1青藏高原东部上地幔各向异性及相关的壳幔耦合型式显示文摘对国家数字地震台网和云南、四川、甘肃、青海区域数字地震台网,以及布设在川、滇、藏地区的宽频带流动地震台网共116个台站所记录的远震SKS波形资料作偏振分析,采用叠加分析方法求得每一个台站的SKS快波偏振方向和快慢波的时间延迟,获得青藏高原东部及其邻近地区的上地幔各向异性图像.将该地区全球定位系统(GPS)的观测结果与上地幔各向异性分布相结合作地壳一地幔耦合变形的分析,研究表明青藏高原内部和高原外部的云南地区具有不同的壳幔变形特征,在高原的东缘地区(大致位于川滇西部的26°-27°N之间)存在一个壳幔变形的横向过渡带.过渡带以南地区的快波偏振方向从滇西南的S60°-70°E逐渐转变到滇东南的近东西向,以北的滇西北部和川西南部,快波偏振方向为近似的南北向.高原内部表现为强壳幔耦合型,高原外部则属于壳幔解耦型.这一横向过渡带与地表的断裂走向不一致,但在地壳和上地幔,其地球物理场(如:地壳厚度,布格重力异常和构造应力方向等)都具有横向过渡的特征.该横向过渡带邻近东喜马拉雅构造结,在板块边界动力学上有着重要的意义.王椿镛 常利军 吕智勇 秦嘉政 苏伟 Paul Silver Lucy Flesch 2007中国科学(D辑)2007,37,4:68
2Risk for gastric neoplasias in patients with chronic atrophic gastritis:A critical reappraisal显示文摘Chronic atrophic gastritis (CAG) is an inflammatory condition characterized by the loss of gastric glandular structures which are replaced by connective tissue (non-metaplastic atrophy) or by glandular structures inappropriate for location (metaplastic atrophy).Epidemiological data suggest that CAG is associated with two different types of tumors:Intestinal-type gastric cancer (GC) and type Ⅰ gastric carcinoid (TⅠGC).The pathophysiological mechanisms which lead to the development of these gastric tumors are different.It is accepted that a multistep process initiating from Helicobacter pylori-related chronic inflammation of the gastric mucosa progresses to CAG,intestinal metaplasia,dysplasia and,finally,leads to the development of GC.The TⅠGC is a gastrin-dependent tumor and the chronic elevation of gastrin,which is associated with CAG,stimulates the growth of enterochromaffin-like cells with their hyperplasia leading to the development of TⅠGC.Thus,several events occur in the gastric mucosa before the development of intestinal-type GC and/or TⅠGC and these take several years.Knowledge of CAG incidence from superficial gastritis,its prevalence in different clinical settings and possible risk factors associated with the progression of this condition to gastric neoplasias are important issues.This editorial intends to provide a brief review of the main studies regarding incidence and prevalence of CAG and risk factors for the development of gastric neoplasias.Lucy Vannella Edith Lahner Bruno Annibale 2012World Journal of Gastroenterology2012,18,12:73

8Seismic anisotropy of upper mantle in eastern Tibetan Plateau and related crust-mantle coupling pattern显示文摘By using the polarization analysis of teleseismic SKS waveform data recorded at 116 seismic stations which respectively involved in China National Digital Seismograph Network, and Yunnan, Sichuan, Gansu and Qinghai regional digital networks, and portable broadband seismic networks deployed in Sichuan, Yunnan and Tibet, we obtained the SKS fast-wave direction and the delay time between fast and slow waves of each station by use of the stacking analysis method, and finally acquired the fine image of upper mantle anisotropy in the eastern Tibetan Plateau and its adjacent regions. We analyzed the crust-mantle coupling deformation on the basis of combining the GPS observation results and the upper mantle anisotropy distribution in the study area. The Yunnan region out of the plateau has dif-ferent features of crust-mantle deformation from the inside plateau. There exists a lateral transitional zone of crust-mantle coupling in the eastern edge of the Tibetan Plateau, which is located in the region between 26° and 27°N in the west of Sichuan and Yunnan. To the south of transitional zone, the fast-wave direction is gradually turned from S60°―70°E in southwestern Yunnan to near EW in south-eastern Yunnan. To the north of transitional zone in northwestern Yunnan and the south of western Sichuan, the fast-wave direction is nearly NS. From crust to upper mantle, the geophysical parameters (e.g. the crustal thickness, the Bouguer gravity anomaly, and tectonic stress direction) show the feature of lateral variation in the transitional zone, although the fault trend on the ground surface is inconsis-tent with the fast-wave direction. This transitional zone is close by the eastern Himalayan syntaxis, and it may play an important role in the plate boundary dynamics.Paul SILVER Lucy FLESCH 2007Science China Earth Sciences2007,50,8:33
9中国大陆上地幔各向异性和壳幔变形模式显示文摘近10年来,中国布设的宽频带地震台站大幅度增加.宽频带地震记录中含有大量的剪切波分裂信息,它在揭示中国大陆上地幔的各向异性特征起重要作用.本文对这些台站的远震SKS和(或)SKKS记录,采用最小切向能量的分析方法,确定各台站剪切波分裂的快波偏振方向和延迟时间.此外,还收集了前人在中国大陆及其周边地区的剪切波分裂研究的部分结果,形成拥有1020个剪切波分裂参数对的数据集.这些分裂参数展示了复杂的上地幔各向异性图像.统计分析表明,中国大陆存在较强的上地幔各向异性,平均的剪切波时间延迟为0.95 s,其中西部地区为1.01 s,东部地区为0.92 s.西部地区的各向异性强度略大于东部地区.在大尺度意义下,青藏高原及天山地区,其SKS波分裂和地表变形数据共同支持岩石圈变形模式,即地壳与岩石圈地幔是连贯变形的;东部地区的平均快波偏振方向近似平行于绝对板块运动方向,上地幔各向异性归因于软流圈流动.中部的鄂尔多斯至四川盆地一带为东、西部两种变形模式的过渡带,各向异性结构较为复杂,表现为'化石'各向异性和(或)双层各向异性.印度板块和欧亚板块的碰撞是中国大陆西部上地幔各向异性的主要影响因素,东部地区则与太平洋板块和菲律宾板块向欧亚板块俯冲有关.王椿镛 常利军 丁志峰 刘琼林 廖武林 Lucy M FLESCH 2014中国科学:地球科学2014,44,1:31
10Upper mantle anisotropy and crust-mantle deformation pattern beneath the Chinese mainland显示文摘Over the past 10 years,the number of broadband seismic stations in China has increased significantly.The broadband seismic records contain information about shear-wave splitting which plays an important role in revealing the upper mantle anisotropy in the Chinese mainland.Based on teleseismic SKS and SKKS phases recorded in the seismic stations,we used the analytical method of minimum transverse energy to determine the fast wave polarization direction and delay time of shear-wave splitting.We also collected results of shear-wave splitting in China and the surrounding regions from previously published papers.From the combined dataset we formed a shear-wave splitting dataset containing 1020 parameter pairs.These splitting parameters reveal the complexity of the upper mantle anisotropy image.Our statistical analysis indicates stronger upper mantle anisotropy in the Chinese mainland,with an average shear-wave time delay of 0.95 s;the anisotropy in the western region is slightly larger(1.01 s)than in the eastern region(0.92 s).On a larger scale,the SKS splitting and surface deformation data in the Tibetan Plateau and the Tianshan region jointly support the lithospheric deformation mode,i.e.the crust-lithospheric mantle coherent deformation.In eastern China,the average fast-wave direction is approximately parallel to the direction of the absolute plate motion;thus,the upper mantle anisotropy can be attributed to the asthenospheric flow.The area from the Ordos block to the Sichuan Basin in central China is the transition zone of deformation modes between the east and the west regions,where the anisotropy images are more complicated,exhibiting'fossil'anisotropy and/or two-layer anisotropy.The collision between the Indian Plate and the Eurasian Plate is the main factor of upper mantle anisotropy in the western region of the Chinese mainland,while the upper mantle anisotropy in the eastern region is related to the subduction of the Pacific Plate and the Philippine Sea Plate beneath the Eurasian Plate.WANG ChunYong CHANG LiJun DING ZhiFeng LIU QiongLin LIAO WuLin Lucy M FLESCH 2014Science China Earth Sciences2014,57,1:18
11PTEN in liver diseases and cancer显示文摘The phosphoinositide 3-kinase (PI3K)/phosphatase and tensin homolog (PTEN)/Akt axis is a key signal transduction node that regulates crucial cellular functions, including insulin and other growth factors signaling, lipid and glucose metabolism, as well as cell survival and apoptosis. In this pathway, PTEN acts as a phosphoinositide phosphatase, which terminates PI3Kpropagated signaling by dephosphorylating PtdIns(3,4)P2 and PtdIns(3,4,5)P3. However, the role of PTEN does not appear to be restricted only to PI3K signaling antagonism, and new functions have been recently discovered for this protein. In addition to the well-established role of PTEN as a tumor suppressor, increasing evidence now suggests that a dysregulated PTEN expression and/or activity is also linked to the development of several hepatic pathologies. Dysregulated PTEN expression/activity is observed with obesity, insulin resistance, diabetes, hepatitis B virus/hepatitis C virus infections, and abusive alcohol consumption, whereas mutations/deletions have also been associated with the occurrence of hepatocellular carcinoma. Thus, it appears that alterations of PTEN expression and activity in hepatocytes are common and recurrent molecular events associated with liver disorders of various etiologies. These recent f indings suggest that PTEN might represent a potential common therapeutic target for a number of liver pathologies.Marion Peyrou Lucie Bourgoin Michelangelo Foti 2010World Journal of Gastroenterology2010,16,37:16

14Vascular cognitive impairment, a cardiovascular complication显示文摘Over the past two decades, the term vascular cognitive impairment(VCI) has been used to refer to a spectrum of cognitive decline characterized by executive dysfunction, associated with vascular pathology. With 30% of stroke survivors showing cognitive impairments, it is regarded as the most common cause of cognitive impairment. This is a narrative review of available literature citing sources from Pub Med, MEDLINE and Google Scholar. VCI has a high prevalence both before and after a stroke and is associated with great economic and caregiver burden. Despite this, there is no standardized diagnostic criteria for VCI. Hypertension has been identified as a risk factor for VCI and causes changes in cerebral vessel structure and function predisposing to lacuna infarcts and small vessel haemorrhages in the frontostriatal loop leading to executive dysfunction and other cognitive impairments. Current trials have shown promising results in the use of antihypertensive medications in the management of VCI and prevention of disease progression to vascular dementia. Prevention of VCI is necessary in light of the looming dementia pandemic. All patients with cardiovascular risk factors would therefore benefit from cognitive screening with screening instruments sensitive to executive dysfunction as well as prompt and adequate control of hypertension.Adiukwu Frances Ofori Sandra Ugbomah Lucy 2016World Journal of Psychiatry2016,6,2:14
15Neural EGF-like protein 1(NELL-1):Signaling crosstalk in mesenchymal stem cells and applications in regenerative medicine显示文摘Bone tissue regeneration holds the potential to solve both osteoporosis and large skeletal defects,two problems associated with significant morbidity.The differentiation of mesenchymal stem cells into the osteogenic lineage requires a specific microenvironment and certain osteogenic growth factors.Neural EGF Like-Like molecule 1(NELL-1)is a secreted glycoprotein that has proven,both in vitro and in vivo,to be a potent osteo-inductive factor.Furthermore,it has been shown to repress adipogenic differentiation and inflammation.NELL-1 can work synergistically with other osteogenic factors such as Bone Morphogenic Protein(BMP)2 and9,and has shown promise for use in tissue engineering and as a systemically administered drug for the treatment of osteoporosis.Here we provide a comprehensive up-to-date review on the molecular signaling cascade of NELL-1 in mesenchymal stem cells and potential applications in bone regenerative engineering.Mikhail Pakvasa Alex Alverdy Sami Mostafa Eric Wang Lucy Fu Alexander Li Leonardo Oliveira Aravind Athiviraham Michael J.Lee Jennifer Moriatis Wolf Tong-Chuan He Guillermo A.Ameer Russell R.Reid 2017Genes & Diseases2017,4,3:13

17卫生政策与体系研究概述显示文摘1卫生政策与体系研究的内涵 1.1定义与特点 卫生政策与体系研究(Health policy and systems research,HPSR)通常定义为“……通过提升社会组织能力来实现人群的健康目标,并研究不同社会角色对政策制定和执行的影响以及对政策成果的贡献。卫生政策与体系研究属于交叉学科,综合运用经济学、社会学、人类学、政治学、公共卫生和流行病学等学科,揭示卫生体系如何影响并适应卫生政策,以及卫生政策、健康相关因素与卫生体系之间如何相互影响”。Lucy Gilson 2013中国卫生政策研究2013,6,1:13
18TREM-1 multimerization is essential for its activation on monocytes and neutrophils显示文摘The triggering receptor expressed on myeloid cells-1(TREM-1)is a receptor expressed on innate immune cells.By promoting the amplification of inflammatory signals that are initially triggered by Toll-like receptors(TLRs),TREM-1 has been characterized as a major player in the pathophysiology of acute and chronic inflammatory diseases,such as septic shock,myocardial infarction,atherosclerosis,and inflammatory bowel diseases.However,the molecular events leading to the activation of TREM-1 in innate immune cells remain unknown.Here,we show that TREM-1 is activated by multimerization and that the levels of intracellular Ca 2+release,reactive oxygen species,and cytokine production correlate with the degree of TREM-1 aggregation.TREM-1 activation on primary human monocytes by LPS required a two-step process consisting of upregulation followed by clustering of TREM-1 at the cell surface,in contrast to primary human neutrophils,where LPS induced a rapid cell membrane reorganization of TREM-1,which confirmed that TREM-1 is regulated differently in primary human neutrophils and monocytes.In addition,we show that the ectodomain of TREM-1 is able to homooligomerize in a concentration-dependent manner,which suggests that the clustering of TREM-1 on the membrane promotes its oligomerization.We further show that the adapter protein DAP12 stabilizes TREM-1 surface expression and multimerization.TREM-1 multimerization at the cell surface is also mediated by its endogenous ligand,a conclusion supported by the ability of the TREM-1 inhibitor LR12 to limit TREM-1 multimerization.These results provide evidence for ligand-induced,receptor-mediated dimerization of TREM-1.Collectively,our findings uncover the mechanisms necessary for TREM-1 activation in monocytes and neutrophils.Kevin Carrasco Amir Boufenzer Lucie Jolly Helene Le Cordier Guanbo Wang Albert JR Heck Adelheid Cerwenka Emilie Vinolo Alexis Nazabal Alexandre Kriznik Pierre Launay Sebastien Gibot Marc Derive 2019Cellular & Molecular Immunology2019,16,5:13

20Seismic tomography of the Moon显示文摘We attempted to determine the first three-dimensional P and S wave velocity and Poisson's ratio structures of the lunar crust and mantle down to 1000 km depth under the near-side of the Moon by applying seismic tomography to the moonquake arrival-time data recorded by the Apollo seismic network operated during 1969 to 1977.Our results show that significant lateral heterogeneities may exist in the lunar interior.Because there is no plate tectonics in the Moon,the lateral heterogeneities may be produced at the early stage of the Moon formation and evolution,and they have been preserved till today.There seems to be a correlation between the distribution of deep moonquakes and lateral velocity variations in the lunar lower mantle,suggesting that the occurrence of deep moonquakes may be affected by the lunar structural heterogeneity in addition to the tidal stresses.Although this is an experimental work and the result is still preliminary,it indicates that tomographic imaging of the lunar interior is feasible.ZHAO DaPeng LEI JianShe LIU Lucy 2008Chinese Science Bulletin2008,53,24:11
