目的探讨新疆和田地区维吾尔族农村老年慢性阻塞性肺疾病(COPD)稳定期患者与非COPD者血清微量元素铜、铁、锌的含量及其相关性。方法 COPD组150例和非COPD组150例,以火焰原子吸收光谱法测定其血清铜、铁、锌的含量,并对比分析其相关性。结果 COPD组血清锌的含量与非COPD组间差异有统计学意义(P<0.05)。两组血清铜和铁、铁和锌的含量均呈负相关。结论 COPD稳定期患者与非COPD者血清铜、铁、锌含量有差异,COPD组血清锌明显低于非COPD组。
Objective To investigate the contents and correlations of serum trace elements copper, iron and zinc in the stable and chronic obstructive pulmonary disease (COPD) patients and non-COPD patients in Hetian area, Xinjiang Uygur Autonomous Region. Methods 150 cases of COPD group and 150 cases of non-COPD group were determined by flame atomic absorption spectrometry of serum copper, iron, zinc content, and comparative analysis of its correlation. Results The serum zinc level in COPD group was significantly different from that in non-COPD group (P <0.05). The levels of serum copper and iron, iron and zinc in both groups were negatively correlated. Conclusions There is a difference in serum copper, iron and zinc contents between stable COPD patients and non-COPD patients, and serum zinc in COPD patients is significantly lower than that in non-COPD patients.
