chinese Medical Journal2022,,14:0
