3H pylori and gastric cancer: Shifting the global burden显示文摘Infection with H pylori leads to a persistent chronic in?ammation of the gastric mucosa, thereby increasing the risk of distal gastric adenocarcinoma. Numerous studies have determined a clear correlation between H pylori infection and the risk of gastric cancer; however, general eradication is not recommended as cancer prophylaxis and time points for treatment remain controversial in different areas of the world. Prevalence rates in Western countries are decreasing, especially in younger people (< 10%); and a decline in distal gastric adenocarcinoma has been observed. Risk groups in Western countries still show considerably higher risk of developing cancer, especially in patients infected with cagA + strains and in persons harboring genetic polymorphism of the IL-1B promoter (-511T/T) and the corresponding IL-1 receptor antagonist (IL-1RN*2). Thus, general eradication of all infected persons in Western countries not recommended and is limited to risk groups in order to achieve a risk reduction. In contrast, infection rates and cancer prevalence are still high in East Asian countries. A prevention strategy to treat infected persons may avoid the development of gastric cancer to a large extent and with enormous clinical importance. However, studies in China and Japan indicate that prevention of gastric cancer is effective only in those patients that do not display severe histological changes such as atrophy and intestinal metaplasia. Thus, prophylactic strategies to prevent gastric cancer in high risk populations such as China should therefore especially aim at individuals now at younger age when the histological alterations caused by the bacterial infection was still reversible. In countries with a low prevalence of gastric cancer, risk groups carrying cagA+ strains and IL-1 genetic polymorphisms should be identi?ed and treated.Christian Prinz Susanne Schwendy Petra Voland 2006World Journal of Gastroenterology2006,12,34:33

5Endoscopic ultrasound guided radiofrequency ablation,for pancreatic cystic neoplasms and neuroendocrine tumors显示文摘AIM: To outline the feasibility, safety, adverse events and early results of endoscopic ultrasound(EUS)-radiofrequency ablation(RFA) in pancreatic neoplasms using a novel probe. METHODS: This is a multi-center, pilot safety feasibility study. The intervention described was radiofrequency ablation(RF) which was applied with an innovative monopolar RF probe(1.2 mm Habib EUS-RFA catheter) placed through a 19 or 22 gauge fine needle aspiration(FNA) needle once FNA was performed in patients with a tumor in the head of the pancreas. The HabibTM EUSRFA is a 1 Fr wire(0.33 mm, 0.013') with a working length of 190 cm, which can be inserted through the biopsy channel of an echoendoscope. RF power is applied to the electrode at the end of the wire to coagulate tissue in the liver and pancreas.RESULTS: Eight patients [median age of 65(range 27-82) years; 7 female and 1 male] were recruited in a prospective multicenter trial. Six had a pancreatic cysticneoplasm(four a mucinous cyst, one had intraductal papillary mucinous neoplasm and one a microcystic adenoma) and two had a neuroendocrine tumors(NET) in the head of pancreas. The mean size of the cystic neoplasm and NET were 36.5 mm(SD ± 17.9 mm) and 27.5 mm(SD ± 17.7 mm) respectively. The EUSRFA was successfully completed in all cases. Among the 6 patients with a cystic neoplasm, post procedure imaging in 3-6 mo showed complete resolution of the cysts in 2 cases, whilst in three more there was a 48.4% reduction [mean pre RF 38.8 mm(SD ± 21.7 mm) vs mean post RF 20 mm(SD ± 17.1 mm)] in size. In regards to the NET patients, there was a change in vascularity and central necrosis after EUS-RFA. No major complications were observed within 48 h of the procedure. Two patients had mild abdominal pain that resolved within 3 d. CONCLUSION: EUS-RFA of pancreatic neoplasms with a novel monopolar RF probe was well tolerated in all cases. Our preliminary data suggest that the procedure is straightforward and safe. The response ranged from complete resolution to a 50% reduction in size.Madhava Pai Nagy Habib Hakan Senturk Sundeep Lakhtakia Nageshwar Reddy Vito R Cicinnati Iyad Kaba Susanne Beckebaum Panagiotis Drymousis Michel Kahaleh William Brugge 2015World Journal of Gastrointestinal Surgery2015,7,4:23

11成年人身体活动变化过程的理论建构及其测量工具的研究显示文摘介绍了一个近期由中国和德国锻炼心理学家们共同构建的、针对成年人身体活动变化过程的理论——'从无活动到保持活动的四步骤模型'(Four Steps fromInactivity to Activi-ty;FIT模型),并初步检验了基于FIT模型编制的测量工具——《成年人身体活动调查问卷》。研究认为,FIT模型系统地描述了中德两国成年人身体活动变化过程的阶段特点,以及与行为阶段转化密切相关的健康体质因素和社会心理环境的影响因素。所用调查问卷在两国成年人样本中均具有良好的心理测量学信、效度水平。今后可以在此基础上进一步开展系列实证性研究,以推动FIT模型在中德两国的发展。段艳平 韦晓娜 WALTER Brehm HELMUT Strobl 黄志剑 姒刚彦 SUSANNE Tittlbach 2011体育科学2011,31,7:10
12Spatial epidemiology of diabetes: Methods and insights显示文摘Diabetes mellitus(DM)is a growing epidemic with global proportions.It is estimated that in 2019,463 million adults aged 20-79 years were living with DM.The latest evidence shows that DM continues to be a significant global health challenge and is likely to continue to grow substantially in the next decades,which would have major implications for healthcare expenditures,particularly in developing countries.Hence,new conceptual and methodological approaches to tackle the epidemic are long overdue.Spatial epidemiology has been a successful approach to control infectious disease epidemics like malaria and human immunodeficiency virus.The implementation of this approach has been expanded to include the study of non-communicable diseases like cancer and cardiovascular diseases.In this review,we discussed the implementation and use of spatial epidemiology and Geographic Information Systems to the study of DM.We reviewed several spatial methods used to understand the spatial structure of the disease and identify the potential geographical drivers of the spatial distribution of DM.Finally,we discussed the use of spatial epidemiology on the design and implementation of geographically targeted prevention and treatment interventions against DM.Diego F Cuadros Jingjing Li Godfrey Musuka Susanne F Awad 2021World Journal of Diabetes2021,12,7:10
13Mechanisms of intrahepatic triglyceride accumulation显示文摘Hepatic steatosis defined as lipid accumulation in hepatocytes is very frequently found in adults and obese adolescents in the Western World. Etiologically, obesity and associated insulin resistance or excess alcohol intake are the most frequent causes of hepatic steatosis. However, steatosis also often occurs with chronic hepatitis C virus(HCV) infection and is also found in rare but potentially life-threatening liver diseases of pregnancy. Clinical significance and outcome of hepatic triglyceride accumulation are highly dependent on etiology and histological pattern of steatosis. This review summarizes current concepts of pathophysiology of common causes of hepatic steatosis, including non-alcoholic fatty liver disease(NAFLD), alcoholic fatty liver disease, chronic HCV infections, drug-induced forms of hepatic steatosis, and acute fatty liver of pregnancy. Regarding the pathophysiology of NAFLD, this work focuses on the close correlation between insulin resistance and hepatic triglyceride accumulation, highlighting the potential harmful effects of systemic insulin resistance on hepatic metabolism of fatty acids on the one side and the role of lipid intermediates on insulin signalling on the other side. Current studies on lipid droplet morphogenesis have identified novel candidate proteins and enzymes in NAFLD.Claudia Ress Susanne Kaser 2016World Journal of Gastroenterology2016,22,4:10
14成年人身体活动变化的理论建构、问卷发展及系列实证研究——一项中德合作科研课题显示文摘从以下几方面详细介绍一项为期3年(2009-2011)的中德合作科研课题——'健康行为和健康资源的身体活动:阶段、决定因素和效益'。(1)阐述'从无活动到保持活动的4步骤(FIT)模型'的理论建构。(2)以FIT模型为基础,检验中文版和德文版'成年人身体活动调查问卷'的信效度水平。(3)以中德成年人为研究被试,考查FIT模型的效度。研究结果表明:FIT模型能够较准确地描述中德两国成年人身体活动变化过程的阶段性特征及其影响因素,该模型的阶段算法效度、诊断功能及服务干预的功能均得到初步验证,为未来进行基于FIT模型的阶段匹配干预研究提供了理论依据和实证支持。段艳平 WALTER BREHM HELMUT STROBL 黄志剑 姒刚彦 SUSANNE TITTLBACH 2012天津体育学院学报2012,27,3:9
15四价人乳头瘤病毒疫苗的效力和效果:10年真实世界研究的系统综述显示文摘预防性人乳头瘤病毒(HPV)疫苗接种计划是全球性的重要公共卫生措施。本文分析了四价HPV疫苗对HPV感染和相关疾病的全球影响。系统检索PubMed和Embase数据库2007年1月至2016年2月发表的四价HPV疫苗对感染、肛门生殖器疣、宫颈癌或癌前病变的效力或效果的观察性研究的报道。十年来,真实世界环境中HPV疫苗效果越来越明显,尤其在疫苗接种率较高国家中那些在HPV暴露发生之前接种的女孩。据报道,疫苗可使HPV6、11、16、18感染最多减少约90%,生殖器疣减少约90%,低度宫颈细胞学异常减少约45%,经组织学证实的高度宫颈异常减少约85%。但HPV疫苗接种计划的公共卫生潜力尚未完全实现,HPV相关疾病仍具有较高的发病率和死亡率,因此仍需要提高HPV疫苗接种计划的人群覆盖率。Suzanne M.Garland Susanne K.Kjaer Nubia Muoz Stan L.Block Darron R.Brown Mark J.DiNubile Brianna R.Lindsay Barbara J.Kuter Gonzalo Perez Geraldine Dominiak-Felden Alfred J.Saah Rosybel Drury Rituparna Das Christine Velicer 王华庆 2018中国病毒病杂志2018,8,4:9
16牙列缺失患者种植体支持的固定和可摘义齿的回顾性研究显示文摘目的:研究十年观察期内种植体支持的固定和可摘义齿修复牙列缺失患者种植体的生存率和影响因素。方法:1995-2006年,227例患者(92例男性,135例女性)平均年龄63.7岁,在Charite’大学口腔颌面外科门诊接受种植和修复治疗。共1652颗种植体种植在牙列缺失上颌骨、下颌骨或双侧颌骨,支持76例(24.68%)固定义齿,232例(75.32%)可摘义齿。观察性别,种植体部位、修复方法对种植体生存率的影响。结果:其中有50例患者73颗种植体丧失,累计种植体生存率94.76%,本研究显示种植体生存率女性(93.93%)略低于男性(95.93%),但没有显著性差异。在上颌骨种植的种植体生存率(95.87%)略高于在下颌骨种植(94.53%),但统计学没有显著性意义。10年累计固定和可摘义齿的种植体生存率分别是98.02%和93.55%,两种修复方法差异有显著性。结论:确认了种植体支持牙列缺失患者修复中长期的成功率,并得出结论种植体生存率与性别,种植部位关系不大,与修复方法有关。种植体支持的固定义齿预后比可摘义齿好。项立新 熊亚茸 Katja Nelson Susanne Heberer Semper Wiebke 2010口腔颌面修复学杂志2010,11,1:8
17利用卫星数据估算波罗的海的透明度和透光层深度显示文摘波罗的海水体透明度的长期变化趋势已按富营养化的观点加以解释。可以通过遥感数据估算得到光谱衰减系数K_d(490)。由于漫衰减系数与透明度之间存在着经验和理论关系,因此,利用遥感数据估算海水营养状态是可能的。本文研究了遥感和水下实测K_d(490)与分别于1999年在东波罗的海本体海区和2001年、2002年在西波罗的海本体海区/希默海区(Himmerfjrden)专门海上观测中获得的透明度之间的关系。利用水下测量值通过回归分析方法建立波罗的海PAR与光谱衰减系数间的关系。分析表明,在调查海区,K_d(490)约为K_d(PAR)的1.48倍。该关系用于定义透光层深度与遥感光学深度K_d(490)^(-1)间的关系。结果表明,透光层深度约是K_d(490)^(-1)的6.8倍。K_d(PAR)与透明度的回归分析结果证实了已有的研究结果,即K_d(PAR)为透明度倒数的1.7倍。再者,透明度与K_d(490)之间的水体成分反演算法用于模拟制作由SeaWiFS K_d(490)获得的波罗的海透明度分布图。该分布图通过海上实测数据加以验证,对卫星遥感获得的K_d(490)与实测K_d(490)做了对比,并讨论了产生误差的原因。Susanne Kratzer Bertil Hkansson Charlotte Sahlin 李四海 2003AMBIO-人类环境杂志2003,32,8:8
18Improvement of quantitative testing of liver function in patients with chronic hepatitis C after installment of antiviral therapy显示文摘AIM: To investigate if and to what extent antiviral therapy influenced a broad panel of quantitative testing of liver function (QTLF).METHODS: Fifty patients with chronic hepatitis C were either treated with interferon (n = 8), interferon/ribavirin (n = 19) or peg-interferon/ribavirin (n = 23). Quantitative testing of liver function, including aminopyrine breath test (ABT), galactose elimination capacity (GEC), sorbitol clearance (SCI) and indocyanine green clearance (ICG)was performed before and 3 mo after initiation of antiviral therapy.RESULTS: After 3 mo of antiviral treatment, 36 patients showed normal transaminases and were negative for HCV-RNA, 14 patients did not respond to therapy. ABT and GEC as parameters of microsomal and cytosolic liver function were reduced in all patients before therapy initiation and returned to normal values in the 36 therapy responders after 3 mo. Parameters of liver perfusion (SCI and ICG) were not affected by antiviral therapy. In the 14 non-responders,no changes in QTLF values were observed during the treatment period.CONCLUSION: ICG and SCI remained unaffected in patients with chronic hepatitis C, while ABT and GEC were significantly compromised. ABT and GEC normalized in responders to antiviral therapy. Early determination of ABT and GEC may differentiate responders from non-responders to antivJral treatment in hepatitis C.Matthias Ocker Marion Ganslmayer Steffen Zopf Susanne Gahr Christopher Janson Eckhart G.

19通过贻贝养殖改善海水水质:瑞典社会的可盈利性方案显示文摘沿海水域的富营养化是一个在全球范围内需要付出巨大社会代价的严重的环境问题。在斯卡格拉克海峡东部,富营养化的降低计划通过氮输入量的减少逐步实现,但目前还不清楚如何去减少氮的输入量。其中一个可能的方法是养殖紫贻贝等滤食性生物,这种贻贝能够在生产海产品、饲料和农业肥料的同时也能够除去氮,从而将营养盐由海洋再循环到了陆地上。在瑞典西海岸的古尔马峡湾,我们对贻贝养殖可能对氮循环产生的影响进行了模拟。结果显示,该峡湾口地区氮的净输送量(溶解氮和颗粒状氮的总和)下降了20%。现有的商业贻贝养殖场已经免费提供了这种服务,但它对社会带来的利益将会远远大于这些。我们建议,不应该向贻贝饲养人支付劳动报酬,而应引入营养交换体制以提高沿海水域的状况。在这样的背景下提出了一个通过养殖贻贝来替代在吕瑟希尔社区的污水处理厂中消减氮含量的选择方案。生体毒素的聚积已被确定为瑞典的商业贻贝养殖进一步扩大方面的最大障碍,但这一问题似乎可以通过新技术和管理战略得以解决。在现有和可能的规定和支付费用的基础上,我们提出了一些可能会实现双赢的解决方案。Odd Lindahl Rob Hart Bodil Hernroth Sven Kollberg Lars-Ove Loo Lars Olrog Ann-Sofi Rehnstam-Holm Jonny Svensson Susanne Svensson Ulf Syversen 许天虎 2005AMBIO-人类环境杂志2005,34,2:7
20Collagen/hyaluronan based hydrogels releasing sulfated hyaluronan improve dermal wound healing in diabetic mice via reducing inflammatory macrophage activity显示文摘Sustained inflammation associated with dysregulated macrophage activation prevents tissue formation and healing of chronic wounds.Control of inflammation and immune cell functions thus represents a promising approach in the development of advanced therapeutic strategies.Here we describe immunomodulatory hyaluronan/collagen(HA-AC/coll)-based hydrogels containing high-sulfated hyaluronan(sHA)as immunoregulatory component for the modulation of inflammatory macrophage activities in disturbed wound healing.Solute sHA downregulates inflammatory activities of bone marrow-derived and tissue-resident macrophages in vitro.This further affects macrophage-mediated pro-inflammatory activation of skin cells as shown in skin ex-vivo cultures.In a mouse model of acute skin inflammation,intradermal injection of sHA downregulates the inflammatory processes in the skin.This is associated with the promotion of an anti-inflammatory gene signature in skin macrophages indicating a shift of their activation profile.For in vivo translation,we designed HA-AC/coll hydrogels allowing delivery of sHA into wounds over a period of at least one week.Their immunoregulatory capacity was analyzed in a translational experimental approach in skin wounds of diabetic db/db mice,an established model for disturbed wound healing.The sHA-releasing hydrogels improved defective tissue repair with reduced inflammation,augmented pro-regenerative macrophage activation,increased vascularization,and accelerated new tissue formation and wound closure.Sophia Hauck Paula Zager Norbert Halfter Elke Wandel Marta Torregrossa Ainur Kakpenova Sandra Rother Michelle Ordieres Susann Räthel Albrecht Berg Stephanie Möller Matthias Schnabelrauch Jan C.Simon Vera Hintze Sandra Franz 2021Bioactive Materials2021,6,12:7
