| 1 | Colorectal cancer,screening and primary care: A mini literature review显示文摘Colorectal cancer(CRC) is a common health problem,representing the third most commonly diagnosed cancer worldwide and causing a significant burden in terms of morbidity and mortality,with annual deaths estimated at 700000. The western way of life,that is being rapidly adopted in many regions of the world,is a well discussed risk factor for CRC and could be targeted in terms of primary prevention. Furthermore,the relatively slow development of this cancer permits drastic reduction of incidence and mortality through secondary prevention. These facts underlie primary care physicians(PCPs) being assigned a key role in health strategies that enhance prevention and prompt diagnosis. Herein,we review the main topics of CRC in the current literature,in order to better understand its pathogenesis,risk and protective factors,as well as screening techniques. Furthermore,we discuss preventive and screening policies to combat CRC and the crucial role served by PCPs in their successful implementation. Relevant articles were identified through electronic searches of MEDLINE and through manual searches of reference lists. | Athanasios Hadjipetrou Dimitrios Anyfantakis Christos G Galanakis Miltiades Kastanakis Serafim Kastanakis | 2017 | World Journal of Gastroenterology2017，23，33： | 13 |
| 2 | Effect of bombesin and neurotensin on gut barrier function in partially hepatectomized rats显示文摘AIM: To investigate the effect of regulatory peptides bombesin (BBS) and neurotensin (NT) on intestinal barrier function in partially hepatectomized rats.METHODS: Ninety male Wistar rats were randomly divided into five groups: Ⅰ (n = 10): controls, Ⅱ (n =20): sham operated, Ⅲ (n = 20): partial hepatectomy 70% (PHx), Ⅳ (n = 20): PHx+BBS (30 μg/kg/d), Ⅴ (n= 20): PHx+NT (300 μg/kg/d). Groups Ⅳ and Ⅴ were treated for 8 days before PHx and 48 h post surgery.At the end of the experiment, on day 10, intestinal barrier function was assessed by measuring endotoxin concentrations in portal and aortic blood. Tissue sections of the terminal ileum were examined histologically and villus density, mucosal thickness, mitotic activity and apoptosis in crypts were assessed. In addition, ileal mucosa was analyzed for DNA and protein content and microbiological analysis was performed in cecal contents.To estimate intestinal oxidative stress, lipid peroxidation was determined on tissue homogenates from terminal ileum.RESULTS: BBS or NT administration significantly reduced portal and systemic endotoxemia observed 48 h after partial hepatectomy. In hepatectomized rats (group Ⅲ), a trend towards induction of mucosal atrophy was observed, demonstrated by the reduction of villus density, mucosal thickness, protein content and significant reduction of DNA, while these alterations were reversed by regulatory peptides administration.This trophic effect of BBS and NT was accompanied by induction of mitoses above control levels and a significant reduction of apoptosis in intestinal crypts.Intestinal lipid peroxidation was found significantly lower in PHx group and regulatory peptides exerted an antioxidant action, further decreasing this parameter of oxidative stress. The bacterial population of E. coli and aerobic Gram (+) cocci was increased in cecal content of hepatectomized rats, while this parameter was not affected by the administration of BBS or NT.CONCLUSION: Gut regulatory peptides BBS and NT improve intestinal barrier function and reduce endotoxemia in experimental partial hepatectomy. This effect is, at least in part, mediated by their trophic,antiapoptotic, mitogenic, and antioxidant effect on the intestinal epithelium. This observation might be of potential value in patients undergoing liver resection. | Stelios F Assimakopoulos Ilias H Alexandris Chrisoula D Scopa Panagiotis G Mylonas Konstantinos C Thomopoulos Christos D Georgiou Vassiliki N Nikolopoulou Constantine E Vagianos | 2005 | World Journal of Gastroenterology2005，11，43： | 8 |
| 3 | Selection criteria for liver resection in patients with hepatocellular carcinoma and chronic liver disease显示文摘Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide with an annual occurrence of one million new cases. An etiologic association between HBV infection and the development of HCC has been established with a relative risk 200-fold greater than in non-infected individuals. Hepatitis C virus is also proving an important predisposing factor for this malignancy with an incidence rate of 7% at 5 years and 14% at 10 years. The prognosis depends on tumor stage and degree of liver function, which affect the tolerance to invasive treatments. Although surgical resection is generally accepted as the treatment of choice for HCC, new treatment strategies, such as local ablative therapies, transarterial embolization and liver transplantation, have been developed nowadays. With increasing detection of small HCCs from screening programs for cirrhotic patients, it is foreseen that locoregional therapy will play an important role in the near future. | Spiros G Delis Christos Dervenis | 2008 | World Journal of Gastroenterology2008，14，22： | 7 |
| 4 | Primary pancreatic anaplastic large cell lymphoma, ALK negative: A case report显示文摘We present the fourth case of a primary pancreatic anaplastic large cell lymphoma (ALCL), ALK-. An 80-year-old man was admitted to our clinic for further investigation of a fever of unknown origin. He noted anorexia, weight loss and fatigue. His laboratory tests showed anemia and a great elevation of ESR, LDH, and β2 microglobulin. In CT and MRI scan, a soft tissue mass in the pancreas was observed. A repeated endoscopy after his admission revealed an ulcerated mass-like deformity of the duodenal bulb. Explorative laparotomy confirmed a diffuse spread of an unresectable malignant pancreatic mass extending to the adjacent organs. Duodenal and surgical biopsies identified an ALCL of T-cell lineage, ALK-. The patient died in the Intensive Care Unit due to hemodynamic instability.Our case is the first one indicating that primary pancreatic lymphoma should be suspected in a patient with pancreatic mass and elevated serum LDH and β2 microglobulin. | Christos G Savopoulos NE Tsesmeli GD Kaiafa AT Zantidis MT Bobos AI Hatzitolios ST Papavramidis IS Kostopoulos | 2005 | World Journal of Gastroenterology2005，11，39： | 3 |
| 5 | 22-gauge core vs 22-gauge aspiration needle for endoscopic ultrasound-guided sampling of abdominal masses显示文摘AIM To compare the aspiration needle(AN) and core biopsy needle(PC) in endoscopic ultrasound-guided fine needle aspiration(EUS-FNA) of abdominal masses.METHODS Consecutive patients referred for EUS-FNA were included in this prospective single-center trial. Each patient underwent a puncture of the lesion with both standard 22-gauge(G) AN(Echo Tip Ultra; Cook Medical, Bloomington, Indiana, United States) and the novel 22 G PC(Echo Tip Pro Core; Cook Medical, Bloomington, Indiana, United States) in a randomized fashion; histology was attempted in the PC group only. The main study endpoint was the overall diagnostic accuracy, including the contribution of histology to the final diagnosis. Secondary outcome measures included material adequacy, number of needle passes, and complications.RESULTS Fifty six consecutive patients(29 men; mean age 68 years) with pancreatic lesions(n = 38), lymphadenopathy(n = 13), submucosal tumors(n = 4), or others lesions(n = 1) underwent EUS-FNA using both of the needles in a randomized order. AN and PC reached similar overall results for diagnostic accuracy(AN: 88.9 vs PC: 96.1, P = 0.25), specimen adequacy(AN: 96.4% vs PC: 91.1%, P = 0.38), mean number of passes(AN: 1.5 vs PC: 1.7, P = 0.14), mean cellularity score(AN: 1.7 vs PC: 1.1, P = 0.058), and complications(none). A diagnosis on the basis of histology was achieved in the PC group in 36(64.3%) patients, and in 2 of those as the sole modality. In patients with available histology the mean cellularity score was higher for AN(AN: 1.7 vs PC: 1.0, P = 0.034); no other differences were of statistical significance.CONCLUSION Both needles achieved high overall diagnostic yields and similar performance characteristics for cytological diagnosis; histological analysis was only possible in 2/3 of cases with the new needle. | William Sterlacci Athanasios D Sioulas Lothar Veits Pervin G?nüllü Guido Schachschal Stefan Groth Mario Anders Christos K Kontos Theodoros Topalidis Andrea Hinsch Michael Vieth Thomas R?sch Ulrike W Denzer | 2016 | World Journal of Gastroenterology2016，22，39： | 2 |
| 6 | COVID-19 and liver injury: An ongoing challenge显示文摘The new coronavirus severe acute respiratory syndrome coronavirus 2(SARSCoV-2)was identified in December 2019,in Wuhan,China.The virus was rapidly spread worldwide,causing coronavirus disease 2019(COVID-19)pandemic.Although COVID-19 is presented,usually,with typical respiratory symptoms(i.e.,dyspnea,cough)and fever,extrapulmonary manifestations are also encountered.Liver injury is a common feature in patients with COVID-19 and ranges from mild and temporary elevation of liver enzymes to severe liver injury and,even,acute liver failure.The pathogenesis of liver damage is not clearly defined;multiple mechanisms contribute to liver disorder,including direct cytopathic viral effect,cytokine storm and immune-mediated hepatitis,hypoxic injury,and druginduced liver toxicity.Patients with underlying chronic liver disease(i.e.,cirrhosis,non-alcoholic fatty liver disease,alcohol-related liver disease,hepatocellular carcinoma,etc.)may have greater risk to develop both severe COVID-19 and further liver deterioration,and,as a consequence,certain issues should be considered during disease management.The aim of this review is to present the prevalence,clinical manifestation and pathophysiological mechanisms of liver injury in patients with SARS-CoV-2 infection.Moreover,we overview the association between chronic liver disease and SARS-CoV-2 infection and we briefly discuss the management of liver injury during COVID-19. | Ioanna Papagiouvanni Serafeim-Chrysovalantis Kotoulas Athanasia Pataka Dionisios G Spyratos Konstantinos Porpodis Afroditi K Boutou Georgios Papagiouvannis Ioanna Grigoriou Christos Vettas Ioannis Goulis | 2023 | World Journal of Gastroenterology2023，29，2： | 2 |
