The Expression of CD14+CD16+ Monocyte Subpopulation in Coronary Heart Disease Patients with Blood Stasis Syndrome

الملخص EN

Blood stasis syndrome (BSS), a comprehensive pathological state, is one of the traditional Chinese medicine syndromes of coronary heart disease (CHD).

In our previous study, we investigated that FcγRIIIA (also called CD14+CD16+ monocyte subpopulation) is one of the differentially expressed genes related to CHD patients and its possible role in the atherosclerotic formation and plaque rupture.

However, whether or not the deregulation of CD14+CD16+ monocyte subpopulation expression is implicated in the pathogenesis of CHD patients with BSS has not yet been elucidated.

In this study, we found that there was no significant difference between CHD patients with BSS and non-BSS in CD14+CD16+ monocyte subpopulation at gene level.

Moreover, the protein level of CD14+CD16+ monocyte subpopulation in CHD patients with BSS was increased significantly when compared to the CHD patients with non-BSS.

Additionally, the level of inflammatory cytokines downstream of CD14+CD16+ monocyte subpopulation such as TNF-α and IL-1 in sera was much higher in CHD patients with BSS than that in CHD patients with non-BSS.

Taken together, these results indicated that CD14+CD16+ monocyte subpopulation was implicated in the pathogenesis of CHD patients with BSS, which may be one of the bases of the essence of BSS investigation.
