Considering the clinical symptoms and the endoscopic manifestations of the abdominal-type Henoch-Schonlein purpura（HSP）

professor YAN Huimin believes that this disease can be classified into "internal abscesses" as it is highly similar to the "redness

swelling

heat and pain" characteristics of internal abscesses in traditional Chinese medicine

and has similar disease mechanism which were qi and blood congestion and constraint

and blood vanquished and flesh putridity. During acute stage

clearing heat

dispelling damp and regulating qi method is recommended

as well as cooling blood

dispelling stasis and unblocking collaterals; in the convalescence period

nourishing blood

quickening the collaterals

fortifying spleen and dispelling dampness should be performed. The gastroscopy results could be combined for local microscopic syndrome differentiation; if there were obvious gastrointestinal mucosal congestion and swelling

heat-clearing and abscess-resolving method should be applied; for patients with multiple erosions and ulcers in the mucous membrane

it is advised to dispel stasis and unblock collaterals

close sore and engender flesh; regarding bile reflux or turbid mucus pool seen under the microscope

the function to clear damp-heat should be strengthened.
