Objective: To observe the effect of modified Chenping Tang for the treatment of senile community acquired pneumonia with the syndrome of phlegm dampness obstructing lung and blood stasis.Method: A total of 104 patients were randomly divided into treatment group and control group by random number table

with 52 cases in each group. Patients in treatment group received routine western medicine combined with modified Chenping decoction

while patients in control group only received pure western medicine. Clinical symptom and sign scores

curative effect of traditional Chinese medicine (TCM) syndrome

peripheral blood inflammatory markers (white blood cell count

neutrophil count

rapid C reactive protein

erythrocyte sedimentation rate and procalcitonin)

inflammatory absorption of chest CT and adverse drug reactions were evaluated and compared.Result: Compared with control group

treatment group showed better clinical symptom and sign scores

curative effect of TCM syndrome

peripheral blood inflammatory markers

and inflammatory absorption of the chest CT among patients with senile community acquired pneumonia with the syndrome of phlegm dampness obstructing lung and blood stasis (P<0.01). Mild adverse reactions

such as phlebitis

gastrointestinal reaction and liver damage occurred in a few patients in the process of trial

but the adverse reaction rates between two groups were not statistically significant.Conclusion: Modified Chenping Tang combined with routine western medicine shows a better efficacy in treating patients with senile community acquired pneumonia with the syndrome of phlegm dampness obstructing lung and blood stasis

and so is worth clinical promotion and application.
