| 1 | Comparing the Diagnostic Criteria for Gestational Diabetes Mellitus of World Health Organization 2013 with 1999 in Chinese Population显示文摘INTRODUCTION Gestational diabetes mellitus (GDM) was earlier defined as 'hyperglycemia first recognized during pregnancy' and has more recently been described by American Diabetes Association (ADA) (2012) as diabetes diagnosed during pregnancy that is not clearly overt diabetes.[1] The hyperglycemia and adverse pregnancy outcomes study (HAPO) demonstrated that the risk of adverse maternal,fetal,and neonatal outcomes continuously increase as a function of maternal glycemia at 24-28 weeks,even within ranges previously considered normal for pregnancy.[2] After reviewing the results of the HAPO study,many international diabetes study groups,including the International Association of Diabetes and Pregnancy Study Groups and ADA have adopted the 75 g oral glucose tolerance test (OGTT) at 24-28 weeks as a screening and diagnostic test and defined new cut-off values for GDM diagnosis.The Ministry of Health of China published the criteria for GDM,that is the same as the ADA criteria on July 1,2011.World Health Organization (WHO) has recommended the 75 g OGTT with different cut-offvalues as a diagnostic test since 1999,changed its recommendation on 2013.In Hongkong and Yunnan province in China,most hospital adopted the WHO 1999 criteria,nevertheless,there is no evidence of multicenter and large sample to show that the GDM population within the same ethnic group diagnosed by the new WHO criteria matches those diagnosed by the old one and consistency between the two criteria has not been reported.Thus,we conducted this study to analyze the two criteria in Chinese pregnant women. | Weiwei Zhu Huixia Yang Yumei Wei Zilian Wang Xuelan Li Hairong Wu Nan Li Meihua Zhang Xinghui Liu Hua Zhang Yunhui Wang Jianmin Niu Yujie Gan Liruo Zhong Yunfeng Wang Anil Kapur | 2015 | Chinese Medical Journal2015，，1： | 42 |
| 2 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021，41，11： | 29 |
| 3 | Interaction of NPK Fertilizers During Their Transformation in Soils: I. Dynamic Changes of Soil pH显示文摘Dynamic changes of soil pH as influenced by ammonium sulfate (AS), monocalcium phosphate (MCP),potassium chloride (KCl) and their interaction in soils were evaluated in incubation experiments. Applyingthese fertilizers significantly reduced soil pH values in all cases and followed sequences of AS > MCP >KCl, MCP > KCl > AS and KCl > AS > MCP for the paddy, calcareous and red soils, respectively. TheAS-induced reduction of pH in the three soils followed the sequence of red soil > paddy soil > calcareous soil,while in MCP and KCl systems the reduction of pH followed the sequences of calcareous soil > paddy soil >red soil and red soil > calcareous soil > paddy soil, respectively. The interactions of the NPK fertilizers on pHwere significant. MCP plus KCl or MCP plus AS reduced pH values more than the fertilizers applied solelyin the paddy soil, but AS partly counteracted the effect of MCP on pH in the 1 d sample of the calcareoussoil. The effect of MCP on pH was trivial when MCP was applied in combination with KCl or AS in the redsoil. When applied in combination with AS, KCl did not affect soil pH initially, but suppressed the reductionof pH at the later incubation stage, which was related to inhibition of nitrification by KCl in the soils. | WANG HUOYAN, ZHOU JIANMIN, CHEN XIAOQIN, LI SHOUTIAN, DU CHANGWEN and DONG CAIXIAInstitute of Soil Science, the Chinese Academy of Sciences, Nanjing 210008 (China) | 2003 | Pedosphere2003，13，3： | 28 |
| 4 | Identification of a Stable Quantitative Trait Locus for Percentage Grains with White Chalkiness in Rice (Oryza sativa)显示文摘High chalkiness is a major problem in many rice-producing areas of the world, especially in hybrid rice (Oryza sativa L.) in China. We previously showed a major quantitative trait locus for the percentage of grains with white chalkiness (QTLqPGWC-8) in the interval G1149-R727 on chromosome 8 using a chromosome segment substitution line (CSSL). Here, we selected the line-CSSL50 harboring the QTLqPGWC-8 allele from the CSSLs derived from a cross between Asominori (as a recurrent parent) and IR24 (as a donor parent), which had higher percentage chalkiness, markedly different from that of Asominori. There were also significant differences in starch granules, appearance of amylose content (AAC) and milling qualities between Asominori and CSSL50, but not in grain size or thousand grain weight (TGW). The BC4F2 and BC4F3 populations from a cross between CSSL50 and Asominori were used for fine mapping of qPGWC-8. We narrowed down the location of this QTL to a 142 kb region between Indel markers 8G-7 and 8G-9. QTLqPGWC-8 accounted for 50.9% of the difference in PGWC between the parents. The markers tightly linked to qPGWC-8 should facilitate cloning of the gene underlying this QTL and will be of value for marker-assisted selection in breeding rice varieties with better grain quality. | Tao Guo Xiaolu Liu Xiangyuan Wan Jianfeng Weng Shijia Liu Xi Liu Mingjiang Chen Jingjing Li Ning Su Fuqing Wu Zhijun Cheng Xiuping Guo Cailin Lei Jiulin Wang Ling jiang Jianmin Wan | 2011 | Journal of Integrative Plant Biology2011，53，8： | 25 |
| 5 | SHRIMP U-Pb zircon dating of the Ordos Basin basement and its tectonic significance显示文摘SHRIMP U-Pb zircon 207 Pb/206 Pb ages were obtained from two drill cores from the basement of the Ordos Basin.A garnet-sillimanite-biotite-plagioclase gneiss(QI1-1) from the western Ordos Basin basement yielded an average age of 2031 10 Ma.Based on the mineral assemblages,the source material of the gneiss is speculated to be pelitic-felsic system.A gneissic two-mica granite(Long1-1) from the eastern Ordos Basin basement yielded an average age of 2035 10 Ma.The zircons from both samples exhibit magmatic growth pattern.The shapes of the zircons suggest that the zircons should crystallize from a granitic of felsic volcanic terrain.The ages and the characters of zircons are consisitent with the other researches in the Ordos Basin and indicate that the basement of the Ordos Basin had experienced an intensive magmatic epsode during the late Paleoproterozoic period.The date from this study suggest the possible existences of a Paleoproterozoic mobile tectonic belt in the region.The reconstruction of such a belt is critical for understanding the tectonomagmatic evolution of the western block of the North China Craton. | HU JianMin LIU XinShe LI ZhenHong ZHAO Yue ZHANG ShuanHong LIU XiaoChun QU HongJie CHEN Hong | 2013 | Chinese Science Bulletin2013，58，1： | 21 |
| 6 | Observation and analysis of atmospheric volatile organic compounds in a typical petrochemical area in Yangtze River Delta, China显示文摘Volatile organic compounds(VOCs) are a kind of important precursors for ozone photochemical formation. In this study, VOCs were measured from November 5 th, 2013 to January 6 th, 2014 at the Second Jinshan Industrial Area, Shanghai, China. The results showed that the measured VOCs were dominated by alkanes(41.8%), followed by aromatics(20.1%), alkenes(17.9%), and halo-hydrocarbons(12.5%). The daily trend of the VOC concentration showed a bimodal feature due to the rush-hour traffic in the morning and at nightfall. Based on the VOC concentration, a receptor model of Positive Matrix Factorization(PMF) coupled with the information related to VOC sources was applied to identify the major VOC emissions. The result showed five major VOC sources: solvent use and industrial processes were responsible for about 30% of the ambient VOCs, followed by rubber chemical industrial emissions(23%), refinery and petrochemical industrial emissions(21%), fuel evaporations(13%) and vehicular emissions(13%). The contribution of generalized industrial emissions was about 74% and significantly higher than that made by vehicle exhaust. Using a propylene-equivalent method, alkenes displayed the highest concentration, followed by aromatics and alkanes. Based on a maximum incremental reactivity(MIR)method, the average hourly ozone formation potential(OFP) of VOCs is 220.49 ppbv. The most significant source for ozone chemical formation was identified to be rubber chemical industrial emissions, following one by vehicular emission. The data shown herein may provide useful information to develop effective VOC pollution control strategies in industrialized area. | Yunchen Zhang Rui Li Hongbo Fu Dong Zhou Jianmin Chen | 2018 | Journal of Environmental Sciences2018，30，9： | 21 |
| 7 | Epidemiological and risk analysis of the H7N9 subtype influenza outbreak in China at its early stage显示文摘Dozens of human cases infected with H7N9 subtype avian influenza virus (AIV) have been confirmed in China since March, 2013. Distribution data of sexes, ages, professions and regions of the cases were analyzed in this report. The results showed that the elderly cases, especially the male elderly, were significantly more than expected, which is different from human cases of H5N1 avian influenza and human cases of the pandemic H1N1 influenza. The outbreak was rated as a Grade Ⅲ (severe) outbreak, and it would evolve into a Grade IV (very severe) outbreak soon, using a method reported previously. The H7N9 AIV will probably circulate in humans, birds and pigs for years. Moreover, with the driving force of natural selection, the virus will probably evolve into highly pathogenic AIV in birds, and into a deadly pandemic influenza virus in humans. Therefore, the H7N9 outbreak has been assumed severe, and it is likely to become very or extremely severe in the future, highlighting the emergent need of forceful scientific measures to eliminate any infected animal flocks. We also described two possible mild scenarios of the future evolution of the outbreak. | ZHUANG QingYe WANG SuChun WU MeiLi LIU Shuo JIANG WenMing HOU GuangYu LI JinPing WANG KaiCheng YU JianMin CHEN JiMing CHEN JiWang | 2013 | Chinese Science Bulletin2013，58，26： | 18 |
| 8 | Using Hourly Measurements to Explore the Role of Secondary Inorganic Aerosol in PM_(2.5)during Haze and Fog in Hangzhou, China显示文摘This paper explores the role of the secondary inorganic aerosol(SIA) species ammonium, NH+4, nitrate, NO-3, and sulfate,SO2-4, during haze and fog events using hourly mass concentrations of PM2.5measured at a suburban site in Hangzhou,China. A total of 546 samples were collected between 1 April and 8 May 2012. The samples were analyzed and classified as clear, haze or fog depending on visibility and relative humidity(RH). The contribution of SIA species to PM2.5mass increased to ~50% during haze and fog. The mass contribution of nitrate to PM2.5increased from 11% during clear to 20%during haze episodes. Nitrate mass exceeded sulfate mass during haze, while near equal concentrations were observed during fog episodes. The role of RH on the correlation between concentrations of SIA and visibility was examined, with optimal correlation at 60%–70% RH. The total acidity during clear, haze and fog periods was 42.38, 48.38 and 45.51 nmol m-3,respectively, indicating that sulfate, nitrate and chloride were not neutralized by ammonium during any period. The nitrate to sulfate molar ratio, as a function of the ammonium to sulfate molar ratio, indicated that nitrate formation during fog started at a higher ammonium to sulfate molar ratio compared to clear and haze periods. During haze and fog, the nitrate oxidation ratio increased by a factor of 1.6–1.7, while the sulfur oxidation ratio increased by a factor of 1.2–1.5, indicating that both gaseous NO2 and SO2were involved in the reduced visibility. | Roeland Cornelis JANSEN SHI Yang CHEN Jianmin HU YunJie XU Chang HONG Shengmao LI Jiao ZHANG Min | 2014 | Advances in Atmospheric Sciences2014，31，6： | 15 |
| 9 | Phenolic Acids in Plant-Soil-Microbe System: A Review显示文摘Phenolic acids are very common compounds in pedosphere. The objective of this review was to summarize the current knowledge of the behaviors of phenolic acids in plant-soil-microbe system. When phenolic acids originated from leaching, decomposition and exudation of living and dead plant tissues enter soils, they can react physicochemically with soil particle surfaces and/or incorporate into humic matter. Phenolic acids desorbed from soil particle surfaces and remained in solution phase can be utilized by microbe as carbon sources and absorbed by plants. The degradation products of phenolic acids by microbe include some organic and/or inorganic compounds such as new phenolic acids. In addition, phenolic acids in soils can stimulate population and activity of microbe. Phenolic acids can inhibit plants growth by affecting ion leakage, phytohormone activity, membrane permeability, hydraulic conductivity, net nutrient uptake, and enzyme activity. Behaviors of phenolic acids in soils are influenced by other organic compounds (phenolic acids, methionine, glucose, etc.) and/or inorganic ions. The role of phenolic acids as allelopathic agents should not be neglected only based on their low specific concentrations in natural soils, because numbers and interactions of phenolic acids will increase their allelopathic activities. | LI SHOUTIAN, ZHOU JIANMIN, WANG HUOYAN and CHEN XIAOQIN Institute of Soil Science, the Chinese Academy of Sciences, P.

| 11 | Cotton-derived oxygen/sulfur co-doped hard carbon as advanced anode material for potassium-ion batteries显示文摘Hard carbon is regarded as promising anode materials for potassium-ion batteries(KIBs)owing to their low price and easy availability.However,the limited rate capability still needs to be improved.Herein,we demonstrate the fabrication of oxygen/sulfur co-doped hard carbon through a facile hydrolyzationsulfuration process of skimmed cotton.The simultaneous dopants significantly improve potassium ion diffusion rate.When served as the anode for KIBs,this hydrolyzed hard carbon delivered a high reversible capacity(409 mAh/g at 0.1 A/g),superior rate capability(135 mAh/g at 2 A/g)and excellent cyclability(about 120 mAh/g overt 500 cycles at 2 A/g).This work provides a facile strategy to prepare low-cost doped-hard carbon with superior potassium storage property. | Baolin Xu Shihan Qi Fang Li Xiaoxin Peng Jinfeng Cai Jiaojiao Liang Jianmin Ma | 2020 | Chinese Chemical Letters2020，31，1： | 12 |
| 12 | Understanding unusually high levels of peroxyacetyl nitrate(PAN) in winter in Urban Jinan,China显示文摘Peroxyacetyl nitrate(PAN), as a major secondary pollutant, has gained increasing worldwide attentions, but relevant studies in China are still quite limited. During winter of 2015 to summer of 2016, the ambient levels of PAN were measured continuously by an automatic gas chromatograph equipped with an electron capture detector(GC–ECD) analyzer at an urban site in Jinan(China), with related parameters including concentrations of O3, NO, NO_2, PM_(2.5), HONO,the photolysis rate constant of NO_2 and meteorological factors observed concurrently. The mean and maximum values of PAN concentration were(1.89 ± 1.42) and 9.61 ppbv respectively in winter, and(2.54 ± 1.44) and 13.47 ppbv respectively in summer. Unusually high levels of PAN were observed during severe haze episodes in winter, and the formation mechanisms of them were emphatically discussed. Study showed that high levels of PAN in winter were mainly caused by local accumulation and strong photochemical reactions during haze episodes, while mass transport played only a minor role. Accelerated photochemical reactions(compared to winter days without haze) during haze episodes were deduced by the higher concentrations but shorter lifetimes of PAN, which was further supported by the sufficient solar radiation in the photolysis band along with the high concentrations of precursors(NO_2, VOCs) and HONO during haze episodes. In addition, significant PAN accumulation during calm weather of haze episodes was verified by meteorological data. | Lu Liu Xinfeng Wang Jianmin Chen Likun Xue Wenxing Wang Liang Wen Dandan Li Tianshu Chen | 2018 | Journal of Environmental Sciences2018，30，9： | 10 |
| 13 | Interfacial structure design of MXene-based nanomaterials for electrochemical energy storage and conversion显示文摘2D transition metal carbides,carbonitrides,and nitrides known as MXenes possess high electrical conductivity,large redox active surface area,rich surface chemistry,and tunable structures.Benefiting from these exceptional chemical and physical properties,the applications of MXenes for electrochemical energy storage and conversion have attracted increasing research interests around the world.Notably,the electrochemical performances of MXenes are directly dependent on their synthesis conditions,interfacial chemistries and structural configurations.In this review,we summarize the synthesis techniques of MXenes,as well as the recent advances in the interfacial structure design of MXene-based nanomaterials for electrochemical energy storage and conversion applications.Additionally,we provide an in-depth discussion on the relationship between interfacial structure and electrochemical performance from the perspectives of energy storage and electrocatalysis mechanisms.Finally,the challenges and insights for the future research of interfacial structure design of MXenes are outlined. | Jianmin Luo Edward Matios Huan Wang Xinyong Tao Weiyang Li | 2020 | InfoMat2020，2，6： | 10 |
| 14 | Clinical risk score for invasive fungal diseases in patients with hematological malignancies undergoing chemotherapy:China Assessment of Antifungal Therapy in Hematological Diseases (CAESAR) study显示文摘Invasive fungal disease (IFD) is a major infectious complication in patients with hematological malignancies.In this study,we examined 4889 courses of chemotherapy in patients with hematological diseases to establish a training dataset (n=3500) by simple random sampling to develop a weighted risk score for proven or probable IFD through multivariate regression,which included the following variables: male patients,induction chemotherapy for newly diagnosed or relapsed disease,neutropenia,neutropenia longer than 10 days,hypoalbuminemia,central-venous catheter,and history of IFD.The patients were classified into three groups,which had low (0-10,~1.2%),intermediate (11-15,6.4%),and high risk (> 15,17.5%) of IFD.In the validation set (n=1389),the IFD incidences of the groups were ~1.4%,5.0%,and 21.4%.In addition,we demonstrated that antifungal prophylaxis offered no benefits in low-risk patients,whereas benefits were documented in intermediate (2.1% vs.6.6%,P=0.007) and high-risk patients (8.4% vs.23.3%,P=0.007).To make the risk score applicable for clinical settings,a pre-chemo risk score that deleted all unpredictable factors before chemotherapy was established,and it confirmed that anti-fungal prophylaxis was beneficial in patients with intermediate and high risk of IFD.In conclusion,an objective,weighted risk score for IFD was developed,and it may be useful in guiding antifungal prophylaxis. | Ling Wang Ying Wang Jiong Hu Yuqian Sun He Huang Jing Chen Jianyong Li Jun Ma Juan Li Yingmin Liang Jianmin Wang Yan Li Kang Yu Jianda Hu Jie Jin Chun Wang Depei Wu Yang Xiao Xiaojun Huang | 2019 | Frontiers of Medicine2019，13，3： | 10 |
| 15 | Growth of SnO_2 Nanoflowers on N-doped Carbon Nanofibers as Anode for Li-and Na-ion Batteries显示文摘It is urgent to solve the problems of the dramatic volume expansion and pulverization of SnO_2 anodes during cycling process in battery systems. To address this issue, we design a hybrid structure of N-doped carbon fibers@SnO_2 nanoflowers(NC@SnO_2) to overcome it in this work. The hybrid NC@SnO_2 is synthesized through the hydrothermal growth of SnO_2 nanoflowers on the surface of N-doped carbon fibers obtained by electrospinning. The NC is introduced not only to provide a support framework in guiding the growth of the SnO_2 nanoflowers and prevent the flower-like structures from agglomeration, but also serve as a conductive network to accelerate electronic transmission along one-dimensional structure effectively. When the hybrid NC@SnO_2 was served as anode, it exhibits a high discharge capacity of 750 Ah g^(-1) at 1 A g^(-1) after 100 cycles in Li-ion battery and 270 mAh g^(-1) at 100 mA g^(-1) for 100 cycles in Na-ion battery, respectively. | Jiaojiao Liang Chaochun Yuan Huanhuan Li Kai Fan Zengxi Wei Hanqi Sun Jianmin Ma | 2018 | Nano-Micro Letters2018，10，2： | 10 |
| 16 | Regulation of extracellular signal-regulated kinase 1/2 influences hippocampal neuronal survival in a rat model of diabetic cerebral ischemia显示文摘Activation of extracellular signal-regulated kinase 1/2 has been demonstrated in acute brain ischemia. We hypothesized that activated extracellular signal-regulated kinase 1/2 can protect hippocampal neurons from injury in a diabetic model after cerebral ischemia/reperfusion. In this study, transient whole-brain ischemia was induced by four-vessel occlusion in normal and diabetic rats, and extracellular signal-regulated kinase 1/2 inhibitor(U0126) was administered into diabetic rats 30 minutes before ischemia as a pretreatment. Results showed that the number of surviving neurons in the hippocampal CA1 region was reduced, extracellular signal-regulated kinase 1/2 phosphorylation and Ku70 activity were decreased, and pro-apoptotic Bax expression was upregulated after intervention using U0126. These findings demonstrate that inhibition of extracellular signal-regulated kinase 1/2 activity aggravated neuronal loss in the hippocampus in a diabetic rat after cerebral ischemia/reperfusion, further decreased DNA repairing ability and accelerated apoptosis in hippocampal neurons. Extracellular signal-regulated kinase 1/2 activation plays a neuroprotective role in hippocampal neurons in a diabetic rat after cerebral ischemia/ reperfusion. | Yaning Zhao Jianmin Li Qiqun Tang Pan Zhang Liwei Jing Changxiang Chen Shuxing Li | 2014 | Neural Regeneration Research2014，9，7： | 10 |
| 17 | Petrogenetic contrastive studies on the Mesozoic early stage ore-bearing and late stage ore-barren granites from the southern Anhui Province显示文摘Yanshanian magmatisms are intensive in the southern Anhui Province and can be divided into early(152–137 Ma)and late(136–122 Ma) stages. A Yanshanian granitic zone was found to crop out along Qingshan to Changgai areas in the Tunxi district in Field investigation which has a genetic link with molybdenum multiple metal mineralization. To be a representative syenitic granite in the southern Anhui Province, the Huangshan pluton has not been found so far to have any genetic link with mineralization. Zircon LA-ICP-MS dating indicate that the four granitic bodies from the Qingshan-Changgai zone have concurrent formed ages from 140±4 to 141±2 Ma, belonging to the Yanshanian early stage magmatism. However, the Huangshan granite is dated to be 129±2 Ma, belonging to the Yanshanian late stage magmatism. The Qingshan-Changgai granites show high SiO2 and K2 O contents, low P2O5 contents and middle Al2O3 contents and are high-K calc-alkaline series metaluminum I-type granite. These rocks are characterized by enrichments in the large ion lithophile elements and light rare earth elements(REE), depletions in the high field-strength elements, and middle degree negative anomalies of Eu, geochemical features of arc or continent crustal derived magma affinities. These rocks have 87Sr/86Sr(t) ratios from 0.7120 to 0.7125, εNd(t) values from.7.24 to.4.38 and zircon εHf(t) values of.4.4 to 6.7, similar to that of the coeval ore-bearing granodiorites in the southern Anhui Province. Integrated geochemical studies indicate that the Yanshanian ore-bearing granodiorites were formed by partial melting of the Meso-Neoproterozoic accreted thickened low crust. Meanwhile, the Qingshan-Changgai granites were formed through a AFC process of plagioclase+amphibole+Shangxi Group of magmas that formed the ore-bearing granodiorites. The Huangshan granites are characterized by high SiO2 and K2 O contents, moderate Al2O3 contents, seagull shape REE distributed pattern and distinct Eu negative abnormities. Comparing with the Qingshan-Changgai granites, the Huangshan granites show more Ba, Sr, P,and Ti negative abnormities with no Nb and Ta depletions and are high-K calc-alkaline series metaluminum A-type granite. εHf(t)values of the Huangshan granites are from.6.6 to.1.2, similar to that of the early stage ore-bearing granodiorites, indicating that they were also formed by anatexis of the Meso-Neoproterozoic accreted crust, but their magma sources might be residual granulitic crust which ever underwent Yanshanian early stage I-type intermediate-acid magma extraction. Comparing studies on the two stages granites indicate that the early stage granites derived from a relative thickened low crust under a lower temperature condition. Their magma sources were Meso-Neoproterozoic accreted crust which enriched in ore-forming materials and further became more enriched through processes of magma AFC evolution. However, the late stage A-type granites originated from relative shallow crust under a higher temperature condition. Their magma source was depleted in ore-forming materials due to the early stage magma extraction and thus had weak ore-forming capacity. From early to late stage, the magmatisms tectonic setting translated from post-orogenic to anorogenic and the later corresponded to a back-arc extensional setting as increase of the slab subducted angle of the Paleo-Pacific plate. | YAN Jun HOU TianJie WANG AiGuo WANG DeEn ZHANG DingYuan WENG WangFei LIU JianMin LIU XiaoQiang LI QuanZhong | 2017 | Science China Earth Sciences2017，60，11： | 9 |
| 18 | Observations of atmospheric pollutants at Lhasa during 2014-2015:Pollution status and the influence of meteorological factors显示文摘Atmospheric pollutants including SO_2, NO_2, CO, O_3 and inhalable particulate matter(PM2.5 and PM10) were monitored continuously from March 2014 to February 2015 to investigate characteristics of air pollution at Lhasa, Tibetan Plateau. Species exhibited similar seasonal variations except O_3, with the peaks in winter but low valleys in summer. The maximum O_3 concentration was observed in spring, followed by summer, autumn, and winter. The positive correlation between O_3 and PM10 in spring indicated similar sources of them, and was assumed to be turbulent transport. Temperature was the dominant meteorological factor for most species in spring. High temperature accelerates O_3 photochemistry, and favors air disturbance which is conductive to dust resuspension in spring. Relative humidity(RH) and atmospheric pressure were the main meteorological factors in summer. RH showed negative correlations with species, while atmospheric pressure posed opposite situation. Wind speed(WS) was the dominant meteorological factor in autumn, the negative correlations between WS and species indicated diffusion by wind. Most species showed non-significant correlations with meteorological factors in winter, indicating the dependence of pollution on source emission rather than restriction by meteorology. Pollution weather character indicated that emissions were from biomass burning and dust suspension, and meteorological factors also played an important role. Air stream injection from the stratosphere was observed during O_3 pollution period. Air parcels from Southwest Asia were observed during air pollution period in winter. An enhancement in air pollutants such as O_3 would be expected in the future, more attention should be given to countermeasures for prevention of air pollution in the future. | Bu Duo Lulu Cui Zhenzhen Wang Rui Li Liwu Zhang Hongbo Fu Jianmin Chen Huifang Zhang A.Qiong | 2018 | Journal of Environmental Sciences2018，30，1： | 9 |
| 19 | The Epitope Study on the SARS-CoV Nucleocapsid Protein显示文摘The nucleocapsid protein (N protein) has been found to be an antigenic protein in a number of coronaviruses. Whether the N protein in severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is antigenic remains to be elucidated. Using Western blot and Enzyme-linked Immunosorbent Assay (ELISA),the recombinant N proteins and the synthesized peptides derived from the N protein were screened in sera from SARS patients. All patient sera in this study displayed strong positive immunoreactivities against the recombinant N proteins,whereas normal sera gave negative immunoresponses to these proteins, indicating that the N protein of SARS-CoV is an antigenic protein. Furthermore, the epitope sites in the N protein were determined by competition experiments, in which the recombinant proteins or the synthesized peptides competed against the SARS-CoV proteins to bind to the antibodies raised in SARS sera. One epitope site located at the C-terminus was confirmed as the most antigenic region in this protein. A detailed screening of peptide with ELISA demonstrated that the amino sequence from Codons 371 to 407 was the epitope site at the C-terminus of the N protein. Understanding of the epitope sites could be very significant for developing an effective diagnostic approach to SARS. | Shuting Li, Liang Lin, Hao Wang, Jianning Yin, Yan Ren, Zhe Zhao, Jie Wen, Cuiqi Zhou, Xumin Zhang, Xiaolei Li, Jingqiang Wang, Zhengfeng Zhou, Jinxiu Liu, Jianmin Shao, Tingting Lei, Jianqiu Fang, Ningzhi Xu, and Siqi LiuBeijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300, China & Beijing Proteomics Institute, Beijing 101300, China | 2003 | Genomics, Proteomics & Bioinformatics2003，1，3： | 9 |
| 20 | Chrysophanol protects against doxorubicin-induced cardiotoxicity by suppressing cellular PARylation显示文摘The clinical application of doxorubicin(DOX) in cancer chemotherapy is limited by its lifethreatening cardiotoxic effects. Chrysophanol(CHR), an anthraquinone compound isolated from the rhizome of Rheum palmatum L., is considered to play a broad role in a variety of biological processes.However, the effects of CHR’s cardioprotection in DOX-induced cardiomyopathy is poorly understood. In this study, we found that the cardiac apoptosis, mitochondrial injury and cellular PARylation levels were significantly increased in H9 C2 cells treated by Dox, while these effects were suppressed by CHR. Similar results were observed when PARP1 activity was suppressed by its inhibitors 3-aminobenzamide(3 AB)and ABT888. Ectopic expression of PARP1 effectively blocked this CHR’s cardioprotection against DOX-induced cardiomyocyte injury in H9 C2 cells. Furthermore, pre-administration with both CHR and 3 AB relieved DOX-induced cardiac apoptosis, mitochondrial impairment and heart dysfunction in Sprague–Dawley rat model. These results revealed that CHR protects against DOX-induced cardiotoxicity by suppressing cellular PARylation and provided critical evidence that PARylation may be a novel target for DOX-induced cardiomyopathy. | Jing Lu Jingyan Li Yuehuai Hu Zhen Guo Duanping Sun Panxia Wang Kaiteng Guo Dayue Darrel Duan Si Gao Jianmin Jiang Junjian Wang Peiqing Liu | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 8 |
