| 1 | Ecological restoration and recovery in the wind-blown sand hazard areas of northern China: relationship between soil water and carrying capacity for vegetation in the Tengger Desert显示文摘The main prevention and control area for wind-blown sand hazards in northern China is about 320000 km2 in size and includes sandlands to the east of the Helan Mountain and sandy deserts and desert-steppe transitional regions to the west of the Helan Mountain.Vegetation recovery and restoration is an important and effective approach for constraining wind-blown sand hazards in these areas.After more than 50 years of long-term ecological studies in the Shapotou region of the Tengger Desert,we found that revegetation changed the hydrological processes of the original sand dune system through the utilization and space-time redistribution of soil water.The spatiotemporal dynamics of soil water was significantly related to the dynamics of the replanted vegetation for a given regional precipitation condition.The long-term changes in hydrological processes in desert areas also drive replanted vegetation succession.The soil water carrying capacity of vegetation and the model for sand fixation by revegetation in aeolian desert areas where precipitation levels are less than 200 mm are also discussed. | LI XinRong ZHANG ZhiShan TAN HuiJuan GAO YanHong LIU LiChao WANG XinPing | 2014 | Science China(Life Sciences)2014，57，5： | 39 |
| 2 | Simulation of rainfall-runoff and watershed convergence process in the upper reaches of Heihe River Basin,July 2002显示文摘The watershed flow concentration scheme in the distributed hydrology-soil- vegetation model (DHSVM) is coupled with the mesoscale atmospheric model MM5 version 3.5, in which the Oregen States University land surface model (OSULSM) was involved. The flood event which happened in July 2002 in the upper reaches of Heihe river basin is simulated and the surface flow convergence process is shown with this coupled model. It has been concluded that times water head reaches each place of the basin are different. Water amount at each point is split-flow proportionally as the drops in elevation between it and neighbor points. Large part of the water amount pass away in greater slope direction and small part pass away in smaller slope one.Adding of the slope convergence makes the atmospheric model redistributes the surface water laterally. | GAO Yanhong L(U) Shihua CHENG Guodong | 2004 | Science China Earth Sciences2004，47，z1： | 13 |
| 3 | Soil water repellency and influencing factors of Nitraria tangutorun nebkhas at different succession stages显示文摘Soil water repellency(WR) is an important physical characteristic of soil surface. It is capable of largely influencing the hydrological and geomorphological processes of soil, as well as affecting the ecological processes of plants, such as growth and seed germination, and has thus been a hot topic in recent research around the world. In this paper, the capillary rise method was used to study the soil WR characteristics of Nitraria tangutorun nebkhas. Soil water repellencies at different succession stages of Nitraria tangutorun were investigated, and the relationships between soil WR and soil organic matter, total N, and total P, soil texture, pH, and concentrations of CO3 2-, HCO3-, Cl-, SO4 2-, Na+, K+, Ca2+and Mg2+were discussed. Soil WR may be demonstrated at the following nebkhas dune evolvement stages: extremely degraded>degraded>stabilized>well developed>newly developed>quick sand. Apart from some soil at the bottom, the WR of other soils(crest and slope of dune) was found to be largest at the topsoil, and decreased as the soil depth increased. The results showed that multiple factors affected soil WR characteristics, e.g. WR increased significantly as the contents of soil organic matter and total N increased, but did not change as the total P content increased. Soil texture was a key factor affecting soil WR; soil WR increased significantly as clay content increased, and decreased significantly as sand content increased. Low pH was shown to be more suitable for the occurrence of soil WR. Four cations(Ca2+, Mg2+, K+and Na+) and two anions(Cl-and SO4 2-) enhanced soil WR, while CO3 2-decreased it. HCO3-did not show any observable effect. Finally, we established a best-fit general linear model(GLM) between soil-air-water contact angle(CA) and influencing factors(CA=5.606 sand+6.496(clay and silt)–2.353 pH+470.089 CO3 2-+11.346 Na+–407.707 Cl-–14.245 SO4 2-+0.734 total N–519.521). It was concluded that all soils contain subcritical WR(0° | HaoTian YANG XinRong LI LiChao LIU YanHong GAO Gang LI RongLiang JIA | 2014 | Journal of Arid Land2014，6，3： | 9 |

| 5 | Mycorrhizal fungal community composition in seven orchid species inhabiting Song Mountain, Beijing, China显示文摘Mycorrhizal fungi play an important role in the germination and growth of orchids essentially influencing their survival,abundance, and spatial distribution. In this study, we investigated the composition of the mycorrhizal fungal community in seven terrestrial orchid species inhabiting Song Mountain, Beijing, China, using Illumina MiSeq high-throughput sequencing. The mycorrhizal communities in the seven orchids were mainly composed of members of the Ceratobasidiaceae, Sebacinales, and Tulasnellaceae, while a number of ectomycorrhizal fungi belonging to the Russulaceae, Tricholomataceae, Thelephoraceae, and Cortinariaceae were occasionally observed. However, the dominant fungal associates and mycorrhizal community differed significantly among the orchid species as well as subhabitats. These findings confirm the previous observation that sympatric orchid species show different preferences for mycorrhizal fungi, which may drive niche partitioning and contribute to their cooccurrence. | Yanhong Chen Yue Gao Linli Song Zeyu Zhao Shunxing Guo Xiaoke Xing | 2019 | Science China(Life Sciences)2019，62，6： | 6 |
| 6 | Precise temporal regulation of Dux is important for embryo development显示文摘Dear Editor,Zygotic genome activation(ZGA)following fertilization is accomplished through a process termed the maternal-to-zygotic transition,during which the maternal RNAs and proteins are degraded and zygotic genome is transcriptionally activated.In mice,minor ZGA occurs from S phase of the zygote to G1 phase of the two-cell(2C)embryo,while major ZGA takes place during the middle-to-late 2C stage with a burst of transcription of totipotent cleavage stage-specific genes and retrotransposons. | Mingyue Guo Yanping Zhang Jianfeng Zhou Yan Bi Junqin Xu Ce Xu Xiaochen Kou Yanhong Zhao Yanhe Li Zhifen Tu Kuisheng Liu Jiaming Lin Peng Yang Shaorong Gao Yixuan Wang | 2019 | Cell Research2019，29，11： | 5 |
| 7 | Nuclear m^(6)A reader YTHDC1 regulates the scaffold function of LINE1 RNA in mouse ESCs and early embryos显示文摘N^(6)-methyladenosine(m^(6)A)on chromosome-associated regulatory RNAs(carRNAs),including repeat RNAs,plays important roles in tuning the chromatin state and transcription,but the intrinsic mechanism remains unclear.Here,we report that YTHDC1 plays indispensable roles in the self-renewal and differentiation potency of mouse embryonic stem cells(ESCs),which highly depends on the m^(6)A-binding ability.Ythdcl is required for sufficient rRNA synthesis and repression of the 2-cell(2C)transcriptional program in ESCs,which recapitulates the transcriptome regulation by the LINE1 scaffold.Detailed analyses revealed that YTHDC1 recognizes m^(6)A on LINE1 RNAs in the nucleus and regulates the formation of the LINE1-NCL partnership and the chromatin recruitment of KAP1.Moreover,the establishment of H3K9me3 on 2C-related retrotrans-posons is interrupted in Ythdcl-depleted ESCs and inner cell mass(ICM)cells,which consequently increases the transcriptional activities.Our study reveals a role of m^(6)A in regulating the RNA scaffold,providing a new model for the RNA-chromatin cross-talk. | Chuan Chen Wenqiang Liu Jiayin Guo Yuanyuan Liu Xuelian Liu Jun Liu Xiaoyang Dou Rongrong Le Yixin Huang Chong Li Lingyue Yang Xiaochen Kou Yanhong Zhao You Wu Jiayu Chen Hong Wang Bin Shen Yawei Gao Shaorong Gao | 2021 | Protein & Cell2021，12，6： | 4 |
| 8 | Near-infrared fluorescent amphiphilic polycation wrapped magnetite nanoparticles as multimodality probes显示文摘Construction of multifunctional/multimodality nanoparticles for cancer diagnosis and therapy has become an attractive area of investigation. In this report, we designed a multimodality nanoprobe for cell labeling, and can be detectable by both magnetic resonance and near infrared (NIR) fluorescence imaging. Multiple hydrophobic superparamagnetic iron oxide (SPIO) nanocrystals are self-assembled into nanocomposites in water phase with the help of partially alkylated hyperbranched polycation, polyethylenimine (PEI), which already conjugated with the indocyanine dye Cy5.5 and can be used for cell imaging under NIR fluorescence imaging. The amphiphilic PEI/SPIO nanocomposites have a strong T 2 relaxivity. The iron uptake process in MCF-7/Adr displays a time dependent behavior. Confocal laser scanning microscopy reveals that the nanoprobes are internalized into the cytoplasm of MCF-7/Adr after 24 h labeling. Both MR and NIR fluorescence imaging showed strong image contrast against unlabeled cells. Under a clinical MRI scanner, labeled cells in gelatin phantom present much darker images than controlled ones. The T2 relaxation rate of the labeled cells is 98.2 s 1 , significantly higher than that of the control ones of 2.3 s 1 . This study provides an important alternative to label MCF-7/Adr at optimized low dosages with high efficiency, and may be useful to label other biologically important cells and track their behaviors in vivo. | WANG Dan SU HongYing LIU yanHong WU ChangQiang XIA ChunChao SUN JiaYu GAO FaBao GONG QiYong SONG Bin AI Hua | 2012 | Chinese Science Bulletin2012，57，31： | 4 |
| 9 | On transitioning from PID to ADRC in thermal power plants显示文摘This paper focuscs on the recent progress in the adoption of active disturbance rejection control(ADRC)in thermal pro-cesses as a viable alternative to proportional-_integral-derivative(PID),especially in coa-fired power plants.The profound interpretation of this paradigm shift,with backward compatibility,is discussed in detail.A few fundamental issues associated with ADRC's applications in thermal processes are discussed,such as implementation,tuning,and the structural changes.Examples and case studies are presented,encompassing coal-fired power plants,gas turbines and nuclear power plants,as well as highlighting results of field applications.Also discussed are future research opportunities brought by ADRC's entry as the baseline control technology in thermal processes. | Zhenlong Wu Zhiqiang Gao Donghai Li YangQuan Chen Yanhong Liu | 2021 | Control Theory and Technology2021，19，1： | 4 |
| 10 | Anti-β2GPI/β2GPI complexes induce platelet activation and promote thrombosis via p38MAPK: a pathway to targeted therapies显示文摘Anti-β2 glycoprotein I(anti-β2GPI)antibodies are important contributors to the development of thrombosis.Anti-β2GPI antibody complexes withβ2GPI are well known to activate monocytes and endothelial cells via the intracellular NF-kB pathway with prothrombotic implications.By contrast,the interaction of anti-β2GPI/β2GPI complexes with platelets has not been extensively studied.The p38 mitogen-activated protein kinase(MAPK)pathway has been recognized to be an important intracellular signaling pathway in the coagulation cascade and an integral component of arterial and venous thrombosis.The present study reveals that levels of anti-β2GPI/β2GPI complexes in sera are positively associated with p38MAPK phosphorylation of platelets in thrombotic patients.Furthermore,SB203580 inhibits anti-β2GPI/β2GPI complex-induced platelet activation.Thrombus formation decreased in p38MAPK−/−mice after treatment with anti-β2GPI/β2GPI complexes.In conclusion,p38MAPK may be a treatment target for anti-β2GPI antibody-associated thrombotic events. | Wenjing Zhang Caijun Zha Xiumin Lu Ruichun Jia Fei Gao Qi Sun Meili Jin Yanhong Li | 2019 | Frontiers of Medicine2019，13，6： | 3 |
| 11 | Contrasting vegetation changes in dry and humid regions ofthe Tibetan Plateau over recent decades显示文摘An overall greening over the Tibetan Plateau(TP) in recent decades has been established through analyses of remotely sensed Normalized Difference Vegetation Index(NDVI), though the regional pattern of the changes and associated drivers remain to be explored. This study used a satellite Leaf Area Index(LAI) dataset(the GLASS LAI dataset) and examined vegetation changes in humid and arid regions of the TP during 1982–2012. Based on distributions of the major vegetation types, the TP was divided roughly into a humid southeastern region dominated by meadow and a dry northwestern region covered mainly by steppe. It was found that the dividing line between the two regions corresponded well with the lines of mean annual precipitation of 400 mm and the mean LAI of 0.3. LAI=0.3 was subsequently used as a threshold for investigating vegetation type changes at the interanual and decadal time scales: if LAI increased from less than 0.3 to greater than0.3 from one time period to the next, it was regarded as a change from steppe to meadow, and vice versa. The analysis shows that changes in vegetation types occurred primarily around the dividing line of the two regions, with clear growth(reduction) of the area covered by meadow(steppe), in consistency with the findings from using another independent satellite product. Surface air temperature and precipitation(diurnal temperature range) appeared to contribute positively(negatively) to this change though climate variables displayed varying correlation with LAI for different time periods and different regions. | RuiQing Li YanHong Gao DeLiang Chen YongXin Zhang SuoSuo Li | 2018 | Research in Cold and Arid Regions2018，10，6： | 3 |
| 12 | Effects of key growth conditions on endogenous hormone content in tillering stem bases,germination of lateral buds,and biomass allocation in Indocalamus decorus显示文摘Physiological responses and changes in growth of Indocalamus decorus Q.H.Dai under different ecological conditions are essential for further understanding growth regulation and adaptive mechanisms and establishing an evidence-based management system for optimal growth. In this study, the endogenous hormone content in tillering stem bases, germination of lateral buds, and biomass allocation of this bamboo species in different growth environments were investigated. Among the endogenous hormones in the basal stems of tillers, indole-3-pyruvic acid and zeatin riboside were highly correlated with lateral buds that germinated to form shoots, while gibberellic acid was highly correlated with lateral buds that germinated to form rhizomes. The best lateral bud germination characteristics were achieved with full sun, a density of six plantlets per pot, and watering every 6 days. I. decorus plantlets used different resource allocation strategies depending on treatment. Different ecological factors influenced endogenous hormones in the bamboo stem base,which affected lateral bud germination and biomass allocation. | Guibin Gao Hao Zhong Zhizhuang Wu Neng Li Zheke Zhong Yanhong Pan Liangru Wu | 2018 | Journal of Forestry Research2018，29，6： | 3 |

| 14 | DNA damage repair promotion in colonic epithelial cells by andrographolide downregulated cGAS-STING pathway activation and contributed to the relief of CPT-11-induced intestinal mucositis显示文摘Gastrointestinal mucositis is one of the most debilitating side effects of the chemotherapeutic agent irinotecan(CPT-11). Andrographolide, a natural bicyclic diterpenoid lactone, has been reported to possess anti-colitis activity. In this study, andrographolide treatment was found to significantly relieve CPT-11-induced colitis in tumor-bearing mice without decreasing the tumor suppression effect of CPT-11. CPT-11 causes DNA damage and the release of double-stranded DNA(ds DNA) from the intestine, leading to cyclic-GMP-AMP synthase(c GAS)-stimulator of interferon genes(STING)-mediated colitis, which was significantly decreased by andrographolide both in vivo and in vitro. Mechanistic studies revealed that andrographolide could promote homologous recombination(HR) repair and downregulate ds DNA-c GAS-STING signaling and contribute to the improvement of CPT-11-induced gastrointestinal mucositis. These results suggest that andrographolide may be a novel agent to relieve gastrointestinal mucositis caused by CPT-11. | Yuanyuan Wang Bin Wei Danping Wang Jingjing Wu Jianhua Gao Haiqing Zhong Yang Sun Qiang Xu Wen Liu Yanhong Gu Wenjie Guo | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 3 |
| 15 | Impacts of Topographic Complexity on Modeling Moisture Transport and Precipitation over the Tibetan Plateau in Summer显示文摘The non-hydrostatic global variable resolution model(MPAS-atmosphere)is used to conduct the simulations for the South Asian Summer monsoon season(June,July,and August)in 2015 with a refinement over the Tibetan Plateau(TP)at the convection-permitting scale(4 km).Two experiments with different topographical datasets,complex(4-km)and smooth(60-km)topography,are designed to investigate the impacts of topographical complexity on moisture transport and precipitation.Compared with the observations and reanalysis data,the simulation can successfully capture the general features of key meteorological fields over the TP despite slightly underestimating the inflow through the southern TP.The results indicate that the complex topography can decrease the inward and outward moisture transport,ultimately increasing the total net moisture transport into the TP by~11%.The impacts of complex topography on precipitation are negligible over the TP,but the spatial distributions of precipitation over the Himalayas are significantly modulated.With the inclusion of complex topography,the sharper southern slopes of the Himalayas shift the lifted airflow and hence precipitation northward compared to the smooth topography.In addition,more small-scale valleys are resolved by the inclusion of complex topography,which serve as channels for moisture transport across the Himalayas,further favoring a northward shift of precipitation.Overall,the difference between the two experiments with different topography datasets is mainly attributed to their differing representation of the degree of the southern slopes of the Himalayas and the extent to which the valleys are resolved. | Gudongze LI Haoming CHEN Mingyue XU Chun ZHAO Lei ZHONG Rui LI Yunfei FU Yanhong GAO | 2022 | Advances in Atmospheric Sciences2022，39，7： | 3 |
| 16 | Characteristics of soil water repellency after sand dune stabilization in the Tengger Desert显示文摘Soil water repellency (SWR) is one of the most important physical properties of soils found all over the world, and it may have significant effects on the eco-hydrological processes of land ecosystems. In this study, the Capillary Rise Method was used to measure the SWR in the artificial vegetation area in Shapotou, located in the southeast area of the Tengger Desert, Ningxia Province of western China. The variation of the soil water repellency among different minor topographies, different depths and different particle sizes was analyzed. The results of the study indicate that the SWR shows distinct changes with vegetation restoration, and it increases with an increase in the period of dune stabilization. In the same vegetation area, the SWR of soils in inter-dune depressions or windward slopes is slightly greater than that in crest or leeward slopes. The SWR of 0-3 cm topsoil is significantly greater than that in the 3-6 cm soil layer. The SWR decreases with an increase in grain size and the differences among the SWRs of different sieved soil fractions are found to be significant. There is also a significantly positive correlation between the SWR and the proportion of soils with grain sizes of 0-0.05, 0.05-0.01 and 0.01-0.15 mm, and a significantly negative correlation between the SWR and the propotion of soils with grain sizes exceeding 0.15 mm. The increase of SWR in revegetation areas may depend on the continuous depositing of atmospheric dust on the stabilized dune surface as well as the formation of biological soil crusts, especially on the formation of algal and lichen crusts. Enhanced SWR influences the effectiveness of water use of sand plants inhabiting the sand dunes. | HaoTian Yang LiChao Liu XinRong Li YongPing Wei YanHong Gao XiaoJun Li RongLiang Jia Lei Huang | 2012 | Research in Cold and Arid Regions2012，4，5： | 2 |

| 18 | Seasonal variation in soil microbial biomass carbon and nitrogen in an artificial sand-binding vegetation area in Shapotou, northern China显示文摘In this study,seasonal variation characteristics of surface soil microbial biomass carbon(MBC)and soil microbial biomass nitrogen(MBN)of an artificial vegetation area located in Shapotou for different time periods were studied using the chloroform fumigation method,and the results were compared with those of near-natural vegetation areas and mobile dunes.Results showed that the MBC and MBN levels in the 0–5 cm soil layer were higher in autumn than in summer and spring.As the prolongation of vegetation restoration raised the MBC and MBN levels in summer and autumn,no clear variation was found in spring.However,the MBC and MBN in 5–20 cm had no obvious seasonal variation.During summer and autumn,the variation trend of MBC and MBN in the vertical direction was shown to be0–5>5–10>10–20 cm in the vegetation area,while for mobile dunes,the MBC and MBN levels increased as the depth increased.The natural vegetation area was shown to possess the highest MBC and MBN levels,and yet mobile dunes have the lowest MBC and MBN levels.MBC and MBN levels in artificial sand-binding vegetation increased with the prolongation of vegetation restoration,indicating that the succession of sand-binding vegetation will result in the accumulation of soil carbon and nitrogen,as well as the restoration of soil fertility. | YuYan Zhou XuanMing Zhang XiaoHong Jia JinQin Ma YanHong Gao | 2013 | Research in Cold and Arid Regions2013，5，6： | 2 |
| 19 | Correlation of chloride diffusion coefficient and microstructure parameters in concrete: A comparative analysis using NMR,MIP, and X-CT显示文摘Permeability is a major indicator of concrete durability,and depends primarily on the microstructure characteristics of concrete,including its porosity and pore size distribution.In this study,a variety of concrete samples were prepared to investigate their microstructure characteristics via nuclear magnetic resonance(NMR),mercury intrusion porosimetry(MIP),and X-ray computed tomography(X-CT).Furthermore,the chloride diffusion coefficient of concrete was measured to explore its correlation with the microstructure of the concrete samples.Results show that the proportion of pores with diameters<1000 nm obtained by NMR exceeds that obtained by MIP,although the difference in the total porosity determined by both methods is minimal.X-CT measurements obtained a relatively small porosity;however,this likely reflcts the distribution of large pores more accurately.A strong correlation is observed between the chloride diffusion coefficient and the porosity or contributive porosity of pores with sizes<1000 nm.Moreover,microstructure parameters measured via NMR reveal a lower correlation coefficient R2 versus the chloride diffusion coefficient relative to the parameters determined via MIP,as NMR can measure non-connected as well as connected pores.In addition,when analyzing pores with sizes>50 um,X-CT obtains the maximal contributive porosity,followed by MIP and NMR. | Yurong ZHANG Shengxuan XU Yanhong GAO Jie GUO Yinghui CAO Junzhi ZHANG | 2020 | Frontiers of Structural and Civil Engineering2020，14，6： | 2 |
| 20 | Internal Loads and Bioavailability of Phosphorus and Nitrogen in Dianchi Lake,China显示文摘Sediments have a significant influence on the cycling of nutrient elements in lake environments. In order to assess the distribution characteristics and estimate the bioavailability of phosphorus and nitrogen in Dianchi Lake, organic and inorganic phosphorus and nitrogen forms were analysed. The 210 Pb radiometric dating method was employed to study temporal changes in the phosphorus and nitrogen pools in Dianchi Lake. The result show that the total phosphorus(TP) and total nitrogen(TN) were both at high concentrations, ranging from 697.5–3210.0 mg/kg and 1263.7–7155.2 mg/kg, respectively. Inorganic phosphorus(IP) and total organic nitrogen(TON) were the main constituents, at percentages of 59%–78% and 74%–95%, respectively, in the sediments. Spatially, there was a decreasing trend in phosphorus and nitrogen contents from the south and north to the lake centre, which is related to the distribution pattern of local economic production. The burial rates of the various phosphorus and nitrogen forms increased in same spatially and over time. Particularly in the past two decades, the burial rates doubled, with that TN reached to 1.287 mg/(cm^2·yr) in 2014. As the most reactive forms, nitrate nitrogen(NO_3-N) and ammonia nitrogen(NH_4-N) were buried more rapidly in the south region, implying that the potential for releasing sedimentary nitrogen increased from north to south. Based on their concentrations and burial rates, the internal loads of phosphorus and nitrogen were analysed for the last century. A TP pool of 71597.6 t and a TN pool of 81191.7 t were estimated for Dianchi Lake. Bioavailable phosphorus and nitrogen pools were also estimated at 44468.0 t and 5429.7 t, respectively, for the last century. | WU Yalin HUANG Tao HUANG Changchun SHEN Yinyin LUO Yang YANG Hao YU Yanhong LI Ruixiao GAO Yan ZHANG Mingli | 2018 | Chinese Geographical Science2018，28，5： | 2 |
