During the past decade, feature extraction and knowledge acquisition based on video analysis have been extensively researched and tested on many applications such as closed-circuit television （CCTV） data analysis, large-scale public event control, and other daily security monitoring and surveillance operations with various degrees of success. However, since the actual video process is a multi-phased one and encompasses extensive theories and techniques ranging from fundamental image processing, computational geometry and graphics, and machine vision, to advanced artificial intelligence, pattern analysis, and even cognitive science, there are still many important problems to resolve before it can be widely applied. Among them, video event identification and detection are two prominent ones. Comparing with the most popular frame-to-frame processing mode of most of today＇s approaches and systems, this project reorganizes video data as a 3D volume structure that provides the hybrid spatial and temporal information in a unified space. This paper reports an innovative technique to transform original video frames to 3D volume structures denoted by spatial and temporal features. It then highlights the volume array structure in a so-called ＂pre-suspicion＂ mechanism for a later process. The focus of this report is the development of an effective and efficient voxel-based segmentation technique suitable to the volumetric nature of video events and ready for deployment in 3D clustering operations. The paper is concluded with a performance evaluation of the devised technique and discussion on the future work for accelerating the pre-processing of the original video data.

2-Amino-3-nitrile-chromenes with potential antitumor activity were constructed by a novel catalytic system. In combination with a-naphthol, quinine could effectively promote the Michael-cyclization process of malononitrile with functionalized chalcones in high yields and moderate to good enantioselectivity（up to 84% ee）. It is notable that the enantioselectivity could be greatly improved when a-naphthol was employed as additive.

AIM： To explore the expression of cadherin isoforms in cultured human gastric carcinoma cells and its regulation. METHODS： The expressions of cell adhesion molecules （including E-cadherin, N-cadherin, α-catenin, β-catenin） and cadherin transcription factors including snail, slug and twist were determined by reverse transcriptasepolymerase chain reaction（RT-PCR）, immunoblotting and immunofluorescence in SV40-immortalized human gastric cell line Ges-1 and human gastric cancer cell lines MGC-803, BGC-823 and SGC-7901. RESULTS： All cell lines expressed N-cadherin, but not E-cadherin. N-cadherin immunofluorescence was detected at cell membranous adherents junctions where co-localization with immunofluorescent staining of inner surface adhesion proteins α- and β-catenins was observed. The transformed Ges-1 and gastric cancer cell lines all expressed transcription factors （snail, slug and twist） which inhibited the expression of E-cadherin and triggered epithelial-mesenchymal transformation. CONCLUSION： Cadherin isoforms can change from E-cadherin to N-cadherin in transformed human gastric cancer cells, which is associated with intracellular events of stomach carcinogenesis and high expression of corresponding transcription factors.

Dynamic detection based on optics sensors and ranging radars is a new method to detect the luminous intensity of flight aid lights. The optics sensors can get the illumination information of each light, the ranging radar gets the distance information, and then data amalgamation technology is used to compute the luminous intensity of each light. A method to modify the errors of this dynamic detection system is presented. It avoids the accumulation error and measurement carrier’s excursion error by using peak value detection based on optics sensors to estimate the accurate position of each light, then to modify the lights’ lengthways distance information and transverse position information. The performance of the detection and ranging system is validated by some experiments and shown in pictures.

Background No-reflow is associated with an adverse outcome and higher mortality in patients with ST-segment elevation acute myocardial infarction （STEMI） who undergo percutaneous coronary intervention （PCI） and is considered a dynamic process characterized by multiple pathogenetic components. The aim of this study was to investigate the effectiveness of a combination therapy for the prevention of no-reflow in patient with acute myocardial infarction （AMI） undergoing primary PCI. Methods A total of 621 patients with STEMI who underwent emergency primary PCI were enrolled in this study. Patients with high risk of no-reflow （no-flow score 〉 10, by using a no-flow risk prediction model, n = 216） were randomly divided into a controlled group （n = 108） and a combination therapy group （n = 108）. Patients in the controlled group received conventional treatment, while patients in combination therapy group received high-dose （80 mg） atorvastatin pre-treatment, intracoronary administration of adenosine （140 ~tg/min per kilogram） during PCI procedure, platelet membrane glycoprotein lib/Ilia receptor antagonist （tirofiban, ***/kg bolus followed by 0.15 ~tg/kg per minute） and thrombus aspiration. Myocardial contrast echocardiography was performed to assess the myocardial perfusion 72 h after PCI. Major adverse cardiac events （MACE） were followed up for six months. Results Incidence of no-reflow in combination therapy group was 2.8%, which was similar to that in low risk group 2.7% and was significantly lower than that in control group （35.2%, P 〈 0.01）. The myocardial perfusion （A= 13） values were higher in combination therapy group than that in control group 72 h after PCI. After 6 months, there were six （6.3%） MACE events （one death, two non-fatal MIs and three revasculafizations） in combination therapy group and 12 （13.2%）（four deaths, three non-fatal MIs and five revascularizations, P 〈 0.05） in control group. Conclusions Combination of thrombus aspiration, high-dose stat
