However it is not a true and independent gold standard. We described a new TDI validation method by using a specially developed left ventricular balloon model mounted in a water bath and constructed using two pear-shaped balloons. It was connected to a pulsatile flow pump at 8 stroke volumes (50-85 ml/beat). The displacement and velocity of the balloon walls were recorded simultaneously by video imaging and TDI on a GE-Vingmed System Five with a 5 MHz phased array probe at the highest frame rates available. Conventional M-mode and 2-D imaging verified that our balloon model mimicked the shape and wall motion of left ventricle. There was a good correlation and agreement between the maximum video excursion of the anterior and posterior walls of the phantom and the results of the temporal integration of digital distance data by TDI (Anterior wall: r = 0.97, SEE = 0.24 mm, mean +/- s = 0.04 +/- 0.24 mm; Posterior wall: r = 0.95, SEE = 0.22 mm, mean +/- s = 0.03 +/- 0.24 mm). Analysis of the velocity profile by the TDI method showed that the velocity at each measured point was correlated well with the velocity obtained from the video images (Anterior wall: r = 0.97, SEE = 0.30 mm, mean +/- s = -0.04 +/- 0.28 mm; Posterior wall: r = 0.97, SEE = 0.30 mm, mean +/- s = 0.04 +/- 0.28 mm). Our balloon model provided a new independent method for the validation of TDI data. This study demonstrated that the present TDI system is reliable for measuring wall motion distance and velocity.","PeriodicalId":73995,"journal":{"name":"Journal of Tongji Medical University = Tong ji yi ke da xue xue bao","volume":"21 4","pages":"337-40"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9170499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) method. Serum soluble Fas (sFas) levels in 28 cases of LC and 27 cases of HCC were measured by enzyme-linked immunosorbent assay (ELISA) method. Compared with LC, apoptotic indices (AI) in HCC tissues were significantly reduced (P < 0.001), expression of Fas was decreased (P < 0.05), and that of FasL was increased (P < 0.05). Serum sFas levels in HCC patients were significantly higher than those in normal controls. Down-regulation of Fas expression, up-regulation of FasL expression in hepatocytes and elevation of sFas level in serum might contribute to tumor escape from immune surveillance of the body.

In these models, two-site ELISA and RT-PCR were applied to determine the level of IL-4 protein and mRNA expression in spleens respectively, clone forming units (CFUs) of infected kidneys were determined with the plating dilution method, and mean survival time (MST) of the mice was recorded. The results showed that, when compared with the controls, protein level of IL-4 increased in both intact mice infected with lethal doses of yeast (day 3, P < 0.05; day 7, P < 0.001) and immunosuppressed mice infected with sublethal doses of yeast (day 3, P > 0.05; day 7, P < 0.05). Furthermore, the level of IL-4 was higher on day 7 than on day 3 after infection (P < 0.001 and P < 0.05 respectively in two groups). The tendency of IL-4 mRNA expression was similar with that of IL-4 protein. As for fungal loads in kidneys, CFUs were significantly higher on day 7 than on day 3 after infection (P < 0.001 in both groups). Mice in both groups succumbed to infection within several days. It was suggested that IL-4 might play a promoting role in the development of murine systemic Candidiasis.","PeriodicalId":73995,"journal":{"name":"Journal of Tongji Medical University = Tong ji yi ke da xue xue bao","volume":"21 2","pages":"168-70"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10020018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
