Sex of arteriosclerosis of result lower limbs is out-of-the-way 2 dimension behave disease on supersonic image for pathological changes blood-vessel inside in film is shown irregular add thick, local show strong echo spot, and to hemal antrum inside protuberant, hemal antrum internal diameter shows irregular stricture, pathological changes paragraph solid sex is low it is thus clear that inside hemal antrum echo smooth group fills up; color much general straps blood stream to show resemble showing to; of blood stream signal is not had inside hemal antrum multilayer helix CTA shows pathological change paragraph hemal area does not have comparative agent, show what side raises artery to take travel and initiative place at the same time.

结果下肢动脉硬化性闭塞症二维超声图像上表现为病变血管内中膜呈不规则增厚，局部呈强回声斑，并向血管腔内突起，血管腔内径呈不规则狭窄，病变段血管腔内可见实性低回声光团充填；彩色多普勒血流显像显示血管腔内无血流信号；多层螺旋CTA显示病变段血管区域无对比剂，同时显示侧支动脉的走行及起始部位。

The superficial microvascular networks were sparser, while the subpleural microvascular networks were denser. The superficial blood vessels and the interlobular blood vessels were mutual transitional, and the anastomosing between the superficial blood vessels with the subpleural vessels. According to the branching sequence of the subpleural arteriole, it could be divided into the arteriole, terminal arteriole, precapillary arteriole and capillary in turn. The subpleural capillary networks were mainly web-like, while small holes were also found on the cast. The honeycomb vascular networks were various in size and form at a low magnification. The outline of alveolus, alveolar sac, alveolar duct and respiratory bronchiole and terminal bronchiole, made of microvascular networks, could be found in the cut surface.

胸膜面浅层的微血管网稀疏，深层的胸膜下微血管网致密；胸膜面浅层的微血管与小叶间隔的微血管之间相互移行，与胸膜下微血管之间形成吻合连接；根据胸膜下微动脉连续分支的顺序，常可将其分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管四级；胸膜下毛细血管网主要以网络状的形式存在，但在铸型上均可见数量不等的"小孔状"结构；低倍镜下肺实质内微血管网呈现大小不等、形态各异的蜂窝状结构，可以见到由微血管网构成了肺泡、肺泡囊、肺泡管和呼吸性细支气管以及终末细支气管等结构的轮廓。

The vessels from the lung parenchyma branched into the pleural superficial vessels, the interlobular vessels and the subpleural microvessels. The subpleural arterioles also could be divided into arteriole, terminal arteriole, precapillary arteriole and capillary in turn. Most subpleural capillary meshes were web-like, and also the small holes and sieve-like meshes occurred in the subpleural microvascular networks. The interlobular blood vessels and the superficial blood vessels were mutual transitional.

从肺实质内穿出的微血管可发出分支至胸膜面浅层、小叶间隔和胸膜下微血管网中；胸膜下微动脉也可分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管四级；胸膜下毛细血管网多数呈网络状，也可见到呈"小孔状"的结构和筛网状的血管网；小叶间隔的微血管与胸膜面浅层的微血管之间可以相互移行。

The pleural superficial blood vessels were smooth, while the circular and oblique constrictions of smooth muscle cells occurred on the surface of the subpleural arteriole, venule and parenchymal venule. The round imprints of endothelial nuclei were found on the cast surface of the arteriole and venule.

胸膜面浅层的微血管铸型表面光滑，胸膜下微动脉或微静脉以及肺实质内微静脉的表面可以见到呈环形或斜形的平滑肌细胞的压迹，微动脉和微静脉的表面可见圆形内皮细胞核的压痕。

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .

早期研究开始，许多学者即发现其与免疫学有密切关系，至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen，HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast，EVCT)上，即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层，与母血及子宫组织直接接触的滋养细胞，这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。

People often occur in elderly vascular sclerosis, high blood pressure sustained more easily lead to cerebral arteriosclerosis, vessel wall hyalinization appears fat, thus weakening the strength of the vessel wall, together with the blood of the structure of the wall is relatively weak, the middle vascular myocytes less, the lack of external elastic layer developed arterial adventitia easily occurred in the brain artery wall limitations small expansion, the formation of micro-miliary aneurysm.

人到老年血管常会发生硬化，持续的高血压更容易导致脑动脉硬化，血管壁出现脂肪玻璃样变，从而削弱血管壁的强度，加上脑血管壁的结构比较薄弱，血管中层肌细胞少，缺乏外弹力层，动脉外膜不发达，容易造成脑内小动脉壁发生局限性扩张，形成粟粒性微动脉瘤。

Results The artery frequency spectrum of high speed and low resistance were found in malignant trophoblastic tumors. The ulterine muscular layer in malignant trophoblastic tumor was hypervascular and the resistive index was less than 0.4. After chemotherapy, the hypervascularity decreased, RI increased higher, and β-HCG returned normal.

结果 恶性滋养细胞肿瘤子宫动脉RI值较低，为高速低阻力性动脉频谱；恶性滋养细胞肿瘤宫壁血流异常丰富，子宫肌层病灶内血管阻力指数RI.4；恶性滋养细胞肿瘤患者全身化疗取得疗效后子宫肌层血流丰富区逐渐缩小，RI呈逐渐升高趋势，血β-HCG逐渐恢复正常。

Was simultaneously injected into cisterna magna at the second injection blood in the presence of subarachnoid blood. At 2 to 4 days, GFP was expressed in leptomeninges over the brain stem, cortex and cerebral arteries, smooth muscle cells of small vessels were occasionlly transduced. GFP was expressed in adventitia of spastic basilar artery on days 2 (day 5 after first injection blood) after injection 〓, but was undetectable by days 4, transgene was not expressed in medial or intimal layers. The prensence of subarachnoid blood can not prevent access of adenovirus to vessels and transgene expression.

注入腺病毒载体后2天（初次注血第5天）行荧光显微镜、免疫组织化学和RT-PCR检测，结果在颅内大血管如基底动脉的外膜可见外源基因的表达，而外源基因不能转移至血管中膜和内膜，4天时（初次注血第7天）基底动脉的外膜中外源基因表达消失；注入腺病毒载体后2～4天，外源基因可以有效转移至颅底软脑膜细胞，小血管外膜和平滑肌层也可见外源基因的表达，表明蛛网膜下腔内的血凝块不能阻止腺病毒载体介导外源基因转移至颅内血管。

There were two layers of tissue in the pterygopalatine fossa,they are posteromedial nerve layer and anterolateral vessel layer.The distance from the internal carotid artery to the sphenopalatine foramen was 16.4±3.3 mm.

结果：蝶腭孔、圆孔、翼腭裂距离前鼻嵴的距离分别为(62.3±2.7)、(64.2±4.8)、(51.5±0.6) mm，翼腭窝内的结构可以分为在后内的神经层和在前外的血管层，颈内动脉与蝶腭孔之间的距离为(16.4±3.3) mm。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
