| 1 | Helicobacter pylori and colorectal neoplasia:Is there acausal link?显示文摘Ever since Helicobacter pylori(H. pylori) was recognized as an infectious cause of gastric cancer, there has been increasing interest in examining its potential role in colorectal carcinogenesis. Data from casecontrol and cross-sectional studies, mostly relying on hospital-based samples, and several meta-analyses have shown a positive statistical relationship between H. pylori infection and colorectal neoplasia. However, the possibility exists that the results have been influenced by bias, including the improper selection of patients and disparities with respect to potential confounders. While the evidence falls short of a definitive causal link, it appears that infection with H. pylori /H. pylori-related gastritis is associated with an increased, although modest, risk of colorectal adenoma and cancer. The pathogenic mechanisms responsible for this association remain uncertain. H. pylori has been detected in colorectal malignant tissues; however, the possibility that H. pylori is a direct activator of colonic carcinogenesis remains purely hypothetical. On the other hand, experimental data have indicated a series of potential oncogenic interactions between these bacteria and colorectal mucosa, including induction and perpetuation of inflammatory responses, alteration of gut microflora and release of toxins and/or hormonal mediators, such as gastrin, which may contribute to tumor formation. | Vasilios Papastergiou Stylianos Karatapanis Sotirios D Georgopoulos | 2016 | World Journal of Gastroenterology2016，22，2： | 22 |
| 2 | Treatment of Helicobacter pylori infection:Meeting the challenge of antimicrobial resistance显示文摘Treatment of Helicobacter pylori(H.pylori)infection is paramount for the management of prevalent gastrointestinal disorders including peptic ulcer disease and gastric cancer.Due to the wide increase in prevalence of H.pylori resistance to antibiotics,clarithromycin-based triple therapies are not any more suitable for unconditional empiric use,and should not be recommended,unless local resistance to this antibiotic is low(<20%).Alternative strategies have been proposed to overcome the issue of increasing clarithromycin resistance,and some of them are already implemented in clinical practice.These comprise:(1)adoption of novel,more effective,empirical treatments:bismuth quadruple,sequential,non-bismuth quadruple(concomitant),dual-concomitant(hybrid),and levofloxacin-based regimens,the latter mainly designated as second-line/rescue options;(2)perspectives for a susceptibility-guided(tailored)therapeutic approach based on culture-free molecular testing methods;and(3)adjunct use of probiotics to improve eradication rates.The present article is aimed to provide a comprehensive overview of current and emerging strategies in the treatment of H.pylori infection,focusing on the challenge of antimicrobial resistance. | Vasilios Papastergiou Sotirios D Georgopoulos Stylianos Karatapanis | 2014 | World Journal of Gastroenterology2014，20，29： | 18 |
| 3 | Prediction of atrial fibrillation development and progression:current perspectives显示文摘Atrial fibrillation(AF) is the most common arrhythmia in clinical practice. Several conventional and novel predictors of AF development and progression(from paroxysmal to persistent and permanent types) have been reported. The most important predictor of AF progression is possibly the arrhythmia itself. The electrical, mechanical and structural remodeling determines the perpetuation of AF and the progression from paroxysmal to persistent and permanent forms. Common clinical scores such as the hypertension, age ≥ 75 years, transient ischemic attack or stroke, chronic obstructive pulmonary disease, and heart failure and the congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke/transient ischemic attack, vascular disease, age 65-74 years, sex category scores as well as biomarkers related to inflammation may also add important information on this topic. There is now increasing evidence that even in patients with so-called lone or idiopathic AF, the arrhythmia is the manifestation of a structural atrial disease which has recently been defined and described as fibrotic atrial cardiomyopathy. Fibrosis results from a broad range of factors related to AF inducing pathologies such as cell stretch, neurohumoral activation, and oxidative stress. The extent of fibrosis as detected either by late gadolinium enhancement-magnetic resonance imaging or electroanatomic voltage mapping may guide the therapeutic approach based on the arrhythmia substrate. The knowledge of these risk factors may not only delay arrhythmia progression, but also reduce the arrhythmia burden in patients with first detected AF. The present review highlights on the conventional and novel risk factors of development and progression of AF. | Konstantinos Vlachos Konstantinos P Letsas Panagiotis Korantzopoulos Tong Liu Stamatis Georgopoulos Athanasios Bakalakos Nikolaos Karamichalakis Sotirios Xydonas Michael Efremidis Antonios Sideris | 2016 | World Journal of Cardiology2016，8，3： | 16 |
| 4 | Treatment of Helicobacter pylori infection: Past, present and future显示文摘Helicobacter pylori(H. pylori) is a major human patho-gen associated with significant morbidity and mortal-ity. However, after decades of efforts, treatment of H. pylori remains a challenge for physicians, as there is no universally effective regimen. Due to the rising prevalence of antimicrobial resistance, mainly to clar-ithromycin, efficacy of standard triple therapies has declined to unacceptably low levels in most parts of the world. Novel regimens, specifically experimented to improve the therapeutic outcome against antibiotic-resistant H. pylori strains, are now recommended as first-line empirical treatment options providing high ef-ficacy(reportedly > 90% in intention to treat analysis) even in high clarithromycin resistance settings. These include the bismuth quadruple, concomitant, sequential and hybrid therapies. Due to the rapid development of quinolone resistance, levofloxacin-based regimens should be reserved as second-line/rescue options. Adjunct use of probiotics has been proposed in order to boost eradication rates and decrease occurrence of treatment-related side effects. Molecular testing meth-ods are currently available for the characterization of H. pylori therapeutic susceptibility, including genotypic detection of macrolide resistance and evaluation of the cytochrome P450 2C19 status known to affect the me-tabolism of proton pump inhibitors. In the future, use of these techniques may allow for culture-free, non-invasive tailoring of therapy for H. pylori infection. | Vasilios Papastergiou Sotirios D Georgopoulos Stylianos Karatapanis | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，4： | 11 |

| 7 | Inferior mesenteric arteriovenous fistula: Case report and world-literature review显示文摘Arteriovenous fistulas between the inferior mesenteric artery and vein are rare, with only 26 primary and secondary cases described in the literature. Secondary fistulas occur following operations of the left hemicolon and manifest as abdominal pain, abdominal mass, gastrointestinal bleeding, colonic ischemia and portal hypertension. Symptom intensities are flow-dependent, and can range from minimal symptoms to severe heart failure due to left to right shunt. Diagnosis is usually established by radiological or intraoperative examination. Treatment options include embolization and/or surgical resection. Therapeutic decisions should be adapted to the unique characteristics of the fistula on an individual basis. A new case of a primary arteriovenous fistula is described and discussed along with a complete review of the literature. The patient in this report presented with signs and symptoms of colonic ischemia without portal hypertension. The optimal treatment for this pa-tient required a combination of embolization and surgical operation. The characteristics of these rare inferior mesenteric arteriovenous fistulas are examined and some considerations concerning diagnostic and therapeutic strategies that should be followed are presented. | Antonios Athanasiou Adamantios Michalinos reas Alexrou Sotirios Georgopoulos Evangelos Felekouras | 2014 | World Journal of Gastroenterology2014，20，25： | 5 |

| 10 | Towards SDN Based Queuing Delay Estimation显示文摘As one of Qo S(Quality of Service) metrics, delay is critical important to delay sensitive applications, such as interactive video, network game and online surgery. In this paper, we exploit SDN(Software Defined Networking) advantages to solve delay Qo S problem. Our work mainly focuses on SDN based queuing delay estimation with real traffic and end-to-end delay control. First, we propose a queuing estimation model and extended it for end-to-end delay of the whole path. It is proved to be feasible and accurate with experimental results in SDN environment. Second, in order to demonstrate the use of our proposed model, we also implement an end-to-end delay control application in SDN. It fulfills specific delay Qo S requirements by dynamically switching flows to a suitable queue based on estimation results and delay requirements. | MA Haiyan YAN Jinyao Panagiotis Georgopoulos Bernhard Plattner | 2016 | China Communications2016，13，3： | 3 |
