| 1 | Flatness Control Based on Dynamic Effective Matrix for Cold Strip Mills显示文摘Steel strips are the main of steel products and flatness is an important quality indicator of steel strips. Flatness control is the key and highly difficult technique of strip mills. The bottle-neck restricting the improvement of flatness control techniques is that the research on flatness theories and control mathematic models is not in accordance with the requirement of technique developments. To build a simple, rapid and accurate explicit formulation control model has become an urgent need for the development of flatness control technique. This paper puts forward the conception of dynamic effective matrix based on the effective matrix method for flatness control proposed by the authors under the consideration of the influence of the change of parameters in rolling processes on the effective matrix, and the concept is validated by industrial productions. Three methods of the effective matrix generation are induced: the calculation method based on the flatness prediction model; the calculation method based on the data excavation in rolling processes and the direct calculation method based on the network model. A fuzzy neural network effective matrix model is built based on the clusters, and then the network structure is optimized and the high-speed-calculation problem of the dynamic effective matrix is solved. The flatness control scheme for cold strip mills is proposed based on the dynamic effective matrix. On stand 5 of the 1 220 mm five-stand 4-high cold strip tandem mill, the industrial experiment with the control methods of tilting roll and bending roll is done by the control scheme of the static effective matrix and the dynamic effective matrix, respectively. The experiment result proves that the control effect of the dynamic effective matrix is much better than that of the static effective matrix. This paper proposes a new idea and method for the dynamic flatness control in the rolling processes of cold strip mills and develops the theory and model of the flatness control effective matrix method. | LIU Hongmin HE Haitao SHAN Xiuying JIANG Guangbiao | 2009 | Chinese Journal of Mechanical Engineering2009，22，2： | 24 |
| 2 | Vertical Vibration of Moving Strip in Rolling Process Based on Beam Theory显示文摘The shape and thickness qualities of strip are influenced by the vibration of rolling mill.At present,the researches on the vibration of rolling mill are mainly the vertical vibration and torsional vibration of single stand mill,the study on the vibration of tandem rolling mill is rare.For the vibration of tandem rolling mill,the key problem is the vibration of the moving strip between stands.In this paper,considering the dynamic of moving strip and rolling theory,the vertical vibration of moving strip in the rolling process was proposed.Take the moving strip between the two mills of tandem rolling mill in the rolling process as subject investigated,according to the theory of moving beam,the vertical vibration model of moving strip in the rolling process was established.The partial differential equation was discretized by Galerkin truncation method.The natural frequency and stability of the moving strip were investigated and the numerical simulation in time domain was made.Simulation results show that,the natural frequency was strongly influenced by the rolling velocity and tension.With increasing of the rolling velocity,the first three natural frequencies decrease,the fourth natural frequency increases;with increasing of the unit tension,when the rolling velocity is high and low,respectively,the low order dimensionless natural frequency gradually decreases and increases,respectively.According to the stability of moving strip,the critical speed was determined,and the matching relationship of the tension and rolling velocity was also determined.This model can be used to study the stability of moving strip,improve the quality of strip and develop new rolling technology from the aspect of dynamics. | SUN Jianliang PENG Yan LIU Hongmin JIANG Guangbiao | 2009 | Chinese Journal of Mechanical Engineering2009，22，5： | 23 |
| 3 | Tobacco, air pollution, environmental carcinogenesis, and thoughts on conquering strategies of lung cancer显示文摘Each year there will be an estimated 2.1 million new lung cancer cases and 1.8 million lung cancer deaths worldwide.Tobacco smoke is the No.1 risk factors of lung cancer,accounting for>85%lung cancer deaths.Air pollution,or haze,comprises ambient air pollution and household air pollution,which are reported to cause 252,000 and 304,000 lung cancer deaths each year,respectively.Tobacco smoke and haze(hereafter,smohaze)contain fine particles originated from insufficient combustion of biomass or coal,have quite similar carcinogens,and cause similar diseases.Smohaze exert hazardous effects on exposed populations,including induction of a large amount of mutations in the genome,alternative splicing of mRNAs,abnormalities in epigenomics,initiation of tumor-promoting chronic inflammation,and facilitating immune escape of transformed cells.Tackling smohaze and development of multi-targets-based preventive and therapeutic approaches targeting smohaze-induced carcinogenesis are the key to conquer lung cancer in the future. | Guangbiao Zhou | 2019 | Cancer Biology & Medicine2019，16，4： | 7 |
| 4 | Translational medicine should translate medical science and technology into health care for everyone in China显示文摘Over the years, a chasm between biomedical researchers and the patients who may benefit from their discoveries has been opened. On one hand, millions of patients with diseas- es such as cancer are anxiously waiting for new remedies to save their lives. On the other hand, many exciting basic science discoveries do not have opportunities to find practi- cal applications. Recently emerging translational medicine aims to tie basic research to clinical results and optimize both patient care and preventive measures. | CHEN Zhu ZHOU GuangBiao | 2011 | Science China(Life Sciences)2011，54，12： | 6 |
| 5 | Back to the spring of 2020: facts and hope of COVID-19 outbreak显示文摘Since December 2019,an atypical pneumonia has occurred in Wuhan,a beautiful city located at the center of China(Fig.1),and the whole country.The origin of the disease remains unclear and the suspected Huanan Seafood Wholesale Market was closed on January 1,2020.Very rapidly,a novel coronavirus was isolated and named first the 2019 novel coronavirus(2019-nCoV)[1]and subsequently severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)[2],and is suggested to be named as human coronavirus 2019(HCoV-19)[3].Meanwhile,the disease is chronologically called pneumonia of unknown origin,novel coronavirus pneumonia(NCP),and coronavirus disease-2019(COVID-19)(Fig.2).Superspreading events of this virus have also taken place on the Diamond Princess cruise off the coast of Yokohama,Japan[4].The Chinese central[5]and local governments[6]have been endeavoring unprecedented efforts to constrain the outbreak,and more than 30000 medical professionals especially doctors and nurses outside Wuhan have been joining the local ones to handle this emergency. | Guangbiao Zhou Saijuan Chen Zhu Chen | 2020 | Frontiers of Medicine2020，14，2： | 5 |
| 6 | Advances in COVID-19:the virus,the pathogenesis,and evidence-based control and therapeutic strategies显示文摘Since the outbreak of the COVID-19 pandemic in early December 2019,81174 confirmed cases and 3242 deaths have been reported in China as of March 19,2020.The Chinese people and government have contributed huge efforts to combat this disease,resulting in significant improvement of the situation,with 58 new cases(34 were imported cases)and 11 new deaths reported on March 19,2020.However,as of March 19,2020,the COVID-19 pandemic continues to develop in 167 countries/territories outside of China,and 128665 confirmed cases and 5536 deaths have been reported,with 16498 new cases and 817 new deaths occurring in last 24 hours.Therefore,the world should work together to fight against this pandemic.Here,we review the recent advances in COVID-19,including the insights in the virus,the responses of the host cells,the cytokine release syndrome,and the therapeutic approaches to inhibit the virus and alleviate the cytokine storm.By sharing knowledge and deepening our understanding of the virus and the disease pathogenesis,we believe that the community can efficiently develop effective vaccines and drugs,and the mankind will eventually win this battle against this pandemic. | Guangbiao Zhou Saijuan Chen Zhu Chen | 2020 | Frontiers of Medicine2020，14，2： | 5 |
| 7 | The first Sinomastodon(Gomphotheriidae,Proboscidea) skull from the Quaternary in China显示文摘The first Sinomastodon(Gomphotheriidae,Proboscidea) skull of the Early Pleistocene,collected from the Renzidong Cave deposits in Anhui Province,Eastern China,is described here as S.jiangnanensis sp.nov.As the only brevirostrine trilophodont gomphotheriid known from the Old World,Sinomastodon was mainly indigenous to China from the Early Pliocene to the Pleistocene.Compared with a few single Pleistocene teeth previously found in China,S.jiangnanensis sp.nov.is represented by a relatively complete skull,mandible and dentition,which is the first discovery of a Quaternary Sinomastodon skull from China.With a brevirostrine,elephant-like skull,no lower tusks,and simple bunodont and trilophodont intermediate molars,the new species is morphologically distinct from other gomphotheres and should belong to the genus Sinomastodon.The new species is more progressive than S.hanjiangensis and the Pliocene type species S.intermedius in its skull and mandible morphology,but is evidently more primitive than the Pleistocene S.yangziensis in its molar morphology.The faunal analysis suggests that the emergence of S.jiangnanensis sp.nov.in Jiangnan area and its southward migration may have been related to a cooling event at the beginning of the Quaternary in Eastern China. | WANG Yuan JIN ChangZhu DENG ChengLong WEI GuangBiao YAN YaLinga | 2012 | Chinese Science Bulletin2012，57，36： | 5 |
| 8 | New discoveries from the classic Quaternary mammalian fossil area of Yanjinggou,Chongqing,and their chronological explanations显示文摘Yanjinggou in Wanzhou District of Chongqing is one of the earliest reported and most famous Quaternary mammalian fossil areas in China.The fauna from this area used to be taken as a benchmark for the biochronological comparison of Quaternary paleontology of South China,but the chronology of this fauna has many controversies for the lack of exact locational and stratigraphical records.The present article,on the basis of recent investigations and discoveries,discusses and explains the distribution and biochronology of the mammalian faunas in the Yanjinggou area.The newly discovered Dayakou fissure fauna,including Rhizomys troglodytes,Homotherium sp.,Panthera pardus,Stegodon orientalis,Dicerorhinus sumatrensis,Hesperotherium sinense,Sus sp.,Cervavitus fenqii,Cervus sp.and Muntiacus sp.,is correlated to the middle Early Pleistocene.The presence of Early Pleistocene mammalian fauna in the Yanjinggou area is therefore confirmed.The'Wanhsien fauna'or'Yenchingkou(=Yanjinggou)fauna'as a Mid-Late Pleistocene biostratigraphical datum should be abandoned.The Dayakou fauna and the Upper Cave fauna of Pingba,both in the Yanjinggou area,are correlated to the middle Early Pleistocene and the early Middle Pleistocene in age,respectively. | CHEN ShaoKun PANG LiBo HE CunDing WEI GuangBiao HUANG WanBo YUE ZongYing ZHANG XiaoHu ZHANG Hua QIN Li | 2013 | Chinese Science Bulletin2013，58，31： | 4 |
| 9 | New materials of the steppe mammoth, Mammuthus trogontherii, with discussion on the origin and evolutionary patterns of mammoths显示文摘Recently found materials indicate that the steppe mammoth, Mammuthus trogontherii, survived in northern China into the late Pleistocene. East Asia is the key area of mammoth evolution after the initial radiation of early forms out of Africa and into Eurasia at the beginning of the late Pliocene (c. 3.5–3.0 Ma). M. rumanus, M. meridionalis, M. trogontherii, and M. primige- nius probably formed a continuous and transitional evolutionary lineage within the pan-Eurasian mammoth radiation in East Asia. Each speciation event of the Eurasian mammoths was followed by a rapid and large-scale dispersal event: out of East Asia. Allopatric speciation is the main speciation pattern of Mammuthus. The climatic vacillation was severe and frequent in East Asia from the early part of early Pleistocene (c. 2.6 Ma) onward, which probably brought about successive speciation in East Asia and the subsequent dispersal of the mammoths. | WEI GuangBiao HU SongMei YU KeFu HOU YaMei LI Xin JIN ChangZhu WANG Yuan ZHAO JianXin WANG WenHua | 2010 | Science China Earth Sciences2010，53，7： | 4 |
| 10 | Identification of an E3 ligase-encoding gene RFWD3 in non-small cell lung cancer显示文摘In order to unveil ubiquitin pathway genes (UPGs) that are essential for non-small cell lung cancer (NSCLC) cell proliferation,we recently conducted a siRNA screening experiment to knockdown the expression of 696 UPGs found in the human genome in A549 and H1975 NSCLC cells.We found that silencing of one of the candidates,RFWD3 that encodes an E3 ubiquitin ligase essential for the repair of DNA interstrand cross-links inresponse to DNA damage,led to dramatic inhibition of NSCLC cell proliferation with significant Z-scores.Knockdown of RFWD3 suppressed colony forming activity of NSCLC cells.We further evaluated the significance of RFWD3 in NSCLCs and found that this gene was more elevated in tumor samples than in paired normal lung tissues and was inversely associated with the clinical outcome of patients with NSCLC.Moreover,RFWD3 expression was significantly higher in smokers than in non-smokers.These results show for the first time that RFWD3 is required for NSCLC cell proliferation and may have an important role in lung carcinogenesis. | Yanfei Zhang Xinchun Zhao Yongchun Zhou Min Wang Guangbiao Zhou | 2020 | Frontiers of Medicine2020，14，3： | 3 |

| 12 | Innate immune checkpoint Siglec10 in cancers:mining of comprehensive omics data and validation in patient samples显示文摘Sialic acid binding Ig-like lectin 10(Siglec10)is a member of innate immune checkpoints that inhibits the activation of immune cells through the interaction with its ligand CD24 on tumor cells.Here,by analyzing public databases containing 64517 patients of 33 cancer types,we found that the expression of Siglec10 was altered in 18 types of cancers and was associated with the clinical outcomes of 11 cancer types.In particular,Siglec10 was upregulated in patients with kidney renal clear cell carcinoma(KIRC)and was inversely associated with the prognosis of the patients.In 131 KIRC patients of our settings,Siglec10 was elevated in the tumor tissues of 83(63.4%)patients compared with that in their counterpart normal kidney tissues.Moreover,higher level of Siglec10 was associated with advanced disease(stages III and IV)and worse prognosis.Silencing of CD24 in KIRC cells significantly increased the number of Siglec10-expressing macrophages phagocytosing KIRC cells.In addition,luciferase activity assays suggested that Siglec10 was a potential target of the transcription factors c-FOS and GATA1,which were identified by data mining.These results demonstrate that Siglec10 may have important oncogenic functions in KIRC,and represents a novel target for the development of immunotherapies. | Chen Zhang Jiandong Zhang Fan Liang Han Guo Sanhui Gao Fuying Yang Hua Guo Guizhen Wang Wei Wang Guangbiao Zhou | 2022 | Frontiers of Medicine2022，16，4： | 2 |
| 13 | The DNMT1-PAS1-PH20 axis drives breast cancer growth and metastasis显示文摘PH20 is a member of the human hyaluronidase family that degrades hyaluronan in the extracellular matrix and controls tumor progression.Inhibition of DNA methyltransferases(DNMTs)leads to elevated hyaluronan levels;however,whether DNMT inhibitors control PH20 remains unclear.Here,we report that the DNMT1 inhibitor,decitabine,suppresses PH20 expression by activating the long non-coding RNA PHACTR2-AS1(PAS1).PAS1 forms a tripartite complex with the RNA-binding protein vigilin and histone methyltransferase SUV39H1.The interaction between PAS1 and vigilin maintains the stability of PAS1.Meanwhile,PAS1 recruits SUV39H1 to trigger the H3K9 methylation of PH20,resulting in its silencing.Functionally,PAS1 inhibits breast cancer growth and metastasis,at least partially,by suppressing PH20.Combination therapy of decitabine and PAS1-30nt-RNA,which directly binds to SUV39H1,effectively blocked breast cancer growth and metastasis in mice.Taken together,DNMT1,PAS1,and PH20 comprise a regulatory axis to control breast cancer growth and metastasis.These findings reveal that the DNMT1-PAS1-PH20 axis is a potential therapeutic target for breast cancer. | Yenan Fu Xi Zhang Xiao Liu Peng Wang Wenhui Chu Wei Zhao Yunling Wang Guangbiao Zhou Yu Yu Hongquan Zhang | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 2 |
| 14 | The Msi1-mTOR pathway drives the pathogenesis of mammary and extramammary Paget’s disease显示文摘Mammary and extramammary Paget’s Diseases(PD)are a malignant skin cancer characterized by the appearance of Paget cells.Although easily diagnosed,its pathogenesis remains unknown.Here,single-cell RNA-sequencing identified distinct cellular states,novel biomarkers,and signaling pathways—including mTOR,associated with extramammary PD.Interestingly,we identified MSI1 ectopic overexpression in basal epithelial cells of human PD skin,and show that Msi1 overexpression in the epidermal basal layer of mice phenocopies human PD at histopathological,single-cell and molecular levels.Using this mouse model,we identified novel biomarkers of Paget-like cells that translated to human Paget cells.Furthermore,single-cell trajectory,RNA velocity and lineage-tracing analyses revealed a putative keratinocyte-to-Paget-like cell conversion,supporting the in situ transformation theory of disease pathogenesis.Mechanistically,the Msi1-mTOR pathway drives keratinocyte-Paget-like cell conversion,and suppression of mTOR signaling with Rapamycin significantly rescued the Paget-like phenotype in Msi1-overexpressing transgenic mice.Topical Rapamycin treatment improved extramammary PD-associated symptoms in humans,suggesting mTOR inhibition as a novel therapeutic treatment in PD. | Yongli Song Christian F.Guerrero-Juarez Zhongjian Chen Yichen Tang Xianghui Ma Cong Lv Xueyun Bi Min Deng Lina Bu Yuhua Tian Ruiqi Liu Ran Zhao Jiuzhi Xu Xiaole Sheng Sujuan Du Yeqiang Liu Yunlu Zhu Shi-jun Shan Hong-duo Chen Yiqiang Zhao Guangbiao Zhou Jianwei Shuai Fazheng Ren Lixiang Xue Zhaoxia Ying Xing Dai Christopher J.Lengner Bogi Andersen Maksim V.Plikus Qing Nie Zhengquan Yu-Show | 2020 | Cell Research2020，30，10： | 2 |
| 15 | Identification of a potential tumor suppressor gene, UBL3, in non-small cell lung cancer显示文摘Objective: Oncogenes have been shown to be drivers of non-small cell lung cancer(NSCLC), yet the tumor suppressing genes involved in lung carcinogenesis remain to be systematically investigated. This study aimed to identify tumor suppressing ubiquitin pathway genes(UPGs) that were critical to lung tumorigenesis.Methods: The 696 UPGs were silenced by an siRNA screening in NSCLC cells;the potential tumor suppressing UPGs were analyzed, and their clinical significance was investigated.Results: We reported that silencing of 11 UPGs resulted in enhanced proliferation of NSCLC cells, and four UPGs(UBL3, TRIM22, UBE2 G2, and MARCH1) were significantly downregulated in tumor samples compared to that in normal lung tissues and their expression levels were positively associated with overall survival(OS) of NSCLC patients. Among these genes, UBL3 was the most significant one. UBL3 expression was decreased in tumor samples compared to that in paired normal lung tissues in 59/86(68.6%) NSCLCs, was correlated with TNM stage and sex of NSCLC patients, and was significantly higher in non-smoking patients than in smoking patients. Silencing UBL3 accelerated cell proliferation and ectopic expression of UBL3 suppressed NSCLC in vitro and in vivo.Conclusions: These results showed that UBL3 represented a tumor suppressor in NSCLC and may have potential for use in therapeutics and for the prediction of clinical outcome of patients. | Xinchun Zhao Yongchun Zhou Qian Hu Sanhui Gao Jie Liu Hong Yu Yanfei Zhang Guizhen Wang Yunchao Huang Guangbiao Zhou | 2020 | Cancer Biology & Medicine2020，17，1： | 2 |
| 16 | A New Family of Galeaspids(Jawless Stem-Gnathostomata) from the Early Silurian of Chongqing, Southwestern China显示文摘A new genus and species of agnathan Eugaleaspidiformes(Galeaspida), Yongdongaspis littoralis gen. et sp. nov., is described from the Llandovery(lower Silurian) Huixingshao Formation at Yongdong Town, Xiushan County, Chongqing, southwestern China. This new Telychian taxon morphologically exhibits some transitional states between Sinogaleaspidae and a cluster of higher eugaleaspidiforms containing Tridensaspidae, Eugaleaspidae, Yunnanogaleaspis, and Nochelaspis, which we term here as the ’eugaleaspid cluster’. Phylogenetic analysis of an extended character matrix of Galeaspida reveals Yongdongaspis, on which Yongdongaspidae fam. nov. is erected, as the sister taxon of this ’eugaleaspid cluster’, supported by two synapomorphies, the presence of one median transverse canal, and two lateral transverse canals leaving from the infraorbital canal. As the first fish described from the Llandovery Huixingshao Formation in Chongqing, Yongdongaspis provides new fossil evidence for the subdivision and correlation of the Upper Red Beds in South China. | CHEN Yang GAI Zhikun LI Qiang WANG Jianhua PENG Lijian WEI Guangbiao ZHU Min | 2022 | Acta Geologica Sinica(English Edition)2022，96，2： | 2 |
