大脑肿瘤分割对于医师判断肿瘤恶化程度非常重要。然而,由于肿瘤的不规则形状、与周围组织的低对比度以及出现位置的不固定,给脑肿瘤的精确分割带来很大的困难。传统的K-means分割方法仅仅利用图像的灰度特征,很难准确分割肿瘤边界。利用灰度共生矩阵提取出的纹理特征,并结合图像几何不变矩特征对分割出的脑肿瘤图像进行特征提取。灰度共生矩阵定义为像素对的联合概率分布,是一个对称矩阵,它不仅反映图像灰度在相邻的方向、相邻间隔、变化幅度的综合信息,也反映了相同的灰度级像素之间的位置分布特征,是计算纹理特征的基础;几何矩(不变矩)具有旋转、平移、尺度等特性,能将图像分解为有限特征值,并且通过对比所提取出的同一病人的肿瘤图像的不变矩参数,可以获得该肿瘤几何形状变化程度。实验结果表明,该方法可以同时从纹理和几何特征对图像特征进行描述,与分别采用灰度共生矩阵和不变矩方法进行特征提取相比较,降低了算法计算量,同时提升了算法的抗噪性。

认知功能障碍是各种原因导致的认知功能损害,严重影响患者的生活质量。高龄、既往心脑血管疾病、麻醉及手术等均是其危险因素。细胞自噬是维持细胞能量稳态必需的细胞内降解途径,与应激、感染、癌症及神经退行性疾病等密切相关。近年来大量研究表明,细胞自噬在认知功能障碍机制中发挥重要作用。神经元内自噬水平异常会破坏细胞稳态,严重时可影响患者的认知功能。通过调控各种细胞自噬信号通路可明显改善细胞缺氧、促进能量及物质代谢,改善认知功能,以上为临床认知功能障碍的预防和治疗提供了新的思路。

Objective： To explore the effects of aerosolized ketamine on the level of nitric oxide and nitric oxide synthetase in the lung tissue in rat asthma model. Methods： Forty SD rats were randomly assigned to five groups： control group （group N）, asthma model group （group A）, two pretreated groups of different concentrations of ketamine （group K1, K2） and dexamethasone group（group D） with eight rats in each group. The rats in group A were sensitized by injection of ovalbumin （OA） together with aluminum hydroxide and bordetella pertussis as adjuvants. Two weeks after the sensitization, aerosolized OA was used to cause asthma. The rats in group K1 and K2 were sensitized with OA as group A , and then exposed to aerosol of ketamine , with the concentration of 25 g/L and 50 g/L respectively. Before using aerosolized OA,the rats in group D were exposed to aerosol of 0.01% dexamethasone .The level of NO2^-/NO3^- in lung tissues, inducible nitric oxide synthetase（iNOS） and constitute nitric oxide synthetase（cNOS） was measured in all groups. Results： The level of NO2^-/NO3^- and the activity of iNOS in lung tissues in group A were signiticantly higher than those in the other groups. The iNOS activity and the level of NO2^-/NO3 ^- in lung tissues were highly positively correlated. Conclusion： NO can induce airway hyperreactivity that may worsen asthma. Aerosolized ketamine can decrease the iNOS expression and reduce the level of NO in the lung tissue in rat asthma model.
