AIM: The incidence of malrotation after femoral shaft fracture treated with close reduction and interlocking intramedullary nailing is high. To judge the degree of rotational deformity in fracture of shaft of femur by C-arm X-ray machine is necessary in the repair of tissue construction.

目的：采用闭合复位带锁髓内针置入固定治疗股骨干骨折，术中常出现远端旋转畸形，利用C形臂X射线机并以健侧NH角（股骨头－颈轴线与水平台面的夹角）作为参照物，判断骨折端旋转移位程度是组织构建修复过程中必须解决的应用技术。

This malunion produced a cosmetic defor- mity only, without impairment of function.

其中4例患者，骨折近端只有一根克氏针贯穿；1例患者两根克氏针中的一根未贯穿双皮质；3例患者骨折端克氏针间隔不够，导致结果为单针固定。

All rats were sacrificed at 12 weeks after operation. the macro-pathological changes of samples were graded by mankin's scale.bone mineral density of right distal femoras and femora condyles were measured by dual-energy x-ray absorptiometry scanner.

术后12周处死动物取材，采用mankin评分系统评分；用双能骨密度仪测量右侧股骨远端1/4骨密度和股骨内外侧髁软骨下骨的骨密度；右侧股骨髁脱钙后切片，行番红&o&染色和mmp-13免疫组化染色；右侧胫骨近端做硬组织切片，测量软骨下松质骨的骨组织形态计量学参数。

一根纵向步道终止于人孔溢流盒前端，一根横向步道靠近后端框，一根横向短步道安装于靠近人孔溢流盒后端。

There found 4, 32 and 19 patients with lymph node metastasis inside mesorectum respectively at distal, lateral and proximal parts of the cancer, which was correlated with differentiation degree of the cancer. Circumferential resection margin involvement was found in the specimens of 9 patients and micrometastasis in those of the other 2 patients.

肿瘤远端、肿瘤旁和肿瘤近端直肠系膜内淋巴结转移的检出例数分别为4、32和19例，与肿瘤分化程度相关。9例标本存在环周切缘癌浸润(circumferential resection margin involvement，CRMI)，2例见微转移。

Site was detected near the centromere of metacentric chromosome, while the other homologous one had no hybridization signal.

在石蒜染色体上发现9个杂交位点，在1号长臂端部、5号近端部区域和6号长臂近着丝粒区域各有3个位点。

Thirty six homologous pairs of chromosomes were autosomes , in which chromosomes ,pairs of 1 to 20 were acrocentric-subterminal , 21 to 36 metacentric-submetacentric . And X chromosome was metacentric, Y chromosome terminal.

其中，1～20对常染色体为亚端着丝粒染色体，21～36对常染色体为亚中着丝粒染色体和中着丝粒染色体，X为中着丝粒染色体，Y为端着丝粒染色体。

All 29 pairs of autosomes were acrocentric chromosomes;X chromosome was the second largest acrocentric chromosome and Y was the smallest and the only one metacentric chromosome in all chromosomes.

所有常染色体均为端部着丝点染色体；X染色体为第二大的端部着丝点染色体，Y染色体为最小的且是唯一的中部着丝点染色体。

Objective : To analyze the clinical effects of treatment on distal metaphyseal Fractures with AO expert tibil Nail .Methods : From Feb. 2007 to Jan.

目的 总结运用专家型胫骨髓内钉治疗胫骨远端干骺端骨折的临床效果。

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。
