表皮形成

DATA SYNTHESIS: With the increase of ultraviolet radiation caused by environmental pollution, DNA in human epidermal cells is damaged. Cyclobutane pyrimidine dimmer and 6-4 photoproducts are the main forms of DNA lesions.

资料综合：环境污染使得紫外辐射增强，而紫外线辐射对机体表皮细胞的DNA具有损害作用，可导致环丁烷嘧啶二聚体和6-4光产物的形成。

Ozone College depletion in stratosphere has led to the increase of solar UV-B radiation reaching to the earth surface, which would damage DNA of plant epidermal cells and produce cyclobutane pyrimidine dimmers (CPD and 6-4 photoproducts.

臭氧衰减导致地表紫外辐射增强，而紫外线辐射对植物表皮细胞的DNA具有损害作用，可导致环丁烷嘧啶二聚体和6，4-光产物的形成。

Result: The average healing time of superficial second degree burn wound was 7 days with epidermidalization; deep second degree burn wound achieved physiological healing in 22 days; while superficial third burn wound were healed in 35±days. The total cure rate was up to 98.92%, and scarring rate accounted for about 12%.

结果：浅Ⅱ度创面治愈时间，平均7d全部表皮化愈合，深Ⅱ度创面平均22d也生理性愈合，浅Ⅲ度创面在35d±5d愈合；总治愈率达98.92%，瘢痕形成率约占12%。

The proliferation and kinetics, cell cycle, clonalforming rate, and apoptosis of MEC- 1 cells, before and after FHIT gene transfection in vitro, and tumor loci formedon mice after injection of transferred MEC- 1 cells in vivo were observed by immunochemical staining, flow cytometryanalysis, and so on.

结果外源性FHIT基因转入黏液表皮样癌MEC- 1细胞后，S期细胞显著减少，G1期细胞增多；细胞倍增时间从（21.03±0.41）h延长为（26.86±0.71）h；软琼脂克隆形成率显著降低；细胞发生退行性改变和出现凋亡早期表现。
