Objective:To investigate the relationship between inflammatory factors and two Chinese medicine (CM) syndrome types of qi stagnation and blood stasis (QSBS) and qi deficiency and blood stasis (QDBS) in patients with acute coronary syndrome (ACS).Methods:Sixty subjects with ACS,whose pathogenesis changes belongs to qi disturbance blood stasis syndrome,were divided into 2 groups:30 in the QSBS group and 30 in the QDBS group.The comparative analysis on them was carried out through comparing general information,coronary angiography and inflammatory factors including intracellular adhesion molecule-1 (ICAM-1),chitinase-3-like protein 1 (YKL-40) and lipoprotein-associated phospholipase A2 (Lp-PLA2).Results:Compared with the QSBS group,Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference (P＞0.05);ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS (P＜0.05).Conclusion:Inflammatory factor ICAM-1 may be an objective basis for syndrome typing of QSBS and QDBS,which provides a research direction for standardization research of CM syndrome types.
