Literature Research The etiological factors of POF are not still clear. The changes of sites and numbers in X chromatosome, X; autosome translocations, a forkhead transcription factor gene (FOXL2) mutations, FRAXA premutations and inhibits gene mutations are found in POF patients, so genetic disorders have been thought to be involved. Irradiation, chemotherapy or pelvic operations can damage ovaries and cause ovarian atrophy and failure, so it is thought one factor of POF.

一、文献研究 POF的确切病因目前尚不清楚，从POF患者体内检测到X染色体上位点和数目的变化，X染色体与常染色体间的平衡易位，脆性X基因前突变，FOXL2基因突变，抑制素基因突变等，故认为POF发生与遗传因素有关；由于放射、化疗或盆腔手术等可损伤卵巢，导致卵巢萎缩，出现卵巢衰竭，故也是导致POF的因素之一。

Bipolar hemiarthroplasty for intertrochanteric fracture is indicated for patients of more than 80 year old, thus the organic or systemic malfunctions should be corrected during perioperative period. Meanwhile, retaining of lesser trochanter and reconstruction of calcar femorale are of vital importance for improving periprosthetic biomechanics and reducing local complications.

人工股骨双动头置换术治疗股骨转子间骨折适用于80岁以上病人，因此在围手术期应尽可能纠正全身各器官及系统功能异常，同时，保留小粗隆并重建股骨距对改善假体周围生物力学及减少局部并发症具有重要意义。

Results The concordance between the location of MEG spike foci and the location identified by the ictal and interictal EEGs was 76.6% and 80.9% respectively, and the concordance with ECoG was 80.0%. In 39 operated patients, Engel Ⅰ was achieved in 21,Ⅱ in 10, and Ⅲ in 8. In the operated patients, intraoperative proper management was performed according to MEG-showed eloquent foci in 29 whose area to be excised involved the eloquent cortex, without postoperative exacerbation of neurosurgical dysfunction.

结果 MEG显示痫灶位置与发作间期和发作期V-EEG结果吻合率分别达76.6%和80.9%，与发作间期和发作期ECoG的吻合率均为80.0%。39例手术病人中，术后Engel Ⅰ级21例，Ⅱ级10例，Ⅲ级8例；其中29例拟切除的区域涉及到解剖学意义上的功能区，术中根据MEG显示的功能区位置进行了适当的处理，术后神经系统功能障碍未加重。

Methods Twenty eight pure New Zealand rabbits were used, of which four were for nerve localization and the rest were randomized into untreatment group and ultrashort wave groups, after the establishment of the nerve root compression models by inserting a silastic tube into the intervertebral canal to compress the sixth and seventh left lumbar nerve roots.
