目的:观察三生调脂舒(丸剂)对原发性高血压患者动态动脉硬化指数(AASI)的影响。方法:67例患者随机分为两组。对照组(33例)应用西药控制血压,试验组(34例)在对照组基础上加用三生调脂舒(丸剂)治疗3个月,治疗前后通过24 h动态血压(24 h AB...目的:观察三生调脂舒(丸剂)对原发性高血压患者动态动脉硬化指数(AASI)的影响。方法:67例患者随机分为两组。对照组(33例)应用西药控制血压,试验组(34例)在对照组基础上加用三生调脂舒(丸剂)治疗3个月,治疗前后通过24 h动态血压(24 h ABPM)监测血压,分析血压参数,计算AASI。结果:(1)两组治疗前后24 h、白昼血压对比无明显差异,但试验组夜间血压较对照组有改善(P<0.05),考虑两组夜间血压的差异主要是受到昼夜节律改善的影响。(2)与对照组相比,治疗组使用三生调脂舒(丸剂)后动态动脉硬化指数降低(P<0.05)。结论:三生调脂舒(丸剂)能够降低原发性高血压患者的动态动脉硬化指数,对动脉硬化有改善作用。展开更多

The active average sound intensity (AASI) detector can estimate all azimuths of users with the same frequency band at the same time in order to achieve directional communication by vector combination. Space-division multiple access (SDMA) based on TRM combined with the AASI detector is proposed in this paper, which can make the capacity of the code division multiple access (CDMA) UWA system significantly increase. The simulation and lake test results show that the 7-user UWA multi-user system can achieve low bit error communication.展开更多
