To explore the possibility that the androgen may facilitate differentiation of hair follicle stem cells into sebocytes, we carried out experiments to test this hypothesis. The concrete steps to carry out this research were as follow: Firstly, observed the expression of AR and examined the expression of AR mRNA of rat vibrissa follicle stem cells in vivo in three defined phases of a hair follicle cycle, including anagen, catagen and telogen. Secondly, cultured HFSC deprived from vibrissa follicle bulge region in culture flasks and observed the expression of AR, ketertin 15 (K15), cluster of differentiation 34 (CD34) andβ1-integrin of those cells.

To test the hypothesis, neontal rat cadiomyocytes Treat with heat shock(HS,42℃,2h) to induce the expression of HSP70,then teated with 0.5mmol/L H2O2. We first found H2O2 can reduced cadiomyocytes apoptosis and HSP70 only over-expression in the HS group, other two group only express HSP70 a little in the test of expression of HSP70.Then we tested the concentration of Ca2+, the [Ca2+ ] of CON was 192.224+6.654, the [Ca2+ ] of H2O2 group was 290.6918+8.922and the [Ca2+]of HS group was 214.2633+4.484.To further determine how HSP70 repaired the Ca2+ homestasis, we measured calcium transient of each group.

实验中应用MTT和流式细胞技术检测细胞的凋亡，发现损伤组的存活率明显低于其他2组，热休克组(Heat shock group，HS group)细胞存活率略低于正常组细胞；免疫组化结果表明只有在HS组才检测到阳性反应，即是HSP70的表达，其他2组均为弱阳性结果；应用离子成像技术对细胞内钙离子浓度进行测定，发现损伤组290.6918+8.922明显高于正常组192.224+6.654和HS组214.2633+4.484，HS组细胞内的钙离子浓度略高于正常组；为了进一步探讨HSP70对于ROS引起的心肌凋亡过程中钙离子的调控机制，又对各组的心肌细胞进行了钙瞬变的测定。

To test the hypothesis that concentration polarization of atherogenic lipids may occur in the arterial system and play an important role in localization of atherosclerosis, we simulated and measured in vitro the luminal surface concentration of low density lipoprotein in local stenosis at the distal end of carotid artery by number simulation and laser scanning confocal microscopy, then we designed carotid stenosis model to test the role of LDL concentration polarization in atherogenesis.
