| 目的：研究冠脉搭桥术后肺水肿患者氧化应激状态变化观察，评价氧化应激状态与肺水肿的关联性，为临床减轻冠脉搭桥
术后肺部并发症提供依据。方法：将本院2014年1 月-2015 年6 月收治的冠脉搭桥术后肺水肿患者40 例作为试验组，另选同期
冠脉搭桥术后未发生肺水肿患者40 例作为对照组。检测并比较两组患者术后3 天、7 天及14 天的丙二醛（MDA）、总抗氧化能力
（TAC）、过氧化氢酶（CAT）、C 反应蛋白（CRP）、过氧化脂（LPO）及超氧化物歧化酶（SOD）的水平变化。结果：与对照组患者相比，
试验组患者术后3 d、7 d、14 d三个时间点MDA，LPO 及CRP表达水平均显著提高，而TAC，SOD及CAT 表达水平均显著降低，
差异均具有统计学意义（P＜0.05）。与术后3 d相比，两组患者术后7 d、14 d两个时间点的MDA，LPO 和CRP表达水平均显著降
低，而TAC，SOD及CAT 表达水平均显著提高，差异具有统计学意义（P＜0.05）。结论：冠脉搭桥术后肺水肿的发生与患者氧化应
激状态密切相关，机体自由基增多、抗氧化能力下降是肺水肿发生的重要机制。 |

| Objective:To study the changes of oxidative stress for patients with pulmonary edema after coronary artery bypass
surgery, and evaluate the correlation of oxidative stress and pulmonary edema, so as to provide a reference for clinical research.Methods:40 cases with pulmonary edema who had taken the coronary artery bypass surgery in our hospital from January 2014 to June 2015 were
selected as the research group, and another 40 cases without pulmonary edema were chosen to be the control group. Then the level
changes of the malondiadehyde (MDA), total antioxidant capacity (TAC), catalase (CAT), C-reactive protein (CRP), lipid peroxide
(LPO) and superoxide dismutase (SOD) after the operation for 3 days, 7 days and 14 days in the two groups were detected and compared.Results:Compared with the control group, the levels of MDA, LPO and CRP in the research group were higher, and the levels of TAC,
SOD and CAT were lower after the operation for 3 days, 7 days and 14 days, and the differences were statistically significant (P<0.05).
Compared with the third day after operation, the levels of MDA, LPO and CRP were higher and the levels of TAC, SOD and CAT were
lower in the two groups after the operation for 7 days and 14 days, and the differences were statistically significant (P<0.05).Conclusion:The occurrence of pulmonary edema after coronary artery bypass surgery is closely related to patients with oxidative stress, the increase
of free radicals and the decline of antioxidant capacity is the important mechanismof pulmonary edema. |
