Abstract:
Objective To evaluate the therapeutic effects of methamphetamine (MA) dependence and the repairment of DA neuronal function by SPECT corpus striatum DAT visual digital neural molecular imaging techniques.Methods 25 MA dependent patients (BPRS score ≥ 35) were treated by self-designed treatment program for more than 6 months.The clinical therapeutic effects were scored with reducing rate of BPRS.MA dependent patients were examined by SPECT corpus striatum DAT imaging before and after treatment,while healthy volunteers were examined only once.The SPECT corpus striatum DAT images were analyzed visually and quantitatively.Results The reducing rate of BPRS showed that the total effective rate was 80.0％.Visual analysis of SPECT corpus striatum DAT images showed that the distribution of DAT in the corpus striatum was regionally reduced or defected in various degrees before treatment,and was significantly increased after treatment.Quantitative analysis showed that the bilateral striatal V ((19.26 ± 2.85) cm3),m((20.22±2.99) g) and Ra(4.78±0.79) ％) of MA dependent patients were significantly lower compared with those of the healthy volunteers(respectively (35.39±4.42) cm3,(37.16±4.64) g and (7.93± 0.86) ％) (all P＜ 0.01) before treatment and were significantly improved (P＜ 0.01) after treatment (V:(22.80±4.28) cm3,m:(23.93± 4.49) g and Ra:(5.64 ± 0.99) ％) with a 76.0％ corpus striatum DAT improvement rate.However,the bilateral striatal V,m and Ra of MA dependent patients after treatment were still lower than those of the healthy volunteers (P＜0.01).There was no significant difference between the striatal DAT improvement rate and the BPRS reduction rate (P＞ 0.05).Conclusion SPECT corpus striatum DAT visual digital neural molecular imaging techniques are reliable in the evaluation of the treatment programs for MA dependence and the repair of DA neuronal function.
