| 1 | Expression of HER2 and bradykinin B_1 receptors in precursor lesions of gallbladder carcinoma显示文摘AIM:To determine the expression of HER2 and bradykinin B 1 receptors(B 1 R) in the two pathogenic models of gallbladder cancer:the metaplasia-dysplasia-carcinoma and the adenoma-carcinoma pathways.METHODS:Receptor proteins were visualized by immunohistochemistry on 5-μm sections of paraffin-embedded tissue.Expression of both receptors was studied in biopsy samples from 92 patients(6 males and 86 females;age ranging from 28 to 86 years,mean 56 years).High HER2 expression in specimens was additionally investigated by fluorescence in situ hybridiza-tion.Cell proliferation in each sample was assessed by using the Ki-67 proliferation marker.RESULTS:HER2 receptor protein was absent in adenomas and in normal gallbladder epithelium.On the contrary,there was intense staining for HER2 on the basolateral membrane of epithelial cells of intestinal metaplasia(22/24;91.7%) and carcinoma in situ(9/10;90%),the lesions that displayed a significantly high proliferation index.Protein up-regulation of HER2 in the epithelium with metaplasia or carcinoma in situ was not accompanied by HER2 gene amplification.A similar result was observed in invasive carcinomas(0/12).The B 1 R distribution pattern mirrored that of HER2 except that B 1 R was additionally observed in the adenomas.The B 1 R appeared either as cytoplasmic dots or labeling on the apical cell membrane of the cells composing the epithelia with intestinal metaplasia(24/24;100%) and carcinoma in situ(10/10;100%) and in the epithelial cells of adenomas.In contrast,both HER2(4/12;33%) and B 1 R(1/12;8.3%) showed a low expression in invasive gallbladder carcinomas.CONCLUSION:The up-regulation of HER2 and B1R in precursor lesions of gallbladder carcinoma suggests cross-talk between these two receptors that may be of importance in the modulation of cell proliferation in gallbladder carcinogenesis. | Cesar Toledo Carola E Matus Ximena Barraza Pamela Arroyo Pamela Ehrenfeld Carlos D Figueroa Kanti D Bhoola Maeva del Pozo Maria T Poblete | 2012 | World Journal of Gastroenterology2012,18,11: | 6 |

| 4 | Pentoxifylline 通过 TNF- 合成和 TGF-1 基因表示的下面规定改进肝新生显示文摘 AIM:To investigate the mechanism of pentoxifylline(PTX)improvement in liver regeneration.RESULTS:Rats were randomized into 4 groups:Control rats;Sham-sham-operation rats;Saline-70% hepatectomy plus saline solution;PTX-70%hepatectomy plus PTX.At 2 and 6 h after hepatectomy,aspartate aminotransferase,alanine aminotransferase,tumor necrosis factor(TNF)-α and interleukin-6(IL-6)serum and hepatic tissue levels were determined.Tumor growth factor(TGF)-β1 gene expression in liver tissue was evaluated 24 h after hepatectomy by quantitative reverse transcriptase polymerase chain reaction analysis.Proliferation was analyzed by mitotic index and proliferating cell nuclear antigen(PCNA)staining 48 h after hepatectomy.RESULTS:TNF-α and IL-6 serum levels increased at 2 and 6 h after hepatectomy.At 2 h after hepatectomy serum PTX was reduced but not hepatic levels of TNF-α and IL-6.A decrease in liver TGF-β1 gene expression and an increase in mitotic index and PCNA after hepatectomy were observed in the PTX treatment group in comparison to the saline group.CONCLUSION:PTX improves liver regeneration by a mechanism related to down regulation of TNF-α production and TGF-β1 gene expression. | Rodrigo Bronze Martino Ana Maria Mendona Coelho Márcia Saldanha Kubrusly Regina Leito Sandra Nassa Sampietre Marcel Cerqueira Cesar Machado Telesforo Bacchella Luiz Augusto Carneiro D’Albuquerque | 2012 | World Journal of Gastrointestinal Surgery2012,4,6: | 2 |
| 5 | Beneficial effects of adenosine triphosphate-sensitive K^+ channel opener on liver ischemia/reperfusion injury显示文摘AIM:To investigate the effect of diazoxide administration on liver ischemia/reperfusion injury.METHODS:Wistar male rats underwent partial liver ischemia performed by clamping the pedicle from the medium and left anterior lateral segments for 1 h under mechanical ventilation.They were divided into 3 groups:Control Group,rats submitted to liver manipulation,Saline Group,rats received saline,and Diazoxide Group,rats received intravenous injection diazoxide(3.5 mg/kg) 15 min before liver reperfusion.4 h and 24 h after reperfusion,blood was collected for determination of aspartate transaminase(AST),alanine transaminase(ALT),tumor necrosis factor(TNF-α),interleukin-6(IL-6),interleukin-10(IL-10),nitrite/nitrate,creatinine and tumor growth factor-β1(TGF-β1).Liver tissues were assembled for mitochondrial oxidation and phosphorylation,malondialdehyde(MDA) content,and histologic analysis.Pulmonary vascular permeability and myeloperoxidase(MPO) were also determined.RESULTS:Four hours after reperfusion the diazoxide group presented with significant reduction of AST(2009 ± 257 U/L vs 3523 ± 424 U/L,P = 0.005); ALT(1794 ± 295 U/L vs 3316 ± 413 U/L,P = 0.005); TNF-α(17 ± 9 pg/mL vs 152 ± 43 pg/mL,P = 0.013; IL-6(62 ± 18 pg/mL vs 281 ± 92 pg/mL); IL-10(40 ± 9 pg/mL vs 78 ± 10 pg/mL P = 0.03),and nitrite/nitrate(3.8 ± 0.9 μmol/L vs 10.2 ± 2.4 μmol/L,P = 0.025) when compared to the saline group.A significant reduction in liver mitochondrial dysfunction was observed in the diazoxide group compared to the saline group(P < 0.05).No differences in liver MDA content,serum creatinine,pulmonary vascular permeability and MPO activity were observed between groups.Twenty four hours after reperfusion the diazoxide group showed a reduction of AST(495 ± 78 U/L vs 978 ± 192 U/L,P = 0.032); ALT(335 ± 59 U/L vs 742 ± 182 U/L,P = 0.048),and TGF-β1(11 ± 1 ng/mL vs 17 ± 0.5 ng/mL,P = 0.004) serum levels when compared to the saline group.The control group did not present alterations when compared to the diazoxide and saline groups.CONCLUSION:Diazoxide maintains liver mitochondrial function,increases liver tolerance to ischemia/reperfusion injury,and reduces the systemic inflammatory response.These effects require further evaluation for using in a clinical setting. | Mateus Antunes Nogueira Ana Maria Mendona Coelho Sandra Nassa Sampietre Rosely Antunes Patzina Fabiano Pinheiro da Silva Luiz Augusto Carneiro D'Albuquerque Marcel Cerqueira Cesar Machado | 2014 | World Journal of Gastroenterology2014,20,41: | 2 |

| 20 | Persistence of high CD40 and CD40L expression after restorative proctocolectomy for ulcerative colitis显示文摘AIM: To focus on the role of CD40 and CD40L in their pathogenesis.METHODS: We analyzed by immunohistochemistry the CD40 and CD40L expression in the pouch mucosa of 28 patients who had undergone RPC for UC, in the terminal ileum of 6 patients with UC and 11 healthy subjects. We also examined by flow cytometry the expression of CD40 by B lymphocytes and monocytes in the peripheral blood of 20 pouch patients, 15 UC patients and 11 healthy controls.RESULTS: Ileal pouch mucosa leukocytes presented a significantly higher expression of CD40 and CD40L as compared to controls. This alteration correlated with pouchitis, but was also present in the healthy pouch and in the terminal ileum of UC patients. CD40 expression of peripheral B lymphocytes was significantly higher in patients with UC and pouch, respect to controls. Increased CD40 levels in blood B cells of pouch patients correlatedwith the presence of spondyloarthropathy, but not with pouchitis, or inflammatory indices.CONCLUSION: High CD40 expression in the ileal pouch mucosa could be implied in the pathogenesis of pouchitis following proctocolectomy for UC, whereas its increased levels on peripheral blood B lymphocytes are associated with the presence of extraintestinal manifestations. | Lino Polese Imerio Angriman Giuseppe De Franchis Attilio Cecchetto Giacomo C.Sturniolo Renata D'Incà Marco Scarpa Cesare Ruffolo Lorenzo Norberto Mauro Frego Davide F D'Amico | 2005 | World Journal of Gastroenterology2005,11,34: | 1 |
