摘  要:目的研究维生素E联合左卡尼汀对维持血液透析(MHD)患者氧化应激、内皮细胞功能及营养状态的干预作用。方法83例MHD患者随机分为对照组(A组),左卡尼汀治疗组(B组),维生素E治疗组(C组),两药联用治疗组(D组)。在每次透析结束时B组给予静脉注射左卡尼汀1.0g,C组每日给予口服维生素E400mg,D组联合使用左卡尼汀和维生素E。分别检测各组患者的血生化指标及血浆丙二醛(MDA)、谷胱甘肽过氧化物酶(GSHPx)、一氧化氮(NO)。结果A组3个月末时MDA较透析前增加[(4.81±0.08)nmol/L与(4.62±0.06)nmol/L(P〈0.05)],第3个月末时GSHPx降低[(72.02±2.05)μmol/L与(74.62±1.46)μmol/L(P〈0.01)],血红蛋白(Hb)、血白蛋白(A1b)降低,但差异均无统计学意义(P均〉0.05)。B、C组在3个月时MDA明显低于A组[(3.86±0.06)、(3.81±0.19)nmol/L对(4.81±0.08)nmo]/L(P均〈0.01)],而GSHPx、NO则显著增高[(92.11±1.62)、(92.14±1.37)μmol/L对(72.02±2.05)μmol/L;(64.24±1.72)、(64.35±1.67)μmol/L对(49.91±1.19)μmol/L(P均〈0.05)]。在第3个月时,患者的Hb、A1b水平较治疗前显著升高(P均〈0.05)。D组效果优于B、C组(P均〈0.01)。结论维生素E和左卡尼汀能有效地改善MHD患者的氧化应激和营养状态,改善内皮细胞功能,且以联合用药效果好。Objective To study the treatment effects of intravenous levocarnitine in combinatan with vitamin-E in the oxidative stress state, endothelial cell function and nutritional status of patients with maintenance hemodialysis (MHD). Methods 83 patients with MHD were randomized to the control group (Group A), and three treatment groups: with levocarnitine (Group B ), with Vitamin-E (Group C ) , with levocarnitine and Vitamin-E (Group D). Intravenous 1.0 g levocarnitine were administered to Group B, oral vitamin-E (200 mg, two times each day) to group C, and vitamin-E and levocarnitine were coadministratered to group D at the end of dialysis. The blood biochemical indicators of each group were measured respectively. At the same time, malondialdehyde (MDA), glutathione peroxidase (GSHPx) and nitricoxide (NO) expression were mesured. Results MDA of group A increased compared with pre-dialysis at the end of the 3rd month [ ( 4.81 ± 0.08 ) nmol/L vs ( 4.62 ± 0.06 ) nmoL/L ( P 〈 0. 05) ], and GSHPx declined at the end of the 3rd month [ ( 72.02 ± 2.05 ) μmol/L vs ( 74.62 ± 1.46 ) μmol/L ( P 〈 0.01 ) ] Hemoglobin ( Hb ), and blood albumin ( Alb ) reduced without statistical signifiean ( P 〉 0. 05 ) ; In group B and C,MDA declined more compared with Group A[ (3.86 ± 0.06) nmol/L, (3.81 ± 0. 19) nmol/L vs (4.81 ±0.08) nmol/L, (P 〈0.01 ) ] ,while the GSHPx and NO increased significantly[ (92.11 ± 1.62) μmol/L, (92.14 ± 1.37) μmol/L vs (72.02 ± 2.05) μmol/L; (64.24 ± 1.72) μmol/L, (64. 35 ± 1. 67) μmol/L vs (49.91 ± 1.19 ) μmol/L ( P 〈 0.05 ) ]. In the 3rd month, Hb and Alb level rised obviously( P 〈 0.05 ) ; Group D was better than Group B and C (P 〈 0. 01 ). Conclusions Levoearnitine and Vitamin-E effectively improve oxidative stress and nutrition status and the function of endothelial cells of the MHD patients. It probably slows atherosclerosis progress. Furthermore, t
