Abstract: Objective：WT5”BZ〗To explore evolvement characteristics of syndrome types and distribution characteristics of different ages of TCM syndromes in infantile pneumonia.WT5”HZ〗Methods：WT5”BZ〗Through the clinical observation of 380 children patients with infantile pneumonia, we observed and recorded the syndrome types of the patients on the day of admission (basic point), and on the 3rd, 5th, 7th and 10th day after medication， to explore evolvement characteristics of syndrome types in different observation period. JP2〗We also observed the correlation between the distribution of TCM syndromes and ages on the day of admission.WT5”HZ〗Results：WT5”BZ〗Of the 380 cases of pneumonia in children，from baseline point to the 3rd day after treatment，wind-heat lung affection and phlegm-accumulation lung affection were the major types，and fewer cases had change of types.Five days after treatment，the above-mentioned two types were still the major ones，but most cases had change of types.On the 7th day of treatment，some cases changed to Yin-deficiency lung affection and insufficiency of lung-qi and spleen-qi.On the tenth day，most of the wind-cold lung affection，wind-heat lung affection and phlegm-accumulation lung affection turned to normal cases.Of the 380 cases of pneumonia，phlegm-accumulation lung affection and toxic-heat lung affection were presented mainly in children aged one to three，wind-heat lung affection and phlegm-accumulation lung affection were presented mainly in children aged 4 to 7，and wind-cold lung affection and wind-heat lung affection were presented mainly in children aged 8 to 14.JP〗WT5”HZ〗Conclusion：WT5”BZ〗TCM syndromes of infantile pneumonia is a dynamic evolution process during the whole disease course, so distribution of each type has certain characteristics in different periods. There is correlation between distribution of TCM syndromes and ages.
