title: [Correlative analysis of the parameters of eTRACKING detection of femoral artery and the syndrome types of traditional Chinese medicine in type 2 diabetic patients].
abstract: OBJECTIVE
  To explore the correlation between the parameters of eTRACKING detection of femoral artery and the syndrome types of traditional Chinese medicine (TCM) in type 2 diabetic patients so as to provide clinical evidence for early prevention and treatment of diabetic lower extremity arterial disease.
  
  
  METHODS
  A total of 147 cases of type 2 diabetic patients were included. Basic data and TCM clinical information were collected, and eTRACKING detection of common femoral arteries was performed. Differentiation of symptoms and signs for classification of TCM syndromes was performed in all patients. The correlations between TCM syndrome and pressure-strain elastic modulus (Ep), stiffness parameter beta, arterial compliance (AC), pulse wave velocity beta (PWVbeta), and augmentation index (AI) in common femoral arteries were observed.
  
  
  RESULTS
  In the patients with deficiency of both yin and yang, the Ep value was higher than that in the patients with deficiency of both qi and yin, the stiffness parameter beta was higher than that in the other three syndrome types (deficiency of both qi and yin, excessive heat due to yin deficiency, accumulation of damp-beat in spleen), the AC value was lower than that in the patients with excessive heat due to yin deficiency, the PWVbeta value was higher than that in the patients with excessive heat due to yin deficiency and deficiency of both qi and yin, and the AI value was higher than that in the patients with excessive heat due to yin deficiency. The stiffness parameter beta in the patients with deficiency of both qi and yin was higher than that in the patients with accumulation of damp-heat in spleen. In the patients with blood stasis, the Ep value was higher and the AC value was lower than that in the patients without blood stasis.
  
  
  CONCLUSIONS
  The decrease of elasticity in lower extremities can be detected by eTRACKING. This study reveals that type 2 diabetic patients with deficiency of both yin and yang, accumulation of damp-heat in spleen and blood stasis have more severe lower extremity arteriosclerosis. In eTRACKING parameters, stiffness parameter beta, AC and PWVbeta may become the objective indexes in evaluating early diabetic lower extremity arteriosclerosis.
