摘要Objective:To explore the value of fluid dynamic parameters and inflammatory factors in the prediction of early atherosclerosis in type 2 diabetes mellitus.Methods:A total of 126 patients with type 2 diabetes mellitus who were admitted to our hospital from March 2015 to July 2016 were selected as study subjects and divided into non atherosclerotic group (61 cases) and atherosclerosis group (65 cases)according to carotid artery IMT. At the same time, 60 healthy persons were selected as the control group. The fluid dynamics indexes (PSV, EDV and MV) and serum inflammatory factors (MCP-1, TNF-α and hs-CRP) were detected in the three groups.Results: There were no significant differences in PSV, EDV and MV between left and right carotid arteries in non-atherosclerotic group and control group. PSV, EDV and MV of left and right carotid artery were significantly lower in atherosclerosis group than those in control group. The carotid artery PSV, EDV and MV of left and right in atherosclerosis group were also significantly lower than those of non-atherosclerosis group. The MCP-1, TNF-α and hs-CRP levels in the non-atherosclerosis group were respectively (417.10±78.54), (85.72±9.97) and (3.73±0.61), significantly higher than those in the control group. The MCP-1, TNF-αand hs-CRP levels in atherosclerosis group were respectively (532.95±97.48), (123.56±12.85) and (5.39±0.74) , significantly higher than those in the control group and non-atherosclerosis group.Conclusion:Hydrodynamic parameters and serum inflammatory factors can be used as diagnostic criteria for carotid atherosclerosis in type 2 diabetic patients, and provide guidance for the early diagnosis of carotid atherosclerosis in patients with type 2 diabetes mellitus.
