Objective To study the correlation between the TCM syndrome elements and interleukin-6（IL-6） in hypertension patients.Methods Totally 321 hypertension patients collected were investigated with a method of syndrome element judgment and serum content of IL-6 was determined.The regression analysis was carried out to study the correlation between the TCM syndrome elements and IL-6.Results The main syndrome elements of hypertension were stasis（178 patients

55.45%） and fire or heat（164 patients

51.09%）.The stasis was in positive correlation with IL-6（P<0.01）.Conclusion Stasis is the most common syndrome element of hypertension and its formation is possibly correlated with the increase of IL-6 level.
