Results: After one course of treatment, the effect in Group A and Group B was obviously better than that in Group C and Group D (P0.01), while Group C and Group D had also significant difference (P0.01). Contents of plasma ET in all groups were significantly decreased. The decrease degree was Group B, A, C and D in order. Contents of serum ACE in Group C, A and B had significant difference compared with those before treatment (P0.01, P0.05). Contents of serum ACE in all groups were significantly increased.
