[Clinical research on children mental retardation treated with acupuncture]

To observe the impacts of acupuncture on intelligent structure, social adaptability and fMRI brain function in children mental retardation (MR).

Sixty cases of MR in compliance with the diagnostic standard were randomized into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, Sishenzhen [four points, 1.5 cun anterior, posterior and bilateral to Baihui (GV 20)], Zhisanzhen [Shenting (GV 24), bilateral Benshen (GB 13)], Niesanzhen (the point 2 cun directly above the ear a-pex, the two points 1 cun bilateral the first point) and Naosanzhan [Naohu (GV 17) and bilateral Naohu (GB 19)] were selected as the main points. In the medication group, piracetam tablets were prescribed for oral administration. One course of treatment was 4 months in the two groups. The comprehensive efficacy was compared between the two groups at the end of treatment course. China-Wechsler Intelligence Scale for Children (C-WISC) was used to assess the intelligent improvements. Infant-Junior School Student Social Life Ability Scale was adopted to assess the improvements of social adaptability. Five cases were selected from the acupuncture group and fMRI was adopted to compare the brain function imaging changes before and after acupuncture treatment.

In the acupuncture group, the final intelligence quotient (FIQ) and social adaptability score after treatment were higher than those before treatment (P<0.05), of which, the performance intelligence quotient (PIQ) was improved significantly, indicating the statistically significant difference (P<0.05). But the verbal intelligence quotient (VIQ) did not change apparently (P>0.05). In the medication group, the changes in all the indices were not apparent before and after treatment (P>0.05). In comparison of the changes after treatment between the two groups, FIQ, PIQ and social adaptability score in the acupuncture group were improved more significantly as compared with the medication group (P<0.05). The fMRI brain function images did not change apparently before and after treatment in those 5 cases of the acupuncture group.

Acupuncture promotes the intelligent recovery of MR children and improves their social adaptability. It indicates the satisfactory clinical efficacy. But, the fMRI brain function images do not change apparently before and after treatment.
