Results The values of bone density in weight-bearing, superolateral non weight-bearing and inferomedial non weight-bearing areas after femoral neck fracture in patients with osteoarthritis were lower than normal.

在骨密度测量方面，多数作者采用双能X线吸收测定法(dualenergyX rayabsorptiometry ，DEXA)，所获得的结果是骨性关节炎患者骨密度是增高的，并认为，骨密度增高可以降低骨折发生率；另外一些研究则显示骨性关节炎患者骨折发生率与致伤因素及暴力大小有关，与患者骨密度无关[2 ] 。

Objective To study the pathogenesis and clinical symptoms of patient with central type of interˉvertebral disc protrusion manifested intermittent claudication as the mainly clinical presentation,so as to reach the early diagnosis and treamtmet in time.Methods In58cases,X-ray film,lumbar discography,CT examinations were done to confirm the diagnosis,then total laminectomig was performed to reveal the vertebal body without involving small arˉticular process.Intervertebral tissue was excised via duralotomy approach in2cases in remaining56cases,through right and left longitudinal syndesmotomy to resect the nucleus pulposus of lumber intervertebral disc.Results In58cases treated by operation,the operative findings were in according with the X-ray and CT examinations ofpre-opˉeration.

目的 对呈间歇性跛行主要临床表现的中央型椎间盘突出症患者的发病机制和临床表现进行研究，达到早诊断、早治疗方法对58例患者进行X线拍片，腰椎碘造影，CT扫描检查，根据检查结果确诊后，采用全椎板切除显露椎体，未累及小关节突，2例经硬膜切开入路切除间盘组织，余56例经从双侧用神经剥离子带棉片将硬脊膜带神经根向中线剥拉至显露圆形突出物止，分别从左右纵韧带摘除髓核。

And then, the pBI101.2 wirelike vector and the promoter fragment of 886bp were acquired. Becase the promoter was modified by the HindⅢand BamH I, the acquired target genes fragment, digested by the restriction endonuclease, was matched to the wirelike vector.

由于在启动子两端有人工设计合成的HindⅢ和BamHⅠ酶切位点，经上述双酶切消化后，回收目的基因片段与线状载体的粘性接头恰好匹配。
