| 1 | Clinical and Laboratory Findings of Nonacute Neurobrucellosis显示文摘INTRODUCTION Brucellosis is the most common zoonotic infection in the world.It is an endemic disease in many areas throughout the world.Human brucellosis is a multisystem disease that may present with a broad spectrum of clinical manifestations.The central nervous system (CNS) involvement is a rare but serious neurological complication of brucellosis.Neurobrucellosis (NB) often is underdiagnosed,which is partly because of unawareness about the disease among the treating physicians.Clinically nonacute NB is more common than acute NB.Therefore,in order to better understand the nonacute NB,we summarized 14 cases,aimed to shed light to detailed neurologic features of nonacute NB,as well as their laboratory findings. | Li-Dong Jiao Chang-Biao Chu Chhetri Jagadish Kumar Jie Cui Xian-Ling Wang Li-Yong Wu Cun-Jiang Li Xiang-Bo Wang | 2015 | Chinese Medical Journal2015,,13: | 24 |
| 2 | Characteristics and triggering mechanism of Xinmo landslide on 24 June 2017 in Sichuan, China显示文摘At 5: 39 AM on 24 June 2017, a huge landslide-debris avalanche occurred on Fugui Mountain at Xinmo village, Diexi town, Maoxian county, Sichuan province, China. The debris blocked the Songpinggou River for about 2 km, resulting in a heavy loss of both human lives and properties(10 deaths, 3 injuries, 73 missing, and 103 houses completely destroyed). The objectives of this paper are to understand the overall process and triggering factors of this landslide and to explore the affecting factors for its long term evolution before failure. Post event surveys were carried out the day after the landslide occurrence. Information was gathered from literature and on-site investigation and measurement. Topography, landforms, lithology, geological setting, earthquake history, meteorological and hydrological data of the area were analysed. Aerial photographs and other remote sensing information were used for evaluation and discussion. Eye witnesses also provided a lot of helpful information for us to understand the process of initiation, development and deposition. The depositional characteristics of the moving material as well as the traces of the movement,the structural features of the main scarp and the seismic waves induced by the slide are presented and discussed in detail in this paper. The results show that the mechanism of the landslide is a sudden rupture of the main block caused by the instability of a secondary block at a higher position. After the initiation, the failed rock mass at higher position overloaded the main block at the lower elevation and collapsed in tandem. Fragmentation of the rock mass occurred later, thus forming a debris avalanche with high mobility. This landslide case indicates that such seismic events could influence geological hazards for over 80 years and this study provides reference to the long term susceptibility and risk assessment of secondary geological hazards from earthquake. | SU Li-jun HU Kai-heng ZHANG Wei-feng WANG Jiao LEI Yu ZHANG Chong-lei CUI Peng Alessandro PASUTO ZHENG Quan-hong | 2017 | Journal of Mountain Science2017,14,9: | 20 |
| 3 | Status of glycosylated hemoglobin and prediction of glycemic control among patients with insulin-treated type 2 diabetes in North China:a multicenter observational study显示文摘Background:Blood glucose control is closely related to type 2 diabetes mellitus(T2DM)prognosis.This multicenter study aimed to investigate blood glucose control among patients with insulin-treated T2DM in North China and explore the application value of combining an elastic network(EN)with a machine-learning algorithm to predict glycemic control.Methods:Basic information,biochemical indices,and diabetes-related data were collected via questionnaire from 2787 consecutive participants recruited from 27 centers in six cities between January 2016 and December 2017.An EN regression was used to address variable collinearity.Then,three common machine learning algorithms(random forest[RF],support vector machine[SVM],and back propagation artificial neural network[BP-ANN])were used to simulate and predict blood glucose status.Additionally,a stepwise logistic regression was performed to compare the machine learning models.Results:The well-controlled blood glucose rate was 45.82%in North China.The multivariable analysis found that hypertension history,atherosclerotic cardiovascular disease history,exercise,and total cholesterol were protective factors in glycosylated hemoglobin(HbAlc)control,while central adiposity,family history,T2DM duration,complications,insulin dose,blood pressure,and hypertension were risk factors for elevated HbAlc.Before the dimensional reduction in the EN,the areas under the curve of RF,SVM,and BP were 0.73,0.61,and 0.70,respectively,while these figures increased to 0.75,0.72,and 0.72,respectively,after dimensional reduction.Moreover,the EN and machine learning models had higher sensitivity and accuracy than the logistic regression models(the sensitivity and accuracy of logistic were 0.52 and 0.56;RF:0.79,0.70;SVM:0.84,0.73;BP-ANN:0.78,0.73,respectively).Conclusions:More than half of T2DM patients in North China had poor glycemic control and were at a higher risk of developing diabetic complications.The EN and machine learning algorithms are alternative choices,in addition to the traditional logistic model,for building predictive models of blood glucose control in patients with T2DM. | Jiao Wang Meng-Yang Wang Hui Wang Hong-Wei Liu Rui Lu Tong-Qing Duan Chang-Ping Li Zhuang Cui Yuan-Yuan Liu Yuan-Jun Lyu Jun Ma | 2020 | Chinese Medical Journal2020,,1: | 19 |
| 4 | Agriculture Green Development: a model for China and the world显示文摘Realizing sustainable development has become a global priority.This holds,in particular,for agriculture.Recently,the United Nations launched the Sustainable Development Goals(SDGs),and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development.The overall objective of Agriculture Green Development(AGD)is to coordinate'green'with'development'to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity,high resource use efficiency and low environmental impact.This is a formidable task,requiring joint efforts of government,farmers,industry,educators and researchers.The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system,with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being.This paper addresses the significance,challenges,framework,pathways and potential solutions for realizing AGD in China,and highlights the potential changes that will lead to a more sustainable agriculture in the future.Proposals include interdisciplinary innovations,whole food chain improvement and regional solutions.The implementation of AGD in China will provide important implications for the countries in developmental transition,and contribute to global sustainable development. | Jianbo SHEN Qichao ZHU Xiaoqiang JIAO Hao YING Hongliang WANG Xin WEN Wen XU Tingyu LI Wenfeng CONG Xuejun LIU Yong HOU Zhenling CUI Oene OENEMA William JDAVIES Fusuo ZHANG | 2020 | Frontiers of Agricultural Science and Engineering2020,7,1: | 18 |
| 5 | Association of KIR Genotypes and Haplotypes with Susceptibility to Chronic Hepatitis B Virus Infection in Chinese Han Population显示文摘Killer immunoglobulin-like receptor (KIR) genes can regulate the activation of NK and T cells upon interaction with HLA class I molecules. Hepatitis B virus (HBV) infection has been regarded as a multi-factorial disorder disease. Previous studies revealed that KIRs were involved in HCV and HIV infection or clearance. The aim of this study was to explore the possibility of the inheritance of KIR genotypes and haplotypes as a candidate for susceptibility to persistent HBV infection or HBV clearance. The sequence specific primer polymerase chain reaction (SSP-PCR) was employed to identify the KIR genes and pseudogenes in 150 chronic hepatitis B (CHB) patients, 251 spontaneously recovered (SR) controls, and 412 healthy controls. The frequencies of genotype G, M, FZ1 increased in CHB patients compared with healthy control subjects. The frequency of genotype AH was higher in SR controls than that in both CHB patients and healthy controls. The carriage frequencies of genotype G and AH were higher; while, the frequencies of AF and AJ were lower in SR controls than those in healthy control subjects. The frequency of A haplotype was lower, whereas, the frequency of B haplotype was higher in CHB patients and SR controls than those in healthy controls. In healthy controls, haplotype 4 was found lower compared with that in CHB patients and SR controls and the frequency of haplotype 5 was higher in SR controls than that in other two groups. Based on these findings, it seems that the genotypes M and FZ1 are HBV susceptive genotypes; AH, on the other hand, may be protective genotypes that facilitate the clearance of HBV. It appears that the haplotype 4 is HBV susceptive haplotype, whereas, haplotype 5 may be the protective haplotype that facilitates the clearance of HBV. | Zhiming Lu Bingchang Zhang Shijun Chen Zhongtao Gai Zhaolei Feng Xiangdong Liu Yiqing Liu Xin Wen Li Li Yulian Jiao Chunyan Ma Song Shao Xiangfa Cui Guojian Chen Jianfeng Li Yneran Zhao | 2008 | Cellular & Molecular Immunology2008,5,6: | 13 |
| 6 | Modeling of reliability and performance assessment of a dissimilar redundancy actuation system with failure monitoring显示文摘Actuation system is a vital system in an aircraft,providing the force necessary to move flight control surfaces.The system has a significant influence on the overall aircraft performance and its safety.In order to further increase already high reliability and safety,Airbus has implemented a dissimilar redundancy actuation system(DRAS) in its aircraft.The DRAS consists of a hydraulic actuation system(HAS) and an electro-hydrostatic actuation system(EHAS),in which the HAS utilizes a hydraulic source(HS) to move the control surface and the EHAS utilizes an electrical supply(ES) to provide the motion force.This paper focuses on the performance degradation processes and fault monitoring strategies of the DRAS,establishes its reliability model based on the generalized stochastic Petri nets(GSPN),and carries out a reliability assessment considering the fault monitoring coverage rate and the false alarm rate.The results indicate that the proposed reliability model of the DRAS,considering the fault monitoring,can express its fault logical relation and redundancy degradation process and identify potential safety hazards. | Wang Shaoping Cui Xiaoyu Shi Jian Mileta M.Tomovic Jiao Zongxia | 2016 | Chinese Journal of Aeronautics2016,29,3: | 10 |
| 7 | ABNORMAL FLOWER AND GRAIN 1 encodes OsMADS6 and determines palea identity and affects rice grain yield and quality显示文摘The palea and lemma are floral organ structures unique to grasses;these structures form the hull and directly affect grain size and quality. However, the molecular mechanisms controlling the development of the hull are not well understood. In this study, we characterized the rice(Oryza sativa) abnormal flower and grain1(afg1) mutant, a new allele of OsMADS6. Similar to previously characterized osmads6 alleles, in the afg1 floret, the palea lost its marginal region and acquired the lemma identity. However, in contrast to other osmads6 alleles, the afg1 mutant showed altered grain size and grain quality, with decreased total starch and amylose contents, and increased protein and soluble sugar contents. The analysis of transcriptional activity suggested that AFG1 is a transcriptional activator and may affect grain size by regulating the expression levels of several genes related to cell expansion and proliferation in the afg1 mutant. These results revealed that AFG1 plays an important role in determining palea identity and affecting grain yield and quality in rice. | Xiaoqi Yu Saisai Xia Qiankun Xu Yuanjiang Cui Ming Gong Dali Zeng Qiang Zhang Lan Shen Guiai Jiao Zhenyu Gao Jiang Hu Guangheng Zhang Li Zhu Longbiao Guo Deyong Ren Qian Qian | 2020 | Science China(Life Sciences)2020,63,2: | 10 |
| 8 | CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19. | Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 9 |
| 9 | Earthquake-triggered landslides affecting a UNESCO Natural Site:the 2017 Jiuzhaigou Earthquake in the World National Park,China显示文摘On August 8^(th), 2017, an Ms 7.0 magnitude earthquake occurred in Jiuzhaigou County, northern Sichuan Province, China. The Jiuzhaigou Valley World National Park was the most affected area due to the epicentre being located in the scenic area of the park. Understanding the distribution characteristics of landslides triggered by earthquakes to help protect the natural heritage sites in Jiuzhaigou Valley remains a scientific challenge. In this study, a relatively complete inventory of the coseismic landslides triggered by the earthquake was compiled through the interpretation of high-resolution images combined with a field investigation. The results indicate thatcoseismic landslides not only are concentrated in Rize Gulley, Danzu Gully and Zezhawa Gully in the study area but also occur in the front part of Shuzheng Gully along the road network(from the entrance of Jiuzhaigou Valley to Heye Village). The landslides predominantly occur on the east-and southeastfacing slopes in the study area, which is a result of the integrated action of the valley direction and fault movement direction. The back-slope effect and the slope structure caused the difference in coseismic landslide distribution within the three gullies(Danzu Gully, Rize Gully, and Zezhawa Gully) near the inferred fault. In addition, the topographic position index was used to analyse the impact of microlandforms on earthquake-triggered landslides by considering the effect of the slope angle. The study results reveal a higher concentration of landslides in the slope position class of the middle slope(30°-50°) in Jiuzhaigou Valley. These findings can provide scientific guidance for the protection of natural heritage sites and post-disaster reconstruction in Jiuzhaigou Valley. | WANG Jiao JIN Wen CUI Yi-fei ZHANG Wei-feng WU Chun-hao Alessandro PASUTO | 2018 | Journal of Mountain Science2018,15,7: | 8 |

| 13 | Degradation of microcystin-RR in water by chlorine dioxide显示文摘Due to the potent hepatotoxicity and tumor-promoting activity of microcystins, a successful removal of these toxins during drinking water treatment processes is of increasing concern. The oxidation kinetics of MC-RR by chlorine dioxide (ClO2) was studied with HPLC and characterization of the reaction products was performed with UV-spectrometry, TOC and LC-MS. Our experimental results show that the oxidation process is a second order overall and a first order with respect to ClO2 and MC-RR. The activation energy of MC-RR degradation by ClO2 is 53.07 kJ/mol. The rate constant k of the action can be increased by in- creasing temperature and decreasing pH value and ranged from 6.11×102 L/(mol·min) to 5.29×102 L/(mol·min) at pH from 3.44 to 10.41 at 10 ℃. Reaction products were determined to be organic and volatile, because they could be almost removed from aqueous solution by heating for 15 min at 60 ℃ . In addition, the main oxidation products have m/z values of 1072 and are identified as di- hydroxy isomers of MC-RR. | JI Ying HUANG Jun-li FU Jiao WU Ming-song CUI Chong-wei | 2008 | Journal of China University of Mining and Technology2008,18,4: | 6 |

| 16 | Processes of coastal ecosystem carbon sequestration and approaches for increasing carbon sink显示文摘The oceans are the largest carbon pools on Earth, and play the role of a 'buffer' in climate change. Blue carbon, the carbon(mainly organic carbon) captured by marine ecosystems, is one of the important mechanisms of marine carbon storage.Blue carbon was initially recognized only in the form of visible coastal plant carbon sequestration. In fact, microorganisms(phytoplankton, bacteria, archaea, viruses, and protozoa), which did not receive much attention in the past, account for more than 90% of the total marine biomass and are the main contributors to blue carbon. Chinese coastal seas, equivalent to 1/3 of China's total land area, have a huge carbon sink potential needing urgently research and development. In this paper, we focus on the processes and mechanisms of coastal ocean's carbon sequestration and the approaches for increasing that sequestration. We discuss the structures of coastal ecosystems, the processes of carbon cycle, and the mechanisms of carbon sequestration. Using the evolution of coastal ocean's carbon sinks in sedimentary records over geologic times, we also discuss the possible effects of natural processes and anthropogenic activities on marine carbon sinks. Finally, we discuss the prospect of using carbon sequestration engineering for increasing coastal ocean's carbon storage capacity. | ZHANG Yao ZHAO MeiXun CUI Qiu FAN Wei QI JiaGuo CHEN Ying ZHANG YongYu GAO KunShan FAN JingFeng WANG GuangYi YAN ChongLing LU HaoLiang LUO YaWei ZHANG ZiLian ZHENG Qiang XIAO Wei JIAO NianZhi | 2017 | Science China Earth Sciences2017,60,5: | 6 |

| 18 | miR-124 suppresses multiple steps of breast cancer metastasis by targeting a cohort of pro-metastatic genes in vitro显示文摘Metastasis is a multistep process involving modification of morphology to suit migration, reduction of tumor cell adhesion to the extracellular matrix, increase of cell mobility, tumor cell resistance to anoikis, and other steps. MicroRNAs are well-suited to regulate tumor metastasis due to their capacity to repress numerous target genes in a coordinated manner, thereby enabling their intervention at multiple steps of the invasion-metastasis cascade. In this study, we identified a microRNA exemplifying these attributes, miR-124, whose expression was reduced in aggressive MDA-MB-231 and SK-3rd breast cancer cells. Down-regulation of miR-124 expression in highly aggressive breast cancer cells contributed in part to DNA hypermethylation around the promoters of the three genes encoding miR-124. Ectopic expression of miR-124 in MDA-MB-231 cells suppressed metastasis-related traits including formation of spindle-like morphology, migratory capacity, adhesion to fibronectin, and anoikis. These findings indicate that miR-124 suppresses multiple steps of metastasis by diverse mechanisms in breast cancer cells and suggest a potential application of miR-124 in breast cancer treatment. | Xiao-Bin Lv Yu Jiao Yanwei Qing Haiyan Hu Xiuying Cui Tianxin Lin Erwei Song Fengyan Yu | 2011 | Chinese Journal of Cancer2011,30,12: | 6 |
| 19 | Effects of grain size and secondary phase on corrosion behavior and electrochemical performance of Mg-3Al-5Pb-1Ga-Y sacrificial anode显示文摘Grains with size of 4.5—20.5μm were studied for their corrosion behavior and electrochemical performance in a Mg-3 Al-5 Pb-1 Ga-Y sacrificial anode using immersion testing,electrochemical measurements and microstructure analysis.The results show that fine-grained microstructure has higher chemical activity and more negative discharge potentials than coarse-grained samples.The sample with the smallest average grain size of 4.5μm exhibits corrosion current density of 7.473×10-5 A/cm2,and work potentials of-1.721 V at current density of 10 mA/cm2.The density of grain boundaries and LAGBs increases with grain refinement,which leads to higher rates of dissolution and diffusion for the atoms.The secondary phases promote the occurrence of corrosion and improve the chemical activity of alloy due to their higher potential than the substrate.Higher corrosion rate and discharge activity are directly attributed to the higher density of grain boundaries and LAGBs,as well as the secondary phase. | Qiang Cui Danqing Yi Hongxuan Wang Jiayi Zhang Jiao Xu Bin Wang | 2019 | Journal of Rare Earths2019,37,12: | 6 |
| 20 | A Fully Self-Healing Piezoelectric Nanogenerator for Self-Powered Pressure Sensing Electronic Skin显示文摘As an important way of converting mechanical energy into electric energy,a piezoelectric nanogenerator(PENG)has been widely applied in energy harvesting as well as self-powered sensors in recent years.However,its robustness and durability are still severely challenged by frequent and inevitable mechanical impacts in real application environments.Herein,a fully selfhealing PENG(FS-PENG)as a self-powered pressure sensing electronic skin is reported.The self-healing piezoelectric composite and self-healing Ag NW electrode fabricated through mixing piezoelectric PZT particles and conductive Ag NWs into self-healing polydimethylsiloxane(H-PDMS)are assembled into the sandwich structure FS-PENG.The FS-PENG could not only effectively convert external stimulation into electrical signals with a linear response to the pressure but also retain the excellent self-healing and stable sensing property after multiple cycles of cutting and self-healing process.Moreover,a self-healing pressure sensor array composed of 9 FS-PENGs was attached on the back of the human hand to mimic the human skin,and accurate monitoring of the spatial position distribution and magnitude of the pressure was successfully realized. | Maosen Yang Jinmei Liu Dong Liu Jingyi Jiao Nuanyang Cui Shuhai Liu Qi Xu Long Gu Yong Qin | 2021 | Research2021,,1: | 6 |
