[ Method] Experiments were divided into 4 groups： group Ⅰ （blank control group） ; group Ⅱ （liposome group） ; group Ⅲ （SCON group： 20 μmol/L sense oligonucleotide） ; group Ⅳ （ASCON： 20 μmol/L antisense oligonucleotide）. VEGF and its receptor Fit-1 mRNA expression changes were detected by using real-time fluorescence quantitative detection after 24, 36 and 48 h. [ Result] The expression of VEGF mRNA in group Ⅰ, group Ⅱ were insignificantly different at higher expression levels, and did not change significantly with the time; the expression of VEGF mRNA in group Ⅲ assumed a slight decrease, but there were no significant differences between group I and group Ⅱ （P 〉0.05）, the expression of VEGF mRNA in group Ⅳ（antisense oligonucleotide group ） decreased significantly （P 〈 0.05） ; the expression of VEGF receptor FLT-1 mRNA was similar to that of VEGF. [ Conclusion] Antisense inhibition ghrelin has a downward effect to the expression of VEGF and its receptor Fit-1 the mRNA.展开更多
