1Identification and expansion of cancer stem cells in tumor tissues and peripheral blood derived from gastric adenocarcinoma patients显示文摘胃的癌症是世界范围的第四很普通的癌症,与死亡的高率和低 5 年的幸存率。迄今为止,有为胃的癌症的有效治疗学的协议的缺乏。最近的研究建议癌症干细胞(CSC ) 为肿瘤开始,侵略,转移,和抵抗负责到 anticancer 治疗。因此,指向胃的 CSC 的治疗是吸引人的。然而,在人的胃的腺癌(GAC ) 的 CSC 没被描述。这里,我们从 GAC 病人在肿瘤纸巾和外部血识别 CSC。从肿瘤纸巾和病人的外部血被孤立的人的 GAC (GCSC ) 的 CSC 带了 CD44 和 CD54 表面标记,当注入了 immunodeficient 老鼠时,高度类似于原来的人的肿瘤的产生肿瘤,在 vitro 区分了进胃的上皮的房间,并且在 vivo 并且在 vitro 自我更新。我们的调查结果建议有效治疗学的协议必须指向 GCSC。从 GAC 病人的循环的 GCSC 的俘获也为为肿瘤转移潜在地负责的一张批评房间人口的鉴定显示出大潜力,并且为早诊断并且胃的癌症的纵的监视提供一个有效协议。Tie Chen Kun Yang Jianhua Yu Wentong Meng Dandan Yuan Feng Bi Fang Liu Jie Liu Bing Dai Xinzu Chen Fang Wang Fan Zeng Hong Xu Jiankun Hu Xianming Mo 2012Cell Research2012,22,1:50
2Sample maturation calculated using Raman spectroscopic parameters for solid organics: Methodology and geological applications显示文摘The shape and shift of Raman peak of solid organics prove to be capable of revealing atomic and molecular level vibration information of aromatic ring structure and its relationship with sample maturation. Raman 'D' peaks and 'G' peaks of a series of continuously maturated coal samples were measured, and the inter-peak intervals (G-D) and peak height ratios (Dh/Gh) were derived and correlated with the vitrinite reflectance (vRo%) of standard coal samples. As a result, two formulae were established by using the two Raman indices for calculation of Raman reflectance (RmcRo%), which is equivalent to vitrinite reflectance. The formula for calculating Raman reflectance indicative of organic maturation using Raman shift inter-peak interval (G-D) is RmcRo%=0.0537d(G-D)-11.21, which is mainly applicable to matured to highly matured carbonized samples of solid organics; The formula for calculating Raman reflectance indicative of organic maturation using Raman peak height ratio (Dh/Gh) is RmcRo%=1.1659h (Dh/Gh)+2.7588, which is mainly applicable to carbonized samples of solid organics that are over matured or going to be turned into granulated graphite. Preliminary applications indicate that Raman reflectance 'RmcRo%' calculated based on results of Raman spectral analysis of solid organics can be used to characterize sample maturation at molecular level, so enjoying extensive prospects in geological applications.LIU DeHan XIAO XianMing TIAN Hui MIN YuShun ZHOU Qin CHENG Peng SHEN JiaGui 2013Chinese Science Bulletin2013,58,11:30
3Seafloor hydrothermal activity and polymetallic sulfide exploration on the southwest Indian ridge显示文摘Polymetallic sulfides have attracted more attentions,which are regarded as one of the potential seabed mineral resources for their high grade of precious metal elements such as Cu,Zn,Pb,Au,and Ag.Since2007,there are four China dayang cruises(CDCs)with eight legs totally,which have been carried out to investigate polymetallic sulfides on the southwest Indian ridge(SWIR),and eight hydrothermal vents have been found.In2011,the China Ocean Mineral Resources Research and Development Association(COMRA)and International Seabed Authority(ISA)signed a 15-year contract for exploration for polymetallic sulfides located on the SWIR between 46°S and 53°S.The area allocated to the COMRA is approximately 10,000 km2.In this paper,we review the recent research advances about hydrothermal activity of the SWIR by the CDCs.As for the sulfides exploration in the future,some aspects should be emphasized,such as the controlling factors of sulfide mineralization on the SWIR,prospecting methods of inactive and buried sulfide deposits,sulfides resources assessment method,and the nearbottom sulfides exploration technology systems.Chunhui Tao Huaiming Li Xiaobing Jin Jianping Zhou Tao Wu Yonghua He Xianming Deng Chunhua Gu Guoyin Zhang Weiyong Liu 2014Chinese Science Bulletin2014,59,19:25
4Origin of natural sulphur-bearing immiscible inclusions and H_2S in oolite gas reservoir, Eastern Sichuan显示文摘Based on results of microscopic observation and laser Raman analysis about fluid in- clusions, multiple special forms of immiscible inclusions that contain sulphur, liquid hydrocarbon, bi- tumen, etc. were discovered in samples collected from the H2S gas reservoir-containing carbonates in the Lower Triassic Feixianguan Formation in the Jinzhu-Luojia area, Kai County, Sichuan Province. Based on the lithology and burial history of the strata involved as well as measurement results of homogenization temperature of fluid inclusions, bitumen reflectivity, etc., it is concluded that the H2S in the gas reservoir resulted from the thermal reaction between hydrocarbons in reservoir and CaSO4 in the gypsum-bearing dolostone section at the high temperature (140℃―170℃) oil-cracked gas for- mation stage in Late Cretaceous. Thereafter, research on a great number of immiscible inclusions in the reservoir reveals that elemental sulphur resulted from oxidation of part of the earlier-formed H2S and further reaction between sulphates, hydrocarbons and H2S in geological fluids in H2S-bearing gas reservoir at a temperature of 86℃―89℃ and a pressure of 340×105Pa and during the regional uplift stage as characterized by temperature decrease and pressure decrease in Tertiary. Meanwhile, gyp- sum, anhydrite and calcite formed at this stage would trap particles like elemental sulphur and result in a variety of special forms of immiscible inclusions, and these inclusions would contain information concerning the complexity of the fluids in the reservoir and the origin of H2S and natural sulphur in the gas reservoir.LIU Dehan XIAO Xianming XIONG Yongqiang GENG Ansong TIAN Hui PENG Ping'an SHEN Jiagui WANG Yunpeng 2006Science China Earth Sciences2006,49,3:10
5High density methane inclusions in Puguang Gasfield:Discovery and a T-P genetic study显示文摘Based on measurement of homogenization temperature of inclusions and Raman spectral analysis, high density methane inclusions were discovered in the Triassic reservoirs of Puguang Gasfield. The methane inclusions show a homogenization temperature Th = -117.5― -118.1℃, a corresponding density of 0.3455―0.3477 g/cm3, and a Raman scatter peak v1 shift varying between 2911―2910 cm-1, which signifies a very high density of methane inclusions. The salt water inclusions paragenetic with methane inclusions show a homogenization temperature Th=170―180℃. Based on the composition of methane inclusions as determined by Raman spectra, PVTsim software was used to simulate the trapping pressure for high density methane inclusions in geologic history, and the trapping pressure was found to be as high as 153―160 MPa. Even though Puguang Gasfield is currently a gas pool of normal pressure, and the fluid pressure for the gas pool ranges between 56―65 MPa. However, data from this study indicates that remarkable overpressure may be generated at the stage of mass production of gas cracked from oils in Cretaceous, as high density methane inclusions constitute key evidence for overpressure in gas pool in geologic history. Meanwhile, discovery of small amounts of H2S, CO2 or heavy hydrocarbon in part of the high density methane inclusions indicates that the geochemical environment for trapping of inclusions may be related to formation of H2S. Therefore, the observation results can help to explore the thermochemical sulfate reduction (TSR) conditions for oil cracking and H2S formation.LIU Delian DAI JinXing XIAO XianMing TIAN Hui YANG Chun HU AnPing MI JingKui SONG ZhiGuang 2009Chinese Science Bulletin2009,54,24:8
6Effect of Liuweidihuang pill and Jinkuishenqi pill on inhibition of spontaneous breast carcinoma growth in mice显示文摘OBJECTIVE: To investigate the preventing and treating action of Liuweidihuang pill(LP) and Jinkuishenqi pill(JP) on spontaneous breast carcinoma in mice.METHODS: A model of spontaneous breast carcinoma was derived from 11.5-month-old female Kunming breeding mice following the delivery of several litters. The mice were randomly divided into five groups: model control group(C),Liuweidihuang pill high-dose group(LH; 4.6 g·kg1·d1),Liuweidihuang pill low-dose group(LL;2.3 g·kg1·d﹣1),Jinkuishenqi pill high-dose group(JH; 4.6 g·kg﹣1·d1) and Jinkuishenqi pill low-dose group(JL;2.3 g·kg﹣1·d﹣1). Cancer tissue volume was measured by water immersion. Histopathology was analyzed by hematoxylin and eosin staining. Vascular endothelial growth factor(VEGF),extracellular signal-regulated kinase(ERK) and cyclin D1 protein expression in cancer tissue was assayed by western blotting.RESULTS: Compared with the control group,cancer tissue volume and weight were lower in the LP and JP groups,and survival time was longer. The expression of VEGF,ERK and Cyclin D1 were inhibited in the LP and JP groups(P < 0.05),and cell differentiation was increased. Tumor weights and volumes and VEGF,ERK and Cyclin D1 expression in LL or LH were significantly lower than in JL and JH(P < 0.01).CONCLUSION: Both LP and JP could restrain cancer growth and promote cancer cell differentiation;moreover,LP was more effective than JP The likely mechanism of action was via inhibition of VEGF,ERK and cyclin D1.Zheng Lixiang Liu Hongning Gong Yan Meng Xianming Jiang Runde Wang Xiaomin Wang Qiaofeng Wang Yue 2015Journal of Traditional Chinese Medicine2015,35,4:8
7Dating formation of natural gas pools using fluid inclusion data from reservoirs显示文摘A method has been suggested which is based on the homogenization temperatures and other data of fluid inclusions from a reservoir rock, with the combination of burial and geothermal history of the hosted rock, to date the gas reservoir formation. On the basis of this, a case study of the Carboniferous-Permian gas pools in the Ordos Basin has been conducted. The results have shown that the reservoir sandstones of the gas pool were filled by gases during 125-150 Ma, earlier in the southern area and later in the northern area, which is consistent with the basin’s geological and geochemical background under which the gas pools formed.Xianming Xiao Zufa Liu Jiaku Mi Dehan Liu Jiagui Shen Zhiguang Song 2002Chinese Science Bulletin2002,47,18:6
8The generation and accumulation of natural gas from Yinan 2 gas pool in Kuqa Depression显示文摘By using the methods of hydrocarbon generation kinetics and carbon isotope kinetics, combined with geological background of natural gas pool formation, the generation and accumulation of natural gas from Yinan 2 gas pool was studied in Kuqa Depression of the Tarim Basin. Natural gas of Yinan 2 gas pool is mainly derived from Middle and Lower Jurassic coal-bearing source rocks, and generally belongs to long time-accumulated gas. It is suggested that Yinan 2 gas is chiefly accumulated in the last 5 Ma, its Ro ranges from 1.25% to 1.95%, and the loss rate of natural gas is about 25%-30%. This work not only complements and reduces the deficiency of formation model of natural gas pools which traditionally depends on the matching relationships between source rock, reservoir, cap rock, and trap, but also is a useful reference in the study of other gas pools.LI Xianqing XIAO Xianming TANG Yongchun XIAO Zhongyao Ml Jingkui LIU Dehan SHEN Jiagui LIU Jinzhong 2004Chinese Science Bulletin2004,49,S1:6
9A new method to reconstruct hydrocarbon-generating histories of source rocks in a petroleum-bearing basin——the method of geological and geochemical sections显示文摘Via investigating typical Palaeozoic and Mesozoic petroleum-bearing basins in China by using thermal maturation theories of organic matter to improve the conventional Karweil’s method, a new method to reconstruct hydrocarbon-generating histories of source rocks has been suggested. This method, combining geological background with geochemical information makes the calculated VRo closer to the measured one. Moreover, it enables us to make clear the hydrocarbon generation trend of source rocks during geological history. The method has the merits of simple calculation and objective presentation, especially suitable to basins whose sedimentation and tectonic movements are complicated.XIAO Xianming LIU Zufa LIU Dehan SHEN Jiagui FU Jiamo 2000Chinese Science Bulletin2000,45,S1:6
10Observation of hydrocarbon generation and migration of highly-matured carbonates by means of laser-induced fluorescence microscopy显示文摘Some important information on hydrocarbon generation, inclusion and migration inhighly-matured carbonates of lower Palaeozoic age from the Ordos Basin and Tarim Basin has been analyzed by a newly-combined laser-induced fluorescence microscope (LFM) designed by our laboratory. The following information has been obtained from the lower Ordovician lamellar carbonates with equivalent vitrinite reflectance (Ro) as high as 1.6%-1.7% and residual TOC of 0.14%-0.35% from the Ordos Basin: wide occurrences of oil and source macerals with strong fluorescence, including G.Prisca alginite, lamalginite, telalginite and algae-detrinite; fluorescing asphalt among mineral crystals; some groundmass and spheroid-like reservoir bitumen with high maturation levels in the pores of dolomites. Various kinds of fluorescing organic inclusions and asphalt have been found in the carbonates, calcareous shales and silt-shales with high maturation levels from the Cambrian-Ordovician strata in the Tarim Basin.

15Vertical coherency function model of spatial ground motion显示文摘Many studies have focused on horizontal ground motion, resulting in many coherency functions for horizontal ground motion while neglecting related problems arising from vertical ground motion. However, seismic events have demonstrated that the vertical components of ground motion sometimes govern the ultimate failure of structures. In this paper, a vertical coherency function model of spatial ground motion is proposed based on the Hao model and SMART 1 array records, and the validity of the model is demonstrated. The vertical coherency function model of spatial ground motion is also compared with the horizontal coherency function model, indicating that neither model exhibits isotropic characteristics. The value of the vertical coherency function has little correlation with that of the horizontal coherency function. However, the coherence of the vertical ground motion between a pair of stations decreases with their projection distance and the frequency of the ground motion. When the projection distance in the wave direction is greater than 800 meters, the coherency between the two points can be neglected.Ye Jihong Pan Jinlong Liu Xianming 2011Earthquake Engineering and Engineering Vibration2011,10,3:5

17Co-implantation of magnesium and zinc ions into titanium regulates the behaviors of human gingival fibroblasts显示文摘Soft tissue sealing around implants acts as a barrier between the alveolar bone and oral environment,protecting implants from the invasion of bacteria or external stimuli.In this work,magnesium(Mg)and zinc(Zn)are introduced into titanium by plasma immersed ion implantation technology,and their effects on the behaviors of human gingival fibroblasts(HGFs)as well as the underlying mechanisms are investigated.Surface characterization confirms Mg and Zn exist on the surface in metallic and oxidized states.Contact angle test suggests that surface wettability of titanium changes after ion implantation and thus influences protein adsorption of surfaces.In vitro studies disclose that HGFs on Mg ion-implanted samples exhibit better adhesion and migration while cells on Zn ion-implanted samples have higher proliferation rate and amounts.The results of immunofluorescence staining and real-time reverse-transcriptase polymerase chain reaction(RT-PCR)suggest that Mg mainly regulates the motility and adhesion of HGFs through activating the MAPK signal pathway whereas Zn influences HGFs proliferation by triggering the TGF-βsignal pathway.The synergistic effect of Mg and Zn ions ensure that HGFs cultured on co-implanted samples possessed both high proliferation rate and motility,which are critical to soft tissue sealing of implants.Lanyu Wang Qiming Luo Xianming Zhang Jiajun Qiu Shi Qian Xuanyong Liu 2021Bioactive Materials2021,6,1:4

19The role of pathological tau in synaptic dysfunction in Alzheimer’s diseases显示文摘Alzheimer's disease(AD)is a neurodegenerative disease characterized by progressive cognitive decline,accompanied by amyloid-β(Aβ)overload and hyperphosphorylated tau accumulation in the brain.Synaptic dysfunction,an important pathological hallmark in AD;is recognized as the main cause of the cognitive impairments.Accumulating evidence suggests that synaptic dysfunction could be an early pathological event in AD.Pathological tau,which is detached from axonal microtubules and mislocalized into pre-and postsynaptic neuronal compartments,is suggested to induce synaptic dysfunction in several ways,including reducing mobility and release of presynaptic vesicles,decreasing glutamatergic receptors,impairing the maturation of dendritic spines at postsynaptic terminals,disrupting mitochondrial transport and function in synapses,and promoting the phagocytosis of synapses by microglia.Here,we review the current understanding of how pathological tau mediates synaptic dysfunction and contributes to cognitive decline in AD.We propose that elucidating the mechanism by which pathological tau impairs synaptic function is essential for exploring novel therapeutic strategies for AD.Moxin Wu Manqing Zhang Xiaoping Yin Kai Chen Zhijian Hu Qin Zhou Xianming Cao Zhiying Chen Dan Liu 2021Translational Neurodegeneration2021,10,4:4
