脑功能成像技术在穴位特异性研究中的应用

Application of cerebral function imaging in research on the acupoints specificity

探讨脑功能成像技术在穴位特异性研究中的作用。检索利用脑功能成像技术研究穴位激活脑区方面的相关文献,对比分析其研究。结果发现:①针刺可改善脑血管病患者的脑血流低灌注状态,这可能是针刺治疗效应机制;②针刺治疗具有选择性调节作用,其效应与人体的状态和脑功能区的状态有关;③脑功能成像技术可以明确区分针刺的治疗作用和安慰作用;④穴位在激活脑区方面有一定的特异性,但不同实验所得结果不完全相同。脑功能成像技术可以用于研究经穴特异性,但诸多干扰因素影响实验的准确性,为了使实验设计更严谨,实验结果更具有说服力,今后的实验设计有待完善。

To explore the effect of cerebral function imaging in research on the acupoints specificity. Relevant literatures are retrieved and their results are compared. The results reveals as the follows： ① Acupunture can ameliorate cerebral blood flow hypoperfusion in patients with cerebrovascular disease, which maybe one of the mechanisms of acupuncture effect; ② Acupuncture treatment has selectivity regulation role, which is related to the state of body and brain; ③Cerebral function imaging can draw a clear distinction between therapeutic effect and placebo effect of acupuncture; ④The points have specificity on the brain activation, but the outcomes are not exactly the same under different experimental conditions. Cerebral function imaging can be used to exploring acupoints specificity. Due to many interference factors which influence the accuracy of experiment, the subsequent experimental design have to be improved in the days ahead so as to make the results more cogent and rigorous.
