BACKGROUND: To study the factors of the Sonic Hedgehog (Shh) signaling pathway after permanent cerebral ischemic and the effects by acupuncture. METHODS: Male Wistar rats were divided into Electro-acupuncture (EA) group, Model Control (MC) group, and blank control (Control) group. EA and MC were divided into 9 phases, namely 1 h, 3 h, 6 h, 9 h, 12 h, 24 h, 3 d, 7 d, and 12 d after the operation. The neurological deficits and permanent cerebral ischemic volume were observed. The immunofluorescence method was used to examine the angiogenesis. (Polymerase Chain Reaction) PCR and (Immunohistochemistry) IHC were used to test the changes in Shh, Ptch, Smo, and Gli2 mRNA and proteins. RESULTS: The neurological severity scores (NSS) of the Control was 0, the score of the EA group was less than that of the MC. The cerebral permanent ischemic volume of the Control was 0 %, and the EA group's was smaller than that of the MC. The expression of copositive cells in the EA group was higher than the MC's from 12 h to 12 d, and the EA group had more peripheral blood vessels. The rat brain expressions of Shh, Ptch, Smo and Gli2 mRNA and proteins in the MC was higher than that of the Control, the rat brain expression of the EA group was higher than that of the MC. CONCLUSIONS: EA can upregulate the expression of the Shh signaling pathway factors, thereby promoting angiogenesis."
