Description for medicine or protocol of treatment in detail:

Using metabolomics approaches, to detect alterations of serum metabolite profiling in individuals with normal glucose tolerance (NGT), impaired glucose tolerance (IGT), or type 2 diabetes (T2DM), which living at Tibet plateau or plain. Relevant metabolic pathway analysis will be performed by MetaboAnalyst software and KEGG pathway database. 1.Total of 180 subjects will be enrolled in this study and divided into higher altitude group (group H, altitude height ≥2800m) and lower altitude group (group L, altitude height <500m). Of each group, the subjects will be further divided into 3 subgroups (group NGT, group IGT, or group T2DM) based on their glucose tolerance status, 30 participants in each subgroup. 2.Clinical characteristics of the subjects will be collected such as age, gender, race, duration of residence, duration of diabetes, hypertension, or dyslipidemia, and etc. 3.Anthropometric measurements will also be collected such as height, body weight, waist circumference, hip circumference, systolic / diastolic blood pressure, heart beat, blood oxygen saturation (SaO2). 4.Lab examination: Blood samples will be collected for the detection of RBC, Hb, Hct, FPG/P2hPG, FINS/P2hINS, F-CP/P-2hCP, HbA1c, lipid profiles, and etc. HOMA-IR=FPG(mmol/L)×FINS(mIU/L)/22.5, HOMA-β=20×FINS(mIU/L)/[FPG(mmol/L)-3.5] 5.Serum samples will be collected and stored at -80℃ for detection of metabolite profiling and analysis of metabolic pathways.
