The femoral circumflex arteriography of the normal leg was done in 8 patients, and three of them were simultaneously done in a postion of internal rotating of straight leg. Results Comparison with the arteriographic findings in absence of traction, all retinacular arteries but inferior arteries were depicted few branches and less femoral head perfusion in all 9 patients, especially in that of medial femoral circumflex arteriography, as hip joint was tractating in neutral position with the same speed and volume of injecting contrast medium and, the veins were demonstrated poorly or delayed.

结果同一血管部位，同等对比剂注射流率、总量造影，与中立位无牵引状态下造影所见比较，9例患髋中立位牵引时，除外下支持带动脉，所有未损伤的支持带动脉均有不同程度闭塞，相应股骨头颈部灌注不佳或几乎无灌注，静脉显影延迟或显示不清，4例牵引力由3kg增至5kg时，上述改变更为明显；5例患髋维持伸直内旋位时，所有支持带动脉尤其细小分支未见明确显示，股骨头灌注差或未见明确灌注，改变甚于牵引时；2例正常髋内旋位时造影改变类似。

ABSTRACT Direct intrahepatic portacaval shunt is created between the retrohepatic IVC and portal vein intrahepatically, with partial portal flow shunted directly to the IVC. DIPS can eliminate the defect that the outflow vein—hepatic vein is vulnerable to stenosis or occlusion after TIPS.

直接性门腔分流是在肝后段下腔静脉与门脉之间建立肝内分流，将部分门脉血液直接分流入粗大的下腔静脉，解决了TIPS术后分流道引流静脉——肝静脉易狭窄或闭塞的缺陷。

Results MRI findings of nasopharyngeal carcinoma appeared as diffusely or locally thickened nasopharyngeal walls,and pharyngeal recess was closed and pharyngeal opening of auditory tube became shallow or disappeared,sometimes with parapharyngeal space、retropharyngeal space and logus capitis oppressed or invaded.

结果：鼻咽癌的MRI表现为鼻咽壁局限性或弥漫性增厚，咽隐窝闭塞，咽鼓管咽口变浅或消失，可伴有咽旁间隙、咽后间隙、头长肌受压或浸润及颈部淋巴结的转移，可见乳突积液，颅底骨质破坏。

Neuroimaging tests might improve selection of patients who could be treated with reperfusion therapies by identifying those with regions of salvageable brain tissue, a low risk for hemorrhagic transformation, or occlusions of large arteries that might or might not be amenable to therapy.

神经影像学检查可以识别可挽救的脑组织、出血转化风险较低的区域、可治疗或不可治疗的大动脉闭塞，藉此指导我们选择合适的患者进行再灌注治疗。

Objective:To sum up the clinical experience of subclavian artery serious stegnosis or occlusion treated with the stent implantation from humerus artery.

目的：探讨经肱动脉路径行锁骨下动脉支架植入治疗重度锁骨下动脉狭窄和闭塞的疗效。

Methods:The clinical results in treating subclarian artery serious stegnosis or occlusion with stent implantation from humerus artery were analyzed in 10 cases.

分析2005年9月至2008年3月采取经肱动脉逆行植入支架治疗锁骨下动脉重度狭窄和闭塞10例。术前诊断包括彩色多普勒超声检查和动脉造影确诊。

Results Classifying according to configuration as below widespread type (n=16), Tubercular type (n=4), nipple type (n=2). Hilar madd, dilatation of intrahepatic ducts and discontinuity of hilar biliary ducts occurred in all cases. The imaging of MRCP displayed obstmction, stenosis, and filling defects. Portal vein was invaded in 3 cases and presented as infiltration, stegnosis or occlusion of the vein.

The expressions of VEGF mRNA in renal cortex in B and group C increased greatly compared with A group at 8th week(P.01), And the expression was decreased more in C group than that in B group at the 8th week;④The light microscopes results showed that no pathological changes in group A; pathological changes were much obvious in group B:glomerular capillary lumen tumbling,lumens blocked,mesangial region widened,basal lamina thicking,mesenterium base inceased,the volume of glomerulus become large,cell population increased,renal tubule vacuolization, renal interstitium was infiltrated by lots of lymphocyte and mononuclear macrophage; pathological changes in group C was light,only see glomerular capillary lumen lightly stegnosis,few lymphocyte infiltrating.

免疫组化结果显示第8周B组大鼠肾皮质VEGF蛋白含量较A组显著增加(P.01)，C组VEGF含量较B组有明显减少(P.01)，C组较A组表达量仍然增加(P.01)；③第8周B组肾皮质VEGF mRNA表达较A组有明显上调(P.01)，与B组相比，辛伐他汀可以明显减少C组肾皮质VEGF mRNA表达；④光学显微镜下A组肾小球毛细血管腔均匀一致，无狭窄，肾小管-间质无炎症细胞浸润。B组则病变较明显：大鼠肾小球毛细血管袢塌陷，管腔闭塞，系膜区增宽，基膜增厚和系膜基质增多，肾小球体积增大，出现玻璃样变；肾小管尤其是近区小管肿胀、变性、空泡形成，肾间质可见大量淋巴细胞和单核巨噬细胞浸润。C组病变较轻，可见肾小球毛细血管管腔轻度狭窄，肾小管-间质见少量淋巴细胞浸润。
