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.

The 10 a plot had the highest community average height, abundance, and above ground biomass, but the community average increased with enclosure time and the 25 a plot had the highest community average coverage. Enclosure for 10 a gave the highest species diversity index in the third plots, while 15 a had the highest' richness index and lowest evenness index. The highest evenness index was in the non-enclosure plot. Exclosure appears to maintain or conserve, rather than increase plant diversity in contrast to non-enclosure.

No entire nitrendipine crystals were observed visually in SEM photos. The results of X-ray diffraction and differential scanning calorimetry analysis indicated that the crystalline form of nitrendipine was highly dispersed in microspheres, so as amorphous state. The drug release rate of microspheres could be controlled with adjusting the ratio of solid dispersion carriers and retarding agents formulated. The agitation speed and temperature of the preparation process have distinct effect on micromeritic properties of microspheres. The release profiles of the microspheres were mainly affected by the stirring rate of paddle, the concentration of SDS and pH of dissolution medium. Cooling speed and time, however, have no evident influence on the drug release rate of the microspheres. The dissolution data showed that the mechanism of drug release from microsphers was mainly diffusion-controlled. The incorporation efficiencies of 3 batches sample were exceed 96. 8％, which implied that the current method was suitable for design sustained-release dosage form for poorly water-soluble drug.

The mate choice of Brandt′s voles Microtus brandti was investigated in the laboratory to study the mating system of this species. It was found that the female voles spent significantly more time visiting the partners than the strange males, but the male voles did not show any preference of the partners to the strange females. A female vole showed no difference in the copulatory behavior between an unfamiliar male and a familiar male which had copulated with her for 15 minutes, but she visited and fought the unfamiliar male significantly more than the familiar male. A male vole significantly preferred visiting and mating with an unfamiliar oestrous female to a familiar female which had copulated with him for 15 minutes.

The land use pattern had changed by a relatively large margin in Neijiang city from 1997 to 2005. The main tendency of this change is that with remarkable reduction of cultivated land that decreased by 9936.11hm~2, unutilized land and water area, while garden land, forest land that increased by 7032.23 hm~2, grass land and building land increased notably. And during the research time, the speed of land use type change reduced from garden land, traffic land, forest land, residential areas and industrial and minings land, cultivated land, unutilized land to water area. The main trend of general dynamic degree changed from progressive increase to degression. From the analyses of land use diversion matrix, we know resulting in the quantity change of land use was that cultivated land being occupied by construction,adjustment in structure of agriculture and the implementation of the national reforesting formerly cultivated land policy in Neijiang city.
