基于氧化應(yīng)激及炎癥反應(yīng)探討尺澤穴位注射NS對COPD大鼠的作用機(jī)制摘要

目的：探討尺澤穴位注射NS（尼索地平）對COPD大鼠的作用機(jī)制，為COPD的治療提供新的思路和理論支持。

方法：采用煙霧暴露法建立COPD大鼠模型，將大鼠隨機(jī)分為4組，分別為對照組、COPD組、NS組和尺澤組，觀察各組大鼠的肺功能、血氧飽和度、血液指標(biāo)、氧化應(yīng)激反應(yīng)和炎癥反應(yīng)等指標(biāo)的變化情況。

結(jié)果：與對照組相比，COPD組大鼠的肺功能和血氧飽和度明顯下降，血液指標(biāo)、氧化應(yīng)激反應(yīng)和炎癥反應(yīng)等指標(biāo)明顯升高；與COPD組相比，NS組和尺澤組大鼠的肺功能和血氧飽和度明顯提高，血液指標(biāo)、氧化應(yīng)激反應(yīng)和炎癥反應(yīng)等指標(biāo)明顯降低。尤其是尺澤組的治療效果最佳，比NS組進(jìn)一步降低了氧化應(yīng)激反應(yīng)和炎癥反應(yīng)等指標(biāo)。

結(jié)論：尺澤穴位注射NS可顯著改善COPD大鼠的肺功能和血氧飽和度，降低氧化應(yīng)激反應(yīng)和炎癥反應(yīng)等指標(biāo)，具有一定的治療作用，其機(jī)制可能與調(diào)節(jié)氧化應(yīng)激和炎癥反應(yīng)有關(guān)。

關(guān)鍵詞：COPD、NS、尺澤穴位、氧化應(yīng)激、炎癥反應(yīng)
