During the war, the human rights of Chinese people were completely violated by the Japanese aggressors, causing an unprecedented human rights catastrophe. At the same time, Chinese people vigorously resisted the aggression in order to defend the national survival right and safeguard the human peace against war. The history of human rights’ victory over human rights abuses tells us: aggressive wars are the most serious violations of human rights. We must protect people’s right to peace for every country in the world. In order to avoid violations of human rights by war once again, we must safeguard the international postwar order and prevent the revival of fascism, whose essences are contempt for and trample on human rights. Therefore we have to respect and protect human rights and defend both the collective rights of every nation and the individual rights of every person in the world.展开更多

Meanwhile, the total RNA of virus gene was extracted and amplified by RT-PCR with the designed primers, and then it was purified and cloned to the expression vector pGEM-T. The recombinant plasmid was purified and sequenced. It was found that the loss of viral titer of vaccines stored in -20℃ for longer than 10 years was less than 0.5 Lg PFU/ml. No mice inoculated intracerebrally showed signs of illness or even death. The size of plagues of the vaccine virus remained to be small, and the E genes of primary virus seed SA14-14-2 and the vaccines prepared at different years (1987-2001) were unchanged, in- cluding the 8 critical amino acid sites which were different from the parent wild virus strain SA14 and the related neuro-virulence. These results indicate that the genotypic and biological characteristics of the attenuated JE virus strain SA14-14-2 and its vaccines sion noted. prepared are quite stable without any reversion noted.展开更多
