GPT and Insulin resistance: In addition, serum metabolic parameters, including liver enzyme (alanine aminotransferase (ALT), aspartate transaminase (AST), glutamyl-transpeptidase (GGT), alkaline phosphatase (ALP)), blood lipids (high-density lipoprotein-cholesterol (HDL-c), low-density lipoprotein-cholesterol (LDL-c), TG, and TC), inflammatory factors (tumor necrosis factor α (TNF-α), C reactive protein (CRP), and interleukin-6 (IL-6)), and glycometabolic indicators (fasting blood glucose (FBG), fasting insulins (FINS), and insulin resistance (HOMA-IR)) were monitored at the end of this study.
