心包積液時呼吸對血流動力學及室間隔運動的影響用超聲心動圖觀察心包積液伴有或不伴有心包填塞患者川例的血流動力學改變及室間隔隨呼吸運動倩況，計算rvi值，並與正常人進行對照。 -
Results the number of myocardial and brain and opioid receptors significantly increased, and they were significantly associated with the decreased hemodynamic parameters such as mean arterial pressure ( map ), left intraventricular systolic pressure ( lvsp ), the maximal rate of the change of intraventricular pressure ( dp / dtmax ) and the area of p - dp / dt vector loop ( lo )
結果創傷失血性休克后，大鼠心臟和腦和阿片受體數目明顯升高，親和力無明顯變化，心臟和腦的和阿片受體數目升高與創傷失血性休克后大鼠血流動力學指標下降呈顯著負相關。 -
The hemodynamic change induced by embolization of the cerebral arteriovenous malformation was analyzed using the water hammer principle. the highest pressure that can be reached when the water hammer phenomenon occurs was calculated. the acute instantaneous pressure rising may be an important factor leading to intracranial hemorrhage or swelling when the avm is embolized. it is shown that long feeding artery of avm will increase the possibility of direct water hammer, and high wall shear stress of feeding artery will increase the water hammer pressure. this suggests that such kind of avms should be embolized stepwise and the systemic pressure should be rationally reduced before embolization
以水擊原理分析了腦avm栓塞治療時血液動力學變化過程，計算了瞬時水擊壓力可能達到的最高值。瞬時增高的水擊壓力可能是avm栓塞時發生急性腦出血或腦腫脹的重要血液動力學因素。而avm供血動脈血管壁面切應力偏高和供血動脈過長可增加水擊的危險程度，提示對這類結構avm栓塞治療時應採取合理的降壓措施並盡可能分多次栓塞。
