1Pathophysiological 角色和在糖尿病的 nephropathy 的发炎的治疗学的含意显示文摘 Diabetes mellitus and its complications are becoming one of the most important health problems in the world. Diabetic nephropathy is now the main cause of end-stage renal disease. The mechanisms leading tothe development and progression of renal injury are not well known. Therefore, it is very important to f ind new pathogenic pathways to provide opportunities for early diagnosis and targets for novel treatments. At the present time, we know that activation of innate immunity with development of a chronic low grade inflammatory response is a recognized factor in the pathogenesis of diabetic nephropathy. Numerous experimental and clinical studies have shown the participation of different inflammatory molecules and pathways in the pathophysiology of this complication.Desirée Luis-Rodríguez Alberto Martínez-Castelao José Luis Górriz Fernando de lvaro Juan F Navarro-González 2012World Journal of Diabetes2012,3,1:55
2MicroRNAs dysregulation in hepatocellular carcinoma: Insights in genomic medicine显示文摘Hepatocellular carcinoma(HCC) is the leading primary liver cancer and its clinical outcome is still poor. MicroRNAs(mi RNAs) have demonstrated an interesting potential to regulate gene expression at post-transcriptional level. Current findings suggest that mi RNAs deregulation in cancer is caused by genetic and/or epigenetic, transcriptional and post-transcriptional modifications resulting in abnormal expression and hallmarks of malignant transformation: aberrant cell growth, cell death, differentiation, angiogenesis, invasion and metástasis. The important role of mi RNAs in the development and progression of HCC has increased the efforts to understand and develop mechanisms of control overt this single-stranded RNAs. Several studies have analyzed tumoral response to the regulation and control of deregulated mi RNAs with good results in vitro and in vivo, proving that targeting aberrant expression of mi RNAs is a powerful anticancer therapeutic. Identification of up and/or down regulated mi RNAs related to HCC has led to the discovery of new potential application for detection of their presence in the affected organism. Mi RNAs represent a relevant new target for diagnosis, prognosis and treatment in a wide variety of pathologic entities, including HCC. This manuscript intends to summarize current knowledge regarding mi RNAs and their role in HCC development.Iván Lyra-González Laura E Flores-Fong Ignacio González-García David Medina-Preciado Juan Armendáriz-Borunda 2015World Journal of Hepatology2015,7,11:9
3Soluble ST2:A new and promising activity marker in ulcerative colitis显示文摘AIM:To correlate circulating soluble ST2(sST2) levels with the severity of ulcerative colitis(UC) and serum levels of pro-inflammatory cytokines,and to demonstrate the predictive power of sST2 levels for differentiation between active and inactive UC.METHODS:We recruited 153 patients:82 with UC,26 with Crohn's disease(CD) and 43 disease controls [non-inflammatory bowel disease(IBD)].Subjects were excluded if they had diagnosis of asthma,autoimmune diseases or hypertension.The serum levels of sST2 and pro-inflammatory cytokines [pg/mL;median(25th-75th)] as well as clinical features,endoscopic and histological features,were subjected to analyses.The sST2 performance for discrimination between active and inactive UC,non-IBD and healthy controls(HC) was determined with regard to sensitivity and specificity,and Spearman's rank correlation coefficient(r).To validate the method,the area under the curve(AUC) of receiver-operator characteristic(ROC) was determined(AUC,95% CI) and the total ST2 content of the colonic mucosa in UC patients was correlated with circulating levels of sST2.RESULTS:The serum sST2 value was significantly higher in patients with active [235.80(90.65-367.90) pg/mL] rather than inactive UC [33.19(20.04-65.32) pg/mL],based on clinical,endoscopic and histopathological characteristics,as well as compared with non-IBD and HC(P < 0.001).The median level of sST2 in CD patients was 54.17(35.02-122.0) pg/mL,significantly higher than that of the HC group only(P < 0.01).The cutoff was set at 74.87 pg/mL to compare active with inactive UC in a multicenter cohort of patients.Values of sensitivity,specificity,and ability to correctly classify UC,according to activity,were 83.33%,83.33% and 83.33%,respectively.The AUC of the ROC curve to assess the ability of this molecule to discriminate between active vs inactive UC was 0.92(0.86-0.97,P < 0.0001).The serum levels of sST2 in patients with UC significantly correlated with endoscopic and histo-pathological scores(r = 0.76 and r = 0.67,P < 0.0001,respectively),and with the pro-inflammatory cytokine,tumor necrosis factor-α(r = 0.69 and r = 0.61,respectively,P < 0.0001).Interestingly,we found a direct correlation between total intestinal ST2 content and serum levels of sST2,adjusted to endoscopic activity score in patients with mild(r = 0.44,P = 0.004),moderate(r = 0.59,P = 0.002) and severe disease(r = 0.82,P = 0.002).Only patients with inactive UC showed no significant correlation(r = 0.45,P = 0.267).CONCLUSION:sST2 levels correlated with disease severity and inflammatory cytokines,are able to differentiate active from inactive UC and might have a role as a biomarker.David Díaz-Jiménez Lucía E Núez Caroll J Beltrán Enzo Candia Cristóbal Suazo Manuel varez-Lobos María-Julieta González Marcela A Hermoso Rodrigo Quera 2011World Journal of Gastroenterology2011,17,17:8
4Liver disease and erythropoietic protoporphyria:A concise review显示文摘The porphyries are a group of metabolic disorders characterized by deficiencies in the activity of enzymes involved in the biosynthesis of heme.In erythropoietic protoporphyria(EPP),in the majority of cases an autosomal dominant disease,there is a mutation of the gene that encodes ferrochelatase(FECH).FECH deficiency is associated with increased concentrations of protoporphyrin in erythrocytes,plasma,skin and liver.The prevalence of this inherited disorder oscillates between 1:75 000 and 1:200 000.Clinical manifestations of EPP appear in early infancy upon first exposure to the sun.Nevertheless,approximately 5%-20% of patients with EPP develop liver manifestations.Retention of protoporphyrin in the liver is associated with cholestatic phenomena and oxidative stress that predisposes to hepatobiliary disease of varying degrees of severity,such as cholelithiasis,mild parenchymal liver disease,progressive hepatocellular disease with end-stage liver disease and acute liver failure.Liver damage is the major risk in EPP patients,so surveillance and frequent clinical and biochemical liver follow-up is mandatory.The diagnostic approach consists in detecting increased levels of protoporphyrin,decreased activity of FECH and genetic analysis of the FECH gene.A variety of nonsurgical therapeutic approaches have been adopted for the management of EPP associated with liver disease,but none of these has been shown to be unequivocally efficacious.Nevertheless,some may have a place in preparing patients for liver transplantation.Liver transplantation does not correct the constitutional deficiency of FECH.Consequently,there is a risk of recurrence of liver disease after liver transplantation as a result of continuing overproduction of protoporphyrin.Some authors recommend that bone marrow transplantation should be considered in liver allograft recipients to prevent recurrence of hepatic disease.María José Casanova-González María Trapero-Marugán E Anthony Jones Ricardo Moreno-Otero 2010World Journal of Gastroenterology2010,16,36:7

6Timing, method and discontinuation of hydrocortisone administration for septic shock patients显示文摘AIM To characterize the prescribing patterns for hydrocortisone for patients with septic shock and perform an exploratory analysis in order to identify the variables associated with better outcomes.METHODS This prospective cohort study included 59 patients with septic shock who received stress-dose hydrocortisone.It was performed at 2 critical care units in academic hospitals from June 1st, 2015, to July 31 st, 2016. Demographic data, comorbidities, medical management details, adverse effects related to corticosteroids, and outcomes were collected after the critical care physician indicated initiation of hydrocortisone. Univariate comparison between continuous and bolus administration of hydrocortisone was performed, including multivariate analysis, as well as Kaplan-Meier analysis to compare the proportion of shock reversal at 7 d after presentation. Receiver operating characteristic(ROC) curves determined the best cut-off criteria for initiation of hydrocortisone associated with the highest probability of shock reversal. We addressed the effects of the taper strategy for discontinuation of hydrocortisone, noting risk of shock relapse and adverse effects.RESULTS All-cause 30-d mortality was 42%. Hydrocortisone was administered as a continuous infusion in 54.2% of patients; time to reversal of shock was 49 h longer in patients who were given a bolus administration [59 h(range, 47.5-90.5) vs 108 h(range, 63.2-189); P = 0.001]. The maximal dose of norepinephrine after initiation of hydrocortisone was lower in patients on continuous infusion [0.19 μg/kg per minute(range, 0.11-0.28 μg)] compared with patients who were given bolus [0.34 μg/kg per minute(range, 0.16-0.49); P = 0.004]. Kaplan-Meier analysis revealed a higher proportion of shock reversal at 7 d in patients with continuous infusion compared to those given bolus(83% vs 63%; P = 0.004). There was a good correlation between time to initiation of hydrocortisone and time to reversal of shock(r = 0.80; P < 0.0001); ROC curve analysis revealed that the best criteria for prediction of shock reversal was a time to initiation of hydrocortisone of ≤ 13 h after administration of norepinephrine, with an area under the curve of 0.81(P < 0.001). The maximal dose of norepinephrine at initiation of hydrocortisone with the highest association with shock reversal was ≤ 0.28 μg/kg per minute, with an area under the curve of 0.75(P = 0.0002). On a logistic regression model, hydrocortisone taper was not associated with a lower risk of shock relapse(RR = 1.29; P = 0.17) but was related to a higher probability of hyperglycemia [odds ratio(OR), 5.3; P = 0.04] and hypokalemia(OR = 10.6; P = 0.01). CONCLUSION Continuous infusion of hydrocortisone could hasten the resolution of septic shock compared to bolus administration. Earlier initiation corresponds with a higher probability of shock reversal. Tapering strategy is unnecessary.Miguel A Ibarra-Estrada Quetzalcóatl Chávez-Pe?a Claudia I Reynoso-Estrella Jorge Rios-Zerme?o Pável E Aguilera-González Miguel A García-Soto Guadalupe Aguirre-Avalos 2017World Journal of Critical Care Medicine2017,6,1:4
