1High-precision timing of the Quaternary standard samples with thermal ionization mass spectrometry (TIMS) U-series method显示文摘Two national stalagmite standard (GBW04412, GBW04413) and one international coral standard (RKM4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of ( 234 U/ 238 U) act , ( 230 Th/ 234 U) act and age are all consistent in error range with the standard values obtained by using α spectrometry.Peng Zicheng Wang Zhaorong Sun Weidong Ma Zhibang Xia Ming Zhang Chenhui Chen Wenji Zhang Zhonglu An Zhisheng 1998Chinese Science Bulletin1998,43,4:14
2Sedimentary Characteristics and Paleoenvironmental Records of Zabuye Salt Lake,Tibetan Plateau,since 128 ka BP显示文摘This paper for the first time reveals high-resolution core records of Zabuye Salt Lake in the interior of the Qinghai-Tibet Plateau.According to 1346 samples taken continuously,relatively accurate ^(14)C,U-series disequilibrium and ESR ages have been obtained,thus revealing that the lake core ages from 0 to 83.63m of hole SZK02 are~800 to over 128 ka.In the paper,the lake core sedimentary characteristics(including the lithologies and mineral assemblages)are analyzed in detail and correlated with ostracod assemblages I to XX and sporopollen zones A to I,and on the basis of an integrated analysis of theδ^(18)0 values of authigenic calcium-magnesium carbonate and environmental proxies of minerals,sporopollen and microfossils in the lake core,a correlation has been made of oxygen isotope change between this lake core and the Greenland GISP2 and GRIP and Guliya ice cores,and the climate of Zabuye Salt Lake since 128 ka BP is divided into the last interglacial stage (including substages e,d,c,b and a)of oxygen isotope stage(OIS)5,early glacial stadial of the last glacial stage of OIS 4,interglacial stadial of the last glacial stage of OIS 3,late glacial stadial of the last glacial stage or Last Glacial Maximum of OIS 2 and postglacial state of OIS 1;in addition,6 Heinrich (H_6-H_1)events,Younger Dryas event and 8.2 ka BP cold event have been recognized.ZHENG Mianping YUAN Heran LIU Junying LI Yanhe MA Zhibang SUN Qing 2007Acta Geologica Sinica(English Edition)2007,81,5:10
3Holocene aeolian stratigraphic sequences in the eastern portion of the desert belt(sand seas and sandy lands) in northern China and their palaeoenvironmental implications显示文摘This paper presents the environmental history and its responses to palaeoclimatic changes since the start of the Holocene in the eastern portion of the desert belt(sand seas and sandy lands) in northern China by comparing the aeolian sandpalaeosol sequences and their palaeoclimatic proxies. The optically stimulated luminescence(OSL) ages of the aeolian sandpalaeosol sedimentary sequences and a series of palaeoenvironmental proxies show that:(1) The large-scale dune landscape currently in the Kubuqi Sand Sea was formed during the Holocene in general;and the palaeosol was generally developed during the period of 4–2 ka, indicating conditions favorable for vegetation growth, soil development, and organic carbon accumulation due to increased precipitation or effective moisture and weakened aeolian activities;the large-scale expansion of dunes in the recent 2 ka is closely linked to human activities. The variable discharge of the Yellow River with diversions for irrigation may have resulted in a more consistent supply of aeolian particles for dune field expansion.(2) The dune landscape of the Hunshandake Sandy Land was likely formed around 12 ka, and before this, the western part of the Hunshandake Sandy Land would have been covered by a single large lake;it was obviously wetter than today in the sandy land during the period of 9.6–3 ka and the palaeosols were developed at the same time. But the aeolian activities have not been completely dormant in this long-lasting wetter epoch;because the Holocene wetter period was likely time-transgressive across the region.(3) The palaeosol of the Hulunbuir Sandy Land began to develop as early as 14.5 ka, probably continuing until the last 2 ka. The palaeosol development of various dune fields in the eastern portion of the desert belt(sand seas and sandy lands) in northern China is spatially heterogeneous, and even the palaeosol development time in different locations within each sandy land is inconsistent. During the middle Holocene(especially the 7.5–3.5 ka), all the sandy lands were stabilized in general and the intensity of aeolian activities was significantly weakened. The number of palaeoenvironmental records in the eastern portion of the desert belt(sand seas and sandy lands) in northern China has increased rapidly in the past decade, but the amount of published data still does not match the vast extent of the dune fields. It does require much more in-depth palaeoenvironmental studies for a full understanding of the relationship between aeolian activities and climate change in northern China.Xiaoping YANG Peng LIANG Deguo ZHANG Hongwei LI Patrick RIOUAL Xulong WANG Bing XU Zhibang MA Qianqian LIU Xiaozong REN Fangen HU Yuxin HE Gang RAO Ninghua CHEN 2019Science China Earth Sciences2019,62,8:10
4High-precision U-series dating of Holocene corals from South China Sea by thermal ionization mass spectrometry(TIMS)显示文摘Using the isotopic diluting and thermal ionization mass spectrometric (TIMS) technique, the U-series dating procedure was established on the basis of measurement of national standard GBW04412. With this highly precise technique the Holocene corals from the South China Sea were dated. Comparison between this method and α-spectrometry was made. The results show that a thriving period of corals in the South China Sea appeared at 6 800—5 800 a BP, during which the paleosea level was the higher than at present in the Holecene.Zhibang Ma Ming Xia Chenghui Zhang Zicheng Pen Zhaorong Wang Weidong Sun Zhisheng An 1999Chinese Science Bulletin1999,44,10:4

10U-series dating on late Quaternary sediments from Balikun Lake显示文摘The U-series component-dating method has been employed to date the sediment core B-194 from Balikun Lake. 230Th/ 232Th and 234U/ 232Th ratios in various components of the samples dissolved in different concentration acids were measured respectively. The results indicate that there is a good relationship of the isotopic ratios between the solutions and the residues, and that uranium and thorium isotopic fractionations did not occur during acid leaching. Based on the U-series ages obtained by using component-dating method, a 144-ka time sequence was established corresponding to the upper 25-m interval of the B-194 core, which is in agreement with palaeomagnetic dating results. The fact that the palaeoclimatic and palaeoenvironmental record labeled with U-series ages is correlative with the deep-sea δ 18O SPECMAP also demonstrates that the U-series component-dating method can be used to date lake sediments.Jiaqi Liu Zhibang Ma 1998Chinese Science Bulletin1998,43,17:1

13Changes in motor function in the unaffected hand of stroke patients should not be ignored显示文摘Motor function changes in the unaffected hand of stroke patients with hemiplegia. These changes are often ignored by clinicians owing to the extent of motor disability of the affected hand. Finger tapping frequency and Lind-mark hand function score showed that the motor function of unaffected hands in stroke patients was poorer than that of a healthy control hand. After 2 weeks of rehabilitation treatment, motor function of the unaffected hand of stroke patients was obviously improved. Therefore, attention should also be paid to motor function in the unaffected hand of stroke patients with hemiplegia during rehabilitation.Lingli Zhang Peihong Li Zhibang Mao Xiang Qi Jun Zou Zhusheng Yu 2014Neural Regeneration Research2014,9,13:0
14Application of Genetic Rules of Quality Traits in the Selection of Watermelon Inbred Lines显示文摘On the basis of ascertaining the dominant and recessive relationship and separation ratio of quality traits such as leaf type and peel stripes,the separation of dominant and recessive traits was studied to infer whether the genes of the previous generation were homozygous.Individuals with homozygous recessive traits can be confirmed in F2 generation,and homozygous single lines with dominant traits can be confirmed in F3 generation,which speeds up the breeding process of watermelon inbred lines.Xiaodan LUO Shengcan HOU Zhibang HUO Zhiqiang CHENG Junlong FAN 2020Asian Agricultural Research2020,12,3:0
15Clinical and Pathological Observation on Infectious Serositis of Duck显示文摘According to clinical and pathological observation in infectious serositis of duck, the main signs of this disease were diarrhoea, breathing with difficulty, head tremble and movement beyond coordination. The pathological changes that had been found in 30 experimental ducks were fibrous pericarditis, hepatitis, and encephalitis. The fibrous serositis, liver fatty degeneration or focus necrosis,nonsuppurative encephalitis and serous-fibrous pneumonia were typical pathological changes of histology.Den Zhibang , Yang Lijun , and Zhu Shenghai Wuling University, Zhangjiajie 427000, China 2002Hunan Agricultural Science & Technology Newsletter2002,3,2:0
16Third molar-related knowledge,attitudes,behaviors,and medical history of 904 Chinese adults:a cross-sectional survey显示文摘This study investigated the perceptions and medical history of third molars(M3s)and assessed the prevalence of visible M3s(V-M3s)among 904 Chinese adults.The enrolled participants were interviewed to complete a structural questionnaire focused on sociodemographic information and their understanding of,attitudes toward,behaviors regarding,and medical history with respect to M3s.In addition,the number of V-M3s in the cohort was determined by oral examination.Logistic regression analysis was performed to explore the association between individuals'sociodemographic characteristics and their perception of M3s or the presence of V-M3s.The Chi-square test was used to compare the actions taken against symptomatic M3s and the corresponding outcomes among different groups divided according to respondents'sociodemographic factors.In total,904 completed questionnaires were gathered and analyzed.Nearly half(43.9%)of the respondents knew nothing about M3s,and only 12.7%provided correct answers to all the questions asked.Male sex,older age,occupation involving physical labor,and no previous dental experience were active factors in unawareness of M3s.Male sex was also significantly associated with the presence of at least one V-M3 and negative behavior about symptomatic M3s.In terms of medical history,192 participants reported having had at least one M3 extracted(438 in total),and 72.6%of the M3s were removed due to the presence of related symptoms or pathologies.In conclusion,the population investigated had a shortage of knowledge about M3s and adopted negative attitudes and actions about M3-related problems.Honglei QU Yang YANG Yi TIAN Zhibang LI Lijuan SUN Faming CHEN Beimin TIAN 2023Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023,24,10:0
17Experimental infecting method of infectious serositis on duck显示文摘The infectious serositis was transmitted to duck by Pasteurella anatipestifer through 4 paths:trachea, abdominal cavity, crop and web. The most effective path is foot web and the suitable experimental infectious dose of bacteria is 4.5×108~6×108 cfu.Deng Zhibang, and Yang Lijun College of Resource and Environment of Jishou University, Zhang Jiajie 427000, China 2003Hunan Agricultural Science & Technology Newsletter2003,4,1:0
18Centennial-scale monsoon collapses during Marine Isotope Stage(MIS)7e detected in a northern Chinese stalagmite record显示文摘Occurrence or absence of centennial-scale climatic variability during Marine Isotope Stage(MIS)7e,the first peak interval of the Penultimate Interglacial,remains ambiguous due to the limited available high-resolved records.Here,we present a decadal-resolved stalagmiteδ^(18)O record from northern China spanning from 242.3 to 236.8 ka BP,covering MIS7e.The composite KLSδ^(18)O record,integrating this study with the previous record in the same cave,shows a descending trend from TerminationⅢto MIS7e,which follows the increasing Northern Hemisphere summer insolation(NHSI).This observation further emphasizes the important influence of NHSI on the glacial/interglacial transition.There are more large-amplitude,millennial-to centennial-scale variability occurring during TerminationⅢcompared with MIS7e,implying that ice-sheet decay potentially plays an important role in climatic excursions.Four centennial-scale summer monsoon collapses,peaking at~242.1,~240.8,~239.3 and~238.2 ka BP,are detected in our new record,indicating the pervasiveness of the intra-interglacial climatic instability.Given the lack of solar activity and freshwater outbursts data during MIS7e,it is not possible to conclude about the drivers of the identified abrupt climatic anomalous.Following the dynamic mechanisms of sub-millennial climatic anomalous during early Holocene,we tentatively propose that slowdown of the meridional overturning circulation caused by freshwater fluxes into North Atlantic and/or attenuated solar irradiance is the potential forcing for the abrupt climate events within MIS7e.Additionally,attenuated solar irradiance could also result in climatic anomalies through low-latitude processes.Wuhui DUAN Ming TAN Lisheng WANG Xuefeng WANG Zhibang MA Linlin CUI Zhengyi XIAO 2023Science China Earth Sciences2023,66,12:0
