Abstract Title:
[Effect of acupuncture on neurological function, cerebral infarction volume, thrombolysis time window and cerebral cell apoptosis signaling pathway in cerebral infarction rats].
Abstract:
OBJECTIVE: To observe the effect of acupuncture (Acupunct) on cerebral infarction volume and expression of poly ADP ribose polymerase 1 (PARP1), apoptosis-inducing factor (AIF) and endonuclease G (Endo-G) in the cerebral cortex tissue at different time-points after cerebral ischemia (CI) in acute cerebral infarction rats, so as to explore its underlying mechanisms in prolonging time window of thrombolysis.METHODS: Forty-eight SD rats were randomly divided into sham operation, model, intravenous thrombolysis (IVT)-4.5 h, IVT-6 h, IVT-9 h, Acupunct＋IVT-4.5 h, Acupunct ＋IVT-6 h, Acupunct＋IVT-9 h groups (＝6 in each group). The CI model was established by using modified autologous thromboembolism via the right common carotid artery. Two hours after modeling, rats of the Acupunct groups received Acupunct stimulation of"Shuigou"(GV26) and bilateral"Neiguan"(PC6) for 30 min. Thrombolysis was conducted by injection of recombinant human tissue-type plasminogen activator (rt-PA, 10 mg/kg) via caudal vein. The neurological deficit was assessed with reference to Bederson's methods. 2，3，5-triphenyltetrazolium chloride (TTC) staining was used to assess the cerebral infarction volume, and the expression of cerebral PARP1, AIF and Endo-G proteins detected by Western blot.RESULTS: Compared with the sham operation group, the neurological score and percentage of cerebral infarction volume, expression levels of PARP1, AIF and Endo-G proteins were significantly increased in the model group (
