| 6 | Incidence of gallstone disease in Italy:Results from a multicenter,population-based Italian study (the MICOL project)显示文摘AIM:To evaluate gallstone incidence and risk factors in a large population-based study. METHODS: Gallstone incidence and risk factors, were evaluated by structured questionnaire and physical examination, respectively, in 9611 of 11 109 (86.5%) subjects who were gallstone-free at the cross-sectional study. RESULTS: Six centers throughout Italy enrolled 9611 subjects (5477 males, 4134 females, aged 30-79 years), 9517 of whom were included into analysis: 424 subjects (4.4%) had gallstones and 61 (0.6%) had been cholecystectomized yielding a cumulative incidence of 0.67% per year (0.66% in males, 0.81% in females). Increasing age, a high body mass index (BMI), a history of diabetes, peptic ulcer and angina, and low cholesterol and high triglyceride levels were identifi ed as risk factors in men while, in females, the only risk factors were increasing age and a high BMI.Increasing age and pain in the right hypocondrium in men and increasing age in females were identifi ed as predictors of gallstones. Pain in the epigastrium/ right hypocondrium was the only symptom related to gallstones; furthermore, some characteristics of pain (forcing to rest, not relieved by bowel movements) were significantly associated with gallstones. No correlation was found between gallstone characteristics and clinical manifestations, while increasing age in men and increasing age and BMI in females were predictors of pain. CONCLUSION:Increasing age and BMI represent true risk factors for gallstone disease (GD); pain in the right hypocondrium and/or epigastrium is confi rmed as the only symptom related to gallstones. | Davide Festi Ada Dormi Simona Capodicasa Tommaso Staniscia Adolfo F Attili Paola Loria Paolo Pazzi Giuseppe Mazzella Claudia Sama Enrico Roda Antonio Colecchia | 2008 | World Journal of Gastroenterology2008,14,34: | 23 |
| 7 | Correlation between expression of cyclooxygenase-2 and the presence of inflammatory cells in human primary hepatocellular carcinoma: Possible role in tumor promotion and angiogenesis显示文摘AIM: To investigate the association of cyclooxygenase-2(COX-2) expression with angiogenesis and the number and type of inflammatory cells (macrophages/Kupffer cells;mast cells) within primary hepatocellular carcinoma (HCC)tissues and adjacent non-tumorous (MT) tissues.METHODS: Immunohistochemistry for COX-2, CD34,CD68 and mast cell tryptase (MCT) was performed on 14 well-characterized series of liver-cirrhosis-associated HCC patients. COX-2 expression and the number of inflammatory cells in tumor lesions and surrounding liver tissues of each specimen were compared. Moreover,COX-2, CD34 staining and the number of inflammatory cells in areas with different histological degrees within each tumor sample were comparatively analyzed.RESULTS: The percentage of COX-2 positive cells was significantly higher in NT tissues than in tumors. COX-2 expression was higher in well-differentiated HCC than in poorly-differentiated tissues. Few mast cells were observed within the tumor mass, whereas a higher number was observed in the surrounding tissue, especially in peri-portal spaces of NT tissues. Abundant macrophages/Kupffer cells were observed in NT tissues, whereas the number of cells was significantly lower in the tumor mass.However, a higher cell number was observed in the well-differentiated tumor and progressively decreased in relation to the differentiation grade. Within the tumor, a positive correlation was found between COX-2 expression and the number of macrophages/Kupffer cells and mast cells. Moreover, there was a positive correlation between CD34 and COX-2 expression in tumor tissues. Comparison between well- and poorly-differentiated HCC showed that the number of CD34-positive cells decreased with dedifferentiation. However, COX-2 was the only independent variable showing a positive correlation with CD34 in a multivariate analysis.CONCLUSION: The presence of inflammatory cells and COX-2 expression in liver tumor suggests a possible relationship with tumor angiogenesis. COX-2 expressing cells and the number of macrophages/Kupffer cells and mast cells decrease with progression of the disease. | Melchiorre Cervello Daniela Foderà Ada Maria Florena Maurizio Soresi Claudio Tripodo Natale D'Alessandro Giuseppe Montalto | 2005 | World Journal of Gastroenterology2005,11,30: | 21 |
| 8 | Hepatitis B virus genotype has no impact on hepatitis B e antigen seroconversion after lamivudine treatment显示文摘AIM: To investigate the association of hepatitis B virus (HBV) genotype and HBeAg seroconversion after nucleotide analogue treatment.METHODS: Chronic hepatitis B patients receiving lamivudine followed up for at least 6 months post-treatment were studied. Consecutive treatment-naive patients who were prospectively followed up in the clinic for at least 18 months were studied as controls. HBeAg seroconversion was defined as loss of HBeAg, appearance of anti-HBe and normalization of alanine aminotransferase for at least 6 months.RESULTS: Thirty-five patients on lamivudine and 96 control patients followed up for 39 (18-49) months were studied.Lamivudine was given for 12 (10-18) months, and patients were followed up for 15 (6-34) months after drug cessation.Genotype B and C HBV were found in 43 and 88 patients and HBeAg seroconversion occurred in 12 (28 %) and 16(18 %) patients, respectively (P=0.30). There was no difference in HBeAg seroconversion between patients infected by genotype B and C HBV in the control (35 % vs 21%, P=0.25) and lamivudine-treated (14 % vs 10 %,P=1.00) groups.CONCLUSION: HBeAg seroconversion after treatment by lamivudine was not influenced by the HBV genotype. | Henry Lik-Yuen Chan May-Ling Wong Alex Yui Hui Angel Mei-Ling Chim Ada Mei-Ling Tse Lawrence Cheung-Tsui Hung Francis Ka-Leung Chan Joseph Jao-Yiu Sung | 2003 | World Journal of Gastroenterology2003,9,12: | 21 |
| 9 | Use of albendazole sulfoxide, albendazole sulfone, and combined solutions as scolicidal agents on hydatid cysts (in vitro study)显示文摘AIM: To establish which scolicidal agents are superiorand more suitable for regular use.METHODS: Echinococcus granulosus protoscoleceswere obtained from 25 patients with liver hydatidcysts. Various concentrations of albendazole sulfone,albendazole sulfoxide, and albendazole sulfone andalbendazole sulfoxide mixed together in concentrationsof 50 μg/mL, and H2O2 in a concentration of 4%, NaCl20%, and 1.5% cetrimide-0.15% chlorhexidine (10%Savlon-Turkey) were used to determine the scolicidaleffects. Albendazole (ABZ) derivatives and otherscolicidal agents were applied to a minimum of 100scoleces for 5 and 10 min. The degree of viability wascalculated according to the number of living scolicesper fi eld from a total of 100 scolices observed underthe microscope.RESULTS: After 5 min, ABZ sulfone was 97.3%effective, ABZ sulfoxide was 98.4% effective, and thecombined solution was 98.6% effective. When sulfone,sulfoxide and the combined solutions were compared,the combined solution seemed more effective thansulfone. However, there was no difference when thecombined solution was compared with sulfoxide. After10 min, hypertonic salt water, sulfone, sulfoxide, andthe combined solution compared to other solutionslooked more effective and this was statisticallysignificant on an advanced level. When sulfone,sulfoxide, and the combined solutions were compared with each other, the combined solution appeared more effective than sulfone. When the combined solution was compared with sulfoxide, there was no difference.CONCLUSION: Despite being active, ABZ metabolites did not provide a marked advantage over 20% hypertonic saline. According to these results, we think creating a newly improved and more active preparation is necessary for hydatid cyst treatment. | Gokhan Adas Soykan Arikan Ozgur Kemik Ali Oner Nilgun Sahip Oguzhan Karatepe | 2009 | World Journal of Gastroenterology2009,15,1: | 19 |

| 16 | Prevalence of metabolic syndrome, obesity and diabetes type 2 in cryptogenic cirrhosis显示文摘AIM: To evaluate the prevalence of metabolic syndrome (MS), obesity and type 2 diabetes mellitus (T2DM) in a group of Mexican Mestizo patients with cryptogenic cirrhosis (CC) and to compare this group with patients with cirrhosis secondary to other causes (disease controls). METHODS: Patients with CC, diagnosed between January, 1990 and April, 2005, were included in a retrospective study. Patients with cirrhosis caused by chronic hepatitis C, alcohol abuse or autoimmune hepatitis (AIH) served as disease controls. RESULTS: A total of 134 patients with CC were analyzed. Disease controls consisted of 81 patients with chronic hepatitis C, 33 with alcohol abuse and 20 with AIH. The median age of patients with CC was 57 years (range, 16-87); 83 (61.9%) patients were female; 53 (39.6%) were Child A, 65 (48.5%) Child B, and 16 (11.9%) were Child C cirrhosis. The prevalence of MS (29.1% vs 6%; P < 0.001), obesity (16.4% vs 8.2%; P = 0.04) and T2DM (40% vs 22.4%; P = 0.013) was higher in CC patients than in disease controls. There were no differences in sex, age or liver function tests between the two groups. CONCLUSION: The prevalence of MS, obesityand T2DM were higher in patients with CC than in patients with cirrhosis secondary to others causes. Our findings support the hypothesis that non-alcoholic steatohepatitis (NASH) plays an under-recognized role in CC. | Felix I Tellez-Avila Francisco Sanchez-Avila Mauricio García-Saenz-de-Sicilia Norberto C Chavez-Tapia Ada M Franco-Guzman Gustavo Lopez-Arce Eduardo Cerda-Contreras Misael Uribe | 2008 | World Journal of Gastroenterology2008,14,30: | 6 |
| 17 | Gene expression profiling and endothelin in acute experimental pancreatitis显示文摘AIM:To analyze gene expression profiles in an experimental pancreatitis and provide functional reversal of hypersensitivity with candidate gene endothelin-1 antagonists.METHODS:Dibutyltin dichloride(DBTC) is a chemical used as a polyvinyl carbonate stabilizer/catalyzer,biocide in agriculture,antifouling agent in paint and fabric.DBTC induces an acute pancreatitis flare through generation of reactive oxygen species.Lewis-inbred rats received a single i.v.injection with either DBTC or vehicle.Spinal cord and dorsal root ganglia(DRG) were taken at the peak of inflammation and processed for transcriptional profiling with a cDNA microarray biased for rat brain-specific genes.In a second study,groups of animals with DBTC-induced pancreatitis were treated with endothelin(ET) receptor antagonists [ET-A(BQ123) and ET-B BQ788)].Spontaneous pain related mechanical and thermal hypersensitivity were measured.Immunohistochemical analysis was performed using anti-ET-A and ET-B antibodies on sections from pancreatic tissues and DRG of the T10-12 spinal segments.RESULTS:Animals developed acute pancreatic inflammation persisting 7-10 d as confirmed by pathological studies(edema in parenchyma,loss of pancreatic architecture and islets,infiltration of inflammatory cells,neutrophil and mononuclear cells,degeneration,vacuolization and necrosis of acinar cells) and the painrelated behaviors(cutaneous secondary mechanical and thermal hypersensitivity).Gene expression profile was different in the spinal cord from animals with pancreatitis compared to the vehicle control group.Over 260 up-regulated and 60 down-regulated unique genes could be classified into 8 functional gene families:circulatory/acute phase/immunomodulatory;extracellular matrix;structural;channel/receptor/transporter;signaling transduction;transcription/translation-related;antioxidants/chaperones/heat shock;pancreatic and other enzymes.ET-1 was among the 52 candidate genes upregulated greater than 2-fold in animals with pancreatic inflammation and visceral pain-related behavior.Treatments with the ET-A(BQ123) and ET-B(BQ-788) antagonists revealed significant protection against inflammatory pain related mechanical and thermal hypersensitivity behaviors in animals with pancreatitis(P < 0.05).Open field spontaneous behavioral activity(at baseline,day 6 and 30 min after drug treatments(BQ123,BQ788) showed overall stable activity levels indicating that the drugs produced no undesirable effects on normal exploratory behaviors,except for a trend toward reduction of the active time and increase in resting time at the highest dose(300 μmol/L).Immunocytochemical localization revealed that expression of ET-A and ET-B receptors increased in DRG from animals with pancreatitis.Endothelin receptor localization was combined in dual staining with neuronal marker NeuN,and glia marker,glial fibrillary acidic protein.ET-A was expressed in the cell bodies and occasional nuclei of DRG neurons in na ve animals.However,phenotypic expression of ET-A receptor was greatly increased in neurons of all sizes in animals with pancreatitis.Similarly,ET-B receptor was localized in neurons and in the satellite glia,as well as in the Schwann cell glial myelin sheaths surrounding the axons passing through the DRG.CONCLUSION:Endothelin-receptor antagonists protect against inflammatory pain responses without interfering with normal exploratory behaviors.Candidate genes can serve as future biomarkers for diagnosis and/or targeted gene therapy. | Helieh S Oz Ying Lu Louis P Vera-Portocarrero Pei Ge Ada Silos-Santiago Karin N Westlund | 2012 | World Journal of Gastroenterology2012,18,32: | 6 |
| 18 | Effects of glutamine and curcumin on bacterial translocation in jaundiced rats显示文摘AIM: To investigate the effect of curcumin on bacterial translocation and oxidative damage in an obstructive jaundice model and compare the results to glutamine, an agent known to be effective and clinically used. METHODS: Twenty-four female Wistar-Albino rats, weighing 200-250 g, were randomly divided into three groups (8 in each group). After ligation of the common bile duct in all animals, GroupⅠ received oral normal saline, Group Ⅱ received oral glutamine and Group Ⅲ received oral curcumin for seven days. Blood samples via cardiac puncture, tissue samples (terminal ileum, liver and mesenteric lymph node) and peritoneal fluid were obtained from the animals at the time of death to investigate bacterial translocation and oxidative damage. RESULTS: We observed that both glutamine and curcumin reduced bacterial translocation in blood, hepatocellular damage, plasma cytokine levels, oxidative tissue damage and apoptosis significantly compared to the control group. Additionally, glutamine showed protective effects on ileal epithelium and reduced villus atrophy. CONCLUSION: On the basis of these findings, both curcumin and glutamine are thought to be effective in preventing or reducing bacterial translocation and oxidative damage in obstructive jaundice. | Oguzhan Karatepe Ersin Acet Muharrem Battal Gokhan Adas Ahu Kemik Merih Altiok Gulcin Kamali Safiye Koculu Atahan Catay Sedat Kamali Servet Karahan | 2010 | World Journal of Gastroenterology2010,16,34: | 5 |

| 20 | 经直肠超声引导下穿刺活检诊断前列腺癌与直肠指检和前列腺特异性抗原水平的关系:在中国人群中的情况如何?显示文摘我们分析了经直肠超声引导下穿刺活检后前列腺癌的检出率与直肠指检和前列腺特异性抗原水平的关系以及中国人群检出前列腺癌的危险因素。我们从数据库中检索了自2000年到2013年所有首次接受经直肠超声引导下前列腺穿刺活检的中国男性的数据。结合直肠指检的发现以及前列腺特异性抗原水平(〈 4, 4-10, 10.1-20,20.1-50 , 〉 50ng/ml)分析了前列腺癌的检出率。使用多因素Logistic回归研究了前列腺癌检出的潜在危险因素。共有2606中国男性人群纳入该研究。在直肠指检正常的患者中,不同前列腺特异性抗原水平(〈 4, 4-10,10.1-20, 20.1-50, 〉 50 ng/ml)患者前列腺癌的检出率分别为8.6%,13.4%,21.8%,41.7%和85.2%。在直肠指检异常的患者中,不同前列腺特异性抗原水平(〈 4, 4-10, 10.1-20, 20.1-50, 〉 50 ng/ml)患者前列腺癌的检出率分别为12.4%, 30.2%, 52.7%, 80.6%和96.4%。多因素Logistic回归分析提示:老龄、较小的前列腺体积、更多针数的穿刺活检、直肠指检异常发现、较高的PSA水平都与增大的前列腺癌检出风险相关(P 〈0.001)。与西方人群相比,中国男性人群的前列腺癌检出率较低。考虑到不同的危险因素,可以采用个体化的方式来决定是否采取经直肠超声引导下穿刺活检。 | Jeremy YC Teoh Steffi KK Yuen James HL Tsu Charles KW Wong Brian SH Ho Ada TL Ng Wai-Kit Ma Kwan-Lun Ho Ming-Kwong Yiu | 2015 | Asian Journal of Andrology2015,17,5: | 4 |
