Abstract

The protective effect of high‑density lipoprotein (HDL) on endothelial function is impaired in patients with type 2 diabetes mellitus (T2DM), which may result in atherosclerotic complications. Naoxintong (NXT) is a compound preparation that includes Radix Astragali, Angelicae sinensis, Radix Paeoniae Rubra and Ligusticum wallichii. It is widely administered in China to prevent atherosclerotic complications. In the present study, NXT was administered to 69 patients with T2DM. HDLs were isolated from patient blood samples prior to and following the intervention. In vitro endothelial functions of HDL, including proliferation, migration, angiogenesis, and anti‑apoptosis were investigated by bromodeoxyuridine, wound healing, Transwell and Matrigel tube formation assays on human umbilical vein endothelial cells (HUVECs). The results from the present study demonstrated that HUVECs treated with HDL isolated from diabetic patients following NXT therapy exhibited increased proliferative effects (10‑27%; P<0.05), and improved migration ability (15‑35%; P<0.05), anti‑apoptotic function (23‑34%; P<0.05) and angiogenesis (30‑54%; P<0.001). Furthermore, the phosphorylation levels of Akt (26‑36%; P<0.01) and extracellular signal‑regulated kina...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

CV Disorders & Type 2 Diabetes

This feed focuses on the association of cardiovascular diseases in patients with type 2 diabetes.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
