| 2 | Laser altimetry data of Chang'E-1 and the global lunar DEM model显示文摘The Laser AltiMeter (LAM), as one of the main payloads of Chang'E-1 probe, is used to measure the topography of the lunar surface. It performed the first measurement at 02:22 on November 28th, 2007. Up to December 4th 2008, the total number of measurements was approximately 9.12 million, covering the whole surface of the Moon. Using the LAM data, we constructed a global lunar Digtal Elevation Model (DEM) with 3 km spatial resolution. The model shows pronounced morphological characteristics, legible and vivid details of the lunar surface. The plane positioning accuracy of the DEM is 445 m (1σ), and the vertical accuracy is 60 m (1σ). From this DEM model, we measured the full range of the altitude difference on the lunar sur-face, which is about 19.807 km. The highest point is 10.629 km high, on a peak between crater Korolev and crater Dirichlet-Jackson at (158.656°W, 5.441°N) and the lowest point is -9.178 km in height, inside crater Antoniadi (172.413°W, 70.368°S) in the South Pole-Aitken Basin. By comparison, the DEM model of Chang'E-1 is better than the USA ULCN2005 in accuracy and resolution and is probably identical to the DEM of Japan SELENE, but the DEM of Chang'E-1 reveals a new lowest point, clearly lower than that of SELENE. | LI ChunLai1, REN Xin1, LIU JianJun1, ZOU XiaoDuan1, MU LingLi1, WANG JianYu2, SHU Rong2, ZOU YongLiao1, ZHANG HongBo1, Lü Chang1, LIU JianZhong1, ZUO Wei1, SU Yan1, WEN WeiBin1, BIAN Wei1, WANG Min1, XU Chun1, KONG DeQing1, WANG XiaoQian1, WANG Fang1, GENG Liang1, ZHANG ZhouBin1, ZHENG Lei1, ZHU XinYing1, LI JunDuo1 & OUYANG ZiYuan1 1 National Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012, China 2 Shanghai Institute of Technical Physics, Chinese Academy of Sciences, Shanghai 200083, China | 2010 | Science China Earth Sciences2010，53，11： | 19 |
| 3 | Impacts of increased atmospheric CO_2 concentration on photosynthesis and growth of micro-and macro-algae显示文摘Marine photosynthesis drives the oceanic biological CO2 pump to absorb CO2 from the atmosphere, which sinks more than one third of the industry-originated CO2 into the ocean. The increasing atmos-pheric CO2 and subsequent rise of pCO2 in seawater, which alters the carbonate system and related chemical reactions and results in lower pH and higher HCO3- concentration, affect photosynthetic CO2 fixation processes of phytoplanktonic and macroalgal species in direct and/or indirect ways. Although many unicellular and multicellular species can operate CO2-concentrating mechanisms (CCMs) to util-ize the large HCO3- pool in seawater, enriched CO2 up to several times the present atmospheric level has been shown to enhance photosynthesis and growth of both phytoplanktonic and macro-species that have less capacity of CCMs. Even for species that operate active CCMs and those whose photo-synthesis is not limited by CO2 in seawater, increased CO2 levels can down-regulate their CCMs and therefore enhance their growth under light-limiting conditions (at higher CO2 levels, less light energy is required to drive CCM). Altered physiological performances under high-CO2 conditions may cause genetic alteration in view of adaptation over long time scale. Marine algae may adapt to a high CO2 oceanic environment so that the evolved communities in future are likely to be genetically different from the contemporary communities. However, most of the previous studies have been carried out under indoor conditions without considering the acidifying effects on seawater by increased CO2 and other interacting environmental factors, and little has been documented so far to explain how physi-ology of marine primary producers performs in a high-CO2 and low-pH ocean. | WU HongYan1, ZOU DingHui1 & GAO KunShan2 1 Marine Biology Institute, Shantou University, Shantou 515063, China 2 State Key Laboratory of Marine Environmental Science, Xiamen University, Xiamen 361005, China | 2008 | Science China(Life Sciences)2008，51，12： | 18 |
| 4 | Caveolin-1 gene silencing promotes the activation of PI3K/AKT dependent on Erα36 and the transformation of MCF10A^(CE)显示文摘ERα36,a variant of estrogen receptor-α,acts as a dominant-negative factor in both estrogen-dependent and estrogen-independent transactivation signaling pathways,and is a key factor in the promotion,progression and prognosis of breast cancers.Caveolin-1,a 22-to 24-kD integral membrane protein,may function as a tumor suppressor in inhibiting of many growth-promoting signaling pathways.It was shown that downregulation of Caveolin-1 strengthens the interaction of ERα and Caveolin-1.In conclusion,Caveolin-1 gene silencing activated the PI3K/AKT signaling pathway in an ERα36-dependent way.Our finding may provide a promising therapeutic target of breast cancer. | FENG Shuang1,WANG Yang1,WANG Xi1,WANG ZhaoYi3,CUI YuYing1,LIU Jing4,ZHAO ChunHui1,JIN Mei1,2 & ZOU Wei1,2 1 College of Life Science,Liaoning Normal University,Dalian 116029,China 2 Liaoning Key Laboratory of Biotechnology and Molecular Drug R&D,Dalian 116029,China 3 Cancer Center,Creighton University,2500 California Plaza,Omaha,NE 68178,USA 4 First Clinical Hospital of Dalian Medical University,Dalian 116011,China | 2010 | Science China(Life Sciences)2010，53，5： | 16 |

| 6 | Primary scientific results of Chang'E-1 lunar mission显示文摘The strategic plan for the development of the unmanned Chinese Lunar Exploration Program is characterized by three distinct stages: 'orbiting around', 'landing on' and 'returning from' the Moon. The first Chinese lunar probe, Chang'E-1, which was successfully launched on October 24th, 2007 at Xichang Satellite Launch Center, and guided to crash on the Moon on March 1st, 2009, at 52.36°E, 1.50°S, in the north of Mare Fecunditatis, is the first step towards the 'orbiting around' stage. The Chang'E-1 mission lasted 495 days, exceeding the expected life-span by about four months. A total of 1.37 TB raw data was received from Chang'E-1. It was then processed into 4 TB scientific data products at various levels. Many scientific results have been obtained by analyzing these data, including especially the 'global lunar image from the first Chinese lunar explora- tion mission'. All scientific goals of Chang'E-1 have been achieved. It provides much useful materials for further advances of lunar sciences and planetary chemistry. Meanwhile, these results will serve as a firm basis for future Chinese lunar missions. | OUYANG ZiYuan1,2, LI ChunLai1, ZOU YongLiao1, ZHANG HongBo1, Lü Chang1, LIU JianZhong1, LIU JianJun1, ZUO Wei1, SU Yan1, WEN WeiBin1, BIAN Wei1, ZHAO BaoChang3, WANG JianYu4, YANG JianFeng3, CHANG Jin5, WANG HuanYu6, ZHANG XiaoHui7, WANG ShiJin7, WANG Min1, REN Xin1, MU LingLi1, KONG DeQing1, WANG XiaoQian1, WANG Fang1, GENG Liang1, ZHANG ZhouBin1, ZHENG Lei1, ZHU XinYing1, ZHENG YongChun1, LI JunDuo1, ZOU XiaoDuan1, XU Chun1, SHI ShuoBiao1, GAO YiFei1 & GAO GuanNan1 1 National Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012, China 2 Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China 3 Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an 710119, China 4 Shanghai Institute of Technical Physics, Chinese Academy of Sciences, Shanghai 200083, China 5 Purple Mountain Observatory, Chinese Academy of Sciences, Nanjing 210008, China 6 Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100049, China 7 Center for Space Science and Applied Research, Chinese Academy of Sciences, Beijing 100190, China | 2010 | Science China Earth Sciences2010，53，11： | 11 |
| 7 | Global absorption center map of the mafic minerals on the Moon as viewed by CE-1 IIM data显示文摘Determining the global distribution of minerals on the Moon has been an important goal of lunar science. Hyperspectral remote sensing is an important approach to acquiring minerals on the Moon on the global scale. The wavelength of the absorption band center is the key parameter for identifying minerals with reflectance spectra as well as remote sensing data. The global absorption center map of the mafic minerals of the Moon was produced for the first time with the Chang’E-1 IIM data. This map shows the global distribution of mafic minerals such as orthopyroxenes, clinopyroxenes, and olivine and even plagioclase feldspar of the Moon. The validation for some representative areas indicates that the global map is reliable and even more detailed than the results derived from Clementine-data. Moreover, our method is insensitive to the topography and viewing and illumination geometries. The global absorption band center map not only contributes to the lunar science research, but also has other implications to be further studied. Moreover, the preprocessing methods such as calibration and correction introduced in this study can be useful in other research with IIM data. | WU YunZhao 1,4* , ZHANG Xia 2 , YAN BoKun 3 , GAN FuPing 3 , TANG ZeSheng 4 , XU AoAo 4 , ZHENG YongChun 5 & ZOU YongLiao 5 1 School of Geographic and Oceanographic Sciences, Nanjing University, Nanjing 210093, China 2 Institute of Remote Sensing Applications, Chinese Academy of Sciences, Beijing 100101, China 3 Institute for Remote Sensing Method, China Aero Geophysical Survey and Remote Sensing Center for Land and Resources, Beijing 100083, China 4 Collaborative Research Laboratory on Lunar and Planetary Exploration, Macao University of Science and Technology, Taipa, Macao, China 5 National Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 11 |

| 9 | Magnetic resonance evaluation of transplanted mesenchymal stem cells after myocardial infarction in swine显示文摘Objectives To trace and evaluate intracoronary transplanted mesenchymal stem cells(MSCs) labeled with superparamagnetic iron oxide(SPIO) by using magnetic resonance imaging(MRI) in a swine model of myocardial infarction (MI).Methods MSCs were transfected with a lentiviral vector carrying the gene encoding green fluorescent protein (GFP) and labeled in vitro with SPIO.Two weeks after MI, swine were randomized to intracoronary transplantation of dual -labeled MSCs(n = 10),MSCs-GFP(n = 10) and saline(n = 5).MRI examination was performed with a 1.5T clinical scanner at 24 hours,3 weeks and 8 weeks after cells transplantation. Signal intensity(SI) changes,cardiac function and MI size were measured using MRI.Correlation between MR findings and histomorphologic findings was also investigated. Results The labeling efficiency at a combination of 25μg Fe/ml SPIO and 0.8 pi/ml Lipofectamine 2000 reached 100%.SPIO labeling did not affect GFP fluorescence and dual-labeling did not affect cell proliferation(P>0.05). Multipotentiality was not affected especially for cardiomyocyte-like cells differentiation.Cardiac cell marker of a-MHC and actinin were positively expressed by immunofluorescence staining after induction.SI on T2 * WI decreased substantial- ly in the interventricular septum 24 hours after injection of MSCs.The intensity of hypo-intense signals appeared to increase throughout the later time points.Changes in SI at 24 hours,3 weeks and 8 weeks were 52.98%±10.74%,21.53%±5.40%and 6.23%±2.01%,respectively(P<0.01).DE-MRI demonstrated both dual-labeled MSCSs and MSCs-GFP could dramatically reduce the size of MI and improve cardiac function. Histological data revealed that prussian blue stain-positive cells were found mainly in the border zone which also showed green fluorescence but negative for macrophage marker(CD68).Gross pathologic examination revealed that engrafted MSCs dramatically reduce the extent of necrotic myocardium and promote the regeneration of new,contractile myocardium along the subendocardial surface of the MI. Conclusions MSCs could be efficiently and safely labeled with SPIO and GFP,and could be detected reproducibly and noninvasively in vivo using cardiac MRI.Intracoronary transplantation of dual-labeled MSCs could increase cardiac function and reduce the size of MI. | KE Yang~1,PENG Chao-quan~1,XIANG Peng~1,ZHANG Cheng-xi~1, ZOU Li-yuan~1,WU Xiao~1,YA Gao~1,KANG Z huang~2,HE Ke-ke~2,LIU Jin-lai~1 (1.Department of Cardiology,The Third Affiliated Hospital, Sun Yat-sen University,Guangzhou 2.Department of Radiology, the Third Affiliated Hospital,Sun Yat-sen University, Guangzhou 5100630 3.Center for Stem Cell Biology and Tissue Engineering,Sun Yat-sen University,Guangzhou 5100120) | 2011 | 岭南心血管病杂志2011，17，S1： | 7 |

| 12 | Identification of marine natural gases with different origin sources显示文摘Kinetic experiments of gas generation for typical samples of marine gas precursors including low-maturity kerogen,residual kerogen and oil as well as dispersed liquid hydrocarbon(DLH)in source rocks were performed by closed system,and the evolution trends of molecular and isotopic compositions of natural gases from different precursors against the maturity(R0%)at laboratory conditions were analyzed.Several diagrams of gas origin were calibrated by using the experimental data.A diagram based on the ratio of normal and isomerous butane and pentane(i/nC4-i/nC5)was proposed and used to identify the origins of the typical marine natural gases in the Sichuan Basin and the Tarim Basin, China.And the maturities of natural gases were estimated by using the statistical relationships between the gaseous molecular carbon isotopic data and maturities(δ13C-R 0 %)with different origins.The results indicate that the molecular and isotopic compositions of simulated gases from different precursors are different from each other.For example,the dryness index of the oil-cracking gas is the lowest;the dryness indices of gases from DLH and kerogen in closed system are almost the same;and the dryness index of gases from residual kerogen is extremely high,indicating that the kerogen gases are very dry;the contents of non-hydrocarbon gases in kerogen-cracking gases are far higher than those in oil-cracking and DLH-cracking gases.The molecular carbon isotopes of oil-cracking gases are the lightest,those of kerogen in closed system and GLH-cracking gases are the second lightest,and those of cracking gases from residual kerogen are the heaviest.The calibration results indicate that the diagrams of ln(C1/C2)-ln(C2/C3)andδ13C2-δ13C3-ln(C2/C3)can discriminate primary and secondary cracking gases,but cannot be used to identify gas origin sources,while the diagram of i/nC4-i/nC5 can differentiate the gases from different precursors.The application results of these diagrams show that gas mixtures extensively exist in China,which involved the gases from multiple precursors and those from different maturity stages.For example,marine gases in the Sichuan Basin involve the mixture of oil-cracking gases and high-over-maturated kerogen gases,while those in the Tarim Basin involve not only the mixture of gases from multiple precursors,but also those from different maturity gases and post-reservoir alternations such as oxidized degradation and gas intrusion processes. | WANG YunPeng 1 ,ZHAO ChangYi 2 ,WANG ZhaoYun 2 ,WANG HongJun 2 ,TIAN Jin 1 ,ZOU YanRong 1 &LIU JinZhong1 1State Key Laboratory of Organic Geochemistry,Guangzhou Institute of Geochemistry,Chinese Academy of Sciences,Guangzhou 510640,China 2Institute of Geology,Research Institute of Petroleum Exploration and Development,PetroChina,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S1： | 4 |
| 13 | Relationship between surface subsidence factor and mining depth of strip pillar mining显示文摘Strip pillar mining is one of the most important technical measures to control mining subsidence in China. Mining depth is one of the most important factors that can affect the mining subsidence in strip pillar mining. Six numerical simulation models were set up to simulate the surface subsidence of strip pillar mining in different mining depths. The mining depth in these six models ranges from 300 to 800 m. The simulated results were compared and analyzed. The formula was established based on the simulated results. It demonstrated that the subsidence of strip pillar mining method is related to mining depth. While the other conditions are the same, the subsidence of strip pillar mining increases with the increase of mining depth by logarithmic relationship. | GUO Wen-bing1, 2, HOU Quan-lin 1, ZOU You-feng2 1.

| 15 | Polymorphisms in the 5 ′ regulatory region of my-ostatin gene are associated with early growth traits in Yorkshire pigs显示文摘Myostatin is a negative regulator of skeletal muscle mass. The present study cloned the 5′ regulatory region of porcine myostatin gene, screened its polymorphisms and analyzed their associations with early growth traits in Yorkshire pigs. The results indicated that a fragment length polymorphism and a polymorphism concerning two nucleotide changes exist in the 5′ regulatory region of porcine my-ostatin gene. At sites 435 and 447, allele A and allele B have the haplotypes of A-G and G-A, respec-tively. The allelic frequency of B is 0.475 in Yorkshire pigs. No homozygous BB genotype was detected in 9 Laiwu Black pigs. Allele B was found to have positive effect on body weight on day 21 (BW21) (P<0.01), body weight on day 28 (BW28) (P<0.05), body weight on day 70 (BW70) (P<0.05), average daily gain from birth to 21 d (ADG1) (P<0.01), average daily gain from birth to 28 d (ADG2) (P<0.05) and av-erage daily gain from 21 d to 70 d (ADG3) (P<0.01), respectively. The additive effect of allele B on BW21, BW28, BW70, ADG1, ADG2 and ADG3 was 0.596±0.205 kg (P=0.0041), 0.498±0.200 kg (P=0.0136), 1.409±0.551 kg (P=0.0112), 28.39±9.74 g P=0.0041), 17.78±7.15 g (P=0.0136) and 37.00±16.92 g (P=0.0304), respectively, whereas its effect on average daily gain from 28 d to 70 d (ADG4) was not significant (P>0.1), although BB individuals are superior in average daily gain to AA and AB. | YU LingZhi1, TANG Hui1, WANG JiYing2, WU Ying2, ZOU LiLi1, JIANG YunLiang1, WU ChangXin3 & LI Ning4 1 College of Animal Science and Veterinary Medicine, Shandong Agricultural University, Taian 271018, China 2 Institute of Animal Science and Veterinary Medicine, Shandong Academy of Agricultural Sciences, Jinan 250100, China 3 College of Animal Science and Technology, China Agricultural University, Beijing 100094, China 4 State Key Laboratory for Agro-biotechnology, China Agricultural University, Beijing 100094, China. | 2007 | Science China(Life Sciences)2007，50，5： | 3 |

| 20 | Triaxial ellipsoid models of the Moon based on the laser altimetry data of Chang'E-1显示文摘Lunar geodetic parameters, which play an important role in lunar exploration, can be calculated from the gravity and topography data. With the CE-1 altimetry data and LP gravity model, we calculate such geodetic parameters as the principle moment of inertia, the principle inertia axes, equatorial radius, polar radius, mean radius, flattening and offset between center of mass and center of figure (DCOM-COF). According to the CE-1 altimetry data and the above geodetic parameters, a tri-axial ellipsoid (CE-1-LAM-GEO) and a tri-axial level ellipsoid (CE-1-LAM-LEVEL) are calculated individually, providing mass center and figure center offset (DCOM-COF) and parameters more reliable in direction and magnitude. | WANG WenRui1,2,3, LI Fei1, LIU JianJun1, REN Xin2, ZOU XiaoDuan2,3, MU LingLi2, YAN JianGuo1, ZOU YongLiao2, ZHANG HongBo2, Lü Chang2, LIU JianZhong2, ZUO Wei2, SU Yan2, WEN WeiBin2, BIAN Wei2, WANG Min2, LI ChunLai2 & OUYANG ZiYuan2 1 School of Geodesy and Geomatics, Wuhan University, Wuhan 430079, China 2 National Astronomical Observatory of Chinese Academy of Sciences, Beijing 100012, China 3 Graduate School of Chinese Academy of Sciences, Beijing 100049, China | 2010 | Science China Earth Sciences2010，53，11： | 2 |
