1Recent advances in the diagnosis and treatment of acute myocardial infarction显示文摘The Third Universal Definition of Myocardial Infarction(MI) requires cardiac myocyte necrosis with an increase and/or a decrease in a patient's plasma of cardiac troponin(cT n) with at least one cT n measurement greater than the 99 th percentile of the upper normal reference limit during:(1) symptoms of myocardialischemia;(2) new significant electrocardiogram(ECG) ST-segment/T-wave changes or left bundle branch block;(3) the development of pathological ECG Q waves;(4) new loss of viable myocardium or regional wall motion abnormality identified by an imaging procedure; or(5) identification of intracoronary thrombus by angiography or autopsy.Myocardial infarction,when diagnosed,is now classified into five types.Detection of a rise and a fall of troponin are essential to the diagnosis of acute MI.However,high sensitivity troponin assays can increase the sensitivity but decrease the specificity of MI diagnosis.The ECG remains a cornerstone in the diagnosis of MI and should be frequently repeated,especially if the initial ECG is not diagnostic of MI.There have been significant advances in adjunctive pharmacotherapy,procedural techniques and stent technology in the treatment of patients with MIs.The routine use of antiplatelet agents such as clopidogrel,prasugrel or ticagrelor,in addition to aspirin,reduces patient morbidity and mortality.Percutaneous coronary intervention(PCI) in a timely manner is the primary treatment of patients with acute ST segment elevation MI.Drug eluting coronary stents are safe and beneficial with primary coronary intervention.Treatment with direct thrombin inhibitors during PCI is non-inferior to unfractionated heparin and glycoprotein Ⅱb/Ⅲa receptor antagonists and is associated with a significant reduction in bleeding.The intra-coronary use of a glycoprotein Ⅱb/Ⅲa antagonist can reduce infarct size.Pre- and post-conditioning techniques can provide additional cardioprotection.However,the incidence and mortality due to MI continues to be high despite all these recent advances.The initial ten year experience with autologous human bone marrow mononuclear cells(BMCs) in patients with MI showed modest but significant increases in left ventricular(LV) ejection fraction,decreases in LV endsystolic volume and reductions in MI size.These studies established that the intramyocardial or intracoronary administration of stem cells is safe.However,many of these studies consisted of small numbers of patients who were not randomized to BMCs or placebo.The recent LateT ime,Time,and Swiss Multicenter Trials in patientswith MI did not demonstrate significant improvement in patient LV ejection fraction with BMCs in comparison with placebo.Possible explanations include the early use of PCI in these patients,heterogeneous BMC populations which died prematurely from patients with chronic ischemic disease,red blood cell contamination which decreases BMC renewal,and heparin which decreases BMC migration.In contrast,cardiac stem cells from the right atrial appendage and ventricular septum and apex in the SCIPIO and CADUCEUS Trials appear to reduce patient MI size and increase viable myocardium.Additional clinical studies with cardiac stem cells are in progress.Koushik Reddy Asma Khaliq Robert J Henning 2015World Journal of Cardiology2015,7,5:107
2Diagnosis and treatment of heart failure with preserved left ventricular ejection fraction显示文摘Nearly six million people in United States have heart failure.Fifty percent of these people have normal left ventricular(LV)systolic heart function but abnormal diastolic function due to increased LV myocardial stiffness.Most commonly,these patients are elderly women with hypertension,ischemic heart disease,atrial fibrillation,obesity,diabetes mellitus,renal disease,or obstructive lung disease.The annual mortality rate of these patients is 8%-12%per year.The diagnosis is based on the history,physical examination,laboratory data,echocardiography,and,when necessary,by cardiac catheterization.Patients with obesity,hypertension,atrial fibrillation,and volume overload require weight reduction,an exercise program,aggressive control of blood pressure and heart rate,and diuretics.Miniature devices inserted into patients for pulmonary artery pressure monitoring provide early warning of increased pulmonary pressure and congestion.If significant coronary heart disease is present,coronary revascularization should be considered.Robert J Henning 2020World Journal of Cardiology2020,12,1:9
3Molecular mechanism and functional consequences of lansoprazole-mediated heme oxygenase-1 induction显示文摘AIM:To investigate the molecular mechanism and functional consequences of heme oxygenase-1(HO-1) activation by lansoprazole in endothelial cells and macrophages. METHODS:Expression of HO-1 mRNA was analyzed by Northern blotting.Western blotting was used to determine the HO-1 and ferritin protein levels. NADPH-dependent reactive oxygen species(ROS) formation was measured with lucigenin-enhanced chemiluminescence.HO-1 promoter activity in mouse fibroblasts,stably transfected with a 15-kb HO-1 gene that drives expression of the reporter gene luciferase, was assessed using in vivo bioluminescence imaging. RESULTS:Lansoprazole increased HO-1 mRNA levels in endothelial cells and HO-1 protein levelsin macrophages.In addition,lansoprazole-induced ferritin protein levels in both cell systems.Moreover, induction of the antioxidant proteins HO-1 and ferritin by lansoprazole was followed by a decrease in NADPH- mediated ROS formation.The radical scavenging properties of lansoprazole were diminished in the presence of the HO inhibitor,chromium mesoporphyrin IX.Induction of HO-1 gene expression by lansoprazole was not related to oxidative stress or to the activation of the mitogen-activated protein kinase pathway. However,the phosphatidylinositol 3-kinase inhibitor LY294002 showed a concentration-dependent inhibition of HO-1 mRNA and promoter activity. CONCLUSION:Activation of HO-1 and ferritin may account for the gastric protection of lansoprazole and is dependent on a pathway blocked by LY294002.Stephanie Schulz-Geske Kati Erdmann Ronald J Wong David K Stevenson Henning Schrder Nina Grosser 2009World Journal of Gastroenterology2009,15,35:7
4Targeting cell death signaling in colorectal cancer:Current strategies and future perspectives显示文摘The evasion from controlled cell death induction has been considered as one of the hallmarks of cancer cells.Defects in cell death signaling are a fundamental phenomenon in colorectal cancer.Nearly any non-invasive cancer treatment finally aims to induce cell death.However,apoptosis resistance is the major cause for insufficient therapeutic success and disease relapse in gastrointestinal oncology.Various compounds have been developed and evaluated with the aim to meet with this obstacle by triggering cell death in cancer cells.The aim of this review is to illustrate current approaches and future directions in targeting cell death signaling in colorectal cancer.The complex signaling network of apoptosis will be demonstrated and the'druggability'of targets will be identified.In detail,proteins regulating mitochondrial cell death in colorectal cancer,such as Bcl-2 and survivin,will be discussed with respect to potential therapeutic exploitation.Death receptor signaling and targeting in colorectal cancer will be outlined.Encouraging clinical trials including cell death based targeted therapies for colorectal cancer are under way and will be demonstrated.Our conceptual understanding of cell death in cancer is rapidly emerging and new types of controlled cellular death have been identified.To meet this progress in cell death research,the implication of autophagy and necroptosis for colorectal carcinogenesis and therapeutic approaches will also be depicted.The main focus of this topic highlight will be on the revelation of the complex cell death concepts in colorectal cancer and the bridging from basic research to clinical use.Bruno Christian Koehler Dirk Jger Henning Schulze-Bergkamen 2014World Journal of Gastroenterology2014,20,8:4
5Hepatic encephalopathy before and neurological complications after liver transplantation have no impact on the employment status 1 year after transplantation显示文摘AIM To investigate the impact of hepatic encephalopathybefore orthotopic liver transplantation(OLT) and neurological complications after OLT on employment after OLT.METHODS One hundred and fourteen patients with chronic liver disease aged 18-60 years underwent neurological examination to identify neurological complications, neuropsychological tests comprising the PSE-SyndromeTest yielding the psychometric hepatic encephalopathy score, the critical flicker frequency and the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS), completed a questionnaire concerning their occupation and filled in the short form 36(SF-36) to assess health-related quality of life before OLT and 12 mo after OLT, if possible. Sixty-eight(59.6%) patients were recruited before OLT, while on the waiting list for OLT at Hannover Medical School [age: 48.7 ± 10.2 years, 45(66.2%) male], and 46(40.4%) patients were included directly after OLT. RESULTS Before OLT 43.0% of the patients were employed. The patients not employed before OLT were more often non-academics(employed: Academic/non-academic 16(34.0%)/31 vs not employed 10(17.6%)/52, P = 0.04), had more frequently a history of hepatic encephalopathy(HE)(yes/no; employed 15(30.6%)/34 vs not employed 32(49.2%)/33, P = 0.05) and achieved worse results in psychometric tests(RBANS sum score mean ± SD employed 472.1 ± 44.5 vs not employed 443.1 ± 56.7, P = 0.04) than those employed. Ten patients(18.2%), who were not employed before OLT, resumed work afterwards. The patients employed after OLT were younger [age median(range, min-max) employed 47(42, 18-60) vs not employed 50(31, 29-60), P = 0.01], achieved better results in the psychometric tests(RBANS sum score mean ± SD employed 490.7 ± 48.2 vs not employed 461.0 ± 54.5, P = 0.02) and had a higher health-related quality of life(SF 36 sum score mean ± SD employed 627.0 ± 138.1 vs not employed 433.7 ± 160.8; P < 0.001) compared to patients not employed after OLT. Employment before OLT(P < 0.001), age(P < 0.01) and SF-36 sum score 12 mo after OLT(P < 0.01) but not HE before OLT or neurological complications after OLT were independent predictors of the employment status after OLT.CONCLUSION HE before and neurological complications after OLT have no impact on the employment status 12 mo after OLT. Instead younger age and employment before OLT predict employment one year after OLT.Henning Pflugrad Anita B Tryc Annemarie Goldbecker Christian P Strassburg Hannelore Barg-Hock Jürgen Klempnauer Karin Weissenborn 2017World Journal of Hepatology2017,9,10:3
