结果表明，应用波生坦后，尽管收缩期和舒张期血压没有变化，收缩末期和舒张期心室体积比例明显升高。

Peak systolic and diastolic strain rates also increased significantly after bosentan treatment, the results indicate, although systolic and diastolic blood pressures were not affected.

结果：咀嚼5分钟和10分钟后的收缩期峰流速、舒张期末峰流速及平均峰流速均高于咀嚼前，有显著性差异（P<0.05）。

Result: The mean glow velocity, velocity of flow during systole and diastole was shown to increase significantly 5, 10 minutes after mastication (P< 0.05).

收缩期峰值流速餐前和餐后各时点比较差异有统计学意义（P<0.01），餐后各时点比较差异无统计学意义（P>0.05）；

Significant difference was found between fasting PSV value and postprandial values(P<0.01), but no difference was found among values at various postprandial time points(P>0.05).
