1Genomic and genetic alterations influence the progression of gastric cancer显示文摘Gastric cancer is one of the leading causes of cancerrelated deaths worldwide, although the incidence has gradually decreased in many Western countries. Two main gastric cancer histotypes, intestinal and diffuse, are recognised. Although most of the described genetic alterations have been observed in both types, different genetic pathways have been hypothesized. Genetic and epigenetic events, including 1q loss of heterozygosity (LOH), microsatellite instability and hypermethylation, have mostly been reported in intestinal-type gastric carcinoma and its precursor lesions, whereas 17p LOH, mutation or loss of E-cadherin are more often implicated in the development of diffuse-type gastric cancer.In this review, we summarize the sometimes contradictory findings regarding those markers which influence the progression of gastric adenocarcinoma.Stefania Nobili Lorenzo Bruno Ida Landini Cristina Napoli Paolo Bechi Francesco Tonelli Carlos A Rubio Enrico Mini Gabriella Nesi 2011World Journal of Gastroenterology2011,17,3:17
2Predictors of mortality after transjugular portosystemic shunt显示文摘AIM:To investigate if echocardiographic and hemodynamic determinations obtained at the time of transjugular intrahepatic portosystemic shunt(TIPS)can provide prognostic information that will enhance risk stratification of patients.METHODS:We reviewed medical records of 467 patients who underwent TIPS between July 2003 and December 2011 at our institution.We recorded information regarding patient demographics,underlying liver disease,indication for TIPS,baseline laboratory values,hemodynamic determinations at the time of TIPS,and echocardiographic measurements both before and after TIPS.We recorded patient comorbidities that may affect hemodynamic and echocardiographic determinations.We also calculated Model for Endstage Liver Disease(MELD)score and Child Turcotte Pugh(CTP)class.The following pre-and post-TIPS echocardiographic determinations were recorded:Left ventricular ejection fraction,right ventricular(RV)systolic pressure,subjective RV dilation,and subjective RV function.We recorded the following hemodynamic measurements:Right atrial(RA)pressure before and after TIPS,inferior vena cava pressure before and after TIPS,free hepatic vein pressure,portal vein pressure before and after TIPS,and hepatic venous pressure gradient(HVPG).RESULTS:We reviewed 418 patients with portal hypertension undergoing TIPS.RA pressure increased by a mean ± SD of 4.8 ± 3.9 mmH g(P < 0.001),HVPG decreased by 6.8 ± 3.5 mmH g(P < 0.001).In multivariate linear regression analysis,a higher MELD score,lower platelet count,splenectomy and a higher portal vein pressure were independent predictors of higher RA pressure(R = 0.55).Three variables predicted 3-mo mortality after TIPS in a multivariate analysis:Age,MELD score,and CTP grade C.Change in the RA pressure after TIPS predicted long-term mortality(per 1 mm Hg change,HR = 1.03,95%CI:1.01-1.06,P < 0.012).CONCLUSION:RA pressure increased immediately after TIPS particularly in patients with worse liver function,portal hypertension,emergent TIPS placement and history of splenectomy.The increase in RA pressure after TIPS was associated with increased mortality.Age,splenectomy,MELD score and CTP grade were independent predictors of long-term mortality after TIPS.Mona Ascha Sami Abuqayyas Ibrahim Hanouneh Laith Alkukhun Mark Sands Raed A Dweik Adriano R Tonelli 2016World Journal of Hepatology2016,8,11:13
3钢包和中间包内衬耐火材料与碳钢的化学反应显示文摘在有些情况下,对钢产品内部质量的影响并不取决于生产过程中的误操作,而是低估了液态钢水与不同工序中接触到的材料间的化学反应。尤其是在铸锭生产中,这一点尤为明显。讨论了钢包与中间包内衬耐材与普碳钢间发生的化学反应。这些试验涉及高铝质、铝硅质、铝镁尖晶石质耐火材料,研究了它们在液态钢水中形成夹杂物的倾向性。试验结果表明,在钢水—耐材接触面上会产生一个富含MnO的新相,这一新相的量与二氧化硅在耐材中的活性及锰在钢液里的活性成正比。试验还表明,由液态钢水与耐火材料相互反应产生的接触面可产生新的外来夹杂物进入钢液中。试验结束后,对钢样中新的夹杂物成分做的分析表明,成分取决于耐材—钢水接触面的组成。因此,不同钢厂应该结合自身生产的钢种产品化学组成来选用耐火材料的化学成分设计。F Cirilli A Mazzarano M Tonelli 沈钟铭(译) 职建军(校) 2012世界钢铁2012,12,4:3
