World Journal of Gastroenterology 2015年第35期21卷 10234-10241页

作者： jae jin hwang Dong Ho Lee Ae-Ra Lee Hyuk Yoon Cheol Min Shin Young Soo Park Nayoung Kim Department of Internal Medicine Seoul National University Bundang Hospital

AIM: To evaluate the efficacy of moxifloxacin-based sequential therapy(MBST) versus hybrid therapy as a first-line treatment for Helicobacter pylori(H. pylori) ***: From August 2014 to January 2015, 284 patients with confirmed H. pylori infection were randomized to receive a 14-d course of MBST(MBST group, n = 140) or hybrid(Hybrid group, n = 144) therapy. The MBST group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 7 d, followed by 20 mg rabeprazole and 500 mg metronidazole twice daily, and 400 mg moxifloxacin once daily for 7 d. The Hybrid group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 14 d. In addition, the Hybrid group received 500 mg metronidazole and 500 mg clarithromycin twice daily for the final 7 d. Successful eradication of H. pylori infection was defined as a negative 13C-urea breath test 4 wk after the end of treatment. Patient compliance was defined as "good" if drug intake was at least 85%. H. pylori eradication rates, patient compliance with treatment, and adverse event rates were ***: The eradication rates in the intention-totreat(ITT) analysis were 91.4%(128/140; 95%CI: 90.2%-92.9%) in the MBST group and 79.2%(114/144; 95%CI: 77.3%-80.7%) in the Hybrid group(P = 0.013). The eradication rates in the perprotocol(PP) analysis were 94.1%(128/136; 95%CI: 92.9%-95.6%) in the MBST group and 82.6%(114/138; 95%CI: 80.6%-84.1%) in the Hybrid group(P = 0.003). The H. pylori eradication rate in the MBST group was significantly higher than that of the Hybrid group for both the ITT(P = 0.013) and the PP analyses(P = 0.003). Both groups exhibited full compliance with treatment(MBST/Hybrid group: 100%/100%). The rate of adverse events was 11.8%(16/136) and 19.6%(27/138) in the MBST and Hybrid group, respectively(P = 0.019). The majority of adverse events were mild-to-moderate in intensity; none were severe enough to cause discontinuation of treatment in either ***: MBST was more effecti

AIM: To investigate the eradication rate and histological changes after Helicobacter pylori(H. pylori) eradication treatment following subtotal gastrectomy for gastric ***: A total of 610 patients with H. pylori infection who had undergone surgery for either early or advanced gastric adenocarcinoma between May 2004 and December 2010 were retrospectively studied. A total of 584 patients with proven H. pylori infection after surgery for gastric cancer were enrolled in this study. Patients received a seven day standard triple regimen as first-line therapy and a 10 d bismuthcontaining quadruple regimen as second-line therapy in cases of eradication failure. The patients underwent an esophagogastroduodenoscopy(EGD) between six and 12 mo after surgery, followed by annual EGDs. A further EGD was conducted 12 mo after confirming the result of the eradication and the histological changes. A gastric biopsy specimen for histological examination and Campylobacter-like organism testing was obtained from the lesser and greater curvature of the corpus of the remnant stomach. Histological changes in the gastric mucosa were assessed using the updated Sydney system before eradication therapy and at follow-up after 12 ***: Eradication rates with the first-line and second-line therapies were 78.4%(458/584) and 90%(36/40), respectively, by intention-to-treat analysis and 85.3%(458/530) and 92.3%(36/39), respectively, by per-protocol analysis. The univariate and multivariate analyses revealed that Billroth Ⅱ surgery was an independent factor predictive of eradication success in the eradication success group(OR = 1.53, 95%CI: 1.41-1.65, P = 0.021). The atrophy and intestinal metaplasia(IM) scores 12 mo after eradication were significantly lower in the eradication success group than in the eradication failure group(0.25 ± 0.04 vs 0.47 ± 0.12, P = 0.023; 0.27 ± 0.04 vs 0.51 ± 0.12, P = 0.015, respectively).

In spite of the high potential economic feasibility of the tandem solar cells consisting of the halide perovskite and the kesterite Cu2ZnSn(S,Se)4(CZTSSe),they have rarely been demonstrated due to the difficulty in implementing solution-processed perovskite top cell on the rough surface of the bottom ***,we firstly demonstrate an efficient monolithic two-terminal perovskite/CZTSSe tandem solar cell by significantly reducing the surface roughness of the electrochemically deposited CZTSSe bottom *** surface roughness(R_(rms))of the CZTSSe thin film could be reduced from 424 to 86 nm by using the potentiostatic mode rather than using the conventional galvanostatic mode,which can be further reduced to 22 nm after the subsequent ion-milling *** perovskite top cell with a bandgap of 1.65 eV could be prepared using a solution process on the flattened CZTSSe bottom cell,resulting in the efficient perovskite/CZTSSe tandem solar *** the current matching between two subcells involving the thickness control of the perovskite layer,the best performing tandem device exhibited a high conversion efficiency of 17.5%without the hysteresis effect.
