RESUMEN
Objective To discuss effects of anti-inflammatory mechanism of amygdalin on rats with type II collagen-induced arthritis (CIA). Methods Wistar rats were randomized into normal group, model group, amygdalin group, and tripterygium group. Type II CIA rat models were established. From the 15th day after the modeling establishment, each administration group was given corresponding dose of medicine for continuous 28 days. Levels of TNF-αand sICAM-1 were detected by ELISA in serum of rats, and expression of TNF-α was detected by immuno-histochemical method. Results TNF-α positive expression in amygdalin group and tripterygium group was similar and significantly reduced compared with model group. Levels TNF-α and sICAM-1 in amygdalin group and tripterygium group significantly decreased compared with those in model group (P0.05). Conclusion Amygdalin can inhibit the expression of TNF-α and levels of TNF-α and sICAM-1, in order to treat rheumatoid arthritis.
RESUMEN
<p><b>OBJECTIVE</b>To test the feasibility of using 1,5-anhydroglucose alcohol (1,5-AG) as a diagnostic indicator of fulminant type 1 diabetes (FT1DM).</p><p><b>METHODS</b>Fifteen patients with newly diagnosed FT1DM and 52 with type 2 diabetes (T2DM) were examined for serum biochemistry, glycosylated hemoglobin (HbAlc), and serum 1, 5-AG level.</p><p><b>RESULTS</b>The patients with FT1DM and T2DM showed significantly different fasting levels of blood glucose (FBG), fructosamine (FMN), creatinine (Cr), urea, HbAlc and serum 1,5-AG (P<0.05). In FT1DM patients, serum 1,5-AG was found to inversely correlate with FBG (r=-0.646, P=0.032) and FMN (r=-0.680, P=0.021), and in T2DM patients, serum 1,5-AG was inversely correlated with FBG (r=-0.407, P=0.001), FMN (r=-0.314, P=0.01) and HbAlc (r=-0.576, P<0.01). Receiver-operating characteristic (ROC) curve analysis showed an area under the curve of serum 1,5-AG of 0.804 with a cutoff value of 67.95, a sensitivity of 82.9% and a specificity of 60% for FT1DM diagnosis.</p><p><b>CONCLUSION</b>Serum 1, 5-AG can reflect acute blood glucose fluctuation in FT1DM patients and is useful for differential diagnosis of FT1DM when combined with evaluations of the clinical characteristics of the patients and other related indicators.</p>
