[Experimental study on the treatment of hypertension with combined traditional Chinese and Western medicine].

Abstract

In order to study the connection of diastolic activity of smooth muscles of blood vessels with development of hypertension, plasma cAMP, cGMP, TXB2, 6-K-PGF1 alpha, ANP, SP were determined with radioimmunoassay, of 173 hypertension patients with Liver Yang exuberance (LYE) 91 cases, and Yin deficiency and Yang exuberance (YDYE) 82 cases. In addition, 228 health subjects served as control. The results showed that the levels of cAMP, cGMP and TXB2 in both LYE and YDYE groups were higher than those in the control group, but the levels of ANP, SP and cAMP/cGMP ratio in LYE and YDYE groups were lower than those in the control. As to the level of 6-K-PGF1 alpha, no significant variance was found between these groups. After TCM-WM treatment, the levels of cAMP, cGMP and TXB2 in LYE and YDYE groups got down, as compared with those in the control, adversely the levels of ANP, SP and 6-K-PGF1 alpha in LYE and YDYE groups turned up significantly. However the cAMP/cGMP ratio had no remarkable change between these groups. The linear regression analyses between the diastolic pressure and ANP or SP both proved negative correlation (r = -0.36, P less than 0.05; r = -0.35, P less than 0.05). The findings indicated that the TCM-WM treatment was the most effective among the therapies employed in the study, and that this therapy affected the diastolic activity of smooth muscles by modulating the above factors existing in the nervous and endocrine systems of the patients with hypertension.
