结果 整个视野内骨陷窝空虚，无骨细胞存在，骨板尚清晰，部分骨板出现颗粒状嗜碱性染色，骨髓腔内，基本无细胞结构，血管闭塞，哈佛氏系统结构不清，部分区域骨板层状结构消失，呈一片均质的嗜伊红染色。

At 4 weeks following implantation, cells on the surface of coralline hydroxyapatite were found and connective tissues were seen in the material pores in the experimental group. Cells on the coralline hydroxyapatite were observed only in the control group. At 8 weeks, new bone formation was detected on the surface of coralline hydroxyapatite; bony tissue deposition and a few chondroid tissues were found in the pores or surrounding the pores in the experimental group. A few fibrous connective tissues were observed in the control group. At 12 weeks, abundant mature woven bone was detected on the surface of coralline hydroxyapatite; medullary cavity-like structure and vessels were found in some regions in the experimental group. No new bone or bony tissues were found in the control group.

植入材料后4周，实验组可见珊瑚羟基磷灰石表面有细胞生长，孔隙内有结缔组织长入；对照组仅见珊瑚羟基磷灰石表面有细胞生长。8周时珊瑚羟基磷灰石表面有新生骨形成，孔隙内和孔隙边缘可见骨样组织沉积和少量软骨样组织形成；对照组仅见少量纤维结缔组织长入。12周时珊瑚羟基磷灰石材料表面有较多成熟编织骨形成，部分区域可见髓腔样结构形成，并有血管长入；对照组仍未见新骨及骨样组织形成。

Results CT displayed the lesions located in the bladder neck and triangle area in 7 cases, in the right anterior wall in 1 cases, involve the entire bladder wall in 2 cases. Eight cases showed the local thickening or nodular or flat dune-like shape thickening of the bladder wall, the size of the lesions were 1.0cm × 0.8cm ~ 4.3cm × 5.9cm, two cases showed the diffuse thickening of the bladder wall. Cystal low density were demonstrated in 2 lesions.The bladder exine were smooth in 9 cases.

结果 10例CG中CT表现为膀胱颈部和三角区7例，右前壁1例，累及整个膀胱壁2例。8例CT平扫表现为膀胱壁局限性增厚或呈结节状、扁丘状突向膀胱腔内的软组织密度影，大小1.0cm×0.8cm～4.3cm×5.9cm，2例膀胱壁弥漫性增厚，边缘光整。2例病灶内可见囊性低密度区。9例膀胱外壁光滑。

On cystoscopic examination, an external compression mass covered with normal bladder mucosa could be seen at the right lateral wall.

核磁共振扫瞄发现在膀胱的右侧有一管腔内的圆形肿瘤，疑似壁内的神经的或间叶的肿瘤。

This graft interferes with endosteal circulation and consequently can interfere with healing.

髓腔内植骨会干扰内骨膜血液循环，因此会干扰骨折的愈合。

Lactide, glycolide or caprolactone, biodegradable polyester and diisocyanate as materials are first bulk melt polymerized to prepare the degradable polymer with thermal deformation transforming temperature of about 37 deg.c. The obtained material is processed at temperature over melting temperature so as to shape into spiral rack, applied with stress at temperature higher than Ttrans to form shape easily operational handling and frozen to eliminate stress into the product.

本发明以丙交酯、乙交酯或己内酯，生物可降解聚酯及二异氰酸酯为原料，通过本体熔融聚合制备得到热致形变温度转化点在37℃左右的可降解高分子材料，将得到的材料在熔融温度以上进行加工、赋形制作成用于不同管腔内的螺旋管状支架；在T＞T trans 条件下施加应力，加工为便于手术操作的形状；冷冻定型消除应力，即得产品。

expandable intramedullary nail system has the unique technique principle, which has "hourglass" effect of homogenic load distribution and the advantage of no need of reaming and interlocking as well as the high power of anti-rotation resulting from the head of the peg in the femoral head. The fixation of Fixion PF for peritrochanteric fractures in old patients is mini-invasive .

Fixion PF可膨胀髓内钉固定原理为沙漏样固定，应力均匀分布于股骨髓腔，股骨头栓钉于股骨头内膨胀，增加抗旋转能力，不需扩髓、远端交锁，其独特的设计原理可减少创伤和相关手术并发症，尤其适合于老年骨质疏松性股骨近端骨折的治疗。

Results The bronchi stricture can be seen at lobar bronchus or segmental bronchus and the bronchial walls were thickened. No mass and opposite "S" sign can be found in all the cases. Among them,centripetal stricture can be found in 6 cases, and eccentric stricture in 11 cases. Bronchi stricture with obstructive atelectasis in 12 cases. In which "Air bronchogram" can be found in 9 cases. Bronchi stricture with pleural effusion in 8 cases. With intrabronchial polypoid shadows in 5 cases. With active pulmonary TB in 9 cases.

结果：17例均有肺叶或肺段支气管起始部和/或分支部不同程度狭窄及管壁增厚，无肿块及反S征；其中，向心狭窄6例，偏心狭窄11例；狭窄伴肺叶或肺段不张12例，其中不张或实变区可见充气支气管征9例，占75%；伴胸腔积液8例；伴管腔内息肉样软组织影5例；伴肺内结核9例。

Then the muscle pack was placed intradural, and the gelfoam soaked with ZT mucilage was tamponed intra-and extra-dural to support the packing.

结果显微镜下凿开鞍底充分暴露硬膜漏口，向硬膜漏口内填塞肌肉块，无脑脊液流出后，用渍ZT胶的明胶海绵填塞于硬膜漏口的内、外侧和蝶窦腔。

Increases in Penh alues after methacholine challenge were also correlated with increased intrapleural pressure, measured ia an esophageal tube.

乙酰胆碱激发后Penh的增高也与胸膜腔内压的增高相关联，这可通过食管内导管测定。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
