title: [Changes of platelet α-particle membrane protein, platelet activating factor and platelet parameters in patients with hyperuricemia].
abstract: This study was aimed to investigate the changes of the platelet particle membrane protein (GMP-140), platelet activating factor (PAF) and platelet parametes in the patients with hyperuricemia (HUA), ELISA was used to detect the levels of GMP-140 and PAF in 55 patients with HUA and 30 healthy individuals. Platelet parameters were measured with automatic blood cell analyzer, and the biochemical indexes were detected at the same time. The results showed that the levels of serum uric acid, triglycerides (TG) and low density lipoprotein cholesterol (LDL-C) in HUA patients were higher than that in the normal group (P < 0.01). Serum uric acid level of HUA group was higher in men than that in women. The levels of GMP-140 and PAF in HUA patients were much higher than that in the normal group (P < 0.01), the indexes of platelet distribution width (PDW) and platelet-large cell ratio (P-LCR) in HUA patients were higher than that in the normal group (P < 0.01), there was no statistically significant difference in platelet count, plateletcrit (PCT), mean platelet volume (MPV) between the two groups. There was positive correlation between serum uric acid and levels of GMP-140, PAF, P-LCR and PDW, respectively (r = 0.667, 0.879, 0.310, 0.460, P < 0.01 or P < 0.05). Multivariate stepwise regression analysis revealed that serum uric acid, creatinine, P-LCR, urea nitrogen contributed to GMP-140 level (adjusted R(2) = 0.822). Serum uric acid and LDL-C also contributed to PAF level (adjusted R(2) = 0.451). It is concluded that a close relationship exists between HUA and the change of platelet function, and HUA plays a certain role in cardiovascular disease thrombosis complications.
