The effects of angiotensin II receptor antagonist losartan on elastic properties of aorta in patients with mild to moderate essential hypertension were assessed. The ascending aortic distensibility in 26 patients (48 +/- 3 years) with mild to moderate essential hypertension before and after 12 weeks of treatment with losartan (50 mg/day) was evaluated by using two-dimensional echocardiography. M-mode measurements of aortic systolic (Ds) and diastolic diameter (Dd) were taken at a level approximately 3 cm above the aortic valve. Simultaneously, cuff brachial artery systolic (SBP) and diastolic (DBP) pressures were measured. Aortic pressure-strain elastic modulus (Ep) was calculated as Dd x (SBP-DBP)/(Ds-Dd) x 1333 and stiffness index beta (beta) was defined as Dd x Ln (SBP/DBP)/(Ds-Dd). Blood pressure significantly decreased from 148 +/- 13/95 +/- 9 mmHg to 138 +/- 12/88 +/- 8 mmHg (systolic blood pressure, P = 0.001; diastolic blood pressure, P = 0.003). There was no significant difference in pulse pressure before and after treatment with losartan (53 +/- 10 mmHg vs 50 +/- 7 mmHg). The distensibility of ascending aorta increased significantly as showed by the significant decrease in pressure-strain elastic modulus from 4.42 +/- 5.79 x 10(6) dynes/cm2 to 1.99 +/- 1.49 x 10(6) dynes/cm2 (P = 0.02) and stiffness index beta from 27.4 +/- 32.9 to 13.3 +/- 9.9 (P = 0.02). Although there was a weak correlation between the percent changes in pressure-strain elastic modulus and stiffness index beta and that in diastolic blood pressure after losartan treatment (r = 0.40, P = 0.04 and r = 0.55, P = 0.004, respectively), no correlation was found between the percent changes in pressure-strain elastic modulus and stiffness index beta and that in systolic blood pressure (r = 0.04, P = 0.8 and r = 0.24, P = 0.2, respectively). Our study demonstrated that angiotensin II receptor antagonist losartan has a beneficial effect on aortic distensibility in patients with mild to moderate essential hypertension and this effect is partly independent of blood pressure reduction.

Renalase, a novel amine oxidase, is secreted by kidney. It regulates heart function and blood pressure by degrading catecholamines. Hormones secreted by the kidney are associated with cardiovascular disease. Renalase, as a new biomarker of heart and kidney functional correlation, can lower blood pressure, protect ischemic heart muscle, improve heart function and degrade catecholamine.

OBJECTIVETo observe the clinical effects of acupuncture method of "Huoxue Sanfeng, Shugan Jianpi" (activating blood and eliminating wind, soothing liver and strengthening spleen) on morning blood pressure in patients with cerebral infraction combined with essential hypertension.

METHODSSixty-eight patients were randomly divided into an observation group and a control group, 34 cases in each one. The patients in the two groups were treated with acupuncture method of "Xingnao Kaiqiao" (consciousness-restoring resuscitation) and oral administration of nifedipine. In addition, patients in the observation group were treated with acupuncture method of "Huoxue Sanfeng, Shugan Jianpi" that met the criteria of standard manipulation, in which bilateral Renying (ST 9), Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3) were selected. The treatment was given once a day, five times a week, for totally six weeks. The improvement and control rate of morning blood pressure in the two groups were observed.

RESULTS(1) After treatment, the morning blood pressures were decreased significantly in the two groups (all P < 0.05); after 15 treatments, the reduction of systolic pressure and diastolic pressure in the observation group was superior to that in the control group, but the difference was not significant (both P > 0.05); after 30 treatments, the reduction of systolic pressure and diastolic pressure in the observation group was significantly superior to that in the control group (both P < 0.05). (2) After 30 treatments, the control rate of morning blood pressure in the observation group was significantly higher than that in the control group [82.4% (28/34) vs 58.8% (20/34), P < 0.05].

CONCLUSIONAcupuncture method of "Huoxue Sanfeng, Shugan Jianpi", characterized with standard manipulation criteria, can effectively control morning blood pressure in patients with cerebral infraction combined with essential hypertension.
