1Review of risk factors for human echinococcosis prevalence on the Qinghai-Tibet Plateau, China: a prospective for control options显示文摘Objective: Echinococcosis is a major parasitic zoonosis of public health importance in western China. In 2004, the Chinese Ministry of Health estimated that 380,000 people had the disease in the region. The Qinghai-Tibet Plateau is highly co-endemic with both alveolar echinococcosis (AE) and cystic echinococcosis (CE). In the past years, the Chinese government has been increasing the financial support to control the diseases in this region. Therefore, it is very important to identify the significant risk factors of the diseases by reviewing studies done in the region in the past decade to help policymakers design appropriate control strategies. Review: Selection criteria for which literature to review were firstly defined. Medline, CNKI (China National Knowledge Infrastructure), and Google Scholar were systematically searched for literature published between January 2000 and July 2011. Significant risk factors found by single factor and/or multiple factors analysis were listed, counted, and summarized. Literature was examined to check the comparability of the data;age and sex specific prevalence with same data structures were merged and used for further analysis. A variety of assumed social, economical, behavioral, and ecological risk factors were studied on the Plateau. Those most at risk were Tibetan herdsmen, the old and female in particular. By analyzing merged comparable data, it was found that females had a significant higher prevalence, and a positive linearity relationship existed between echinococcosis prevalence and increasing age. In terms of behavioral risk factors, playing with dogs was mostly correlated with CE and/or AE prevalence. In terms of hygiene, employing ground water as the drinking water source was significantly correlated with CE and AE prevalence. For definitive hosts, dog related factors were most frequently identified with prevalence of CE or/and AE;fox was a potential risk factor for AE prevalence only. Overgrazing and deforestation were significant for AE prevalence only. Conclusion: Tibetan herdsmen communities were at the highest risk of echinococcosis prevalence and should be the focus of echinococcosis control. Deworming both owned and stray dogs should be a major measure for controlling echinococcosis;treatment of wild definitive hosts should also be considered for AE endemic areas. Health education activities should be in concert with the local people's education backgrounds and languages in order to be able to improve behaviors. Further researches are needed to clarify the importance of wild hosts for AE/CE prevalence, the extent and range of the impacts of ecologic changes (overgrazing and deforestation) on the AE prevalence, and risk factors in Tibet.Qian Wang Yan Huang Liang Huang Wenjie Yu Wei He Bo Zhong Wei Li Xiangman Zeng Dominique A Vuitton Patrick Giraudoux Philip S Craig Weiping Wu 2014Infectious Diseases of Poverty2014,3,1:35

5Pancreatitis in patients with pancreas divisum:Imaging features at MRI and MRCP显示文摘AIM:To determine the magnetic resonance cholangiopancreatography(MRCP)and magnetic resonance imaging(MRI)features of pancreatitis with pancreas divisum(PD)and the differences vs pancreatitis without divisum.METHODS:Institutional review board approval was obtained and the informed consent requirement was waived for this HIPAA-compliant study.During one year period,1439 consecutive patients underwent successful MRCP without injection of secretin and abdominal MRI studies for a variety of clinical indications using a 1.5 T magnetic resonance scanner.Two experienced radiologists retrospectively reviewed all the studies in consensus.Disputes were resolved via consultation with a third experienced radiologist.The assessment included presence and the imaging findings of PD,pancreatitis,and distribution of abnormalities.The pancreatitis with divisum constituted the study group while the pancreatitis without divisum served as the control group.MRCP and MRI findings were correlated with final diagnosis.Fisher exact tests and Pearson × 2 tests were performed.RESULTS:Pancreatitis was demonstrated at MRCP and MRI in 173 cases(38 cases with and 135 cases without divisum)among the 1439 consecutive cases.The recurrent acute pancreatitis accounted for 55.26%(21 of 38)in pancreatitis patients associated with PD,which was higher than 6.67%(9 of 135)in the control group,whereas the chronic pancreatitis was a dominant type in the control group(85.19%,115 of 135)when compared to the study group(42.11%,16 of 38)(χ 2 = 40.494,P < 0.0001).In cases of pancreatitis with PD,the dorsal pancreatitis accounted for a much higher percentage than that in pancreatitis without PD(17 of 38,44.74% vs 30 of 135,22.22%)(χ 2 = 7.257,P < 0.05).CONCLUSION:MRCP and MRI can depict the features of pancreatitis associated with divisum.Recurrent acute pancreatitis and isolated dorsal involvement are more common in patients with divisum.Deng-Bin Wang Jinxing Yu Ann S Fulcher Mary A Turner 2013World Journal of Gastroenterology2013,19,30:5

8灰鹤在天山木扎提河湿地越冬及行为观察显示文摘于2017年10月—2019年5月,采用直接计数法、瞬时扫描取样法、卫星跟踪和最小凸多边形法(MCP),对新疆阿克苏地区拜城县木扎提河流域灰鹤(Grus grus)的种群特征、活动范围、行为时间分配和行为节律进行调查和分析。结果表明,2019年越冬灰鹤种群数量超过4700只,较2016年增加1倍多,种群发展动态呈上升趋势。灰鹤主要以家庭群为主(63.90%),聚集群次之(28.62%),孤鹤最少(7.48%)。家庭群主要以2成鸟1幼鸟为主(占46.82%),聚集群以5~8只个体为主(占65.91%)。整个越冬期持续140~160 d,灰鹤越冬期活动距离为1058 km,活动区域相对固定,活动区域面积为125 km^2。日活动面积和活动距离随着气温的变化而变化,温度降低,日活动范围和活动距离降低;反之,则增加。因此,活动面积和活动距离呈凹形变化,即先增加(10—11月),再逐渐减少(12—1月),然后增加(2—3月)的变化趋势。取食和警戒是灰鹤的主要越冬行为。灰鹤的46.8%日间时间用于取食,17.8%的日间时间用于警戒,用于休息、走动、理羽和其他行为的日间时间分别占13.4%、11.4%、7.4%和3.2%。日取食高峰呈双凸型,出现在8:00—9:00和17:00—18:00,分别达到57.0%和58.5%。休息高峰出现在11:00—15:00,占24.6%,呈单峰型。研究区灰鹤种群面临着放牧、农耕、天敌、道路车辆、低温和人为驱赶等诸多威胁因素。李军伟 马鸣 孟凡娟 E I Ilyashenko V Yu Ilyashenko O V Belyalov A E Gavrilov S Kh Zaripova N Batbayar 曹垒 2020生态与农村环境学报2020,36,5:4
9Chromodomain-helicase-DNA binding protein 5, 7 and pronecrotic mixed lineage kinase domain-like protein serve as potential prognostic biomarkers in patients with resected pancreatic adenocarcinomas显示文摘Pancreatic cancer is one of the deadliest cancers with a very poor prognosis. Recently, there has been a significant increase in research directed towards identifying potential biomarkers that can be used to diagnose and provide prognostic information for pancreatic cancer. These markers can be used clinically to optimize and personalize therapy for individual patients. In this review, we focused on 3 biomarkers involved in the DNA damage response pathway and the necroptosis pathway: Chromodomainhelicase-DNA binding protein 5, chromodomain-helicaseDNA binding protein 7, and mixed lineage kinase domain-like protein. The aim of this article is to review present literature provided for these biomarkers and current studies in which their effectiveness as prognostic biomarkers are analyzed in order to determine their future use as biomarkers in clinical medicine. Based on the data presented, these biomarkers warrant further investigation,and should be validated in future studies.Crystal S Seldon Lauren E Colbert William A Hall Sarah B Fisher David S Yu Jerome C Landry 2016World Journal of Gastrointestinal Oncology2016,8,4:2

15Durable Asphalt Pavements Are Self Healing显示文摘The traffic volume and the number of heavy vehicles are growing continuously. Considering the continuous traffic flow and the limited time available for road maintenance,it is very important to design a durable pavement system. Asphalt pavements with a healing capability are believed to be very useful since they can extend the pavement service life thanks to rest periods and hot summers. In order to design durable asphalt pavements,research in understanding and upgrading the self-healing capability of bituminous materials in time is of major importance. The self healing capability of bituminous mastic was evaluated in this research with a direct tension healing test. In the test program,different healing times,crack status and modifications were applied. The results indicate that elastic recovery and flow capacity are important factors for the self healing capability of bituminous materials at different crack phases as simulated with the direct tension test.QIU J VAN DE VEN M F C WU S P YU J Y MOLENAAR A A A 2010武汉理工大学学报2010,32,17:2
