Objectives: To investigate the treatment effect between insulin,metformin and Liraglutide; in Type 2 Diabetes in our hospital, in order to investigate the possible mechanism about telomere-telomerase system and Par-4.
160 Type 2 diabetes in our hospital will divide into 4 groups: group A (40 healthy volunteers), group B (40 patients who give basal and insulin treatment, group C(40 patients who give basal and Liraglutide treatment),group D(40 patients who give basal and metformin treatment). The age, height, weight, blood glucose, glycosylated hemoglobin A1c(HbA1c),homeostasis model assessment(HOMA-IR), lipid, blood pressure, course of disease, telomere length,telomerase activity will record respectively. And High-sensitive C-reactive protein (HsCRP), Par-4, GST,SOD,GSH-PX,ATF-6,CHOP,XBP-1 and Tumor necrosis factor-α(TNF-α) will detect as Baseline. After each group's treatment, Change from baseline of all indexes will record, Multifactor logistic regression will be analyzed the correlations between each positive indexes.
