慢性阻塞性肺疾病海马1H-MRS成像研究

目的 研究慢性阻塞性肺疾病(COPD)患者海马氢质子磁共振波谱(1H-MRS)的特点.方法 随机选取32例COPD患者和30例健康志愿者分别纳入研究组和对照组.采用1H-MRS检测双侧海马的N-乙酰基天门冬氨酸(NAA)、胆碱复合物(Cho)和肌酸复合物(Cr).结果 研究组左右侧海马NAA/Cr值均显著低于对照组,差异有统计学意义(t=4.963,P=0.007和t=4.856,P=0.023);研究组左右侧海马Cho/Cr值均显著高于对照组,差异有统计学意义(t=3.469,P=0.013和t=3.019,P=0.047).结论 COPD患者存在海马神经元的代谢异常.

1H-MRS measurement of the hippocampus in chronic obstructive pulmonary disease

Objective To identify the features of 1H-magnetic resonance spectroscopy(1H-MRS) in patients with chronic obstructive pulmonary disease(COPD) of the hippocampus.Methods 32 patients with COPD randomly selected and 30 normal controls were selected.1H-MRS of the hippocampus was performed given to on all the subjects on hippocampus.The ratios of NAA/Cr and Cho/Cr were determined.Results In the bilateral hippocampus, the NAA/Cr ratio in patients with COPD demonstrated lower than that in normal controls(t=4.963,P=0.007 and t=4.856,P=0.023).The Cho/Cr ratio in patients with COPD showed higher than that in normal controls, the differences was were statistically significant(t=3.469,P=0.013 and t=3.019,P=0.047) Conclusion Abnormal metabolism of neurons on the hippocampus in patients with COPD is showed.
