Abstract：Background Atherosclerotic plaque rupture is the primary mechanism of thrombosis which plays a key role in the onset of acute coronary syndromes. Detection of these plaques prone to rupture （vulnerable plaque） could be clinically significant for prevention of cardiac events. It has been shown that high metabolism cells have a high uptake of fluorine-18 fluorodeoxyglucose （18F-FDG）. The objective of this study was to investigate the correlation of FDG uptake and the immuno-histochemistry parameters of plaques, and the effect of atorvastatin on vulnerable atherosclerotic plaque in a rabbit *** Ten male New Zealand White rabbits were divided into three groups as follows：（1） normal control group （n=2,C group）： the animals were fed a standard diet at 120 g/d and were given water ad labium; （2） atherosclerosis group （n=4,As group）： animals were fed with high fat diet for 5 months after aortic endothelia damage; （3） treatment group （atherosclerosis ＋ atorvastatin, n=4, Statin group）： animals were fed with high fat diet for 5 months and then changed into normal chow plus atorvastatin （2.5 mg·d-1·kg-1） treatment for another 4 months. Then these four rabbits were imaged with fluorine-18 fluorodexyglucose positron emission tomography/computed tomography （PET/CT） and sacrificed for pathohistologic studies. FDG uptake by the aorta was expressed as target-to-background ratio （TBR）. Maximal standardized uptake value （SUV） was measured over the thoracic and abdominal aortas. The aortic smooth muscle cell （SMC） number, CD-14 antibody positive cell （macrophage） number and the ratio of the thickness of fibrous cap to the thickness of lipid core （cap-to-core ratio） in atherosclerotic plaques were *** As group showed significantly higher uptake of FDG than C group （SUVs： 0.746±0.172 vs. 0.286±0.073, P 〈0.001）. After 4 months of atorvastatin treatment and the modification of diet, SUVs decreased significantly （Statin group：0.550±0.134, compared to As grou

评估冠状动脉危险性通常是利用预测心血管危险因素的弗雷明汉危险积分。颈动脉超声检测颈动脉内中膜厚度(C IMT)可被用来评估冠状动脉粥样硬化的存在。检测C IMT可以修正通过弗雷明汉危险积分评估的冠状动脉危险性。多数临床试验证实C IMT可以作为动脉粥样硬化病变的预测因子。该文综述C IMT相关文献,明确C IMT在筛选冠心病中的价值,C IMT对中等危险的人群重新评价意义重大。对60岁以上的飞行员来说,超声检测C IMT可作为常规检查。

主成分分析(PCA)是模式识别领域一种重要的方法,现在已被广泛地应用于人脸识别算法中,但基于PCA人脸识别系在应用中面临着一个重要障碍:增量学习问题。针对这个问题,提出了一种适用于成批增量数据的IPCA算法,该算法在原始P分解的基础上,利用空间投影变换,使得可以在一个低维空间求解整体PCA,从而降低了求解的复杂度,在此基础上对该增量算进行了核化,并在ORL人脸数据库上验证了算法的有效性。
