1Quantitative analysis of vascular endothelial growth factor, microvascular density and their clinicopathologic features in human hepatocellular carcinoma显示文摘BACKGROUND: Angiogenesis is known to be essential to the survival, growth, invasion, and metastasis of tumor cells. Vascular endothelial growth factor (VEGF) are an important angiogenic factor regulating tumor angiogenesis, but its significance and tumor pathologic features are un- clear in hepatocellular carcinoma (HCC). In the present study, we analyzed expression of tissue VEGF, alteration of microvascular density (MVD) in microvessel angiogenesis, development and metastasis of HCC, and level of serum VEGF in differential diagnosis of benign and malignant liv- er diseases. METHODS: Tumor specimens were prospectively collected from HCC patients undergoing resection. Total RNAs were extracted and the expression levels were detected from different parts of HCC tissues. The cellular distributions of VEGF and MVD of liver tumors and their paracancerous and distal cancerous tissues were investigated by streptavi- din peroxidase (S-P) immunohistochemistry, respectively. The VEGF levels of circulating blood and hepatoma tissues were measured by enzyme-linked immunosorbent assay. RESULTS: The incidence of VEGF expression was 63.9% in HCCs (23/36 cases), 78.3% in non-encapsulated HCCs (18/23), and 90.9% in HCCs with extrahepatic metastasis (10/11), respectively. The VEGF expression was tightly correlated with MVD (P <0.01). The MVD in HCC with metastasis, low differentiation or non-encapsulation was significantly higher than that in HCC with intact capsule, high differentiation, or no metastasis. No significant diffe- rence was found between VEGF, MVD, tumor size, and hepatitis virus infection. The level of total RNA in HCC tis- sues was significantly lower but the VEGF level significantly higher than those in paracancerous or distal cancerous ones (P<0.01). The abnormal expression levels of VEGF in sera of HCC patients were directly correlated with the me- tastasis and recurrence of tumors. CONCLUSION: The high expression of VEGF and abnor- mality of tissue MVD are useful predictors for vascular inva- sion and metastasis of liver tumors.Deng-Fu Yao, Xin-Hua Wu, Yong Zhu, Gong-Sheng Shi, Zhi-Zhen Dong, Deng-Bing Yao, Wei Wu, Li-Wei Qiu and Xian-Yong Meng Nantong, China Research Center of Clinical Molecular Biology , Department of Pathology and Department of Gastroenterology , Affiliated Hos- pital of Nantong University Department of Diagnostics , and Institute of Neurosciences , Nantong University Nantong 226001, China 2005Hepatobiliary & Pancreatic Diseases International2005,4,2:81
2Outline 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

4Dissection of genetic overlap of salt tolerance QTLs at the seedling and tillering stages using backcross introgression lines in rice显示文摘QTLs for salt-tolerance(ST)related traits at the seedling and tillering stages were identified using 99 BC2F8 introgression lines(IL)derived from a cross between IR64(indica)as a recurrent parent and Binam(japonica)from Iran as the donor parent.Thirteen QTLs affecting survival days of seedlings(SDS), score of salt toxicity of leaves(SST),shoot K + concentration(SKC)and shoot Na + concentration(SNC) at the seedling stage and 22 QTLs underlying fresh weight of shoots(FW),tiller number per plant(TN) and plant height(PH)at the tillering stage were identified.Most QTLs detected at the tillering stage showed obvious differential expression to salt stress and were classified into three types based on their differential behaviors.Type I included 11 QTLs which were expressed only under the non-stress condition.Type II included five QTLs expressed in the control and the salt stress conditions,and three of them(QPh5,QPh8 and QTn9)had similar quantity and the same direction of gene effect,suggesting their expression was less influenced by salt stress.Type III included six QTLs which were detectable only under salt stress,suggesting that these QTLs were apparently induced by the stress.Thirteen QTLs affecting trait difference or trait stability of ILs between the stress and non-stress conditions were identified and the Binam alleles at all loci except QPh4,QTn2 and QFw2a decreased trait difference.The three QTLs less influenced by the stress and 13 QTLs affecting trait stability were considered as ST QTLs which contributed to ST.Comparing the distribution of QTLs detected at the seedling and tillering stages,most(69%)of them were genetically independent.Only four were the same or adjacent regions on chromosomes 1,2,8 and 11 harboring ST QTLs detected at the two stages,suggesting that partial genetic overlap of ST across the two stages occurs.It is likely,therefore,to develop ST rice variety for both stages by pyramiding of ST QTLs of different stages or selection against the overlapping QTLs between the two stages via marker-assisted selection(MAS).ZANG JinPing 1 ,SUN Yong 1 ,WANG Yun 1 ,YANG Jing 1 ,LI Fang 1 ,ZHOU YongLi 1 ,ZHU LingHua 1 , Reys JESSICA2,Fotokian MOHAMMADHOSEIN 2,XU JianLong 1&LI ZhiKang 1,2 1Institute of Crop Sciences/National Key Facility for Crop Gene Resources&Genetic Improvement,Chinese Academy of Agricul- tural Sciences,Beijing 100081,China 2International Rice Research Institute,DAPO Box 7777,Metro Manila,Philippines 2008Science China(Life Sciences)2008,51,7:32

8Stenting for symptomatic intracranial arterial stenosis in China:1-year outcome of a multicentre registry study显示文摘background and purpose A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis(ICAS)combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable.However,it remained uncertain whether the low event rate could be of a long term.We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Methods Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid,middle cerebral,intracranial vertebral or basilar arteries combined with poor collaterals were enrolled.Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators.The primary outcome was the rate of 30-day stroke,transient ischaemic attack and death,and 12-month ischaemic stroke within the same vascular territory,haemorrhagic stroke and vascular death after stenting.results From September 2013 to January 2015,300 patients(ages 58.3±9.78 years)were recruited.Among them,159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent.During the 1-year follow-up,25 patients had a primary end point event.The probability of primary outcome at 1 year was 8.1%(95% CI 5.3% to 11.7%).In 76 patients with digital subtraction angiography follow-up,27.6%(21/76)had re-stenosis≥50% and 18.4%(14/76)had re-stenosis≥70%.No baseline characteristic was associated with the primary outcome.Conclusion The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Further randomised trial of comparing individually tailored stenting with best medical therapy is needed.Ning Ma Yong Zhang Jie Shuai Changchun Jiang Qiyi Zhu Kangning Chen Li Liu Baomin Li Xiangqun Shi Lianbo Gao Yajie Liu Feng Wang Yongli Li Tieyan Liu Hongbo Zheng Dapeng Mo Feng Gao Yilong Wang Yongjun Wang Lei Feng Zhongrong Miao 2018Stroke & Vascular Neurology2018,3,3:29
9The application of large volume airgun sources to the onshore-offshore seismic surveys: implication of the experimental results in northern South China Sea显示文摘Onshore-offshore seismic experiments were carried out for the first time in northern South China Sea using large volume airgun sources at sea and seismic stations on land. The experimental results indicate that seismic signals from the new airgun array of R/V Shiyan 2 can be detected as far as 255 km. The signal effective area reaches nearly 50000 km2, which covers Hong Kong and Pearl River Delta. Compared with the old airgun array, the signal amplitude, propagation distance and effective area of the new airgun array have been increased notably, which demonstrates that the upgrade of the airgun source was successful. Comparisons with previous experimental results in other regions show that the shooting effect of the new airgun array is similar to those best airgun sources in the world. Especially, it is a new breakthrough in using the permanent seismic stations onshore to record long distance airgun signals offshore, which has great significance to the realization of the 'seismic radar' concept and the 3D seismic surveys of crustal structure in coastal areas.QIU XueLin CHEN Yong ZHU RiXiang XU HuiLong SHI XiaoBin YE ChunMing ZHAO MingHui XIA ShaoHong 2007Chinese Science Bulletin2007,52,4:27
10Detection of RASSF1A promoter hypermethylation in serum from gastric and colorectal adenocarcinoma patients显示文摘AIM:To evaluate the diagnostic role of serum RASSF1A promoter hypermethylation in gastric and colorectal ad- enocarcinoma. METHODS:Methylation-specific polymerase chain reac- tion (MSPCR) was used to examine the promoter meth- ylation status of the serum RASSF1A gene in 47 gastric adenocarcinoma patients, 45 colorectal adenocarcinoma patients, 60 patients with benign gastrointestinal dis- ease (30 with benign gastric disease and 30 with benign colorectal disease), and 30 healthy donor controls. Apaired study of RASSF1A promoter methylation status in primary tumor, adjacent normal tissue, and postopera- tive serum were conducted in 25 gastric and colorectal adenocarcinoma patients who later were underwent sur- gical therapy. RESULTS:The frequencies of detection of serum RASSF1A promoter hypermethylation in gastric (34.0%) and colorectal (28.9%) adenocarcinoma patients were significantly higher than those in patients with benign gastric (3.3%) or colorectal (6.7%) disease or in healthy donors (0%) (P < 0.01). The methylation status of RASSF1A promoter in serum samples was consistent with that in paired primary tumors, and the MSPCR results for RASSF1A promoter methylation status in paired preoperative samples were consistent with those in postoperative serum samples. The serum RASSF1A promoter hypermethylation did not correlate with patient sex, age, tumor differentiation grade, surgical therapy, or serum carcinoembryonic antigen level. Although the serum RASSF1A promoter hypermethylation frequency tended to be higher in patients with distant metastases, there was no correlation between methylation status and metastasis. CONCLUSION:Aberrant CpG island methylation within the promoter region of RASSF1A is a promising biomark- er for gastric and colorectal cancer.Yu-Cai Wang Zheng-HongYu Chang Liu Li-Zhi Xu Wen Yu Jia Lu Ren-Min Zhu Guo-Li Li Xin-Yi Xia Xiao-Wei Wei Hong-Zan Ji Heng Lu Yong Gao Wei-Min Gao Long-Bang Chen 2008World Journal of Gastroenterology2008,14,19:26
11Three-dimensional hydrodynamic and water quality model for TMDL development of Lake Fuxian,China显示文摘Lake Fuxian is the largest deep freshwater lake in China.Although its average water quality meets Class I of the China National Water Quality Standard(CNWQS),i.e.,GB3838-2002,monitoring data indicate that the water quality approaches the Class II threshold in some areas.Thus it is urgent to reduce the watershed load through the total maximum daily load(TMDL) program.A three-dimensional hydrodynamic and water quality model was developed for Lake Fuxian,simulating flow circulation and pollutant fate and transport.The model development process consists of several steps,including grid generation,initial and boundary condition configurations,and model calibration processes.The model accurately reproduced the observed water surface elevation,spatiotemporal variations in temperature,and total nitrogen(TN),total phosphorus(TP),and chemical oxygen demand(COD) concentrations,suggesting a reasonable numerical representation of the prototype system for further TMDL analyses.The TMDL was calculated using two interpretations of the water quality standards for Class I of the CNWQS based on the maximum instantaneous surface and annual average surface water concentrations.Analysis of the first scenario indicated that the TN,TP and COD loads should be reduced by 66%,68% and 57%,respectively.Water quality was the highest priority;however,local economic development and cost feasibility for load reduction can pose significant issues.In the second interpretation,the model results showed that,under the existing conditions,the average water quality meets the Class I standard and therefore load reduction is unnecessary.Future studies are needed to conduct risk and cost assessments for realistic decision-making.Lei Zhao Xiaoling Zhang Yong Liu Bin He Xiang Zhu Rui Zou Yuanguan Zhu 2012Journal of Environmental Sciences2012,24,8:25
12Surveillance, epidemiology, and pathogen spectrum of hand, foot, and mouth disease in mainland of China from 2008 to 2017显示文摘Hand,foot and mouth disease(HFMD)was reported in May 2,2008 to be the 38th legally notifiable disease in China's National Notifiable Disease Reporting and Surveillance System.In order to solve the infection,an extensive three-level HFMD surveillance laboratory network was established.In this study,the framework of that network is assessed and the incidence of HFMD in China from 2008 to 2017 is reported using a descriptive epidemiologic method.During these 10 years,a series of techniques have been widely applied in all the network laboratories.Using information and material obtained from the network,a virus bank and database containing 18,238 viruses were established.Nationally,18,184,834 HFMD cases,including 152,436 severe cases and 3633 fatal cases,were reported in mainland of China.The average annual incidence in the population was 133.99/100,000 people,with a maximum incidence of 205.06/100,000 people in 2014.The incidence and mortality rates of HFMD were the highest in children aged 1–2 years.The numbers of reported cases fluctuated,with a high incidence observed every 2 years.An overall increase in the number of reported cases was also observed throughout the study period.Despite this,the incidence of severe cases and the mortality rate have been decreasing.High-risk regions are located in southern,eastern,and central China.Two peaks of HFMD infection cases were observed annually except for Northeast China.Different proportions of enterovirus serotypes were observed during the studied years.The predominant enterovirus varies from year to year,but the disease severity is always closely related to the specific serotype.EV-A71 is the dominant serotype associated with severe and fatal cases,with constituent ratios of 70.03%and 92.23%,respectively.The studied highly sensitive and efficient surveillance network provides information that is critical for prevention and control of the disease.It is extremely necessary and important to continuously conduct extensive virological surveillance for HFMD.Tianjiao Ji Taoli Han Xiaojuan Tan Shuangli Zhu Dongmei Yan Qian Yang Yang Song Aili Cui Yan Zhang Naiying Mao Songtao Xu Zhen Zhu Dandan Niu Yong Zhang Wenbo Xu 2019Biosafety and Health2019,1,1:26
13Effects of the two-step ageing treatment on the microstructure and properties of 7B04 alloy pre-stretched thick plates显示文摘The effects of the two-step ageing parameters (temperature and time) on the mechanical properties and electrical conductivity of 7B04 (Al-Zn-Mg-Cu) pre-stretched thick plates were studied. The results reveal that the initial T1 ageing contributes a major increase of the tensile strength, and the 0.2% proof stress value reaches 482 MPa after ageing for 7 h at 115°C. Behavioral differences in the tensile properties of the alloy after the two-step ageing treatment were less with the first-step ageing at 115°C for different time periods (7, 14, and 21 h). The effects of the second ageing parameters on the properties and microstructure of the 7B04 alloy were remarkable. TEM analysis of the samples aged at Temper I (7 h at 115°C + 12 h at 160°C) and Temper II (7 h at 115°C + 16 h at 165°C) indicates that two kinds of phases, i.e. η′ and η phases, precipitate from the matrix and efficiently improve the tensile strength of the alloy, and the grain boundary precipitates are coarse and discrete. There are obvious precipitate free zones (PFZs) along the grain boundary in the microstructure of the alloy after the two-step ageing treatment.LI Zhihui XIONG Baiqing ZHANG Yong 'an ZHU Baohong WANG Feng LIU Hongwei 2007Rare Metals2007,26,3:24
14Furazolidone-based triple and quadruple eradication therapy for Helicobacter pylori infection显示文摘AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori(H. pylori) in a multi-center randomized controlled trial.METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole(10 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole(10 mg), bismuth(220 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According tothe per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. The number of adverse events was 15(8.3%), 16(8.9%), 15(8.3%) and 17(9.4%) in Groups 1, 2, 3 and 4, respectively, including dizziness, vomiting, diarrhea, nausea, skin rash, itchy skin, and malaise. The symptoms were relieved without special treatment in all of the patients.CONCLUSION: Both 7- and 10-d quadruple furazolidone-based therapies achieve satisfactory H. pylori eradication rates.Yong Xie Yin Zhu Hong Zhou Zhi-Fa Lu Zhen Yang Xu Shu Xiao-Bai Guo Hui-Zhen Fan Jian-Hua Tang Xue-Ping Zeng Jian-Bo Wen Xiao-Qing Li Xing-Xing He Jiu-Hong Ma Dong-Sheng Liu Cai-Bin Huang Ning-Jian Xu Nong-Rong Wang Nong-Hua Lu 2014World Journal of Gastroenterology2014,20,32:24
15Molecular Epidemiological Analysis of Echovirus 19 Isolated From an Outbreak Associated With Hand, Foot, and Mouth Disease (HFMD) in Shandong Province of China显示文摘Objective To elucidate the genetic characterization and molecular epidemiological features of Echovirus 19(E19)isolates collected from an outbreak associated with hand,foot and mouth disease(HFMD)in Tai'an city of Shandong Province of China from July to September,2003.Methods Thirty seven Echovirus 19 isolates were isolated from stool specimens and throat swabs collected during the outbreak,then major capsid(VP1)genomic sequence was determined,and phylogenetic tree was done based on the VP1 sequences among these 37 and other E19 viruses deposited in the Genbank.Also a representative strain named CHN-SD03-TN12 was selected for sequencing of 5'-untranslated regions(5'-UTR).Results The identity rate was about 98.9%-100% among all these 37 E19 viruses.The genetic relationships between these 37 E19 isolates and other strains reported were also depicted.The identity rate was about 78.4%-78.9% compared with E19 reference strain Burke.The substitutions in the sequence of 5'-UTR resulted in changes in the conjectural properties of 5'-UTR of E19 viruses.Conclusion The genetic features of E19 viruses isolated during the outbreak in Shandong Province in 2003 may be associated with a genetic and antigenic drift that changes the virulence of the Shandong isolates,but the molecular changes in Shandong E19 viruses contributing to their phenotype remain to be further illuminated.However,the sequences described in this paper substantiate the changes taken place in capsid VP1 and 5'UTR regions.These substitutions may contribute to their tropism and virulence,and play a significant role in pathogenesis and clinical manifestations of the disease.ZHEN ZHU WEN-BO XU AI-QIANG XU HAI-YAN WANG YONG ZHANG LI-ZHI SONG Hui-LiYANG YANLI FENGJI 2007Biomedical and Environmental Sciences2007,20,4:22
