2Covalently closed-circular hepatitis B virus DNA reduction with entecavir or lamivudine显示文摘AIM: To investigate the reduction in hepatitis B virus(HBV) covalently closed-circular DNA(ccc DNA) with entecavir(ETV) or lamivudine(LAM). METHODS: This analysis included patients who had participated in the randomized Phase Ⅲ study ETV-022 comparing ETV vs LAM in nucleos(t)ide-naive, HBe Agpositive patients. Patients received ETV(0.5 mg daily) or LAM(100 mg daily) for a minimum of 52 wk. Patients were eligible to participate in this sub-study if they had paired biopsies at baseline and week 48 with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA. The main objective was to compare changes in hepatic HBV ccc DNA and total hepatic HBV DNA at week 48 of ETV or LAM treatment, which was a secondary endpoint of study ETV-022. Additional post hoc analyses included linear regression analyses to assess associations of baseline levels and on-treatment changes of ccc DNA with other baseline factors [sex,age, serum HBV DNA, alanine aminotransferase(ALT), Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBV genotype], or ontreatment factors(changes from baseline at week 48 in serum HBV DNA, ALT, Knodell necroinflammatory score, Ishak fibrosis score, total hepatic HBV DNA, and HBe Ag loss at week 48).RESULTS: Overall, 305 patients(ETV = 159; LAM = 146) of ETV-022 had paired baseline and week 48 liver biopsies with evaluable measurements for hepatic HBV ccc DNA and total hepatic HBV DNA, and were included in this analysis. Baseline demographics and disease characteristics were comparable between the two arms. After 48 wk, ETV resulted in significantly greater reductions in hepatic HBV ccc DNA [-0.9 log10 copies/human genome equivalent(HGEq) vs-0.7 log10 copies/HGEq; P = 0.0033] and total hepatic DNA levels(-2.1 log10 copies/HGEq vs-1.6 log10 copies/HGEq; P < 0.0001) than LAM. Virologic, biochemical, and histologic response rates at week 48 were also greater with ETV than with LAM. Baseline HBV ccc DNA levels were positively associated with baseline levels of serum HBV DNA and total hepatic HBV DNA, and negatively associated with HBV genotype F. On-treatment changes in HBV ccc DNA levels were negatively associated with baseline levels of serum HBV DNA and baseline ALT, and were positively associated with on-treatment changes in the levels of serum HBV DNA, total hepatic HBV DNA levels, and ALT, change in Knodell necroinflammatory score, and HBe Ag loss.CONCLUSION: Forty-eight weeks of ETV resulted in greater reductions in ccc DNA and total hepatic HBV DNA than LAM, but long-term therapy may be needed for ccc DNA elimination.Scott Bowden Stephen Locarnini Ting-Tsung Chang You-Chen Chao Kwang-Hyub Han Robert G Gish Robert A de Man Miao Yu Cyril Llamoso Hong Tang 2015World Journal of Gastroenterology2015,21,15:11

4Epigenetic profiles of pre-diabetes transitioning to type 2 diabetes and nephropathy显示文摘AIM: To examine DNA methylation profiles in a longitudinal comparison of pre-diabetes mellitus(Pre-DM) subjects who transitioned to type 2 diabetes mellitus(T2DM).METHODS: We performed DNA methylation study in bisulphite converted DNA from Pre-DM(n = 11) at baseline and at their transition to T2 DM using Illumina Infinium Human Methylation27 Bead Chip, that enables the query of 27578 individual cytosines at Cp G loci throughout the genome, which are focused on the promoter regions of 14495 genes.RESULTS: There were 694 Cp G sites hypomethylated and 174 Cp G sites hypermethylated in progression from Pre-DM to T2 DM, representing putative genes involved in glucose and fructose metabolism, inflammation, oxidative and mitochondrial stress, and fatty acid metabolism. These results suggest that this high throughput platform is able to identify hundreds of prospective Cp G sites associated with diverse genes that may reflect differences in Pre-DM compared with T2 DM. In addition, there were Cp G hypomethylation changes associated with a number of genes that may be associated with development of complications of diabetes, such as nephropathy. These hypomethylation changes were observed in all of the subjects.CONCLUSION: These data suggest that some epigenomic changes that may be involved in the progression of diabetes and/or the development of complications may be apparent at the Pre-DM state or during the transition to diabetes. Hypomethylation of a number of genes related to kidney function may be an early marker for developing diabetic nephropathy.Thomas A Vander Jagt Monica H Neugebauer Marilee Morgan Donald W Bowden Vallabh O Shah 2015World Journal of Diabetes2015,6,9:5

10术中应用荧光素钠有利于胶质母细胞瘤浸润边缘的手术切除(英文)显示文摘Objective Extent of resection is an important prognostic factor in patients undergoing surgery for glioblastoma( GBM).Recent evidence suggests that intravenously administered fluorescein sodium associates with tumor tissue,facilitating safe maximal resection of GBM. In this study,the authors evaluate the safety and utility of intraoperative fluorescein guidance for the prediction of histopathological alteration both in the contrast-enhancing( CE) regions,where this relationship has been established,and into the nonCE( NCE),diffusely infiltrated margins. Methods Thirty-two patients received fluorescein sodium( 3 mg/kg) intravenously prior to resection. Fluorescence was intraoperatively visualized using a Zeiss Pentero surgical microscope equipped with a YELLOW 560 filter.Stereotactically localized biopsy specimens were acquired from CE and NCE regions based on preoperative MRI in conjunction with neuronavigation. The fluorescence intensity of these specimens was subjectively classified in real time with subsequent quantitative image analysis,histopathological evaluation of localized biopsy specimens,and radiological volumetric assessment of the extent of resection.Results Bright fluorescence was observed in all GBMs and localized to the CE regions and portions of the NCE margins of the tumors,thus serving as a visual guide during resection. Gross-total resection( GTR) was achieved in 84% of the patients with an average resected volume of 95%,and this rate was higher among patients for whom GTR was the surgical goal( GTR achieved in 93. 1% of patients,average resected volume of 99. 7%). Intraoperative fluorescein staining correlated with histopathological alteration in both CE and NCE regions,with positive predictive values by subjective fluorescence evaluation greater than 96% in NCE regions. Conclusions Intraoperative administration of fluorescein provides an easily visualized marker for glioma pathology in both CE and NCE regions of GBM. These findingssupport the use of fluorescein as a microsurgical adjunct for guiding GBM resection to facilitate safe maximal removal.Neira JA Ung TH Sims J Malone HR Chow DS Samanamud JL Zanazzi GJ Guo X Bowden SG Zhao B Sheth SA McKhann GM 2nd Sisti MB Canoll P D'Amico RS Bruce JN 2016中华神经外科疾病研究杂志2016,15,5:2

12Heart rate is an independent predictor of all-cause mortality in individuals with type 2 diabetes: The diabetes heart study显示文摘AIM To assess the association of resting heart rate with allcause and cardiovascular disease(CVD) mortality in the Diabetes Heart Study(DHS).METHODS Out of a total of 1443 participants recruited into the DHS, 1315 participants with type 2 diabetes who were free of atrial fibrillation and supraventricular tachycardia during the baseline exam were included in this analysis. Heart rate was collected from baseline resting electrocardiogram and mortality(all-cause and CVD) was obtained from state and national death registry. Kaplan-Meier(K-M) and Cox proportional hazard analyses were used to assess the association.RESULTS The mean age, body mass index(BMI) and systolic blood pressure(SBP) of the cohort were 61.4 ± 9.2 years, 32.0 ± 6.6 kg/m2, and 139.4 ± 19.4 mmHg respectively. Fiftysix percent were females, 85% were whites, 15% were blacks, 18% were smokers. The mean ± SD heart rate was 69.8(11.9) beats per minute(bpm). After a median follow-up time of 8.5 years(maximum follow-up time is 14.0 years), 258 participants were deceased. In K-M analysis, participants with heart rate above the median had a significantly higher event rate compared with those below the median(log-rank P = 0.0223). A one standard deviation increase in heart rate was associated with allcause mortality in unadjusted(hazard ratio 1.16, 95%CI: 1.03-1.31) and adjusted(hazard ratio 1.20, 95%CI: 1.05-1.37) models. Similar results were obtained with CVD mortality as the outcome of interest.CONCLUSION Heart rate is an independent predictor of all-cause mortality in this population with type 2 diabetes. In this study, a 1-SD increase in heart rate was associated with a 20% increase in risk suggesting that additional prognostic information may be gleaned from this ubiquitously collected vital sign.Sameer Prasada Cameron Oswalt Phyllis Yeboah Georgia Saylor Donald Bowden Joseph Yeboah 2018World Journal of Diabetes2018,9,1:2
