摘要：为了寻找结构新颖、抗癌活性显著的先导化合物,以桦木醇为原料,设计并合成了一系列桦木醇-28-吲哚酯衍生物,并对合成产物进行了抗增殖活性测试、靶点预测和分子对接研究。结果表明,所有衍生物对3种癌细胞的抑制作用均优于桦木醇。其中,桦木醇-28-((6-氟)吲哚-3-)乙酸酯对3种癌细胞均表现出了低微摩尔级别的抗增殖活性(IC 50<10.00μmol/L),其对A549细胞的作用最强(IC 50=7.25μmol/L),是桦木醇的4.15倍。作用机制研究表明,上述化合物可能通过抑制PI3K-Akt通路发挥抗癌作用。总之,该化合物是一种具有良好抗癌活性的先导化合物,对其进一步的结构修饰和药理研究具有重要的意义。

摘要：为深入探究专业滑雪运动员与大众滑雪爱好者对功能性滑雪内衣的差异化需求,基于功能性滑雪内衣认知情况、现有滑雪内衣穿着感受、滑雪运动体验及滑雪内衣功能需求4个维度设计调查问卷,应用交叉分析和卡方检验等方法对234份有效问卷进行分析。结果表明:与专业滑雪运动员相比,大众滑雪者对滑雪内衣认知程度较低,其热湿舒适性是影响穿着感受的首要因素;2组人群对滑雪内衣的保暖透气、吸湿排汗及拉伸弹性功能需求较高,而对不同身体部位的功能需求呈现一定差异。研究结果为滑雪内衣的功能性分区设计及相关企业进行产品商业化开发提供参考,对研发符合我国参加国内外重大体育竞赛运动员生理特征的高性能滑雪内衣具有指导意义。

摘要：管廊作为常见的城市基础设施,其安全性对于城市居民极其重要。该研究针对现阶段管廊监测系统效率低、成本高的问题,提出了一种基于计算机视觉技术的高效沉降监测方法。该方法创新性地使用特征平面叠加的方法,采用基于组合缩放因子的空间监测方案,利用不同的像素精度及灵活的截面叠加实现实时沉降监测。以北京市慈云寺桥地下管廊为例对该方法进行验证。实验结果显示:随着监测距离的增加,监测误差能够收敛于特定常数值,该方法可以通过校准的方式实现有效的高精度、高性能监测。环境因素定量监测结果也显示,即使大部分监测截面处在不同温湿度、气压、粉尘的影响下,该方法的监测结果仍具有较高的稳定性。
