ObjectiveTo investigate application value of parametric image processing in contrastenhanced ultrasound imaging in diagnosis of ovarian masses. MethodsFifty cases with ovarian masses underwent routine ultrasound and contrast-enhanced ultrasound imaging using a new dedicated parametric image processing software SonoLiver to analyze patterns of vascular formation and blood stream perfusion in the ovarian mass tissues on a digital video recorder in real time, compare their morphological characteristics of time-intensity curve (TIC) and dynamic vascular patterns (DVP) curve, and analyze quantitatively all indicators generated by SonoLiver.ResultsIn ultrasound imaging of the 50 cases, there were 24 cases (86%) displaying mainly blue lowly-enhanced imaging in those with benign masses and 15 cases (68%)displaying mainly red highly-enhanced imaging in those with malignant masses, with statistical significance (P <0. 01 ). There was significantly different characteristics of TIC and DVP between patients with benign and malignant masses. In 23 cases with benign masses, their DVP were significantly higher above the baseline than in those with malignant ones ( P = 0. 000), and in 15 cases with malignant lesions, their DVP were much shorter below the baseline than in those with benign ones, with statistical significance (P <0.05). The intensity of contrast medium, the time to reach its peak intensity and average transit time were all significantly higher in those with malignant masses than in those with benign ones (all P < 0. 05 ). But, no statistical difference in the time of initial increasing between the two groups was found (P > 0. 05). ConclusionsThere is significant difference in TIC and DVP of ultrasound imaging between benign and malignant masses, which if combined with contrast enhanced ultrasound parametric image processing can provide a more visualized quantitative information of benign and malignant ovarian masses with SonoLiver software.

OBJECTIVETo explore the inhibitory effect of cinnamaldehyde on invasion capacities of human breast cancer cell line MDA-MB-435S and its relation with regulating the expression of miR-27a.
METHODSThe effect of cinnamaldehyde on invasive capacities of MDA-MB-435S was measured by Transwell matrigel invasion assay. The effect of miR-27a expression on invasive capabilities of MDA-MB-435S, the intervention of cinnamaldehyde in the miR-27a expression, and its relation with its effect on invasive capabilities were defected with liposome 2000 transinfection miRNA27a mimics/inhibitors, real time-polymerase chain reaction (Real-time PCR), and Transwell chamber model.
RESULTSCompared with the control group, the number of cells passing through the transwell chamber was more significantly reduced after treated by cinnamaldehyde for 12 h (P < 0.05). The miR-27a expression was 962.07 times and 40% of that of the control group after transinfected by miR-27a mimics and miR-27a inhibitors. After transinfected by miR-27a inhibitors, the number of cells passing through the transwell chamber was more significantly reduced (P < 0.05). The miR-27a expression of MDA-MB-435S was down-regulated by 12-h treatment of cinnamaldehyde (2(-deltaCt) = 0.56, 0.18, 0.18, respectively). The number of miR-27a mimics transinfection pretreated MDA-MB-435S cells passing through the transwell chamber increased more obviously than the number of un-pretreated MDA-MB-435S cells in the control group (P < 0.05).
CONCLUSIONSCinnamaldehyde could inhibit invasive capabilities of human breast cancer cell line MDA-MB-435S. The over-expression of miR-27a played an important role in the invasive capability of MDA-MB-435S. The inhibition of cinnamaldehyde on invasive capabilities of MDA-MB-435S cells was correlated with down-regulating the expression of miR-27a.

In order to remove the artifacts of peripheral digital subtraction angiography (DSA), an affine transformation-based automatic image registration algorithm is introduced here. The whole process is described as follows: First, rectangle feature templates are constructed with their centers of the extracted Harris corners in the mask, and motion vectors of the central feature points are estimated using template matching technology with the similarity measure of maximum histogram energy. And then the optimal parameters of the affine transformation are calculated with the matrix singular value decomposition (SVD) method. Finally, bilinear intensity interpolation is taken to the mask according to the specific affine transformation. More than 30 peripheral DSA registrations are performed with the presented algorithm, and as the result, moving artifacts of the images are removed with sub-pixel precision, and the time consumption is less enough to satisfy the clinical requirements. Experimental results show the efficiency and robustness of the algorithm.
