Since the new biology course standards implemented, a series of deep changes have taken place in education and teaching at school. After one month's teaching practice, I found the big challenge in activizing students' initiative is to teachers. Especially, the choice of biology task and experiment lessons are seem particularly important.

Methods In situ hybridization and immunohistochemistry were used respectively to detect mRNAs and proteins in 47 cases of esophageal squamous cell carcinoma and their correspondent para-cancerous mucosae, distal cuts.

目的：研究EGR-1 、c-fos 、cyclin D1 3种基因mRNA及其相应蛋白在人食管癌癌变过程中的表达水平及其相关性，并探讨其与食管癌的发生、发展及生物学行为的关系。

It infested one to two generations in one year in Changsha, and overwintered through adults. They spend 48.2 days in finishing a complete generation under the temperature of 25±1℃, and the development time of eggs, larvae, pupas and adults were 7, 10, 10 and 30 days respectively.

通过室内饲养和野外观察，研究了该虫的生物学特性：在长沙地区1年发生1~2代，以成虫越冬，幼虫在25±1℃温度条件下，完成一个世代的历期为48.2d，卵期7d，幼虫期30d，蛹期10d，成虫期30d左右。

Pallidifascia were studied by indoor and outdoor trials. The results showed that the pest developed 4 generations a year and overwintered with larvae in Guangzhou, Guangdong province of China. The larva stage included 7 instars. It appeared sexual dimorphism on the adults. The egg, larva and pupa stages lasted 4-5 days, 32-34 days and 9-11 days at 26℃ respectively.
