Three antioxidative parameters(SOD super oxide dismutase、MDA malondialdehyde and GSH reduced glutathione hormone)were also measured.Results:The skin elasticity and water content improved increasingly according to the MPA measurements of the two group 4 weeks after the last irradiation.The hydroxyproline of the skin in the Q-switched 1064-nm Nd:YAG laser of 0.6J/cm~2、1.5 J/cm~2 and 2.5 J/cm~2 group showed 7.1%,13.1%and 19.8%(p＜0.05)increase respectively compared to their controls,the enhancement of dermal thickness were 15.5%,29.7%and 38.4%;The hydroxyproline of the skin in the Q-switched 532-nm Nd:YAG laser of 0.5J/cm~2、1.2 J/cm~2 and 2.0 J/cm~2 group showed 6.9%,9.6%and 14.2%(p＜0.05)increase respectively compared to their controls,the enhancement of dermal thickness were 5.5%,15.1%and 29.9%,among which the Q-switched 1064-nm laser group had the greatest effect. The result of antioxidative parameters showed some juvenescence change at the radiated skin.

The plasmid of pEGFP-N1 was preserved in our laboratory.②The rat vibrissa follicles were dissected under a stereomicroscope. The dermal sheath was moved by incubated in dispase. The bulge regions of the hair follicles in anagen phase were carefully cut between the arrector pili muscle and the sebaceous gland, and then incubated with a mixture of trypsin and EDTA. The cell suspension was selected, and cultured in 10% fetal bovine serum DMEM/F12 FAD medium. After 7 days culture, HFSC was obtained by rapid adhering on collagen Ⅳ.
