Objective To evaluate the factors of influence on the prognosis and survival rate in patients of primary hepatic cellular carcinoma(HCC) after interventional therapy.Methods 258 cases of HCC were treated with interventional therapy,the data of these cases and the survival rate were analysed.Results The prognosis in patients with HCC was relation to the hepatic function,therapeutic methods and accumulation of iodized oil by analysis of Cox Regression.The cumulative survival rate was different in HCC with different pathological type,different grade of hepatic function,with or without tumor embolus in portal vein,different cumulation of iodized oil and different therapetic methods,there was significance in statistics between most of them.Conclusion Cox Regression model can be used to analyse synthetically the factors that significantly affected the survival period in the patients with HCC.

Objective To investigate the clinical and CT manifestations of iatrogenic hepatic subcapsular biloma (HSB).Methods Seven cases with iatrogenic HSB confirmed by paracentesis in our hospital,and 18 reported in literatures were enrolled into this study.Their clinical and CT manifestations were retrospectively analyzed.Results Of the 25 cases,9 were secondary to laparoscopic cholecystectomy (LC),5 were secondary to percutaneous transhepatic choleductus drainage (PTCD),4 were secondary to percutaneous transhe-patic removal of bile duct stones,2 were secondary to open cholecystectomy,and 5 were secondary to other surgeries.CT showed localized or diffused hepatic subcapsular fluid collection with crescent-shaped or sac-shaped.The hepatic volume decreased and the surface was compressed in some of the cases with diffused fluid collection.Conclusion When localized or diffused hepatic subcapsular fluid collection was detected in CT imaging after liver or gallbladder surgeries (especially LC and PTCD),HSB should be considered.Paracentesis should be performed as soon as possible.

Objective To explore a reasonable,accuracy and effectual proposition model for medical imaging examination.Methods Mean scores and their standard deviation and distribution as well as the difficulty,discrimination,reliability and validity of the test paper were analyzed for the 2005 grade 7-year program students by using SPSS 13.0 statistic software.Results The scores of the 67 copies of test paper displayed a normal distribution,with the mean score of 73.76 and standard deviation of 11.88.The difficulty,reliability and validity indexes of the test paper were 0.74,0.78 and 0.25 respectively.The difficulty,discrimination,reliability and validity indexes of subjective items were higher than those of objective items(0.76 vs.0.73,0.94 vs.0.90,0.71 vs.0.68,0.32 vs.0.22,respectively).Conclusions We should keep quite high proportion of subjective items and make detailed scoring standard in medical imaging examination.Furthermore,as a supplement,objectively items such as multiple choice questions can expand the scope of knowledge examined.

Objective To investigate the changes of left ventricular structure and function in patients with liver cirrhosis and their correlation with the model for end-stage liver disease (MELD) score. Methods A total of 89 cirrhotic patients admitted between June, 2012 and June, 2014 and 30 healthy control subjects were enrolled in the study. According to MELD score, the cirrhotic patients were divided into 3 groups with MELD scores≤9, between 10 and 19, and≥20. The parameters of the left ventricle in resting state were measured using Doppler echocardiography, including left ventricular end systolic diameter (LVESD), left ventricular end diastolic diameter (LVEDD), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), left atrial diameter (LAD), ejection fraction (LVEF), cardiac output (CO), mitral flow velocity, and E wave deceleration time (DT), and evaluated their relationship with MELD score. Results Compared with the control subjects, the cirrhotic patients showed significantly increased LVESD, LVEDD, IVST, LAD, CO and DT but reduced VE/VA ratio (P<0.05 or 0.01). The values of LVESD, LVEDD, IVST, LAD and DT increased gradually with MELD scores (P<0.05 or 0.01). VE/VA ratio was higher in patients with MELD score of 10-19 than in those with MELD score≤9, and decreased significantly in those with MELD score≥20. Of the cirrhotic patients, 55%were found to have left atrial enlargement and 44%had a VE/VA ratio≤1;left atrial enlargement and a VE/VA ratio below 1 were more common in patients with a MELD score≥20 than in those with lower MELD scores. The LAD, LVEDD and DT were positively correlated with MELD scores (r=0.208, 0.319 and 0.197, respectively;P<0.05 or 0.01). Conclusion The patients with liver cirrhosis can have cardiac function deficiency manifested mainly by left ventricular diastolic dysfunction in positive correlation with the severity of liver disease.
