Objective To investigate effect of serum apoptosis factor and long-term effect on medical abortion patients by sequential misoprostol. Methods 80 cases of early pregnancy patients who required termination pregnancy, were selected and randomly divided into 2 groups.40 cases in control group were treated with mifepristone 25mg oral, misoprostol 600μg, 4 times a day.40 cases in experiment group were treated with sequential use of misoprostol.Effect of medical abortion, survivin and caspase-3 were compared after 7d treatment.Gynecological inflammation, dysmenorrhea and infertility were compared for 2 years.Results Compared with control group, complete abortion rate of the experiment group was higher (P<0.05).The incidence of adverse drug reactions of the experiment group was lower than control group (P<0.05) after 2 years follow.up.Compared with the control group, HCG,E3 and P of experimental group were lower (P<0.05).After 7 days of medication,survivin decreased,caspase-3 increased,compared with control group, survivin of the experiment group was lower, caspase-3 was higher ( P<0.05 ) .Conclusion Misoprostol sequential can improve the success rate of medical abortion abortion, reduce the complications of abortion, presumably with the inhibition of survivin expression, is associated up regulation of caspase-3 levels.

From April 2009 onward, a new strain of human H1N1 influenza virus has swept over the world. The genome of influenza virus consists of 8 segments, encoding 10 proteins, respectively. The reassortments among the 8 segments cause the variation of influenza virus. Therefore, phylogenetic analysis of the 8 genes is very important. In this paper, we choose neighboring word frequency as the genomic features, using VC++ programming to analyze evolution of the 8 segments of H1N1 virus. As a result, we found that PB2 genes and PA genes of these three isolated virus were originated from North American avian influenza virus, that PB1 genes were originated from the seasonal influenza virus of human, and that HA genes, NS genes and NP genes came from the North American classical swine influenza A virus. The NA segments and M segments were originated from the European swine influenza virus.
