用经颅多普勒超声（ＴＣＤ）对１００例脑梗塞病人中医辨证分组进行观察，并与３４例正常人作对照。结果表明，气虚血瘀组临床症状较轻，梗塞灶大多在单例，ＴＣＤ检测脑底动脉收缩峰血流速度（ＶＰ）及搏动指数（ＰＩ）均明显低于对照组，脑血管阻力系数（ＲＩ）明显高于对照组。肝肾阴虚组及痰瘀阻络组临床症状较重，梗塞灶大多在双侧，ＴＣＤ检测脑底动脉硬化，狭窄的发生率，ＰＩ、ＲＩ及大脑前、中动脉、颈内动脉终末段ＶＰ均明显高于对照组及气虚血瘀组，此两组之间无显著性差别。证实脑梗塞中医辨证之三组临床证候与脑底动脉血流变化密切相关。
Transcranial Doppler ultrasound (TCD) on 100 cases of cerebral infarction patients TCM Syndromes were observed, and 34 cases of normal controls. The results showed that the clinical symptoms of qi deficiency and blood stasis group were lighter and the infarct size was mostly single. The blood flow velocity (VP) and pulsatility index (PI) of TAC were significantly lower than those of control group RI) was significantly higher than the control group. The clinical symptoms of liver-kidney-yin deficiency group and phlegm-dampness obstruction group were severe, most of which were bilateral. The incidence of cerebrovascular atherosclerosis, stenosis, PI, RI and cerebral infarction Section VP were significantly higher than the control group and qi deficiency and blood stasis group, no significant difference between the two groups. Confirmed that cerebral infarction syndrome differentiation of the three groups of clinical syndromes and cerebral artery blood flow changes are closely related.
