| 1 | Beneficial mechanisms of aerobic exercise on hepatic lipid metabolism in non-alcoholic fatty liver disease显示文摘BACKGROUND:Non-alcoholic fatty liver disease(NAFLD)refers to any fatty liver disease that is not due to excessive use of alcohol.NAFLD probably results from abnormal hepatic lipid metabolism and insulin resistance.Aerobic exercise is shown to improve NAFLD.This review aimed to evaluate the molecular mechanisms involved in the beneficial effects of aerobic exercise on NAFLD.DATA SOURCE:We searched articles in English on the role of aerobic exercise in NAFLD therapy in Pub Med. | Rui Guo Emily C Liong Kwok Fai So Man-Lung Fung George L Tipoe | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，2： | 16 |
| 2 | Acute upper gastrointestinal bleeding in octοgenarians:Clinical outcome and factors related to mortality显示文摘AIM: To evaluate the aetiology, clinical outcome and factors related to mortality of acute upper gastrointestinal bleeding (AUGIB) in octogenarians. METHODS: We reviewed the records of all patients over 65 years old who were hospitalised with AUGIB in two hospitals from January 2006 to December of 2006. Patients were divided into two groups: Group A (65-80 years old) and Group B (> 80 years old). RESULTS: Four hundred and sixteen patients over 65 years of age were hospitalized because of AUGIB. Group A included 269 patients and Group B 147 patients. Co-morbidity was more common in octogenarians (P = 0.04). The main cause of bleeding was peptic ulcer in both groups. Rebleeding and emergency surgery were uncommon in octogenarians and not different from those in younger patients. In-hospital complications were more common in octogenarians (P = 0.05) and more patients died in the group of octogenarians compared to the younger age group (P = 0.02). Inability to perform endoscopic examination (P = 0.002), presence of high risk for rebleeding stigmata (P = 0.004), urea on admission (P = 0.036), rebleeding (P = 0.004) and presenceof severe co-morbidity (P < 0.0001) were related to mortality. In multivariate analysis, only the presence of severe co-morbidity was independently related to mortality (P = 0.032). CONCLUSION: While rebleeding and emergency surgery rates are relatively low in octogenarians with AUGIB, the presence of severe co-morbidity is the main factor of adverse outcome. | George J Theocharis Vassiliki Arvaniti Stelios F Assimakopoulos Konstantinos C Thomopoulos Vassilis Xourgias Irini Mylonakou Vassiliki N Nikolopoulou | 2008 | World Journal of Gastroenterology2008，14，25： | 15 |
| 3 | Therapeutic approaches to non-alcoholic fatty liver disease: past achievements and future challenges显示文摘BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver injury and mortality in Western countries and China. However, as to date, there is no direct and effective therapy for this disease. The aim of this review is to analyze the key progress and challenges of main current therapeutic approaches in NAFLD. DATA SOURCE: We carried out a PubMed search of English-language articles relevant to NAFLD therapy. RESULTS: There are two major therapeutic strategies for NAFLD treatment: (1) lifestyle interventions (including weight reduction, dietary modification and physical exercise) and (2) pharmaceutical therapies. Lifestyle interventions, particularly chronic and moderate intensity exercise, are the most effective and recognized clinical therapies for NAFLD. For pharmaceutical therapies, although their effects and mechanisms have been extensively investigated in laboratory studies, they still need further tests and investigations in clinical human trials. CONCLUSION: Future advancement of NAFLD therapy should focus on the mechanistic studies on cell based and animal models and human clinical trials of exercise, as well as the combination of lifestyle intervention and pharmaceutical therapy specifically targeting main signaling pathways related to lipid metabolism, oxidative stress and inflammation. | Jia Xiao Rui Guo Man Lung Fung Emily C Liong George L Tipoe | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，2： | 14 |
| 4 | Comparative clinical study of ultrasound-guided A1 pulley release vs open surgical intervention in the treatment of trigger finger显示文摘AIM To investigate the effectiveness of ultrasound-guided release of the first annular pulley and compare results with the conventional open operative technique.METHODS In this prospective randomized, single-center, clinical study, 32 patients with trigger finger or trigger thumb, grade Ⅱ-Ⅳ according to Green classification system, were recruited. Two groups were formed; Group A(16 patients) was treated with an ultrasound-guided percutaneous release of the affected A1 pulley under local anesthesia. Group B(16 patients) underwent an open surgical release of the A1 pul ey, through a 10-15 mm incision. Patients were assessed pre- and postoperatively(follow-up:2,4 and 12 wk) by physicians blinded to the procedures. Treatment of triggering(primary variable of interest) was expressed as the 'success rate' per digit. The time for taking postoperative pain killers, range of motion recovery, QuickD ASH test scores(Greek version), return to normal activities(including work), complications and cosmetic results were assessed.RESULTS The success rate in group A was 93.75%(15/16) and in group B 100%(16/16). Mean times in group A patients were 3.5 d for taking pain killers, 4.1 d for returning to normal activities, and 7.2 and 3.9 d for complete extension and flexion recovery, respectively. Mean Quick DASH scores in group A were 45.5 preoperatively and, 7.5, 0.5 and 0 after 2, 4, and 12 wk postoperatively. Mean times in group B patients were 2.9 d for taking pain killers, 17.8 d for returning to normal activities, and 5.6 and 3 d for complete extension and flexion recovery. Mean QuickD ASH scores in group B were 43.2 preoperatively and, 8.2, 1.3 and 0 after 2, 4, and 12 wk postoperatively. The cosmetic results found excellent or good in 87.5%(14/16) of group A patients, while in 56.25%(9/16) of group B patients were evaluated as fair or poor.CONCLUSION Treatment of the trigger finger using ultrasonography resulted in fewer absence of work days, and better cosmetic results, in comparison with the open surgery technique. It is a promising method that represents excellent results without major complications, so that it could be possibly be established as a first-line treatment in the trigger finger's disease. | Vasileios S Nikolaou Michael-Alexander Malahias Maria-Kyriaki Kaseta Ioannis Sourlas George C Babis | 2017 | World Journal of Orthopedics2017，8，2： | 14 |
| 5 | miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium. | Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey | 2011 | World Journal of Gastroenterology2011，17，8： | 13 |
| 6 | Duodenal adenocarcinoma: Advances in diagnosis and surgical management显示文摘Duodenal adenocarcinoma is a rare but aggressive malignancy. Given its rarity, previous studies have traditionally combined duodenal adenocarcinoma(DA) with either other periampullary cancers or small bowel adenocarcinomas, limiting the available data to guide treatment decisions. Nevertheless, management primarily involves complete surgical resection when technically feasible. Surgery may require pancreaticoduodenectomy or segmental duodenal resection; either are acceptable options as long as negative margins are achievable and an adequate lymphadenectomy can be performed. Adjuvant chemotherapy and radiation are important components of multi-modality treatment for patients at high risk of recurrence. Further research would benefit from multiinstitutional trials that do not combine DA with other periampullary or small bowel malignancies. The purpose of this article is to perform a comprehensive review of DA with special focus on the surgical management and principles. | Jordan M Cloyd Elizabeth George Brendan C Visser | 2016 | World Journal of Gastrointestinal Surgery2016，8，3： | 13 |
| 7 | Traveling wave effect on the seismic response of a steel arch bridge subjected to near fault ground motions显示文摘In the 1990s, several major earthquakes occurred throughout the world, with a common observation that near fault ground motion (NFGM) characteristics had a distinct impact on causing damage to civil engineering structures that could not be predicted by using far field ground motions. Since then, seismic responses of structures under NFGMs have been extensively examined, with most of the studies focusing on structures with relatively short fundamental periods, where the traveling wave effect does not need to be considered. However, for long span bridges, especially arch bridges, the traveling wave (only time delay considered) effect may be very distinct and is therefore important. In this paper, the results from a case study on the seismic response of a steel arch bridge under selected NFGMs is presented by considering the traveling wave effect with variable apparent velocities. The effects of fling step and long period pulses of NFGMs on the seismic responses of the arch bridge are also discussed. | 徐艳 George C Lee | 2007 | Earthquake Engineering and Engineering Vibration2007，6，3： | 11 |
| 8 | Acute upper gastrointestinal bleeding in operated stomach: Outcome of 105 cases显示文摘AIM: To compare the causes and clinical outcome of patients with acute upper gastrointestinal bleeding (AUGB) and a history of gastric surgery to those with AUGB but without a history of gastric surgery in the past.METHODS: The causes and clinical outcome were compared between 105 patients with AUGB and a history of gastric surgery, and 608 patients with AUGB but without a history of gastric surgery.RESULTS: Patients who underwent gastric surgery in the past were older (mean age: 68.1±11.7 years vs 62.8±17.8 years, P= 0.001), and the most common cause of bleeding was marginal ulcer in 63 patients (60%). No identifiable source of bleeding could be found in 22 patients (20.9%) compared to 42/608 (6.9%) in patients without a history of gastric surgery (P = 0.003). Endoscopic hemostasis was permanently successful in 26 out of 35 patients (74.3%) with peptic ulcers and active bleeding or non-bleeding visible vessel. Nine patients (8.6%) were operated due to continuing or recurrent bleeding,compared to 23/608 (3.8%) in the group of patients without gastric surgery in the past (P= 0.028). Especially in peptic ulcer bleeding patients, emergency surgery was more common in the group of patients with gastric surgery in the past [9/73 (12.3%) vs 19/360 (5.3%), P = 0.025].Moreover surgically treated patients in the past required more blood transfusion (3.3±4.0 vs 1.5±1.7, P = 0.0001) and longer hospitalization time (8.6±4.0 vs 6.9±4.9 d,P = 0.001) than patients without a history of gastric surgery. Mortality was not different between the two groups [4/105 (3.8%) vs 19/608 (3.1%)].CONCLUSION: Upper gastrointestinal bleeding seems to be more severe in surgically treated patients than in non-operated patients. | Vassiliki N Nikolopoulou Konstantinos C Thomopoulos George I Theocharis Vassiliki A Arvaniti Constantine E Vagianos | 2005 | World Journal of Gastroenterology2005，11，29： | 9 |
| 9 | Common controversies in total knee replacement surgery: Current evidence显示文摘Total knee replacement(TKR) is a widely used operation that has radically improved the quality of life of millions of people during the last few decades. However, some technical details, concerning the surgical procedure and the rehabilitation following total knee arthroplasty, are still a matter of a strong debate. In this review of the literature, we have included the best evidence available of the last decade, in an effort to shed light on some of the most controversial subjects related to TKR surgery. Posterior-stabilized or cruciate-retaining prosthesis? To use a tourniquet during operation or not? Do patients need continuous passive motion for their post-surgery rehabilitation? To resurface patella or not? These are some of the most controversial topics that until now have been persistent dilemmas for the orthopedic surgeon. Results of this systematic review of the literature are highly controversial. These conflicting results are an indication that larger and more well conducted high quality trials are needed in order to gain more secure answers. At the same time, it is becoming apparent that a meticulous operative technique, respecting the soft tissue envelope and knowing the principles of alignment and soft tissue balancing, aresome of the parameters that might contribute more to achieving the optimal results for the patients. | Vasileios S Nikolaou Dimitrios Chytas George C Babis | 2014 | World Journal of Orthopedics2014，5，4： | 9 |
| 10 | Alterations in the function of circulating mononuclear cells derived from patients with Crohn’s disease treated with mastic显示文摘AIM: To assess the effects of mastic administration on cytokine production of circulating mononuclear cells of patients with active Crohn's disease (CD). METHODS: The study was conducted in patients with established mildly to moderately active CD, attending the outpatient clinics of the hospital, and in healthy controls. Recruited to a 4 wk treatment with mastic caps (6 caps/d, 0.37 g/cap) were 10 patients and 8 controls, all of who successfully completed the protocol. Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemotactic protein-1 (MCP-1), macrophage migration inhibitory factor (MIF) and intracellular antioxidant glutathione (GSH) were evaluated in peripheral blood mononuclear cells (PBMC) before and after treatment. RESULTS: Treating CD patients with mastic resulted in the reduction of TNF-α secretion (2.1 ± 0.9 ng/mL vs 0.5 ± 0.4 ng/mL, P = 0.028). MIF release was signif icantly increased (1.2 ± 0.4 ng/mL vs 2.5 ± 0.7 ng/mL, P = 0.026) meaning that random migration and chemotaxis of monocytes/macrophages was inhibited. No signifi cant changes were observed in IL-6, MCP-1 and GSH concentrations. CONCLUSION: This study shows that mastic acts as an immunomodulator on PBMC, acting as a TNF-α inhibitor and a MIF stimulator. Although further double-blind, placebo-controlled studies in a large number of patients is required to clarify the role of this natural product, this f inding provides strong evidence that mastic might be an important regulator of immunity in CD. | Andriana C Kaliora Maria G Stathopoulou John K Triantaf illidis George VZ Dedoussis Nikolaos K Andrikopoulos | 2007 | World Journal of Gastroenterology2007，13，45： | 8 |

| 12 | Chios mastic treatment of patients with active Crohn's disease显示文摘AIM: To evaluate the effectiveness of mastic administra-tion on the clinical course and plasma inflammatory me-diators of patients with active Crohn’s disease (CD).METHODS: This pilot study was conducted in patients with established mild to moderately active CD, attend-ing the outpatient clinics of the hospital, and in healthy controls. Ten patients and 8 controls were recruited for a 4-wk treatment with mastic caps (6 caps/d, 0.37 g/cap). All patients successfully completed the protocol. CD Ac-tivity Index (CDAI), Nutritional Risk Index (NRI), C-re-active protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemotactic protein-1 (MCP-1), and total antioxidant potential (TAP) were evaluated in the plasma at baseline and at the end of the treatment period. Results were expressed as mean values ± SE and P < 0.05 was considered to indicate statistical significance.RESULTS: Patients exhibited significant reduction of CDAI (222.9 ± 18.7 vs 136.3 ± 12.3, P = 0.05) as com-pared to pretreament values. Plasma IL-6 was signifi-cantly decreased (21.2 ± 9.3 pg/mL vs 7.2 ± 2.8 pg/ mL, P = 0.027), and so did CRP (40.3 ± 13.1 mg/mL vs 19.7 ± 5.5, P = 0.028). TAP was significantly increased (0.15 ± 0.09 vs 0.57 ± 0.15 mmol/L uric acid, P = 0.036). No patient or control exhibited any kind of side effects. CONCLUSION: The results suggest that mastic signifi-cantly decreased the activity index and the plasma levels of IL-6 and CRP in patients with mildly to moderately ac-tive CD. Further double-blind, placebo-controlled studies in a larger number of patients are required to clarify the role of this natural product in the treatment of patients with CD. | Andriana C Kaliora Maria G Stathopoulou John K Triantafillidis George VZ Dedoussis Nikolaos K Andrikopoulos | 2007 | World Journal of Gastroenterology2007，13，5： | 7 |

| 14 | It is safe to use transdermal glyceryl trinitrate to lower blood pressure in patients with acute ischaemic stroke with carotid stenosis显示文摘Background There is concern that blood pressure(BP)lowering in acute stroke may compromise cerebral perfusion and worsen outcome in the presence of carotid stenosis.We assessed the effect of glyceryl trinitrate(GTN)in patients with carotid stenosis using data from the Efficacy of Nitric Oxide in Stroke(ENOS)Trial.Methods ENOS randomised 4011 patients with acute stroke and raised systolic BP(140-220 mm Hg)to transdermal GTN or no GTN within 48 hours of onset.Those on prestroke antihypertensives were also randomised to stop or continue their medication for 7 days.The primary outcome was the modified Rankin Scale(mRS)at day 90.Ipsilateral carotid stenosis was split:<30%;30-<50%;50-<70%;≥70%.Data are ORs with 95%CIs adjusted for baseline prognostic factors.results 2023(60.5%)ischaemic stroke participants had carotid imaging.As compared with<30%,≥70%ipsilateral stenosis was associated with an unfavourable shift in mRS(worse outcome)at 90 days(OR 1.88,95%CI 1.44 to 2.44,p<0.001).Those with≥70%stenosis who received GTN versus no GTN had a favourable shift in mRS(OR 0.56,95%CI 0.34 to 0.93,p=0.024).In those with 50-<70%stenosis,continuing versus stopping prestroke antihypertensives was associated with worse disability,mood,quality of life and cognition at 90 days.Clinical outcomes did not differ across bilateral stenosis groups.Conclusions Following ischaemic stroke,severe ipsilateral carotid stenosis is associated with worse functional outcome at 90 days.GTN appears safe in ipsilateral or bilateral carotid stenosis,and might improve outcome in severe ipsilateral carotid stenosis. | Jason P Appleton Lisa J Woodhouse Andrew Belcher Daniel Bereczki Eivind Berge Valeria Caso Hui Meng Chang Hanne K Christensen Ronan Collins John Gommans Ann C Laska George Ntaios Serefnur Ozturk Gillian M Sare Szabolcs Szatmari Yongjun Wang Joanna M Wardlaw Nikola Sprigg Philip M Bath for the ENOS investigators | 2019 | Stroke & Vascular Neurology2019，4，1： | 6 |
| 15 | Tetramethylpyrazine在视网膜色素上皮细胞变性及脉络膜血流和RPE细胞氧化应激中的作用(英文)显示文摘目的:研究1%Tetramethylpyrazine(TMP)在视网膜色素上皮细胞(RPE)变性,脉络膜血流和RPE细胞氧化应激中的作用。方法:在碘酸钠诱导的大鼠RPE变性研究中,1%TMP滴眼液预先处理1wk,3次/d,1wk后予碘酸钠舌下静脉注射,在2wk和4wk末,视网膜电图(ERG)测量c波。色素微球体技术分析高眼压状态下TMP对脉络膜血流的影响。Methylthiazoltetrazolium(MTT)分析TMP在各种氧化应激中对RPE的保护作用。结果:碘酸钠注射后2wk,碘酸钠组ERG的c波下降至对照组的36%(P<0.01)。4wk后,碘酸钠组下降至对照组的46%(P<0.01),而1%TMP+碘酸钠组下降至对照组的77%(P<0.01)。与碘酸钠组比较,1%TMP+碘酸钠组控制了67%的c波下降(P<0.05)。在脉络膜血流的测量中,30,60,和120min的结果显示,TMP显著增加脉络膜血流。在氧化应激部分,不同浓度的TMP在各种氧化应激损伤中,对RPE都有各种程度的保护作用。结论:浓度为1%Tetramethylpyrazine可以显著保护碘酸钠和氧化应激诱导的RPE变性,增加脉络膜血流,并可能在AMD的治疗中发挥作用。 | 沈轶 庄沛 林宝琴 张婉玉 George C Y Chiou | 2010 | 国际眼科杂志2010，10，10： | 6 |
| 16 | Transanal polypectomy using single incision laparoscopic instruments显示文摘Transanal excision of rectal polyps with laparoscopic instrumentation and a single incision laparoscopic port is a novel technique that uses technology originally developed for abdominal procedures from the natural orifice of the rectum. Transanal endoscopic microsurgery (TEM) is a well established surgical approach for certain benign or early malignant lesions of the rectum, under specific indications. Our technique is a hybrid technique of transanal surgery, a reasonable method for polyp resection without the need of the sophisticated and expensive instrumentation of TEM which can be applied whenever endoscopic or conventional transanal surgical removal is not feasible. | Dimitrios Dardamanis Dimitrios Theodorou George Theodoropoulos Andreas Larentzakis Maria Natoudi Georgia Doulami Christina Zoumpouli Haridimos Markogiannakis Stylianos Katsaragakis George C Zografos | 2011 | World Journal of Gastrointestinal Surgery2011，3，4： | 6 |
| 17 | Acute upper gastrointestinal bleeding in patients on long-term oral anticoagulation therapy: Endoscopic findings, clinical management and outcome显示文摘AIM: Acute gastrointestinal bleeding is a severe complication in patients receiving long-term oral anticoagulant therapy.The purpose of this study was to describe the causes and clinical outcome of these patients.METHODS: From January 1999 to October 2003, 111patients with acute upper gastrointestinal bleeding (AUGIB)were hospitalized while on oral anticoagulants. The causes and clinical outcome of these patients were compared with those of 604 patients hospitalized during 2000-2001with AUGIB who were not taking warfarin.RESULTS: The most common cause of bleeding was peptic ulcer in 51 patients (45%) receiving anticoagulants compared to 359/604 (59.4%) patients not receiving warfarin (P<0.05). No identifiable source of bleeding could be found in 33 patients (29.7%) compared to 31/604(5.1%) patients not receiving anticoagulants (P= 0.0001).The majority of patients with concurrent use of non-steroidal anti-inflammatory drugs (NSATDs) (26/35, 74.3%) had a peptic ulcer as a cause of bleeding while 32/76 (40.8%)patients not taking a great dose of NSATDs had a negative upper and lower gastrointestinal endoscopy. Endoscopic hemostasis was applied and no complication was reported.Six patients (5.4%) were operated due to continuing or recurrent hemorrhage, compared to 23/604 (3.8%) patients not receiving anticoagulants. Four patients died, the overall mortality was 3.6% in patients with AUGIB due to anticoagulants, which was not different from that in patients not receiving anticoagulant therapy.CONCLUSION: Patients with AUGIB while on long-term anticoagulant therapy had a clinical outcome, which is not different from that of patients not taking anticoagulants.Early endoscopy is important for the management of these patients and endoscopic hemostasis can be safely applied. | Konstantinos C Thomopoulos Konstantinos P Mimidis George J Theocharis Anthie G Gatopoulou Georgios N Kartalis Vassiliki N Nikolopoulou | 2005 | World Journal of Gastroenterology2005，11，9： | 5 |
| 18 | Are acute exacerbations of chronic inflammatory appendicitis triggered by coprostasis and/or coproliths?显示文摘AIM: To examine the role of coprostasis and coproliths in recurrent appendicitis. METHODS: We evaluated four hundred and twenty seven consecutive pathology reports of all appende- ctomy specimens from January 2003 to December 2004. Findings were categorised as showing acute appen- dicitis, acute recurrent appendicitis, subacute recurrent appendicitis, chronic appendicitis, or appendices without inflammation. All patients had presented with acute right lower quadrant pain. In 94 instances, there was a history of recurrent similar episodes in the past. RESULTS: Of the 427 histology reports, 294 were inter- preted as showing acute appendicitis, 56 acute recurrent appendicitis, 34 subacute recurrent appen-dicitis, 28 chronic appendicitis, and 15 non-inflamed appendices. Coprostasis was observed in 58 patients (13.58%) and the presence of coprolith in 6 (1.4%). Coprostasis, and age, were among the predictors in the final model. CONCLUSION: Coprostasis but not coproliths seems to be a contributing factor to acute exacerbations of chronic inflammatory appendicitis. | George Sgourakis Georgios C Sotiropoulos Ernesto P Molmenti Charis Eibl Stylianous Bonticous Jurgen Moege Christoph Berchtold | 2008 | World Journal of Gastroenterology2008，14，20： | 5 |
