| 2 | Subclinical abnormal glucose tolerance is a predictor of death in liver cirrhosis显示文摘AIM:To determine if subclinical abnormal glucose tolerance(SAGT)has influence on survival of non-diabetic patients with liver cirrhosis.METHODS:In total,100 patients with compensatedliver cirrhosis and normal fasting plasma glucose were included.Fasting plasma insulin(FPI)levels were measured,and oral glucose tolerance test(OGTT)was performed.According to OGTT results two groups of patients were formed:those with normal glucose tolerance(NGT)and those with SAGT.Patients were followed every three months.The mean follow-up was932 d(range of 180-1925).Survival was analyzed by the Kaplan-Meyer method,and predictive factors of death were analyzed using the Cox proportional hazard regression model.RESULTS:Of the included patients,30 showed NGT and70 SAGT.Groups were significantly different only in age,INR,FPI and HOMA2-IR.Patients with SAGT showed lower 5-year cumulated survival than NGT patients(31.7%vs 71.6%,P=0.02).Differences in survival were significant only after 3 years of follow-up.SAGT,Child-Pugh B,and high Child-Pugh and Model for EndStage Liver Disease(MELD)scores were independent predictors of death.The causes of death in 90.3%of cases were due to complications related to liver disease.CONCLUSION:SAGT was associated with lower survival.SAGT,Child-Pugh B,and high Child-Pugh and MELD scores were independent negative predictors of survival. | Diego García-Compeán Joel Omar Jáquez-Quintana Fernando Javier Lavalle-González José Alberto González-González Linda Elsa Mu?oz-Espinosa Jesús Zacarías Villarreal-PérezEndocrinology Service and Department of Internal Medicine University Hospital 'Dr. José E.

| 4 | Relationship between alcohol consumption and clinical manifestation of patients with fatty liver:a single-center study显示文摘BACKGROUND:Fatty liver is a common chronic liver disease worldwide.It is associated with an increasing morbidity in China in recent years.The aim of this study was to analyze the effect of drinking alcohol on the hemoglobin and biochemical values of patients with fatty liver.METHODS:We investigated the clinical and laboratory data of 669 patients with fatty liver.Of the 669 patients,166 consumed alcohol more than 60 g per week for at least 2 years,and 503 did not have a history of long-term alcohol consumption.We further analyzed the relationship between alcohol consumption and clinical characteristics of these patients.RESULTS:The values of aspartate transaminase (AST),gammaglutamyl transpeptidase (GGT),and hemoglobin in the long-term consumption group were significantly higher than those in the non long-term consumption group (P<0.05).In the patients without long-term alcohol consumption,the values of GGT and hemoglobin in patients with light alcohol consumption were significantly higher than those in non alcohol consumers (P<0.05).CONCLUSION:Alcohol consumption is associated with significantly increased values of AST,GGT,and hemoglobin in patients with fatty liver,suggesting their potential roles in hepatic steatosis. | International Health Care Center (Wang XF) and Department of Gastroenterology (Yue M),First Affiliated Hospital,Zhejiang University School of Medicine,Hangzhou 310003,China | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 5 |
| 5 | An Internal State Variable Model for the Low Temperature Tempering of Low Alloy Steels显示文摘An internal state variable (ISV) framework is used to predict the rate and degree of strain relaxation associated with the stage I, low temperature tempering of martensite. A single variable tracks the change in volume between the tempered an untempered structures. The rate at which this occurs is taken to be a function of martensite fraction, temperature, degree of tempering, and carbon concentration. Experimental dilatometty data is used to both fit and validate the model. | Mark T. Lusk, Young-Kook Lee, Herng-Jeng Jou, William H.

| 6 | Survival factors after resection of small hepatocellular carcinoma显示文摘Early resection of hepatocellular carcinoma is a key measure to prolong the survival of patients. This study was designed to summarize our experience in surgical resection of small hepatocellular carcinoma (HCC), and to analyze the factors influencing the postoperative survival of patients. METHODS:The clinicopathologic data of 105 patients with small HCC after resection from 1986 through 2003 were analyzed ; the patients had been followed up for more than half a year (median 33 months). Nine clinicopathologic factors, preoperative α-fetoprotein (AFP) level, liver cirrhosis, Child-Pugh score, tumor size (>2cm vs.≤2 cm) and number (single vs. multiple), capsule formation, portal vein tumor thrombi (PVTT), Edmondson tumor grade and surgical method, were analyzed by the log-rank test and the Cox proportional harzards model analysis. RESULTS:The cumulative 1-,3- and 5-year survival rates after the operation were 86.5%, 70.3% and 55.2%, respectively, and the 1-, 3- and 5-year disease-free survival rates were 78%, 58. 9% and 45. 6%, respectively. One patient died from esophagogastric varices hemorrhage in 2 weeks after reoperation. Thirty-six patients had intrahepatic recurrence or metastasis postoperatively and 34 patients died. The Kaplan-Meier method and the Cox proportional harzards model analysis indicated that poor Child-Pugh score, tumor more than 2 cm in diameter, PVTT and multiple lesions (including satellitic lesions) were adverse factors affecting postoperative survival. The Cox proportional harzards model analysis indicated that tumor size, PVTT and multiple lesions were the factors influencing postoperative disease-free survival. CONCLUSIONS:Limited hepatectomy with a margin more than 1 cm is an appropriate surgical approach. Adverse preoperative Child-Pugh score and postoperative intrahepatic recurrences are the main factors leading to the death of patients with small HCC. | Departments of Surgical Oncology (Wu FS, Zhao WH, Ma ZM, Teng LS and Wang M) and General Surgery ( Liang TB and Zheng SS) , First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，3： | 5 |
