| 1 | Expression of COX-2, PCNA, Ki-67 and p53 in gastrointestinal stromal tumors and its relationship with histopathological parameters显示文摘AIM: To investigate the expression of Cyclooxygenase-2 (COX-2), proliferating cell nuclear antigen (PCNA), Ki-67 and p53 in gastrointestinal stromal tumors (GISTs) and its relationship with histopathological parameters. METHODS: Twenty-five GISTs were examined by light microscopy and immunohistochemistry. c-kit, CD34, SMA, S-100 protein, COX-2, PCNA, Ki-67 and p53 were detected immunohistochemically and the relationship was evaluated among histopathologic parameters such as mitotic index (MI), tumor grade, tumor size, COX-2, PCNA, Ki-67 and p53. RESULTS: COX-2 protein expression was found in 19 of 25 (76%) of the tumors, and expression was noted in the cytoplasm of the tumor cells. p53 was significantly related to MI and tumor grade but no relationship was found between COX-2, proliferation markers and MI, tumor grade and tumor size. CONCLUSION: COX-2 is expressed in most GISTs and it may play an important role in the proliferation and progression of these tumors or a useful marker to identify GIST. Although immunohistochemical assessment of p53 can be used for distinguishing the risk groups of GISTs, tumor size and mitotic rate should be considered at the same time. | Derya Gumurdulu Seyda Erdogan Fazilet Kayaselcuk Gulsah Seydaoglu Cem K Parsak Orhan Demircan Ilhan Tuncer | 2007 | World Journal of Gastroenterology2007，13，3： | 21 |
| 2 | Interaction of L-Arginine-methyl ester and Sonic hedgehog in liver ischemia-reperfusion injury in the rats显示文摘AIM: To investigate the role of Sonic hedgehog (Shh) on the course of liver ischemia and reperfusion (I/R) in rats, and the interaction between treatment with nitric oxide donor L-Arginine-methyl ester (L-Arg) and up-regulation of Shh expression. METHODS: A total of 30 male Sprague-Dawley rats weighing 220-240 g were used in this study. Sham-control group (G1, n = 10): a sham operation was performed (except for liver I/R). I/R-untreated group (G2, n = 10): rats underwent liver ischemia for 1 h followed by reperfusion for 45 min. I/R-L-Arg group (G3, n = 10): after performing the same surgical procedure as in group 2, animals were treated with L-Arg. Liver tissues were taken for determination of malondialdehyde (MDA) levels, and biochemical and histological evaluations were made. RESULTS: Plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and γ-glutamyltranspeptidase (GGT) activities were higher in group 2 than in group 3. MDA values and the hepatic injury score decreased in the L-Arg treated group compared to the I/R-untreated group. In group 2, the hepatocytes were swollen with marked vacuolization. Group 3 rats showed well-preserved liver parenchyma, with hepatocytes extending from the central vein. The morphology of the hepatocytes and the sinusoidal structures was normal, without any signs of congestion. Mild Shh positive immunostaining was detected in group 2 animals. The expression of immunoreactive cells was increased markedly in liver tissue from I/R-L-Arg rats.CONCLUSION: Our findings suggest that Shh molecules are critical factors in the pathophysiology of inflammatory liver injury induced by I/R. In addition, NO plays an important role in the immunohistochemical expression of these molecules. | Mehmet Cudi Tuncer Hayrettin Ozturk Huseyin Buyukbayram Hulya Ozturk | 2007 | World Journal of Gastroenterology2007，13，28： | 11 |
| 3 | Retinal nerve fiber layer thickness changes in obstructive sleep apnea syndrome: one year follow-up results显示文摘·AIM: To investigate the retinal nerve fiber layer(RNFL)thickness changes in patients with obstructive sleep apnea syndrome(OSAS) for one year follow-up. To discuss the possibility of detecting tendency of glaucoma in this population by using spectral domain optical coherence tomography(3D-OCT-2000 Spectral domain).·METHODS: After polysomnographic study, all subjects(64 OSAS patients and 40 controls) underwent detailed ophthalmological examination. After these examinations,patients with glaucoma and patients who had ophthalmological and/or systemic disease were excluded from the study.Totally, 20 patients in OSAS group and five patients in controls were excluded from the study in the first examination and follow-up period. The RNFL thickness was assessed with OCT. Forty-four OSAS patients and 35 control subjects were followed up for12 mo. RNFL thickness change and OSAS patients were evaluated for severity of disease by Apnea-Hypopnea Index(AHI).·RESULTS: Forty-four OSAS patients and 35 controls were enrolled in the study. Statistically significance was found between OSAS patients and controls at the 12 thmo.Average RNFL thickness was found to be significantly lower in last measurements in OSAS patients when compared with first measurements and control subjects(P <0.001, 0.002, respectively). There was a statistically significant correlation among AHI, and RNFL thickness(P <0.05).·CONCLUSION: The results suggest that the patients with OSAS were related with a proportional decrease in the RNFL thickness. These patients should be followed up regularly for glaucomatous changes. Detecting more RNFL thinning in severe OSAS was important. | Mehmet Ozgur Zengin Ibrahim Tuncer Eyyup Karahan | 2014 | International Journal of Ophthalmology(English edition)2014，7，4： | 9 |
| 4 | Effect of Helicobacter pylori eradication on serum ghrelin and obestatin levels显示文摘AIM: To investigate changes in serum ghrelin and obestatin levels before and after Helicobacter pylori (H. pylori ) eradication. METHODS: A total of 92 patients presenting with symptoms of dyspepsia were enrolled in the study. Upper endoscopy was performed on all patients and used to diagnose H. pylori infection according to the presence of characteristic histopathological findings; seventy patients were diagnosed with H. pylori infection and the remaining 22 non-infected patients were classified as healthy controls. H. pylori eradication was accomplished by administering the classical triple therapy drug regimen, consisting of lansoprazole 30 mg bid , amoxicillin 1 g bid , and clarithromycin 500 mg tid for 14 d. The eradication of H. pylori was assessed with C14-urea breath test, which was performed at eight weeks after treatment. Levels of serum active ghrelin and obestatin were assessed at beginning of the study (prior to treatment) and after eight weeks. The levels were comparatively analyzed between the H. pylori negative control group, the H. pylori eradicated group, and the H. pylori non-eradicated group. RESULTS: A total of 92 patients, 50 females and 42 males with a mean age of 38.2 ± 11.9 years (range: 19-64), were analyzed. H. pylori eradication success was achieved in 74.3% (52/70) of H. pylori positive patients. The initial levels of ghrelin in the H. pylori positive and control cases were 63.6 ± 19.8 pg/mL and 65.1 ± 19.2 pg/mL (P=0.78), respectively, and initial obestatin levels were 771±427 pg/mL and 830 ± 296 pg/mL (P=0.19), respectively. The difference between the initial levels and the week 8 levels of ghrelin and obestatin in the control group was insignificant [4.5% (P=0.30) and -0.9% (P=0.65), respectively]. The difference between the initial and week 8 levels of ghrelin and obestatin in the H. pylori non-eradicated group were also insignificant [0.9% (P=0.64) and 5.3% (P=0.32), respectively]. The H. pylori eradicated group had a greater change in obestatin levels when compared to the control and the non-eradicated groups (148 ± 381 pg/mL vs -12±138 pg/mL and -72.8±203 pg/mL, respectively, P=0.015), while decreases in ghrelin levels were insignificant (-7.2 pg/mL vs -1.4 pg/mL and -1.9 pg/mL, respectively, P=0.52). The ghrelin/obestatin ratio for the initial and week 8 levels changed significantly in only the H. pylori eradicated group (0.11 vs 0.08, respectively, P=0.015). For overweight patients (as designated by body mass index), we observed significant increases in obestatin levels in the eradicated group as compared to non-eradicated group (201 ± 458 pg/mL vs -5 ± 81 pg/mL, respectively, P=0.02). In the H. pylori-eradicated group, the levels did not differ between the sexes for ghrelin (-6.3 ± 26.9 pg/mL vs -8.0 ± 24.0 pg/mL, respectively, P=0.97) or obestatin (210 ± 390 pg/mL vs 96 ± 372 pg/mL, respectively, P=0.23).CONCLUSION: Serum levels of ghrelin decreased while obestatin levels increased in H. pylori eradicated subjects, especially in overweight and male patients. | Celal Ulasoglu Banu Isbilen Levent Doganay Filiz Ozen Safak Kiziltas Ilyas Tuncer | 2013 | World Journal of Gastroenterology2013，19，15： | 5 |
| 5 | Voltage gated calcium channel antibody-related neurological diseases显示文摘Voltage gated calcium channel(VGCC) antibodies are generally associated with Lambert-Eaton myasthenic syndrome. However the presence of this antibody has been associated with paraneoplastic as well as nonparaneoplastic cerebellar degeneration. Most patients with VGCC-antibody-positivity have small cell lung cancer(SCLC). Lambert-Eaton myasthenic syndrome(LEMS)is an autoimmune disease of the presynaptic part of the neuromuscular junction. Its classical clinical triadis proximal muscle weakness, areflexia and autonomic dysfunction. Fifty to sixty percent of LEMS patients have a neoplasia, usually SCLC. The co-occurrence of SCLC and LEMS causes more severe and progressive disease and shorter survival than non-paraneoplastic LEMS. Treatment includes 3,4 diaminopyridine for symptomatic purposes and immunotherapy with prednisolone, azathioprine or intravenous immunoglobulin in patients unresponsive to 3,4 diaminopyridine. Paraneoplastic cerebellar degeneration(PCD) is a syndrome characterized with severe, subacute pancerebellar dysfunction. Serum is positive for VGCC antibody in 41%-44% of patients, usually with the co-occurrence of SCLC. Clinical and electrophysiological features of LEMS are also present in 20%-40% of these patients. Unfortunately, PCD symptoms do not improve with immunotherapy. The role of VGCC antibody in the immunopathogenesis of LEMS is well known whereas its role in PCD is still unclear. All patients presenting with LEMS or PCD must be investigated for SCLC. | Can Ebru Bekircan-Kurt Eda DerleÇiftçi Aslι Tuncer Kurne Banu Anlar | 2015 | World Journal of Clinical Cases2015，3，3： | 5 |
| 6 | Efficacy of ankaferd blood stopper application on nonvariceal upper gastrointestinal bleeding显示文摘AIM:To prospectively assess the hemostatic efficacy of the endoscopic topical use of ankaferd blood stopper(ABS) in active non-variceal upper gastrointestinal system(GIS) bleeding.METHODS:Endoscopy was performed on 220 patients under suspiciency of GIS bleeding.Patients with active non-variceal upper gastrointestinal bleeding(NVUGIB) with a spurting or oozing type were included.Firstly,8-10 cc of isotonic saline was sprayed to bleeding lesions.Then,8 cc of ABS was applied on lesions in which bleeding continued after isotonic saline application.The other endoscopic therapeutic methods were applied on the lesions in which the bleeding did not stop after ABS.RESULTS:Twenty-seven patients had an active NVUGIB with a spurting or oozing type and 193 patients were excluded from the study since they did not have non-variceal active bleeding.8 cc of ABS was sprayed on to the lesions of 26 patients whose bleeding continued after isotonic saline and in 19 of them,bleeding stopped after ABS.Other endoscopic treatment methods were applied to the remaining patients and the bleeding was stopped with these interventions in 6 of 7 patients.CONCLUSION:ABS is an effective method on NVUGIB,particularly on young patients with no coagulopathy.ABS may be considered as part of a combination treatment with other endoscopic methods. | Gokhan Gungor M Hakan Goktepe Murat Biyik Ilker Polat Tuncer Tuna Huseyin Ataseven Ali Demir | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，12： | 5 |
| 7 | Eicosanoid pathway in colorectal cancer:Recent updates显示文摘Enzymatic metabolism of the 20 C polyunsaturated fatty acid(PUFA) arachidonic acid(AA) occurs via the cyclooxygenase(COX) and lipoxygenase(LOX) pathways, and leads to the production of various bioactive lipids termed eicosanoids. These eicosanoids have a variety of functions, including stimulation of homeostatic responses in the cardiovascular system, induction and resolution of inflammation, and modulation of immune responses against diseases associated with chronic inflammation, such as cancer. Because chronic inflammation is essential for the development of colorectal cancer(CRC), it is not surprising that many eicosanoids are implicated in CRC. Oftentimes, these autacoids work in an antagonistic and highly temporal manner in inflammation; therefore, inhibition of the pro-inflammatory COX-2 or 5-LOX enzymes may subsequently inhibit the formation of their essential products, or shunt substrates from one pathway to another, leading to undesirable side-effects. A better understanding of these different enzymes and their products is essential not only for understanding the importance of eicosanoids, but also for designing more effective drugs that solely target the inflammatory molecules found in both chronic inflammation and cancer. In this review, we have evaluated the cancer promoting and anti-cancer roles of different eicosanoids in CRC, and highlighted the most recent literature which describes how those molecules affect not only tumor tissue, but also the tumor microenvironment. Additionally, we have attempted to delineate the roles that eicosanoids with opposing functions play in neoplastic transformation in CRC through their effects on proliferation, apoptosis, motility, metastasis, and angiogenesis. | Sinem Tuncer Sreeparna Banerjee | 2015 | World Journal of Gastroenterology2015，21，41： | 4 |
| 8 | Ultrastructural changes in hepatocytes after taurinetreatment in CCl_4 induced liver injury显示文摘AIM: To search the organelle based changes in hepatocytes after taurine treatment in experimental liver fi brosis induced by CCl_4 administration. METHODS: Thirty rats were divided into two groups. Group 1 (n = 15) was injected with CCl_4 plus taurine and Group 2 (n = 15) with CCl_4 plus saline for 12 wk. At the end of 12th wk, mitochondria, rough and smooth endoplasmic reticulum, and nuclei of hepatocytes were evaluated using a scoring system. The results were compared with histopathological f indings, as well. RESULTS: Taurine treatment reduced fi brosis scores signifi cantly as compared to placebo. Organelle injury scores decreased signifi cantly with taurine treatment. Ultrastructural and histopathological scores in both groups were in strong correlation (r = 0.931 for CCl_4 plus taurine and r = 0.899 for CCl_4 plus saline group). CONCLUSION: Organelle based transmission electron microscopy fi ndings can reflect successfully histological results as well as tissue healing in hepatocytes from hepatotoxin-induced liver fi brosis. | Ilker Tasci Nuket Mas Mehmet Refik Mas Murvet Tuncer Bilgin Comert | 2008 | World Journal of Gastroenterology2008，14，31： | 3 |
| 9 | Comparison of the Retinomax hand-held autorefractor versus table-top autorefractor and retinoscopy显示文摘AIM:To compare noncycloplegic and cycloplegic results of Retinomax measurements with findings achieved after cycloplegia using table-top autorefractor and retinoscopy.METHODS:The study included 127 patients(mean age96.7mo,range 21 to 221).Retinomax(Rmax)(Nikon Inc.,Japan)was used to obtain noncycloplegic refraction.Under cycloplegia,refraction was measured with Rmax,table-top autorefractor(TTR)(Nikon NRK 8000,Inc.,Japan)and retinoscopy.The values of sphere,spherical equivalent,cylinder and axis of cylinder were recorded for Rmax,TTR and retinoscopy in each eye.All results were analyzed statistically.RESULTS:The mean spheric values(SV),spherical equivalent values(SEV)and cylindrical values(CV)of the noncycloplegic Rmax(SV:0.64 D,SEV:0.65 D and CV:0.03 D,respectively)were found to be significantly lower than cycloplegic TTR(1.43 D,1.38 D and 0.3 D;P=0.012,P=0.011 and P=0.04,respectively)and retinoscopy(1.34 D,1.45 D and 0.23 D;P=0.04,P=0.002 and P=0.045,respectively).Mean cycloplegic SV,SEV,CV were not significantly different between Rmax and TTR,Rmax and retinoscopy,TTR and retinoscopy.Cycloplegic or noncycloplegic axis values were not different between any method.CONCLUSION:Rmax may be used successfully as a screening tool but may not be accurate enough for actual spectacle prescription.Cycloplegic Rmax measurements may be able to identify refractive error in children because of approximate results to retinoscopy. | Ibrahim Tuncer Mehmet Ozgur Zengin Eyyup Karahan | 2014 | International Journal of Ophthalmology(English edition)2014，7，3： | 3 |
| 10 | Association of human leukocyte antigen DQB1 and DRB1 alleles with chronic hepatitis B显示文摘AIM: To investigate the effect of human leukocyte antigen(HLA) DRB1 and DQB1 alleles on the inactive and advanced stages of chronic hepatitis B.METHODS: Patient records at a single institution's hepatology clinic were reviewed. Demographic data, laboratory results, endoscopy results, virological parameters, biopsy scores and treatment statuses were recorded. In total, 355 patients were eligible for thestudy, of whom 226(63.7%) were male. Overall, 82(23.1%) were hepatitis B early antigen(HBeAg) positive, 87(24.5%) had cirrhosis, and 66(18.6%) had inactive disease. The presence of DQB1 and DRB1 alleles was determined by polymerase chain reaction with sequence-specific primers. The distribution of the genotyped alleles among patients with cirrhosis and patients with chronic active hepatitis was analyzed.RESULTS: The most frequent HLA DQB1 allele was DQB1*03:01(48.2%), and the most frequent HLA DRB1 allele was DRB1*13/14(51.8%). DQB1*05:01 was more frequent in patients with active disease than in inactive patients(27% vs 9.1%; P = 0.002, Pc = 0.026). DRB1*07 was rare in patients with cirrhosis compared with non-cirrhotics(3.4% vs 16%; P = 0.002, Pc = 0.022). Older age(P < 0.001) and male gender(P = 0.008) were the other factors that affected the presence of cirrhosis. In a multivariate logistic regression analysis, DRB1*07 remained a significant negative predictor of cirrhosis(P = 0.015). A bioinformatics analysis revealed that a polymorphic amino acid sequence in DRB1*07 may alter interaction with the T-cell recognition site.CONCLUSION: This study demonstrates that HLA alleles may influence cirrhosis development and disease activity in Turkish chronic hepatitis B patients. | Levent Doganay Arta Fejzullahu Seyma Katrinli Feruze Yilmaz Enc Oguzhan Ozturk Yasar Colak Celal Ulasoglu Ilyas Tuncer Gizem Dinler Doganay | 2014 | World Journal of Gastroenterology2014，20，25： | 3 |
| 11 | Gastrointestinal and hepatic complications of hematopoietic stem cell transplantation显示文摘Recognition and management of gastrointestinal and hepatic complications of hematopoietic stem cell transplantation has gained increasing importance as indications and techniques of transplantation have expanded in the last few years.The transplant recipient is at risk for several complications including conditioning chemotherapy related toxicities,infections,bleeding,sinusoidal obstruction syndrome,acute and chronic graftversus-host disease(GVHD) as well as other long-term problems.The severity and the incidence of many complications have improved in the past several years as the intensity of conditioning regimens has diminished and better supportive care and GVHD prevention strategies have been implemented.Transplant clinicians,however,continue to be challenged with problems arising from human leukocyte antigen-mismatched and unrelated donor transplants,expanding transplant indications and age-limit.This review describes the most commonly seen transplant related complications,focusing on their pathogenesis,differential diagnosis and management. | Hande H Tuncer Naveed Rana Cannon Milani Angela Darko Samer A AlHomsi | 2012 | World Journal of Gastroenterology2012，18，16： | 3 |
| 12 | Analysis of serum antibody profile against H pylori VacA and CagA antigens in Turkish patients with duodenal ulcer显示文摘AIM: To investigate the frequency of seropositivity aga- inst CagA, VacA proteins and to determine their indepen- dent effects on the development of duodenal ulcer (DU) in Turkish patients. METHODS: The study was designed as a prospective one from a tertiary referral hospital. Dyspeptic patients who were referred to our endoscopy unit for upper gas- trointestinal endoscopy between June 2003 and March 2004 and diagnosed to have DU or nonulcer dyspepsia (NUD) were included. Biopsies from the antrum and body of the stomach were taken in order to assess the current H pylori status by histology, rapid urease test and culture. Fasting sera were obtained from all patients and H pylori status of all sera was determined by IgG antibo- dies using an enzyme-linked immunosorbent assay (ELI- SA) kit. All seropositive patients were further analysed using Western blot assays detecting IgG antibodies aga- inst CagA and VacA proteins. The χ2 test was used for statistical comparison of the values and age-sex adjusted multiple regression analysis was used to determine the independent effects of CagA and VacA seropositivities on the development of DU. RESULTS: Sixty-three patients with DU and 62 patients with NUD were eligible for the final analysis. Seropositi- vity for anti-CagA was detected in 51 of 62 (82%), andin 55 of 63 (87%) patients with NUD and DU, respec- tively (p = no significance), and seropositivity for anti- VacA was found in 25 of 62 (40% ) and in 16 of 63 (25%) patients, with NUD and DU, respectively. CONCLUSION: These findings suggest that none of the- se virulence factors is associated with the development of DU in the studied Turkish patients with dyspepsia. | Yusuf Erzin Sibel Altun Ahmet Dobrucali Mustafa Aslan Sibel Erdamar Ahmet Dirican Murat Tuncer Bekir Kocazeybek | 2006 | World Journal of Gastroenterology2006，12，42： | 3 |
| 13 | Red cell distribution width and nonalcoholic steatohepatitis显示文摘Red cell distribution width is a measure of deviation of the volume of red blood cells.It is a marker of anisocytosis and often used to evaluate the possible causes of anemia.Elevated red cell distribution width levels are also associated with acute and chronic inflammatory responses.In nonalcoholic steatohepatitis,inflammation is accompanied with steatosis.For assuming red cell distribution width as a marker of nonalcoholic steatohepatitis,intervening factors such as levels of inflammatory markers should also be evaluated. | Yasemin Gulcan Kurt Tuncer Cayci Fevzi Nuri Aydin Mehmet Agilli | 2014 | World Journal of Gastroenterology2014，20，43： | 2 |

| 17 | Ectopic liver tissue (choristoma) on the gallbladder: Acomprehensive literature review显示文摘BACKGROUND Liver tissue situated outside the liver with a hepatic connection is usually calledan accessory liver, and that without a connection to the mother liver, is calledectopic liver tissue.AIM To identify studies in the literature on ectopic liver tissue located on thegallbladder surface or mesentery.METHODS We present two patients and review published articles on ectopic liver tissuelocated on the gallbladder surface accessed via PubMed, MEDLINE, GoogleScholar, and Google databases. Keywords used included accessory liver lobe,aberrant liver tissue, ectopic liver tissue, ectopic liver nodule, heterotopic livertissue, hepatic choristoma, heterotopic liver tissue on the gallbladder, and ectopicliver tissue on the gallbladder. The search included articles published before June2020 with no language restriction. Letters to the editor, case reports, reviewarticles, original articles, and meeting presentations were included in the search.Articles or abstracts containing adequate information on age, sex, history of liverdisease, preliminary diagnosis, radiologic tools, lesion size, surgical indication,surgical procedure, and histopathological features of ectopic liver tissue wereincluded in the study.RESULTS A total of 72 articles involving 91 cases of ectopic liver tissue located on the gallbladder surface or mesentery were analyzed. Of these 91 patients, 62 werefemale and 25 were male (no gender available for 4 patients), and the age rangewas 5 d to 91 years. Forty-nine patients underwent surgery for chroniccholecystitis or cholelithiasis, and 14 patients underwent surgery for acutecholecystitis. The remaining 28 patients underwent laparotomy for other reasons.Cholecystectomy was laparoscopic in 69 patients and open in 11 patients. Theremaining 19 patients underwent various other surgical procedures such asautopsy, liver transplantation, living donor hepatectomy, Whipple procedure, andliver segment V resection. Histopathologically, hepatocellular carcinoma wasdetected in the ectopic liver tissue of one patient.CONCLUSION Ectopic liver tissue is a rare developmental anomaly which is usually detectedincidentally. Although most studies suggest that ectopic liver located outside thegallbladder has a high risk of hepatocellular carcinoma, this is not reflected instatistical analysis. | Sami Akbulut Khaled Demyati Felat Ciftci Cemalettin Koc Adem Tuncer Emrah Sahin Nese Karadag Sezai Yilmaz | 2020 | World Journal of Gastrointestinal Surgery2020，12，12： | 2 |
