Asprosin, coiled-coil domain-containing 80(CCDC80) and angiopoietin-like4(ANGPTL4) are newly discovered adipocytokine that affects glucose tolerance, insulin resistance and cardiovascular diseases. The goal of this study was to investigate if a relationship exists among asprosin, CCDC80 and ANGPTL4 and inflammatory bowel disease (IBD). Fifty subjects with newly diagnosed IBD and fifty healthy individuals were enrolled. Patients were treated with standard therapies for 3 months. Plasma asprosin, CCDC80 and ANGPTL4 levels were measured with enzyme-linked immunosorbent assay. High resolution ultrasound was used to measure brachial artery diameter at rest, after reactive hyperemia (flow-mediated dilation, FMD) and after sublingual glyceryltrinitrate.Compare with healthy individuals, plasma CCDC80,erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels and homeostasis modelassessment of insulin resistance (HOMA-IR) were significantly higher (p < 0.05, respectively), whereas plasma asprosin,ANGPTL4 levels and FMD were significantly lower inboth UC and CD patients(p <0.05). Plasma CCDC80 levels were significantly higher in patients with CD (p<0.05), while plasma asprosin and ANGPTL4 levels were lower (p<0.05) as compared with those in patients with UC. Standard therapies increased plasma asprosin, ANGPTL4 levels and FMD in both UC and CD (p<0.05),UC and CD patientswhile decreased plasma CCDC80, ESR, CRP levels and HOMA-IR (p<0.05). The changes in HOMA-IR and FMD were correlated with the changes in plasma asprosin, CCDC80 and ANGPTL4 levels over the study period (p<0.05). Plasma asprosin, CCDC80 and ANGPTL4 levels may be applied as a significant marker for early stage of insulin resistance and atherosclerosis in IBD, especially of CD.

High-mobility group box 1 (HMGB1) is newly discovered protein, which play a crucial role in the pathogenesis of systemic inflammation. Recent studies showed that HMGB1 is one of the important pathophysiological mechanisms in the occurrence and development of atherosclerosis. The purpose of the present study was to investigate the relationship between serum HMGB1 levels and endothelial function in patients with polycystic ovary syndrome (PCOS). Eighty newly diagnosed patients with PCOS and eighty normal women of similar age were selected. Metformin treatment (1,500 mg/day) was initiated in all patients for a period of consecutive 3 months. Serum HMGB1 levels were measured by ELISA. High resolution ultrasound was used to measure the brachial artery diameter at rest, after reactive hyperemia (flow-mediated arterial dilation, FMD) and after sublingual glyceryltrinitrate. Serum HMGB1 levels in PCOS were 24.87+/-14.93 ng/ml, which were significantly higher than that in controls (8.82+/-3.55 ng/ml, p<0.01). After 3 months treatment, serum HMGB1 levels decreased significantly (p<0.05). By dividing the distribution of HMGB1 levels into quartiles, serum HMGB1 levels were increased gradually with the increase of testosterone levels (p<0.05), whereas the FMD levels decreased (p<0.05). Multiple stepwise linear regression analysis showed that FMD (estimated coefficient beta=-0.69, p=0.005), testosterone (beta=0.31, p=0.045), TBARS (beta=0.69, p=0.012) and hs-CRP levels (beta=0.68, p=0.001) were significantly associated with HMGB1. The absolute changes in HMGB1 showed a positive correlation with the changes in testosterone (p<0.05) and negative correlation with the changes in FMD (p<0.05) in patients with PCOS during the course of metformin therapy. Serum HMGB1 levels are correlated with endothelial dysfunction in patients with PCOS. Our study suggests that HMGB1 may contribute to the early stage of atherosclerosis in patients with PCOS.
