title: [Assessment on effect of treatment for childhood hyperkinetic syndrome by combined therapy of yizhi mixture and ritalin].
abstract: OBJECTIVE
  To seek for a good therapy for childhood hyperkinetic syndrome (CHS).
  
  
  METHODS
  Two hundred and ten patients of CHS were randomly divided into three groups, the Yizhi mixture (YZM) group, the Ritalin group and the combined treated group, 70 in each group. They were treated with YZM alone, Ritalin alone and combined YZM and Ritalin respectively for 12 weeks. The effect was assessed by Conners' questionnaire for hyperkinetic scoring, Achenbach's questionnaire for behavior estimation, clinical general image questionnaire and Tess's questionnaire before and after treatment.
  
  
  RESULTS
  The total effective rate in the YZM group, Ritalin group and combined treated group was 75.7%, 74.2% and 82.8% respectively, and the markedly effective rate in the three groups was 44.3%, 45.7% and 80.0% respectively. By chi 2 test, comparison among the three groups showed that the difference of the total effective rate was insignificant, while that of the markedly effective rate was significant (chi 2 = 23.31, P < 0.01). Further analysis conducted by partitioning method to make comparison between each two groups showed that the markedly effective rate was significantly higher in the combined treated group than that in the YZM group (chi 2 = 18.98, P < 0.01) and in the Ritalin group (chi 2 = 17.62, P < 0.01). The low hyperkinetic score, behavior score, achievement of Chinese and mathematics in the CHS patients were improved after treatment, the improvements were significantly higher in the combined treated group than those in the other two groups (P < 0.05, by q-test). Moreover, the soft nerve signs and abnormal encephalogram were significantly improved in the combined treated and the YZM groups, and the side-effect occurred in the two groups was less than that in the Ritalin group (P < 0.01).
  
  
  CONCLUSIONS
  The therapeutic effect of combined treatment of YZM and Ritalin was better than that of YZM or Ritalin alone.
