1Risk assessment of heavy metals in soils and vegetables around nonferrous metals mining and smelting sites,Baiyin,China显示文摘A field survey was conducted to investigate the metal and arsenic contamination in soils and vegetables on four villages (Shuichuan (SCH), Beiwan (BWA), Dongwan (DWA) and Wufe (WFE)) located along, Baiyin, China, and to evaluate the possible health risks to local population through foodchain. Results show that the most significantly contaminated soils occurred upstream at SCH where Cd, Cu and As concentrations exceeded maximum allowable concentrations for Chinese agricultural soil. Further downstream the degree of contamination semi-systematically decreased in concentrations of metal. Generally, the leafy vegetables were more heavily contaminated than non-leafy vegetables. Chinese cabbage is the most severely contaminated, the concentrations of Cd exceeded the maximum permit levels (0.05 mg/kg) by 4.5 times. Bio-accumulate factor also shows that an entry of Cd to food chain plants is the greatest potential. Furthermore, the estimated daily intake amounts of the considered toxic elements (Cd, Pb and Cu) from the vegetables grown at SCH and BWA and DWA have exceeded the recommended dietary allowance levels. Thus, the vegetables grown in three villages above, which affected by Baiyin mining and smelting have a health hazard for human consumption.LI Yu WANG Yan-bin GOU Xin SU Yi-bing WANG Gang 2006Journal of Environmental Sciences2006,18,6:84

3Outline of the Report on Cardiovascular Disease in China,2010显示文摘Major and profound changes have taken place in China over the past 30 years.Rapid socioeconomic progress has exerted a great impact on lifestyle,ranging from food,clothing,working and living conditions,and means of transportation to leisure activities and entertainment.At the same time,new health problems have emerged,and health services are facing new challenges.Presently,cardiovascular diseases (CVD) are among the top health problems of the Chinese people,and pose a serious challenge to all engaged in the prevention and control of these diseases.An epidemic of CVD in China is emerging as a result of lifestyle changes,urbanization and longevity.Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures.Since 2005,guided by the Bureau of Disease Prevention of the Ministry of Health of the People's Republic of China and the National Center for Cardiovascular Diseases of China,nationwide experts in the fields of epidemiology,clinical medicine and health economics in the realms of CVD,cerebrovascular disease,diabetes and chronic kidney disease,completed the Report on Cardiovascular Diseases in China every year.The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD.In addition,as the report is authoritative,representative and readable,it will become an information platform in the CVD field and an important reference book for government,academic institutes,medical organizations and clinical physicians.This publication is expected to play a positive role in the prevention and control of CVD in China.We present an abstract from the Report on Cardiovascular Diseases in China (2010),including trends in CVD,morbidity and mortality of major CVDs,up-to-date assessment of risk factors,as well as health resources for CVD,and a profile of medical expenditure,with the aim of providing evidence for decision-making in CVD prevention and control programs in China,and of delivering the most authoritative information on CVD prevention and control for all citizens.HUSheng Shou KONG Ling Zhi GAO Run Lin ZHU Man Lu WANG Wen WANG Yong Jun WU Zhao Su CHEN Wei Wei LIU Ming Bo For the editorial board 2012Biomedical and Environmental Sciences2012,25,3:93
4Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT.WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin 2014Science China Earth Sciences2014,57,1:106
5Clinicopathological characteristics in the differential diagnosis of hepatoid adenocarcinoma:A literature review显示文摘Hepatoid adenocarcinoma (HAC) is a rare but important special type of extrahepatic adenocarcinoma with clinicopathological presentation mimicking hepatocellular carcinoma (HCC), and prompt and correct diagnosis can be a challenge, especially in endemic areas with a high incidence of HCC. To date, HAC has only been reported in case series or single case reports, so we aimed to review the clinicopathological characteristics of HAC to obtain a more complete picture of this rare form of extrahepatic adenocarcinoma. All the articles about HAC published from 2001 to 2011 were reviewed, and clinicopathological findings were extracted for analysis. A late middle-aged male with high serum α-fetoprotein and atypical image finding of HCC should raise the suspicion of HAC, and characteristic pathological immunohistochemical stains can help with the differential diagnosis. Novel immunohistochemical markers may be useful to clearly differentiate HAC from HCC. Once metastatic HAC is diagnosed, the primary tumor origin should be identified for adequate treatment. The majority of HAC originates from the stomach, so panendoscopy should be arranged first.Jiann-Sheng Su Yu-Tso Chen Ren-Ching Wang Chun-Ying Wu Shou-Wu Lee Teng-Yu Lee 2013World Journal of Gastroenterology2013,19,3:75

8The Beishan underground research laboratory for geological disposal of high-level radioactive waste in China:Planning, site selection,site characterization and in situ tests显示文摘With the rapid development of nuclear power in China, the disposal of high-level radioactive waste(HLW) has become an important issue for nuclear safety and environmental protection. Deep geological disposal is internationally accepted as a feasible and safe way to dispose of HLW, and underground research laboratories(URLs) play an important and multi-faceted role in the development of HLW repositories. This paper introduces the overall planning and the latest progress for China's URL. On the basis of the proposed strategy to build an area-specific URL in combination with a comprehensive evaluation of the site selection results obtained during the last 33 years, the Xinchang site in the Beishan area,located in Gansu Province of northwestern China, has been selected as the final site for China's first URL built in granite. In the process of characterizing the Xinchang URL site, a series of investigations,including borehole drilling,geological mapping, geophysical surveying,hydraulic testing and in situ stress measurements, has been conducted. The investigation results indicate that the geological,hydrogeological, engineering geological and geochemical conditions of the Xinchang site are very suitable for URL construction. Meanwhile, to validate and develop construction technologies for the Beishan URL, the Beishan exploration tunnel(BET), which is a 50-m-deep facility in the Jiujing sub-area, has been constructed and several in situ tests, such as drill-and-blast tests, characterization of the excavation damaged zone(EDZ), and long-term deformation monitoring of surrounding rocks, have been performed in the BET. The methodologies and technologies established in the BET will serve for URL construction.According to the achievements of the characterization of the URL site, a preliminary design of the URL with a maximum depth of 560 m is proposed and necessary in situ tests in the URL are planned.Ju Wang Liang Chen Rui Su Xingguang Zhao 2018Journal of Rock Mechanics and Geotechnical Engineering2018,10,3:62
9ECharts: A declarative framework for rapid construction of web-based visualization显示文摘While there have been a dozen of authoring systems and programming toolkits for visual design and development,users who do not have programming skills,such as data analysts or interface designers,still may feel cumbersome to efficiently implement a web-based visualization.In this paper,we present ECharts,an open-sourced,web-based,cross-platform framework that supports the rapid construction of interactive visualization.The motivation is driven by three goals:easy-touse,rich built-in interactions,and high performance.The kernel of ECharts is a suite of declarative visual design language that customizes built-in chart types.The underlying streaming architecture,together with a high-performance graphics renderer based on HTML5 canvas,enables the high expandability and performance of ECharts.We report the design,implementation,and applications of ECharts with a diverse variety of examples.We compare the utility and performance of ECharts with C3.js,HighCharts,and Chart.js.Results of the experiments demonstrate the efficiency and scalability of our framework.Since the first release in June 2013,ECharts has iterated 63 versions,and attracted over 22,000 star counts and over 1700 related projects in the GitHub.ECharts is regarded as a leading visualization development tool in the world,and ranks the third in the GitHub visualization tab.Deqing Li Honghui Mei Yi Shen Shuang Su Wenli Zhang Junting Wang Ming Zu Wei Chen 2018Visual Informatics2018,2,2:69
10Potential role of Th17 cells in the pathogenesis of inflammatory bowel disease显示文摘The etiopathology of inflammatory bowel disease(IBD)remains elusive.Accumulating evidence suggests that the abnormality of innate and adaptive immunity responses plays an important role in intestinal inflammation.IBD including Crohn's disease(CD)and ulcerative colitis(UC)is a chronic inflammatory disease of the gastrointestinal tract,which is implicated in an inappropriate and overactive mucosal immune response to luminalflora.Traditionally,CD is regarded as a Th1-mediated inflammatory disorder while UC is regarded as a Th2-like disease.Recently,Th17 cells were identif ied as a new subset of T helper cells unrelated to Th1 or Th2 cells,and several cytokines [e.g.interleukin(IL)-21,IL-23] are involved in regulating their activation and differentiation.They not only play an important role in host defense against extracellular pathogens,but are also associated with the development of autoimmunity and inflammatory response such as IBD.The identif ication of Th17 cells helps us to explain some of the anomalies seen in the Th1/Th2 axis and has broadened our understanding of the immunopathological effects of Th17 cells in the development of IBD.Zhan-Ju Liu Praveen K Yadav Jing-Ling Su Jun-Shan Wang Ke Fei 2009World Journal of Gastroenterology2009,15,46:44

12Shear-wave splitting beneath Yunnan area of Southwest China显示文摘Systematic analyses of seismic data recorded by the Yunnan regional seismograph network reveal significant crustal and upper mantle anisotropy.Splitting of the S phase of local earthquakes and teleseismic SKS,PKS,and SKKS phases indicates time-delays from 1.60 ms/km to 2.30 ms/km in the crust,and from 0.55 s to 1.65 s in the upper mantle which corresponds to an anisotropic layer with a thickness about between 55-165 km.The polarization orientations of fast shear waves in the crust are complicated with a predominantly north-south direction,and the mantle anisotropy has a nearly west-east direction.Our results show different deformation styles and mechanisms exist between the crust and upper mantle.Yutao Shi Yuan Gao Youjin Su Qiong Wang 2012Earthquake Science2012,25,1:46
13Randomized controlled trial of uncut Roux-en-Y vs Billroth Ⅱ reconstruction after distal gastrectomy for gastric cancer: Which technique is better for avoiding biliary reflux and gastritis?显示文摘AIM To identify which technique is better for avoiding biliary reflux and gastritis between uncut Roux-en-Y and Billroth Ⅱ reconstruction. METHODS A total of 158 patients who underwent laparoscopyassisted distal gastrectomy for gastric cancer at the First Hospital of Jilin University(Changchun, China) between February 2015 and February 2016 were randomized into two groups: uncut Roux-en-Y(group U) and Billroth II group(group B). Postoperative complications and relevant clinical data were compared between the two groups. RESULTS According to the randomization table, each group included 79 patients. There was no significant difference in postoperative complications between groups U and B(7.6% vs 10.1%, P = 0.576). During the postoperative period, group U stomach p H values were lower than 7 and group B p H values were higher than 7. After 1 year of follow-up, group B presented a higher incidence of biliary reflux and alkaline gastritis. However, histopathology did not show a significant difference in gastritis diagnosis(P = 0.278), and the amount of residual food and gain of weight between the groups were also not significantly different. At 3 mo there was no evidence of partial recanalization of uncut staple line, but at 1 year the incidence was 13%. CONCLUSION Compared with Billroth II reconstruction, uncut Rouxen-Y reconstruction is secure and feasible, and can effectively reduce the incidence of alkaline reflux, residual gastritis, and heartburn. Despite the incidence of recanalization, uncut Roux-en-Y should be widely applied.Dong Yang Liang He Wei-Hua Tong Zhi-Fang Jia Tong-Rong Su Quan Wang 2017World Journal of Gastroenterology2017,23,34:43
14Effects of field application of phosphate fertilizers on the availability and uptake of lead, zinc and cadmium by cabbage (Brassica chinensis L.) in a mining tailing contaminated soil显示文摘A field trial was conducted to evaluate the reduction of bioavailability of heavy metals including lead (Pb), zinc (Zn) and cadmium (Cd) in a soil contaminated by mining tailings in Shaoxing, Zhejiang, China. Three commercial phosphate (P) fertilizers including phosphate rock (PR), calcium magnesium phosphate (CMP), and single superphosphate (SSP) were applied to the plot at three P application rates, 50, 300, and 500 g/m2 with 9 treatments and control (CK). Plants, water soluble and exchangeable (WE) extraction procedure and modified toxicity characteristic leaching procedure (TCLP) were employed. It was found that the addition of all three P fertilizers significantly decreased WE Pb (22.0%-81.4%), Cd (1.5%-30.7%) and Zn (11.7%-75.3%, exception of SSP treatments with no significant difference) and TCLP Pb concentration (27.1%-71.2%), compared with the control, leading to reduced uptake of Pb (16.0%-58.0%), Cd (16.5%-66.9%) and Zn (1.2%-73.2%) by cabbage (Brassica chinensis L.). It was suggested that P fertilizers induced immobilization of heavy metals such as Pb, Cd, and Zn. CMP provided the most effective method of reducing metal toxicity, mobility, and phytoavailability. At the P application rate of 300 g/m2, CMP would be cost-effective to decrease WE Pb, Zn, and Cd concentration from 666 to 137 mg/kg, from 31.2 to 8.71 mg/kg, and from 1.69 to 1.36 mg/kg, respectively. SSP was more effective in reducing Pb bioavailability than PR but had variable effects on Zn bioavailability. Cd uptake by cabbage was negatively correlated with soil pH rather than with WE or TCLP, indicating that Cd uptake by cabbage was a complex process. It should be careful to evaluate the impact of phosphate application on Cd availability in soil.Biling WANG Qiufeng SU 2008Journal of Environmental Sciences2008,20,9:39
15Relationship between phenotypes of cell-function differentiation and pathobiological behavior of gastric carcinomas显示文摘AIM To reveal the correlation between thefunctional differentiation phenotypes of gastriccarcinoma cells and the invasion and metastasisby a new way of cell-function classification.METHODS Surgically resected specimens of361 gastric carcinomas (GC) were investigatedwith enzyme-, mucin-, and tumor-related markerimmunohistochemist ry. According to thedirection of cell-function differentiation,stomach carcinomas were divided into fivefunctionally differentiated types.iation type (AFDT): there were 82 (22.7%)patients including 76 (92.7%) aged 45 years.Sixty-nine (84.1%) cases belonged to theintestinal type. Thirty-eight (46.3%) expressedCD44v6 and 9 (13.6%) of 66 male patientsdeveloped liver metastasis. The 5-year survivalrate of patients in this group (58.5%) was higherMucin secreting function differentiation type(MSFDT): 54 (15%) cases. Fifty-three (98.1%)tumors had penetrated the serosa, 12 (22.2%)expressed ER and 22 (40.7%) expressedCD44v6. The postoperative 5-year survival ratefunction differentiation type (AMPFDT): therewere 180 (49.9%) cases, including 31 (17.2%)aged yanger than 45 years. The tumor was morecommon in women (62, 34.4%,) and expressedmore frequently estrogen receptors (ER) ( 129,81.7%) than other types (P<0.01). Ovarymetastasis was found in 12 (19.4%) out of 62female subjects. The patients with this type GChad the lowest 5-year survival rate (24.7%)differentiation type (SFDT): 13 (3.6%) cases.Nine (69.2%) tumors of this type derived fromAPUD system, the other 4 (30.7%) were ofdifferent histological differentiation. Sixty percent of the patients survived at least five years.(8.9%) cases. Nineteen (59.4%) cases hadlymph node metastases but no one with liver orovary metastasis. The 5-year survival rate was28.1%.CONCLUSION This new cell-functionclassification of GC is helpful in indicating thecharacteristics of invasion and metastasis of GCwith different cell-function differentiationphenotypes. Further study is needed to disclosethe correlation between the cell-functionaldifferentiation phenotypes and the relevantgenotypes and the biological behavior of gastriccarcinoma.Yan Xin Xiao Ling Li Yan Ping Wang Su Min Zhang Hua Chuan Zheng Dong Ying Wu Yin Chang Zhang The Fourth Laboratory of Cancer Institute, China Medical University, Shenyang 110001, Liaoning Province, China 2001World Journal of Gastroenterology2001,7,1:38
16The Sequence of Magmatic-Tectonic Events and Orogenic Processes of the Yanshan Belt, North China显示文摘This paper emphasizes that the interactive constraints of geology and isotopic dating is the best approach to construct the geological event sequence, and has compiled 106 data of reasonable isotopic ages for the igneous rocks of the Yanshan belt. We propose a sequence of mgmatic-tectonic events in the Jurassic-Cretaceous Yanshan orogen of North China. Five orogenic episodes are divided, (1) pre-and initial orogenic episode (Early Jurassic); (2) early orogenic episode (Middle Jurassic); (3) peak orogenic episode (Late Jurassic); (4) late orogenic episode (early Early Cretaceous),and (5) post-orogenic episode. Each episode is a short cycle, all of the orogenic processes construct a longer cycle, and they, in general, followed a counter-clockwise (ccw) PTt path. Finally, it is suggested that the Yanshanian movement was so intensive that the magmatism and tectonic deformation had involved all the lithosphere thickness and the lateAchaean-formed cratonic lithosphere had been significantly reworked.DENG Jinfu, SU Shangguo, MO Xuanxue, ZHAO Guochun, XIAO Qinghiu, JI Guangyi,QIU Ruizhao, ZHAO Hailing, LUO Zhaohua, WANG Yang and LIU Cui China University of Geosciences, Beijing 100083 and Key Laboratory of Lithospheric Tectonics and Lithoprobe Techniques, Ministry of Education of China 2004Acta Geologica Sinica(English Edition)2004,78,1:35

19Discovery of the eclogite and its petrography in the Northern Dabie Mountain显示文摘Eclogite from the Northern Dabie Mountain is a new finding by the authors. These eclogites in foliated perdotite are enveloped by banded gneiss and occur in the mafic-ultramafic rock belt. They are mainly composed of omphacite, garnet, diopside, orthopyroxene, amphibole, plagioclase and magnetite, and a small amount of rutile, spinel, olivin and 鏾rundum. The mineral association of peak metamorphism of the eclogite is omphacite+garnet+rutile. The existence of eclogite in the Northern Dabie Mountain implies that there was an eclogitic metamorphism prior to the granulitic facies one in the mafic-ultramafic rock belt.XU Shutong LIU Yican SU Wen WANG Rucheng JIANG Laili WU Weiping 2000Chinese Science Bulletin2000,45,3:39
20Inhibition of Dual Specific Oncolytic Adenovirus on Esophageal Cancer via Activation of Caspases by a Mitochondrial-dependent Pathway显示文摘We investigated the anti-tumor effects of dual cancer specific-oncolytic adenovirus Ad-VP on esophageal cancer(EC).The anti-tumor activity of Ad-VP was compared with that of the control recombinant adenoviruses(Ad-GP,Ad-Apoptin,Ad-EGFP) in human esophageal cancer cell EC-109 and human normal liver cell L02 in vitro.In 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assays,the growth of EC-109 cells was slightly inhibited by Ad-GP,Ad-Apoptin and Ad-EGFP.However,Ad-VP induced a significant cytotoxic effect.Infection of EC-109 cells with Ad-VP resulted in a significant induction of apoptosis of them in vitro,detected by 4',6-diamidino-2-phenylindole(DAPI) or acridine orange and ethidium bromide staining.The results of Western blot and flow cytometric assay indicate the loss of mitochondrial membrane potential(ΔΨ m),the release of cytochrome c and the activation of caspase-3,6 and 7 in Ad-VP infected EC-109 cells.In contrast,all these assays show almost no effects of the recombinant adenoviruses on L02 cells.These results demonstrate that the treatment of tumors with Ad-VP selectively inhibits tumor growth and induces apoptosis of esophageal cancer cells.Ad-VP may provide a novel and powerful strategy for cancer gene therapy.SU Jia-qiang CHI Bao-rong LI Xiao LIU Lei LIU Li-ming QI Yan-xin WANG Zhuo-yue JIN Ning-yi 2012Chemical Research in Chinese Universities2012,28,3:38
