DOI:
Objective: To investigate the change of global and regional left ventricular systolic function after aspiration thrombectomy in percutaneous coronary intervention(PCI) or single PCI for patients with acute myocardial infarction by real-time three-dimensional echocardiography(RT-3DE). Methods: Fifty-five subjects with acute myocardial infarction were studied by RT-3DE. And they were divided into two groups with aspiration thrombectomy or without PCI. Then respectively compared the global and regional diastolic volumes(EDV, rEDV), the global and systolic volumes(ESV, rESV), the global and ejections fractions(EF, rEF) between the two groups after 1 week and 6 months of PCI, and observed the thrombolysis in myocardial infarction trial(TIMI) and ST segment resolution of electrocardiogram(STR). Results: Compared with single PCI, TIMI grade 3 and STR≥50% was better in patients with aspiration thrombectomy. And the EDV, rEDV, ESV, rESV by RT-3DE of patients with single PCI at the six months were larger than that with aspiration thrombectomy in PCI(P<0.05), while EF, rEF was lower(P<0.05). And the △EDV, △EF of all the patients at the six months had positive correlation with STR. Conclusion: Aspiration thrombectomy in PCI with AMI were more conductive to recover of the left ventricular function by RT-3DE. And △EDV, △EF by RT-3DE and STR can predict clinical prognosis more accurately for AMI with PCI.

Objective: To evaluate the carotid elasticity in patients with coronary heart disease(CHD) by two-dimensional strain imaging. Methods: Two hundred and six hospitaized patients with suspected CHD who were to undergo coronary angiography were enrolled in the research. According to the coronary angiography, the patients were divided into one diseased branch group inculding sixty-three cases, multiple diseased branch group including one hundred and three cases and non-CHD group including thirty cases. All patients were examined by M mode echocardiogram and two-dimensional strain imaging respectively, the measurement results were recorded. All clinical datas were statistically analyzed and processed. Results: ① The systolic peak global CS and early systolic global CSr in multiple diseased branch group were lower than those in one diseased branch group and those in non-CHD group(P<0.01), while the late systolic global CSr and β2 in multiple diseased branch group were greater than those in one diseased branch group and those in non-CHD group(P<0.01), the systolic peak global CS and early systolic global CSr in one diseased branch group were lower than those in non-CHD group(P<0.01), while the late systolic global CSr and β2 in one diseased branch group were greater than those in non-CHD group(P<0.01). ②The ROC curve analysis indicated that the under-curve areas of the systolic peak global CS, the early systolic global CSr, the late systolic global CSr and β2 were 86.9%, 82.7%, 80.3% and 91.4% respectively. All of them showed high diagnostic value to CHD(P<0.001). ③The discriminant function “Y=0.817β2+0.500IMT-0.185plaque(1 or 0)” was obtained by discriminant ananlysis and its sensitivity and specificity of diagnosis of CHD were 78.4% and 93.3% respectively, the accuracy rate was 80.6%. Conclusion: The elasticity of blood vessel wall in CHD patients changed earlier than morphological changes and related with the degree of stenosis of coronary artery. CS and CSr which were carotid elasticity indexes may become two of the noninvasive indexes in evaluating CHD.

DOI:
Objective: To evaluate the clinical prognosis and survival outcomes of hepatocellular carcinoma(HCC) patients with portal vein tumor thrombosis(PVTT). And to compare survival rate between groups of synchronous and asynchronous PVTT. Methods: A prognostic model was developed for 57 HCC patients with PVTT treated with transcatheter arterial chemoembolization(TACE) from 2007 January to 2013 March. Local tumor response was evaluated by modified response evaluation criteria in solid tumor. Clinical characteristics, prognosis, and patient survival were analyzed by the life table method, the Kaplan-Meier method and Cox’s proportional hazards model. Results: According to mRECIST, complete response, partial response, stable disease and progressive disease were found in 1 patient(1.5%), 14 patients(24.5%), 20 patients(35.5%) and 22 patients(38.5%), respectively. The 6-, 12-, 18- and 24-month overall survivals for the HCC patients with PVTT after TACE were 50.8%, 29.8%, 24.6% and 10.5%, respectively. The median survival was 6.8 months. In the multivariate analysis, pre-treatment prognostic factors for overall survival were AST, CHE, APS, complete portal vein occlusion and local tumor response. Conclusion: There are many factors affecting the survival outcomes of HCC patients with PVTT, and there is no difference in survival analysis study between synchronous and asynchronous portal vein tumor thrombosis.

CHANG Na;GUO Qi-yong;YU Bing;MA Yue;REN Ying
DOI:
Objective: To evaluate the usefulness of coefficient variance(CV) of apparent diffusion coefficient(ADC) value in differentiating pancreatic carcinoma from focal pancreatitis. Methods: Diffusion weighted MR data were obtained from 28 patients of pancreatic carcinoma and 7 patients of focal pancreatitis. The mean value(x) and standard deviation(s) of ADC value in every lesion were measured. The CV of the lesion was defined as CV＝s/x. The x values and CVs were compared between groups using Student’s t test. Result: The mean value of pancreatic carcinoma was 1.46±0.29, and the mean value of focal pancreatitis was 1.58±0.28. There were no obvious differences between the mean value of pancreatic carcinoma and focal pancreatitis(t=1.02, P=0.32). CV of pancreatic carcinoma was 0.16±0.06, and CV of focal pancreatitis was 0.10±0.04. CV of pancreatic carcinoma was significantly higher than that of focal pancreatitis(t=2.44, P=0.02). Conclusion: The CVs of ADC values in lesions were more useful than that of mean value to distinguish pancreatic carcinoma and focal pancreatitis.
