Ankylosing spondylitis, a rheumatic inflammatory disease primarily affecting the spine and sacroiliac joints, is also called Morbus Bechterewin some European countries.

一种开始影响脊椎和骶髂关节的风湿性炎症疾病，在某些欧洲国家亦称为&别赫捷列夫关节病&。

They say removing gravity from the human body makes it act as though it is aging more quickly, increasing bone and muscle tissue wastage and making heart problems more frequent.

他们说，失重可使人体加速衰老，增加骨髂和肌肉的退化，还使心脏频频出现问题。

The procedure performed included 23 crossover saphenous vein bypasses 5 in situ saphenopopliteal bypasses 4 interventional therapies of iliac venous occlusion 2 muscular flap constructions on the popliteal vein 38 varicose vein strippings partly with the ligature of communicating venous and ulceration skingraftings 22 endovenous laser treatments of varicosis partly with ulceration skingraftings 17 simple ulceration skingraftings and 3 free flaps transfer for ulceration.

全组105例患者，共114条患肢，其中23条行大隐静脉交叉转流术， 5条行原位大隐静脉-腘静脉转流术， 4条行髂静脉介入治疗， 2条行腘静脉外肌袢形成术， 38条行曲张浅静脉剥脱术，部分联合交通静脉结扎和溃疡清创植皮术， 22条行曲张浅静脉腔内激光术，部分联合溃疡清创植皮术， 17条行单纯溃疡清创植皮术， 3条行溃疡清创联合游离皮瓣移植术。

起源于髂外动脉系的异常闭孔动脉，按侧别计，其出现率为20％；按尸体计，其出现率为33.13％。

Results: 1 The distances from L4, L5 spinal nerves and obturator nerve to sacroiliac joint were (20.24±1.12) mm,(23.80±1.43)mm and (16.26±2.07)mm respectively.

结果：(1)L4、L5及闭孔神经距离骶髂关节分别为(20.24±1.12)、(23.80±1.43)、(16.26±2.07)mm。

Methods:(1) The distances from L4, L5 spinal nerves and obturator nerve on the superior border of sacrum ala to sacroiliac joint were measured on 12 adult cadavers (24sides).

(1)采用12具（24侧）成人福尔马林固定尸体标本，测量骶骨翼上缘L4、L5及闭孔神经到骶髂关节距离。

Methods:A total of thirty axial pedicled groin flaps were applied clinically.

目的：为重新评价髂腹股沟部带蒂皮瓣的临床应用价值。

Methods 50 eases (56 hips) sere undergone THA. A K-wire was inserted perpendicularly into femur at subtrochanteric level, the femoral neck fracture was repositioned and the other sire was inserted into the iliac crest paralleled with the former wire in the identical vertical axis.

对50侧（56髋）行全髓置换术，在股骨转子下垂直打入第1枚克氏针，在该针纵轴线相对应的髂嵴上打入第2枚克氏针，测量两针之间的距离。

Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves. The sciatic trunk descended in front of the sacroiliac joint and escaped between the sacral bone and ilium, then left the pelvis from the greater sciatic notch. The segment of sciatic trunk which ran between the sacrum and ilium was stable and feasible for localization according to the related bony structures in CT scanning, so it was selected as irradiation target. After high dose of stereotactic radiation, the degeneration and necrosis in nerve fibers could be observed under microscope.

结果：通过解剖可见坐骨神经主干由第7腰神经和第1、2荐神经组成，坐骨神经主干从荐髂关节下、荐骨和髂骨之间穿出后，跨过坐骨大切迹的一段坐骨神经主干位置恒定，且有荐骨和髂骨做定位标志，可作为CT定位的照射靶点，单次大剂量照射后镜下可见神经纤维变性坏死。

A radiosurgery treatment planning was performed on the selected nerve segment, its changes of pathology and ultrastructure were observed. Results: Base on the dissection, the rabbits' sciatic nerve was composed of the seventh lumbar nerve and first and second sacral nerves. The sciatic trunk descended in front of the sacroiliac joint and escaped between the sacral bone and ilium, then left the pelvis from the greater sciatic notch.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
