Results: In the 23 cases of disease group, 16 cases were unilateral and 7 cases were bilateral. X-ray examination showed local prominence between ischium and pubis in all cases. Lamellar changes of the bone inhomogeneous in density with round translucence were found in 8 cases accompanied with intact cortex. Mild osseous hyperplasia was found in 8 cases without changes of periosteum and soft tissues. CT examination of 8 cases presented with local prominence between iscbium and pubis, translucence, cataclasm, discontiguous osteal cortex with irregular ends, sclerotic medullary cavity of honey surroundings, but no sequestration and changes of periosteum and soft tissues. The above-mentiooed X-ray features appeared in 14 cases among normal group, bilateral in 3 cases.

结果：病变组23例中，16例为单侧，7例为双侧。X线表现为坐骨耻骨结合处局限性骨膨隆，8例有层状改变，病变区内密度不均，有类圆形低密度透光影，骨皮质完整，8例周围骨质轻度增生，未见骨膜反应和软组织改变。8例CT表现为坐骨耻骨结合处局部膨大，其内有低密度透光区，有碎裂，骨皮质连续性中断，断端边缘欠整齐，邻近的髓腔轻度硬化，无明显的死骨和骨膜反应，邻近的软组织正常；正常组中14例出现上述X线改变，其中3例为双侧性。

At early stage after brain injury, there were a quantity of fibrous callus and cartilaginous callus formation in brain injury and fracture group and many neuropeptides immunoreactive nerve fibers in callus were found. Strong immunoreactivites of CGRP, SP, VIP, NPY, TOH occurred to osteogenitor cells and chondroblast, which proliferated in thickened endothecium.

脑损伤合并骨折组早期形成大量纤维骨痂和软骨骨痂，骨痂中神经肽免疫阳性神经纤维较多，明显增厚的骨膜内层骨祖细胞、幼稚的软骨细胞胞质内降钙素基因相关肽、P物质、血管活性肠肽、酪氨酸羟化酶、神经肽Y强阳性表达。

The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

扫描模式使用临床常用的颞骨螺旋扫描方式：管电压120 kV，准直宽度20×0.6 mm，视野200 mm，重建矩阵512×512，旋转时间1 s/r，重建层厚0.6 mm，重建间隔0.3 mm，分别改变管电流(380、300、200、160、120和80 mA)和螺距(0.8、1.0和1.2)进行扫描和重建，然后对颞骨进行横断面、冠状面和双斜面多平面重组，于重组后的横断层面图像上选取弓形下窝、鼓膜张肌腱、面神经隐窝、前庭导水管和锥隆起5个解剖结构，冠状面重组图像上选取盾板、横嵴、蜗窗、面神经的蛇眼征和锤骨外侧韧带5个解剖结构，双斜面重组图像上选取锤骨、砧骨、镫骨、上骨半规管和面神经管5个解剖结构，在双盲的情况下由放射学专家分别对各管电流和螺距下扫描的重组图像进行评分，随后进行统计学处理，从中筛选出满足诊断要求的最低管电流值和最大的螺距，分别采用患者25例(15耳)用该管电流值和螺距验证其可行性；然后利用模体分别测试各管电流和螺距下的图像的空间分辨率、噪声及其剂量长度积，并对测试所得参数数值进行比较和统计学处理。

At 12–15 years, Charnley reported continuous radiolucent demarcation around cemented cups in 14% of patients.40 The failure rate was greatest in young patients, and Barrack and colleagues reported 44% loosening of cemented sockets at 12 years in individuals younger than 50 years.54 Cementless acetabular cups are hemispherical in shape and most are entirely porous-coated for bone ingrowth.

术后12-15年时，Charnley在14%患者中发现骨水泥髋臼杯周边存在连续的透亮线。年轻患者中假体失败率最高，Barrack报道为小于50岁的患者中术后12年时44%发生骨水泥套松动。非骨水泥髋臼杯为半球型，大部分全层喷涂多孔表面以促进骨长入。

Wedge grafts or full-thickness grafts may be removed more easily with a power saw; this technique also is less traumatic than when an osteotome and mallet are used.

应用动力锯切取楔形植骨块或全层植骨块较为容易，并且比用锤和骨凿取骨创伤小。

Two pre-mixed pH dependent coating materials which have come into the market were choosen ,both made it.In quality evaluation,determined the disintegration latitude of product,established TLC of Psoralea corylifolia L.,.

在质量评价中，进行制剂崩解时限的测定，建立了补骨脂、肉豆蔻、吴茱萸的薄层鉴别以及补骨脂中补骨脂素、异补骨脂素的含量测定方法；并进行了制剂初步稳定性实验研究。

Effects of Adv-hBMP2 gene modify on the bone formation of tissue-engineered bone substitute. BMSCs of canine transferred by Adv-BMP2 gene expressed ALP in vitro and induced ectopic bone formation in nude mice. BMSCs adhered on the surface of FDB after 4hrs, expanded in 24hrs and proliferated in polylayer in 4d. FDB, combined with BMSCs transferred by Adv-BMP2 gene, induced bone formation in the subcutis of nude mice in 6 weeks.

结果：1.BMP-2基因修饰对组织工程化骨成骨的影响 BMSCs经Adv-BMP2基因转染后ALP染色强阳性、并在裸鼠肌肉形成异位骨组织；转基因的BMSCs与冻干骨复合后24小时即完全贴附生长，4天后复层生长并分泌大量胶原，植入裸鼠背部皮下6周后可见大量成骨，很少吸收，而单纯冻干骨或冻干骨复合BMSCs基本不成骨。2。

Results In the heated bone ,bone lacunae were empty ,no bone cells existed ,bone lamella was seen ,granular basophilia staining was seen in some parts of the lamella. In bone medulla , no cell existed , thrombosis occurred in some blood ,partial bone lamella disappeared.
