Objective To observe the effect of electroacupuncture (EA) plus oxygenmedicine (OM) on the expression of Bcl-2 and Bax in the hippocampal CA 1 area in cerebral ischemia/reperfusion injury (CI/RI) rats. Methods Thirty SD rats were randomized into sham-operation,model,EA,OM,EA+OM groups (n=6/group). CI/RI model was established by using modified Pulsinelli 4 vessel occlusion and reperfusion. EA (100 Hz,3.5 mA) was applied to "Baihui" (GV 20) and "Zusanli" (ST 36) 30 min,once daily for 4 days. Rats of OM and EA+OM groups were put into a box filled with oxygen and atomized herbal medicines containing Bingpian (Borneolum),Shexiang (Moschus),Huangjing (Rhizoma Polygonati),Shouwu (Radix Polygoni Multiflori),etc. for 30 min,once daily for 4 days. Bcl-2 and Bax expression of the hippocampal CA 1 area was detected by immunohistochemistry. Results Compared with sham group,the numbers of Bcl-2 immunoreaction (IR) and Bax IR positive cells,and the immunoactivity of Bcl-2 IR and Bax IR positive products in the hippocampal CA 1 area were increased significantly in model group (P0.05). Conclusion EA and OM and EA+OM can effectively regulate the expression of Bcl-2 and Bax in the hippocampal CA 1 area in CI/RI rats,and the effects of EA+OM are significantly superior to those of simple EA and simple OM,which may contribute to their effect in improving cerebral ischemia.

To achieve higher level expression of Interferon α2b (IFN-α2b) in methylotrophic yeast (Pichia pastoris), a cDNA fragment coding for the mature IFN-α2b was designed and synthesized based on the synonymous codon bias of P. pastoris and optimized G+C content. The synthetic IFN-α2b was inserted into the secreted expression vector pPICZαA, and then integrated into P. pastoris GS115 genome by electroporation. Multi-copy integrants in the Mut+ recombinant P. pastoris strain were screened by high concentrations of Zeocin. 120 hours culturing allowed expression of the IFN-α2b transformant up to 810 mg/L as detected by SDS-PAGE and quantitative methods. In addition, Western blot analysis showed that the recombinant proteins had immunogenicity. The significant antiviral activity of the recombinant IFN-α2b protein was verified by WISH/ VSV system, which was 3.3×105 IU/mL.
