Objective: to observe the clinical efficacy of drug for promoting blood circulation and removing stasis in the early stage of pulmonary diseases'inflammation(that is, syndrome of turbid phlegm obstructing lung), and explore its mechanism of action.Methods: according to the principle of random and control, to divide the 60 patients complying with the standard of this research into two groups: 30 people in experimental group and 30 in control group. Treat the experimental group with Chinese medicines on the basis of conventional therapy with western medicine, using intravenous drip once a day. Meanwhile, treat the control group with western medicine only in conventional therapy. To observe the clinical general therapheutic effect, the death amount, the time to reach the objective effect, the syndrome effects, the hematology index before and after the cure and the untoward effects of all patients, and find out the result is: patients of two groups have no significant difference in clinical general therapheutic effect and death amount(p>0.05). But on the time to reach to the objective effect, experimental group(p<0.01) is significantly short than control group. And in the equal period of cure, experimental group's syndrome effects of (p<0.01) and hematology index are all better than control group.Conclusion: drug for promoting blood circulation and removing stasis should be applied into the early stage of inflammation, which can noticeably improve patients'clinical efficacy and control the reaction degree of inflammation. To combine western medicines with Chinese medicines together into disease cure can promote clinical effectiveness and shorten time of treatment. The mechanism of the above phenomenon may lie in the remakable healing efficacy of drug for promoting blood circulation and removing stasis on enhancing immunity, resisting oxidation, clearing inflammatory factor, protecting vascular endothelial cells, improving the microcirculation and and supplying oxygen and so on.
