Objective: To examine the associations between inflammatory markers, coagulation and fibrinolysis parameters, and microvascular complications in 182 Chinese patients with type 2 diabetes mellitus (T2DM) who sought treatment at a large hospital in Zhejiang province, China. Methods:We investigated the relationships of blood inflammatory markers with hemostatic markers in 87 patients with T2DM who did not have complications and 95 patients with T2DM who had microvascular complications.Results: C-reactive protein (CRP) and interleukin-6 (IL-6) were significantly correlated with fibrinogen, thrombin-antithrombin III complex (TAT III), plasminogen activator inhibitor-1 (PAI-1), von Willebrand factor (vWF), and coagulation factors (F) VII in patients with T2DM who had microvascular complications (P <.05). Based on logistic regression analysis, the highest-tertile groups of fibrinogen, FVII, and FVIII, corresponded to a greater risk of high CRP, whereas risk of high IL-6 was significantly greater in the groups with highesttertile values for fibrinogen, FVII, TAT III, PAI-1, and activated protein C (APC).Conclusions: Elevated levels of CRP and IL-6 might be associated with increased coagulability and a tendency towards thrombus formation in patients with T2DM who have microvascular complications.

Lipid metabolic disturbances are related to many diseases, such as obesity, diabetes, and certain cancers. Notably, lipid metabolic disturbances have been reported to be a risk factor for colorectal cancer. Nuclear receptors act as ligand-dependent transcription regulators and play key roles in the regulation of body lipid metabolism and the development of many cancers. Retinoic acid receptor-related orphan receptor α (RORα) is a nuclear receptor and can regulate several lipid metabolism genes in certain cancers. Herein, we demonstrate that the conditioned medium from adipocytes has a proproliferative and promigratory effect on colorectal cancer cells and enhances angiogenesis in chicken embryonic chorioallantoic membranes. In addition, the conditioned medium leads to a decrease in the expression of RORα and its target genes. Meanwhile, RORα and its target gene expressions are lower in human colorectal tumor tissue compared with control colorectal tissue. Activation of RORα inhibits the effect of conditioned medium on the proliferation and migration of colorectal cancer cells as well as the angiogenesis in chicken embryonic allantoic membranes. In colorectal cancer cells, the putative ligand of RORα, cholesterol sulfate (CS), prevents cell cycle progression at the G1/S boundary and concurrently modulates the expression of cell cycle-regulatory genes in colorectal cancer cell. CS inhibits angiogenesis in chicken embryonic chorioallantoic membranes and concurrently decreases the mRNA expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1α as well as the secretion of VEGF. In addition, lipogenic gene expression is higher in human colorectal tumor tissue compared with control colorectal tissue. CS inhibits the expression of lipogenic genes in colorectal cancer cells. These results suggest that RORα could represent a direct link between local lipid metabolism of colorectal tissue and colorectal cancer. Therefore, the reduction of the expression of RORα could represent a potential warning sign of colorectal cancer.
