| 1 | Paleomagnetic dating of the Cenjiawan Paleolithic site in the Nihewan Basin, northern China显示文摘Rock magnetic and magnetostratigraphic investigations on a lacustrine sequence in the Nihewan Basin, northern China, which bears the Cenjiawan Paleolithic site, indicate that the dominant magnetic mineral and remanence carrier contained in the sediments is magnetite. While hematite co-exists with magnetite in some portions of the Cenjiawan sequence, where characteristic remanent magnetizations are carried by both magnetite and hematite. Measurements of anisotropy of magnetic susceptibility confirm that the Cenjiawan sequence has preserved the original sedimentary features and is suitable for magnetostratigraphic study. Paleomagnetic results indicate that the Cenjiawan Paleolithic site is formed just posterior to the Punaruu normal event, which is dated at about 1.1 Ma. Combined with the paleomagnetic results of the Donggutuo, Xiaochangliang and Majuangou sections, it is concluded that early humans were occupying the Nihewan Basin around 1.6, 1.3 and 1.1 Ma. This integrated result is significant to understanding the ability of migration and adaptation to the envi- ronment of early humans. | WANG Hongqiang1,2, DENG Chenglong1, ZHU Rixiang1 & XIE Fei3 1.

| 2 | Gasdynamic characteristics of toroidal shock and detonation wave converging显示文摘The modified CCW relation is applied to analyzing the shock, detonation wave converging and the role of chemical reactions in the process. Results indicate that the shock wave is strengthened faster than the detonation wave in the converging at the same initial Mach number. Euler equations implemented with a detailed chemical reaction model are solved to simulate toroidal shock and detonation wave converging. Gasdynamic characteristics of the converging are investigated, including wave interaction patterns, observable discrepancies and physical phenomena behind them. By comparing wave diffractions, converging processes and pressure evolutions in the focusing area, the different effects of chemical reactions on diffracting and converging processes are discussed and the analytic conclusion is demonstrated through the observation of numerical simulations. | TENG Honghui1,2 & JIANG Zonglin2 1.

| 4 | Thermostability of photosynthesis in two new chlorophyll b-less rice mutants显示文摘Leaves of the two new chlorophyll b-less rice mutants VG28-1, VG30-5 and the wild type rice cv. Zhonghua 11 were subjected to temperatures 28, 36, 40, 44 and 48℃ in the dark for 30 min or gradually elevated temperature from 30℃ to 80℃ at 0.5℃/min. The thermostability of photosynthetic apparatus was estimated by the changes in chlorophyll fluorescence parameters, photosynthetic rate and pigment content, chloroplast ultrastructure and tissue location of H2O2 accumulation. There were different patterns of Fo-temperature curves between the Chl b-less mutants and the wild type plant, and the temperature of Fo rising threshold was shifted 3℃ lower in the Chl b-less mutants (48℃) than in the wild type (51℃). At temperature up to about 45℃, chloroplasts were swollen and thylakoid grana became misty accompanied with the complete loss of photosynthetic oxygen evolution in the two Chl b-less mutants, but chloroplast ultrastruc- ture in the wild type showed no obvious alteration. After 55℃ exposure, the disordered thylakoid and significant H2O2 accumulation in leaves were found in the two Chl b-less mutants, whereas in the wild type plant, less H2O2 was accumulated and the swollen thylakoid still maintained a cer- tain extent of stacking. A large extent of the changes in qP, NPQ and Fv/Fm was consistent with the Pn decreasing rate in the Chl b-less mutants during high temperature treatment as compared with the wild type. The results indicated that the Chl b-less mutants showed a tendency for higher thermosensitivity, and loss of Chl b in LHC II could lead to less thermostability of PSII structure and function. Heat damage to photosynthetic apparatus might be partially attributed to the in- ternal oxidative stress produced at severely high temperature. | LIN Zhifang1,PENG Changlian1,Xu Xinlan1,LIN Guizhu 1 & ZHANG Jingliu2 1.South China Institute of Botany,Chinese Academy of Sciences,Guangdong Key Laboratory of Digital Botanical Garden,Guangzhou 510650,China 2.National Key Laboratory of Plant Molecular Genetics,Institute of Plant Physiology & Ecology,Shanghai Institutes of Biological Sci- ences,Chinese Academy of Sciences,Shanghai 200032,China | 2005 | Science China(Life Sciences)2005，48，2： | 4 |
| 5 | Characterization of plastic flow in two Zr-based bulk metallic glasses显示文摘Plastic deformation behaviors of Zr65Al10Ni10Cu15 and Zr52.5Al10Ni10Cu15Be12.5 bulk metallic glasses (BMGs) are studied by using the depth-sensing nanoindentation, microindentation and uniaxial compression. The Be-containing BMG exhibits a signifi- cantly improved overall plastic strain compared with the Be-free alloy during compressive tests. Both BMGs show a loading-rate-dependent serrated flow during nanoindentation measurements, but the Be-containing alloy exhibits a much lower critical loading rate for the disappearance of the serration than the Be-free BMG. The shear band patterns de- veloped during plastic deformation are investigated by microindentation technique, wherein much higher shear band density is found in the Be-containing alloy than in the Be-free alloy, indicating an easier nucleation of shear bands in the former BMG. The dif- ference in the plastic deformation behavior of the two BMGs can be explained by a free volume model. | XING Dongmei1,2, ZHANG Taihua1, LI Weihuo3 & WEI Bingchen3 1.

| 6 | Association of human leukocyte antigen DQB1 and DRB1 alleles with chronic hepatitis B显示文摘AIM: To investigate the effect of human leukocyte antigen(HLA) DRB1 and DQB1 alleles on the inactive and advanced stages of chronic hepatitis B.METHODS: Patient records at a single institution's hepatology clinic were reviewed. Demographic data, laboratory results, endoscopy results, virological parameters, biopsy scores and treatment statuses were recorded. In total, 355 patients were eligible for thestudy, of whom 226(63.7%) were male. Overall, 82(23.1%) were hepatitis B early antigen(HBeAg) positive, 87(24.5%) had cirrhosis, and 66(18.6%) had inactive disease. The presence of DQB1 and DRB1 alleles was determined by polymerase chain reaction with sequence-specific primers. The distribution of the genotyped alleles among patients with cirrhosis and patients with chronic active hepatitis was analyzed.RESULTS: The most frequent HLA DQB1 allele was DQB1*03:01(48.2%), and the most frequent HLA DRB1 allele was DRB1*13/14(51.8%). DQB1*05:01 was more frequent in patients with active disease than in inactive patients(27% vs 9.1%; P = 0.002, Pc = 0.026). DRB1*07 was rare in patients with cirrhosis compared with non-cirrhotics(3.4% vs 16%; P = 0.002, Pc = 0.022). Older age(P < 0.001) and male gender(P = 0.008) were the other factors that affected the presence of cirrhosis. In a multivariate logistic regression analysis, DRB1*07 remained a significant negative predictor of cirrhosis(P = 0.015). A bioinformatics analysis revealed that a polymorphic amino acid sequence in DRB1*07 may alter interaction with the T-cell recognition site.CONCLUSION: This study demonstrates that HLA alleles may influence cirrhosis development and disease activity in Turkish chronic hepatitis B patients. | Levent Doganay Arta Fejzullahu Seyma Katrinli Feruze Yilmaz Enc Oguzhan Ozturk Yasar Colak Celal Ulasoglu Ilyas Tuncer Gizem Dinler Doganay | 2014 | World Journal of Gastroenterology2014，20，25： | 3 |
| 7 | Stable isotopic analysis on sus bones from the Wanfabozi site, Tonghua, Jilin显示文摘In order to study the sus diets and explore the possibility to distinguish domestic pig from wild boar through dietary analysis, stable carbon and nitrogen isotopes of 28 pig bones from archaeological site of Wanfabozi in Tonghua City, Jilin Province were analyzed. The δ 13C and δ 15N values of uncontaminated bones show that the overall pigs in the site were generally herbivores and ate mainly C3 plants. Significant difference of δ15N values was observed between wild boar and domestic pigs, which may result from the higher consumption of animal protein in domestic pigs other than from that in wild boar, possibly from human leftover or waste,. The dietary difference between wild boar and domestic pigs has great potential to differentiate wild boar and domestic pigs in the early stage of pig domestication. | GUAN Li1, HU YaoWu2, TANG zhuoWei3, YANG YiMin2, DONG Yu1, CUI YaPing4 & WANG ChangSui2 1 Department of History of Science & Technology and Archaeometry University of Science and Technology of China, Hefei 230026, China 2 Department of Scientific History and Archaeometry School of the Humanities, Graduate University of Chinese Academy of Sci- ences, Beijing 100049, China 3 Laboratory of Environment Archaeology, Research Center for Chinese Frontier Archaeology Jilin University Changchun 130012, China 4 Museum of the West Han Dynasty Mausoleum of the Nanyue King, Guangzhou 510040, China | 2007 | Chinese Science Bulletin2007，52，24： | 3 |
