Results Intra-articular hemorrhage was observed in 1 patient and intra-osseous hemorrhage in 7 patients. The injury of retinacular arteries and reduction of blood supply were found in each case. In the presence of hip traction, blood flow of retinacular arteries reduced markedly. Few branches and little femoral head blood perfusion were observed in all of retinacular arteries, while hip joint was internally rotated with the sick leg straightened in the patients.

结果 12例中髋关节囊内出血1例，骨内出血7例， 12例均出现持带动脉损伤和血供减少；患髋牵引时支持带动脉供血减少；髋关节维持伸直内旋位时所有支持带动脉无明确显影或仅显示其主干。

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。

To compare the effect on operative exposureamong retrolabyrinthine approach,PLPA approach and translabyrinthine approach.Methods (1)Vessels perfusion and microanatomy were performed in 15 cadavericheads.Outlines of temporal bone and space relationship between inner structureswere measured.

Four aspects of research achievements include:(1)several imaging correction methods and strained estimation methods for biological tissues elasticity imaging were investigated as well as elasticity reconstruction and phantom, in vitro and in vivo elasticity imaging experiments;(2)in the fields of biological microsystem and perfusion evaluation for microvascular system, three kinds of microbubbles whose shell are albumin, sugar ester and surfactant respectively were designed and produced, then the methods to estimate the thickness of their shells were presented, moreover, the interacting mechanism of ultrasound contrast agents and tissues, as well as protein drug delivery under the condition of ultrasound sonification were studied in the molecular level;(3) At the aspect of high intensity focused ultrasound therapy system, we designed and constructed the 256-element HIFU transducers using 1-3 composite materials. And furthermore we developed the integrated HIFU system with 256-element HIFU transducers. And we made preliminary and important progresses in the research of HIFU bioeffect, lesion estimation, techniques of monitoring and imaging and characterizing of structure of HIFU transducer;(4)The real-time method of voice source regeneration based on compensative regulation of physiological parameters was investigated in the field of medical rehabilitation. We addressed the physiology and biophysics of vocalization, modeled voice source regeneration based on compensative regulation mechanism, and put forward an integrated evaluation about the speech rehabilitation and the regenerated voice source; Sixty-one archived journal papers were published, as well as ten in international journals, and eighteen publications were embodied by SCI.
