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.

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。

From differentiation of soybean varieties and photoperiod adjustment, anatomical differentiation essence of different types of stem termination soybean varieties, variation law of stem termination development under different photoperiod treatments, effect of long day on the terminal raceme of soybean, regulation rules of AGAMOUS gene among different soybean varieties and under different photoperiod treatments were studied, which would provide theory base of plant type breeding of soybean especially improvement of podding-habits and cultivation and management of soybean.

因此，试验于2006和2007年在中国农业科学院作物科学研究所完成，主要从大豆的品种差异和光周期调控入手，利用解剖学和分子生物学技术，研究不同结荚习性大豆品种的本质差异、大豆在不同光周期处理下茎顶的变化规律，进一步明确长日照对大豆顶端花序的影响，及AGAMOUS基因在不同光周期处理下大豆品种中的表达规律，为大豆株型育种特别是结荚习性的改良及大豆栽培管理提供理论依据。

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。

Besides, the genetic differentiation also existed among subpopulations. We deduced that the limited gene flow and breeding type were important factors leading to genetic differentiation. The genetic structure of Aristida pennata populations reflected its characteristics of clone reproduction and the good adaption to the severe environments.

本研究认为羽毛三芒草种群遗传多样性很丰富，遗传结构较为复杂，亚种群间遗传多样性大，亚种群间存在一定遗传分化，基因流和繁育方式是导致种群遗传分化的主要因素。

本研究结果表明，杨桃新梢上的芽在进行形态分化的过程中，枝条仍在积累碳水化合物。

From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .

体表皮由外及里共分为角质层、透明层、颗粒层、棘细胞层、基底层，EGF可以通过透明层、颗粒层、棘细胞层深入肌肤基底层，加速基底层细胞增殖分化，将已经分化成熟的细胞逆分化成干细胞，当达到一定量时，便会形成&干细胞岛&，加速新细胞的生成，让衰老细胞快速角化、脱落，已断裂、变性的胶原纤维和弹性纤维得到修复，皮肤弹性增加，皱纹逐渐平复、消失。
