| 1 | Quantitatively distinguishing sediments from the Yangtze River and the Yellow River using δEu_N-ΣREEs plot显示文摘Sediment samples were collected from the lower channel of the Yangtze River and the Yellow River and the contents of rare earth elements (REEs) were measured. In addition, some historical REEs data were collected from published literatures. Based on the δEuN-ΣREEs plot, a clear boundary was found be-tween the sediments from the two rivers. The boundary can be described as an orthogonal polynomial equation by ordinary linear regression with sediments from the Yangtze River located above the curve and sediments from the Yellow River located below the curve. To validate this method, the REEs con-tents of sediments collected from the estuaries of the Yangtze River and the Yellow River were meas-ured. In addition, the REEs data of sediment Core 255 from the Yangtze River and Core YA01 from the Yellow River were collected. Results show that the samples from the Yangtze River estuary and Core 255 almost are above the curve and most samples from the Yellow River estuary and Core YA01 are below the curve in the δEuN-ΣREEs plot. The plot and the regression equation can be used to distin-guish sediments from the Yangtze River and the Yellow River intuitively and quantitatively, and to trace the sediment provenance of the eastern seas of China. The difference between the sediments from two rivers in the δEuN-ΣREEs plot is caused by different mineral compositions and regional climate patterns of the source areas. The relationship between δEuN and ΣREEs is changed little during the transport from the source area to the river, and from river to the sea. Thus the original information on mineral compositions and climate of the source area was preserved. | JIANG FuQing ZHOU XiaoJing LI AnChun LI TieGang | 2009 | Science China Earth Sciences2009，52，2： | 14 |
| 2 | Geochemical character and material source of sediments in the eastern Philippine Sea显示文摘Based upon analyses of grain-size, rare earth element (REE) compositions, elemental occurrence phases of REE, and U-series isotopic dating, the sediment characteristics and material sources of the study area were examined for the recently formed deep-sea clays in the eastern Philippine Sea. The analytical results are summarized as follows. (1) Low accumulation rate, poor sorting and roundness, and high contents of grains coarser than fine silt indicate relatively low sediment input, with localized material source without long distance transport. (2) The REE Contents are relatively high. Shale-normalized patterns of REE indicate weak enrichment in heavy REE (HREE), Ce-passive anomaly, and Eu-positive anomaly. (3) Elemental occurrence phases of REE between the sediments with and without crust are similar. REE mainly concentrate in residual phase and then in ferromanganese oxide phase. The light REE (LREE) enrichment, Ce-positive anomaly, and Eu-positive anomaly occur in re- sidual phase. Ferromanganese oxide phase shows the characteristics of relatively high HREE content and Ce-passive anomaly. (4) There are differences in each above mentioned aspect between the sedi- ments with and without ferromanganese crust. (5) Synthesizing the above characteristics and source discriminant analysis, the study sediments are deduced to mainly result from the alteration of local and nearby volcanic materials. Continental materials transported by wind and/or river (ocean) flows also have minor contributions. | XU ZhaoKai LI AnChun JlANG FuQing XU FangJian | 2008 | Chinese Science Bulletin2008，53，6： | 14 |
| 3 | Preservation of black carbon in the shelf sediments of the East China Sea显示文摘Concentrations and carbon isotopic(14C,13C) compositions of black carbon(BC) were measured for three sediment cores collected from the Changjiang River estuary and the shelf of the East China Sea. BC concentrations ranged from 0.02 to 0.14 mg/g(dry weight) ,and accounted for 5% to 26% of the sedimentary total organic carbon(TOC) pool. Among the three sediment cores collected at each site,sediment from the Changjiang River estuary had relatively high BC contents compared with the sedi-ments from the East China Sea shelf,suggesting that the Changjiang River discharge played an im-portant role in the delivery of BC to the coastal region. Radiocarbon measurements indicate that the ages of BC are in the range of 6910 to 12250 years old B.P.(before present) ,that is in general,3700 to 9000 years older than the 14C ages of TOC in the sediments. These variable radiocarbon ages suggest that the BC preserved in the sediments was derived from the products of both biomass fire and fossil fuel combustion,as well as from ancient rock weathering. Based on an isotopic mass balance model,we calculated that fossil fuel combustion contributed most(60%―80%) of the BC preserved in these sediments and varied with depth and locations. The deposition and burial of this 'slow-cycling' BC in the sediments of the East China Sea shelf represent a significant pool of carbon sink and could greatly influence carbon cycling in the region. | WANG XuChen LI AnChun | 2007 | Chinese Science Bulletin2007，52，22： | 11 |
| 4 | Sediment provenance and evolution of the East Asian winter monsoon since 700 ka recorded by major elements in the West Philippine Sea显示文摘To synthetically realize the character of major-element compositions as well as its significance for provenance and paleoenvironment recorded in core sediments of the West Philippine Sea over the last 700 ka,grain size and major elements of 221 bulk sediments,together with major-element compositions in the detrital phase of 16 typical samples,in core MD06-3047 collected from the Benham Rise were analyzed.Both discrimination plot and R-mode factor analysis indicate that vertical changes of major elements are mainly controlled by the sedimentation of nearby volcanic matter and the eolian dust input,whereas influences from marine biologic deposition and hydrothermal activity are minor.In particular,Al2O3 and K2O are representative of an eolian dust factor.The variation in the eolian dust factor score is characterized by the obviously glacial-interglacial periodicity and can be well compared with the paleotemperature record of the Antarctic ice core and the evolution of the East Asian winter monsoon(EAWM) recorded in the Chinese loess sequence,and then offers a new proxy for the evolution history of eolian dust input into the study area that is controlled by the EAWM intensity and aridity in the continental source regions of atmospheric dust. | XU ZhaoKai LI TieGang YU XinKe LI AnChun TANG Zheng CHOI JinYong NAN QingYun | 2013 | Chinese Science Bulletin2013，58，9： | 7 |
| 5 | Sedimentation rates and provenance analysis in the Southwestern Okinawa Trough since the mid-Holocene显示文摘As a high-sedimentation rate depocenter along the path of the Kuroshio Current, the southwesternmost part of the Okinawa Trough is a key area to understand the Kuroshio history and sediments transpor-tation. A 34.17-m-long sediment core was obtained by the advanced piston corer of Marco Polo/IMAGES XII MARION DUFRESNE during the May 2005 from the Southern Okinawa Trough at site MD05-2908. The recovered sediments were analyzed by AMS 14C dating, coarse size fraction (>63 μm) extraction and moisture content determination in order to study its sedimentation flux and provenance. The depth-age relationship of core MD05-2908 was well constrained by 17 14C dating points. The sediments span across the mid-Holocene (6.8 ka B.P.) and have remarkablely high sedimentation rates between 1.8 and 21.2 m ka?1, which is well consistent with the modern observations from sediment traps. We identified five 70―200 a periods of abnormally rapid sedimentation events at 6790―6600 a B.P., 5690―5600 a B.P., 4820―4720 a B.P., 1090―880 a B.P., and 260―190 a B.P., during which the highest sedimentation rate is up to 21.2 m/ka. In general, the lithology of the sediments were dominated by silt and clay, associated with less than 5% coarse size fraction (>63 μm). As the most significant sediment source, the Lanyang River in northeastern Taiwan annually deliver about 10Mt materials to the coastal and offshore region of northeast Taiwan, a portion of which could be carried northward by currents toward the study area. Therefore, we concluded that the 5 abnormally rapid sedimentation events may be related to intensified rainfall in Taiwan and thus increased materials to our study area at that time. However, a few extreme-rapid sedimentation events cannot be explained by normal river runoff alone. The large earth-quakes or typhoons induced hyperpycnal discharge of fluvial sediment to the ocean may also act as a potential source supply to the Okinawa Trough. | LI ChuanShun JIANG Bo LI AnChun LI TieGang JIANG FuQing | 2009 | Chinese Science Bulletin2009，54，7： | 7 |
| 6 | BIX-01294-enhanced chemosensitivity in nasopharyngeal carcinoma depends on autophagy-induced pyroptosis显示文摘Nasopharyngeal carcinoma(NPC)is a common cancer in southern China and Southeast Asia.Nowadays,radiotherapy is the therapy of choice for NPC patients,and chemotherapy has been found as an alternative treatment for advanced NPC patients.However,finding novel drugs and pharmacologically therapeutic targets for NPC patients is still urgent and beneficial.Our study showed that BIX-01294(BIX)can induce autophagic vacuoles formation and conversion of LC3B-I to LC3B-II in NPC cells in both dose-and time-dependent manners.Notably,the combination of BIX and chemotherapeutic drugs significantly decreased the cell viability and increased the lactate dehydrogenase release.Meanwhile,BIX plus cis-platinum(Cis)treatment induced pyroptosis in NPC cells as featured by cell swelling and bubble blowing from the plasma membrane,the increased frequency of annexin V and propidium iodide(PI)double-positive cells,as well as the cleavage of gasdermin E(GSDME)and caspase-3.Moreover,the deficiency of GSDME completely shifted pyroptosis to apoptosis.Furthermore,the inhibition of autophagy by chloroquine and the knockout of ATG5 gene significantly blocked the BIX-induced autophagy as well as pyroptosis in both in vitro and in vivo studies.Our data demonstrated that BIX-combined chemotherapeutic drugs could induce the Bax/caspase-3/GSDME-mediated pyroptosis through the activation of autophagy to enhance the chemosensitivity in NPC. | Qian Li Min Wang Yan Zhang Liuqian Wang Wei Yu Xiaomin Bao Biyun Zhang Yanghong Xiang Anchun Deng | 2020 | Acta Biochimica et Biophysica Sinica2020，52，10： | 5 |
| 7 | Paleoenvironment evolution of the East Philippine Sea recorded in the new-type ferromanganese crust since the terminal Late Miocene显示文摘From systemic research of microstructure, geochemistry, uranium-series and 10Be isotope dating on a new-type deepwater ferromanganese crust from the East Philippine Sea, the paleoenvironment evolu-tion of the target area since the terminal Late Miocene was recovered. The vertical section changes of microstructure and chemical composition are consistent in the studied crust, which indicate three major accretion periods and corresponding paleoenvironment evolution of the crust. The bottom crust zone was formed in the terminal Late Miocene (5.6 Ma) with loose microstructure, high detritus content and high growth rate. Reductions of mineral element content, accretion rate and positive Ce-anomaly degree at 4.6 Ma indicate temporal warming, which went against the crust accretion and finally formed an accretion gap in the terminal Middle Pliocene (2.8―2.7 Ma). The more active Antarctic bottom sea-waters in the Late Pliocene (2.7 Ma) facilitated the fast transfer to the top pure crust zone. Hereafter, with the further apart of volcanic source and the keeping increase of eolian material (1.0 Ma), although surrounding conditions were still favorable, mineral element content still shows an obvious reducing trend. It thereby offers new carrier and data for the unclear paleoceanographic research of the target area since the terminal Late Miocene. | XU ZhaoKai LI AnChun JIANG FuQing LI TieGang MENG QingYong JIN Ning | 2007 | Science China Earth Sciences2007，50，8： | 4 |
| 8 | Host cell apoptosis induced by infection with duck swollen head hemorrhagic disease virus显示文摘This study aimed to examine the host cell apoptosis in the tissues of Peking ducks infected with duck swollen head hemorrhagic disease virus(DSHDV).The dynamic changes associated with apoptosis occurring in the internal tissues were evaluated at different time points postinoculation(PI) by performing hematoxylin and eosin(HE) staining,followed by light microscopy,terminal deoxynucleotidyl transferase dUTP nick-end labeling(TUNEL) assay,and transmission electron microscopy(TEM).The results showed that DSHDV infection could induce apoptosis in host cells,including those of the bursa of Fabricius(BF),thymus,spleen,liver,intestinal tract,kidney,and esophagus.The apoptotic index(AI) values increased with time from 2 to 72 h PI,and the highest values were recorded at 72 h PI.Further,cell death due to classic necrosis was observed in the dying or deceased ducks after 72 h PI.In conclusion,host cell apoptosis can be induced by DSHDV and may play an important role in the pathogenesis of duck viral swollen head hemorrhagic disease(DVSHD). | Chuanfeng Li Anchun Cheng Mingshu Wang Chanjuan Shen Na Zhang Yi Zhou Dekang Zhu Qihui Luo Renyong Jia Xiaoyue Chen | 2009 | Progress in Natural Science:Materials International2009，19，1： | 3 |
| 9 | Enhanced weathering input from South Asia to the Indian Ocean since the late Eocene显示文摘nhanced silicate weathering induced by the uplift of the Himalayan-Tibetan Plateau(HTP)has been considered as the major cause of pCO_(2) decline and Cenozoic cooling.However,this hypothesis remains to be validated,largely due to the lack of a reliable reconstruction of the HTP weathering flux.Here,we present a 37-million-year record of the difference in the seawater radiogenic neodymium isotopic composition(△ε_(Nd))of Ocean Drilling Program(ODP)sites and Fe-Mn crusts between the northern and central Indian Ocean,which indicates the contribution of regional weathering input from the South Asian continent to the Indian Ocean.The results show a long-term increase in △ε_(Nd) and thus provide the first critical evidence of enhanced South Asian weathering input since the late Eocene.The evolution coincided well with major pulses of surface uplift in the HTP and global climatic transitions.Our foraminiferal eNd record suggests that tectonic uplift and silicate weathering in South Asia,especially in the Himalayas,might have played a significant role in the late Cenozoic cooling. | Zehua Song Shiming Wan Christophe Colin Christian France-Lanord Zhaojie Yu Arnaud Dapoigny Hualong Jin Mengjun Li Jin Zhang Debo Zhao Xuefa Shi Anchun Li | 2023 | Science Bulletin2023，，3： | 2 |
