OBJECTIVE To explore the association between sleep disorders and dawn phenomenon in patients with type 2 diabetes mellitus (T2DM). METHODS From July 2011 to July 2014 at Metabolic Disease Hospital, Tianjin Medical University, 316 T2DM patients on continuous glucose monitoring were divided into two groups according to the Pittsburgh Sleep Quality Index,(More)
OBJECTIVE Accumulating evidence links the intestinal microbiota and colorectal carcinogenesis. Fusobacterium nucleatum may promote colorectal tumour growth and inhibit T cell-mediated immune responses against colorectal tumours. Thus, we hypothesised that the amount of F. nucleatum in colorectal carcinoma might be associated with worse clinical outcome. (More)
Embelin (2,5-dihydroxy-3-undecyl-1,4-benzoquinone, EB) has been shown to inhibit the X-linked inhibitor of apoptosis protein and various inflammatory pathways. Although different molecular mechanisms have been described for the potent antitumor activities of EB, its potential effect on inflammatory and immune-mediated diseases such as multiple sclerosis(More)
Colorectal cancer (CRC) remains a major contributor to cancer-related mortality. LIN28A and LIN28B are highly related RNA-binding protein paralogs that regulate biogenesis of let-7 microRNAs and influence development, metabolism, tissue regeneration, and oncogenesis. Here we demonstrate that overexpression of either LIN28 paralog cooperates with the Wnt(More)
The complex interactions between colorectal neoplasia and immune cells in the tumor microenvironment remain to be elucidated. Experimental evidence suggests that microRNA MIR21 (miR-21) suppresses antitumor T-cell-mediated immunity. Thus, we hypothesized that tumor MIR21 expression might be inversely associated with T-cell density in colorectal carcinoma(More)
OBJECTIVE To investigate the correlation between the frequency of dawn phenomenon and obesity in patients with type 2 diabetes. METHODS This study was conducted in 98 patients with type 2 diabetes admitted to the Metabolic Disease Hospital of Tianjin Medical University from 2011 to 2014. The subjects were divided into 3 groups according to BMI: the normal(More)
OBJECTIVE To investigate the effects of atorvastatin on bone formation, bone resorption and bone mineral density in Wistar rats. METHODS Sixty healthy male Wistar rats were randomly divided into one control group treated with vehicle alone and three drug treatment groups, which were treated with atorvastatin at 5 mg/kg x d, 25 mg/kg x d and 50 mg/kg x d(More)
Purpose Blockade of the programmed cell death 1 (PDCD1, PD-1) immune checkpoint pathway can improve clinical outcomes in various malignancies. Evidence suggests that aspirin (a widely used nonsteroidal anti-inflammatory drug) not only prolongs colorectal cancer survival, but can also activate T cell-mediated antitumor immunity and synergize with(More)
OBJECTIVE Evidence suggests that CD274 (programmed death-ligand 1, B7-H1) immune checkpoint ligand repress antitumour immunity through its interaction with the PDCD1 (programmed cell death 1, PD-1) receptor of T lymphocytes in various tumours. We hypothesised that tumour CD274 expression levels might be inversely associated with T-cell densities in(More)
PURPOSE Prostaglandin-endoperoxide synthase 2 (PTGS2, cyclooxygenase-2; a target of aspirin) produces inflammatory mediator prostaglandin E2 (PGE2), and contributes to colorectal neoplasia development. PTGS2-driven inflammatory responses can induce tumor expression of microRNA MIR21 (miR-21) that can increase local PGE2 level by downregulating(More)
