| 1 | Magnetism parameters characteristics of drilling deposits in Jianghan Plain and indication for forming of the Yangtze River Three Gorges显示文摘The forming time of the Yangtze River Three Gorges is considered as one of keys in the research on the Yangtze River,also is one of the most disputed hotspots.In order to solve the difficult problem,the authors adopt the internationally recognized thoughts and methods of substance tracing from source to sink.The lithologic characteristics,magnetic parameters and magnetic mineral characteristics of deposits in 2 bores are analyzed,which are both sampled from the sedimentary center of the Jianghan Plain.The results are as follows:At about 110 m depth of the core,the contents of coarse materials and stable magnetic mineral both increase significantly.Meanwhile,the magnetic susceptibility of sediment,saturation isothermal remanent magnetization and magnetic susceptibility values of anhysteretic remanent magnetism increase suddenly,which all reflect that at about 110 m depth,the important adjustment has appeared in water system of the Jianghan Plain,and the sedimentary environment and material composition have changed greatly.And it may be the horizon where the Yangtze River Three Gorges formed,its forming time reflected by the paleomagnetic dating is between 1.17 and 1.12Ma B.P. | ZHANG YuFen LI Chang'An WANG QiuLiang CHEN Liang Ma YongFa KANG ChunGuo | 2008 | Chinese Science Bulletin2008,53,4: | 34 |

| 3 | The response of annual runoff to the height change of the summertime 0℃ level over Xinjiang显示文摘According to climate features and river runoff conditions,Xinjiang could be divided into three research areas:The Altay-Tacheng region,the Tianshan Mountain region and the northern slope of the Kunlun Mountains.Utilizing daily observations from 12 sounding stations and the annual runoff dataset from 34 hydrographical stations in Xinjiang for the period 1960-2002,the variance of the summertime 0℃ level height and the changing trends of river runoff are analyzed both qualitatively and quantitatively,through trend contrast of curves processed by a 5-point smoothing procedure and linear correlation.The variance of the summertime 0℃ level height in Xinjiang correlates well with that of the annual river runoff,especially since the early 1990s,but it differs from region to region,with both the average height of the 0℃ level and runoff quantity significantly increasing over time in the Altay-Tacheng and Tianshan Mountain regions but decreasing on the northern slope of the Kunlun Mountains.The correlation holds for the whole of Xinjiang as well as the three individual regions,with a 0.01 significance level.This indicates that in recent years,climate change in Xinjiang has affected not only the surface layer but also the upper levels of the atmosphere,and this raising and lowering of the summertime 0℃ level has a direct impact on the warming and wetting process in Xinjiang and the amount of river runoff.Warming due to climate change increases the height of the 0℃ level,but also speeds up,ice-snow melting in mountain regions,which in turn increases river runoff,leading to a season of plentiful water instead of the more normal low flow period. | ZHANG Guangxing SUN Shufang MA Yufen ZHAO Ling | 2010 | Journal of Geographical Sciences2010,20,6: | 10 |
| 4 | Long-term trends in fog and boundary layer characteristics in Tianjin,China显示文摘Long-term trends in fog episodes,vertical variations of atmospheric boundary structure,and air pollutant concentrations during two different heavy fog events in the Tianjin area were analyzed.The total amount of fog has increased since 1980 due to the stability of the boundary layer and an increase of pollutant emissions.The variation in the characteristics of the boundary layer and air pollutant concentrations were significantly different between the two fog processes(fog 1 and fog II).The onset of fog I was accompanied by a temperature inversion in the low atmosphere,and the average kinetic energy showed a clear diurnal trend and vertical variation,which increased with height.The dissipation of fog I was mainly due to turbulence.However,the atmospheric stratification was not stable in the lower layer before the onset of fog II.The diurnal and vertical changes in kinetic energy were very small,in which turbulent momentum at each measurement height tended to be zero.In the dissipation process of fog II,wind speed increased significantly.Surface PM_(2.)5 concentrations decreased,but the ratio of PM_(2.5) to PM_(10)increased from 0.66 to 0.82 until fog I dissipated.However,the concentration of PM2.5 did not decrease at the early stage of fog II,but the ratio of PM_(2.5) to PM_(10) PM_(2.5)/PM_(10) decreased to 0.21 when fog II dissipated.This study showed that there was a clear difference in the evolution of pollutant concentration for different pollutants and in different developing stages during the fog events.PM2.5 concentration accumulated faster than those of SO_2 and NO_x,and the PM_(2.5) cumulative rate was greater in the mid-term of the fog process. | Suqin Han Ziying Cai Yufen Zhang Jiao Wang Qing Yao Peiyan Li Xiangjin Li | 2015 | Particuology2015,13,3: | 7 |
| 5 | An individualized immune signature of pretreatment biopsies predicts pathological complete response to neoadjuvant chemoradiotherapy and outcomes in patients with esophageal squamous cell carcinoma显示文摘No clinically available biomarkers can predict pathological complete response(pCR)for esophageal squamous cell carcinomas(ESCCs)with neoadjuvant chemoradiotherapy(nCRT).Considering that antitumor immunity status is an important determinant for nCRT,we performed an integrative analysis of immune-related gene profiles from pretreatment biopsies and constructed the first individualized immune signature for pCR and outcome prediction of ESCCs through a multicenter analysis.During the discovery phase,14 differentially expressed immune-related genes(DEIGs)with greater than a twofold change between pCRs and less than pCRs( | Chaoqi Zhang Guochao Zhang Nan Sun Zhen Zhang Liyan Xue Zhihui Zhang Haijun Yang Yuejun Luo Xiaoli Zheng Yonglei Zhang Yufen Yuan Ruixue Lei Zhaoyang Yang Bo Zheng Le Wang Yun Che Feng Wang Sihui Wang Shugeng Gao Qi Xue Yi Zhang Jie He | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 7 |

| 8 | Vertical characteristics and source identification of PM_(10) in Tianjin显示文摘Ambient PM 10 (particulate matter with a diameter less than 10μm) concentrations were measured on a 255 meter tower in Tianjin,China.The samples were collected at four vertical levels (10,40,120 and 220 m).Vertical characteristics for PM 10 samples were studied.The results showed that the concentrations of PM 10 and constituent species had a negative correlation with the sampling height.The highest concentrations of PM 10 and species were obtained at the 10 m level,and the lowest concentrations were measured at the 220 m level.For the fractions of species to total mass,SO 4 2- and NO 3- had higher values (fraction) at greater height;while Ca had a higher fraction at lower height.Possible source categories for the PM 10 ambient dataset were identified by the principal component analysis method.The possible source categories included crustal dust,vehicles,cement dust,and incineration as well as secondary sulfate and nitrate sources.Analysis of meteorological factors on PM 10 concentrations indicated that wind speed and inversion may be the main factors contributing to different concentrations of PM 10 at different heights. | Zhimei Xiao Jianhui Wu Suqin Han Yufen Zhang Hong Xu Xiaoyong Zhang Guoliang Shi Yinchang Feng | 2012 | Journal of Environmental Sciences2012,24,1: | 5 |

| 11 | Impact of meteorological condition changes on air quality and particulate chemical composition during the COVID-19 lockdown显示文摘Stringent quarantine measures during the Coronavirus Disease 2019(COVID-19)lockdown period(January 23,2020 to March 15,2020)have resulted in a distinct decrease in anthropogenic source emissions in North China Plain compared to the paralleled period of 2019.Particularly,22.7%decrease in NO_(2)and 3.0%increase of O_(3)was observed in Tianjin,nonlinear relationship between O_(3)generation and NO_(2)implied that synergetic control of NOx and VOCs is needed.Deteriorating meteorological condition during the COVID-19 lockdown obscured the actual PM2.5 reduction.Fireworks transport in 2020 Spring Festival(SF)triggered regional haze pollution.PM2.5 during the COVID-19 lockdown only reduced by 5.6%in Tianjin.Here we used the dispersion coefficient to normalize the measured PM2.5(DN-PM2.5),aiming to eliminate the adverse meteorological impact and roughly estimate the actual PM2.5 reduction,which reduced by 17.7%during the COVID-19 lockdown.In terms of PM2.5 chemical composition,significant NO_(3)−increase was observed during the COVID-19 lockdown.However,as a tracer of atmospheric oxidation capacity,odd oxygen(Ox=NO_(2)+O_(3))was observed to reduce during the COVID-19 lockdown,whereas relative humidity(RH),specific humidity and aerosol liquid water content(ALWC)were observed with noticeable enhancement.Nitrogen oxidation rate(NOR)was observed to increase at higher specific humidity and ALWC,especially in the haze episode occurred during 2020SF,high air humidity and obvious nitrate generation was observed.Anomalously enhanced air humidity may response for the nitrate increase during the COVID-19 lockdown period. | Jing Ding Qili Dai Yafei Li Suqin Han Yufen Zhang Yinchang Feng | 2021 | Journal of Environmental Sciences2021,33,11: | 2 |
| 12 | Size distribution and chemical characteristics of particles from crop residue open burning in North China显示文摘Crop residue open burning is an important emission source of ambient particles in China.This study analyzed the particle emission characteristics of crop residue open burning through combustion experiments with a novel open combustion simulation device using three typical crop straws in north China(corn,wheat,and rice).Particle samples size ranging from 0.006–9.890μm were collected by an Electrical Low Pressure Impactor plus,a high size-resolution instrument capable of dividing particles into 14 size stages.The size distributions of organic carbon(OC),elemental carbon(EC),water-soluble ions,and elements were analyzed,and source chemical profiles were constructed for PM0.1,PM1,PM2.5,and PM10.The number concentration of particles was concentrated in the Aiken nuclei mode(0.006–0.054μm),accounting for 75%of the total number,whereas the mass concentration was concentrated in the accumulation mode(0.054–0.949μm),accounting for 85.43%of the mass loading.OC,EC,Cl−,and K(include total K and water-soluble K)were the major chemical components of the particles,whose mass percentage distributions differed from those of other components.These fivemain components exhibited a bell-shaped size distribution in the 0.006–9.890μm range,whereas the other components exhibited a U-shaped distribution.Among the chemical profiles for PM0.1–PM10,OC was the most important component at 10–30%,followed by EC at 2%–8%.The proportions of K^(+),Cl^(−),and K varied substantially in different experimental groups,ranging from 0–15%,and K+and Cl−were significantly correlated(r=0.878,α=0.000). | Tingkun Li Qili Dai Xiaohui Bi Jianhui Wu Yufen Zhang Yinchang Feng | 2021 | Journal of Environmental Sciences2021,33,11: | 2 |

| 15 | Suppression of ETI by PTI priming to balance plant growth and defense through an MPK3/MPK6-WRKYs-PP2Cs module显示文摘Pattern-triggered immunity(PTI)and effector-triggered immunity(ETI)are required for host defense against pathogens.Although PTI and ETI are intimately connected,the underlying molecular mechanisms remain elusive.In this study,we demonstrate that flg22 priming attenuates Pseudomonas syringae pv.tomato DC3000(Pst)AvrRpt2-induced hypersensitive cell death,resistance,and biomass reduction in Arabidopsis.Mitogen-activated protein kinases(MAPKs)are key signaling regulators of PTI and ETI.The absence of MPK3 and MPK6 significantly reduces pre-PTI-mediated ETI suppression(PES).We found that MPK3/MPK6 interact with and phosphorylate the downstream transcription factor WRKY18,which regulates the expression of AP2C1 and PP2C5,two genes encoding protein phosphatases.Furthermore,we observed that the PTI-suppressed ETI-triggered cell death,MAPK activation,and growth retardation are significantly attenuated in wrky18/40/60 and ap2c1 pp2c5 mutants.Taken together,our results suggest that the MPK3/MPK6-WRKYs-PP2Cs module underlies PES and is essential for the maintenance of plant fitness during ETI. | Dacheng Wang Lirong Wei Ting Liu Jinbiao Ma Keyi Huang Huimin Guo Yufen Huang Lei Zhang Jing Zhao Kenichi Tsuda Yiming Wang | 2023 | Molecular Plant2023,16,5: | 1 |

| 18 | Asexual and sexual reproductive strategies in clonal plants显示文摘Most plants can reproduce both sexually and asexually(or vegetatively),and the balance between the two reproductive modes may vary widely between and within species.Extensive clonal growth may affect the evolution of life history traits in many ways.First,in some clonal species,sexual reproduction and sex ratio vary largely among popula-tions.Variation in sexual reproduction may strongly affect plant’s adaptation to local environments and the evolution of the geographic range.Second,clonal growth can increase floral display,and thus pollinator attraction,while it may impose serious constraints and evolutionary challenges on plants through geitonogamy that may strongly influence pollen dispersal.Geitonogamous pollination can bring a cost to plant fitness through both female and male functions.Some co-evolutionary interactions,therefore,may exist between the spatial structure and the mating behavior of clonal plants.Finally,a trade-off may exist between sexual reproduction and clonal growth.Resource allocation to the two reproduc-tive modes may depend on environmental conditions,com-petitive dominance,life span,and genetic factors.If different reproductive modes represent adaptive strategies for plants in different environments,we expect that most of the resources should be allocated to sexual reproduction in habitats with fluctuating environmental conditions and strong competition,while clonal growth should be dominant in stable habitats.Yet we know little about the consequence of natural selection on the two reproductive modes and factors which control the balance of the two reproductive modes.Future studies should investigate the reproductive strategies of clonal plants simultaneously from both sexual and asexual perspectives. | ZHANG Yufen ZHANG Dayong | 2007 | Frontiers in Biology2007,2,3: | 1 |
