1WJD 5^(th) Anniversary Special Issues(2): Type 2 diabetes Inflammation in diabetic kidney disease显示文摘Diabetes mellitus entails significant health problems worldwide.The pathogenesis of diabetes is multifactorial,resulting from interactions of both genetic and environmental factors that trigger a complex network of pathophysiological events,with metabolic and hemodynamic alterations.In this context,inflammation has emerged as a key pathophysiology mechanism.New pathogenic pathways will provide targets for prevention or future treatments.This review will focus on the implications of inflammation in diabetes mellitus,with special attention to inflammatory cytokines.Patricia M García-García María A Getino-Melian Virginia Domínguez-Pimentel Juan F Navarro-Gonzalez 2014World Journal of Diabetes2014,5,4:26

3Subclinical carotid atherosclerosis predicts all-cause mortality and cardiovascular events in obese patients with negative exercise echocardiography显示文摘BACKGROUND Obesity is a major health problem due to its high prevalence. The relationship between obesity and cardiovascular disease is unclear. Some studies agree that certain conditions associated with obesity, such as physical inactivity or cardiovascular risk factors, are responsible for cardiovascular risk excess among obese people. Carotid intima-media thickness and carotid plaques(CP) have been associated with cardiovascular adverse events in healthy populations, and recent data suggest a higher prevalence of subclinical carotid atherosclerosis in obese and metabolically unhealthy patients. However, there are no studies correlating subclinical atherosclerosis and adverse events(AE) in obese subjects.AIM To determine the association between carotid disease and AE in obese patients with negative exercise echocardiography(EE).METHODS From January 1, 2006 to December 31, 2010, 2000 consecutive patients with a suspicion of coronary artery disease were submitted for EE and carotid ultrasonography. Exclusion criteria included previous vascular disease, left ventricular ejection fraction < 50%, positive EE, significant valvular heart disease and inferior to submaximal EE. An AE was defined as all-cause mortality,myocardial infarction and cerebrovascular accident. Subclinical atherosclerosis was defined as CP presence according to Manheim and the American Society of Echocardiography Consensus.RESULTS Of the 652 patients who fulfilled the inclusion criteria, 226(34.7%) had body mass indexes ≥ 30 kg/m2, and 76 of them(33.6%) had CP. During a mean follow-up time of 8.2(2.1) years, 27 AE were found(11.9%). Mean event-free survival at 1, 5 and 10 years was 99.1%(0.6), 95.1%(1.4) and 86.5%(2.7), respectively. In univariate analysis, CP predicted AE [hazard ratio(HR) 2.52, 95% confidence interval(CI) 1.17-5.46; P = 0.019]. In multivariable analysis, the presence of CP remained a predictor of AE(HR 2.26, 95%CI 1.04-4.95, P = 0.041). Other predictors identified were glomerular filtration rate(HR 0.98, 95%CI 0.96-0.99; P= 0.023), peak metabolic equivalents(HR 0.83, 95%CI 0.70–0.99, P = 0.034) and moderate mitral regurgitation(HR 5.02, 95%CI 1.42–17.75, P = 0.012).CONCLUSION Subclinical atherosclerosis defined by CP predicts AE in obese patients with negative EE. These patients could benefit from aggressive prevention measures.Rafael Vidal-Perez Raúl Franco-Gutiérrez Alberto J Pérez-Pérez Virginia Franco-Gutiérrez Alberto Gascón-Vázquez Andrea López-López Ana María Testa-Fernández Carlos González-Juanatey 2019World Journal of Cardiology2019,11,1:7
4T_3-induced liver AMP-activated protein kinase signaling:Redox dependency and upregulation of downstream targets显示文摘AIM:To investigate the redox dependency and promotion of downstream targets in thyroid hormone(T3)-induced AMP-activated protein kinase(AMPK)signaling as cellular energy sensor to limit metabolic stresses in the liver.METHODS:Fed male Sprague-Dawley rats were given a single ip dose of 0.1 mg T3/kg or T3 vehicle(Na OH0.1 N;controls)and studied at 8 or 24 h after treatment.Separate groups of animals received 500 mg N-acetylcysteine(NAC)/kg or saline ip 30 min prior T3.Measurements included plasma and liver 8-isoprostane and serumβ-hydroxybutyrate levels(ELISA),hepaticlevels of m RNAs(q PCR),proteins(Western blot),and phosphorylated AMPK(ELISA).RESULTS:T3 upregulates AMPK signaling,including the upstream kinases Ca2+-calmodulin-dependent protein kinase kinase-βand transforming growth factor-β-activated kinase-1,with T3-induced reactive oxygen species having a causal role due to its suppression by pretreatment with the antioxidant NAC.Accordingly,AMPK targets acetyl-Co A carboxylase and cyclic AMP response element binding protein are phosphorylated,with the concomitant carnitine palmitoyltransferase-1α(CPT-1α)activation and higher expression of peroxisome proliferator-activated receptor-γco-activator-1αand that of the fatty acid oxidation(FAO)-related enzymes CPT-1α,acyl-Co A oxidase 1,and acylCo A thioesterase 2.Under these conditions,T3 induced a significant increase in the serum levels ofβ-hydroxybutyrate,a surrogate marker for hepatic FAO.CONCLUSION:T3 administration activates liver AMPK signaling in a redox-dependent manner,leading to FAO enhancement as evidenced by the consequent ketogenic response,which may constitute a key molecular mechanism regulating energy dynamics to support T3preconditioning against ischemia-reperfusion injury.Luis A Videla Virginia Fernández Pamela Cornejo Romina Vargas Paula Morales Juan Ceballo Alvaro Fischer Nicolás Escudero Oscar Escobar 2014World Journal of Gastroenterology2014,20,46:3
5Mechanisms implicated in the contralateral effect in the central nervous system after unilateral injury:focus on the visual system显示文摘The retina,as part of the central nervous system is an ideal model to study the response of neurons to injury and disease and to test new treatments.During the last decade is becoming clear that unilateral lesions in bilateral areas of the central nervous system trigger an inflammatory response in the contralateral uninjured site.This effect has been better studied in the visual system where,as a rule,one retina is used as experimental and the other as control.Contralateral retinas in unilateral models of retinal injury show neuronal degeneration and glial activation.The mechanisms by which this adverse response in the central nervous system occurs are discussed in this review,focusing primarily on the visual system.Fernando Lucas-Ruiz Caridad Galindo-Romero Virginia Albaladejo-García Manuel Vidal-Sanz Marta Agudo-Barriuso 2021Neural Regeneration Research2021,16,11:2
6在肝 preconditioning 的最近的进展: 甲状腺荷尔蒙, n-3 长链的多元不堡和丰满的酸和熨斗显示文摘 Liver preconditioning (PC), defined as an enhanced tolerance to injuring stimuli induced by previous specific maneuvers triggering beneficial functional and molecular changes, is of crucial importance in human liver transplantation and major hepatic resection. For these reasons, numerous PC strategies have been evaluated in experimental models of ischemia-reperfusion liver injury, which have not been transferred to clinical application due to side effects, toxicity and difficulties in implementation, with the exception of the controversial ischemic PC. In recent years, our group has undertaken the assessment of alternate experimental liver PC protocols that might have application in the clinical setting. These include thyroid hormone (T3), n-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA), or iron, which suppressed liver damage due to the 1 h ischemia-20 h reperfusion protocol. T3, n-3 LCPUFA and iron are hormetic agents that trigger biologically beneficial effects in the low-dose range, whose multifactorial mechanisms of action are discussed in the work.Virginia Fernández Gladys Tapia Luis A Videla 2012World Journal of Hepatology2012,4,4:2
