Objective: To observe the clinical efficacy of Maxin Shigan Tang combined with Tingli Dazao Xiefei Tang as modified auxiliary therapy for community acquired pneumonia (CAP) in middle-aged and old patients as well as its effect on C-reactive protein (CRP)

erythrocyte sedimentation rate (ESR) and procalcitonin (PCT). Method: One hundred and six cases patients with CAP were divided into control group (52 cases) and experimental group (54 cases) by random number table. Patients in control group received cefoperazone sodium and sulbactam sodium for intravenous infusion

3 g

2 times/day and azithromycin injection for intravenous infusion

0.5 g

1 time/day

with a treatment course of 14 days in total. Based on the treatment of control group

patients in experimental group added Maxin Shigan Tang combined with Tingli Dazao Xiefei Tang

1 dose/day

with a treatment course of 14 days. Before and after treatment

scores of main symptoms and signs were recorded;fevers

cough

expectoration

lung rale

lung slices

the blood and average stay were recorded. Before and after treatment

levels of CRP

ESR and PCT were detected. Result: In Ridit analysis

clinical effect in experimental group was superior to that in control group (P<0.05). After treatment

scores of the main symptoms and sings (cough

expectoration

sputum

wheeze

breathe hard

flustered and exasperated

lags in response

moist rales

excessive phlegm and bronchophony) were lower than those in control group (P<0.01). After treatment

time of fevers

cough

lung rale

recovery time in lung slices and blood examination as well as the average stay in experimental group were shorter than those in control group (P<0.05

P<0.01). Levels of CRP

ESR and PCT were also lower than those in control group after treatment (P<0.05

P<0.01). Conclusion: Maxin Shigan Tang combined with Tingli Dazao Xiefei Tang can relieve symptoms and signs

shorten courses

reduce levels of CRP

ESR and PCT

and improve clinical effect for the treatment of community acquired pneumonia (CAP) in middle-aged and old patients.
