Abstract:Objective To explore the correlation of the ratio of total cholesterol (TC) to high-density lipoprotein cholesterol (HDL-C), triglyceride (TG) to HDL-C, low-density lipoprotein cholesterol (LDL-C) to HDL-C, homeostasis model assessment-β (HOMA-β) and hypersensitive C-reactive protein (hsCRP) with insulin resistance.Methods A total of 134 patients with T2DM who were hospitalized in the Department of Endocrinology of the Second Hospital of Jilin University from January 2022 to August 2022 were selected. According to the interquartile range of insulin resistance index (HOMA-IR) assessed by homeostasis model, the patients were divided into four groups, group A (HOMA-IR < 3.6889), group B (3.6889 ≤ HMOA-IR < 5.5793), group C (5.5793 ≤ HOMA-IR < 8.6986), group D HOMA-IR ≥ 8.6986). The blood biochemical indicators, blood cell ratio and lipid ratio were compared among the four groups of patients, and the correlation with insulin resistance was observed.Results TG, TG/HDL-C, FBG, HbA1c, FINS, HOMA-IR, HOMA-β, monocyte count (P < 0.05) among four groups A, B, C, and D There is a difference, and the difference is statistically significant. Compared with group A, the levels of FINS and HOMA-IR in group B increased (P < 0.05), and the levels of TG, TG/HDL-C, FINS, HOMA-IR, and monocyte count in group C increased (P < 0.05), the levels of FBG, FINS, HOMA-IR, HOMA-β in group D increased (P < 0.05); compared with group B, the level of HOMA-IR in group C increased (P < 0.05), D The levels of FBG, HOMA-IR, and FINS in the group increased (P < 0.05); compared with group C, the levels of FINS and HOMA-IR in group D increased (P < 0.05). Spearman correlation analysis showed that HOMA-IR was correlated with TG (rs = 0.234, P =0.007), TC/HDL-C (rs = 0.234, P = 0.006), TG/HDL-C (rs = 0.258, P =0.003), FBG (rs = 0.321, P = 0.000), HbA1c (rs = 0.236, P = 0.006), FINS (rs = 0.844, P = 0.000), HOMA-β (rs = 0.265, P = 0.002), monocyte count (rs = 0.245, P = 0.004), LDL-C/HDL-C (rs = 0.172, P = 0.046), and high-sensitivity C-reactive protein (rs = 0.170, P =0.049) were positively correlated with PNR (rs = -0.196, P = 0.023) were negatively correlated. The results of multiple linear regression analysis showed that FBG, HbA1c, FINS, and monocyte count were independent risk factors for HOMA-IR in T2DM patients (P <0.05).Conclusion The increase of LDL-C/HDL-C, TC/HDL-C, TG/HDL-C, HOMA-β and hypersensitive C-reactive protein in patients with T2DM is correlated with insulin resistance. FBG, HbA1c, FINS, and monocyte count are independent risk factors for HOMA-IR in T2DM patients.
