Abstract
[Objective] To discuss the relationship between TCM syndrome differentiation and the frequency spectrum and the determined value of transcranial Doppler examination of arteria basilaris.[Methods] The frequency spectrum,systolic blood flow(Vs),pulsatility index(PI) of arteria basilaris were recorded in eighty patients with hypertension in several types in TCM syndrome differentiation by trancranial Doppler ultrasound apparatus.[Result] The overabundant liver-fire syndrome was frequently found in the first period of hypertension.The deficiency of yin and yang hyperactivity syndrome was in the second period.The deficiency of both yin and yang and obstruction and abundance of phlegm-damp were in the third period.The latter could also found in the second period of hypertension.The increased Vs value and normal PI could be seen in the first period.The increased or decreased Vs and elevated PI value in the second period.The decreased Vs and PI value in the third period.The decreased Vs and PI value in the third period.The increased Vs value and normal PI could be met in the overabundant liver-fire syndrome.The increased Vs and PI value in the patients with deficiency of yin leading to yang hyperactivity,while the decreased Vs and PI value in the deficiency of both yin and yang and obstruction and abundance in the patients with phlegm-damp.[Conclusion] We can see the developing course of syndrome differentiation of TCM in hypertension through the examination with transcranial Doppler ultrasound apparatus of arteria basilaris.
