摘要:

目的 探讨同型半胱氨酸(Hcy)与炎症反应及氧化应激的相关性,分析其在急性缺血性脑卒中(AIS)发生发展中的作用。 方法 选取首次发病的38例AIS患者作为AIS组,并按照病例对照研究原则,选取同期体验的健康体验者45名作为对照组。采用酶联免疫吸附试验(ELISA)检测2组研究对象血清中Hcy水平和炎症因子白细胞介素(IL)-6及肿瘤坏死因子α(TNF-α)水平,免疫比浊法检测2组研究对象血清中超敏C反应蛋白(hs-CRP)水平,化学比色法检测2组研究对象血清中丙二醛(MDA)水平和超氧化物歧化酶(SOD)活性。采用Pearson相关分析法分析AIS患者血清Hcy水平与炎症因子及氧化应激指标水平的相关性。 结果 与对照组比较,AIS组患者血清中Hcy、hs-CRP、TNF-α、IL-6和MDA水平均明显升高(P<0.05),SOD活性明显降低(P<0.05)。AIS患者血清Hcy水平与hs-CRP、TNF-a、IL-6和MDA水平呈正相关关系(r=0.615,P<0.05;r=0.632,P<0.05;r=0.598,P<0.05;r=0.612,P<0.05),与SOD活性呈负相关关系(r=-0.325,P<0.05)。 结论 AIS患者血清中Hcy水平与炎症因子及氧化损伤有密切关联。Hcy能够促进氧化自由基及炎症因子产生,并对内皮细胞造成损伤,在AIS发生发展过程中具有一定临床意义。

Abstract:

Objective To discuss the correlation between homocysteine (Hcy) and inflammatory responses as well as oxidative stress, and to analyze its role in the occurrence and development of acute ischemic stroke (AIS). Methods Thirty-eight patients with their first incidence of AIS were selected as AIS group, and according to the principles of case-control study, 45 healthy individuals undergwent routine health examination during the same period were selected as control group. The levels of homocysteine and inflammatory cytokine interleukin (IL)-6, and tumor necrosis factor α (TNF-α) in serum of the subjects in two groups were detected by enzyme-linked immunosorbent assay (ELISA) method; the level of highly sensitive C-reactive protein (hs-CRP) of the subjects in two groups was detected by immunoturbidimetry; the levels of malondialdehyde (MDA) and activities of superoxide dismutase (SOD) in serum of the subjects in two groups were detected by chemical colorimetry; Pearson’s correlation analysis was used to analyze the correlation between serum Hcy level and levels of inflammatory markers and oxidative stress indicators of the AIS patients. Results Compared with control group, the levels of Hcy, hs-CRP, TNF-α, IL-6, and MDA in serum of the patients in AIS group were significantly increased (P<0.05), while the activity of SOD was significantly decreased (P<0.05). The level of Hcy in serum of the AIS patients was positively correlated with the levels of hs-CRP, TNF-α, IL-6, and MDA (r=0.615, P<0.05; r=0.632, P<0.05; r=0.598, P<0.05; r=0.612, P<0.05), and negatively correlated with the activity of SOD (r=-0.325, P<0.05). Conclusion The Hcy level in serum of the AIS patients is closely associated with the inflammatory factors and oxidative damage. Hcy can promote the production of oxidative free radicals and inflammatory factors and cause damage to the endothelial cells and play a significant clinical role in the occurrence and development of AIS.
