| 1 | Relation between electricity structure of the crust and deformation of crustal blocks on the northeastern margin of Qinghai-Tibet Plateau显示文摘Study on the electricity structure along a magnetotelluric (MT) sounding profile on the northeastern margin of Qinghai-Tibet Plateau indicates that four crustal blocks can be de-termined from southwest to northeast, namely Bayan Har block (BH), Qin-Qi block (QQ), Hai-yuan block (HY) or the North-South seismotectonic belt and Ordos block (OD). The BH, QQ and OD blocks display a similar electricity structure of the crust. The upper crust represents a high- resistivity layer and the upper part of lower crust represents a low-resistivity layer with the resis-tivity increasing gradually with depth from the lower part of lower crust to the upper mantle. The electricity structure of the crust in these three blocks is similar to that in the complete blocks on the southern and eastern margins of the Qinghai-Tibet Plateau and belongs to normal electricity layering of the crust in slightly deformed or complete intracontinental blocks. The crust in HY block as a boundary zone has been significantly deformed, hence its electricity layering was de-stroyed and the structure was complex and the block became a recent tectonically active and great seismo-active region. The contact belts between the blocks on the northeastern margin of Qinghai-Tibet Plateau exhibit both upthrusting outward and strike-slip movement different from those on the southern and eastern margins of the plateau. The genesis of the low-resistivity layer in the crust is analyzed and the thickness of the lithosphere is estimated in the paper. | ZHAO Guoze TANG Ji ZHAN Yan CHEN Xiaobin ZHUO Xianjun WANG Jijun XUAN Fei DENG Qianhui ZHAO Junmeng | 2005 | Science China Earth Sciences2005,48,10: | 20 |
| 2 | Research progress on the relationship between intestinal microecology and intestinal bowel disease显示文摘Intestinal microecology is the main component of human microecology.Intestinal microecology consists of intestinal microbiota,intestinal epithelial cells,and intestinal mucosal immune system.These components are interdependent and establish a complex interaction network that restricts each other.According to the impact on the human body,there are three categories of symbiotic bacteria,opportunistic pathogens,and pathogenic bacteria.The intestinal microecology participates in digestion and absorption,and material metabolism,and inhibits the growth of pathogenic microorganisms.It also acts as the body’s natural immune barrier,regulates the innate immunity of the intestine,controls the mucosal barrier function,and also participates in the intestinal epithelial cells’physiological activities such as hyperplasia or apoptosis.When the steady-state balance of the intestinal microecology is disturbed,the existing core intestinal microbiota network changes and leads to obesity,diabetes,and many other diseases,especially irritable bowel syndrome,inflammatory bowel disease(IBD),and colorectal malignancy.Intestinal diseases,including tumors,are particularly closely related to intestinal microecology.This article systematically discusses the research progress on the relationship between IBD and intestinal microecology from the pathogenesis,treatment methods of IBD,and the changes in intestinal microbiota. | Qianhui Fu Tianyuan Song Xiaoqin Ma Jian Cui | 2022 | Animal Models and Experimental Medicine2022,5,4: | 9 |

| 4 | Latent fingerprint enhancement on conductive substrates using electrodeposition of copper显示文摘We presented a novel method for the development of a latent fingerprint by selective electrodeposition of a copper thin film from sulfate solution onto the conductive substrate between fingerprint ridges to generate a negative image of the fingerprint deposit. After optimizing the parameters(deposition time, deposition potential, and copper concentration), the preferential electrodeposition of copper films allowed latent fingerprints on six kinds of conductive surfaces(indium/tin oxide-coated glass, silver sheet, platinum sheet, gold sheet, copper sheet, and a stainless steel coin) to be successfully developed with high resolution. In addition, this technique could also be exploited to visualize latent fingerprints on rough and dirty surfaces. The quality of the developed fingerprints was estimated visually and the morphology of the copper film was characterized by field emission scanning electron microscopy. | Meiqin Zhang Xi Yu Gang Qin Yu Zhu Meiling Wang Qianhui Wei Yang Zhang Xueji Zhang | 2015 | Science China Chemistry2015,58,7: | 5 |
| 5 | Effects of Continuous Cropping of Panax notoginseng on the Properties of Rhizosphere Soil显示文摘[Objective] This experiment aimed to investigate the effects of continuous cropping of Panax notoginseng on the properties of rhizosphere soil. [Method] A total of 12 rhizospheres oil samples were collected in the fields continuously cropped with P. notoginseng for different years and the soil properties including pH value, contents of available N, available K, available P,total N, total K, total P and organic matter were determined. [Result] With the increase in the number of years of continuous cropping, seven soli indices: soil pH value, organic matter content, total N, total P, total K, available P and available K gradually increased, while available N showed a gradual downward trend. The contents of organic matter content, total N, total P, total K,available P, available K and available N after three years of continuous cropping were increased by 74.93%, 65.85%, 123.82%,18.78%, 341.67%, 120.16% and-32.16%, respectively, indicating that continuous cropping of P. notoginseng resulted in nutrient enrichment in rhizosphere soils. The pH value and available N in IBC(soil inside the border check) and UBC(soil under the border check) were higher than that in BBC(soil beside the border check), suggesting that the soil was gradually alkalized due to the continuous cropping of P. notoginseng. [Conclusion] These results suggest that pH change and nutrient imbalance may be the obstacles to the continuous cropping of P. notoginseng. | Kaiming LI Meixiang LIU Qianhui SUN Zilong ZHANG | 2017 | Agricultural Science & Technology2017,18,4: | 4 |
| 6 | Clinical Analysis of Early Noninvasive Mechanical Ventilation in the Treatment of Acute Left Heart Failure Complicated with Respiratory Failure显示文摘Objective To evaluate the efficacy of early and non-early non-invasive mechanical ventilation(NIV) for acute left heart failure and respiratory failure. Methods 29 cases of patients with acute left heart failure and respiratory failure treated by NIV were selected from our department from August 2016 to March 2019. According to the time of initiation of noninvasive mechanical ventilation, the patients were divided into the early treatment group(group A, treatment with NIV immediately after admission, n=15) and the non-early treatment group(group B, treatment with NIV for 2 h after admission, n=14), the improvement time, mechanical ventilation time, effective rate, intubation rate and fatality rate were compared between the two groups. Results The improvement time of patients in group A was(4.8±2.5) hours, the time of mechanical ventilation was(9.6±3.2) hours, the improvement time of group B was(6.8±2.6) hours, and the time of mechanical ventilation(12.8±4.4) hours. There were significant differences between the two groups(P<0.05). In group A, 13 patients were cured, 2 patients were intubated, 1 patient died, 10 patients in group B were cured, 4 patients were intubated, and 2 patients died. The difference in cure rate, intubation rate and mortality was statistically significant(P<0.05). Conclusion The treatment of acute left heart failure and respiratory failure is effective, and early application can improve the cure rate, reduce intubation and mortality. | Ting SUN Tianfu GONG Qianhui SUN Jian ZHANG Jiaming CAO | 2019 | 国际感染病学(电子版)2019,8,2: | 4 |
| 7 | Effect of different twirling and rotating acupuncture manipulation techniques on the blood flow perfusion at acupoints显示文摘OBJECTIVE: To analyze the effect of different twirling and rotating acupuncture manipulation techniques on the blood flow perfusion at acupoints to provide a reference for the study of acupoint specificity and the quantification and effectiveness of acupuncture methods. METHODS: Twenty healthy male or female college students each received four different acupuncture manipulation techniques, including simple acupuncture, uniform reinforcing-reducing needling, twirling reinforcing needling, and twisting reducing needling. The self-control method was applied. Acupuncture was performed by an acupuncture manipulation simulator at Neiguan (PC 6) and Zusanli (ST 36). The process of twirling and rotating was divided into seven timepoints. The PeriCam Perfusion Speckle Imager (PSI) System was used to collect the blood flow perfusion data at each acupoint. The specificity of twirling and rotating acupuncture manipulation was analyzed based on changes in the curve, video, and numerical blood flow perfusion data at each timepoint. RESULTS: There were two peaks in the blood flow perfusion curve of twirling and rotating acupuncture manipulation;one appeared after 3 min of needle retention, and the other appeared 3 min after needle removal. The blood flow perfusion parameters showed that the greatest differences between the four manipulation techniques occurred after 5 and 10 min of needle retention. The specificity of various manipulation techniques was most obvious at these two timepoints. There were significant differences between the four manipulation groups in the blood flow perfusion and the relative change rates of blood flow perfusion at each timepoint. CONCLUSION: Laser speckle imaging enables the real-time, non-invasive, rapid, and accurate collection of blood flow perfusion data during acupuncture. This imaging technique enables the easy attainment of various parameters such as visual images, two-dimensional curves, and data tables. At various timepoints, the four groups significantly differed regarding changes in blood flow perfusion and relative change rates of blood flow perfusion, which facilitated the differentiation of the four acupuncture manipulation methods. Based on this, further analysis could be conducted to study spatial distribution characteristics such as the influence area and flare area. The frequency domain analysis of acupuncture manipulation curves is important in the study of the dose-effect relationship and specificity of acupuncture manipulation. | Xu Gang Xi Qianhui Tang Wenchao Liu Tangyi Gao Ming Li Shaoxiong Wen Junling Yang Huayuan | 2019 | Journal of Traditional Chinese Medicine2019,39,5: | 3 |
| 8 | A Multi–fluid Constrain for the Forming of Potash Deposits in the Savannakhet Basin: Geochemical Evidence from Halite显示文摘The Khorat Plateau on the Indochina Terrane is known to have formed during the closure of the Tethys Ocean, although the origin of its potash mineral deposits is a topic of current debate. Data from a borehole on Savannakhet Basin is used in this study to re-define the evaporation processes of the study area. Geochemical analyses of halite from various borehole-derived evaporite strata have elucidated the fluid sources from which these ores formed. Measured δ11 B indicated that ore deposits formed primarily due to evaporation of seawater, although non-marine fluids affected the later stages of the evaporation process. Fluctuations in B and Br concentrations in carnallite-and sylvite-rich strata indicate the influence of fresh water. Boron concentration in carnallite unit indicated the influence of hydrothermal fluids. From the relative timings of these various fluid influxes, the evolution of these evaporates can be divided into four stages:(1) an initial marine evaporation at the beginning of the deposit's formation, where seawater(and minor fresh water) trapped on the uplifted Khorat Plateau produced sediments and salts with Br contents lower than those of normal marine-derived evaporites;(2) a transgression stage, where seawater recharged the basin;(3) a hydrothermal infiltration stage, which was coeval with the late Yanshan movement; and(4) a stage of fresh water supply, as recorded by fluctuations in B and Br contents, inferring intermittent fresh water influx into the basin. Thus, although evaporites on the Savannakhet Basin primarily formed via marine evaporation, they were also influenced to a significant degree by the addition of non–marine fresh water and hydrothermal fluids. | REN Qianhui DU Yongsheng GAO Donglin LI Binkai ZHANG Xiying LIU Xiuting YUAN Xiaolong | 2018 | Acta Geologica Sinica(English Edition)2018,92,2: | 3 |
| 9 | Porous nitrogen-enriched hollow carbon nanofibers as freestanding electrode for enhanced lithium storage显示文摘Onedimensional porous carbons bearing high surface areas and sufficient heteroatom doped functionalities are essential for advanced electrochemical energy storage devices,especially for developing freestanding film electrodes.Here we develop a porous,nitrogenenriched,freestanding hollow carbon nanofiber(PNFHCF)electrode material via filtration of polypyrrole(PPy)hollow nanofibers formed by in situ selfdegraded templateassisted strategy,followed by NH3assisted carbonization.The PNFHCF retains the freestanding film morphology that is composed of threedimensional networks from the entanglement of 1D nanofiber and delivers 3.7fold increase in specific surface area(592 m^(2)g^(-1))compared to the carbon without NH_(3)treatment(FHCF).In spite of the enhanced specific surface area,PNFHCF still exhibits comparable high content of surface N functionalities(8.8%,atom fraction)to FHCF.Such developed hierarchical porous structure without sacrificing N doping functionalities together enables the achievement of high capacity,highrate property and good cycling stability when applied as selfsupporting anode in lithiumion batteries,superior to those of FHCF without NH3 treatment. | Xiaosa Xu Yuqian Qiu Jianping Wu Baichuan Ding Qianhui Liu Guangshen Jiang Qiongqiong Lu Jiangan Wang Fei Xu Hongqiang Wang | 2021 | Chinese Journal of Chemical Engineering2021,34,4: | 3 |
| 10 | Research Progress on Estimation of the Atmospheric Boundary Layer Height显示文摘Atmospheric boundary layer height(ABLH)is an important parameter used to depict characteristics of the planetary boundary layer(PBL)in the lower troposphere.The ABLH is strongly associated with the vertical distributions of heat,mass,and energy in the PBL,and it is a key quantity in numerical simulation of the PBL and plays an essential role in atmospheric environmental assessment.In this paper,various definitions and methods for deriving and estimating the ABLH are summarized,from the perspectives of turbulent motion,PBL dynamics and thermodynamics,and distributions of various substances in the PBL.Different methods for determining the ABLH by means of direct observation and remote sensing retrieval are reviewed,and comparisons of the advantages and disadvantages of these methods are presented.The paper also summarizes the ABLH parameterization schemes,discusses current problems in the estimation of ABLH,and finally points out the directions for possible future breakthroughs in the ABLHrelated research and application. | Hongsheng ZHANG Xiaoye ZHANG Qianhui LI Xuhui CAI Shaojia FAN Yu SONG Fei HU Huizheng CHE Jiannong QUAN Ling KANG Tong ZHU | 2020 | Journal of Meteorological Research2020,34,3: | 3 |

| 14 | Geochemistry and Zircon U-Pb Geochronology of Early Paleozoic S-type Granites in the Eastern Qilian Block,Northwest China显示文摘The Qilian Block(QB)is a Precambrian micro-continent located in the northeastern Qinghai–Tibet Plateau.Prevalent Lower Paleozoic granitic magmatic rocks crop out in the QB.A new integrated study of zircon U-Pb ages and systematic whole-rock geochemical data for the Xindian,Dongjiazhuang and Xiaogaoling granites in the eastern segment of the QB constrains their emplacement ages,petrogenesis,and regional evolutionary history.U-Pb dating reveals that the Xindian granite was emplaced 454 Ma,and both the Dongjiazhuang and Xiaogaoling granites were emplaced ca.440 Ma.Geochemical study shows that all granites belong to the high-K calc-alkaline to shoshonitic series and are S-type granites formed by partial melting of continental crust,mainly metagraywacke.We infer that these ca.454–445 Ma granites formed in a syn-collisional setting during the continental collisional between the Qaidam and Qilian blocks. | LIU Xiuting LI Binkai HAN Jilong REN Erfeng GAO Donglin DU Yongsheng REN Qianhui ZHANG Yan | 2021 | Acta Geologica Sinica(English Edition)2021,95,2: | 1 |
| 15 | Maternal heterozygous mutation in CHEK1 leads to mitotic arrest in human zygotes显示文摘Dear Editor,The first mitotic division in zygotes is crucial for the beginning of the life cycle for the human.After fertilization,zygotes reactivate cell cycle,both paternal and maternal genomes replicate and reprogram to become totipotent.In the meantime,the male and female pronucleus move to the center of the zygote and merge.Then zygotes enter the metaphase,and sister chromatids separate into two daughter cells(Eckersley-Maslin et al.,2018;Reichmann et al.,2018).This is a sensitive time window and many perturbances may cause the first mitosis to fail. | Beili Chen Jianying Guo Ting Wang Qianhui Lee Jia Ming Fangfang Ding Haitao Li Zhiguo Zhang Lin Li Yunxia Cao Jie Na | 2022 | Protein & Cell2022,13,2: | 1 |

| 17 | Impact of the amount of PEG on prodrug nanoassemblies for efficient cancer therapy显示文摘PEGylation has been widely used to improve the pharmacokinetic properties of prodrug self-assembled nanoparticles(prodrug-SANPs).However,the impacts of the amount of PEG on the self-assemble stability,cellular uptake,pharmacokinetics,and antitumor efficacy of prodrug-SANPs are still unknown.Herein,selenoether bond bridged docetaxel dimeric prodrug was synthesized as the model prodrug.Five prodrug-SANPs were designed by using different mass ratios of prodrugs to PEG(W_(prodrug)/W_(DSPE-mPEG2000)=10:0,9:1,8:2,7:3 and 6:4),and defined as Pure drug NPs,9:1NPs,8:2NPs,7:3 NPs and 6:4 NPs,respectively.Interestingly,8:2 NPs formed the most compact nanostructure,thus improving the self-assemble stability and pharmacokinetics behavior.In addition,the difference of these prodrug-SANPs in cellular uptake was investigated,and the influence of PEG on cytotoxicity and antitumor efficacy was also clarified in details.The 8:2 NPs exhibited much better antitumor efficacy than other prodrug-SANPs and even commercial product.Our findings demonstrated the pivotal role of the amount of PEG on prodrug-SANPs. | Yaqiao Li Lingxiao Li Qianhui Jin Tian Liu Jin Sun Yongjun Wang Zhijun Yang Zhonggui He Bingjun Sun | 2022 | Asian Journal of Pharmaceutical Sciences2022,17,2: | 1 |
| 18 | Elucidating the role of SlXTH5 in tomato fruit softening显示文摘Fruit softening in tomato(Solanum lycopersicum)is closely associated with cell wall disassembly,which is brought about through the action of a range of cell wall structure-related enzymes and other proteins such as expansins.Xyloglucan endotransglucosylase/hydrolase(XTH)(EC 2.4.1.207 and/or EC 3.2.1.151)has been proposed to be key player involved in xyloglucan metabolism.SlXTH5 showed the highest expression level among all SlXTHs during tomato ripening.In this study,the role of SlXTH5 involved in tomato softening was investigated in CRISPR-based knockout mutants of SlXTH5.Loss-of-function of SlXTH5 in transgenic tomato lines resulted in slightly firmer fruit pericarp,but significantly decreased their color index compared with azygous wild type(WT)control fruits.Increased paste viscosity was detected in CRISPR mutants,indicating that the activity of SlXTH5 is responsible for maintaining cell wall structural integrity.Immunocytochemistry studies were performed using the monoclonal antibody probe LM25 to examine the localization and distribution of xyloglucan in the pericarp cells of the CRISPR mutant fruits.The data indicated more xyloglucan was retained in the pericarp of CRISPR mutant fruit than in WT control fruit.This study revealed the link between SlXTH5 and xyloglucan metabolism and indicated the potential of manipulating SlXTH5 to regulate fruit softening. | Duoduo Wang Qianhui Lu Xiaomin Wang Hui Ling Ning Huang | 2023 | Horticultural Plant Journal2023,9,4: | 1 |
| 19 | Evaluation of Cell Type Annotation R Packages on Single-cell RNA-seq显示文摘Annotating cell types is a critical step in single-cell RNA sequencing(scRNA-seq)data analysis.Some supervised or semi-supervised classification methods have recently emerged to enable automated cell type identification.However,comprehensive evaluations of these methods are lacking.Moreover,it is not clear whether some classification methods originally designed for analyzing other bulk omics data are adaptable to scRNA-seq analysis.In this study,we evaluated ten cell type annotation methods publicly available as R packages.Eight of them are popular methods developed specifically for single-cell research,including Seurat,scmap,SingleR,CHETAH,SingleCellNet,scID,Garnett,and SCINA.The other two methods were repurposed from deconvoluting DNA methylation data,i.e.,linear constrained projection(CP)and robust partial correlations(RPC).We conducted systematic comparisons on a wide variety of public scRNA-seq datasets as well as simulation data.We assessed the accuracy through intra-dataset and inter-dataset predictions;the robustness over practical challenges such as gene filtering,high similarity among cell types,and increased cell type classes;as well as the detection of rare and unknown cell types.Overall,methods such as Seurat,SingleR,CP,RPC,and SingleCellNet performed well,with Seurat being the best at annotating major cell types.Additionally,Seurat,SingleR,CP,and RPC were more robust against downsampling.However,Seurat did have a major drawback at predicting rare cell populations,and it was suboptimal at differentiating cell types highly similar to each other,compared to SingleR and RPC.All the code and data are available from http://gffzz188fe103f8f1460askvnoq9o0uu6w6kuf.ffgz.tsg.suse.edu.cn/qianhuiSenn/scRNA_cell_deconv_benchmark. | Qianhui Huang Yu Liu Yuheng Du Lana X.Garmire | 2021 | Genomics, Proteomics & Bioinformatics2021,19,2: | 1 |
| 20 | Image Retrieval Based on Deep Feature Extraction and Reduction with Improved CNN and PCA显示文摘With the rapid development of information technology,the speed and efficiency of image retrieval are increasingly required in many fields,and a compelling image retrieval method is critical for the development of information.Feature extraction based on deep learning has become dominant in image retrieval due to their discrimination more complete,information more complementary and higher precision.However,the high-dimension deep features extracted by CNNs(convolutional neural networks)limits the retrieval efficiency and makes it difficult to satisfy the requirements of existing image retrieval.To solving this problem,the high-dimension feature reduction technology is proposed with improved CNN and PCA quadratic dimensionality reduction.Firstly,in the last layer of the classical networks,this study makes a well-designed DR-Module(dimensionality reduction module)to compress the number of channels of the feature map as much as possible,and ensures the amount of information.Secondly,the deep features are compressed again with PCA(Principal Components Analysis),and the compression ratios of the two dimensionality reductions are reduced,respectively.Therefore,the retrieval efficiency is dramatically improved.Finally,it is proved on the Cifar100 and Caltech101 datasets that the novel method not only improves the retrieval accuracy but also enhances the retrieval efficiency.Experimental results strongly demonstrate that the proposed method performs well in small and medium-sized datasets. | Rongyu Chen Lili Pan Yan Zhou Qianhui Lei | 2020 | Journal of Information Hiding and Privacy Protection2020,2,2: | 1 |
