Abstract

Objective: To observe the clinical effect of Pingchuan oral liquid, including Hanchuan oral liquid (HCOL) and Rechuan oral liquid (RCOL), and to explore its mechanism.

Methods: HCOL and RCOL were prepared based on the therapeutic principles of eliminate phlegm, remove blood stasis, lower reversed Qi flow and relieve asthma. HCOL was used to treat 50 patients of bronchial asthma in Group A and RCOL for 55 patients in Group B, and they were compared with 52 patients treated with Guilong Kechuanning capsule in the control group. The relevant animal experiment was also conducted.

Results: The total effective rate of HCOL was 88.0%, that of RCOL was 90.9%, they were significantly higher than that of the control (73.1%, P < 0.05). Moreover, the two new preparations showed the effects in easing main symptoms and signs of asthma, decreasing peripheral eosinophilic granulocyte count and immunoglobulin level, and improving pulmonary function superior to those of Guilong Kechuanning capsule (P < 0.05, P < 0.01). Experimental study showed that they could lower blood thromboxane B2 and endothelin, raise blood nitric oxide and 6-keto-prostaglandin F1 alpha.

Conclusion: Pingchuan oral liquid is obviously effective in treating bronchial asthma, the mechanism possibly lays on adjusting immune function, anti-allergy and antagonizing inflammatory media.
