Dynamic Effect of Rolling Massage on Blood Flow

The Chinese traditional medical massage has been used as a natural therapy to eliminate some diseases. Here, the effect of the rolling massage frequency to the blood flow in the blood vessels under the rolling massage manipulation is studied by the lattice Boltzmann simulation. The simulation results show that when the frequency is smaller than or comparable to the pulsatile frequency of the blood flow, the effect on the blood flux by the rolling massage is small. 011 the contrast, if the frequency is twice or more times of the pulsatile frequency of the blood flow, the blood flux is greatly enhanced and increases linearly with respect to the frequency. Similar behavior has also been observed on the shear stress on the blood vessel walls. The result is helpful for understanding that the rolling massage has the function of promoting the blood circulation and removing the blood stasis.     

基于负荷心肌声学造影评价八段锦在冠脉介入术后的康复价值

急性心肌梗死（AMI）是心血管疾病最常见的致死原因，AMI患者行经皮冠状动脉介入术（PCI）后需进行心脏康复。八段锦是中国传统的健身功法。以PCI术后患者为研究对象，利用负荷心肌声学造影（MCE）等手段，旨在评价八段锦对AMI患者预后心肌血液灌注、运动功能及生活质量的影响，指标包括心肌血流量（MBF）、室壁运动异常率、六分钟步行试验（6MWT）距离、Croog生活质量评分等。结果显示，与单纯PCI相比，使用八段锦作为康复方案术后1年时的心内膜下MBF、6MWT距离、睡眠与性功能、自觉健康状况、情绪、日常生活子项评分均显著增高，室壁运动异常率显著降低。说明八段锦可显著提高AMI患者的心肌血液灌注和改善心室壁运动，提高心肺运动功能，不但可改善预后的躯体健康和日常生活能力，还具有调节情绪和改善睡眠的作用。
