椎管内髓外硬膜下神经鞘瘤的MRI特征，有助于椎管肿瘤的鉴别诊断，尤其是伴有瘤内分隔性周围强化，应提示神经鞘瘤。

Routine MR imaging can diagnose the majority of intradural extramedullary tumors.Dynamic contrast-enhanced MR imaging are helpful in the histologic diagnosis and assessment of tumors vascularity.

常规MRI能鉴别大多数髓外硬膜下肿瘤的性质，动态增强MRI有助于肿瘤定性诊断和肿瘤富血管度的评价。

Methods The routine MR imaging was performed on 114 intradural extramedullary tumors with a 1.0 Tesla MR unit.Rank correlation and regression coefficent were analyzed for MR characteristics of neurilemmomas、neurofibromas and meningiomas.Dynamic spin-echo MR imaging was performed on 23 cases types of contrast enhancement ratio-time curves were analyzed.

使用1.0 Tesla MRI系统(Magnetom Impact，Siemens)对114例髓外硬膜下肿瘤进行常规扫描，对常见肿瘤(神经鞘瘤、神经纤维瘤、脊膜瘤)的MRI征象进行等级相关和回归系数分析，同时对23例肿瘤进行SE(200/15)序列动态增强扫描，分析CER-T曲线类型。

To appraise effect of the home-made recombinant human granulocyte colony stimulating factor in the mobilization peripheral blood stem cells. From 2001 to 2005, 20 patients undergoing autologous peripheral blood stem cell transplantation were enrolled, 11 males, 9 females, 11 patients with acute myelocytic leukemia, 5 patients with acute lymphocyte leukemia, 3 patients with malignant lymphoma, and 1 patient with multiple myeloma.

为评估国产重组人粒细胞集落刺激因子在动员外周造血干细胞的效果，选择2001/2005收治的20例自体外周血造血干细胞移植患者，男11例，女9例，其中急性髓细胞白血病11例，急性淋巴细胞白血病5例，恶性淋巴瘤3例，多发性骨髓瘤1例。

Methods: Nonadherent cells from bone marrow or peripheral blood mononuclear cells of 8 patients with chronic myeloid leukemia were cultured with rhGM- CSF and rhIL- 4. The cytokines were supplemented every three days. RhTNF-α was used at the ninth day. All the cells were harvested at the twelfth day.

从8例慢性髓性白血病患者的骨髓或外周血中获取非贴壁细胞，利用细胞因子(rhGM蛳CSF、rhIL蛳4、rhTNF蛳α)联合培养，每3 d补充新的细胞因子，其中rhTNF蛳α为第9天添加，第12天收获细胞。

All of those confirmed the odontogenetic ability of adipose-derived stem cells, offered theory and experimental basis for the abundant seed cells in tooth tissue engineering, construct new research model for the micro-environment of the odontogenesis in vitro and vivo.

目的 本研究通过酶消化法分离培养脂肪干细胞，运用牙胚细胞条件培养液体外诱导脂肪干细胞向成牙本质样细胞分化，再将脂肪干细胞与成釉器上皮细胞混合接种入体内建立牙髓-牙本质复合体模型，证实大鼠脂肪干细胞的成牙潜能，为牙齿组织工程化研究获得大量、稳定、可靠的种子细胞提供理论和实验依据；并为体内、外成牙微环境的机理研究构建新的模型。

I.. The virions were observed in the cylindrical cell at 9 h p. i.. The intact virions probably penetrated through the peritrophic membrane, then absorbed and invaded the microvilli for infecting the cylindrical cells.

作者认为病毒入侵是以整个病毒粒子穿越中肠围食膜，吸附并进入微绒毛，感染圆筒形细胞，与前入病毒入侵只是髓核进入细胞，而病毒衣壳仍留在细胞外的推测不同。

The ventrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

D 区是紧邻 Barrington's 核腹侧的一团神经元，它发出纤维投射至腰骶髓 Ounf 核的背外侧群，而 Ounf 核的背外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

The follow-up periods were various from 6m to 21m. The apical MTA barrier technique was used to manage pulpless permanent teeth with incomplete root formation. The postoperative radiographs showed complete repair of periradicular tissue in 5 of 7 teeth and improvement obviously in other 2 teeth. Only one case (1 tooth) had a 3mm periodontal pocket in four perforation repair cases. The lesion at the perforation sites was improved obviously.

追踪观察时间为6-21月。4例穿孔修补的病例，均为延迟修补，除一例为根尖1／3处的病理性吸收外，其余患牙的穿孔部位位于牙根的冠1／3或根分叉处，一例6m复查时有3mm的牙周袋形成，其余患牙骨吸收暗影均明显缩小。7例根尖发育不全并无髓牙的病例均为成人，5例根尖暗影完全消失，2例明显缩小。

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%.
