摘 要:目的研究静脉注射左卡尼汀对维持性血液透析(MHD)患者氧化应激及营养状态的干预作用。方法55例MHD患者随机分为对照组(A组),左卡尼汀小剂量治疗组(B组)及大剂量治疗组(C组)。治疗组除给予和对照组相同的透析治疗外,在每次透析结束时B组给予左卡尼汀1.0 g,C组则给予左卡尼汀2.0 g静脉注射,随访3个月。分别检测各组治疗前、治疗1个月及3个月末患者的血生化指标,并采用比色法测定血浆丙二醛(MDA)、谷胱甘肽过氧化物酶(GSHPx)、一氧化氮(NO)。结果A组第1、3个月时MDA较透析前增加,(4.72±0.05)nmol/L、(4.81±0.07)nmol/L vs(4.62±0.06)nmol/L(P<0.05),第3个月末时GSHPx降低,(72.02±2.05)μmol/L vs(74.62±1.46)μmol/L(P<0.05),血红蛋白(Hb)、血浆白蛋白(Alb)降低,但差异无统计学意义(P>0.05)。B组在第1、3个月时MDA明显低于A组,(4.29±0.09)nmol/L vs(4.72±0.05)nmol/L;(3.86±0.06)nmol/L vs(4.81±0.07)nmol/L(P<0.01),GSHPx、NO则显著增高,(83.49±0.93)μmol/L vs(73.55±0.51)μmol/L,(92.11±1.62)μmol/L vs(72.02±2.05)μmol/L,(60.26±0.99μmol/L vs(52.82±1.30)μmol/L,(64.24±1.72)μmol/L vs(49.91±1.19)μmol/L(P<0.05);在第3个月时,患者的Hb,Alb水平较治疗前显著升高,(94.74±1.64)g/L vs(86.96±4.16)g/L,(40.25±0.89)g/L vs(37.66±0.46)g/L(P<0.05);C组效果优于B组(P<0.05)。结论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,可能有延缓血管粥样硬化的作用,且以大剂量效果为好。Objective To research the role of the intervention of intravenous levocarnitine in the impact of oxidative stress of patients with maintenance hemodialysis(MHD). Methods Fifty-flve patients with MHD more than half a year were randomized to control group (group A), treatment group with low-dose levocarnitine (group B), or with high-dose levocarnitine (group C). 1.0 g and 2.0 g intravenous levocarnitine were administered to group B and C at the end of dialysis respectively besides the dialysis treatment which was also given to control group. The patients were followed up for three months. The blood biochemical indicators of each group were measured respectively before treatment,at the end of 1st and 3rd month. At the same time,malondialdehyde(MDA) ,glutathione peroxidase(GSHPx) and nitricoxide(NO) expression were mensurated with colorimetry. Results MDA of group A increased compared with that of pre-dialysis at the end of the 1 st and 3rd month, (4.72 ±0. 05) nmol/L, (4.81± 0. 07) 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〉0.05). Hemoglobin(Hb) and blood albumin(Alb) reduced without statistical significance ( P 〉0.05). In group B,MDA declined more comparing with group A, (4.29±0.09) nmol/L vs (4. 72±0.05) nmol/L; (3.86±0.06) nmol/L vs (4.81±0.07) nmol/L( P d0.01) ,while GSHPx and NO increased significantly, (83.49±0.93) μmol/L vs (73.55±0.51) μmol/L; (92.11± 1.62) μmol/L vs (72.02±2.05) μmol/L;(60.26±0.99) μmol/L vs (52. 82±1.30) μmol/L;(64. 244±1.72) μmol/L vs (49.91 ±1. 19) μmol/L( P 〈0.05). In the 3rd month, Hb and Alb level rose obviously,(94. 74±1.64) g/L vs (86. 96±4.16) g/L;(40. 25±0.89) g/L vs (37. 66±0. 46) g/L( P〈0. 05) Group C was better in treatment effect than group B( P〈0.05). Conclusion Levoearnitine effectively improves
