Objective To evaluate sound velocity tissue quantification ( SVQ ) for the quantitative assessment of liver fibrosis stage in chronic hepatitis B ,and to evaluate the correlation between diagnostic performance of sound velocity tissue quantification and blood parameters . Methods From the May of 2013 to May of 2014 ,collect ninety‐nine patients with chronic hepatitis B who was diagnosed by clinic and / or liver biopsy as experiment group ,and thirty healthy volunteers as control group at the same time . The experiment group and control group were evaluated with to measurement the zone speed index ( ZSI) ,and blood cell count . The AST/PLT ratio index ( APRI) was calculated according the following formula , APRI=AST(ULN)/PLT(109/L) . The liver biopsy was performed in the same day with SVQ and all blood parameters .ZSI and APRI were compared by correlation with liver fibrosis stage in chronic hepatitis B . Referring to the histologic fibrosis stage on liver biopsy ,all the ZSI and the APRI value were assessed by using ROC curve analysis . The corresponding cut‐off value ,sensitivity and specificity were also calculated andcompared.Results 1)ThemeanvaluesofAPRIwere(15.9±5.7)m/sforpatientswithS0,(28.1± 2 .8)m/s for patients with S1 ,(35 .8 ± 1 .2)m/s for patients with S2 ,(42 .6 ± 0 .8)m/s for patients with S3 , and (46 .3 ± 1 .3)m/s for patients with S4 .2)Accordingly ,the areas under the ROC curve for ZSI and APRI were 0 .875 and 0 .762 for S≥S1 ,0 .832 and 0 .597 for S≥S2 ,0 .913 and 0 .675 for S≥S3 ,0 .891 and 0 .709 for S≥S4 ,respectively . Conclusions The ZSI and APRI all could be used to evaluate the stage of liver fibrosis ,but the ZSI index is superior to APRI in assessing the stage of liver fibrosis . SVQ could provide object and accurate image ,the quantitative analysis of tissue could timely and accurately evaluate the severity of liver fibrosis .

Objective To study the relationship of microinflammation,nutrition and common carotid artery intima-media thickness(CCA-IMT) for the early prevention and interference of ischemic stroke. Methods(CCA-IMT was) measured by carotid arterial ultrasound in 250 elderly subjects.The levels of serum high-sensitivity C-(reactive) protein(hsCRP),ferritin,albumin,pre-albumin and transferrin were assayed at the same time.According to the results of CCA-IMT,all the subjects were divided into five groups:

Objective To investigate the performance of dual source CT scanning combined with low-tube-voltage iterative reconstruction (SAFIRE) for demonstrating coronary artery calcium plaques. Methods 70 patients with clinically suspected coronary atherosclerosis and with normal BMI received SAFIRE-3 or filtered back projection (FBP) for reconstruction after undergoing CT scans with tube voltage range of 100 kV. The CT images (average CT values, noise, SNR, and CNR) and subjective scores (number of calcium plaque, calcium plaque adjacent artifacts, and image quality) were compared between the two groups. Results The average CT value of the aortic root did not differ significantly between the two procedures for reconstruction (P > 0.05). Ob jective evaluation of the images (noise, SNR, and CNR) between the two groups was statistically significant (P < 0.05 for all comparisons), so was image subjective rating (number of calcium plaque and rate of calcium plaque edge)(P < 0.05 for all comparisons). SAFIRE-3 reconstruction was markedly superior to FBP reconstruc-tion. Conclusions Low kilovoltage combined with reconstruction of SAFIRE-3 can reduce calcium plaque adja-cent artifacts and enhance quality of images , which is better than FBP in displaying the morphology and adjacent conditions of calcified plaque; therefore it is worth popularizing.

ObjectiveTo evaluate the value of 24 h dynamic electrocardiogram (DCG) and treadmill exercise testing(TET) in diagnosing coronary heart disease(CHD),and analyze relevant index between coronary arteriography(CAG) and treadmill exercise testing.MethodsOne hundred and forty-nine borderline cases of coronary heart disease were enrolled.Every patient was examined by DCG,TET,and CAG,compared the diagnostic value of TET combined with DCG and TET or DCG alone,and record the increased heart rate during the first minute( △ HRl min) of TET and systolic blood pressure(SBP) recovery.The patients were divided into a CHD group and a non-CHD group according to the results of coronary angiography.ResultsThe sensitivity rate was 78.57％ and specific rate was 70.77％ by means of TET.The sensitivity rate was 61.90％ and specific rate was 66.15％ by means of DCG.The sensitivity rate was 95.23％ ,specific rate was 55.38％,positive predictive value was 73.39％ and negative predictive value was 90.00％ by parallel way of DCG and TET,its sensitivity rate (95.23％) and negative predictive value (90.00％ ) were more than those of DCG or TET alone.The sensitivity rate was 52.38％,specific rate was 95.38％,positive predictive value was 93.62％ and negative predictive value was 60.78％ by serial way of DCG and TET,its specific rate (95.38％) and positive predictive value (93.62％ ) were more than those of DCG or TET alone.The number of men in the CHD group was higher than the number of women.Ratio of systolic blood pressure recovery(rSBPR) in the CHD group was significantly higher than that in the non-CHD group ( P ＜ 0.01 ).Conclusion It can obviously enhance the sensitivity rate and specific rate if combined TET with DCG.Patients with CHD have a delayed decline in SBP during recovery which can be one of the indexes to estimate the extent of myocardial ischemia and coronary artery lesion.

Objective To observe the effects of green fluorescence protein mediated by lentivirus in bladder, and to de?termine the amount of virus obtained good transfection effects. Methods lentivirus carring GFP gene was perfused using transurethral approach into bladder of guinea pigs. Samples of bladder, liver, kidney and lungs were collected for frozen sec?tions after feeding seven days. The distribution of green fluorescence was observed using laser confocal microscopy. Re?sults The titer of lentivirus was 4 × 108. GFP was found under the mucosa when the amount of lentivirus transurethral was 30μL. GFP was distributed widely in muscle layer using 40μL lentivirus. GFP was detected even stronger in muscle layer when the amount was 50μL. GFP was found in muscle layer when 25μL lentivirus was injected intravenously. GFP was not found in other tissues than in bladder via transurethral perfusion. There was higher GFP in liver, lungs and other organs than in bladder via intravenous injection. Conclusion Lentivirus can mediate GFP transfecting bladder of guinea pig successful?ly and escape the distribution of GFP all over the body intravenously, which will bring new research direction and method for clinical treatment of diseases in bladder.
