1On adjacent-vertex-distinguishing total coloring of graphs显示文摘In this paper, we present a new concept of the adjacent-vertex-distinguishing total coloring of graphs (briefly, AVDTC of graphs) and, meanwhile, have obtained the adjacent-vertex-distinguishing total chromatic number of some graphs such as cycle, complete graph, complete bipartite graph, fan, wheel and tree.ZHANG Zhongfu, CHEN Xiang’en, LI Jingwen, YAO Bing, LU Xinzhong & WANG Jianfang College of Mathematics and Information Science, Northwest Normal University, Lanzhou 730070, China Department of Computer, Lanzhou Normal College, Lanzhou 730070, China Institute of Applied Mathematics, Lanzhou Jiaotong University, Lanzhou 730070, China College of Information and Electrical Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China Institute of Applied Mathematics, Chinese Academy of Sciences, Beijing 100080, China 2005Science China Mathematics2005,48,3:173
2Increasing the frequency of CIK cells adoptive immunotherapy may decrease risk of death in gastric cancer patients显示文摘AIM: To analyze the correlation between cytokineinduced killer (CIK) cells adoptive immunotherapy and cancer-related death in gastric cancer patients. METHODS: One hundred and fifty-six gastric cancer patients after operation at the Third Affiliated Hospital of Soochow University were enrolled in this study. Their clinical data including demographic characteristics, operation time, tumor size, pathological type and staging, tumor metastasis, outcome of chemotherapy or CIK cells adoptive immunotherapy, survival time or time of death were collected with a standard structured questionnaire. Kaplan-Meier method was used to estimate the median survival time, and the 2- and 5- year survival rates. Hazard risk (HR) and 95% confidence interval (95% CI) of CIK cells adoptive immunotherapy for gastric cancer were calculated using the two-stage time-dependent covariates Cox model. RESULTS: The survival time of gastric cancer patients was longer after CIK cells adoptive immunotherapy than after chemotherapy (χ 2 = 10.907, P = 0.001). The median survival time of gastric cancer patients was also longer after CIK cells adoptive immunotherapy than after chemotherapy (49 mo vs 27 mo, P < 0.05). The 2- and 5-year survival rates of gastric cancer patients were significantly higher after CIK cells adoptive immunotherapy than after chemotherapy (73.5% vs 52.6%, 40.4% vs 23.9%, P < 0.05). A significant difference was observed in the survival curve for patients who received CIK cells adoptive immunotherapy (0, 1-10, 11-25, and over 25 frequencies) (χ 2 = 14.534, P = 0.002). The frequencies of CIK cells adoptive immunotherapy were significantly related with the decreasing risk of death in gastric cancer patients after adjustment for sex and age of the patients, tumor stage and relapse (HR = 0.54, 95% CI: 0.36-0.80) when the first stage Cox model was used to define the subjects who remained alive beyond 36 mo as survivors. However, no correlation was observed between the frequencies of death in CIK cells adoptive immunotherapy and the risk of gastric cancer patients (HR = 1.09, 95% CI: 0.63-0.89) when the second stage Cox model was used to define the subjects who survived for more than 36 mo as survivors. CONCLUSION: The survival time of the gastric cancer patients treated with chemotherapy combined with CIK cells adoptive immunotherapy is significantly longer than that of the patients treated with chemotherapy alone and increasing the frequency of CIK cells adoptive immunotherapy seems to benefit patients more.Jing-Ting Jiang, Chang-Ping Wu, Lu-Jun Chen, Xiao Zheng, Department of Tumor Biological Treatment, Third Affiliated Hospital of Soochow University, Changzhou 213003, Jiangsu Province, China Yi-Bei Zhu, Jing Sun, Xue-Guang Zhang, Key Laboratory of Stem Cell of Jiangsu Province, Institute of Biotechnology, Key Laboratory of Clinical Immunology of Jiangsu Province, Soochow University, Suzhou 215123, Jiangsu Province, China Yue-Ping Shen, Wen-Xiang Wei, Department of Medicine, Soochow University, Suzhou 215123, Jiangsu Province, China Bin-Feng Lu, Department of Immunology, University of Pitts- burgh School of Medicine, Pittsburgh, PA 15261, United States 2010World Journal of Gastroenterology2010,16,48:82
3XS0601 REDUCES THE INCIDENCE OF RESTENOSIS: A PROSPECTIVE STUDY OF 335 PATIENTS UNDERGOING PERCUTANEOUS CORONARY INTERVENTION IN CHINA显示文摘Background XS0601, consisting of active ingredients (Chuangxiongol and paeoniflorin), has been shown to inhibit arterial neointimal hyperplasia in animal models and in preliminary human studies. The objective of this study was to evaluate the safety and efficacy of XS0601 in preventing restenosis following percutaneous coronary intervention (PCI). Methods A multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 patients were randomized into treatment with the oral administration of XS0601, or a placebo for 6 months after successful PCI. Angiographic follow-up was scheduled at 6 months, and clinical follow-ups performed at 1, 3 and 6 months after PCI. The primary end point was angiographic restenosis. The secondary end points were the combined incidence of death, target lesion nonfatal myocardial infarction, repeat angioplasty, and coronary artery bypass graft surgery. Results A total of 308 patients (91.9%) completed the study and 145 cases (47.1%) received angiographic follow-up. The restenosis rates were significantly reduced in the XS0601 group as compared with the placebo group (26.0% vs. 47.2%, P < 0.05), and the minimum lumen diameter (MLD) was greater [(2.08 ± 0.89) mm for XS0601 vs. (1.73 ± 0.94) mm for placebo, P < 0.05]. XS0601 also significantly reduced the combined incidence of major adverse cardiac event (10.4% in the XS0601 group vs. 22.7% in the placebo group, P < 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in XS0601 group (7.1% and 11.0%) as compared with those in placebo group (19.5% and 42.9%) (P < 0.05). No significant side effects occurred within the 6-month follow-up period in the XS0601 group. Conclusion Administration of XS0601 for 6 months is demonstrated to be safe and effective in reducing restenosis in post-PCI patients.CHEN Ke-ji SHI Da-zhuo XU Hao LUE Shu-zheng LI Tian-chang KE Yuan-nan ZHANG Min-zhou LU Xiao-yan SUN Rui-yuan YOU Shi-jie 2006Chinese Medical Journal2006,,1:83
4Tectonics of South China Continent and its implications显示文摘This paper aims at exploring the tectonic characteristics of the South China Continent(SCC)and extracting the universal tectonic rules from these characteristics,to help enrich the plate tectonic theory and better understand the continental dynamic system.For this purpose,here we conduct a multi-disciplinary investigation and combine it with the previous studies to reassess the tectonics and evolution of SCC and propose that the tectonic framework of the continent comprises two blocks,three types of tectonic units,four deformation systems,and four evolutionary stages with distinctive mechanism and tectonic characteristics since the Neoproterozoic.The four evolutionary stages are:(1)The amalgamation and break-up of the Neoproterozoic plates,typically the intracontinental rifting.(2)The early Paleozoic and Mesozoic intracontinental orogeny confined by plate tectonics,forming two composite tectonic domains.(3)The parallel operation of the Yangtze cratonization and intracontinental orogeny,and multi-phase reactivation of the Yangtze craton.(4)The association and differentiation evolution of plate tectonics and intracontinental tectonics,and the dynamic characteristics under the Meso-Cenozoic modern global plate tectonic regime.ZHANG GuoWei GUO AnLin WANG YueJun LI SanZhong DONG YunPeng LIU ShaoFeng HE DengFa CHENG ShunYou LU RuKui YAO AnPing 2013Science China Earth Sciences2013,56,11:88
5Exosome and Exosomal MicroRNA: Trafficking, Sorting, and Function显示文摘Exosomes are 40–100 nm nano-sized vesicles that are released from many cell types into the extracellular space. Such vesicles are widely distributed in various body fluids. Recently,m RNAs and micro RNAs(mi RNAs) have been identified in exosomes, which can be taken up by neighboring or distant cells and subsequently modulate recipient cells. This suggests an active sorting mechanism of exosomal mi RNAs, since the mi RNA profiles of exosomes may differ from those of the parent cells. Exosomal mi RNAs play an important role in disease progression, and can stimulate angiogenesis and facilitate metastasis in cancers. In this review, we will introduce the origin and the trafficking of exosomes between cells, display current research on the sorting mechanism of exosomal mi RNAs, and briefly describe how exosomes and their mi RNAs function in recipient cells.Finally, we will discuss the potential applications of these mi RNA-containing vesicles in clinical settings.Jian Zhang Sha Li Lu Li Meng Li Chongye Guo Jun Yao Shuangli Mi 2015Genomics, Proteomics & Bioinformatics2015,13,1:162
6Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection.Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu 2020Science China(Life Sciences)2020,63,3:157
7Western North Pacific Tropical Cyclone Database Created by the China Meteorological Administration显示文摘This paper describes the access to, and the content, characteristics, and potential applications of the tropical cyclone(TC) database that is maintained and actively developed by the China Meteorological Administration, with the aim of facilitating its use in scientific research and operational services. This database records data relating to all TCs that have passed through the western North Pacific(WNP) and South China Sea(SCS) since 1949. TC data collection has expanded over recent decades via continuous TC monitoring using remote sensing and specialized field detection techniques,allowing collation of a multi-source TC database for the WNP and SCS that covers a long period, with wide coverage and many observational elements. This database now comprises a wide variety of information related to TCs, such as historical or real-time locations(i.e., best track and landfall), intensity, dynamic and thermal structures, wind strengths, precipitation amounts, and frequency. This database will support ongoing research into the processes and patterns associated with TC climatic activity and TC forecasting.Xiaoqin LU Hui YU Ming YING Bingke ZHAO Shuai ZHANG Limin LIN Lina BAI Rijin WAN 2021Advances in Atmospheric Sciences2021,38,4:96
8黄河河口镇至龙门区间来水来沙变化及其对水利水保措施的响应显示文摘采用现代统计学中的变点分析法、历时曲线法和双累积曲线法对黄河中游河口镇到龙门区间1952-2000年降水、径流和泥沙量进行了综合分析。结果表明:黄河河龙区间多年平均降水量为434.5mm,径流量53.3×108m3,输沙量7.2×108t。上世纪50年代以来,区间面平均降雨量并未发生显著的趋势性变化,而径流和输沙量均发生了显著性趋势性减少,但在这种趋势性减少过程中,上世纪90年代则表现出微弱增加。与前期相比,在消除降雨量影响后,区间径流量降低幅度一般在20%-30%,而输沙量在低频率部分(相当于汛期)减小幅度达40%,高频部分(相当于非汛期)有所增加。根据建立的区间面平均降雨量与径流量及输沙量关系分析,黄河河龙区间因人类活动的直接作用使区间径流量年均减少18.8×108m3,输沙量年均减少3.7×108t。与前期相比,区域水土保持措施是区间径流和泥沙减少的主要驱动力。穆兴民 巴桑赤烈 ZHANG Lu 高鹏 王飞 张晓萍 2007泥沙研究2007,32,2:63

14On the origin and continuing evolution of SARS-CoV-2显示文摘The SARS-Co V-2 epidemic started in late December 2019 in Wuhan, China, and has since impacted a large portion of China and raised major global concern. Herein, we investigated the extent of molecular divergence between SARS-CoV-2 and other related coronaviruses. Although we found only 4% variability in genomic nucleotides between SARS-CoV-2 and a bat SARS-related coronavirus(SARSr-CoV;Ra TG13), the difference at neutral sites was 17%, suggesting the divergence between the two viruses is much larger than previously estimated. Our results suggest that the development of new variations in functional sites in the receptor-binding domain(RBD) of the spike seen in SARS-Co V-2 and viruses from pangolin SARSr-Co Vs are likely caused by natural selection besides recombination. Population genetic analyses of 103 SARS-CoV-2 genomes indicated that these viruses had two major lineages(designated L and S), that are well defined by two different SNPs that show nearly complete linkage across the viral strains sequenced to date. We found that L lineage was more prevalent than the S lineage within the limited patient samples we examined. The implication of these evolutionary changes on disease etiology remains unclear.These findings strongly underscores the urgent need for further comprehensive studies that combine viral genomic data, with epidemiological studies of coronavirus disease 2019(COVID-19).Xiaolu Tang Changcheng Wu Xiang Li Yuhe Song Xinmin Yao Xinkai Wu Yuange Duan Hong Zhang Yirong Wang Zhaohui Qian Jie Cui Jian Lu 2020National Science Review2020,7,6:67
15Wnt/b-catenin signaling plays an ever-expanding role in stem cell self-renewal,tumorigenesis and cancer chemoresistance显示文摘Wnt signaling transduces evolutionarily conserved pathways which play important roles in initiating and regulating a diverse range of cellular activities,including cell proliferation,calcium homeostasis,and cell polarity.The role of Wnt signaling in controlling cell proliferation and stem cell self-renewal is primarily carried out through the canonical pathway,which is the best-characterized the multiple Wnt signaling branches.The past 10 years has seen a rapid expansion in our understanding of the complexity of this pathway,as many new components of Wnt signaling have been identified and linked to signaling regulation,stem cell functions,and adult tissue homeostasis.Additionally,a substantial body of evidence links Wnt signaling to tumorigenesis of cancer types and implicates it in the development of cancer drug resistance.Thus,a better understanding of the mechanisms by which dysregulation of Wnt signaling precedes the development and progression of human cancer may hasten the development of pathway inhibitors to augment current therapy.This review summarizes and synthesizes our current knowledge of the canonical Wnt pathway in development and disease.We begin with an overview of the components of the canonical Wnt signaling pathway and delve into the role this pathway has been shown to play in stemness,tumorigenesis,and cancer drug resistance.Ultimately,we hope to present an organized collection of evidence implicating Wnt signaling in tumorigenesis and chemoresistance to facilitate the pursuit of Wnt pathway modulators that may improve outcomes of cancers in which Wnt signaling contributes to aggressive disease and/or treatment resistance.Maryam K.Mohammed Connie Shao Jing Wang Qiang Wei Xin Wang Zachary Collier Shengli Tang Hao Liu Fugui Zhang Jiayi Huang Dan Guo Minpeng Lu Feng Liu Jianxiang Liu Chao Ma Lewis L.Shi Aravind Athiviraham Tong-Chuan He Michael J.Lee 2016Genes & Diseases2016,3,1:70
16Cytological analysis and genetic control of rice anther development显示文摘Microsporogenesis and male gametogenesis are essential for the alternating life cycle of flowering plants between diploid sporophyte and haploid gametophyte generations.Rice(Oryza saliva) is the world's major staple food,and manipulation of pollen fertility is particularly important for the demands to increase rice grain yield.Towards a better understanding of the mechanisms controlling rice male reproductive development,we describe here the cytological changes of anther development through 14 stages,including cell division,differentiation and degeneration of somatic tissues consisting of four concentric cell layers surrounding and supporting reproductive cells as they form mature pollen grains through meiosis and mitosis.Furthermore,we compare the morphological difference of anthers and pollen grains in both monocot rice and eudicot Arabidopsis thaliana.Additionally,we describe the key genes identified to date critical for rice anther development and pollen formation.Dabing Zhang Xue Luo Lu Zhu 2011Journal of Genetics and Genomics2011,38,9:56
17Spatiotemporal dynamics of impervious surface areas across China during the early 21st century显示文摘China has experienced an unprecedented urbanization and industrialization in the past decades. In this research, we examined the dynamics of construction lands and impervious surface areas (ISA) based on land use/cover change and ISA datasets between 2000 and 2008, which were provided by the national resources and environmental remote sensing information platform. The results indicated that the construction areas and ISA increased by 3468.30 and 2212.24 km 2 /a in this period primarily due to the implementation of national macro-development strategies and fast-growing economy. In 2008, ISA accounted for 0.86% of the total land area in China. Urban land areas increased by 43.46% between 2000 and 2008. The annual growth rate of 1788.22 km 2 /a in this period was 2.18 times that in the 1990s. In particular, urban ISA increased by 53.30% between 2000 and 2008 with an annual growth rate of 1348.85 km 2 /a. During the 8 years, the ISA in China increased rapidly, especially in the Beijing-Tianjin-Tangshan Metropolitan Region, Pearl River Delta, Yangtze River Delta, and the western China region. The increasing ISA may influence potentially water environmental quality in the major basins. In particular, the number of subbasins having ISA of greater than 10% increased considerably, which were primarily distributed in the Haihe River, Yangtze River and Pearl River basins. In 2008, 14.42% of the basin areas were affected by the increased ISA.KUANG WenHui LIU JiYuan ZHANG ZengXiang LU DengSheng XIANG Bao 2013Chinese Science Bulletin2013,58,14:59
18Fast increasing of surface ozone concentrations in Pearl River Delta characterized by a regional air quality monitoring network during 2006–2011显示文摘Based on the observation by a Regional Air Quality Monitoring Network including 16 monitoring stations, temporal and spatial variations of ozone(O3), NO2and total oxidant(Ox) were analyzed by both linear regression and cluster analysis. A fast increase of regional O3concentrations of 0.86 ppbV/yr was found for the annual averaged values from 2006 to 2011 in Guangdong, China. Such fast O3increase is accompanied by a correspondingly fast NOx reduction as indicated by a fast NO2 reduction rate of 0.61 ppbV/yr. Based on a cluster analysis, the monitoring stations were classified into two major categories – rural stations(non-urban) and suburban/urban stations. The O3concentrations at rural stations were relatively conserved while those at suburban/urban stations showed a fast increase rate of 2.0 ppbV/yr accompanied by a NO2 reduction rate of 1.2 ppbV/yr. Moreover, a rapid increase of the averaged O3 concentrations in springtime(13%/yr referred to 2006 level) was observed, which may result from the increase of solar duration, reduction of precipitation in Guangdong and transport from Eastern Central China. Application of smog production algorithm showed that the photochemical O3production is mainly volatile organic compounds(VOC)-controlled. However, the photochemical O3production is sensitive to both NOx and VOC for O3pollution episode. Accordingly, it is expected that a combined NOx and VOC reduction will be helpful for the reduction of the O3 pollution episodes in Pearl River Delta while stringent VOC emission control is in general required for the regional O3 pollution control.Jinfeng Li Keding Lu Wei Lv Jun Li Liuju Zhong Yubo Ou Duohong Chen Xin Huang Yuanhang Zhang 2014Journal of Environmental Sciences2014,26,1:51
19High-dose Iodized Oil Transcatheter Arterial Chemoembolization For Patients with Large Hepatocellular Carcinoma显示文摘AIM:To conduct a randomized trial to evaluate the role ofusing high-dose iodized oil transcatheter arterialchemosmbolization(TACE)in the treatment of largehepatocellular carcinoma(HCC).METHODS:From January 1993 to June 1998,473 patientswith unresectable hepatocellular carcinoma ware divided intotwo groups:216 patients in group A received more than20mL iodized oil during the first TACE treatment;257patients in group B received 5-15mL iodized oil in the sameway.The Child's classification and ICG-R15 for evaluatingthe liver function of the patients ware done before thetreatment.During the TACE procedure the catheters wasinserted into the target artery selectively and the tumorvessels ware demonstrated with contrast medium in thehepatic angiography.The anticancar drugs mixed withiodized oil(Lipiodol)ware Epirubicin and Mitomycin.Ingroup A,112 cases received 20-29mL Lipiodol in the firstprocedure,85 cases 30-39mL,19 cases more than 40mL.The largest dose was 53 mL and the average dose was28.3mL.In group B,119 cases received 5-10mL Lipiodol,138 cases received 11-15mL,and the average dose was11.8mL.RESULTS:High-dose Lipiodol chemoembolization causedtolerable side effects and a little hurt to the liver function inthe patients with Child grade A or ICG-R15<20.But thepatients with child grade B or ICG-R15>20 had higher risk ofliver failure after high-dose TACE.More type Ⅱ and type Ⅱlipiodol accumulations in CT scan after 4 weeks of TACEware seen in the group A patients than those in the group Bpatients(P<0.01).The resection rate and complete tumornecrosis rate in group A ware higher than those of group B(P<0.05).The 1-,2-,3-year survival rates of group Apatients with Child grade A ware 79.2%,51.8% and 34.9%,respectively,better then those of group B(P<0.001).CONCLUSION:High-dose Lipiodol can result in morecomplete tumor necrosis by blocking both arteries and small portal veins of the tumor.High-dose TACE for treatment oflarge and hypervascular hepatocallular carcinoma ispractically acceptable with the better effect than the routinedose.For the patients with large and hypervascular tumor ofChild grade A liver function or ICG-R15 less than 20%,oilychemoembolization with 20-40mL Lipiodol is recommended.Min-Shan Chen Jin-Qing Li Ya-Qi Zhang Yun-Fei Yuan Yong-Ping Guo Xiao-Jun Lin Guo-Hui Lim Department of Hepatobiliary Cancer Center of Sun Yet-sen University of Medical Sciences,Guangzhou 510060,China Li-Xia Lu Wei-Zhang Zhang Department of Radiology Cancer Center of Sun Yet-sen University of Medical Sciences,Guangzhou 510060,China 2002World Journal of Gastroenterology2002,8,1:58
