Nitric oxide (NO), an important biologi-cal messenger and effective factor, has been proved to offercardioprotective benefits through the followings: a) modu-late blood vessel tone, blood pressure, and velocity ofblood flowing through organs; b) prevent leukocyte fromadhering to endothelium; c) inhibit proliferation and mi-gration of vascular smooth muscle cells; d) decrease per-meability of vessel; e) modulate contractility of myocardi-um; f) inhibit platelet aggregation and adhesion, thus slowprocedure of atherosclerosis. Most premenopause womenare less vulnerable to coronary artery disease (CAD),while postmenopause women have high risk of CAD, it wasbelieved that the reason was cardioprotection diminishedbecause of endogenous estrogen insufficient. Coronaryevents can be significantly decreased after estrogen re-placement treatment in postmenopause women with CAD.Cardioprotection from estrogen may be obtained throughmodulating function of endothelium and smooth musclecells by increasing release of NO.

一氧化氮(NO)是重要的生物信息分子和效应分子,在心血管系统可①调节血管张力、血压、器官血流量;②抑制白细胞粘附于内皮;③抑制平滑肌细胞增殖、迁移;④降低血管通透性;⑤影响心肌收缩性;⑥抑制血小板聚集和粘附,阻滞动脉粥样硬化的发生、发展,从而达到心血管保护作用。大部分绝经前女性较少患冠脉病变,但停经后冠脉病变迅速增加,这种保护作用的丧失是由于内源性雌激素的缺乏。绝经后妇女采用雌激素替代治疗后冠脉事件明显减少。雌激素可能通过NO直接调节血管内皮及平滑肌功能,达到心血管保护作用。

Objectives: The comparison of the tendency and accuracy of artery blood pressure was made between tonometry, oscillometric and invasive technique Methods: The systolic, mean and diastolic blood pressure values for the tonometry and oscillometric on same pectoral limb, the invasive on dorsalis pedis were record at 2 min intervals during general anestheisa in 40 cases, scheduled for elective upper abdominal surgery Results: The correlation were...

Objectives: The comparison of the tendency and accuracy of artery blood pressure was made between tonometry, oscillometric and invasive technique Methods: The systolic, mean and diastolic blood pressure values for the tonometry and oscillometric on same pectoral limb, the invasive on dorsalis pedis were record at 2 min intervals during general anestheisa in 40 cases, scheduled for elective upper abdominal surgery Results: The correlation were good between tonometry oscillometric and invasive technique The tendency of the systolic, mean and diastolic blood pressure change between three methods were similar basically The peak value is smaller and the peak occurs delay in tonometry technique when the blood pressure changes markedly in a short time Conclusion: The tendency and accuracy of tonometry technique were good in common use The technique may be limited in critical care situations

目的 :研究张力血压 (TBP)测量法的临床应用特点及对血压变化的反应速度和准确性。方法 :40例择期行上腹部手术患者全麻下经足背动脉行IBP监测 ,同侧上肢行TBP和NIBP监测 ,每间隔 2min同步记录IBP、NIBP和TBP的SBP、MAP和DBP值 ,每例患者均记录 2 0对数据。结果 :IBP和TBP、IBP和NIBP、TBP和TBP之间的SBP ,MAP和DBP均具有良好的相关性 ,其中以NIBP和TBP的相关性最好 (SBP :r=0 98,MAP :r=0 96 ,DBP :r=0 97)。三种测量方法的SBP、MAP和DBP的变化趋势一致。血压出现急剧变化时 ,与IBP相比 ,TBP波峰滞后出现 ,峰值偏低。结论 :TBP测量法能较准确地反映患者的无创血压水平 ,能连续和实时地反映患者的动脉血压状况及变化趋势 ,但当血压发生急剧和 (或 )异常波动时需注意其应用的局限性。
