Background. Tianjiu
therapy has established efficacy against chronic
asthma with related symptoms or the medication need during
asthma attack. This study aimed to explore the optimal duration of Tianjiu
therapy for
asthma. Methods. This study was a self-comparison-to-the-baseline study, which comparing treatment with Tianjiu
therapy for 1 year and 2 years in the same 102 chronic
asthma patients. Totally 6 sessions of Tianjiu treatment were provided, 3 sessions in a year as a course of treatment and totally two years treatment. The primary endpoint was the number of
asthma related symptoms which frequently appeared in
asthma patients and the frequency of
bronchodilator used during
asthma attack. Results. The frequency of
bronchodilator used during
asthma attack significantly improved (χ (2) = 46.276, P = 0.000). But the number of
asthma related symptoms which frequently appeared in
asthma patients added by 1.38 points (95% CI, 0.25 to 2.51), 2.93 ± 0.41 in 1-year group and 4.31 ± 0.41 in the 2-years group (P < 0.05). Conclusions. The effect of 2 years Tianjiu
therapy was not as effective as 1 year such treatment for
asthma, but the second year Tianjiu
therapy was still needed because it has a role to consolidate the curative effect of Tianjiu
therapy for
asthma.
