3Expression of fibroblast activation protein in human pancreatic adenocarcinoma and its clinicopathological significance显示文摘AIM: To examine fibroblast activation protein (FAP) expression in pancreatic ductal adenocarcinoma (PDAC) and to analyze its relationship with the clinicopathology of PDAC. METHODS: FAP expression was examined in 134 PDAC specimens by immunohistochemistry, and in four pancreatic cancer cell lines (SW1990, Miapaca-2, AsPC-1 and BxPC-3) by Western blotting assay. We also analyzed the association between FAP expression in PDAC cells and the clinicopathology of PDAC patients. RESULTS: The results showed that the FAP was expressed in both stromal fibroblast cells (98/134, 73.1%) and carcinoma cells (102/134, 76.1%). All 4 pancreatic cancer cell lines expressed FAP protein at different levels. Protein bands corresponding to the proteolytically active 170-kDa seprase dimer and its88-kDa seprase subunit were identif ied. Higher FAP expression in carcinoma cells was associated with tumor size (P < 0.001), fi brotic focus (P = 0.003), perineural invasion (P = 0.009) and worse clinical outcome (P = 0.0085). CONCLUSION: FAP is highly expressed in carcinoma cells and f ibroblasts in PDAC tissues, and its expression is associated with desmoplasia and worse prognosis.Min Shi Dang-Hui Yu Ying Chen Chen-Yan Zhao Jing Zhang Qing-Hua Liu Can-Rong Ni Ming-Hua Zhu 2012World Journal of Gastroenterology2012,18,8:25
4Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems.SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui 2012Science China Earth Sciences2012,55,7:24
5HIF-1α-induced expression of m6A reader YTHDF1 drives hypoxia-induced autophagy and malignancy of hepatocellular carcinoma by promoting ATG2A and ATG14 translation显示文摘N6-methyladenosine(m6A),and its reader protein YTHDF1,play a pivotal role in human tumorigenesis by affecting nearly everystage of RNA metabolism.Autophagy activation is one of the ways by which cancer cells survive hypoxia.However,the possibleinvolvement of m6A modification of mRNA in hypoxia-induced autophagy was unexplored in human hepatocellular carcinoma(HCO).In this study,specific variations in YTHDF1 expression were detected in YTHDF1-overexpressing,knockout,and-knockdownHCC cells,HCC organoids,and HCC patient-derived xenograft(PDX)murine models.YTHDF1 expression and hypoxia inducedautophagy were significantly correlated in vitro;signifhcant overexpression of YTHDF1 in HCC tissues was associated with poorprognosis,Multivariate cox regression analysis identihed YTHDF1 expression as an independent prognostic factor in patients withHCC.Multiple HC models conhrmed that YTHDF1 deficiency inhibited HCC autophagy,growth,and metastasis.Luciferase reporterassays and chromatin immunoprecipitation demonstrated that HlIF-1a regulated YTHDF1 transcription by directly binding to itspromoter region under hypoxia.The results of methylated RNA immunoprecipitation sequencing,proteomics,and polysomeprofling indicated that YTHDF1 contibuted to the translation of autophagy-related genes ATG2A and ATG14 by binding to m6A-modifhed ATG2A and ATG14 mRNA,thus facilitating autophagy and autophagy-related malignancy of HCC.Taken together,HlE-1d-induced YTHDF1 expression was associated with hypoxia-induced autophagy and autophagy-related HCC progression via promoting translation of autophagy-related genes ATG2A and ATG14 in a m6A-dependent manner.Our fndings suggest thatYTHDF1 is a potential prognostic biomarker and therapeutic target for patients with HCC.Qing Li Yong Ni Liren Zhang Runqiu Jiang Jing Xu Hong Yang Yuanchang Hu Jiannan Qiu Liyong Pu Jinhai Tang Xuehao Wang 2021Signal Transduction and Targeted Therapy2021,6,3:24
6Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20

8Infantile hepatic hemangioendothelioma:A clinicopathologic study in a Chinese population显示文摘AIM:To investigate whether the clinicopathologic features of infantile hemangioendothelioma(IHE) of the liver in a Chinese population are similar to the features observed in other races.METHODS:The clinical data,radiological findings,histopathological changes and outcome of 12 cases of IHE diagnosed by the Department of Pathology,West China Hospital over the last 10 years were analyzed retrospectively.Immunohistochemical studies were carried out using antibodies against CD31,CD34,Factor Ⅷ,cytokeratin 8 and cytokeratin 18.RESULTS:The 12 patients were aged from fetal to 5 years(three males and nine females).The tumor was presented with different clinical manifestations,mainly as an asymptomatic,palpable,upper abdominal mass,except for the two fetuses who were detected antena-tally by ultrasound.In one patient,this presentation was accompanied by an initial severe pneumothorax.No symptoms of congestive heart failure were present and neither congenital abnormalities nor vascular tumors in the skin or other organs were found.Laboratory abnormalities included leukocytosis(40%),anemia(60%),thrombocytosis(60%),hyperbilirubinemia(16.7%),abnormal liver function(50%) and increased α-fetoprotein(80%).Based on radiological findings and gross specimens,the tumor presented as a solitary lesion or a multifocal space-occupying lesion.The tumor size ranged from 5.0 cm × 3.5 cm × 2.0 cm to 13.8 cm × 9.0 cm × 7.7 cm,and the 0.2-1.1 cm nodules were diffusely distributed within the multifocal tumor.Seven cases were surgically resected,three cases underwent biopsy and the two fetuses were aborted.Histologically,nine cases were classified as typeⅠ and three as type Ⅱ,presenting aggressive morphologic features,immature vessels,active mitosis and necrosis.An inflammatory component,predominantly eosinophilic granulocytes,sometimes obscured the nature of the tumor.Ten patients are alive after a follow-up of 1-9 years.Based on immunohistochemistry,the endothelial cells in all cases were positive for CD31,CD34 and polyclonal factor Ⅷ antigen,whereas the scattered hyperplasia bile ducts were positive for cytokeratin 8 and cytokeratin 18.CONCLUSION:The clinical manifestations of IHE are non-specific.There is no significant correlation between histological type and prognosis.The clinicopathologic features of IHE in Chinese patients may provide a clue to further evidence-based studies.Zhang Zhang,Hui-Jiao Chen,Wen-Juan Yang,Hong Bu,Bing Wei,Xiao-Yu Long,Jing Fu,Rui Zhang,Yun-Bi Ni,Hong-Ying Zhang,Department of Pathology,West China Hospital,Sichuan University,Guoxuexiang 37,Chengdu 610041,Sichuan Province,China 2010World Journal of Gastroenterology2010,16,36:16
9Sequential Therapy Based on Evolvement of Patterns: A New Model for Treatment of Alzheimer's Disease显示文摘In order to solve the problem of long-term (>9 months) efficacy in the treatment of Alzheimer's disease (AD) by conventional therapy (CT), a staged and multiply-targeted sequential therapy based on the evolvement of patterns (STEP) was developed. Its main innovations include:(1) the time order of evolution of patterns defined by Chinese medicine (CM) in AD was found, that is,'the orderly pattern evolution starting from Shen (Kidney) deficiency, progressing to phlegm, stasis and fire, and worsening to severe toxin as well as functional collapse';(2) the cascade hypothesis of Shen deficiency in AD and its sequential therapy based on Shen-reinforcing was proposed, that is,'reinforcing Shen in the early stage and throughout the whole process, resolving phlegm, activating blood and purging fire in the middle stage, detoxifying and replenishing vitality to stop the collapse in the advanced stage', and through meta-analysis, clinical drug use was optimized, thus the leap from 'inferential selection' to 'evidence-based selection' was realized;(3) the STEP regimen combined with CT maintained cognitive and behavioral stability in AD patients for at least 12 months, with cognitive enhancement and behavioral synergy after 9 months, and cognitive benefit was superior to CT at 9, 12, 15, 18, 21, and 24 months, respectively. The 2-year cognitive improvement rate was increased by 25.64%(P=0.020) and the cognitive deterioration rate was decreased by 48.71%(P=0.000). Among them, the cognitive and functional benefits of Shen-reinforcing therapy for very early AD (350 cases) for 1 year were better than the placebo (P<0.001), and the dementia conversion rate was reduced by 8.85%(P=0.002). The behavioral symptomatic relief of patients with vascular dementia received fire-purging therapy (540 cases) was superior to those received CT (P=0.016). These data suggested that the STEP regimen has synergistic effects on CTs at least in terms of cognitive benefit, and the earlier the use, the greater the benefit will have. Therefore, the STEP regimen should be considered as one of the clinical options, particularly for the dearth of effective pharmaceutical or immunological interventions that are currently available for AD.TIAN Jin-zhou SHI Jing NI Jing-nian WEI Ming-qing ZHANG Xue-kai CHEN Ke-ji WANG Yong-yan 2019Chinese Journal of Integrative Medicine2019,25,8:16
10The ATF/CREB site is the key element for transcription of the human RNA methyltransferase like 1 (RNMTL1) gene, a newly discovered 17p13.3 gene显示文摘The human RNA methyltransferase like i gene (RNMTL1) is one of thirteen newly discovered geneswithin a 116 Kb segment of the chromosome 17p13.3 that suffers from a high frequent loss of heterozygosityin human hepatocellular carcinoma in China[1-5]. To understand the molecular mechanisms underlyingtranscription control of the RNMTL1 gene in human cancers, we decline using of the conventional approachwhere the cis-elements bound by the known transcription factors are primary targets, and carried out thesystematic analyses to dissect the promoter structure and identify/characterize the key cis-elements thatare responsible for its strong expression in cell. The molecular approaches applied included 1, the primerextension for mapping of the transcription starts; 2, the transient transfection/reporter assays on a largenumber of deletion and site-specific mutants of the promoter segment for defining the minimal promoterand the crucial elements within; and 3, the electrophoresis mobility shift assay with specific antibodies forreconfirming the nature of the transcription factors and their cognate cis-elements. We have shown that theinteraction of an ATF/CREB element (-38 to -31) and its cognate transcription factors play a predominantrole in the promoter activity of the RNMTL1 gene. The secondary DNA structures of the ATF/CREBelement play a more vital role in the protein-DNA interaction. Finally, we reported a novel mechanismunderlying the YY1 mediated transcription repression, namely, the ATF/CREB dependent transcription-repression by YY1 is executed in absence of its own sequence-specific binding.JIAN XU JING DE ZHU MIN NI DA FANG WAN JIAN REN GU 2002Cell Research2002,12,4:14

13Ultrasensitive skin‐like wearable optical sensors based on glass micro/nanofibers显示文摘Electronic skin,a class of wearable electronic sensors that mimic the functionalities of human skin,has made remarkable success in applications including health monitoring,human-machine interaction and electronic-biological interfaces.While electronic skin continues to achieve higher sensitivity and faster response,its ultimate performance is fundamentally limited by the nature of low-frequency AC currents.Herein,highly sensitive skin-like wearable optical sensors are demonstrated by embedding glass micro/nanofibers(MNFs)in thin layers of polydimethylsiloxane(PDMS).Enabled by the transition from guided modes into radiation modes of the waveguiding MNFs upon external stimuli,the skin-like optical sensors show ultrahigh sensitivity(1870 k·Pa^-1),low detection limit(7 mPa)and fast response(10μs)for pressure sensing,significantly exceeding the performance metrics of state-of-the-art electronic skins.Electromagnetic interference(EMI)-free detection of high-frequency vibrations,wrist pulse and human voice are realized.Moreover,a five-sensor optical data glove and a 2×2-MNF tactile sensor are demonstrated.These initial results pave the way toward a new category of optical devices ranging from ultrasensitive wearable sensors to optical skins.Lei Zhang Jing Pan Zhang Zhang Hao Wu Ni Yao Dawei Cai Yingxin Xu Jin Zhang Guofei Sun Liqiang Wang Weidong Geng Wenguang Jin Wei Fang Dawei Di Limin Tong 2020Opto-Electronic Advances2020,3,3:12

15Combined effect of the use of carbon fiber and seawater and the molecular structure on the tribological behavior of polymer materials显示文摘The combined effect of the use of carbon fiber and seawater and the molecular structure on the tribological behavior of various polymer materials under natural seawater lubrication was investigated. After the investigation, the wear morphology of the contact surface was observed by a laser scanning confocal microscope, and the texture of the wear scars and tracks were presented in 3 D profiles. Moreover, the mechanism of mixed lubrication and wear resistance was analyzed. The results demonstrated that the friction coefficient of carbon fiber-reinforced polyetheretherketone(CFRPEEK) is the lowest and fluctuates at approximately 0.11. Moreover, the seven polymer materials in ascending order of friction coefficients are CFRPEEK, carbon fiber-reinforced polyamide-imide, polytetrafluoroethylene, polyoxymethylene, polyetheretherketone(PEEK), acrylonitrile butadiene styrene resin, and glass fiber–epoxy resin. More critically, the simultaneous incorporation of deposition, polymeric scrap, hydrophilic groups, and seawater resulted in a decrease in the friction and wear of polymer materials under seawater lubrication. This observation implies that a synergistic friction-reducing and wear-resistant effect exists between carbon fiber, seawater, and the molecular structure of PEEK. As a result, a highly effective polymer material was discovered, CFRPEEK, which has the lowest friction coefficient of 0.11 and lowest wear rate of 2 × 10^(–5) mm^3?(N?m)^(-1) among the polymer materials; this validates the selection of dual friction pairs for seawater hydraulic components.Zhiqiang WANG Jing NI Dianrong GAO 2018Friction2018,6,2:11
16Evaluation of recombinant endostatin in the treatment of atherosclerotic plaques and neovascularization in rabbits显示文摘Objective:Atherosclerotic plaques and neovascularization play an important role in the course of coronary atherosclerosis.This study evaluated the effect of recombinant endostatin on experimental atherosclerotic plaques and neovascularization in rabbits.Methods:Eighteen healthy male rabbits were divided into three groups:control group,atherosclerotic model group,and recombinant endostatin treated group.The atherosclerotic model was established via a high-cholesterol diet after balloon catheter injury.The subject weights,serum total cholesterol,creatine kinase-myocardial band fraction(CKMB),and matrix metalloproteinase-2(MMP-2) were measured.Six weeks after treatment,the aortic roots were taken for pathological assay.The thickness ratio of the intima to media was measured by hematoxylin and eosin(HE) staining,and the number of neovessels was measured by immunohistochemistry via monoclonal antibody CD31 staining.Results:The weight,plasma total cholesterol,and CKMB were not significantly different between the atherosclerotic model group and the recombinant endostatin treated group,but much higher than those of the control group(P<0.05).The thickness ratio of the intima to media in the recombinant endostatin treated group was distinctly less than that in the atherosclerotic model group(P<0.05).The number of neovessels decreased dramatically(P<0.05) and the content of MMP-2 decreased slightly without statistical difference(P>0.05) in the recombinant endostatin treated group,compared to the atherosclerotic model group.Conclusions:Recombinant endostatin is able to inhibit the growth of neovascularization in the atherosclerotic plaque and the development of plaque.Wei MAO Jing KONG Jin DAI Zhao-quan HUANG Dong-zhi WANG Gui-bao NI Min-li CHEN 2010Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010,11,8:11

18High quality reference genome of drumstick tree(Moringa oleifera Lam.), a potential perennial crop显示文摘The drumstick tree(Moringa oleifera Lam.) is a perennial crop that has gained popularity in certain developing countries for its high-nutrition content and adaptability to arid and semi-arid environments. Here we report a high-quality draft genome sequence of M. oleifera. This assembly represents 91.78% of the estimated genome size and contains 19,465 protein-coding genes. Comparative genomic analysis between M. oleifera and related woody plant genomes helps clarify the general evolution of this species, while the identification of several species-specific gene families and positively selected genes in M. oleifera may help identify genes related to M. oleifera's high protein content, fast-growth, heat and stress tolerance. This reference genome greatly extends the basic research on M. oleifera, and may further promote applying genomics to enhanced breeding and improvement of M. oleifera.TIAN Yang ZENG Yan ZHANG Jing YANG Cheng Guang YAN Liang WANG XuanJun SHI ChongYing XIE Jing DAI TianYi PENG Lei ZENG HUAN Yu XU An Ni HUANG YeWei ZHANG JiaJin MA Xiao DONG Yang HAO ShuMei SHENG Jun 2015Science China(Life Sciences)2015,58,7:10
