观察滋肾平产颗粒对左旋多巴诱导的运动障碍(LID)大鼠神经行为学表现及纹状体多巴胺D1、D2受体活性和基因表达的影响。建立正常对照组、LID模型组、中药干预组。每组治疗4周。应用人工神经网络挖掘影响LID大鼠神经行为学变化的主要因素。结果表明,多巴胺D1受体介导的直接通路的过度激活和多巴胺D2受体介导的间接通路的过度抑制可能是LID的主要机制。中医药主要通过上调多巴胺D2受体基因表达,延长LD有效改善LID症状的起效时间。
This study was performed to observe the effects of Zishenpingchan granule on neurobehavioral manifestations and the activity and gene expression of striatal dopamine D1 and D2 receptors of rats with levodopa-induced dyskinesias (LID). We established normal control group, LID model group, and TCM intervention group. Each group received treatment for 4 weeks. Artificial neural network (ANN) was applied to excavate the main factor influencing variation in neurobehavioral manifestations of rats with LID. The results showed that overactivation in direct pathway mediated by dopamine D1 receptor and overinhibition in indirect pathway mediated by dopamine D2 receptor may be the main mechanism of LID. TCM increased the efficacy time of LD to ameliorate LID symptoms effectively mainly by upregulating dopamine D2 receptor gene expression.
