Study on the expression of CD14 + CD16 + monocytes and VEGF in peripheral blood of patients with type 2 diabetes mellitus and diabetic macroangiopathy

Objectives To study the expression of CD14 + CD16 + monocytes and VEGF and the levels of serum adiponectin and MCP-1 in peripheral blood of patients with type 2 diabetes mellitus (T2DM) and diabetic macroangiopathy to understand the possible mechanism of inflammatory immune response in T2DM and diabetic macroangiopathy. Methods Peripheral blood CD14 + CD16 + monocytes were detected by flow cytometry in 50 T2DM patients, 50 patients with diabetic macroangiopathy, and 20 healthy controls or normal controls who participated in outpatient physical examination, and used the Ficoll-Hypaque density gradient centrifugation isolated PBMC and quantitative PCR technology comparison between groups research object in the peripheral blood PBMC VEGF mRNA expression level. Serum levels of adiponectin and MCP-1 were measured by ELISA. Results Compared with normal control group (NGT), the fluorescence intensity of proinflammatory CD14 + CD16 + monocytes in simple T2DM group and T2DM combined with macroangiopathy group were significantly increased ( p healthy volunteers, the differences were significant ( p
