Effects of Yangxueqingnao granule on inflammatory factor expressions and axonal regeneration in rats with focal cerebral ischemia reperfusion
Objective:To investigate the effects of Yangxueqingnao granule on expressions of nuclear factor-κBp65(NF-κBp65),in-terleukin-6(IL-6) and neurofilament protein-200(NF-200) in cortex and neurological function after focal cerebral ischemia reperfu-sion injury in rats. Methods:Seventy-two SD rats were randomly divided into sham-operated group(S group),cerebral ischemia/reperfusion group(I/R group),normal saline control group(I/R+C group) and Yangxueqingnao granule treated group(I/R+YXQ group). Neurological function was measured using Montoya staircase test. Changes in expressions of NF-κBp65 and IL-6 were analyzed by immunohistochemistry and Western blot,respectively. NF-200 immunohistochemical staining was used to evaluate axonal regener-ation. Results:At the 2nd d after ischemia reperfusion,expressions of NF-κBp65 and IL-6 in ischemic cortex were significantly in-creased(P<0.001),while those of NF-200 were significantly decreased in I/R group(P<0.001). Expressions of NF-κBp65 and IL-6 were lower in IR+YXQ group than in I/R group(P<0.001). At the 2nd week after ischemia reperfusion,expressions of NF-200 positive cells in I/R+YXQ group were increased compared with those in the I/R group(P<0.001) and behavioral tests showed no difference in neurological improvement(P=0.178). Conclusions:Yangxueqingnao granule can improve neurological function recovery after focal cerebral ischemic reperfusion injury in rats,which may be associated with the inhibition of inflammation reactions.
