Results: The tHey and blood fat level in blood plasma and expression of MCP-1mRNAof aorta on model group is obviously higher than that of control group (P＜0.05);the result of immunohistochemistry shows that the expression of VCAM-1 and MMP-2enhanced, Bcl-2 is lower; aorta slice shows endarterium discontinuation, strippingpartly, smooth muscle cell arrange puffly and chaotic, infiltration of lipoid ofdifferent degree are observed in aorta wall, pathological changes suffusion, morexanthoma cell, plaque protrude lumens. The they and blood fat level in blood plasmaand expression of MCP-lmRNA, VCAM-1, MMP-2 of aorta on intervention group aremuch lower than that of model group (P＜0.05); Bcl-2 of intervention group isstrengthened, and the pathomorphology and immunohistochemistry of aorta showpathological changes are slighter than model group.

结果：模型组，血浆中同型半胱氨酸浓度、血脂水平、主动脉MCP-1mRNA表达显著高于正常对照组(P＜0.05)，免疫组化示主动脉内皮细胞VCAM-1、MMP-2表达增强，Bcl-2表达降低；主动脉切片发现动脉内膜不连续，部分剥脱，平滑肌细胞排列疏松、紊乱，主动脉壁均见到程度不同的脂质浸润，其病变弥漫，泡沫细胞较多，可见斑块突出管腔；干预组，血浆中同型半胱氨酸含量、血脂水平显著低于对照组和模型组(P＜0.05)，主动脉MCP-1mRNA、VCAM-1、MMP-2表达显著弱于对照组和模型组(P＜0.05)，Bcl-2表达增强(P＜0.05)，主动脉病理形态学和免疫组织化学检测示病变轻于模型组。

The tumor is lobulated under microscope, some immature Sertoli cells were arranged as either amorphous plaques, funicular, broad beam, nest, solid or hollow tubules; Leydig cells existed individually or in clusters, and their cytoplasm was abundant and eosinophilic.

镜下肿瘤呈分叶状，有不成熟的支持细胞排列呈片块状、不规则形或条索状、宽梁状、巢状、实性或空心的小管；莱迪细胞呈单个或簇集存在，细胞浆丰富且嗜酸。

Methods Cultured in vitro pulmonary artery endothelial cells were treated with large , middle and small doses of DHAP, and a control group was set up. The deformation process was observed using micropipette aspiration technique.

体外培养肺动脉内皮细胞，分对照组及青心酮大，中，小剂量处理内皮细胞，用微管吸吮技术观察细胞的变形过程。

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

结果 采用神经管植块法培养的神经嵴干细胞，免疫细胞化学染色呈现nestin及P75双阳性，将其接种在壳聚糖纤维支架材料上，可见神经嵴干细胞贴附于壳聚糖纤维上生长；S-100免疫细胞化学染色显示，S-100阳性细胞突起的末端呈扁平状膨大；扫描电镜显示，壳聚糖纤维上的躯干神经嵴干细胞为梭形，呈现"端对端"、"肩并肩"排列，伸出爪形伪足贴附于壳聚糖纤维上。

Bax protein was expressed mainly in spermatogoni and primary spermatocytes, and sometimes the expression was also seen in spermatids and spermatozoa within some seminiferous tubules.

Bax蛋白主要表达于精原细胞和初级精母细胞，部分曲细精管中的精子细胞和精子也有表达。

A Sertoli cell resides in testicular seminiferous tubule, which is the only body cell contact with the spermatogenic cell, plays a crucial role of regulation in the process of spermatogenesis.

Sertoli细胞位于睾丸生精小管内皮，作为与生精细胞接触的惟一体细胞，在生精过程中起至关重要的调控作用。

Immunohistochemistry for HIF-1α: HIF-1αexpression was detected in germ cell cytoplasm cytoplasm, obviously spermatocyte,and was detected in nucleus of seminiferous tubule theca cell too.

免疫组化观察HIF-1α的表达情况： HIF-1α表达主要见于生精细胞的细胞质，以精母细胞明显，也见于曲细精管外周膜细胞的胞核。
