The process contains the proliferation of cells and the accumulation of extracellular matrix components.

这种增生膜的形成主要包括细胞的增生和细胞外基质的沉积。

To regulate tumor cells proliferation and metastasis. In many malignant tumors, CD44 has shed by MT1-MMP extracellularly, and causes the release of the soluble CD44, which facilitate the tumor cells motility.

在多种恶性肿瘤中，CD44分子胞外结构域可被膜结合型基质金属蛋白酶1(MT1-MMP)剪切，导致&可溶性&CD44分子的释放，此过程在细胞迁移中发挥重要作用。

ConclusionRemoval is the method of choice for patients with subdural extramedullary tumor. Early diagnosis and removal are key factors to get a good clinical effect.

结论手术切除肿瘤是治疗髓外硬膜下肿瘤的首选方法，早期确诊及时手术治疗是获得良好临床效果的关键。

Purpose To investigate the value of routine and Dynamic contrast-enhanced MR imaging in the histologic and vascularity assessment of intradural extramedullary tumors.

目的 探讨常规和动态增强MRI对髓外硬膜下肿瘤的组织学诊断和肿瘤富血管度的评价。

Radiologic diagnosis is often established by their intradural extramedullary location on magnetic resonance images.

通常通过MRI观察硬膜内和脊髓外定位进行放射学诊断。

Objective: To study the effect of early extubation on cardiovas and respiration under combined general and epidural anesthesia.

目的研究在硬膜外麻醉复合全身麻醉中早期气管拔管对心血管及呼吸等方面的影响，并评价其临床意义。

Several explants of RTM-derived tissue reconstructed in a fascial plane have been performed upon revision surgery and analyzed histologically.

几个外植体的RTM衍生组织重建，在筋膜飞机已执行调整后，手术及病理分析。

We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

Moreover, no significant changes in flagellar mobility, biofilm formation and production of extracellular cellulase and xylanase in vitro were observed in △rbfCxoo compared to PXO99A. Most importantly, the deletion mutation of rbfCxoo resulted in enhanced virulence and gene expression.

此外，△rbfCxoo鞭毛运动性、生物膜形成和胞外纤维素酶和木聚糖酶活性都无明显改变，但对水稻的致病性显著增强，毒性相关基因的表达也有所增加。

At left genuflex position and L3/4 or L2/3 intervertebral space in each patient, the needle entered following anesthesia from the intervertebral space into the epidural cavity, and needle core was extracted when feels nothing. Clear cerebrospinal fluid was effluent and collected for further use.

每例患者取左侧屈膝位，定位L3/4或L2/3椎间隙，麻醉后由椎间隙进硬膜外腔，再继续进针至有落空感时抽出针芯，有清亮脑脊液流出，留取脑脊液标本送检。
