The relationship between homocysteine and cerebral infaction in patients with type 2 diabetes mellitus / 天津医药

ABSTRACT

Objective To explore the correlation between serum homocysteine (Hcy) level and diabetes mellitus combined with cerebral infarction (DMCI) in patients. Methods A total of 144 patients with type 2 diabetes mellitus (T2DM) were selected and divided into two groups, patients without cerebral infaction (group A, n=64) and patients with cerebral infaction (group B, n=80). Thirty healthy people were used as control group (group C). The serum Hcy level was detected by enzymatic cycling assay in three groups. The serum levels of cholesterol (TC) and triglyceride cholesterol (TG) were detected by enzymatic determination. The serum levels of high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected by homogeneous phase method. The serum level of creatinine (Cr) was detected by creatine oxidase method. The level of uric acid (UA) was detected by urinary enzyme peroxidase coupling method. Glycosylated hemoglobin (HbA1c) was detected by high performance liquid chromatography. The carotid artery intima media thickness (IMT) was examined by color Doppler ultrasound, and patients were divided into mild and no stenosis group, moderate stenosis group and severe stenosis group according to the results. The levels of Hcy were compared between all groups. The correlation of Hcy level and other indicators was analyzed. Results The levels of Hcy and HbA1c were group C0.05). There were no significant differences in UA and Cr levels between the three groups (P>0.05). The level of Hcy was positively correlated with age (rs=0.411), HbA1c (rs=0.219) and Cr (rs=0.242), and negatively correlated with gender (rs=-0.202) and HDL-C (rs=-0.278, P0.05). With the increased degree of carotid artery stenosis, the Hcy level and the proportion of HHcy showed a rising trend in patients (P<0.01). The level of Hcy was positively correlated with IMT(rs=0.781, P<0.001). Conclusion Hcy is a risk factor for the onset of DMCI. The high level of Hcy is closely related to the occurrence and progression of atherosclerosis. Hcy has great value for early screening and prevention of DMCI.
