Objective: To evaluate the clinical effect of Xuanbai Chengqi tang therapeutic aspiration syndrome. Method: A randomized

controlled study methods

seting Xuanbai Chengqi tang group and the control group. Each group is divided into two subgroups of patients group mechanical ventilation (MV) and non-mechanical ventilation (NO-MV). Control group

the use of conventional Western medicine treatment;Xuanbai Chengqi tang group

on the basis of conventional Western medicine

Plus Xuanbai Chengqi tang orally. ① Observations content include:before treatment and after 5 days oxygenation index (PaO2/FiO2)

body temperature

white blood cell count

C-reactive protein (CRP) and so on. ② Therapeutic evaluation:after 2 weeks of treatment

patients were evaluated prognosis of lung injury. Result: ① After 5 days treatment

Xuanbai Chengqi tang group comparison control group between subgroups

Whether NO-MV or MV two subgroups oxygenation index

temperature difference was statistically significant (P<0.05) and but body temperature

white blood cell count

the two groups only in the NO-MV subgroups were significantly different (P<0.05). ② After 2 weeks of treatment

two groups patients were evaluated prognosis of lung injury

there are statistically significant difference in clinical effect (P<0.05). Conclusion: Based on the conventional Western medicine treatment

with the Prescription of Xuanbai Chengqi tang helps reduce the patient's lung damage

improve the therapeutic effect

its mechanism may reduce the systemic inflammatory response.
