慢性阻塞性肺疾病(COPD)病理学基础是气道对不同有害颗粒和气体刺激引发的异常炎症反应。吸烟是COPD最主要的诱发因素,但其发病机制目前仍不明确,且缺乏有效的防治手段。糖皮质激素作为最常用的临床抗炎药物,对COPD炎症的治疗却没有理想的效果。最近的研究表明由新型的辅助性T细胞17(Th17)介导的中性粒细胞性气道炎症可能是COPD激素抵抗的重要原因。在COPD发病过程中,Th17与中性粒细胞的产生可能由氧化应激、组蛋白去乙酰化酶和炎症小体等共同调控。针对这些信号通路的新型靶向治疗药物和方案有望给COPD的治疗带来新希望。

Deep forest is a tree-based deep model made up of non-differentiable modules that are trained without backpropagation. Despite the fact that deep forests have achieved considerable success in a variety of tasks, feature concatenation, as the ingredient for forest representation learning, still lacks theoretical understanding. In this paper, we aim to understand the influence of feature concatenation on predictive performance. To enable such theoretical studies, we present the first mathematical formula of feature concatenation based on the two-stage structure, which regards the splits along new features and raw features as a region selector and a region classifier respectively. Furthermore, we prove a region-based generalization bound for feature concatenation,which reveals the trade-off between Rademacher complexities of the two-stage structure and the fraction of instances that are correctly classified in the selected *** a consequence, we show that compared with the prediction-based feature concatenation(PFC), the advantage of interaction-based feature concatenation(IFC) is that it obtains more abundant regions through distributed representation and alleviates the overfitting risk in local regions. Experiments confirm the correctness of our theoretical results.

用免疫组织化学的方法,研究了大鼠胎脑中家蚕神经系统特异蛋白(Bombyrin)的分布以及与神经干细胞的关系.结果表明,家蚕Bombyrin类似物主要分布在大鼠胎脑的脑室下区、纹状体等区域,特别是表达在大鼠的神经干细胞中,而分化的神经干细胞则没有Bombyrin类似物的免疫活性.Western blot的分析表明,大鼠脑中存在77 kDa和110 kDa 2种Bombyrin类似的蛋白.这些结果暗示,大鼠脑中Bombyrin类似蛋白可能与神经干细胞特性的维持有关.
