Objective To investigate the expression of glucocorticoid receptor-alpha and beta(GR?and GR?)mRNA of peripheral blood mononuclear cells(PBMCs)in patients with dermatomyositis/polymyositis (DM/PM)and analyze their association with the pathogenesis and clinical response to glucocorticoid therapy. Methods The expression of GR?and GR?mRNA in PBMCs from 20 normal controls and 36(24 steroid- sensitive,12 steroid-resistant)patients with DM/PM were detected by reverse transcription polymerase chain reaction(RT-PCR).Results Compared to normal controls,the expression of GR?mRNA in the DM/PM was significantly decreased(P

0.05).But GR number[sites/cell]and the expression of GR mRNA in PBMCs from PM/DM was significantly lower than those in healthy controls(P

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.
