| 1 | 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 |

| 5 | Cytoprotective effects of amifostine,ascorbic acid and N-acetylcysteine against methotrexate-induced hepatotoxicity in rats显示文摘AIM:To investigate the potential role of oxidative stress and the possible therapeutic effects of N-acetyl cysteine(NAC),amifostine(AMF)and ascorbic acid(ASC)in methotrexate(MTX)-induced hepatotoxicity.METHODS:An MTX-induced hepatotoxicity model was established in 44 male Sprague Dawley rats by administration of a single intraperitoneal injection of20 mg/kg MTX.Eleven of the rats were left untreated(Model group;n=11),and the remaining rats were treated with a 7-d course of 50 mg/kg per day NAC (MTX+NAC group;n=11),50 mg/kg per single dose AMF(MTX+AMF group;n=11),or 10 mg/kg per day ASC(MTX+ASC group;n=11).Eleven rats that received no MTX and no treatments served as the negative control group.Structural and functional changes related to MTX-and the various treatments were assessed by histopathological analysis of liver tissues and biochemical assays of malondialdehyde(MDA),superoxide dismutase(SOD),catalase,glutathione(GSH)and xanthine oxidase activities and of serum levels of aspartate aminotransferase,alanine aminotransferase,alkaline phosphatase and total bilirubin.RESULTS:Exposure to MTX caused structural and functional hepatotoxicity,as evidenced by significantly worse histopathological scores[median(range)injury score:control group:1(0-3)vs 7(6-9),P=0.001]and significantly higher MDA activity[409(352-466)nmol/g vs 455.5(419-516)nmol/g,P<0.05].The extent of MTX-induced perturbation of both parameters was reduced by all three cytoprotective agents,but only the reduction in hepatotoxicity scores reached statistical significance[4(3-6)for NAC,4.5(3-5)for AMF and 6(5-6)for ASC;P=0.001,P=0.001 and P<0.005vs model group respectively].Exposure to MTX also caused a significant reduction in the activities of GSH and SOD antioxidants in liver tissues[control group:3.02(2.85-3.43)μmol/g and 71.78(61.88-97.81)U/g vs model group:2.52(2.07-3.34)μmol/g and 61.46(58.27-67.75)U/g,P<0.05];however,only the NAC treatment provided significant increases in these antioxidant enzyme activities[3.22(2.54-3.62)μmol/g and 69.22(61.13-100.88)U/g,P<0.05 and P<0.01vs model group respectively].CONCLUSION:MTX-induced structural and functional damage to hepatic tissues in rats may involve oxidative stress,and cytoprotective agents(NAC>AMF>ASC)may alleviate MTX hepatotoxicity. | Sami Akbulut Hulya Elbe Cengiz Eris Zumrut Dogan Gulten Toprak Emrah Otan Erman Erdemli Yusuf Turkoz | 2014 | World Journal of Gastroenterology2014，20，29： | 3 |
