| 1 | Prevalence of and risk factors for gallstones in Uighur and Han Chinese显示文摘AIM:To perform a single-centre survey of the prevalence of and possible risk factors for gallstones in Uighur and Han Chinese.METHODS:Complete medical data for 9455 patients were collected from the medical centre of our hospital,and the overall prevalence of gallstones as well as the prevalence in different ethnic groups was studied.The risk factors for gallstones in different ethnic groups were identified in a univariate analysis,and variables with statistical significance were analysed by unconditional multiple logistic regression,to primarily explore the similarities and differences in gallstone risk factors between different ethnic groups.RESULTS:The prevalence of gallstones was significantly higher in the Uighur population than in the Hanpopulation(22.87%vs 11.64%,P<0.05).Further analysis of risk factors for gallstones based on the different ethnic areas revealed that age was a risk factor for gallstones in both groups;triglycerides,body-mass index(BMI)and high-density lipoprotein were risk factors for gallstones in the Han population,while total cholesterol(TC),gender and fatty liver were risk factors in the Uighur population.The Uighur patients were older than the Han patients,and had higher BMI,TC,low-density lipoprotein,female rate and fatty liver rate,while the incidence of hypertension was lower than that in the Han patients.CONCLUSION:The prevalence of and risk factors for gallstones differ between the Uighur and Han populations. | Li Zhu Aikebaier Aili Cheng Zhang Aili Saiding Kelimu Abudureyimu Xinjiang Medical University | 2014 | World Journal of Gastroenterology2014，20，40： | 39 |
| 2 | SQUAMOSA Promoter-Binding Protein-Like Transcription Factors:Star Players for Plant Growth and Development显示文摘SQUAMOSA Promoter-Binding Protein-Like (SPL) genes encode plantspecific transcription factors that play important roles in plant phase transition,flower and fruit development,plant architecture,gibberellins signaling,sporogenesis,and response to copper and fungal toxins.In Arabidopsis,many SPL genes are post-transcriptionally regulated by the microRNA (miRNA) miR156,among which AtSPL9 in turn positively regulates the expression of the second miRNA miR172.This miR156AtSPL9-miR172 regulatory pathway plays critical roles during juvenile to adult leaf development and the miR156-SPLs feedback interaction persists all through the plant development,which may be conserved in other plants.In the present paper,we provide a concise review on the most recent progress in the regulatory mechanisms associated with plant SPL transcription factors,especially in relation to miRNAs.The potential application of these discoveries in agriculture is briefly discussed. | Xiaobo Chen Zenglin Zhang Danmei Liu Kai Zhang Aili Li Long Mao | 2010 | Journal of Integrative Plant Biology2010，52，11： | 31 |
| 3 | REE composition in scheelite and scheelite Sm-Nd dating for the Xuebaoding W-Sn-Be deposit in Sichuan显示文摘The scheelite with large size and euhedral shape from Xuebaoding, Sichuan Province is an ideal min- eral to study REE patterns and Sm-Nd dating of non-gold deposits. The scheelite has diameters of 1― 10 cm and colors of pale beige to deep orange. Most of these scheelites occur in association with beryl, cassiterite and muscovite. The rare earth elements indicate that scheelite samples from Xuebaoding W-Sn-Be deposits contain high concentrations of rare earth elements with total ΣREE+Y contents in the range of 369―1725 μg·g?1 and nearly all of these scheelite samples are enriched in LREE and depleted in HREE and have negative Eu anomalies. The REE patterns of the scheelites are similar to those of A-type granite with obvious tetrad effect, similar to that of type II scheelites. Based on reported fluid inclusion studies, the mineralizing-fluid of the Xuebaoding W-Sn-Be deposit indicates low Na activity. The REE patterns of the scheelite are probably controlled by partition coefficient in hydrothermal fluid. In the 147Sm/144Nd-143Nd/144Nd diagram, the scheelites show a linear array corresponding to an isochron age of 182.0±9.2 Ma (MSWD = 0.52). The Sm-Nd age represents the formation age of the scheelite and can indicate that the W, Sn and Be mineralization at Xuebaoding took place in the Early Yanshanian. The Sm-Nd dating result is important for the study of the multi-metal resources in western Sichuan Province. | LIU Yan DENG Jun LI ChaoFeng SHI GuangHai ZHENG AiLi | 2007 | Chinese Science Bulletin2007，52，18： | 25 |

| 6 | Advancement toward Polymer Electrolyte Membrane Fuel Cells at Elevated Temperatures显示文摘Elevation of operational temperatures of polymer electrolyte membrane fuel cells(PEMFCs)has been demonstrated with phosphoric acid-doped polybenzimidazole(PA/PBI)membranes.The technical perspective of the technology is simplified construction and operation with possible integration with,e.g.,methanol reformers.Toward this target,significant efforts have been made to develop acid-base polymer membranes,inorganic proton conductors,and organic-inorganic composite materials.This report is devoted to updating the recent progress of the development particularly of acid-doped PBI,phosphate-based solid inorganic proton conductors,and their composite electrolytes.Long-term stability of PBI membranes has been well documented,however,at typical temperatures of 160℃.Inorganic proton-conducting materials,e.g.,alkali metal dihydrogen phosphates,heteropolyacids,tetravalent metal pyrophosphates,and phosphosilicates,exhibit significant proton conductivity at temperatures of up to 300℃ but have so far found limited applications in the form of thin films.Composite membranes of PBI and phosphates,particularly in situ formed phosphosilicates in the polymer matrix,showed exceptionally stable conductivity at temperatures well above 200℃.Fuel cell tests at up to 260℃ are reported operational with good tolerance of up to 16%CO in hydrogen,fast kinetics for direct methanol oxidation,and feasibility of nonprecious metal catalysts.The prospect and future exploration of new proton conductors based on phosphate immobilization and fuel cell technologies at temperatures above 200℃ are discussed. | Jin Zhang David Aili Shanfu Lu Qingfeng Li and San Ping Jiang | 2020 | Research2020，，1： | 6 |
| 7 | INTERVENTIONAI DIAGNOSIS AND TREATMENT OF VASCULOGENEIC PULSATILE TINNITUS显示文摘Objective To retrospectively study clinical features and diagnostic imaging of vasculogeneic pulsatile tinnitus, and the feasibility and efficacy of transvascular interventional treatment for this condition. Methods Data from 82 cases of arterial or venous pulsatile tinnitus were reviewed. DSA characteristics and possible pathophysiological mechanisms of pulsatile tinnitus in these cases were studied. Diagnoses in this group included intracranial arterovenous fistula(AVF)(n=3), spontaneous skull base dural AVF(n=16), traumatic carotid-cavernous sinus fistula(n=5), subclavian artery stenosis(n=2), internal carotid artery stenosis(n=3), intracranial arterial stenosis(n=1), kinked and/or elongated vertebrobasilar artery(n=2), venous sinus diverticulum(n=2), venous sinus stenosis on the dominant drainage side(n=46) and occipital sinus stenosis(n=2).Treatments included embolization and stenting using coils, NBCA glue, Balt balloons, self-expansion stents and intracranial micro-stents via either the femoral artery or femoral vein. Results Procedures were successful in all cases with no surgery-related complications. Tinnitus disappeared within 2 days after the procedure in all cases. Follow up duration was 5-36 months. Recurrence occurred in 4 cases of arterial tinnitus within 3 months following the initial procedure, which improved after revision embolization or symptom management. There was no recurrence in venous tinnitus cases following stent plastic or stent-coiling embolization treatments. Conclusions Endovascular intervention provides a new approach to the diagnosis and treatment of intractable pulsatile tinnitus. It is also effective in differentiating and studying other types of tinnitus. | LI Baomin CAO Xiangyu LIU Xinfeng LI Sheng WANG Jun LIANG Yongping GE Aili ZHANG Alan FENG Huimin | 2014 | Journal of Otology2014，9，1： | 6 |
| 8 | Development of a multiplex one-step real-time RT-PCR assay for the simultaneous detection of eight viruses associated with febrile rash illnesses显示文摘Fever and rash illnesses(FRIs)are a series of common diseaseswith fever and rashes as clinicalmanifestations,most of which are caused by viral infection.The rashes of FRIs are generally nonspecific;therefore it is difficult to identify FRIassociated viruses solely based on clinical symptoms.To achieve rapid and accurate identification of FRI pathogens,a multiplex one-step real-time reverse transcription-polymerase chain reaction(RT-PCR)assay was developed and evaluated in this study.Primers and probes were selected for the detection of measles virus(MeV),rubella virus(RV),human enterovirus(EV),varicella-zoster virus(VZV),dengue virus(DENV),human parvovirus B19(B19),Epstein-Barr virus(EBV),and human herpes virus 6(HHV-6),which cover the most common pathogenic viruses of FRIs.Detection of the eight FRI-associated viruses,which was divided into two groups/tubes,was simultaneously performed under universal optimized reaction conditions in multiplex one-step real-time RT-PCR assay.The multiplex realtime RT-PCR showed high sensitivity and specificity in detecting the eight FRI-associated viruses.The limits of detection(LODs)for the eight viruses were in the range of 47–177 copies/reaction,and no cross reactions for the eight FRIassociated viruses were found in the multiplex assay.In addition,the results of the multiplex real-time RT-PCR assay were consistent with the results of a monoplex real-time RT-PCR assay and sequencing for clinical specimens obtained from FRI patients.With its advantages of high efficiency and rapid and accurate diagnosis,multiplex real-time RT-PCR was very feasible for the early diagnosis of FRI pathogenic viruses and would be of great help for the proper treatment,monitoring,and initiation of preventive measures for FRI cases. | Aili Cui Shulei Wang Qiang Zhang Huiling Wang Zhen Zhu Aqian Li Qinqin Song Yanzhe Hao Jilan He Wenbo Xu Yan Zhang | 2020 | Biosafety and Health2020，2，2： | 5 |
| 9 | Decadal variations in the season advancement of spring water cycle over Eastern China显示文摘Spring is the critical period for atmospheric circulation transition from winter to summer.The spring water cycle is very im-portant to agriculture in planting crop and the initial growth of crop.Note that there was a significant abrupt decadal change in the water budget increase during early spring over eastern China in the late 1970s.Studied here are the decadal variations of water budgets over the key regions and the associated change of water cycle over East Asia and atmospheric circulation over Asia-West Pacific region in early spring,using the observed(OBS) precipitation,the ECMWF(ERA) and NCEP/NCAR rea-nalysis(NRA),and the Mantua's Pacific decadal oscillation index(PDOI).The water budget increments from March to April exhibited a sharp decrease over the key region around Huaihe River basin(HHR)(111°-120°E;31°-36°N) after year 1978.Before 1977 the water vapor flux through south boundary of the HHR region increased greatly during March to April by 1.52 mm d 1 in ERA and 1.88 mm d 1 in NRA.Concurrently the moisture convergence and precipitation over the region also in-creased greatly.The increment for the moisture convergence was 1.11 mm d 1 in ERA and 1.22 mm d 1 in NRA,and for the precipitation was 1.08 mm d 1 in observation and 1.05 mm d 1 in ERA.April was the time that the water budgets over HHR increased most rapidly before 1977.But after 1978 the water budgets decreased conversely from Mach to April.The water vapor flux increment through the south boundary was 0.03 mm d 1 in ERA and 0.01 mm d 1 in NRA,the moisture conver-gence increment was 0.91 mm d 1 in ERA and 0.53 mm d 1 in NRA,and precipitation increment was 0.08 mm d 1 in ob-servation and 0.15 mm d 1 in ERA.Further investigation has shown that the large-scale atmospheric circulation in the early spring has correspondingly changed significantly after the late 1970s.During March to April,the weakening of the trough over East Asia became significantly slower,and the strengthening of the ridge over the west China became significantly faster in the middle troposphere after the late 1970s.At the same time,in the lower troposphere,the strengthening and northward extending of the west part of the subtropical high and the weakening of the trough over the southwest part of the Aleutian low in the early spring became slower,and the weakening of the main part of Asian high became slower,but the strengthening of its west part became faster.This significant decadal change of circulation caused a sharp decrease in the northward extending speed of wa-ter vapor transport,and in the water budgets increasing speed over the southeastern China during early spring after the late 1970s. | ZHAO RuiXia ZHANG Hong WU GuoXiong LI WeiPing SHI AiLi | 2012 | Science China Earth Sciences2012，55，8： | 4 |
| 10 | Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield显示文摘Diversity surveys of crop germplasm are important for gaining insights into the genomic basis for plant architecture and grain yield improvement,which is still poorly understood in wheat.In this study,we exome sequenced 287 wheat accessions that were collected in the past 100 years.Population genetics analysis identified that 6.7%of the wheat genome falls within the selective sweeps between landraces and cultivars,which harbors the genes known for yield improvement.These regions were asymmetrically distributed on the A and B subgenomes with regulatory genes being favorably selected.Genome-wide association study(GWAS)identified genomic loci associated with traits for yield potential,and two underlying genes,TaARF12 encoding an auxin response factor and TaDEP1 encoding the G-proteinγ-subunit,were located and characterized to pleiotropically regulate both plant height and grain weight.Elite single-nucleotide haplotypes with increased allele frequency in cultivars relative to the landraces were identified and found to have accumulated over the course of breeding.Interestingly,we found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus,leading to propose a“Green Revolution”-based working model for historical wheat breeding.Collectively,our study identifies selection signatures that fine-tune the gibberellin pathway during modern wheat breeding and provides a wealth of genomic diversity resources for the wheat research community. | Aili Li Chenyang Hao Zhenyu Wang Shuaifeng Geng Meiling Jia Fang Wang Xiang Han Xingchen Kong Lingjie Yin Shu Tao Zhongyin Deng Ruyi Liao Guoliang Sun Ke Wang Xingguo Ye Chengzhi Jiao Hongfeng Lu Yun Zhou Dengcai Liu Xiangdong Fu Xueyong Zhang Long Mao | 2022 | Molecular Plant2022，15，3： | 4 |

| 12 | CRISPR/Cas9:A powerful tool for crop genome editing显示文摘The CRISPR/Cas9 technology is evolved from a type II bacterial immune system and represents a new generation of targeted genome editing technology that can be applied to nearly all organisms. Site-specific modification is achieved by a single guide RNA(usually about 20nucleotides) that is complementary to a target gene or locus and is anchored by a protospaceradjacent motif. Cas9 nuclease then cleaves the targeted DNA to generate double-strand breaks(DSBs), which are subsequently repaired by non-homologous end joining(NHEJ) or homology-directed repair(HDR) mechanisms. NHEJ may introduce indels that cause frame shift mutations and hence the disruption of gene functions. When combined with double or multiplex guide RNA design, NHEJ may also introduce targeted chromosome deletions,whereas HDR can be engineered for target gene correction, gene replacement, and gene knock-in. In this review, we briefly survey the history of the CRISPR/Cas9 system invention and its genome-editing mechanism. We also describe the most recent innovation of the CRISPR/Cas9 technology, particularly the broad applications of modified Cas9 variants, and discuss the potential of this system for targeted genome editing and modification for crop improvement. | Gaoyuan Song Meiling Jia Kai Chen Xingchen Kong Bushra Khattak Chuanxiao Xie Aili Li Long Mao | 2016 | The Crop Journal2016，4，2： | 4 |
| 13 | Wheat functional genomics in the era of next generation sequencing: An update显示文摘Bread wheat is not only an important cereal crop but also a model for study of an allopolyploid plant with a large, highly repetitive genome. Advances in next-generation sequencing(NGS) technology provide needed throughput to conquer the enormous size of the wheat genome. Multiple high quality reference genome sequences will soon be available. Full-scale wheat functional genomics studies are dawning. In this review we highlight the available tools and methodologies for wheat functional genomics research developed with the assistance of NGS technology and recent progress, particularly the concerted effort in generating multiple reference genomes, strategies to attain genome-wide genetic variation, genome-wide association studies, mutant population generation, and NGS-supported gene cloning and functional characterization. These resources and platforms lay a solid foundation for wheat research, leading to a new era of wheat functional genomics that will bridge the gap between genotype and phenotype.Dissection of wheat genomes and gene functions should assist in genomics-assisted selection and facilitate breeding of elite varieties for sustainable agriculture in China and the world. | Meiling Jia Jiantao Guan Zhiwen Zhai Shuaifeng Geng Xueyong Zhang Long Mao Aili Li | 2018 | The Crop Journal2018，6，1： | 3 |
| 14 | Impact of polydimethylsiloxanes on physicochemical and tribological properties of naphthenic mineral oil(KN 4010)-based titanium complex grease显示文摘Titanium complex greases were prepared by using naphthenic mineral oil and polydimethylsiloxane as the mixed base oil. The effect of polydimethylsiloxane molecular weight and polydimethylsiloxane content in mixed base oil on the physicochemical and tribological properties of titanium complex greases was investigated.As compared to the sole mineral oil-based titanium complex grease, the use of polydimethylsiloxane(H201-350)as a co-base oil increased the dropping point from 310 to 329℃, decreased the oil separation from 3.7% to 2.3%,reduced the corrosion extent, and obviously improved the tribological properties. When the mixed oil-based titanium complex grease was used as a lubricant, lubricating films of polydimethylsiloxane were probably formed on the surfaces of friction pairs, giving good lubricating property. | Jitai Li Chu Zhai Hengbo Yin Aili Wang Lingqin Shen | 2019 | Chinese Journal of Chemical Engineering2019，27，4： | 3 |
| 15 | Increasing isobutanol yield by double-gene deletion of PDC6 and LPD1 in Saccharomyces cerevisiae显示文摘As a new biofuel, isobutanol has received more attentions in recent years. Because of its high tolerance to higher alcohols, Saccharomyces cerevisiae has potential advantages as a platform microbe to produce isobutanol. In this study, we investigated integration effects of enhancing valine biosynthesis by overexpression of ILV2 and BAT2 with eliminating ethanol formation by deletion of PDC6 and decreasing acetyl-Co A biosynthesis by deletion of LPD1 on isobutanol titers. Our results showed that deletion of LPD1 in strains overexpressing BAT2 and ILV2 increased isobutanol titer by 5.3-fold compared with control strain. Additional deletion of PDC6 in lpd1Δ strains carrying overexpressed BAT2 and ILV2 further increased isobutanol titer by 1.5 fold. Overexpression of BAT2 and ILV2 in lpd1Δ strains and pdc6Δ strains decreased ethanol titers. Glycerol titers of the engineered strains did not have greater changes than that of control strain, while their acetic acid titers were higher, perhaps due to the imbalance of cofactors in isobutanol synthesis. Our researches suggest that double-gene deletion of PDC6 and LPD1 in strains overexpressing BAT2 and ILV2 could increase isobutanol production dramatically than single-gene deletion of PDC6 or LPD1. This study reveals the integration effects of overexpression of ILV2/BAT2 and double-gene deletion of LPD1 and PDC6 on isobutanol production, and helps understanding future developments of engineered strains for producing isobutanol. | Aili Zhang Yang Li Yuhan Gao Hongxing Jin | 2016 | Chinese Journal of Chemical Engineering2016，24，8： | 3 |

| 17 | 2021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://gffzz16e312a87a7141a5ho6wk5wvqqv6566xu.ffgz.tsg.suse.edu.cn/A978). | Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun | 2022 | Chinese Medical Journal2022，，8： | 2 |
| 18 | Numerical simulation of effect of rotational tool with screw on material flow behavior of friction stir welding of Ti6Al4V alloy显示文摘The rotational tool is put forward, which is composed of the one-spiral-flute shoul-der and the rotational pin with screw. Using the turbulent model of the FLUENT software, material plastic flow behavior during the process of friction stir welding of Ti6Al4V alloy is researched by the numerical simulation method and then the effect of rotational tool geometry on material flow during the welding process is attained. The results show that the flow direction of the material near the rotational tool is mainly the same as the rotational direction of the tool while the material near tool flows more violently than the other regions. For the tapered rotational pin, the flow velocity of material inside the workpiece decreases with the increase of the distance away from the workpiece surface because of the change of pin diameter. For the rotational tool, the flute added to the shoulder and the screw added to the pin can greatly increase the flow velocity of material during the welding process while the peak value of the flow velocity of material appears on the flute or the screw. Moreover, the rotational tool with the one-spiral-flute shoulder is better than the tool with the concentric-circles-flute shoulder. Decreasing the width of pin screw and increasing the diameter of pin tip are both good for the increase of flow velocity. | Shude JI Aili ZOU Yumei YUE Guohong L UAN Yanye JIN Fu LI | 2012 | Acta Metallurgica Sinica(English Letters)2012，25，5： | 2 |
| 19 | Divergence in homoeolog expression of the grain length-associated gene GASR7 during wheat allohexaploidization显示文摘Hexaploid wheat has triplicated homoeologs for most of the genes that are located in subgenomes A, B, and D. GASR7, a member of the Snakin/GASA gene family, has been associated with grain length development in wheat. However, little is known about divergence of its homoeolog expression in wheat polyploids. We studied the expression patterns of the GASR7 homoeologs in immature seeds in a synthetic hexaploid wheat line whose kernels are slender like those of its maternal parent(Triticum turgidum, AABB, PI 94655) in contrast to the round seed shape of its paternal progenitor(Aegilops tauschii, DD, AS2404). We found that the B homoeolog of GASR7 was the main contributor to the total expression level of this gene in both the maternal tetraploid progenitor and the hexaploid progeny, whereas the expression levels of the A and D homoeologs were much lower. To understand possible mechanisms regulating different GASR7 homoeologs, we firstly analyzed the promoter sequences of three homoeologous genes and found that all of them contained gibberellic acid(GA) response elements, with the TaG ASR7 B promoter(pT aG ASR7B) uniquely characterized by an additional predicted transcriptional enhancer. This was confirmed by the GA treatment of spikes where all three homoeologs were induced, with a much stronger response for TaG ASR7 B. McrB C enzyme assays showed that the methylation status at pT aG ASR7 D was increased during allohexaploidization, consistent with the repressed expression of TaG ASR7 D. For pT aG ASR7 A, the distribution of repetitive sequence-derived 24-nucleotide(nt) small interfering RNAs(siR NAs) were found which suggests possible epigenetic regulation because 24-nt siR NAs are known to mediate RNA-dependent DNA methylation. Our results thus indicate that both genetic and epigenetic mechanisms may be involved in the divergence of GASR7 homoeolog expression in polyploid wheat. | Dongdong Zhang Bingnan Wang Junmin Zhao Xubo Zhao Lianquan Zhang Dengcai Liu Lingli Dong Daowen Wang Long Mao Aili Li | 2015 | The Crop Journal2015，3，1： | 2 |
