Objective To observe therapeutic effects of decoction of clearing heat

promoting dieresis

invigorating the circulation of blood and removing toxin combined with western medicine on abdominal type anaphylactoid purpura with syndrome of damp toxin accumulating inside. Methods A total of 111 children with abdominal type anaphylactoid purpura of damp toxin accumulating syndrome were randomly divided into treatment group（ 75 cases）and control group（ 36 cases）. The control group was given intravenous drip with prednisolone sodium succinate

2 mg /（ kg·d）

once every 12 h

and reduced the methylprednisolone according to state of illness after full dose for 3

5 days. At the same time the control group was given intravenous drip with vitamin C 0. 2 g and aminomethylbenzoic acid

50 mg once a day. Additionally

the treatment group orally took decoction of clearing heat

promoting dieresis

invigorating the circulation of blood and removing toxin

1 dose daily. Courses of treatment were 2 weeks. Before and after the treatment

respectively graded symptoms of abdominal pain

hemafecia

hematemesis

emesis

loss of appetite

abdominal distension

skin purpura and abdominal B ultrasonic and observed the time of abdominal pain disappearing in the two groups to evaluate clinical effects. Results In the treatment group

remarkably effective rate was85. 4%

total effective rate was 96. 0%

while that was 69. 5% and 94. 5% respectively in the control group. The difference between both groups was statistically significant（ P

<

0. 05）. After treatment

scores of abdominal pain

loss of appetite

abdominal distension

skin purpura and abdominal B ultrasonic and aggregate score of both groups were lower than those before treatment（ P

<

0. 05）. After treatment

scores of abdominal pain

loss of appetite and abdominal B ultrasonic and aggregate score in the treatment group were lower than those in the control group（ P

<

0. 05）. After treatment

hemafecia

hematemesis

emesis disappeared in the two groups. In the treatment group

the time of abdominal pain disappearing was shorter than that in the control group（ P

<

0. 05）. Conclusion The efficacy of clearing heat

promoting dieresis

invigorating the circulation of blood and removing toxin combined with western medicine for abdominal type anaphylactoid purpura with syndrome of damp toxin accumulating inside was superior to the treatment of only western medicine. It may obviously improve symptoms and signs and shorten the time of abdominal pain disappearing.
