| 1 | Establishment of cell clones with different metastatic potential from the metastatic hepatocellular carcinoma cell line MHCC97显示文摘ALM To establish clone cells with different metastatic potential for the study of metastasis-related mechanisms. METHODS Cloning procedure was performed on parental hepatocellular carcinoma (HCC) cell line MHCC97. andbiological characteristics of the target clones selected by in vivo screening were studied.``RESULTS Two clones with high MHCC97-H and IowMHCC9--L1 metastatic potential were isolated from theparent cell line. Compared with MHCC97-L. MHCC97-H hadsmaller cell size average cell diameter 43 um vs 50 μmand faster in vitro and in vivo growth rate tumor celldoubling time was 34.2 h vs 60.0 h. The main ranges ofchromosomes were 5.5 58 in MHCC97-H and 57 62 inMHCC97-L. Boyden chamber in vitro invasion assay demonstrated that the number of penetrating cells through the artificial basement membrane was 137.5 - 11 .0) cellsfield for MHC_C99--H vs 17.7 - 6.3) field for MHCC97-L.The proportions of cells in GO Gl phase. S phase, and G_ M phase for MHCC97-H MHCC97-L were 0.56 6.65.0.28 0.25 and 0.l6 0.10, respectively, as measured by flow cytometry. The serum AFP levels in nude mice 5 wk after orthotopic implantation of tumor tissue were ( 24666 μg. L for MHCC97-H and (91- 66) μg' L 1 for MHCC97L. The pulmonary metastatic rate was 100% (10-10) vs40% 4- 10).``CONCLUSION Two clones of the same genetic background but with different biological behaviors were established, which could be valuable models for investigation on HCC metastasis. | Yan Li Zhao-You Tang Sheng-Long Ye Yin-Kun Liu Jie Chen Qiong Xue Jun Chen Dong-Mei Gao Wei-Hua Bao Liver Cancer Institute and Zhongshan Hospital of Fudan University (Former Liver Cancer Institute of Shanghai Medical University),Shanghai 200032,China | 2001 | World Journal of Gastroenterology2001，7，5： | 111 |
| 2 | Metastatic human hepatocellular carcinoma models in nude mice and cell line with metastatic potential显示文摘Metastatic human HCC model is needed for the studies on mechanism and intervention of metastatic recurrence. By using orthotopic implantation of histologically intact tissues of 30 surgical specimens, a patient like metastatic model of human HCC in nude mice (LCI-D20)and a Iow metastatic model of human HCC in nude mice LCI-D35 ) have been established. All mice with transplanted LCI-D20 tumors exhibited extremely high metastatic ability including spontaneous metastasis to liver, lungs, lymph nodes and peritoneal seeding.Remarkable difference was also found in expression of some of the invasiveness related genes and growth factors between the LCI-D20 and LCI-D35 tumors. PAI-Iincreased gradually following tumor progression in LCID20 model, and correlated with tumor size and AFP level,Phasic expression of tissue intercellular adhesion molecule-I in this model was also observed. Using corneal micropocket model, it was demonstrated that the vascular response induced by LCI-D20 tumor was stronger than that induced by LCI-D35 tumor. Similar report on metastatic human HCC model in nude mice and human HCC cell line with metastatic potential was rarely found in the literature. This LCI-D20 model has been widely used for the studies on intervention of metastasis, including antiangiogenesis, antisense approach, metalloproteinase inhibitor, differentiation inducer, etc. It is concluded that the establishment of metastatic human HCC model in nude mice and human HCC cell line with metastatic potential will provide important models for the in vivo and in vitro study of HCC invasiveness, angiogenesis as well as intervention of HCC recurrence. | Zhao-You Tang Fan-Xian Sun Jian Tian Sheng-Long Ye Yin-Kun Liu Kang-Da Liu Qiong Xue Jie Chen Jing-Lin Xia Lun-Xiu Qin Hui-Chuan Sun Lu Wang Jian Zhou Yan Li Zeng-Chen Ma Xin-Da Zhou Zhi-Quan Wu Zhi-Ying Lin Bing-Hui Yang Liver Cancer Institute of Fudan University and Zhongshan Hospital,Shanghai 200032,China | 2001 | World Journal of Gastroenterology2001，7，5： | 34 |
| 3 | A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis. | Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao | 2016 | Chinese Journal of Cancer2016，35，6： | 10 |
| 4 | High Cr white cast iron/carbon steel bimetal liner by lost foam casting with liquid-liquid composite process显示文摘Liners in wet ball mill for mineral processing industry must bear abrasive wear and corrosive wear, and consequently,the service life of the liner made from traditional materials,such as Hadfield steel and alloyed steels,is typically less than ten months.Bimetal liner,made from high Cr white cast iron and carbon steel,has been successfully developed by using liquid-liquid composite lost foam casting process.The microstructure and interface of the composite were analyzed using optical microscope,SEM,EDX and XRD.Micrographs indicate that the boundary of bimetal combination regions is staggered like dogtooth,two liquid metals are not mixed,and the interface presents excellent metallurgical bonding state.After heat treatment,the composite liner specimens have shown excellent properties,including hardness>61 HRC,fracture toughnessα k >16.5 J·cm-2 and bending strength >1,600 MPa.Wear comparison was made between the bimetal composite liner and alloyed steel liner in an industrial hematite ball mill of WISCO,and the results of eight-month test in wet grinding environment have proved that the service life of the bimetal composite liner is three times as long as that of the alloyed steel liner. | Xiao Xiaofeng Ye Shengping YinWeixin Zhou Xiaoguang Xue Qiong | 2012 | China Foundry2012，9，2： | 10 |
| 5 | Dopamine D4 Receptor Gene Associated with the Frontal-Striatal-Cerebellar Loop in Children with ADHD: A Resting-State fMRI Study显示文摘Attention deficit hyperactivity disorder(ADHD)is a common childhood neuropsychiatric disorder that has been linked to the dopaminergic system. This study aimed to investigate the effects of regulation of the dopamine D4 receptor(DRD4) on functional brain activity during the resting state in ADHD children using the methods of regional homogeneity(Re Ho) and functional connectivity(FC). Resting-state functional magnetic resonance imaging data were analyzed in 49 children with ADHD. All participants were classified as either carriers of the DRD44-repeat/4-repeat(4 R/4 R) allele(n = 30) or the DRD42-repeat(2 R) allele(n = 19). The results showed that participants with the DRD4 2 R allele had decreased Re Ho bilaterally in the posterior lobes of the cerebellum, while Re Ho was increased in the left angular gyrus. Compared with participants carrying the DRD4 4 R/4 R allele, those with the DRD4 2 R allele showed decreased FC to the left angular gyrus in the left striatum, right inferior frontal gyrus, and bilateral lobes of the cerebellum. The increased FC regions included the left superior frontal gyrus, medial frontal gyrus, and rectus gyrus. These data suggest that the DRD4 polymorphisms are associated with localized brain activity and specific functional connections, including abnormality in the frontal-striatal-cerebellar loop. Our study not only enhances the understanding of the correlation between the cerebellar lobes and ADHD, but also provides an imaging basis for explaining the neural mechanisms underlying ADHD in children. | ANDan Qian Xin Wang Huiru Liu Jiejie Tao Jiejie Zhou Qiong Ye Jiance Li Chuang Yang Jingliang Cheng Ke Zhao Meihao Wang | 2018 | Neuroscience Bulletin2018，34，3： | 10 |

| 9 | Latest Wuchiapingian to Earliest Triassic Conodont Zones and δ13 Ccarb Isotope Excursions from Deep-Water Sections in Western Hubei Province, South China显示文摘Deep-water facies sections have advantages of recording complete information across the Permian-Triassic boundary(PTB). Here we present a detailed study on the conodont biostratigraphy and carbon isotope profile ranges from the Wuchiapingian-Changhsingian boundary(WCB) to the PTB of two deep-water facies sections at Zhuqiao and Shiligou in the Middle Yangtze region, western Hubei, South China. Fifteen species and three genera are identified. Eight conodont zones are recognized which in ascending order are the Clarkina orientalis, C. wangi, C. subcarinata, C. changxingensis, C. yini, C. meishanensis, Hindeodus parvus and Isarcicella isarcica zones. The onset of deposition of the deep-water siliceous strata of Dalong Formation in western Hubei began in the Late Wuchiapingian and persisted to the Late Changhsingian. Carbon isotope negative excursions occur near both the WCB and PTB in both sections. The WCB δ13 Ccarb negative excursion is in the C. orientalis and C. wangi zones. The PTB δ13 Ccarb negative excursion began in the C. yini Zone and extended to the I. isarcica Zone. The absence of several Changhsingian zones may indicate the difficulty of extracting conodonts from siliceous strata or the presence of an intra-Changhsingian hiatus. | Bo Yang Hanxiao Li Paul B.

| 10 | Characterization of astrocytes and microglial cells in the hippocampal CA1 region after transient focal cerebral ischemia in rats treated with Ilexonin A显示文摘Ilexonin A is a compound isolated from the root of Ilex pubescens,a traditional Chinese medicine.Ilexonin A has been shown to play a neuroprotective role by regulating the activation of astrocytes and microglia in the peri-infarct area after ischemia.However,the effects of ilexonin A on astrocytes and microglia in the infarct-free region of the hippocampal CA1 region remain unclear.Focal cerebral ischemia models were established by 2-hour occlusion of the middle cerebral artery in rats.Ilexonin A(20,40 or 80 mg/kg)was administered immediately after ischemia/reperfusion.The astrocyte marker glial fibrillary acidic protein,microglia marker Iba-1,neural stem cell marker nestin and inflammation markers were detected by immunohistochemistry and western blot assay.Expression levels of tumor necrosis factor-αand interleukin 1βwere determined by enzyme linked immunosorbent assay in the hippocampal CA1 tissue.Astrocytes were activated immediately in progressively increasing numbers from 1,3,to 7 days post-ischemia/reperfusion.The number of activated astrocytes further increased in the hippocampal CA1 region after treatment with ilexonin A.Microglial cells remained quiescent after ischemia/reperfusion,but became activated after treatment with ilexonin A.Ilexonin A enhanced nestin expression and reduced the expression of tumor necrosis factor-αand interleukin 1βin the hippocampus post-ischemia/reperfusion.The results of the present study suggest that ilexonin A has a neuroprotective effect in the hippocampus after ischemia/reperfusion,probably through regulating astrocytes and microglia activation,promoting neuronal stem cell proliferation and reducing the levels of pro-inflammatory factors.This study was approved by the Animal Ethics Committee of the Fujian Medical University Union Hospital,China. | Ai-Ling Xu Guan-Yi Zheng Hui-Ying Ye Xiao-Dong Chen Qiong Jiang | 2020 | Neural Regeneration Research2020，15，1： | 5 |
| 11 | Fast-Suppressor Screening for New Components in Protein Trafficking,Organelle Biogenesis and Silencing Pathway in Arabidopsis thaliana Using DEX-Inducible FREE1-RNAi Plants显示文摘Membrane trafficking is essential for plant growth and responses to external signals.The plant unique FYVE domain-containing protein FREE1 is a component of the ESCRT complex(endosomal sorting complex required for transport).FREE1 plays multiple roles in regulating protein trafficking and organelle biogenesis including the formation of intraluminal vesicles of multivesicular body(MVB),vacuolar protein transport and vacuole biogenesis,and autophagic degradation.FREE1 knockout plants show defective MVB formation,abnormal vacuolar transport,fragmented vacuoles,accumulated autophagosomes,and seedling lethality.To further uncover the underlying mechanisms of FREE1 function in plants,we performed a forward genetic screen for mutants that suppressed the seedling lethal phenotype of FREE1-RNAi transgenic plants.The obtained mutants are termed as suppressors of free1(sof).To date,229 putative sof mutants have been identified.Barely detecting of FREE1 protein with M3plants further identified 84 FREE1-related suppressors.Also145 mutants showing no reduction of FREE1 protein were termed as RNAi-related mutants.Through next-generation sequencing(NGS)of bulked DNA from F2mapping population of two RNAi-related sof mutants,FREE1-RNAi T-DNA inserted on chromosome 1 was identified and the causal mutation of putative sof mutant is being identified similarly.These FREE1-and RNAi-related sof mutants will be useful tools and resources for illustrating the underlying mechanisms of FREE1 function in intracellular trafficking and organelle biogenesis,as well as for uncovering the new components involved in the regulation of silencing pathways in plants. | Qiong Zhao Caiji Gao PoShing Lee Lin Liu Shaofang Li Tangjin Hu Jinbo Shen Shuying Pan Hao Ye Yunru Chen Wenhan Cao Yong Cui Peng Zeng Sheng Yu Yangbin Gao Liang Chen Beixin Mo Xin Liu Shi Xiao Yunde Zhao Silin Zhong Xuemei Chen Liwen Jiang | 2015 | Journal of Genetics and Genomics2015，42，6： | 4 |
| 12 | Identification of coastal water quality by multivariate statistical techniques in two typical bays of northern Zhejiang Province,East China Sea显示文摘The Hangzhou Bay(HZB) and Xiangshan Bay(XSB), in northern Zhejiang Province and connect to the East China Sea(ECS) were considerably affected by the consequence of water quality degradation. In this study, we analyzed physical and biogeochemical properties of water quality via multivariate statistical techniques. Hierarchical cluster analysis(HCA) grouped HZB and XSB into two subareas of different pollution sources based on similar physical and biogeochemical properties. Principal component analysis(PCA) identified three latent pollution sources in HZB and XSB respectively and emphasized the importance of terrestrial inputs, coastal industries as well as natural processes in determining the water quality of the two bays. Therefore, proper measurement for the protection of aquatic ecoenvironment in HZB and XSB were of great urgency. | YE Ran LIU Lian WANG Qiong YE Xiansen CAO Wei HE Qinyan CAI Yanhong | 2017 | Acta Oceanologica Sinica2017，36，2： | 4 |
| 13 | The Genomes of the Allohexaploid Echinochloa crus-galli and Its Progenitors Provide Insights into Polyploidization-Driven Adaptation显示文摘The hexaploid species Echinochloa crus-galli is one of the most detrimental weeds in crop fields,especially in rice paddies.Its evolutionary history is similar to that of bread wheat,arising through polyploidization after hybridization between a tetraploid and a diploid species.In this study,we generated and analyzed high-quality genome sequences of diploid(E.haploclada),tetraploid(E.oryzicola),and hexaploid(E.crus-galli)Echinochloa species.Gene family analysis showed a significant loss of disease-resistance genes such as those encoding NB-ARC domain-containing proteins during Echinochloa polyploidization,contrary to their significant expansionduring wheat polyploidization,suggesting that natural selection might favor reduced investment in resistance in this weed to maximize its growth and reproduction.In contrast to the asymmetric patterns of genome evolution observed in wheat and other crops,no significant differences in selection pressure were detected between the subgenomes in E.oryzicola and E.crus-galli.In addition,distinctive differences in subgenome transcriptome dynamics during hexaploidization were observed between E.crus-galli and bread wheat.Collectively,our study documents genomic mechanisms underlying the adaptation of a major agricultural weed during polyploidization.The genomic and transcriptomic resources of three Echinochloa species and new insights into the polyploidization-driven adaptive evolution would be useful for future breeding cereal crops. | Chu-Yu Ye Dongya Wu Lingfeng Mao Lei Jia Jie Qiu Sangting Lao Meihong Chen Bowen Jiang Wei Tang Qiong Peng Lang Pan Lifeng Wang Xiaoxiao Feng Longbiao Guo Chulong Zhang Elizabeth A.Kellogg Kenneth M.Olsen Lianyang Bai Longjiang Fan | 2020 | Molecular Plant2020，13，9： | 4 |
| 14 | Iso-structural phase transition in tetramethylammonium nickel(Ⅱ)nitrite[(CH_3)_4N][Ni(NO_2)_3]显示文摘The title compound,tetramethylammonium nickel nitrite[(CH_3)_4Nl[Ni(NO_2)_3],has a hexagonal perovskite-type structure with formula ABX_3.It undergoes two reversible phase transitions occurring at about 409.1 and 428.4 K,associated with dielectric transitions.DSC measurement and dielectric measurement confirm the transition.The variable-temperature X-ray structural determinations and the powder X-ray diffraction(PXRD) experiments reveal that this compound has the same space group P3 m 1(No.164) at 293 K,413 K and 438 K.The phase transitions are caused by the rotation of the[(CH_3)_4N]^+cation. | Li-Hui Kong Da-Wei Fu Qiong Ye Heng-Yun Ye Yi Zhang Ren-Gen Xiong | 2014 | Chinese Chemical Letters2014，25，6： | 3 |

| 16 | Study on the Dynamics of Blending of Glucomannan with Carrageenan and Guaran Gum显示文摘In order to prove up the interaction between konjac glucomannan (KGM) and other amyloses, by using KGM, guaran gum and carrageenan as materials, their blending in different external conditions was modeled by means of molecular dynamics (MD) method. The result showed that 323 K was a significant turning point for the formation of hydrogen bond, and KGM and guaran gum were just juxtaposed together via intermolecular hydrogen bond; but with the addition of carrageenan, KGM, guaran gum and carrageenan were spirally twisted together, and when their blending proportion is 3:2:9 the combination was the most compact. Moreover, the research result has provided the sequent studies afterwards on amyloses with some references. | PANG Jie YE Bing-Hong HUANG Yong-Mei LIN Qiong ZENG Cui SUN Yuan-Ming | 2007 | Chinese Journal of Structural Chemistry2007，26，8： | 2 |
| 17 | Co-infection of SARS-COV-2 and Influenza A Virus:A Case Series and Fast Review显示文摘Coronavirus disease 2019(COVID-19)occurs in the influenza season and has become a global pandemic.The present study aimed to examine severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)co-infection with influenza A virus(IAV)in an attempt to provide clues for the antiviral interventions of co-infected patients.We described two patients who were co-infected with SARS-CoV-2 and IAV treated at Wuhan Union Hospital,China.In addition,we performed a review in PubMed,Web of Science and CNKI(from January 1 up to November 1,2020)with combinations of the following key words:“COVID-19,SARS-COV-2,influenza A and co-infection”.A total of 28 co-infected patients were enrolled in the analysis.Of the 28 patients,the median age was 54.5 years(IQR,34.25–67.5)and 14 cases(50.0%)were classified as severe types.The most common symptoms were fever(85.71%),cough(82.14%)and dyspnea(60.71%).Sixteen patients had lymphocytopenia on admission and 23 patients exhibited abnormal radiological changes.The median time from symptom onset to hospital admission was 4 days(IQR,3–6),and the median time of hospital stay was 14 days(IQR,8.5–16.75).In conclusion,patients with SARSCOV-2 and IAV co-infection were similar to those infected with SARS-COV-2 alone in symptoms and radiological images.SARS-COV-2 co-infection with IAV could lead to more severe clinical condition but did not experience longer hospital stay compared with patients infected with SARSCOV-2 alone. | Xuan XIANG Zi-hao WANG Lin-lin YE Xin-liang HE Xiao-shan WEI Yan-ling MA Hui LI Long CHEN Xiao-rong WANG Qiong ZHOU | 2021 | Current Medical Science2021，41，1： | 2 |

| 19 | Reduction in interhemispheric functional connectivity in the dorsal visual pathway in unilateral acute open globe injury patients: a resting-state fMRI study显示文摘This study investigated the changes in interhemispheric functional connectivity(FC) of the whole brain in open globe injury(OGI) patients, using voxel-mirrored homotopic connectivity(VMHC), and their relationships with clinical features. Totally, 16 male and 2 female acute OGI patients and 18 sex, age, and education-matched healthy volunteers were enrolled in the study. All subjects were scanned through functional magnetic resonance imaging(f MRI). Receiver operating characteristic(ROC) curves analyses had been used to identify the VMHC in these brain areas could be used as biomarkers to distinguish OGI and from healthy control(HC). The mean VMHC values in multiple brain areas and clinical OGI manifestations were evaluated with a Pearson correlation analysis. OGI patients had significantly decreased VMHC in the bilateral calcarine/lingual/cuneus(BA18, 19, 30) and middle occipital gyrus(BA18, 19). The OGI patients had abnormal interhemispheric FC in the dorsal visual pathway, which may represent the pathophysiological mechanism that underlies acute vision loss after OGI. | Lei Ye Ran Wei Xin Huang Wen-Qing Shi Qi-Chen Yang Qing Yuan Pei-Wen Zhu Nan Jiang Biao Li Qiong Zhou Fu-Qing Zhou Yi Shao | 2018 | International Journal of Ophthalmology(English edition)2018，11，6： | 2 |
| 20 | Real-time fluorescent quantitative immuno-PCR method for determination of fluoranthene in water samples with a molecular beacon显示文摘A reliable and sensitive competitive real-time fluorescent quantitative immuno-PCR (RTFQ-IPCR) assay using a molecular beacon was developed for the determination of trace fluoranthene (FL) in the environment.Under optimized assay conditions,FL can be determined in the concentration range from 1 fg/mL to 100 ng/mL,with y=0.194x + 7.859,and a correlation coefficient of 0.967 was identified,with a detection limit of 0.6 fg/mL.Environmental water samples were successfully analyzed,recovery was between 90% and 116%,with intra-day relative standard deviation (RSD) of 6.7%-12.8% and inter-day RSD of 8.4%-15.2%.The results obtained from RTFQ-IPCR were confirmed by ELISA,showing good accuracy and suitability to analyze FL in field samples.As a highly sensitive method,the molecular beacon-based RTFQ-IPCR is acceptable and promising for providing reliable test results to make environmental decisions. | Qiyan Ye Huisheng Zhuang Chun Zhou Qiong'e Wang | 2010 | Journal of Environmental Sciences2010，22，5： | 2 |
