目的探讨有氧运动康复对冠状动脉慢性闭塞(CTO)患者经皮冠脉介入治疗(PCI)术后心肺功能的影响。方法选择2019年1月至2021年12月于十堰市太和医院心血管诊疗中心连续纳入经冠状动脉(冠脉)造影明确诊断为CTO并成功行PCI的患者43例,随机分为常规组(n=22)和运动康复组(n=21)。常规组予以冠状动脉粥样硬化性心脏病(冠心病)规范药物治疗、健康教育;运动康复组在常规组治疗基础上予以固定踏车运动训练,无氧阈强度,30~40 min/次,5~7次/周。两组分别于术后1周、6月时行心肺运动试验,比较最大摄氧量(VO_(2)max)、最大公斤摄氧量(VO_(2)max/kg)、代谢当量(METs)、二氧化碳通气当量斜率(VE/VCO_(2)slope)、分钟自主通气量(VE)、做功效率(VO_(2)/WR)、氧脉(VO_(2)/HR)、峰值心率(HRPeak)和无氧阈时公斤摄氧量(AT)的变化情况。结果两组受试者基线时VO_(2)max、VO_(2)max/kg、METs、VE/VCO_(2)slope、VE、VO_(2)/WR、VO_(2)/HR、HRpeak和AT差异均无统计学意义(P>0.05);与基线时比较,常规组上述指标在6月时无明显变化(P>0.05),而运动康复组在6月时VO_(2)max、VO_(2)max/kg、METs、VE、VO_(2)/WR、VO_(2)/HR、HRpeak和AT较基线均有显著改善(P0.05)。结论有氧运动训练可有效改善CTO患者PCI术后的心肺功能,是CTO患者PCI术后的一种安全、有效的心脏康复方案。

现有方法存在着网络流量数据不平衡、检测准确率不足和误报率上升等问题。该文提出了一种基于改进的CBAM(Convolutional Block Attention Module)、膨胀卷积和BiGRU(双向门控循环单元)的网络入侵检测模型,旨在解决现有方法存在的问题。具体来说,为了应对数据分布不平衡的问题,采用了ADASYN(自适应过采样)算法进行自适应过采样,以平衡数据集。为解决检测准确率不足和误报率上升的问题,在特征提取阶段,首先引入了三层膨胀卷积,拓展感受野范围,从而全面地捕捉网络流量的特征。其次,采用改进的CBAM模块增强膨胀卷积对高级特征的提取能力。最后,引入BiGRU用于更深入捕捉特征之间的长期依赖关系,进一步提升模型的性能。实验结果表明,在NSL-KDD数据集上,该方法相对于其他方法具有更高的准确率(99.51%)和更低的误检率(2.90%),这表明该模型在网络入侵检测任务中是一种可行有效的方法。

针对超大采高液压支架试验台垂直加载液压缸同步控制问题,提出一种基于模糊进程标识符(PID)相邻交叉耦合同步控制策略,利用Creo-Adams及ANSYS建立液压支架试验台刚柔耦合动力学仿真模型,根据垂直加载实际工况添加约束条件。利用AMEsim及Matlab/Simulink建立垂直加载液压系统控制模型,基于各软件之间的接口技术构建Adams-AMEsim-Simulink机液控一体化的试验台多领域协同仿真模型。仿真得到模糊PID和常规PID下相邻交叉耦合同步控制策略的加载液压缸位移跟踪曲线、负载变化曲线、信号控制曲线、同步误差曲线。研究结果表明,相比于常规PID算法,模糊PID算法下的系统具有响应速度更快、控制精度更高等特点,使液压支架垂直加载四缸同步精度误差小于0.1 mm,满足使用要求。研究结论为液压支架试验台垂直外加载系统设计提供参考。
