To investigate whether the expression of cdc2 and cyclin B1 in spermatogenic cells during spermatogenesis is actually a temperature dependent event, in situ hybridization, Western blotting and immunohistochemistry analysis were used to study the expression of cdc2 and cyclin B1 in normal and cryptorchid testis. Results showed that heat would differentially hurt male germ cells in different developmental stages during spermatogenesis, especially the pachytene primary spermatocytes. Most of spermatogonia in contralateral cryptorchid testis were not harmed fatally by heat as yet, indicating that spermatogonia could resist to beat to a certain extent. In this case spermatogonia could develop to pachytene/diplotene primary spermatocytes, but they could not acquire the ability to complete the transition from mitosis to meiosis, and then appeared to go through apoptosis. Therefore, we could not find the descendants of meiosis: secondary spermatocytes and round spermatids, elongated spermatids and spermatozoon. The abdominal temperature had no significant influence on the transcription of cdc2 and cyclin B1 in the spermatogonia and pachytene/diplotene primary spermatocytes. In normal rabbit testis, cyclin B1 increased in the pachytene/diplotene primary spermatocytes before meiosis and reached its peak in the spermatids.

为了解精子正常发生过程中cdc2和cyclin B1表达的低温依赖性，我们利用原位杂交和免疫组化等方法，研究了正常和隐睾精子发生过程中cdc2和cyclin B1的转录和翻译调控活动，结果表明：（1）热对各阶段的雄性生殖细胞都有损害，粗线期的初级精母细胞尤为敏感，实验性隐睾内的精原细胞尚未完全受到"致命"影响，说明精原细胞对热有一定的耐受性，但即使成为粗线期／双线期初级精母细胞，却未能获得由有丝分裂过渡到减数分裂的能力，呈现不同程度的凋亡，所以在整个切片中找不到源自减数分裂的产物----次级精母细胞、圆形精子细胞，更谈不上长形精子细胞和精子的形成；（2）腹腔高温未明显地影响隐睾精原细胞和粗线期/双线期初级精母细胞中cyclinB1和cdc2的转录，说明高温并不是通过影响cyclin B1和cdc2的转录活动而导致生精过程阻断的；（3）正常兔睾丸组织中，〓在精原细胞和粗线期／双线期精母细胞中均有表达：cyclin B1蛋白在减数分裂前期的粗线期／双线期初级精母细胞中的表达量增加，于变态末期的精子细胞中达高峰。

The expression plasmid pGEX-5X-1/DFF45 was constructed and transformed into E.coli BL21, and the expression of GST-DFF45 protein was induced by IPTG. After purification, the fusion protein GST-DFF45 was used to immunize Oryctolagus cuniculus to obtain the antibody serum.

If sing on stage to just unilaterally pursue the daintiness of phonation while sing, but neglect "word" of clear, will make the audience listen to not pure phrase righteousness, hinder the contents expression of song. Where as, if sing on stage while sing just persistently pursue enunciation and vomit a word, but dissimilarity notice give out sound of beautiful, flowing freely, equally will die down art atmosphere and expression for sing.

如果演唱者在歌唱时只是片面的追求发声的优美，而忽略"字"的清晰，就会使听众听不清词义，妨碍歌曲的内容表达；反之，如果演唱者在歌唱时只是一味的追求咬字、吐字，而不同时注意发声的优美、流畅，同样会减弱歌唱的艺术感染力和表达。

The aim of this study was an evaluation of the influence of HiLoon aerobic performance and its physical effects. Elite swimmers、 collegestudents major in physical education and rats were exposed to simulatedaltitude in a decompression chamber and the followings were investigated:(1) erythropoiesis and erythropoietin,(2)maximal oxygen uptake,(3)body weight and body composition,(4)serum parameters of metabolism andhormone,(5)erythropoietin gene expression in kidney and vascularendothelium growth factor gene expression in heart.1 Effects of simulated "living high-training low" on aerobic performancein elite swimmersFourteen swimmers (10 men, 4 women) from Shandong swimming team weredivided into two groups: experimental group (living high-training low,n=8,6men,2women),living at a simulated altitude of 2,800m for 13 to 14 hours per day for 3weeks in a decompression chamber and training at sea level; control group(living low-training low, n=6,4 men,2 women),living and training at sea level.
