Methods: Patients who were diagnosed with type 2 diabetes mellitus in Dongguan Branch of Yan'an University Affiliated Hospital between May 2013 and June 2017 were selected and divided into the CHD+DM group who were complicated by coronary heart disease and the DM group who were not complicated by coronary heart disease according to the results of coronary CTA, and the healthy subjects who received physical examination in Dongguan Branch of Yan'an University Affiliated Hospital during the same period were selected as control group. The contents of homocysteine (Hcy), uric acid (UA), platelet activation indexes and protease indexes in serum were measured. Results: Serum Hcy, UA, sSema4D, sP-selectin, sE-selectin, MMP1, MMP3, CatK and ADAMTS4 contents of DM group and CHD+DM group were greatly higher than those of control group whereas Klotho and TIMP2 contents were greatly lower than those of control group;serum Hcy, UA, sSema4D, sP-selectin, sE-selectin, MMP1, MMP3, CatK and ADAMTS4 contents of CHD+DM group were greatly higher than those of DM group whereas Klotho and TIMP2 contents were greatly lower than those of DM group;serum sSema4D, sP-selectin, sE-selectin, MMP1, MMP3, CatK and ADAMTS4 contents of CHD+DM group were positively correlated with Hcy and UA contents while Klotho and TIMP2 contents were negatively correlated with Hcy and UA contents. Conclusion: The abnormal increase of serum Hcy and UA contents in diabetic patients with coronary heart disease can promote the activation and aggregation of platelet, the degradation of plaque fibrous cap and the decrease of plaque stability.展开更多
