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.

The 54 accessions were classified into five major groups:Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ by cluster analysis using UPGMA, which showed significant relationship with the origin regions of accessions. Genetic differentiation between and within eight eco-geographical groups of C.dactylon was estimated by Shannon's diversity index, which showed that 63.81% genetic variance existed within group, and 36.19 % genetic variance was among groups, indicating rather large genetic distances among those germplasm, and there was a correlation between genetic differentiation and eco-geographical habits among the groups.

聚类分析结果表明，52份材料可聚为5类；基于Shannon多样性指数估算了8个狗牙根生态地理类群内和类群间的遗传分化，类群内的遗传变异占总变异的63.81%，类群间的遗传变异占总变异的36.19%，表明这些抗源材料遗传差异较大，各生态地理类群间的遗传分化与其所处的生态地理环境具有一定的相关性。

We review the effect of rare earth ions on bone metabolism as the following three aspects:(1) effect of rare earth ions on differentiation and function expression of osteoblasts and osteoclasts;(2) effect of rare earth ions on the osteogenic and adipogenic differentiation of bone marrow stromal cells;(3) effect of rare earth ions on bone mineral phase of animals.

objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查，对5种亚型的良性脑膜瘤的mr灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高，恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p＜0.05)，良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p＜0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p＞0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助，而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。
