There were 8 embryos single blastomere amplified, and the amplification success rate was 72. 7%(8/11); 3 embryos' not amplified; 2 embryos'showed preferential amplification , and the PA rate was 25%(2/8); and the 7 tubes of blank with washing cell solution were not contaminated. We transferred 3 unaffected embryos to the uterus. But unfortunately, blood hCG was negative after 2 weeks of transferring indicating no pregnancy.

共8枚胚胎的单卵裂球得到扩增，扩增成功率为72.7%（8/11），3枚未得到扩增，2枚发生了偏性扩增(preferentialamplification，PA)，PA的发生率为25%（2/8），细胞洗脱液空白对照7管均无污染发生。3枚诊断为正常的胚胎被移植入宫内，不幸的是，移植后2周，血hCG阴性，证明未妊娠。

We hypothesize that Zfp474 functions as a germ cell specific transcription factor that plays important roles in spermatid differentiation and oocyte development.

结果提示：Zfp474基因对精子发生和卵母细胞的发育可能起重要作用。

In Xinxiang Aera of Henan Province in 1997, the occurrence of cotton pests were investigated in the Bt cotton and common cotton fields The result showed that the numbers of cotton bollworm egg were similarly in both fields, but that of survival larvae on Bt cotton were lower than that on common cotton The occurrence of cotton aphis was no difference but the spider mite were more heavy in Bt cotton field At the same time,control strategy against cotton pests were discussed for the Bt cotton

对河南新乡棉区种植的转Bt基因棉和常规棉棉田虫情进行了定点系统调查和大田普查，结果表明：棉铃虫在两种棉田棉花上的落卵量无明显差别，而幼虫存量差异显著，Bt棉棉花上幼虫存量显著降低；Bt棉对棉蚜的发生无明显的影响，而Bt棉上棉红蜘蛛的发生比常规棉略重，同时初步研究制定出种植Bt棉后的棉虫综防对策
