1m6A RNA methylation-mediated HNF3γreduction renders hepatocellular carcinoma dedifferentiation and sorafenib resistance显示文摘Hepatocyte nuclear factor 3γ(HNF3γ)is a hepatocyte nuclear factor,but its role and clinical significance in hepatocellular carcinoma(HCC)remain unclear.Herein,we report that HNF3γexpression is downregulated in patient HCC and inversely correlated with HCC malignancy and patient survival.Moreover,our data suggested that the HNF3γreduction in HCC could be mediated by METTL14-dependent m6A methylation of HNF3γmRNA.HNF3γexpression was increased during hepatic differentiation and decreased in dedifferentiated HCC cells.Interestingly,HNF3γdelivery promoted differentiation of not only HCC cells but also liver CSCs,which led to suppression of HCC growth.Mechanistic analysis suggested an HNF3γ-centered regulatory network that includes essential liver differentiation-associated transcription factors and functional molecules,which could synergistically facilitate HCC cell differentiation.More importantly,enforced HNF3γexpression sensitized HCC cells to sorafenib-induced growth inhibition and cell apoptosis through transactivation of OATP1B1 and OATP1B3 expression,which are major membrane transporters for sorafenib uptake.Clinical investigation showed that patient-derived HCC xenografts with high HNF3γexpression exhibited a sorafenib response and patients with high HCC HNF3γlevels benefited from sorafenib therapy.Together,these results suggest that HNF3γplays an essential role in HCC differentiation and may serve as a therapeutic target and predictor of sorafenib benefit in patients.Tengfei Zhou Shichao Li Daimin Xiang Junyu Liu Wen Sun Xiuliang Cui Beifang Ning Xiao Li Zhuo Cheng Weiqi Jiang Cheng Zhang Xijun Liang Liang Li Xin Cheng Liu Hui Hongyang Wang Jin Ding 2020Signal Transduction and Targeted Therapy2020,5,1:4
2Permian Tectonic Evolution in the Middle Part of Central Asian Orogenic Belt: Evidence from Newly Identified Volcanic Rocks in the Bilutu Area, Inner Mongolia显示文摘In this study, zircon U-Pb ages, geochemical and Lu-Hf isotopic data are presented for the newly identified volcanic rocks which were considered as Bainaimiao group in Bainaimiao Arc Belt(BAB), Inner Mongolia, which could provide important constraints on the evolution of the northern part of North China Block(NCB) and BAB. Basalt to basaltic andesite and andesite to dacite were collected from two sections, which showed eruption ages of 278.2±4.1 Ma and 258.3±3.0 Ma respectively. All samples are characterized by high abundances in Al2O3, LREEs, and LILEs, but depleted in HFSEs. Together with high Mg# ratios and low K/tholeiite to calc-alkaline series, these features indicated that basalt to andesite was likely derived from relatively low degree partial melting of the subduction-fluid related mantle in the spinel phase. And dacite was mainly from the partial melting of crust, then affected by mantle. All samples barely went through fractional crystallization process with the slight Eu anomaly. Compared with the contemporary basalt in NCB, rocks in BAB have a complex composition of zircon and a more positive εHf(t) value(-6.6-6.4), indicating that they had different magma sources of rocks. Though with different basements, NCB and BAB have become an integrated whole before 278 Ma. Therefore, it could be concluded that NCB and BAB belonged to the active continental margin and the PAO had not closed yet until late Permian and then it disappeared gradually and the CAOB developed into a condition of syn-post collision.WANG Shijie LIU Yang DONG Xiaojie XU Zhongyuan WANG Wenlong LI Shichao SHI Qiang CUI Weilong 2019Acta Geologica Sinica(English Edition)2019,93,5:3
3Nutritional status in chronically hospitalized stroke patients complicated with pulmonary infection显示文摘Complicated pulmonary infection following stroke has traditionally been considered an aspirated infection by many physicians,and little attention has been paid to concomitant protein-energy malnutrition.In the present study,we hypothesized that protein-energy malnutrition may be present in hospitalized chronic stroke patients complicated with pulmonary infection.The results revealed that body protein and fat stores were significantly depleted in stroke patients with pulmonary infection.Protein-energy malnutrition was present in 12 of 27 patients with pulmonary infection.In comparison,only eight of 42 stroke patients without pulmonary infection exhibited protein-energy malnutrition.A significantly higher prevalence of protein-energy malnutrition was found in the pulmonary infection group,suggesting that protein-energy malnutrition is more likely to be present in hospitalized chronic stroke patients with pulmonary infection.Yue Chen Lufang Chen Yiqing Tao Maomao Han Chunlan Cui Shichao Liu 2011Neural Regeneration Research2011,6,13:0
4A new method of searching for concealed Au deposits by using the spectrum of arid desert plant species显示文摘With the increase of exploration depth,it is more and more difficult to find Au deposits.Due to the limitation of time and cost,traditional geological exploration methods are becoming increasingly difficult to be effectively applied.Thus,new methods and ideas are urgently needed.This study assessed the feasibility and effectiveness of using hyperspectral technology to prospect for hidden Au deposits.For this purpose,48 plant(Seriphidium terrae-albae)and soil(aeolian gravel desert soil)samples were first collected along a sampling line that traverses an Au mineralization alteration zone(Aketasi mining region in an arid region of China)and were used to obtain soil Au contents by a chemical analysis method and the reflectance spectra of plants obtained with an Analytical Spectral Device(ASD)FieldSpec3 spectrometer.Then,the corresponding relationship between the soil Au content anomaly and concealed Au deposits was investigated.Additionally,the characteristic bands were selected from plant spectra using four different methods,namely,genetic algorithm(GA),stepwise regression analysis(STE),competitive adaptive reweighted sampling(CARS),and correlation coefficient method(CC),and were then input into the partial least squares(PLS)method to construct a model for estimating the soil Au content.Finally,the quantitative relationship between the soil Au content and the 15 different plant transformation spectra was established using the PLS method.The results were compared with those of a model based on the full spectrum.The results obtained in this study indicate that the location of concealed Au deposits can be predicted based on soil geochemical anomaly information,and it is feasible and effective to use the full plant spectrum and PLS method to estimate the Au content in the soil.The cross-validated coefficient of determination(R2)and the ratio of the performance to deviation(RPD)between the predicted value and the measured value reached the maximum of 0.8218 and 2.37,respectively,with a minimum value of 6.56μg/kg for the root-mean-squared error(RMSE)in the full spectrum model.However,in the process of modeling,it is crucial to select the appropriate transformation spectrum as the input parameter for the PLS method.Compared with the GA,STE,and CC methods,CARS was the superior characteristic band screening method based on the accuracy and complexity of the model.When modeling with characteristic bands,the highest accuracy,R2 of 0.8016,RMSE of 7.07μg/kg,and RPD of 2.20 were obtained when 56 characteristic bands were selected from the transformed spectra(1/lnR)'(where it represents the first derivative of the reciprocal of the logarithmic spectrum)of sampled plants using the CARS method and were input into the PLS method to construct an inversion model of the Au content in the soil.Thus,characteristic bands can replace the full spectrum when constructing a model for estimating the soil Au content.Finally,this study proposes a method of using plant spectra to find concealed Au deposits,which may have promising application prospects because of its simplicity and rapidity.CUI Shichao ZHOU Kefa ZHANG Guanbin DING Rufu WANG Jinlin CHENG Yinyi JIANG Guo 2021Journal of Arid Land2021,13,11:0
5Estimation of copper concentration of rocks using hyperspectral technology显示文摘Rock geochemical information is important for mineral exploration and provides a theoretical basis for the rapid delineation of hidden minerals. Remote sensing technology provides the possibility of rapid and large-scale extraction of geochemical information from the earth’s surface. This study analyzed the relationship between copper concentration and rock spectra by first collecting 222 rock samples, and then measuring the copper concentration of rock samples in the laboratory and reflectance spectra using an ASD FieldSpec3 portable spectrometer. It finally established quantitative relationships between the original spectra, first-order derivative spectra and second-order derivative spectra and copper concentration, respectively, using the partial least squares support vector machine method (PLS-SVM). The results show that 1) The estimation accuracy of using second-order derivatives spectra as input parameters to establish a model for estimating copper concentration is the highest, and the determined coefficient (R2) between the predicted value and real value reaches 0.54. 2) When the copper concentration is less than 80 mg/kg, the inversion model of copper concentration established using PLS-SVM obtains a good result. The R2 between the predicted copper concentration and the real copper concentration reached 0.70248. When the copper concentration is greater than 80 mg/kg, the inversion model of copper concentration established using partial least squares (PLS) obtains a good result. The R2 between the predicted copper concentration and the real copper concentration reached 0.49. The R2 between real copper concentration and copper predicted by the method of piecewise separate modeling reaches 0.816.Therefore, the method of segmental modeling has great potential to improve the accuracy of copper concentration inversion.Shichao CUI Kefa ZHOU Rufu DING 2019Frontiers of Earth Science2019,13,3:0
6Multiomics comparison among populations of three plant sources of Amomi Fructus显示文摘Amomi Fructus(Sharen,AF)is a traditional Chinese medicine(TCM)from three source species(or varieties),including Wurfbainia villosa var.villosa(WVV),W.villosa var.xanthioides(WVX),or W.longiligularis(WL).Among them,WVV has been transplanted from its top-geoherb region,Guangdong,to its current main production area,Yunnan,for>50 years in China.However,the genetic and transcriptomic differentiation among multiple AF source species(or varieties)and between the origin and transplanted populations of WVV is unknown.In our study,the observed overall higher expression of terpenoid biosynthesis genes in WVV than in WVX provided possible evidence for the better pharmacological effect of WVV.We also screened six candidate borneol dehydrogenases(BDHs)that potentially catalyzed borneol into camphor in WVV and functionally verified them.Highly expressed genes at the P2 stage of WVV,Wv05G1424 and Wv05G1438,were capable of catalyzing the formation of camphor from(+)-borneol,(-)-borneol and DL-isoborneol.Moreover,the BDH genes may experience independent evolution after acquiring the ancestral copies,and the following tandem duplications might account for the abundant camphor content in WVV.Furthermore,four populations of WVV,WVX,and WL are genetically differentiated,and the gene flow from WVX to WVV in Yunnan contributed to the greater genetic diversity in the introduced population(WVV-JH)than in its top-geoherb region(WVV-YC),which showed the lowest genetic diversity and might undergo genetic degradation.In addition,terpene synthesis(TPS)and BDH genes were selected among populations of multiple AF source species(or varieties)and between the top-and non-top-geoherb regions,which might explain the difference in metabolites between these populations.Our findings provide important guidance for the conservation,genetic improvement,and industrial development of the three source species(or varieties)and for identifying top-geoherbalism with molecular markers,and proper clinical application of AF.Xinlian Chen Shichao Sun Xiaoxu Han Cheng Li Fengjiao Wang Bao Nie Zhuangwei Hou Song Yang Jiaojiao Ji Ge Li Yanqian Wang Xiaoyu Han Jianjun Yue Cui Li Wei Li Lixia Zhang Depo Yang Li Wang 2023Horticulture Research2023,10,8:0
7Preparation and corrosion protection performance of a pulse co-deposited Ni/Co/SiO_(2) hydrophobic composite coating显示文摘Ni/Co/SiO_(2) hydrophobic coatings were fabricated by embedding SiO_(2) nanoparticles into Ni/Co coatings using pulsed electrodeposition,followed by a liquid-phase hydrophobic treatment.Microstructure and morphology analysis of the composite coatings revealed that the SiO_(2) nanoparticles were homogenously distributed in the Ni/Co coating,and the surfaces of the samples were close-grained without crack.Furthermore,the SiO_(2) nanoparti-cles in the coating formed micro-nano structures on its surface,such that the contact angle reached 125°following the hydrophobic modification.The surface of the hydrophobic coating was found to be abrasion resistant and ex-hibited long-term stability in water.The corrosion inhibition efficiency of the Ni/Co/SiO_(2) hydrophobic coatings on a Q235 carbon steel substrate in simulated seawater solution reached 98.6%,indicating optimal anti-corrosion performance.Gaoqun Qiao Shichao Wang Xiaohu Wang Xiaoyan Chen Xinzhen Wang Hongzhi Cui 2022ChemPhysMater2022,1,2:0
8Post-stroke seizures in consecutive elderly stroke patients显示文摘This prospective study sought to investigate the clinical,radiological and electroencephalographic(EEG) characteristics of seizures in elderly stroke patients,and their outcomes.Over a 2-year study period,158 consecutive elderly patients with stroke were examined and followed up.Of these patients,32(20%) developed seizures,primarily related to stroke,within a follow up period between 5 months and 2 years.Of these 32 cases,20 experienced infarctions,and 12 experienced hemorrhages.Involvement of cortical regions was detected in most of the patients exhibiting seizures.In these patients,44% of the lesions involved cortical areas exclusively or in addition to subcortical areas observed on computed tomography(CT) images.Twenty-five patients(78%) developed early seizures(within 2 weeks after stroke),and half exhibited immediate post-stroke seizures.None of the patients exhibiting early onset seizures developed recurrent seizures or epilepsy,while 57% of late onset seizures(four cases) developed epilepsy.No specific EEG patterns were apparent in those who later developed epilepsy.Overall,early onset seizures after stroke were found to be relatively common,and did not affect outcome.Late onset seizures were less common,but were associated with chronic epilepsy.Yue Chen Lufang Chen Yiqing Tao Maomao Han Chunlan Cui Shichao Liu 2011Neural Regeneration Research2011,6,9:0

10Early rehabilitation and neuroprotective drug therapy outcomes in elderly patients with acute stroke显示文摘Sixty elderly patients, who suffered from acute stroke and were admitted within a 1-year period to the Department of Geriatrics in the First Affiliated Hospital of School of Medicine, Zhejiang University, China, underwent early rehabilitation in combination with neuroprotective drug therapy. Limb movement, cognitive functions and daily life self-care ability in elderly patients upon admission and discharge were assessed using the Hunt-Hess scale, functional independence measures and mini-mental state examination. The mean duration of hospital stay among the 60 patients was 35 days. Upon discharge, 42 (75%) of the patients exhibited cognitive impairment to varying degrees, and 25 (45%) of the 56 stroke patients who underwent rehabilitation evaluation attained independence in daily living activities, 11 (20%) required intermittent supervision, and 20 (36%) required 24-hour constant supervision during performance of these activities. Results demonstrated that early rehabilitation treatment in combination with neuroprotective therapy for acute stroke was effective.Yue Chen Lufang Chen Yiqing Tao Feixue Zhou Chunlan Cui Shichao Liu 2011Neural Regeneration Research2011,6,11:0
11Optimal bandwidth selection for retrieving Cu content in rock based on hyperspectral remote sensing显示文摘Hyperspectral remote sensing technology is widely used to detect element contents because of its multiple bands,high resolution,and abundant information.Although researchers have paid considerable attention to selecting the optimal bandwidth for the hyperspectral inversion of metal element contents in rocks,the influence of bandwidth on the inversion accuracy are ignored.In this study,we collected 258 rock samples in and near the Kalatage polymetallic ore concentration area in the southwestern part of Hami City,Xinjiang Uygur Autonomous Region,China and measured the ground spectra of these samples.The original spectra were resampled with different bandwidths.A Partial Least Squares Regression(PLSR)model was used to invert Cu contents of rock samples and then the influence of different bandwidths on Cu content inversion accuracy was explored.According to the results,the PLSR model obtains the highest Cu content inversion accuracy at a bandwidth of 35 nm,with the model determination coefficient(R^(2))of 0.5907.The PLSR inversion accuracy is relatively unaffected by the bandwidth within 5-80 nm,but the accuracy decreases significantly at 85 nm bandwidth(R^(2)=0.5473),and the accuracy gradually decreased at bandwidths beyond 85 nm.Hence,bandwidth has a certain impact on the inversion accuracy of Cu content in rocks using the PLSR model.This study provides an indicator argument and theoretical basis for the future design of hyperspectral sensors for rock geochemistry.MA Xiumei ZHOU Kefa WANG Jinlin CUI Shichao ZHOU Shuguang WANG Shanshan ZHANG Guanbin 2022Journal of Arid Land2022,14,1:0
12A cluster of mutagenesis revealed an osmotic regulatory role of the OsPIP1 genes in enhancing rice salt tolerance显示文摘Aquaporins play important regulatory roles in improving plant abiotic stress tolerance.To better understand whether the Os PIP1 genes collectively dominate the osmotic regulation in rice under salt stress,a cluster editing of the Os PIP1;1,Os PIP1;2 and Os PIP1;3 genes in rice was performed by CRISPR/Cas9 system.Sequencing showed that two mutants with Cas9-free,line 14 and line 18 were successfully edited.Briefly,line 14 deleted a single C base in both the Os PIP1;1 and Os PIP1;3 genes,and inserted a single T base in the Os PIP1;2 gene,respectively.While line 18 demonstrated an insertion of a single A base in the Os PIP1;1gene and a single T base in both the Os PIP1;2 and Os PIP1;3 genes,respectively.Multiplex editing of the Os PIP1 genes significantly inhibited photosynthetic rate and accumulation of compatible metabolites,but increased MDA contents and osmotic potentials in the mutants,thus delaying rice growth under salt stress.Functional loss of the Os PIP1 genes obviously suppressed the expressions of the Os PIP1,Os SOS1,Os CIPK24 and Os CBL4 genes,and increased the influxes of Na+and effluxes of K^(+)/H^(+)in the roots,thus accumulating more Na+in rice mutants under salt stress.This study suggests that the Os PIP1 genes are essential modulators collectively contributing to the enhancement of rice salt stress tolerance,and multiplex editing of the Os PIP1 genes provides insight into the osmotic regulation of the PIP genes.Leyuan Tao Bing Wang Shichao Xin Wei Li Shengcai Huang Laihua Liu Jing Cui Qianru Zhang Xianguo Cheng 2023The Crop Journal2023,11,4:0
