大剂量维生素C预冲透析器联合维生素E和丹参对血液透析患者晚期氧化蛋白产物的影响

60例血液透析半年以上的尿毒症患者随机分为A组（常规透析组）、B组（透析加口服维生素E、丹参组）、C组（透析加大剂量维生素C预冲透析器联合维生素E、丹参组），正常对照组20例。分别在第0、1、2、3个月检测血浆氧化应激指标晚期氧化蛋白产物（AOPP）和超氧化物歧化酶（SOD）。A、B、C三组血浆AOPP含量均明显高于正常对照组（P〈0．01），SOD含量则低于正常对照组（P〈0．01）。与A组同时间点比较，B、C组AOPP也明显降低（P〈0．01），SOD明显升高（P〈0．01）。与B组同时间点比较，C组AOPP也明显降低（P〈0．01），SOD明显升高（P〈0．01）。应用大剂量维生素C预处理透析器膜联合维生素E，丹参口服能减轻血液透析患者体内的氧化应激。

Pretreatment of dialyzer with high-dose vitamin C reduces oxidative stress of patients withhemodialysis

Sixty patients who had hemodialysis over half year were randomly divided into 3 groups with 20 cases in each group:group A received conventional hemodialysis,group B received hemodialysis with oral administration of compound danshen (salvia miltiorrhiza bunge) tablets and vitamin E,group C had the same treatment as group B but the dialyzer was pretreated with solution containing 5 g vitamin C ; 20 healthy adults served as normal controls. Serum levels of advanced oxidation protein products (AOPP) and superoxide dismutase (SOD) were measured in all groups.The levels of AOPP in groups A,B,C were higher and SOD levels were lower than those of normal controls ( all P ＜ 0.01 ).The levels of AOPP in groups B,C were lower and SOD were higher than those in group A at the same time points (P ＜0.01 ).The levels of AOPP in group C were lower and SOD were higher than those in group B at the same time points (P ＜0.0l ).The results suggest that pretreatment of the dialyzer with high dose vitamin C plus vitamin E and compound danshen tablets can alleviate oxidative stress in patients with maintaining hemodialysis.
