Objective: To observe the effect of Tanreqing injection in treatment of lung infection after thoracic operation.Method: Eiighty cases of lung infection after thoracic operation were randomly divided into the observation group

the control group with 40 cases in each group.The two groups underwent routine operation therapy

postoperative broad-spectrum antibiotic for prevention control of infection.At the same time with ambroxol hydrochloride injection 30 mL+250 mL saline

gtt

daily.Based on the treatment of control group the observation group was given Tanreqing injection 30 mL+250 mL saline

gtt daily.Two groups of patients were treateol for 7 days as a 1 course

the therapeutic effects were observed after 1 course of treatment.Result: The cure rate was 77.50% and 62.50% in the observation group and the control group

with significant difference（P<0.05）;the total efficiency was 95% and 82.50% in the observation group and the control group with significant difference（P<0.05）.Vanishing time of sputum

（3.68±1.15）

（5.27±1.24）

（4.68±1.08）

（12.62±3.28） d

and in the control group respectively（7.68±1.72）

（5.43±1.22）

（7.36±1.55）

（7.83±1.35）

（15.15±3.18） d

the observation group was beffer than in control group（P<0.05）.Conclusion: The operation clinical curative effect of Tanreqing injection in treatment of lung infection after thoracic is remarkable.It can shorten the durations of sputum
