To observe the effect of acupuncture on the cerebral infarct volume and expressions of Beclin1, microtubule-associated protein 1 light chain 3 (LC3) and p62 proteins related to cell autophagy in rats with cerebral ischemia (CI), so as to explore its mechanisms underlying improvement of CI injury.Male SD rats were randomized into 3 groups: sham operation, model and acupuncture which were further divided into 4 subgroups according to different ischemia time-points: 3, 6, 12 and 24 h (Compared with those of the sham operation group，the neurological deficit scores at 2, 3, 6， 12 and 24 h after CI, and the infarct volumes, the expression levels of Beclin1 and the ratios of LC3-Ⅱ/LC3-Ⅰ at 3, 6, 12 and 24 h were considerably increased (Acupuncture stimulation of GV26 and PC6 can reduce the CI volume and improve neurological function in CI rats， which may be related to its efficacy in down-regulating the expression of Beclin1 and the ratio of LC3-Ⅱ/LC3-Ⅰ, and up-regulating the expression of p62 in the ischemic brain tissue， thereby improving autophagy flux. |
