Conclusions Application of ECS can obviously improve the training effect of CPR and it can be widely popularized in the edu-cation and training of emergency medicine skills.

Objective To investigate the effect of HIF-2a silencing by transfection of siRNA into MG-63 cells un-der hypoxia. Methods HIF-2αexpression level in MG-63 cells under hypoxia was determined by Western Blot. Small in-terfering RNA (siRNA) was used to construct MG-63/siHIF-2α(siHIF-2α)cells and control MG-63/scramble (NC) cells. The expression levels of HIF-2α, Vascular endothelial growth factor (VEGF), p-Erk/ErK and Mcl-1 in MG-63, NC and si-HIF-2αcells was determined by Western Blot. NC and siHIF-2αcells were cultured under hypoxia. Cell viability was as-sessed by MTT assay. Migration was identified by scratch migration assay. Tumor formation was identified by clone formation assay. Nude mouse subcutaneous xenograft model was used to investigate tumor development in vivo. Results Hypoxia im-proved HIF-2αexpression in MG-63 cells in a time-dependent manner (F=2 037.412,P<0.001). HIF-2αexpression un-der hypoxia in siHIF-2αcells was lower than that in NC cells (P<0.01). Cell viability of siHIF-2αcells under hypoxia for 12 h and 24 h were lower than that in NC cells (P<0.05 or P<0.01). The relative width of scratch in siHIF-2αgroup under hypoxia for 12 h and 24 h were larger than that in NC group (P<0.01 or P<0.01). When cell counts reach 1 000-5 000, the clone formation rates of siHIF-2αcells were lower than that in NC cells (P<0.05 or P<0.01). The expression of VEGF, p-Erk/Erk and Mcl-1 protein under hypoxia in siHIF-2αcells was lower than that in NC cells(P<0.01). Tumor sizes, weights and density of siHIF-2α group in nude mice were suppressed compared with those in NC group (P<0.01). Conclusion Blocking HIF-2αsignal pathway warrants its investigation as a potential strategy in osteosarcoma treatment.

Objective Bone marrow mesenchymal stem cells ( BMSCs) , a kind of stem cells with multiple differentiation po-tentials, exist in the bone marrow and other organizations.This study aimed to investigate the repairing effect of the exogenous basic fi-broblast growth factor ( bFGF) against chronic obstructive pulmonary disease ( COPD) and its action mechanism, and to determine the expression of the bFGF gene in transfected rat BMSCs. Methods BMSCs were isolated, cultured and identified.The recombinant plasmid bFGF-pcDNA3.1 was constructed and sequenced.Liposome-mediated bFGF-pcDNA3.1 plasmid was transfected into the BM-SCs of the rat (bFGF-pcDNA3.1 transfection group), liposome-mediated pcDNA3.1 transfected into the BMSCs (pcDNA3.1 transfec-tion group) , and untransfected BMSCs used as the control.G418 screening was performed for 14 days.The gene and protein expres-sions of bFGF were determined by qRT-PCR and Western blot. Results The full-length sequence of the bFGF gene was consistent with that of the GenBank.The expression of the bFGF gene was significantly higher in the bFGF-pcDNA3.1 transfection group (7.028 ±0.568) than in the pcDNA3.1 transfection group (1.000 ±0.082) and the non-transfection control (1) (P<0.01), but with no statistically significant difference between the latter two groups (P>0.05).The expression of the bFGF protein was also re-markably higher in the bFGF-pcDNA3.1 transfection group (1.017 ±0.054) than in the pcDNA3.1 transfection group (0.217 ± 0.009) and the non-transfection control (0.165 ±0.013) (P<0.05), with no statistically significant difference between the latter two groups (P>0.05). Conclusion Mediated by the liposome reagent, the recombinant eukaryotic expression vector bFGF-pcD-NA3.1 can be transfected into rat BMSCs and expresses the bFGF gene and protein.

Objective To study the influence of bFGF gene transfected bone marrow-derived mesenchymal stem cells (BMSCs) on the inflammatory cytokines of COPD rat. Methods The BMSCs were separated from SD rat and cultured and then bFGF gene was imported to BMSCs by liposome transfection method. The samples were prepared into six groups: normal control group, COPD group (A), BMSCs group (B), pcDNA3.1-BMSCs group (C), bFGF-pcDNA3.1-BMSCs group (D), and bFGF group (E). The expressions of TNF-α and IL-1β by QRT-PCR were detected. Results Compared with COPD group, TNF-α and IL-1β genes from groups B to D dropped significantly (P < 0.05). The changes of TNF-α and IL-1β genes among groups B to D showed no significant difference (P > 0.05). Conclusion BFGF transfected BMSCs, sample BMSCs and pcDNA3.1 transfected BMSCs can inhibit the expression of inflammatory cytokines of TNF-α and IL-1β, but there is no obvious advantage in comparison to bFGF transfected BMSCs and sample BMSCs in respect of inhibiting the expression of inflammatory cytokines of TNF-α and IL-1β.
