| 1 | Fatty liver disease in severe obese patients:Diagnostic value of abdominal ultrasound显示文摘AIM:To evaluate the sensitivity and specificity of abdominal ultrasound (US) for the diagnosis of hepatic steatosis in severe obese subjects and its relation to histological grade of steatosis. METHODS: A consecutive series of obese patients, who underwent bariatric surgery from October 2004 to May 2005, was selected. Ultrasonography was performed in all patients as part of routine preoperative time and an intraoperative wedge biopsy was obtained at the beginning of the bariatric surgery. The US and histological findings of steatosis were compared, considering histology as the gold standard. RESULTS: The study included 105 patients. The mean age was 37.2 ± 10.6 years and 75.2% were female. The histological prevalence of steatosis was 89.5%. The sensitivity and specificity of US in the diagnosis of hepatic steatosis were, respectively, 64.9% (95% CI: 54.9-74.3) and 90.9% (95% CI: 57.1-99.5). The positive predictive value and negative predictive value were, respectively, 98.4% (95% CI: 90.2-99.9) and 23.3% (95% CI: 12.3-39.0). The presence of steatosis onUS was associated to advanced grades of steatosis on histology (P = 0.016). CONCLUSION: Preoperative abdominal US in our series has not shown to be an accurate method for the diagnosis of hepatic steatosis in severe obese patients. Until another non-invasive method demonstrates better sensitivity and specificity values, histological evaluation may be recommended to these patients undergoing bariatric surgery. | Alessandro de Moura Almeida Helma Pinchemel Cotrim Daniel Batista Valente Barbosa Luciana Gordilho Matteoni de Athayde Adimeia Souza Santos Almir Galvo Vieira Bitencourt Luiz Antonio Rodrigues de Freitas Adriano Rios Erivaldo Alves | 2008 | World Journal of Gastroenterology2008，14，9： | 10 |
| 2 | Nonalcoholic fatty liver disease in asymptomatic Brazilian adolescents显示文摘AIM:To evaluate the prevalence and clinical characteristics of Nonalcoholic fatty liver disease(NAFLD) among asymptomatic Brazilian adolescents. METHODS:Transversal observational study included asymptomatic adolescents with central obesity from private and public schools in Salvador-Bahia,northeastern Brazil.The children answered a questionnaire that included age,gender,race,and medical history,and were submitted to a complete physical exam and abdominal ultrasound.Biochemical exams included:ALT,AST,GGT,C reactive protein(CRP),fasting glucose,insulin,cholesterol and triglycerides.Criteria for NAFLD included:the presence of steatosis in ultrasound and/or high level of ALT,negative or occasional historic of intake of alcohol(≤140 g/wk),negative investigation for hepatitis A,B,C,auto-immune hepatitis,Wilson disease and hemochromatosis.RESULTS:From October,2005 to October,2006,the study included 1801 subjects between 11 and 18 years of age and a mean age of 13.7±2.0 years.One hundred ninety-nine had central obesity.The prevalence of NAFLD was 2.3%,most of whom were male and white.Insulin resistance(IR)was observed in 22.9% of them and had positive correlations with ALT and GGT(P<0.05).Elevated CRP was observed in 6.9% of the cases;however,it was not associated with WC,IR or liver enzymes. CONCLUSION:The prevalence of NAFLD in Brazilian adolescents was low.The ethnicity may have influence this frequency in the population studied,which had a large proportion of African descendents. | Raquel Rocha Helma Pinchemel Cotrim Almir Galvo Vieira Bitencourt Daniel Batista Valente Barbosa Adméia Souza Santos Alessandro de Moura Almeida Bruno Cunha Isabel Guimares | 2009 | World Journal of Gastroenterology2009，15，4： | 2 |

| 18 | Geological,Structural and Mineralogical Approach to Investigate the Evolution of Low-and very Low-Grade Metamorphic Units from the Intra-Pontide Suture Zone,Central Pontides,Turkey显示文摘A multidisciplinary approach combining multiscale geological-structural analyses(from field to microscale) and clay mineral transformations(clay mineralogy, illite and chlorite 'crystallinity' and b cell dimension(b_(0)) of K-white mica) was adopted to unravel the tectono-metamorphic evolution of low-and very low-grade tectono-metamorphic units from the Intra-Pontide suture zone in northern Turkey. The mineralogical study allowed to better evaluate the structural stacking outlined during the geological mapping, leading to distinguish three tectono-metamorphic units, two in epizone(Daday and Emirkoy units) and one in anchizone(Cifter Unit) metamorphic conditions. The mesostructural and microstructural analyses suggest a polyphase tectonic-metamorphic evolution. The different macroscopic features observed between the two units characterized by the same epizone metamorphism, can be justified by the evidence that these metamorphic conditions were acquired during the last stages of exhumation in the Daday Unit, while they constrained the metamorphic-peak conditions in the Emirkoy Unit. Contemporary analyses and comparison between structural and mineralogical data have thus proven to be a powerful tool to investigate the low-grade and very low-grade metamorphic environments, allowing at the same time to solve the apparent contradictions deriving from the mineralogical study and to significantly improve the detail of the geological mapping in the field. | Alessandro Ellero Chiara Frassi Mehmet Cemal Göncüoğlu Marco Lezzerini Michele Marroni Giuseppe Ottria Luca Pandolfi Kaan Sayit Marco Tamponi | 2021 | Journal of Earth Science2021，32，6： | 1 |

| 20 | 血浆和(或)酵母提取物对7-63日龄仔猪生长性能和肠道形态的影响显示文摘研究旨在评估在7~63日龄仔猪日粮中添加血浆和(或)酵母提取物对仔猪日增质量、日采食量和饲料转化率及肠道形态的影响。试验采用288头体质量为(2.57±0.05)kg的7日龄仔猪,按照日粮差别随机分为4组,每组6个重复,每重复12头仔猪。试验预备期I(7~21日龄)、预备期II(22—35日龄)及第1阶段(36~49日龄)各组日粮为对照组(CD组),不添加血浆或酵母提取物;血浆组(PL组),添加6%、4%和2%血浆;酵母提取物组(YE组),添加6%、4%和2%酵母提取物;血浆+酵母提取物组(PL+YE组),血浆和酵母提取物分别添加3%、2%和1%。第1I阶段(50—63日龄)所有仔猪饲喂相同的饲料。7~21和7~28日龄没有观察到生长性能的差别,但是第7天一第35天PL+YE组的日增质量有优势(CD、PL、YE和PL+YE组的日增质量分别为268、278、271和288g)。观察7~49及7~63日龄发现,PL+YE组仔猪的日增质量(分别为330和519g)和日采食量(分别为307和647g)都比CD组的日增质量(分别为295和486g)和日采食量(分别为266和594g)要高。不同组间的肠道形态没有显著差异(P〉0.05)。试验结果表明,血浆和酵母提取物提高7~63日龄的仔猪日增质量,但是没有影响到仔猪的肠道形态。 | Leandro César Milagres Rigueira Maria Cristina Thomaz Dalton César Milagres Rigueira Leonardo Augusto Fonseca Pascoal Alessandro Borges Amorim Fábio Enrique Lemos Budio 周小辉 骆明霞 严书林 | 2014 | 饲料研究2014，37，9： | 1 |
