摘要 目的观察2型糖尿病患者外周血白细胞磷酸戊糖途径(PPP)关键酶———葡萄糖-6-磷酸脱氢酶(G6PD)活性、还原型辅酶Ⅱ(NADPH)产量及呼吸爆发功能的变化,探讨糖尿病患者易感染的可能机制。方法检测2型糖尿病患者外周血白细胞G6PD活性、NADPH含量,并通过检测白细胞活性氧(ROS)产量观察其呼吸爆发功能,研究白细胞外不同浓度糖环境对细胞呼吸爆发功能的影响。结果与正常人比较,糖尿病患者外周血白细胞G6PD活性、NADPH产量及ROS含量均明显降低。结论血糖控制不良引起糖尿病患者白细胞内PPP途径代谢紊乱,G6PD活性下降从而导致其白细胞呼吸爆发功能障碍,这可能是糖尿病患者易于感染的主要原因之一。
