摘要
To explore the effects of acupuncture at Baihui (GV 20) and Zusanli (ST 36) on the peripheral serum expression of microRNA 124 (miRNA 124)
laminin and integrin β1 in rats with cerebral ischemia reperfusion injury (CIRI). Seventy-two healthy male Sprague-Dawley rats were randomized into a model group
an acupuncture group
and a sham-operated group using a random digits table
with 24 rats per group. Each group was further randomly divided into 1-
3-
5-
and 7-day subgroups based on the reperfusion time according to a random digits table
with 6 rats in each subgroup. In the model and acupuncture groups
CIRI was induced using the thread occlusion method. Electroacupuncture stimulation was applied daily to GV 20 and left ST 36 for 20 min at the indicated time points after successful operations. Serum was sampled for detecting laminin and integrin β1 protein via enzyme-linked immunosorbent assay
and serum miRNA 124 was examined using quantitative polymerase chain reaction. The serum level of miRNA 124 in the cerebral ischemia rats increased significantly
and the peak expression of miRNA 124 in both the model and acupuncture groups occurred at 3 days. The expression of miRNA 124 in the acupuncture group was higher than in the model group at the same time point (5.96±0.01 vs. 3.11±0.04
P <0.05). Laminin expression in serum from the cerebral ischemia group was higher than that in the sham-operated group. Compared with the model group
the level of laminin in the serum of the acupuncture group was significantly lower at each time point
especially at the 3-day
and 7-day time points (589.12±3.57 vs. 793.05±5.28
and 600.53±3.05 vs. 899.06±5.74
P <0.05). The level of integrin β1 in the serum from the acupuncture group was lower than that in the model group particularly at the 3-day and 7-day time points (208.66±0.95 vs. 280.83±1.77
and 212.36±0.95 vs. 316.77±2.42
P <0.05). Additionally
the model group and the acupuncture group showed dual peaks of integrin β1 and laminin expression at 3-day and 7-day. Acupuncture at GV 20 and ST 36 in rats alleviated CIRI and was associated with upregulated expression of miRNA 124 and with downregulated expression of integrin β1 and laminin in peripheral serum. These changes may represent one of the mechanisms underlying acupuncture’s attenuation of CIRI.
