目的确定超声辐射压力脉冲派生的弹性成像的肠壁剪切波速度(SWV)能否区分克罗恩病动物模型的肠纤维化和急性炎症。材料与方法本研究经大学动物应用与保护委员会批准。对8只Lewis鼠行一次三硝基苯磺酸(TNBS)灌肠制作克罗恩病急性炎症模型,2d后对6只存活的大鼠进行影像检查。4周内对另外8只Lewis鼠进行重复TNBS灌肠得到克罗恩病纤维化模型,待7d后急性炎症消散后,对存活的7只大鼠进行影像检查。对所有大鼠均行9次加压或不加压的经皮肠壁SWV测定。应用Studentt检验比较两组动物间加压或不加压时的平均SWV,并生成受试者操作特征曲线(ROC)以评估诊断效力。结果纤维化组大鼠的平均肠壁SWV在加压0[(3.4±1.1)m/s∶(2.3±0.5)m/s;P=0.047]和加压30%时[(6.3±2.2)m/s∶(3.6±0.9)m/s;P=0.02]明显高于急性炎症组大鼠。两组大鼠的平均SWV均随施加压力的增加呈线性增高,并且平均斜率(P=0.02)与y轴截距(P=0.02)在组间存在显著差异。应用SWV比率(平均SWV/施加的压力)在病理组织学上识别肠管炎和纤维化,其ROC曲线下面积为0.971。结论肠壁SWV有助于识别克罗恩病动物模型中的肠纤维化和急性炎症。

AIM: To analyze through meta-analyses the benefits of two types of stents in the inoperable malignant biliary ***: A systematic review of randomized clinical trials(RCT) was conducted, with the last update on March 2015, using EMBASE, CINAHL(EBSCO), MEDLINE, LILACS/CENTRAL(BVS), SCOPUS, CAPES(Brazil), and gray literature. Information of the selected studies was extracted in sight of six outcomes: primarily regarding dysfunction, complication and reintervention rates; and secondarily costs, survival, and patency time. The data about characteristics of trial participants, inclusion and exclusion criteria and types of stents were also extracted. The bias was mainly assessed through the jADAD scale. This meta-analysis was registered in the PROSPERO database by the number CRD42014015078. The analysis of the absolute risk of the outcomes was performed using the software Rev Man, by computing risk differences(RD) of dichotomous variables and mean differences(MD) of continuous variables. Data on RD and MD for each primary outcome were calculated using the MantelHaenszel test and inconsistency was qualified and reported in χ2 and the higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%, a subsequent assay was done and other findings were compiled. Student's t-test was used for the comparison of weighted arithmetic means regarding secondary ***: Initial searching identified 3660 studies; 3539 were excluded through title, repetition, and/or abstract, while 121 studies were fully assessed and were excluded mainly because they did not compare self-expanding metal stents(SEMS) and plastic stents(PS), leading to thirteen RCT selected, with 13 articles and 1133 subjects meta-analyzed. The mean age was 69.5 years old, that were affected mostly by bile duct(proximal) and pancreatic tumors(distal). The preferred SEMS diameter used was the 10 mm(30 Fr) and the preferred PS diameter used was 10 Fr. In the metaanalysis

AIM To determine the best option for bowel preparation [sodium picosulphate or polyethylene glycol(PEG)] for elective colonoscopy in adult *** A systematic review of the literature following the PRISMA guidelines was performed using Medline, Scopus, EMBASE, Central, Cinahl and Lilacs. No restrictions were placed for country, year of publication or language. The last search in the literature was performed on November 20th, 2017. Only randomized clinical trials with full texts published were included. The subjects included were adult outpatients who underwent bowel cleansing for elective colonoscopy. The included studies compared sodium picosulphate with magnesium citrate(SPMC)and PEG for bowel preparation. Exclusion criteria were the inclusion of inpatients or groups with specific conditions, failure to mention patient status(outpatient or inpatient) or dietary restrictions, and permission to have unrestricted diet on the day prior to the exam. Primary outcomes were bowel cleaning success and/or tolerability of colon preparation. Secondary outcomes were adverse events, polyp and adenoma detection rates. Data on intention-totreat were extracted by two independent authors and risk of bias assessed through the jadad scale. Funnel plots, Egger's test, higgins' test(I2) and sensitivity analyses were used to assess reporting bias and heterogeneity. The meta-analysis was performed by computing risk difference(RD) using MantelHaenszel(MH) method with fixed-effects(FE) and random-effects(RE) *** Manager 5(RevMan 5) version 6.1(The Cochrane Collaboration) was the software chosen to perform the ***662 records were identified but only 16 trials with 6200 subjects were included for the meta-analysis. High heterogeneity among studies was found and sensitivity analysis was needed and performed to interpret data. In the pooled analysis,SPMC was better for bowel cleaning [MH FE, RD 0.03, IC(0.01, 0.05), P = 0.003, I2= 33%, NNT 34], for tole

琼脂双扩散血清试验表明，参试的我国花生矮化病毒（ＰＳＶ）６个分离物和株系之间血清学关系十分亲近，而与美国ＰＳＶ－Ｅ和ＰＳＶ－Ｗ株系存在明显的差异。完成对花生致病力不同的ＰＳＶ－Ｍｉ和ＰＳＶ－Ｓ两个株系壳蛋白（ＣＰ）基因的ＲＴ－ＰＣＲ扩增、克隆和序列分析。两个株系ＣＰ基因均含６５４个核苷酸，编码２１８个氨基酸。两株系之间ＣＰ基因核苷酸序列同源性为９９．１％，推导的ＣＰ氨基酸序列同源性为９９．５％。与已报道的ＰＳＶ亚组ＩＰＳＶ－ＥＲ和ＰＳＶ－Ｊ株系ＣＰ基因核苷酸序列同源性为７５．７％～７７．８％，与ＰＳＶ亚组ⅡＰＳＶ－ＷＣＰ基因核苷酸序列同源性为７４．３％－７４．６％。鉴于我国ＦＳＶ株系血清学性质和ＣＰ基因核苷酸序列同源性与ＰＳＶ两个亚组的ＰＳＶ株系存在明显的差异，建议将我国ＰＳＶ株系划为一个新的ＰＳＶ亚组，即ＰＳＶ亚组－Ⅲ。
