3Chemical characteristics of precipitation at Nanping Mangdang Mountain in eastern China during spring显示文摘To study the characteristics of precipitation in eastern China,an automatic sampler was used to collect rainwater samples from 19 precipitation events at Mangdang Mountain,Nanping City,Fujiang Province,in the spring of 2009.We used ion chromatography to analyze the ionic components and concentrations,and inductively coupled plasma mass spectrometry (ICP-MS) to analyze element compositions and contents.The results demonstrated remarkable acidic characteristics:in more than 80% of precipitation events the pH was less than 5.6,with an average of 4.81.Mass concentration results showed SO 4 2 was the main anionic component (36.2% of the total anion mass),while NH 4+ was the main cationic component (47.7% of the total cation mass) and main ion for acidity neutralization in the rainwater.Organic acid content accounted for 30.9% of total anion mass.The main trace metals were Ca,K,and Na.The SO 4 2/NO 3 ratio was 1.4,indicating that precipitation in this region was influenced by complex air pollution-the product of individual coal-burning combined with vehicle exhaust pollution.Correlation analysis of the chemical composition of the precipitation indicated that acidity in this region was determined by a combination of all acidic and neutralization ions rather than any single ion component.The results also showed that Na+ and Cl contributions were mainly by seawater;Mg 2+ by seawater and crustal materials;the NH 4+,K+,Ca 2+,NO 3 and SO 4 2 by anthropogenic sources;the trace metals were from the Earth's crust;and organic acids were potentially from combustion of biomass.Yanli Cheng Ying Liu Mingqun Huo Qian Sun Huixiang Wang Zhongming Chen Yuhua Bai 2011Journal of Environmental Sciences2011,23,8:8

5Downregulation of LINC01296 suppresses non-small-cell lung cancer via targeting miR-143-3p/ATG2B显示文摘The 5-year survival rate of lung cancer is one of the lowest among various malignant tumors.Long noncoding RNAs(lncRNAs),noncoding RNAs longer than 200 nucleotides,can function either as tumor suppressors or as oncogenes.The aim of this study is to investigate the function of lncRNA LINC01296 and its molecular mechanism in non-small-cell lung cancer(NSCLC).According to the Gene Expression Omnibus database,10 differentially expressed lncRNAs in NSCLC cells and patient tissues are upregulated.LINC01296 is the one with the most significant overexpression.Knockdown of LINC01296 inhibits the growth and migration,arrests the cell cycle,and promotes the apoptosis of NSCLC cells.Knocking down LINC01296 in vivo suppresses tumor growth and metastasis.LINC01296 also acts as the sponge of miR-143-3p.Lowering the expression of LINC01296 leads to decreased expression of autophagy-related 2B,ATG2B,a target gene of miR-143-3p.Moreover,downregulation of LINC01296 promotes paclitaxel sensitivity in NSCLC.These results demonstrated that the LINC01296/miR-143-3p/ATG2B axis is crucial in promoting the development of NSCLC and paclitaxel resistance.Our study may provide new ideas for the further research of clinical chemotherapy of NSCLC in the near future.Yanli Li Hui Zhang Jing Guo Wanqiu Li Xianyi Wang Caiyan Zhang Qiangling Sun Zhongliang Ma 2021Acta Biochimica et Biophysica Sinica2021,53,12:8
6Large-area straight,regular periodic surface structures produced on fused silica by the interference of two femtosecond laser beams through cylindrical lens显示文摘Inhomogeneity and low efficiency are two important factors that limit the application of laser-induced periodic surface structures(LIPSSs),especially on glass surfaces.In this study,two-beam interference(TBI)of femtosecond lasers was used to produce large-area straight LIPSSs on fused silica using cylindrical lenses.Compared with those produced us-ing a single circular or cylindrical lens,the LIPSSs produced by TBI are much straighter and more regular.Depending on the laser fluence and scanning velocity,LIPSSs with grating-like or spaced LIPSSs are produced on the fused silica sur-face.Their structural colors are blue,green,and red,and only green and red,respectively.Grating-like LIPSS patterns oriented in different directions are obtained and exhibit bright and vivid colors,indicating potential applications in surface coloring and anti-counterfeiting logos.Long Chen Kaiqiang Cao Yanli Li Jukun Liu Shian Zhang Donghai Feng Zhenrong Sun Tianqing Jia 2021Opto-Electronic Advances2021,4,12:7
7Enhanced Vitamin C Production Mediated by an ABA-Induced PTP-like Nucleotidase Improves Plant Drought Tolerance in Arabidopsis and Maize显示文摘Abscisic acid(ABA)is a key phytohormone that mediates environmental stress responses.Vitamin C,or L-ascorbic acid(AsA),is the most abundant antioxidant protecting against stress damage in plants.How the ABA and AsA signaling pathways interact in stress responses remains elusive.In this study,we characterized the role of a previously unidentified gene,PTPN(PTP-like Nucleotidase)in plant drought tolerance.In Arabidopsis,(AtPTPN was expressed in multiple tissues and upregulated by ABA and drought treatments.Loss-of-function mutants oiAtPTPN were hyposensitive to ABA but hypersensitive to drought stresses,whereas plants with enhanced expression AtPTPN showed opposite phenotypes to.Overexpression of maize PTPN(ZmPTPN)promoted,while knockdown oiZmPTPN inhibited plant drought tolerance,indicating conserved and positive roles of PTPN in plant drought tolerance.We found that both AtPTPN and ZmPTPN release Pi by hydrolyzing GDP/GMP/dGMP/IMP/dIMP,and that AtPTPN positively regulated AsA production via endogenous Pi content control.Consistently,overexpression of VTC2,the rate-limiting synthetic enzyme in AsA biosynthesis,promoted AsA production and plant drought tolerance,and these effects were largely dependent on AtPTPN activity.Furthermore,we demonstrated that the heat shock transcription factor HSFA6a directly binds the AtPTPN promoter and activates AtPTPN expression.Genetic analyses showed that AtPTPN is required for HSFA6a to regulate ABA and drought responses.Taken together,our data indicate that PTPN-mediated crosstalk between the ABA signaling and AsA biosynthesis pathways positively controls plant drought tolerance.Hui Zhang Yanli Xiang Neng He Xiangguo Liu Hongbo Liu Liping Fang Fei Zhang Xiaopeng Sun Delin Zhang Xingwang Li William Terzaghi Jianbing Yan Mingqiu Dai 2020Molecular Plant2020,13,5:7

9Surface quality of cold rolling aluminum strips under lubrication condition显示文摘The effects of oil film on the rolled surface,including surface roughness and topography,were investigated during cold rolling of aluminum strips.Various mineral oils with viscosities from 0.10 to 1.6 Pa.s were used to obtain different oil film thick- nesses.Results from experiment and calculation show that the thicker oil film protects the initial roughening surface so that it leads to an increase in roughness of the rolled surface,in particular when the surface roughness has the character of direction.The rolled surface roughness was determined byλ,which is the ratio of oil film thickness to the combined surface roughness.Whenλ>3,the rolled surface roughness increases rapidly with the increase in oil viscosity,whereas the surface roughening has already occurred whenλ<3,but the increase of the rolled surface roughness with increasing viscosity is not distinct.Jianlin Sun Wang Lu Yanli Ma Qingbing Shi Aihua Zhang Jian Li 2008Journal of University of Science and Technology Beijing2008,15,3:6
10Studies on Factors Influencing Hydrodynamic Characteristics of Plates Used in Artificial Reefs显示文摘As a simplified model of artificial reefs, a series of plate models punched with square or circular openings are designed to investigate the effects of openings on the hydrodynamic characteristics of artificial reefs. The models are grouped by various opening numbers and opening-area ratios. They are physically tested in a water flume or used in the numerical simulation to obtain the drag force in the uniform flow with different speeds. The simulation results are found in good agreement with the experimental measurements. By the non-dimensional analysis, the drag coefficient specified to each model is achieved and the effects of openings are examined. It is found that the key factor affecting the drag coefficient is the open-area ratio. Generally, the drag coefficient is a linear function of the open area ratio with a minus slope. The empirical formulae for the square and circular openings respectively are deduced by means of the multiple regression analysis based on the measured and numerical data. They will be good references for the design of new artificial reefs. As a result of numerical simulation, the vorticity contours and pressure distribution are also presented in this work to better understand the hydrodynamic characteristics of different models.TANG Yanli YANG Wenzhao SUN Liyuan ZHAO Fenfang LONG Xiangyu WANG Gang 2019Journal of Ocean University of China2019,18,1:6
11Dissecting human embryonic skeletal stem cell ontogeny by single-cell transcriptomic and functional analyses显示文摘Human skeletal stem cells(SSCs)have been discovered in fetal and adult long bones.However,the spatiotemporal ontogeny of human embryonic SSCs during early skeletogenesis remains elusive.Here we map the transcriptional landscape of human limb buds and embryonic long bones at single-cell resolution to address this fundamental question.We found remarkable heterogeneity within human limb bud mesenchyme and epithelium,and aligned them along the proximal-distal and anterior-posterior axes using known marker genes.Osteo-chondrogenic progenitors first appeared in the core limb bud mesenchyme,which give rise to multiple populations of stem/progenitor cells in embryonic long bones undergoing endochondral ossification.Importantly,a perichondrial embryonic skeletal stem/progenitor cell(eSSPC)subset was identified,which could self-renew and generate the osteochondral lineage cells,but not adipocytes or hematopoietic stroma.eSSPCs are marked by the adhesion molecule CADM1 and highly enriched with FOXP1/2 transcriptional network.Interestingly,neural crest-derived cells with similar phenotypic markers and transcriptional networks were also found in the sagittal suture of human embryonic calvaria.Taken together,this study revealed the cellular heterogeneity and lineage hierarchy during human embryonic skeletogenesis,and identified distinct skeletal stem/progenitor cells that orchestrate endochondral and intramembranous ossification.Jian He Jing Yan Jianfang Wang Liangyu Zhao Qian Xin Yang Zeng Yuxi Sun Han Zhang Zhijie Bai Zongcheng Li Yanli Ni Yandong Gong Yunqiao Li Han He Zhilei Bian Yu Lan Chunyu Ma Lihong Bian Heng Zhu Bing Liu Rui Yue 2021Cell Research2021,31,7:5
12Effect of Preparation Process on Compressive Strength and Hydrogenation Performance of Raney-Ni/Al2O3 Catalyst显示文摘In this study, Raney-Ni/Al_2O_3 catalysts were prepared from precursors which were calcined in different atmosphere(argon and air) and leached for different time. XRD, SEM, H_2-TPR and BET techniques were introduced to characterize the catalysts, and hydrogenation of unsaturated hydrocarbons, including vinyltoluene, dicyclopentadiene and indene, was used as probe reaction to evaluate the catalytic hydrogenation performance of the catalysts. The results demonstrated that the calcination atmosphere had noticeable effects on the compressive strength and hydrogenation performance of Raney-Ni/Al_2O_3. The catalyst calcined in argon exhibited better compressive strength and catalytic performance than the one calcined in air. The compressive strength and activity stability of catalyst were also determined by the leaching time. A too longer leaching time was not conducive to improving the compressive strength and catalytic performance of catalysts. When the precursor calcined in argon was treated in a 15%(by wt.) sodium hydroxide solution at 343 K for 5 h, a catalyst with higher compressive strength(at 26.10 N/mm) was obtained and the conversion of vinyltoluene, dicyclopentadiene(DCPD), and indene could amount to more than 87.5%, 99% and even 100%, respectively, under the reaction conditions covering a temperature of 493 K, a hydrogen pressure of 2.0 MPa, a LSHV of 3.0 h^(-1), and a hydrogen/oil ratio of 200:1.Luo Guohua Wang Yanli Sun Daming Xu Xin Jin Haibo 2017China Petroleum Processing & Petrochemical Technology2017,19,2:5
13A prediction method of natural gas hydrate formation in deepwater gas well and its application显示文摘To prevent the deposition of natural gas hydrate in deepwater gas well,the hydrate formation area in wellbore must be predicted.Herein,by comparing four prediction methods of temperature in pipe with field data and comparing five prediction methods of hydrate formation with experiment data,a method based on OLGA&PVTsim for predicting the hydrate formation area in wellbore was proposed.Meanwhile,The hydrate formation under the conditions of steady production,throttling and shut-in was predicted by using this method based on a well data in the South China Sea.The results indicate that the hydrate formation area decreases with the increase of gas production,inhibitor concentrations and the thickness of insulation materials and increases with the increase of thermal conductivity of insulation materials and shutdown time.Throttling effect causes a plunge in temperature and pressure in wellbore,thus leading to an increase of hydrate formation area.Yanli Guo Baojiang Sun Keke Zhao Hongkun Zhang 2016Petroleum2016,2,3:5
14Significant Effects of Fishing Gear Selectivity on Fish Life History显示文摘Over the past few decades, extreme changes have occurred in the characters of exploited fish populations. The majority of these changes have affected the growth traits of fish life history, which include a smaller size-at-age, an earlier age-at-maturation and among others. Currently, the causes of these life history traits changes still require systematic analyses and empirical studies. The explanations that have been cited are merely expressed in terms of fish phenotypic adaptation. It has been claimed that the original traits of fish can be recovered once the intensity of exploitation of the fish is controlled. Sustained environmental and fishing pressure will change the life history traits of most fish species, so the fish individual's traits are still in small size-at-age and at earlier age-at-maturation in exploited fish populations. In this paper, we expressed our view of points that fishing gear has imposed selectivity on fish populations and individuals as various other environmental factors have done and such changes are unrecoverable. According to the existing tend of exploited fish individual's life history traits, we suggested further researches in this field and provided better methods of fishery management and thereby fishery resources protection than those available early.LIANG Zhenlin SUN Peng YAN Wei HUANG Liuyi TANG Yanli 2014Journal of Ocean University of China2014,13,3:4
15The Detecting System of Image Forgeries with Noise Features and EXIF Information显示文摘Recently, the digital image blind forensics technology has received an increasing attention in academic community. This paper aims at developing a new identification approach based on the statistical noise and exchangeable image file format(EXIF) information of image for images authentication. In particular, the authors can identify whether the current image has been modified or not by utilizing the relevance between noise and EXIF parameters and comparing the real values with the estimated values of the EXIF parameters. Experimental results validate the proposed method. That is, the detecting system can identify the doctored image effectively.SUN Xiaoting LI Yezhou NIU Shaozhang HUANG Yanli 2015Journal of Systems Engineering and Electronics2015,26,5:4
16Pseudocapacitance boosted N-doped carbon coated Fe7S8 nanoaggregates as promising anode materials for lithium and sodium storage显示文摘Herein,the core-shell structured N-doped carbon coated Fe7S8 nano-aggregates(Fe7S8@NC)were controllably prepared via a simple three-step synthesis strategy.The appropriate thickness of N-doped carbon layer outside Fe7S8 nano-aggregates can not only inhibit the particle pulverization induced by the big volume changes of Fe7S8,but can increase the electron transfer efficiency.The hierarchical Fe7S8 nano-aggregates composed of some primary nanoparticles can accelerate the lithium or sodium diffusion kinetics.As anode materials for Li-ion batteries(LIBs),the well-designed Fe7S8@NC nanocomposites exhibit outstanding lithium storage performance,which is better than that of pure Fe7S8,Fe3O4@NC and Fe7S8@C.Among these nanocomposites,the N-doped carbon coated Fe7S8 with carbon content of 26.87 wt.%shows a high reversible specific capacity of 833 mAh·g^−1 after 1,000 cycles at a high current density of 2 A·g^−1.The above electrode also shows excellent high rate sodium storage performance.The experimental and theoretical analyses indicate that the outstanding electrochemical performance could be attributed to the synergistic effect of hierarchical Fe7S8 nanostructure and conductive N-doped carbon layer.The quantitative kinetic analysis indicates that the charge storage of Fe7S8@NC electrode is a combination of diffusion-controlled battery behavior and surface-induced capacitance behavior.Yanli Zhou Ming Zhang Qi Wang Jian Yang Xingyun Luo Yanlu Li Rong Du Xinsheng Yan Xueqin Sun Caifu Dong Xiaoyu Zhang Fuyi Jiang 2020Nano Research2020,13,3:4
17Busuishengxue ranules mediate their effects upon non-severe aplastic anemia via mitogen-activated protein kinase/extracellular signal-regulated kinase pathway显示文摘OBJECTIVE:To observe the clinical efficacy of Busuishengxue granules on non-severe aplastic anemia(NSAA)and investigate its effect on the mitogen-activated protein kinase/extracellular signal-regulated kinase(MAPK/ERK)pathway.METHODS:Sixty NSAA patients were divided equally into two groups.Subjects in the experimental group were treated with Busuishengxue granules,and the control group with Zaizaoshengxue tablets.The treatment course was 6 months and cu-rative efficacy was compared between the two groups as well as with 10 healthy individuals.Flow cytometry(FCM)was used to detect the intracellular concentration of Ca2+([Ca2+]i).Western blotting was employed to detect the expression of enzymes in the MAPK/ERK pathway.RESULTS:The efficacy of Busuishengxue granules was significantly better than that of Zaizaoshengxue tablets(P<0.05).Before treatment,expression of JNK,phospho-ERK 1/2 and p-JNK was higher,and[Ca2+]i higher,than that of the control group(P<0.05).After treatment with Busuishengxue granules,expression of all enzymes related to signal transduction pathways in the blood cells of NSSA patients were altered to different degrees.CONCLUSION:Busuishengxue granules had a better effect with regard to improving symptom scores,increasing the number of blood leukocytes,and increasing hemoglobin levels than Zaizaoshengxue tablets,and they differed slightly in terms of increasing the number of platelets.Jinhuan Wang Feng Sun Weizheng Sun Yanli Yong Haitao Shi Sijia Liu Limei Liu 2014Journal of Traditional Chinese Medicine2014,34,1:3
18A Novel Strategy to Fabricate Core-Sheath Structure Piezoelectric Yarns for Wearable Energy Harvesters显示文摘Wearable and portable electronic devices based on textile structure have been widely used owing to their wearability and comfortableness.However,yarn fineness and the comfort of the fabric cannot satisfy the requirements of smart wearable devices.This work presents a novel strategy to prepare highly integrated PVDF/conductive nylon core-sheath structure piezoelectric yarns for wearable which is fabricated by combining electrospinning strategy with 2D braiding technology.The fineness of single yarns as well as strength are both improved significantly compared to previous works.The piezoelectric outputs of the yarn are still stable after 800 s fatigue test at a frequency of 4 Hz,and the cycle stability can maintain more than 3200 cycles.Furthermore,the piezoelectric yarns are further woven into piezoelectric plain fabric.According to the electrical performance,the length of the piezoelectric yarn and the thickness of the piezoelectric layer would both affect the output electrical performance.The yarn of the 10 cm in length and 600μm in fineness can produce an output voltage of 120 mV.Meanwhile,Both the piezoelectric yarn and the fabric could generate piezoelectric output signals through human movement,such as bending,walking.Therefore,the electrical and mechanical performance of the piezoelectric yarns prepared in our work could be improved significantly,and the comfortableness and durability performance of the piezoelectric fabric can satisfy most wearing requirements,which would provide some help in the field of piezoelectric wearable devices based on yarns and fabrics.Lili Xue Wei Fan Yang Yu Kai Dong Chengkun Liu Yanli Sun Cong Zhang Weichun Chen Ruixin Lei Kai Rong Qi Wang 2021Advanced Fiber Materials2021,3,4:3

20BTEX anomalies used as indicators of submarine oil and gas reservoirs显示文摘It is a conventional method for petroleum prospecting to generally use paraffin hydrocarbon as basic indexes of oil and gas. This conventional geochemical technology, however, shows some limits in the prospecting as paraffin is vulnerable to influences from human and biologic activities. Consequently, BTEX (short for benzene, toluene, ethyl benzene and xylem, which are direct biomarkers) among aromatic hydrocarbon series has been taken into account for the oil and gas prediction. Domestic and foreign study results demonstrate that BTEX is hardly disturbed and can well indicate oil and gas reservoirs. Based on measured data from a South China Sea area, the present authors have used self-developed visual assessment software for petroleum prospecting has been used to process data, strip background anomalies, and outline significant BTEX anomalies. By comparison with stratigraphic profiles of the target area, it is confirmed that BTEX is a good indication of marine oil and gas during the petroleum prospecting.ZHANG Yong MENG Xiangjun SUN Ping CHEN Yanli QU Peng 2009Acta Oceanologica Sinica2009,28,4:3
