3Outcomes of furazolidone-and amoxicillin-based quadruple therapy for Helicobacter pylori infection and predictors of failed eradication显示文摘AIM To evaluate the outcomes of furazolidone-and amoxicillin-based quadruple therapy for treatment of Helicobacter pylori(H. pylori) infection and identify predictors of failed eradication.METHODS Patients with H. pylori infection treated with furazolidone, amoxicillin, bismuth, and proton pump inhibitor therapy(January 2015 to December 2015) who received the ^(13)C-urea breath test > 4 wk after treatment were evaluated. Demographic and clinical data including prior H. pylori treatment attempts, medication adherence, alcohol and cigarette consumption during therapy, and treatment-related adverse events were recorded by reviewing medical records and telephone surveys. H. pylori eradication rates for overall and subgroups were evaluated. Multivariate analysis was performed to identify independent predictors of failed H. pylori eradication.RESULTS Of the 992 patients treated and retested for H. pylori infection, the overall eradication rate was 94.5% [95% confidence interval(CI): 94.1%-95.9%]. H. pylori eradication rate of primary therapy was 95.0%(95%CI: 93.5%-96.5%), while that of rescue therapy was 91.3%(95%CI: 86.8%-95.8%). Among the 859 patients who completed the study protocol, 144(17%) reported treatment-related adverse events including 24(3%) leading to premature discontinuation. On multivariate analysis, poor medication adherence [adjusted odds ratio(AOR) = 6.7, 95%CI: 2.8-15.8], two or more previous H. pylori treatments(AOR = 7.4, 95%CI: 2.2-24.9), alcohol consumption during therapy(AOR = 4.4, 95%CI: 1.5-12.3), and possibly smoking during therapy(AOR = 1.9, 95%CI: 0.9-4.3) were associated with failed H. pylori eradication. CONCLUSION Furazolidone-and amoxicillin-based quadruple therapy for H. pylori infection in an area with a high prevalence of clarithromycin resistance demonstrated high eradication rates as primary and rescue therapies with a favorable safety profile. Patient education targeting abstinence from alcohol during therapy and strict medication adherence may further optimize H. pylori eradication.Ya-Wen Zhang Wei-Ling Hu Yuan Cai Wen-Fang Zheng Qin Du John J Kim John Y Kao Ning Dai Jian-Min Si 2018World Journal of Gastroenterology2018,24,40:18

7HBsAg loading on dendritic cells in patients with chronic hepatitis B: expressions of phenotypic molecules显示文摘BACKGROUND: The antigen reducing ability of dentritic cells (DCs), a kind of antigen presenting cells (APCs) initiating immune response, is associated with the specific immune tolerance of chronic hepatitis B(CHB) patients. However, the dysfunction of DCs can be possibly reversed by the stimulation of antigen peptides. In this study, DCs were cultured from peripheral blood monocytes (PBMCs) in patients with CHB in vitro, and the expression of phenotypic molecules on DCs loaded by different concentrations of HBsAg was observed. METHODS: Forty patients with CHB were divided randomly into 4 groups(10 patients in each group). PBMCs were isolated, and DCs were cultured after addition of granulocyte/macrophage colony-stimulating factor (GMCSF) and interleukin 4(IL-4). On the 9th day, DCs of the experimental groups were loaded at HBsAg concentrations of 2.5mg/L, 5mg/L and 10mg/L for 24 hours, whereas those of the control group were not loaded. An electron microscope was used to analyze the morphological changes of the DCs. The expression of phenotypic molecules on DCs in different groups was detected with flow cytometry. RESULTS: A combination of GM-CSF and IL-4 produced DCs from PBMCs in patients with CHB after being cultured for 9 days, whose morphological changes were tested by an electron microscope. The expression of phenotypic molecules on DCs in the control group was as low as CD83 (8.02±3.99)%, CD80(8.77±2.06)%, and MHC-DR (14.05±2.66)%. Loaded by different concentrations of HBsAg, the up-regulation of phenotypic molecules on DCs was found, with CD83(18.35±2.93)%, CD80(42.63±7.15)% and MHC-DR(47.49±6.59)% in 2.5mg/L HBsAg loading group, CD83(17.88±3.12)%, CD80(45.24± 10.93)% and MHC-DR(47.07±8.52)% in 5mg/L HBsAg loading group and CD83(16.74±2.86)%, CD80(44.59±6.99)% and MHC-DR(48.59±7.42)% in 10mg/L HBsAg loading group, respectively. Compared with the control group, the phenotypic molecules in the experimental groups were all different significantly (P<0.01), but among them, there were no differences (P>0.05). CONCLUSIONS: DCs cultured from PBMCs in the patients with CHB under the conditions of GM-CSF and IL-4 present on the typical dendritic morphology but are immature for expressing low phenotypic molecules. Loaded by different concentrations of HBsAg, the immature DCs can differentiate to mature DCs for expressing increasing phenotypic molecules.Hua-Sheng Tong, Yi Zhang, Keng Yuan and Xin-Wen Fu Institute for Digestive Disease, Affiliated Nanfang Hospital of Nanfang Medical University, Guangzhou 510515, China Department of Infectious Disease, First Affiliated Hospital of Jiangxi Medical College Key Oncolog’y Laboratory of Institute for Medical Science, Jiangxi Province and Department of Laboratory, Jiangxi Province People’s Hospital, Nanchang 330000, China 2006Hepatobiliary & Pancreatic Diseases International2006,5,1:4
8Dynamical analysis of mesoscale eddy-induced ocean internal waves using linear theories显示文摘This study aims to explore generation mechanisms of the ocean internal wave using the dynamical analysis methods based on linear theories.Historical cruise measurements and recent synthetic aperture radar(SAR)observations of mesoscale eddies with diameter of several tens of kilometers to hundreds of kilometers show that the internal wave packets with wavelength of hundreds of meters to kilometer exist inside the mesoscale eddies.This coexistence phenomenon and inherent links between the two different scale processes are revealed in the solutions of governing equations and boundary conditions for the internal wave disturbance with a horizontally slowly variable amplitude in a cylindrical coordinate system.The theoretical solutions indicate that the instability of eddy current field provides the dynamical mechanism to internal wave generation.The derived dispersion relation indicates that the internal wave propagation is modified by the eddy current field structure.The energy equation of the internal waves clearly shows the internal wave energy increment comes from the eddy.The theoretical models are used to explain the observation of the mesoscale eddy-induced internal waves off the Norwegian coast.The two-dimensional waveform solution of the anticyclonic eddy-induced internal wave packet appears as ring-shaped curves,which contains the typical features of eddy stream lines.The comparison of theoretical solutions to the structure of the internal wave packets on SAR image shows a good agreement on the major features.XU Qing ZHENG Quanan LIN Hui LIU Yuguang SONG Y Tony YUAN Yeli 2008Acta Oceanologica Sinica2008,27,3:3

13Quality control measures for lowering the seroconversion rate of hemodialysis patients with hepatitis B or C virus显示文摘BACKGROUND: Hemodialysis (HD) patients are at high risk of infection by hepatitis B virus (HBV) or hepatitis C virus (HCV). The present study was designed to determine the impact of quality control measures on the prevention of transmission of blood-borne viruses. METHODS: A total of 6182 adult maintenance HD patients from all HD units in Zhejiang Province were recruited on January 1, 2007. The baseline demographic and clinical characteristics were recorded and all patients were followed up until death or survival at 4 years later. The Quality Control Standards of Hemodialysis were gradually implemented in HD units. The HBV or HCV seroconversion rates of the recruited patients were calculated and compared every year during the observation period. RESULTS: The prevalence of HBV was 8.3% at the beginning of the study, and 6.6% for HCV. With the implementation of the HD quality control measures, the HBV seroconversion rate tended to decrease year by year (χ 2 =6.620, P=0.085), and the HCV seroconversion rate decreased significantly (χ 2 =10.41, P=0.015). Compared with the data in 2007, the HBV seroconversion rate (χ 2 =4.204, P=0.040, relative risk ratio 0.393, 95% CI 0.156-0.991) and the HCV seroconversion rate (χ 2 =7.373, P=0.007, relative risk ratio 0.386, 95% CI 0.189-0.787) decreased significantly in 2010. CONCLUSION: Quality control measures for HD decreased the seroconversion rates of HBV or HCV in HD patients, showing that updated quality control measures reduce the risk for transmission of blood-borne viruses in the HD population.Jing Yuan,Yi Yang, Fei Han, Ping Zhang, Xiao-Ying Du, Hua Jiang and Jiang-Hua Chen The Kidney Disease Center, First Affiliated Hospital, Zhejiang University School of Medicine (Yuan J, Yang Y, Han F, Zhang P, Du XY, Jiang H and Chen JH) and Hemodialysis Quality Control Center of Zhejiang Province (Yuan J, Zhang P, Du XY and Chen JH), Hangzhou 310003, China 2012Hepatobiliary & Pancreatic Diseases International2012,11,3:2
