摘要: 目的:观察银杏叶提取物对糖尿病肾病(DN)患者血清氧化应激及血液流变学指标的影响。方法:将DN 患者按自愿原则分为银杏叶提取物(美怡欣注射液)治疗组和对照组。观察两组治疗前后血清超氧化物歧化酶(SOD)、谷光甘肽过氧化酶(GSH-Px)、丙二醛(MDA)及血液流变学指标的变化。结果:治疗前两组SOD、GSH-Px、MDA 和血液流变学指标无明显差异。银杏叶提取物治疗后SOD、GSH-Px 较对照组明显升高,MDA 明显降低(P<0.01);尿蛋白定量较对照组明显下降(P<0.01);低切全血黏度、红细胞压积、红细胞聚集指数和血小板聚集率较对照组和同组治疗前显著下降(P<0.01), 而高切全血黏度和血浆黏度下降不明显;红细胞变形性显著增高(P<0.01)。结论:DN 患者细胞抗氧化能力明显降低;银杏叶提取物通过提高抗氧化应激能力及改善血液流变性, 减少蛋白尿对肾脏起保护作用。

Abstract: AIM: To investigate the effect of ginkgo leaf extract on oxidative stress and haemodynamics of diabetic nephropathy(DN).METHODS: The patients of DN were divided into ginkgo leaf extract treatment group and control group.The changes of serum superoxide dismutase (SOD), glutathione peroxidase(GSHPx), malondialdehyde (MDA)and hemorheology indexes were observed.RESULTS: Before treatment, serum SOD, GSH-Px, MDA and hemorheology indexes had no significant difference between ginkgo leaf extract treatment group and control group.After treatment, the serum levels of T-SOD and GSH-Px were increased; the level of MDA, hemorheology indexes, erythrocyte aggregation index and platelet aggregation rate were decreased significantly in ginkgo leaf extract treatment group compared with those in control group (P<0.01).CONCLUSION: The antioxidant ability of cells were deceased in DN.Ginkgo leaf extract could protect the renal function by increasing the activities of SOD and GSH-Px, improving the hemorheology, decreasing the albuminuria.

Key words: ginkgo leaf extract, diabetic nephropathy, oxidative stress, hemorrheology
