| 1 | HCV-RNA positivity in peripheral blood mononuclear cells of patients with chronic HCV-infection: does it really mean viral replication?显示文摘AIM To analyze the association of HCV-RNA with peripheral blood mononuclear cells (PBMC)and to answer the question whether HCV-RNA positivity in PBMC is due to viral replication,METHODS HCV-RNA was monitored in serumand PBMC preparations from 15 patients with chronic HCV infection before, during and after an IFN-α therapy using a nested RT/ PCRtechnique. In a second approach, PBMC from healthy donors were incubated in HCV positive plasma.RESULTS In the IFN-α responding patients,HCV-RNA disappeared first from total RNApreparations of PBMC and then from serum. In contrast, in relapsing patients, HCV-RNAreappeared first in serum and then in PBMC. A quantitative analysis of the HCV-RNAconcentration in serum was performed before and after transition from detectable to nondetectable HCV-RNA in PBMC-RNA and vice versa. When HCV-RNA was detectable in PBMCpreparations, the HCV concentration in serum was significantly higher than the serum HCV-RNA concentration when HCV-RNA in PBMC was not detectable. Furthermore, at no time during the observation period was HCV specific RNA observed in PBMC, if HCV-RNA in serum was under the detection limit. Incubation of PBMCfrom healthy donors with several dilutions of HCV positive plasma for two hours showed a concentration-dependent PCR-positivity for HCV-RNA in reisolated PBMC.CONCLUSION The detectability of HCV-RNA in total RNA from PBMC seems to depend on the HCV concentration in serum. Contamination or passive adsorption by circulating virus could be the reason for detection of HCV-RNA in PBMCpreparations of chronically infected patients. | Volker Meier Sabine Mihm Perdita Wietzke-Braun Guliano Ramadori | 2001 | World Journal of Gastroenterology2001,7,2: | 29 |
| 2 | Current treatment of ulcerative colitis显示文摘Ulcerative colitis (UC) is a chronic disease featuring re- current inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complica- tions of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed. This article is intended to give a general, practice-orientated overview of the key issues in ulcerative colitis treatment. Recommendations are based on published consensus guidelines derived from national and international guidelines on the treatment of ulcerative colitis. | Johannes Meier Andreas Sturm | 2011 | World Journal of Gastroenterology2011,17,27: | 28 |

| 4 | Increased susceptibility for intrahepatic cholestasis of pregnancy and contraceptive-induced cholestasis in carriers of the 1331T>C polymorphism in the bile salt export pump显示文摘AIM: To study the association of three common ABCB11 and ABCC2 polymorphisms (ABCB11: 1331T>C V444A; ABCC2: 3563T>A V1188E and 4544G>A C1515Y) with intrahepatic cholestasis of pregnancy (ICP) and contraceptive-induced cholestasis (CIC). METHODS: ABCB11 and ABCC2 genotyping data were available from four CIC patients and from 42 and 33 ICP patients, respectively. Allele-frequencies of the studied polymorphisms were compared with those in healthy pregnant controls and Caucasian individuals. Furthermore, serum bile acid levels were correlated with the presence or absence of the 1331 C allele.RESULTS: The ABCB11 1331T>C polymorphism was significantly more frequent in cholestatic patients than in pregnant controls: C allele 76.2% (CI, 58.0-94.4) vs 51.3% (CI 35.8-66.7), respectively (P = 0.0007); and CC allele 57.1% (CI 36.0-78.3) vs 20% (CI 7.6-32.4), respectively (P = 0.0065). All four CIC patients were homozygous carriers of the C allele. In contrast, none of the studied ABCC2 polymorphism was overrepresented in ICP or CIC patients. Higher serum bile acid levels were found in carriers of the 1331CC genotype compared to carriers of the TT genotype.CONCLUSION: Our data support a role for the ABCB11 1331T>C polymorphism as a susceptibility factor for the ←←← development of estrogen-induced cholestasis, whereas no such association was found for ABCC2. Serum bile acid and γ-glutamyl transferase levels might help to distinguish ABCB4- and ABCB11-related forms of ICP and CIC. | Yvonne Meier Tina Zodan Carmen Lang Roland Zimmermann Gerd A Kullak-Ublick Peter J Meier Bruno Stieger Christiane Pauli-Magnus | 2008 | World Journal of Gastroenterology2008,14,1: | 20 |
| 5 | Combination of 'low-dose' ribavirin and interferon alfa-2a therapy followed by interferon alfa-2a monotherapy in chronic HCV-infected nonresponders and relapsers after interferon alfa-2a monotherapy显示文摘AIM To report on the efficacy, safety and tolerability of interferon alfa-2a combined with a 'low dose' of ribavirin for relapsers and non responders to alpha interferon monotherapy.METHODS Thirty-four chronic hepatitis C virus-infected non-responders to interferon alfa2a monotherapy (a course of at least 3 months treatment) and 13 relapsers to interferon alfa 2a monotherapy (a dose of 3 to 6 million units three times per week for at least 20 weeks but not more than 18 months) were treated with the same dose of interferon alfa-2a used before (3 to 6 million units three times per week) and ribavirin (10 mg/ kg daily) for 6 months. In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be performed. | Perdita Wietzke-Braun Volker Meier Felix Braun Giuliano Ramadori | 2001 | World Journal of Gastroenterology2001,7,2: | 19 |

| 7 | Nonlinear optics in all-dielectric nanoantennas and metasurfaces:a review显示文摘Free from phase-matching constraints,plasmonic metasurfaces have contributed significantly to the control of optical nonlinearity and enhancement of nonlinear generation efficiency by engineering subwavelength meta-atoms.However,high dissipative losses and inevitable thermal heating limit their applicability in nonlinear nanophotonics.All-dielectric metasurfaces,supporting both electric and magnetic Mie-type resonances in their nanostructures,have appeared as a promising alternative to nonlinear plasmonics.High-index dielectric nanostructures,allowing additional magnetic resonances,can induce magnetic nonlinear effects,which,along with electric nonlinearities,increase the nonlinear conversion efficiency.In addition,low dissipative losses and high damage thresholds provide an extra degree of freedom for operating at high pump intensities,resulting in a considerable enhancement of the nonlinear processes.We discuss the current state of the art in the intensely developing area of all-dielectric nonlinear nanostructures and metasurfaces,including the role of Mie modes,Fano resonances,and anapole moments for harmonic generation,wave mixing,and ultrafast optical switching.Furthermore,we review the recent progress in the nonlinear phase and wavefront control using all-dielectric metasurfaces.We discuss techniques to realize alldielectric metasurfaces for multifunctional applications and generation of second-order nonlinear processes from complementary metal–oxide–semiconductor-compatible materials. | Basudeb Sain Cedrik Meier Thomas Zentgraf | 2019 | Advanced Photonics2019,1,2: | 17 |
| 8 | Endoscopic full-thickness resection: current status显示文摘Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However,those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection(EFTR) is an evolving technique,which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices. | Arthur Schmidt Benjamin Meier Karel Caca | 2015 | World Journal of Gastroenterology2015,21,31: | 14 |
| 9 | 关于西罗莫司和紫杉醇洗脱支架用于新发冠状动脉病变的随机对照试验:REALITY试验显示文摘Context: Compared with bare metal stents, sirolimus-elut-ing and paclitaxel-eluting stents have been shown to markedly improve angiographic and clinical outcomes after percutaneous coronary revascularization, but their performance in the treatment of de novo coronary lesions has not been compared in a prospective multicenter study. Objective: To compare the safety and efficacy of sirolimus-eluting vs paclitaxel-eluting coronary stents. Design: Prospective, randomized comparative trial(the REALITY trial) conducted between August 2003 and February 2004, with angiographic follow-up at 8 months and clinical follow-up at 12 months. Setting: Ninety hospitals in Europe, Latin America, and Asia. Patients: A total of 1386 patients(mean age, 62.6 years; 73.1% men; 28.0% with diabetes)with angina pectoris and 1 or 2 de novo lesions(2.25-3.00 mm in diameter) in native coronary arteries. Intervention: Patients were randomly assigned in a 1 ∶ 1 ratio to receive a sirolimus-eluting stent(n=701) or a paclitaxel-eluting stent(n=685). Main Outcome Measures: The primary end point was in-lesion binary restenosis(presence of a more than 50% luminal diameter stenosis) at 8 months. Secondary end points included 1-year rates of target lesion and vessel revascularization and a composite end point of cardiac death, Q-wave or non-Q-wave myocardial infarction, coronary artery bypass graft surgery, or repeat target lesion revascularization. Results: In-lesion binary restenosis at 8 months occurred in 86 patients(9.6% ) with a sirolimus-eluting stent vs 95(11.1% ) with a paclitaxel-eluting stent(relative risk [RR], 0.84; 95% confidence interval [CI], 0.61-1.17; P=.31). For sirolimus- vs paclitaxel-eluting stents, respectively, the mean(SD) in-stent late loss was 0.09(0.43) mm vs 0.31(0.44) mm(difference,-0.22 mm; 95% CI,-0.26 to-0.18 mm; P<.001), mean(SD) in-stent diameter stenosis was 23.1% (16.6% ) vs 26.7% (15.8% )(difference,-3.60% ; 95% CI,-5.12% to-2.08% ; P< .001), and the number of major adverse cardiac events at 1 year was 73(10.7% ) vs 76(11.4% )(RR, 0.94; 95% CI, 0.69-1.27; P=.73). Conclusion: In this trial comparing sirolimus- and paclitaxel-eluting coronary stents, there were no differences in the rates of binary restenosis or major adverse cardiac events.

| 11 | Measurement of calprotectin in ascitic fluid to identify elevated polymorphonuclear cell count显示文摘AIM: To evaluate the diagnostic capability of calprotectin in ascitic fluid for detecting a polymorphonuclear (PMN) cell count > 250/μL ascites. METHODS: In this prospective observational study, a total of 130 ascites samples were analysed from 71 consecutive patients referred for paracentesis. Total and differential leukocyte cell counts were determined manually with a Neubauer chamber and gentianviolet stain. Calprotectin was measured in 1 mL ascetic fluid by enzyme-linked immunosorbent assay (ELISA) and a point-of-care (POC) lateral flow assay with the Quantum Blue Reader (Bühlmann Laboratories). All measurements were carried out in a central laboratory by senior personnel blinded to patient history. A PMN count > 250/μL was the primary endpoint of the study. The diagnostic value of ascitic calprotectin measurement was assessed by comparing to the final diagnosis of each patient that had been adjudicated by investigators blinded to calprotectin values. RESULTS: The PMN count was > 250/μL in 19 samples (14.6%) from 15 patients (21.1%) and varied widely among the study population (range 10-19 800/mL and 1-17 820/mL, respectively). Spontaneous bacterial peritonitis (SBP) was the final diagnosis in four patients (5.6%). All patients with PMN ≤ 250/μL had negative bacterial culture. PMN count was elevated in five patients with peritoneal carcinomatosis, three with lymphoma, one with neuroendocrine carcinoma, and two with secondary peritonitis due to abdominal perforation. PMN cell counts correlated with ascitic calprotectin values (Spearman's rho; r = 0.457 for ELISA, r = 0.473 for POC). A considerable range of ascitic calprotectin concentrations was detected by ELISA [median 0.43 μg/mL, interquartile range (IQR) 0.23-1.23 (range 0.10-14.93)] and POC [median 0.38 μg/mL, IQR 0.38-0.56 (range 0.38-13.31)]. Ascitic calprotectin levels were higher in samples with PMN > 250/μL, by both ELISA [median (IQR) 2.48 μg/mL (1.61-3.65) vs 0.10 μg/mL (0.10-0.36), P < 0.001] and POC [2.78 μg/mL (2.05-5.37) vs 0.38 μg/mL (0.38-0.41), P < 0.001]. The area under the receiver operating characteristics curve for identifying an elevated PMN count was 0.977 (95%CI: 0.933 to 0.995) for ELISA and 0.982 (95%CI: 0.942 to 0.997) for POC (P = 0.246 vs ELISA). Using the optimal cut-off value for ELISA (0.63 μg/mL), ascitic calprotectin had 94.8% sensitivity, 89.2% specificity, positive and negative likelihood ratios of 8.76 and 0.06 respectively, positive and negative predictive values of 60.0% and 99.0% respectively, and 90.0% overall accuracy. Using the optimal cut-off value for POC (0.51 μg/mL), the respective values were 100.0%, 84.7%, 6.53, 0.00, 52.8%, 100% and 87.7%. Correlation between ELISA and POC was excellent (r = 0.873, P < 0.001). The mean ± SD of the difference was -0.11 ± 0.48 μg/mL with limits of agreement of + 0.8 μg/mL (95%CI: 0.69 to 0.98) and -1.1 μg/mL (95%CI: -1.19 to -0.91). CONCLUSION: Ascitic calprotectin reliably predicts PMN count > 250/μL, which may prove useful in the diagnosis of SBP, especially with a readily available bedside testing device. | Emanuel Burri Felix Schulte Jürgen Muser Rémy Meier Christoph Beglinger | 2013 | World Journal of Gastroenterology2013,19,13: | 10 |

| 19 | Preserved liver regeneration capacity after partial hepatectomy in rats with non-alcoholic steatohepatitis显示文摘AIM To evaluate the liver regeneration capacity(LRC) after partial hepatectomy(PH) in experimental non-alcoholic steatohepatitis(NASH).METHODS Fifty-four female rats were fed a high-fat, high-cholesterol diet(HFCD, 65% fat, 1% cholesterol) or standard diet(STD) for 16 wk. A 70% PH was performed and the animals were euthanised before PH or 2 or 5 d postPH. LRC was evaluated using: The total number of Ki-67 positive hepatocytes in the caudate lobe, N(Ki-67, lobe) evaluated in a stereology-based design, the regenerated protein ratio(RPR), prothrombin-proconvertin ratio(PP), and m RNA expression of genes related to regeneration.RESULTS The HFCD NASH model showed significant steatosis with ballooning and inflammation, while no fibrosis was present. Mortality was similar in HFCD and STD animals following PH. HFCD groups were compared to respective STD groups and HFCD animals had a significantly elevated alanine transaminase at baseline(P < 0.001), as well as a significantly elevated bilirubin at day 2 after PH(P < 0.05). HFCD animals had a higher N(Ki-67, lobe) at baseline,(P < 0.0001), day 2 after PH(P = 0.06) and day 5 after PH(P < 0.025). We found no significant difference in RPR or PP neither 2 or 5 d post-PH. Expression of liver regeneration genes(e.g., hepatic growth factor) was higher at both day 2 and 5 post-PH in HFCD groups(P < 0.05).CONCLUSION NASH rats had a preserved LRC after hepatectomy when compared to STD rats. The methods and models of NASH are essential in understanding and evaluating LRC. | David Haldrup Sara Heeboll Karen Louise Thomsen Kasper Jarlhelt Andersen Michelle Meier Frank Viborg Mortensen Jens Randel Nyengaard Stephen Hamilton-Dutoit Henning Gronbaek | 2018 | World Journal of Hepatology2018,10,1: | 3 |
