ABSTRACT
Glucose is the central nutrient for energy metabolism and life support in the human body. As the main energy substance of the body, glucose is essential for the normal function of immune cells and their proliferation; when glucose homeostasis is disrupted in the body, it may lead to impaired immune system function and pathological conditions. Exploring the relationship between glucose metabolism and immune regulation can help establish the gene regulatory network and figure out potential pathogenic mechanisms under physiological and pathological conditions. This article reviews the current scientific research progress on glucose metabolism and immunity, mainly focusing on the physiological regulatory functions of glucose in maintaining the homeostasis of innate and acquired immunity; and summarizes the research progress on the effects and mechanisms of glucose on tumor immunity and its related therapies under pathological conditions, taking tumors as an example.

<p><b>OBJECTIVE</b>To investigate the effect of genetic polymorphisms in VKORC1, CYP2C9, GGCX, EPHX1, APOE genes on inter-individual variation in warfarin maintenance dose.</p><p><b>METHODS</b>Two hundred and forty-nine patients with stable warfarin dose were enrolled in this study, and the clinical data and blood samples of the patients were collected. Genotypes for the 5 genes were determined by using PCR and denaturing high performance liquid chromatography (DHPLC) assay. The warfarin maintenance doses were compared among patients with different genotypes of the 5 genes, and a warfarin stable dosing algorithm was derived based on genetic and non-genetic factors.</p><p><b>RESULTS</b>Of the 5 genes, VKORC1, CYP2C9 and GGCX were associated with warfarin stable dose. The multiple linear regression analysis indicated that VKORC1, CYP2C9 and GGCX genes, age and weight, had significant influence on inter-individual variation in warfarin stable dose, which contributed 30.2%, 22.8%, 1.5%, 4.7% and 6.7% respectively. The warfarin stable dosing algorithm acquired from the optimal regression model could explain 57.8% variation in warfarin dose.</p><p><b>CONCLUSION</b>This study suggested that genetic factors are the major determinants of the warfarin maintenance dose, and warfarin stable dosing algorithm may be useful for helping clinicians to prescribe warfarin with greater safety and efficiency.</p>
