Objective To assess the various features of Budd-Chiari syndrome(BCS)on three- dimensional contrast-enhanced magnetic resonance angiography(3D CE MRA)and to evaluate the potential value of this new technique.Methods Thirty-three patients with BCS underwent 3D CE MRA examination. In 23 cases,BCS was secondary to hepatocellular carcinoma(21 patients)or right adrenal carcinoma (1 patient)or thrombophlebitis(1 patient).Ten patients had primary BCS.The patency of the hepatic veins,inferior vena cava(IVC)and portal veins were assessed.The presence of intra-and extrahepatic collaterals,liver parenchymal abnormalities and porto-systemic varices were evaluated.The diagnosis on 3D CE MRA was correlated with that on inferior vena cavography and right hepatic venography,which were available in 10 and 2 cases respectively.Results Various features of BCS were displayed on 3D CE MRA. Hepatic venous findings included tumor thrombosis(19 patients),tumor compression(2 patients), nonvisualization(4 patients)and focal stenosis(4 patients)of the hepatic veins.IVC findings were severe stenosis or occlusion(10 cases),tumor direct invasion(2 cases),tumor thrombosis(3 cases), thrombophlebitis(1 case)and web formation(3 cases).Intrahepatic collaterals were demonstrated in 9 patients including 2 with "spider web" sign.Detected extrahepatic collaterals included dilated azygos and hemiazygos veins(13 cases)and left renal-inferior phrenic-pericardiophrenic collaterals(2 cases).The occlusion of the left portal vein and the presence of porto-systemic varices were depicted in 2 and 10 patients respectively.Liver parenchymal abnormalities identified by 3D CE MRA consisted of caudate lobe enlargement(7 cases),heterogenous enhancement(18 cases)and associated tumors(18 cases). Compared with inferior vena cavography and hepatic venography,the accuracy of 3D CE MRA in the diagnosis of IVC obstruction or hepatic venous stenosis was 100%.Conclusion 3D CE MRA can display various features of BCS and has the potential to provide an accurate diagnosis.

To study the effect of miR-490 on Coxsackievirus B3 (CVB3) replication, HeLa cells were trans- fected with miR-490 in vitro, and infected with a Renilla luciferase (RLuc)-expressing CVB3 variant (RLuc-CVB3). The activities of RLuc in these cells were measured at 8h intervals from 0 to 40 h post-infection (p.i.), and the effects of miR-490 on RLuc-CVB3 replication were observed. In a further study, HeLa cells were transfected with either miR-490 or antisense miR-490 (AMO-miR-490), and were then infected with an enhanced green fluorescence protein (EGFP)-expressing CVB3 variant (EGFP-CVB3). The replication of EGFP-CVB3 was then determined by detecting the expression of EGFP. We observed that miR-490 could significantly inhibit the expression of RLuc in infected cells at 32 h p. i. Furthermore, in HeLa cells infected with EGFP-CVB3 at 32 h p.i., EGFP expression was also significantly inhibited by the presence of mniR-490. The inhibitory effect of miR-490 on EGFP expression in EGFP-CVB3-infected cells could be reversed by tranfection with AMQ-miR-490. These results indicated that miR-490 significantly inhibits the replication and expression of QVB3.

The genes of maltooligosyl trehalose synthase (MTSase) and maltooligosyl trehalose tetrahydrolase(MTHase) from Sulfolobus solfataricus ATCC 35092 were amplified using PCR. The expression plasmids, pTrc99a-MTSase and pTrc99a-MTHase, were constructed by inserting these two DNA fragments into E. coli expression vector pTrc99a. The specific activity of MTSase and MTHase in E. coli BL21(DE3) at optimal fermentation conditions reached 31.3U/g (wet cell) and 403U/g (wet cell), respectively. The biotransformation of partially hydrolyzed starch to trehalose catalyzed by MTSase and MTHase was carried out at 75℃ and pH 5.0. The highest yield of trehalose (ca. 53.6%) was gained when the original starch concentration was 15%(w/v) and the DE value was 10.

OBJECTIVETo investigate the protective effect and action mechanism of petroleum ether extracts from Saussurea involucrate on brain tissues of hypoxia rats under constant pressure and closed conditions.
METHODThe PESI dosage-dependent experiment for hypoxia rats was conducted under constant pressure and closed conditions by intraperitoneally injecting 125, 250, 500 mg x kg(-1) to finalize that the optimum dosage is the high dose of PESI. Afterwards, 90 Wistar rats were randomly divided into the hypoxic model group, the acetazolamide 250 mg x kg(-1) group and the PESI high dose group. Each group was further divided into three subgroups according to different hypoxia times, with 10 rats in each subgroup. Under the same hypoxia and administration conditions, the rats were sacrificed after 0, 3, 6 h respectively. Their brain samples were collected for common pathological observation and immunohistochemical staining of HIF-1alpha. Real-time RT-PCR was used to detect HIF-1alpha, EPO, HO-1 and Caspase-3 gene expressions. And the Western blot assay was adopted to detect HIF-1alpha protein expression.
RESULTThe brain tissues of the hypoxia model group were severely damaged with the increase in the hypoxia time. The acetazolamide group and the PESI high does group were damaged in a much lower degree. According to the gene expression and the Western blot assay, high dose of PESI could inhibit HIF-1alpha expression. According to the pure gene expression test, high dose of PESI could increase EPO and HO-1 mRNA expressions, but inhibit Caspase-3 mRNA expression.
CONCLUSIONPESI's protective mechanism for brain tissues of hypoxia rats under constant pressure and closed conditions may be related to its effects in inhibiting HIF-1alpha expression, increasing EPO expression and resisting cell apoptosis.

A method of comprehensive chemical pattern recognition of Atractylodis Rhizoma was established by GC-MS fingerprint, principal component analysis, cluster analysis and discriminant analysis. A DB-wax column (0.25 mm x 60 m, 0.25 microm) with El ion source and 70 V electron multiplier were used for GC-MS analysis. Using principal component analysis, cluster analysis, and discriminant analysis, 15 common peaks of sample fingerprints for chemical pattern recognition research were analysed. The same results were obtained from the fingerprint, principal component analysis and cluster analysis, which could use to distinguish genuine Atractylodes lancea, ungenuine A. lancea and A. chinensis. Thus, this method could be used for the quality control and comprehensive evaluation of Atractylodis Rhizoma.
