Fifteen patients undergoing hysteromyomectomy with 0 75% bupivacaine epidural anesthesia were studied to observe the alterations of the levels of plasma atral natriuretic peptide, renin activity, angistensin Ⅱ and aldosterone systems.

研究了15例子宫肌瘤切除术患者应用0.75％布比卡因硬膜外麻醉血浆心钠素和肾素活性、血管紧张素Ⅱ－醛固酮系统的变化及相互调控。结果表明，血浆ANP水平在麻醉10min后各时点明显低于麻醉前（P＜0.05），PRA在麻醉10min后亦明显低于麻醉前（P＜0.01），而AⅡ和AL无显著改变（P＞0.05）。

Objective To study the effects of angiotensin Ⅱ receptor antagonist valsartan on intrarenal mRNA expressions of ETA and ETB in diabetic rats.

Venous blood was drawn from 35 old hypertension patients when blood pressure was nomial and abnormal, respectively. Epinephrine. norepinephine, endothelins, angiotensin Ⅱ and calcitonin-gene-related peptide were determined by radio-immunity. The above five cytokines were also determined in 33 old healthy people. The cytokines levels were compared between the normal and abnormal blond pressure in hypertension patients and also between the old hypertension patients and healthy persons. The correlation between blood pressure and cytokines were analyzed.

35例老年EH患者，血压正常时和血压波动时各抽取静脉血一次，放射免疫法检测肾上腺素、去甲肾上腺素、内皮素、血管紧张素Ⅱ和降钙素基因相关肽水平，同时检测33例健康老年人群各因子水平，比较EH患者血压波动前后各因子水平的差异和血压正常范围时两组人群各因子水平差异，分析不同状态下血压和各因子水平之间的相关性。

Cardiac hypertrophy and extracellular matrix remodeling happened as a result of chronic overrange of pressure in heart and hypervolaemia which lead to damage of relaxation and compliance of heart.Drugs including renin-angiotensin converting enzyme inhibitor,angiotensin receptor blocker,aderergic receptor blocker,aldrosteron antagonism,tatins endothelin receptor blocker pancreatic kiniogenase and calcalium channel blocker,can delay or reverse the remodeling by several mechanisms.
