The study on the total oxidative and antioxidant status and lipid levels in patients with COPD / 实用医学杂志

ABSTRACT

Objective To explore and evaluate the total oxidative and antioxidant status and lipid levels in patients with COPD. Methods Measurement and comparative analysis were preformed between 51 cases of COPD patients and 45 healthy people in serum TOS,TAS,IMA concentration,blood lipid,and the concentration of ox-LDL. Results In the COPD group,serum IMA concentration was significantly higher than those in the control group(0.94 ± 0.31 vs. 0.62 ± 0.25,P<0.001). The serum TOS was higher than that in the control group(6.51 ± 4.85 vs. 4.53 ± 3.81,P<0.05). The serum ox-LDL concentration in COPD group increased significantly compared with the control group(5.91 ± 3.61 vs. 4.51 ± 2.05,P<0.05). The serum HDL concentration in the COPD group was significantly lower than that in the control group(36.49 ± 9.60 vs. 44.19 ± 10.14,P<0.001). There was no sig-nificant difference in TAS,triglyceride and low LDL between the two groups. Conclusions The serum levels of TOS,ox-LDL and IMA are significantly increased in COPD patients compared with the control group,while HDL-C concentration is significantly decreased. Increase of IMA and ox-LDL in serum of patients with COPD may be relat-ed to imbalance of TOS and TAS due to chronic inflammation and oxidative stress.
