| 1 | Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand?显示文摘Diffusion-weighted imaging (DWI) is one of the magnetic resonance imaging (MRI) sequences providing qualitative as well as quantitative information at a cellular level. It has been widely used for various applications in the central nervous system. Over the past decade, various extracranial applications of DWI have been increasingly explored, as it may detect changes even before signal alterations or morphological abnormalities become apparent on other pulse sequences. Initial results from abdominal MRI applications are promising, particularly in oncological settings and for the detection of abscesses. The purpose of this article is to describe the clinically relevant basic concepts of DWI, techniques to perform abdominal DWI, its analysis and applications in abdominal visceral MR imaging, in addition to a brief overview of whole body DWI MRI. | Ajaykumar C Morani Khaled M Elsayes Peter S Liu William J Weadock Janio Szklaruk Jonathan Russell Dillman Asra Khan Thomas L Chenevert Hero K Hussain | 2013 | World Journal of Radiology2013，5，3： | 12 |
| 2 | 羧甲基木薯淀粉的取代方式研究显示文摘采用高效液相色谱(HPLC)和核磁共振波谱(1HNMR)分析了混水/有机介质中合成羧甲基木薯淀 粉的取代方式。发现HPLC是一种测定不同条件下合成的羧甲基木薯淀粉取代度(DS)的可靠方法。在测量 的范围内,未取代、一取代、二取代和三取代无水葡萄糖单元的摩尔分数分布和Spurlin模型非常吻合。用高 分辨率500MHz1HNMR分析了木薯淀粉羧甲基过程的取代度和反应顺序。依据淀粉和羧甲基淀粉(CMS) 的结构确定了各个峰位置。比较所得数据发现:依据HPLC计算的DSHPLC小于从500MHz1HNMR计算所得 的DS。无水葡萄糖单元中C2、C3和C6的羧甲基化反应顺序为C6>C2>C3。 | 姚杰 尤宏 包正 沈晋 Klaassien J Ganzeveld Jan Henk Marsman Hero J Heeres 陈文仁 | 2005 | 分析化学2005，33，2： | 8 |
| 3 | HBeAg negative serological status and low viral replication levels characterize chronic hepatitis B virus-infected women at reproductive age in Greece: A one-year prospective single center study显示文摘AIM: To evaluate the seroprevalence of hepatitis B surface antigen (HBsAg) in 13 581 women at reproductive age and the hepatitis B e antigen (HBeAg)/anti-HBe status as well as serum hepatitis B virus (HBV)-DNA levels in a subgroup of HBsAg(+) pregnant women at labor in Greece.METHODS: Serological markers were detected using enzyme immunoassays. Serum HBV-DNA was determined by a sensitive quantitative PCR assay. Statistical analysis of data was based on parametric methodology.RESULTS: Overall, 1.156% of women were HBsAg(+)and the majority of them (71.3%) were Albanian. The prevalence of HBsAg was 5.1% in Albanian women, 4.2%in Asian women and 1.14% in women from Eastem European countries. The prevalence of HBsAg in African (0.36%) and Greek women (0.29%) was very low. Only 4.45% of HBsAg (+) women were also HBeAg(+) whereas the vast majority of them were HBeAg(-)/anti-HBe(+). Undetectable levels of viremia (<200 copies/mL) were observed in 32.26% of pregnant women at labor and 29.03% exhibited extremely low levels of viral replication (<400 copies/mL). Only two pregnant women exhibited extremely high serum HBVDNA levels (>10 000 000 copies/mL), whereas 32.26%exhibited HBV-DNA levels between 1 500 and 40 000copies/mL.CONCLUSION: The overall prevalence of HBsAg is relatively low among women at reproductive age in Greece but is higher enough among specific populations. The HBeAg(-)/anti-HBe(+) serological status and the extremely low or even undetectable viral replicative status in the majority of HBsAg(+) women of our study population, suggest that only a small proportion of HBsAg(+) women in Greece exhibit a high risk for vertical transmission of the infection. | Ioannis S.

| 6 | Translation and validation of the Greek chronic liver disease questionnaire显示文摘AIM:To translate into Greek and validate the chronic liver disease questionnaire (CLDQ).METHODS:Two hundred and six consecutive adult patients with the diagnosis of a chronic liver disease from 2 general hospitals in Athens were enrolled in the study from May to September 2008.In order to assess their quality of life (QOL) the CLDQ was applied.The instrument was translated from English,back translated and reviewed in focus groups within the framework of a large multicenter study.The measurements that were performed included:2 independent sample t tests,oneway analysis of variance,reliability coefficients,explanatory factor analysis using a varimax rotation and the principal components method.RESULTS:One hundred and twenty five (61%) patients were men,half were aged 40-59 years and > 33% were > 60 years old.Among the patients,48 (23%) were hospitalized and 97 (47%) were cirrhotic according to the Child-Pugh score.The internal consistency of the Greek CLDQ version using Cronbach's alpha coefficient was found to be 0.93.Exploratory factor analysis identified 7 domains accounting for 65% of the variance of CLDQ items and only partially overlapping with those found in the original version.The area under the receiver operating characteristics curve was calculated at 0.813 and the logistic estimate for the threshold score of 167.50 provided a sensitivity of 74.3% and a specificity of 71.6% for the model.CONCLUSION:Our data confirmed the validity of the Greek version of the CLDQ in identifying the QOL among patients with chronic liver disease. | Zoi Kollia Evridiki Patelarou Victoria Vivilaki Eleni Kollia Florentia Kefou Ioannis Elefsiniotis Spyros P Dourakis Hero Brokalaki | 2010 | World Journal of Gastroenterology2010，16，46： | 2 |
