| 1 | Type 2 diabetes mellitus and CA 19-9 levels显示文摘AIM:To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age-and gender-matched control subjects. METHODS:We recorded duration of diabetes and examined fasting glucose levels,HbA1c levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls.Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups. RESULTS:The average CA 19-9 level was 46.0±22.4 U/mL for diabetic patients whereas it was 9.97±7.1 U/mL for the control group(P<0.001).Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age,gender,glucose level and HbA1c level(t=8.8,P<001).Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation.For all patients,abdominal CT showed no pancreatic abnormalities. CONCLUSION:CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic,upper gastrointestinal tract,ovarian hepatocellular,and colorectal cancers,as well as in inflammatory conditions of the hepatobiliary system,biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer,which is increasing its incidence and has one of the lowest survival rates of all cancers.CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes.We propose that a higher cut- off value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction. | Oya Uygur-Bayramicli Resat Dabak Ekrem Orbay Can Dolapclo■lu Mehmet Sargin Gamze Kilico■lu Yüksel Güleryüzlü Alpaslan Mayada■li | 2007 | World Journal of Gastroenterology2007，13，40： | 63 |
| 2 | Relationship between serum cytokine levels and histopathological changes of liver in patients with hepatitis B显示文摘AIM: To investigate whether there was a relationship between the liver functions and fibrosis scores of hepatitis B patients and their TNF-α, IFN-γ, IL-4, and TGF-β1 serum levels based on the studies of liver biopsies. METHODS: Thirty patients with chronic hepatitis B (CHB)receiving no treatment and 30 healthy individuals with negative hepatitis serology and normal values of liver biochemistry were studied. After serum samples of the patients were collected, liver needle biopsy was performed on each patient. Cytokine levels were studied by ELISA.The biopsy materials were scored based on Knodell's histological activity index.RESULTS: In comparison of cytokine levels between CHB patients and control group, TNF-α, IL-4, and TGF-β1 levels of the patients were higher in CHB patients than in the controls, while IFN-γ level was lower in the patients than in the controls. There were significant differences between the groups in TNF-α, IL-4, TGF-β1, and IFN-γ (P<0.005,0.03, 0.002, 0.0001, respectively). There was a negativecorrelation between TGF-β1 and IL-4 and IFN-γ (P<0.05),TNF-α and the other cytokines and IFN-γ and IL-4 were not correlated (P>0.05). TGF-β1 was correlated with fibrosis (P<0.05). Liver necroinflammatory activity and fibrosis and TNF-α, IL-4, and IFN-γ were not correlated (P>0.05).CONCLUSION: In the course of HBV infection and its chronic progress, cytokines play an important role. IL-4and IFN-γ are effective in the chronic progression, whileTGF-β1 is effective in the development of fibrosis. Serum cytokine levels may be effective tools in the estimation of chronic progression and fibrosis development. | Nusret Akpolat Seyfettin Yahsi Ahmet Godekmerdan Kutbettin Demirbag Mehmet Yalniz | 2005 | World Journal of Gastroenterology2005，11，21： | 46 |
| 3 | Comparison of early enteral nutrition in severe acute pancreatitis with prebiotic fiber supplementation versus standard enteral solution:A prospective randomized double-blind study显示文摘AIM: To compare the benefi cial effects of early enteral nutrition (EN) with prebiotic fiber supplementation in patients with severe acute pancreatitis (AP).METHODS: Thirty consecutive patients with severe AP, who required stoppage of oral feeding for 48 h, were randomly assigned to nasojejunal EN with or without prebiotics. APACHE Ⅱ score, Balthazar’s CT score and CRP were assessed daily during the study period.RESULTS: The median duration of hospital stay was shorter in the study group [10 ± 4 (8-14) d vs 15 ± 6 (7-26) d] (P < 0.05). The median value of days in intensive care unit was also similar in both groups [6 ± 2 (5-8) d vs 6 ± 2 (5-7) d]. The median duration of EN was 8 ± 4 (6-12) d vs 10 ± 4 (6-13) d in the study and control groups, respectively (P > 0.05). Deaths occurred in 6 patients (20%), 2 in the study group and 4 in the control group. The mean duration of APACHE Ⅱ normalization (APACHE Ⅱ score < 8) was shorter in the study group than in the control group (4 ± 2 d vs 6.5 ± 3 d, P < 0.05). The mean duration of CRP normalization was also shorter in the study group than in the control group (7 ± 2 d vs 10 ± 3 d, P < 0.05).CONCLUSION: Nasojejunal EN with prebiotic fiber supplementation in severe AP improves hospital stay, duration nutrition therapy, acute phase response and overall complications compared to standard EN therapy. | Tarkan Karakan Meltem Ergun Ibrahim Dogan Mehmet Cindoruk Selahattin Unal | 2007 | World Journal of Gastroenterology2007，13，19： | 50 |

| 5 | Recent developments and innovations in gastric cancer显示文摘Gastric cancer has an important place in the worldwide incidence of cancer and cancer-related deaths. It can metastasize to the lymph nodes in the early stages, and lymph node metastasis is an important prognostic factor. Surgery is a very important part of gastric cancer treatment. A D2 lymphadenectomy is the standard surgical treatment for c T1N+ and T2-T4 cancers, which are potentially curable. Recently, the TNM classification system was reorganized, and the margins for gastrectomy and lymphadenectomy were revised. Endoscopic, laparoscopic and robotic treatments of gastric cancer have progressed rapidly with development of surgical instruments and techniques, especially in Eastern countries. Different endoscopic resection techniques have been identified, and these can be divided into two main categories: endoscopic mucosal resection and endoscopic submucosal dissection. Minimally invasive surgery has been reported to be safe and effective for early gastric cancer, and it can be successfully applied to advanced gastric cancer with increasing experience. Cytoreductive surgery and hypertherm?c intraper?toneal chemotherapy were developed as a combined treatment modality from the results of experimental and clinical studies. Also, hyperthermia increases the antitumor activity and penetration of chemotherapeutics. Trastuzumab which is a monoclonal antibody interacts with human epidermal growth factor(HER) 2 and is related to gastric carcinoma. The anti-tumor mechanism of trastuzumab is not clearly known, but mechanisms such as interruption of the HER2-mediated cell signaling pathways and cell cycle progression have been reported previously. H. pylori is involved in 90% of all gastric malignancies and Japanese guidelines strongly recommend that all H. pylori infections should be eradicated regardless of the associated disease. In this review, we present innovations discussed in recent studies. | Mehmet Mihmanli Enver Ilhan Ufuk Oguz Idiz Ali Alemdar Uygar Demir | 2016 | World Journal of Gastroenterology2016，22，17： | 29 |
| 6 | Inflammatory pathways of importance for management of inflammatory bowel disease显示文摘Inflammatory bowel disease(IBD)is a group of chronic disorders of the gastrointestinal tract comprising Crohn’s disease(CD)and ulcerative colitis(UC).Their etiologies are unknown,but they are characterised by an imbalanced production of pro-inflammatory mediators,e.g.,tumor necrosis factor(TNF)-α,as well as increased recruitment of leukocytes to the site of inflammation.Advantages in understanding the role of the inflammatory pathways in IBD and an inadequate response to conventional therapy in a large portion of patients,has over the last two decades lead to new therapies which includes the TNF inhibitors(TNFi),designed to target and neutralise the effect of TNF-α.TNFi have shown to be efficient in treating moderate to severe CD and UC.However,convenient alternative therapeutics targeting other immune pathways are needed for patients with IBD refractory to conventional therapy including TNFi.Indeed,several therapeutics are currently under development,and have shown success in clinical trials.These include antibodies targeting and neutralising interleukin-12/23,small pharmacologic Janus kinase inhibitors designed to block intracellular signaling of several pro-inflammatory cytokines,antibodies targeting integrins,and small anti-adhesion molecules that block adhesion between leukocytes and the intestinal vascular endothelium,reducing their infiltration into the inflamed mucosa.In this review we have elucidated the major signaling pathways of clinical importance for IBD therapy and highlighted the new promising therapies available.As stated in this paper several new treatment options are under development for the treatment of CD and UC,however,no drug fits all patients.Hence,optimisations of treatment regimens are warranted for the benefit of the patients either through biomarker establishment or other rationales to maximise the effect of the broad range of mode-of-actions of the present and future drugs in IBD. | Jannie Pedersen Mehmet Coskun Christoffer Soendergaard Mohammad Salem Ole Haagen Nielsen | 2014 | World Journal of Gastroenterology2014，20，1： | 28 |
| 7 | Efficacy and safety of tenofovir disoproxil fumarate in pregnancy for the prevention of vertical transmission of HBV infection显示文摘AIM:To evaluate the effects of tenofovir disoproxil fumarate(TDF)use during late pregnancy to reduce hepatitis B virus(HBV)transmission in highly viremic mothers.METHODS:This retrospective study included 45 pregnant patients with hepatitis B e antigen(+)chronic hepatitis B and HBV DNA levels>107copies/mL who received TDF 300 mg/d from week 18 to 27 of gestation(n=21).Untreated pregnant patients served as controls(n =24).All infants received 200 IU of hepatitis B immune globulin(HBIG)within 24 h postpartum and 20μg of recombinant HBV vaccine at 4,8,and 24 wk.Perinatal transmission rate was determined by hepatitis B surface antigen and HBV DNA results in infants at week 28.RESULTS:At week 28,none of the infants of TDFtreated mothers had immunoprophylaxis failure,whereas2(8.3%)of the infants of control mothers had immunoprophylaxis failure(P=0.022).There were no differences between the groups in terms of adverse events in mothers or congenital deformities,gestational age,height,or weight in infants.At postpartum week 28,significantly more TDF-treated mothers had levels of HBV DNA<250 copies/mL and normalized alanine aminotransferase compared with controls(62%vs none,P<0.001;82%vs 61%,P=0.012,respectively).CONCLUSION:TDF therapy during the second or third trimester reduced perinatal transmission rates of HBV and no adverse events were observed in mothers or infants. | Mustafa Kemal Celen Duygu Mert Müzeyyen Ay Tuba Dal Safak Kaya Necmettin Yildirim Serda Gulsun Tunga Barcin Sevgi Kalkanli Mehmet Sinan Dal Celal Ayaz | 2013 | World Journal of Gastroenterology2013，19，48： | 26 |
| 8 | Type 2 diabetes mellitus affects eradication rate of Helicobacter pylori显示文摘AIM: To study the eradication rate of Helicobacter pylori (Hp) in a group of type 2 diabetes and compared it with an age and sex matched non-diabetic group.METHODS: 40 diabetic patients (21 females, 19 males;56±7 years) and 40 non-diabetic dyspeptic patients (20females, 20 males; 54±9 years) were evaluated. Diabetic patients with dyspeptic complaints were referred for upper gastrointestinal endoscopies; 2 corpus and 2 antral gastric biopsy specimens were performed on each patient. Patients with positive Hp results on histopathological examination comprised the study group. Non-diabetic dyspeptic patients seen at the Gastroenterology Outpatient Clinic and with the same biopsy and treatment protocol formed the control group.A triple therapy with amoxycillin (1 g b.i.d), clarithromycin (500 mg b.i.d) and omeprazole (20 mg b.i.d.) was given to both groups for 10 days. Cure was defined as the absence of Hp infection assessed by corpus and antrum biopsies in control upper gastrointestinal endoscopies performed 6weeks after completing the antimicrobial therapy.RESULTS: The eradication rate was 50 % in the diabetic group versus 85 % in the non-diabetic control group (P<0.001).CONCLUSION: Type 2 diabetic patients showed a significantly lower eradication rate than controls which may be due to changes in microvasculature of the stomach and to frequent antibiotic usage because of recurrent bacterial infections with the development of resistant strains. | Mehmet Sarg■n OyaUygur-Bayramili Haluk Sarg■n Ekrem Orbay Dilek Yavuzer Ali Yayla | 2003 | World Journal of Gastroenterology2003，9，5： | 25 |
| 9 | Effect of preoperative immunonutrition and other nutrition models on cellular immune parameters显示文摘AIM:To evaluate the effects of preoperative immunonutrition and other nutrition models on the cellular immunity parameters of patients with gastrointestinal tumors before surgical intervention.In addition,effects on postoperative complications were examined. METHODS:Patients with gastrointestinal tumors were randomized into 3 groups.The immunonutrition group received a combination of arginine,fatty acids and nucleotides.The second and third group received normal nutrition and standard enteral nutrition,respectively.Nutrition protocols were administered for 7 d prior to the operation.Nutritional parameters,in particular prealbumin levels and lymphocyte subpopulations(CD4+,CD8+,CD16+/56+,and CD69 cells)were evaluated before and after the nutrition protocols.Groups were compared in terms of postoperative complications and duration of hospital stay. RESULTS:Of the 42 patients who completed thestudy,16 received immunonutrition,13 received normal nutrition and 13 received standard enteral nutrition. prealbumin values were low in every group,but this parameter was improved after the nutritional protocol only in the immunonutrition group(13.64±8.83 vs 15.98±8.66,P=0.037).Groups were similar in terms of CD4+,CD16+/56,and CD69+prior to the nutritional protocol;whereas CD8+was higher in the standard nutrition group compared to the immunonutrition group.After nutritional protocols,none of the groups had an increase in their lymphocyte subpopulations.Also,groups did not differ in terms of postoperative complications and postoperative durations of hospital stay. CONCLUSION:Preoperative immunonutrition provided a significant increase in prealbumin levels,while it did not significantly alter T lymphocyte subpopulation counts,the rate of postoperative complications and the duration of hospital stay. | Yusuf Gunerhan Neset Koksal Umit Yasar Sahin Mehmet Ali Uzun Emel Ek■ioglu-Demiralp | 2009 | World Journal of Gastroenterology2009，15，4： | 21 |
| 10 | miR-20b, miR-98, miR-125b-1*, and let-7e* as new potential diagnostic biomarkers in ulcerative colitis显示文摘AIM:To use microarray-based miRNA profiling of colonic mucosal biopsies from patients with ulcerative colitis (UC), Crohn's disease (CD), and controls in order to identify new potential miRNA biomarkers in inflammatory bowel disease. METHODS:Colonic mucosal pinch biopsies from the descending part were obtained endoscopically from patients with active UC or CD, quiescent UC or CD, as well as healthy controls. Total RNA was isolated and miRNA expression assessed using the miRNA microarray Geniom Biochip miRNA Homo sapiens (Febit GmbH, Heidelberg, Germany). Data analysis was carried out by principal component analysis and projection to latent structure-discriminant analysis using the SIMCA-P+12 software package (Umetrics, Umea, Sweden). The microarray data were subsequently validated by quantitative real-time polymerase chain reaction (qPCR) performed on colonic tissue samples from active UC patients (n = 20), patients with quiescent UC (n = 19), and healthy controls (n = 20). The qPCR results were analyzed with Mann-WhitneyU test.In silico prediction analysis were performed to identify potential miRNA target genes and the predicted miRNA targets were then compared with all UC associated susceptibility genes reported in the literature. RESULTS:The colonic mucosal miRNA transcriptome differs significantly between UC and controls, UC and CD, as well as between UC patients with mucosal inflammation and those without. However, no clear differences in the transcriptome of patients with CD and controls were found. The miRNAs with the strongest differential power were identified (miR-20b, miR-99a, miR-203, miR-26b, and miR-98) and found to be upregulated more than a 10-fold in active UC as compared to quiescent UC, CD, and controls. Two miRNAs, miR-125b-1* and let-7e*, were up-regulated more than 5-fold in quiescent UC compared to active UC, CD, and controls. Four of the seven miRNAs (miR-20b, miR-98, miR-125b-1*, and let-7e*) were validated by qPCR and found to be specifically upregulated in patients with UC. Usingin silico analysis we found several predicted pro-inflammatory target genes involved in various pathways, such as mitogen-activated protein kinase and cytokine signaling, which are both key signaling pathways in UC.CONCLUSION:The present study provides the first evidence that miR-20b, miR-98, miR-125b-1*, and let7e* are deregulated in patients with UC. The level of these miRNAs may serve as new potential biomarkers for this chronic disease. | Mehmet Coskun Jacob Tveiten Bjerrum Jakob Benedict Seidelin Jesper Thorvald Troelsen JΦrgen Olsen Ole Haagen Nielsen | 2013 | World Journal of Gastroenterology2013，19，27： | 19 |
| 11 | Radical vs conservative surgery for hydatid liver cysts:Experience from single center显示文摘AIM:To compare the efficacy and safety of radical and conservative surgical interventions for liver hydatid disease.METHODS:The study comprised 59 patients in two groups who had undergone radical and conservative surgical procedures for liver hydatid disease in our department between 2004 and 2009. Preoperative diagnostic tools,medical treatments,demographic and clinical characteristics,postoperative follow-up,and recurrence were compared in both groups. RESULTS:This non-randomized retrospective studyincluded 59 patients who had undergone liver hydatid disease surgery. The radical technique was used in 18 patients (mean age:42.1 ± 13.5 years,seven male,11 female),and the conservative technique was used in 41 patients (mean age:43.5 ± 13.9 years,17 male,24 female). The follow-up period ranged from 3 to 58 mo. Although operative time was significantly shorter in the conservative group (P < 0.001),recurrence was significantly reduced in the radical group (P = 0.045). No statistically significant differences were found in terms of hospitalization duration,cyst count and size,location,postoperative complications,scolicidal solution usage,or follow-up duration between the two groups.CONCLUSION:The more effective method for pre-venting postoperative recurrence is radical surgery. En-doscopic retrograde cholangiopancreatography for bile leakage in the early postoperative period may decrease the requirement for repeat surgery. | Sami Akbulut Ayhan Senol Arsenal Sezgin Bahri Cakabay Mehmet Dursun Omer Satici | 2010 | World Journal of Gastroenterology2010，16，8： | 19 |
| 12 | MicroRNAs in inflammatory bowel disease-pathogenesis,diagnostics and therapeutics显示文摘The pathogenesis of inflammatory bowel disease (IBD) is complex and largely unknown. Until recently, research has focused on the study of protein regulators in inflammation to reveal the cellular and molecular networks in the pathogenesis of IBD. However, in the last few years, new and promising insights have been generated from studies describing an association between an altered expression of a specific class of non-coding RNAs, called microRNAs (miRs or miRNAs) and IBD. The short (approximately 22 nucleotides), endogenous, single-stranded RNAs are evolutionary conserved inanimals and plants, and regulate specific target mRNAs at the post-transcriptional level. MiRNAs are involved in several biological processes, including development, cell differentiation, proliferation and apoptosis. Furthermore, it is estimated that miRNAs may be responsible for regulating the expression of nearly one-third of the genes in the human genome. Thus, miRNA deregulation often results in an impaired cellular function, and a disturbance of downstream gene regulation and signaling cascades, suggesting their implication in disease etiology. Despite the identification of more than 1900 mature human miRNAs, very little is known about their biological functions and functional targets. Recent studies have identified dysregulated miRNAs in tissue samples of IBD patients and have demonstrated similar differences in circulating miRNAs in the serum of IBD patients. Thus, there is great promise that miRNAs will aid in the early diagnosis of IBD, and in the development of personalized therapies. Here, we provide a short review of the current state-of-the-art of miRNAs in IBD pathogenesis, diagnostics and therapeutics. | Mehmet Coskun Jacob Tveiten Bjerrum Jakob Benedict Seidelin Ole Haagen Nielsen | 2012 | World Journal of Gastroenterology2012，18，34： | 18 |
| 13 | Effect of autotransfusion system on tumor recurrence and survival in hepatocellular carcinoma patients显示文摘AIM:To investigate the therapeutic efficacy and safety of continuous autotransfusion system(CATS) during liver transplantation of hepatocellular carcinoma patients.METHODS:Eighty-three hepatocellular carcinoma(HCC) patients who underwent liver transplantation with intraoperative CATS(n = 24,CATS group) and without(n = 59,non-CATS group) between April 2006 and November 2011 at the Liver Transplant Institute of Inonu University were analyzed retrospectively.Postoperative HCC recurrence was monitored by measuring alpha-fetoprotein(AFP) levels at 3-mo intervals and performing imaging analysis by thoracoabdominal multidetector computed tomography at 6-month intervals.Inter-group differences in recurrence and correlations between demographic,clinical,and pathological data were assessed by ANOVA and χ 2 tests.Overall and disease-free survivals were calculated by the univariate Kaplan-Meier method.RESULTS:Of the 83 liver transplanted HCC patients,89.2% were male and the overall mean age was 51.3 ± 8.9 years(range:18-69 years).The CATS and nonCATS groups showed no statistically significant differences in age,sex ratio,body mass index,underlying disease,donor type,graft-to-recipient weight ratio,Child-Pugh and Model for End-Stage Liver Disease scores,number of tumors,tumor size,AFP level,Milan and University of California San Francisco selection criteria,tumor differentiation,macrovascular invasion,median hospital stay,recurrence rate,recurrence site,or mortality rate.The mean follow-up time of the nonCATS group was 17.9 ± 12.8 mo,during which systemic metastasis and/or locoregional recurrence developed in 25.4% of the patients.The mean follow-up time for the CATS group was 25.8 ± 15.1 mo,during which systemic metastasis and/or locoregional recurrence was detected in 29.2% of the patients.There was no significant difference between the CATS and non-CATS groups in recurrence rate or site.Additionally,no significant differences existed between the groups in overall or disease-free survival.CONCLUSION:CATS is a safe procedure and may decrease the risk of tumor recurrence in HCC patients. | Sami Akbulut Cuneyt Kayaalp Mehmet Yilmaz Volkan Ince Dincer Ozgor Koray Karabulut Cengiz Eris Huseyin Ilksen Toprak Cemalettin Aydin Sezai Yilmaz | 2013 | World Journal of Gastroenterology2013，19，10： | 17 |
| 14 | Internal biliary fistula due to cholelithiasis:A single-centre experience显示文摘AIM: To discuss about the perioperative problems encountered in patients with internal biliary fistula (IBF) caused by cholelithiasis. METHODS: In our hospital, 4 130 cholecystectomies were carried out for symptomatic cholelithiasis from January 2000 to March 2004 and only 12 patients were diagnosed with IBF. The perioperative data of these 12 IBF patients were analyzed retrospectively. RESULTS: The incidence of IBF due to cholelithiasis was nearly 0.3%. The mean age was 57 years. Most of the patients presented with non-specific complaints. Only two patients were considered to have IBF when gallstone ileus was observed during the investigations. Nine patients underwent emergency laparotomy with a pre-operative diagnosis of acute abdomen. In the remaining three patients, elective laparoscopic cholecystectomy was converted to open surgery after identification of IBF. Ten patients had cholecystoduodenal fistula and two patients had cholecystocholedochal fistula. The mean hospital stay was 13 d. Two wound infections, three bile leakages and three mortalities were observed. CONCLUSION: Cholecystectomy has to be performed in early stage in the patients who were diagnosed as cholelithiasis to prevent the complications like IBF which is seen rarely. Suspicion of IBF should be kept in mind, especially in the case of difficult dissection during cholecystectomy and attention should be paid in order to prevent iatrogenic injuries. | Arife Polat Duzgun Mehmet Mahir Ozmen Mehmet Vasfi Ozer Faruk Coskun | 2007 | World Journal of Gastroenterology2007，13，34： | 15 |

| 16 | Insulin resistance in H pylori infection and its association with oxidative stress显示文摘AIM: To determine the insulin resistance (IR) and oxidative status in H pylori infection and to find out if there is any relationship between these parameters and insulin resistance. METHODS: Fifty-five H pylori positive and 48 H pylori negative patients were enrolled. The homeostasis model assessment (HOMA) was used to assess insulin resistance. Serum total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined in all subjects. RESULTS: The total antioxidant capacity was significantly lower in H pylori positive group than in H pylori negative group (1.36 ± 0.33 and 1.70 ± 0.50, respectively; P < 0.001), while the total oxidant status and oxidative stress index were significantly higher in H pylori positive group than in H pylori negative group (6.79 ± 3.40 and 5.08 ± 0.95, and 5.42 ± 3.40 and 3.10 ± 0.92, respectively; P < 0.001). Insulin resistance was significantly higher in H pylori positive group than in H pylori negative group (6.92 ± 3.86 and 3.61 ± 1.67, res- pectively; P < 0.001). Insulin resistance was found to be significantly correlated with total antioxidant capacity (r = -0.251, P < 0.05), total oxidant status (r = 0.365, P < 0.05), and oxidative stress index (r = 0.267, P < 0.05). CONCLUSION: Insulin resistance seems to be associated with increased oxidative stress in H pylori infection. Further studies are needed to clarify the mechanisms underlying this association and elucidate the effectof adding antioxidant vitamins to H pylori eradication therapy on insulin resistance during H pylori infection. | Mehmet Aslan Mehmet Horoz Yasar Nazligul Cengiz Bolukbas F Fusun Bolukbas Sahbettin Selek Hakim Celik Ozcan Erel | 2006 | World Journal of Gastroenterology2006，12，42： | 15 |
| 17 | Impact of liver steatosis on response to pegylated interferon therapy in patients with chronic hepatitis B显示文摘AIM: To evaluate the impact of liver steatosis upon response to given therapy in chronic hepatitis B (CHB) patients. METHODS: 84 consecutive CHB patients treated with 48-wk PEGylated interferon (PEG-IFN) therapy were enrolled. Baseline characteristics and sustained viral response (SVR) to PEG-IFN therapy were evaluated. RESULTS:Mean body mass index (BMI) was 27.36 ± 4.4 kg/m 2 . Six (7.1%) had hypertension and three (3.5%) had diabetes mellitus. Steatosis was present in 22.6% (19/84) of liver biopsy samples. Age, BMI, and triglyceride levels of the patients with hepatic steatosis were significantly higher than those without hepatic steatosis (P < 0.05). SVR to PEG-IFN therapy was 21.4% (18/84). Sixteen of these 18 CHB patients with SVR (88.9%) did not have any histopathologically determined steatosis. On the other hand, only two of the 19 CHB patients with hepatic steatosis had SVR (10.5%). Although the SVR rate observed in patients without steatosis (16/65, 24.6%) was higher compared to those with steatosis (2/19, 10.5%), the difference was not statistically significant (P > 0.05). CONCLUSION:Occurrence of hepatic steatosis is significantly high in CHB patients and this association leads to a trend of decreased, but statistically insignificant, SVR rates to PEG-IFN treatment. | Fehmi Ates Mehmet Yalnlz Saadet Alan | 2011 | World Journal of Gastroenterology2011，17，40： | 15 |

| 20 | Graft-versus-host disease after liver transplantation:A comprehensive literature review显示文摘AIM:To determine the factors affecting mortality in patients who developed graft-versus-host disease (GvH) after liver transplantation (LT) METHODS:We performed a review of studies of GvH following LT published in the English literature and accessed the PubMed, Medline, EBSCO, EMBASE, and Google Scholar databases Using relevant search phrases, 88 articles were identified. Of these, 61 articles containing most of the study parameters were considered eligible for the study. Risk factors were first examined using a univariate Kaplan-Meier model, and variables with a significant association (P < 0 05) were then subjected to multivariate analyses using a Cox proportional-hazards model RESULTS:The 61 articles reported 87 patients, 58 male and 29 female, mean age, 40.4 ± 15.5 years (range:8 mo to 74 years), who met the inclusion criteria for the present study. Deaths occurred in 59 (67.8%) patients, whereas 28 (32.2%) survived after a mean follow-up period of 280.8 ± 316.2 d (range:27-2285 d). Among the most frequent symptoms were rash (94.2%), fever (66.6%), diarrhea (54%), and pancytopenia (54%). Theaverage time period between LT and first symptom onset was 60.6 ± 190.1 d (range: 2-1865 d). The Kaplan-Meier analysis revealed that pancytopenia (42.8% vs 59.3%,P = 0.03), diarrhea (39.2%vs 61.0%,P = 0 04), age difference between the recipient and the donor (14.6 ± 3.1 yearsvs 22.6 ± 2.7 years,P < 0.0001), and time from first symptom occurrence to diagnosis or treatment (13.3 ± 2.6 mo vs 15.0 ± 2.3 mo, P < 0.0001) were significant factors affecting mortality, whereas age, sex, presence of rash and fever, use of immunosuppressive agents, acute rejection before GvH , etiological causes, time of onset, and donor type were not associated with mortality risk The Cox proportional-hazards model, determined that an age difference between the recipient and donor was an independent risk factor (P = 0 03; hazard ratio, 7.395, 95% confidence interval, 1.2-46.7). CONCLUSION:This study showed that an age difference between the recipient and donor is an independent risk factor for mortality in patients who develop GvH after LT. | Sami Akbulut Mehmet Yilmaz Sezai Yilmaz | 2012 | World Journal of Gastroenterology2012，18，37： | 14 |
