针对多轴分布式电机驱动车辆电液复合制动中易出现的车辆制动抖动问题,提出了一种建压阶段电机制动力修正策略和一种基于前馈-反馈的协调控制策略,分别在建压阶段和其他阶段通过协调复合制动力来解决制动抖动的问题。针对防抱死控制系统与电机制动系统共同作用时的制动矛盾,提出了一种基于PID控制的ABS控制策略,主要通过改变电机制动力来解决制动矛盾的问题。通过TruckSim、Matlab/Simulink及AMESim联合仿真验证,制动冲击度在建压阶段下降了20.66%,在电机退出阶段下降了92.59%,驾驶感觉得到明显改善。而ABS控制策略也可在保证理想滑移率的同时完成制动能量回收;结合整车制动试验,表明协调控制策略在保证制动效果良好的同时实现了制动能量回收,效果显著。

目的分析跗骨窦综合征在关节镜下的特征,评价应用关节镜治疗的临床效果。方法回顾性分析2012年1月至2014年1月,本院收治的15例诊断为跗骨窦综合征的病例。其中男6例,女9例;平均33.4岁（19~48岁）。其中,踝扭伤后11例,跟骨骨折后2例,胫腓骨骨折后1例,强直性脊柱炎1例。均应用距下关节镜检并行镜下手术。术前后应用直观模拟量表（VAS）评估术后疼痛改善情况,应用美国骨科足踝外科（AOFAS）踝-后足评分评估恢复效果,并记录相关并发症。结果关节镜下发现11例患者有不同程度的滑膜充血增生、脂肪纤维化、疤痕形成,有3例患者伴距跟骨间韧带的局部撕裂,1例伴腓骨肌腱损伤,1例伴距跟关节面软骨损伤;有2例患者镜下未见明显异常。针对不同病变,行跗骨窦区的增生滑膜、疤痕及脂肪组织清除,射频电极止血。术后平均随访16个月（6~28个月）,疼痛消失及明显缓解者13例,2例缓解不明显,其中,诊断强直性脊柱炎1例患者缓解3月后再发疼痛,经抗炎治疗缓解。AOFAS踝-后足评分均较术前明显改善,疼痛症状明显缓解,平均VAS评分从术前的7.7分下降到2.1分,优良率86.7%（13/15）。结论跗骨窦综合征在关节镜下常有明确的滑膜充血或增生等病理表现,通过关节镜手术可取得较优良的疗效。

目的了解国家免疫规划(National Immunization Program,NIP)疫苗损耗现状。方法在中国东部、中部和西部地区选取8个省份21个县区的400家预防接种单位,收集2022年4种多剂次疫苗和7种单剂次疫苗的使用和接种剂次数,分析疫苗损耗系数、损耗原因和影响因素。结果调查预防接种单位NIP疫苗总损耗系数为1.25,其中多剂次疫苗、单剂次疫苗分别为2.04、1.02,各疫苗损耗系数范围分别为1.52-3.30、1.00-1.06。线性秩回归分析显示,预防接种单位级别、服务周期、设置多剂次疫苗专日接种、日平均接种量和接种人员数量是疫苗损耗的影响因素。疫苗打开后超过规定时间所致损耗占已开封疫苗损耗的97.54%;过效期报废所致损耗占未开封疫苗损耗的69.15%。结论调查地区预防接种单位多剂次疫苗损耗系数显著高于单剂次疫苗。需优化多剂次疫苗包装规格和预防接种服务模式,加强疫苗计划管理,提高疫苗使用效率。
