Objective　To evaluate the value of gradient-echo chemical shift imaging in detection of lipid-containing abdominal lesions. Methods　35 patients with abdominal lesions were divided into 2 groups according to whether or not they contained lipid. Breath-hold in-phase(IP) and opposed-phase(OP) acquisitions were performed. The demonstration of these lesions on IP and OP was compared. The signal intensity of these lesions on both images was measured. The percentage of signal intensity variation on IP and OP was calculated and statistically analyzed with non-parametric method between the 2 groups. Results　For lesions containing lipid, the signal intensity dropped significantly from IP to OP, with median value of signal intensity variation attaining 37.1%. On the other hand, for lesions not containing lipid, the signal intensity did not change obviously between IP and OP, whose median value of signal intensity variation was 3.3%. The difference between the 2 groups was statistically significant (u=4.56，P<0.01). Conclusion　Gradient-echo chemical shift imaging is an easy and practical way, helpful to detection of lipid component within abdominal lesions.

Objective To evaluate the usefulness of three dimensional dynamic contrast enhanced magnetic resonance angiography(3D DCE MRA) in the diagnosis of vena caval abnormalities. Methods 3D DCE MRA was performed on fifty two patients with suspected vena caval anomaly, thrombosis, stenosis, occlusion, or compression. Image quality and the presence of venous abnormalities and collaterals were evaluated. Comparison with conventional venacavography( n =15) and surgical findings( n =18) was made. Results 3D DCE MRA images were of diagnostic quality without artifact for all 52 patients. 3D DCE MRA clearly showed vascular anatomy, anomaly and various disorders. The site, extent, cause of venous obstruction, and collateral pathways were well depicted. According to venography or surgery, the sensitivity and specificity of 3D DCE MRA in the diagnosis of abnormalities of vena cava were both 100%. In addition, it had advantages regarding demonstration of extravascular lesions and multiplanar capabilities. Conclusion 3D DCE MRA is simple to perform and accurate in detecting various vena caval abnormalities.

Objective:To investigate the effect of microgroove surfaces of titanium on the adhesion and cell cycle progression of human gingival fibroblasts(HGFs).Methods:Microgroove titanium surfaces were fabricated on silicon plate by photolithography with parallel grooves:1 5,30 and 60 μm in width and 5 μm and 1 0 μm in depth,the groups were denoted as T1 5 /5,T1 5 /1 0,T30 /5,T30 /1 0, T60 /5 and T60 /1 0,respectively.Smooth titanium surfaces (T0)were used as the controls.Surface topography were observed by ES-EM.HGFs were cultured on the microgroove surfaces.Morphology of “contact guidance”was observed by immunofluorescence tech-nique.Cell cycle distribution was analyzed by Flow cytometry.Results:HGFs on the microgroove surfaces had “contact guidance”par-allel to the microgrooves,whereas the cells on T0 were oriented randomly.T60 /1 0 group had the highest percentage of S phase cells, followed by T30 group and T1 5 group,but still higher than that in the control group.In groups with higher groove width (T60 group and T30 group),the increase of groove depth benefited the increase of S phase percentage,while in T1 5 group,the increase of groove width decreased the S phase percentage.Conclusion:Surfaces of microgrooves with different dimensions achieved “contact guidance”for the cultured HGFs.The surfaces with increasing groove width and depth benefit the cell cycle progression.

The effects of hepatocyte growth factor(HGF) on the secretion of vascular endothelial growth factor(VEGF) in cultured bovine coronary artery endothelial cells(BCAEC), bovine coronary artery smooth muscle cells(BCASMC) and mouse cardiomyocytes were observed in vitro . The concentrations of VEGF in BCAEC control and HGF group at 12h were 10.51?2.90pg/ml and 9.31?2.78pg/ml, respectively. The concentrations of VEGF at 12h in BCASMC control and HGF group were 3.35 and 3.93 times of that at 3h respectively, the concentration of VEGF at 3h and 12h in BCASMC HGF group was 2.06 and 2.42 times respectively, of that in control group. The concentrations of VEGF at 12h in cardiomyocyte control and HGF group were 5.43 and 4.09 times, respectively, of that at 3h, and the concentrations of VEGF at 3h and 12h in cardiomyocyte HGF group was 2.74 and 2.06 times, respectively, of that in control group. These results indicated that BCAEC, BCASMC and mouse cardiomyocytes could secrete VEGF, and HGF could promote VEGF secretion in BCASMC and cardiomyocytes, but not in BCAEC.
