骨发生

Anatomical studies of femoral endosteal geometry suggest that exact fit of a prosthesis within the cortex is implausible because of large ariations in anatomy and age-related changes in the diameter of the canal.

对股骨髓腔几何形状的解剖学研究表明，由于髓腔的解剖变异相当大并且其直径随年龄而发生改变，故要达到假体与骨皮质完全密贴是不太可能的。

Male, 25 years old, teacher, has epigastric pain usually before meals for two years.

男性，25岁教员，常于饭前上腹痛，已两年之久。关节痛和骨痛可能会发生。

Current research focused mostly on the development and restoration by regeneration of cartilage of limb joints and epiphyseal growth cartilage, but it is still incipient to study the development and the mechanism of physiological rebuilding and restoration by regeneration of condylar cartilage.

机体其它组织损伤是通过瘢痕而愈合，而骨和软骨则通过自身组织的再生来完成改建和损伤的修复，此功能主要是由于胚胎时期骨架的发生与出生后骨架生理性改建及损伤修复的分子机制相似的结果。

Correct diagnosis were made in 34 malignancies and 6 false positive lesions were excluded based on moiphology and 18F-FDG uptake status of the lesion. There were 6 false positive and 2 false negative cases. Furthermore, extrathoracic metastases which were not showed on previous CT image in 4 patients including one in the adrenal gland and 3 in the bone were detected by 18F-FDG imaging.

根据形态及核素摄取特征，18F-FDG符合线路显像正确检出恶性病变34例，排除恶性病变6例，出现假阳性6例和假阴性2例，对原发肺癌诊断的灵敏度、特异性和准确性分别为94.4％、50.0％和83.3％；同时，在4例患者中检出了CT未发现的、发生于肾上腺和骨的肺外转移。

During the procedure of distraction, geniohyoid expressed hypertrophy and hyperplasia initially and then restore normal level after distraction, while masseters was influenced rarely.

结果发现在牵张过程中，颏舌骨肌先是发生再生与肥大，最终组织学形态恢复至牵张前的形态；而嚼肌受其影响不大，只是在牵张5天时有轻度的萎缩，可能与牵张过程中引起的干扰有关。

The fusion rate of allograft+rhBMP-2 in lumbar posterolateral intertransverse fusion exeperiment in rabbits was 100%, and superior to autologous iliac crest and sustitute it.

得出结论：同种冷冻干燥异体骨+rhBMP-2复合物在兔子腰椎后外侧融合实验中，优于自体髂骨，可以取代自体髂骨，其融合率为100％，消除了假关节的发生。

Objective: The experiment will to observe: 1、the compound composed of carriers and rhBMP-2 excels or is similar to autologous iliac crest in posterolateral intertransverse spine arthrodesis in rabbits, 2、it may eliminated thd nonuions, 3、To explore the biologic process in spine arthrodesis and the role that accelaterated spine arthrodesis, 4、the roles of HA in spine fusion, by those compounds are used in posterolateral intertransverse fusion in rabbits.

目的：本实验通过rhBMP-2、HA复合物在兔子腰椎后外侧横突间融合的过程，观察了解：（1）rhBMP-2复合物在兔子腰椎后外侧横突间融合中，其作用能否优于或至少与自体髂骨相同，能否取代自体髂骨，免去取骨术。（2） rhBMP-2复合物的应用能否消除不融合的发生。（3）进一步了解脊柱融合的生物学过程，及rhBMP-2在脊柱融合生物学过程中所起的作用。（4）探讨HA在脊柱融合中的作用。

Dec. 6, 2002 Many cases of pelvic pain may be related to interstitial cystitis, according to the results of a study using the intravesical potassium sensitivity test.

Dec。 6， 2002─根据一项利用PST方法检查所做的研究结果显示，许多骨盆腔疼痛的原因事实上很可能是因为间质性膀胱炎所引起的，而且间质性膀胱炎在美国发生的频率可能是过去所预测的20倍。

All tumors were histologically high grade (6 grade III and 10 grade IV). Three tumors showed heterologous elements, 2 osseous, and 1 rhabdomyoblastic. More often scattered than diffuse, S-100 protein staining was noted in 11 of 16 tumors and variable collagen IV staining in 10 of the 16. Immunoreactivity for p53 protein was diffuse and strong in 7 of 11 tumors. Twelve patients died within 17 months to 3 years of diagnosis, 1 was lost to follow-up, 2 are very recent cases, and 2 patients are currently alive, 1 after 2 recurrences, and another with spinal leptomeningeal metastases.

所有病例在组织学上都是高级别（6例III级和10例IV级）。3例肿瘤含有其他成分：2例含骨和1例含 rhabdomyoblastic.S-100蛋白染色显色于16例肿瘤中的11例，IV型胶原染色显色于16例中的10例，这些染色通常分散而不弥散。11例肿瘤中7例的p53蛋白免疫反应弥散且强烈。12例病人死于确诊后的17个月至3年，1例随访失败，2例是最近的病例，还有2例现在还活着，其中1例复发，另1例发生脊髓脑膜转移。

The abnormal condition of telomere is involved in chronic compartment syndrome in lumbosacral region.

端粒的异常状态参与腰骶部慢性骨筋膜间隔综合征的发生。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
