Methods Totally 900 patients with traumatic epidural haematoma who were treated with drilling skull plus urokinase were reviewed.

总结900例颅骨钻孔结合尿激酶微创治疗外伤性硬膜外血肿的临床资料。

Objective To discuss the feasibility of minimally invasive treatment of traumatic epidural haematoma with drilling skull plus urokinase.

目的 探讨颅骨钻孔结合尿激酶微创治疗外伤性硬膜外血肿的可行性。

Objective To evaluate the characteristics of spinal epidural and subdural haematomas in clinical situation and MRI diagnosis and therapeutic outcome.

结合相关文献，回顾性分析 7例自发性硬脊膜外血肿和 1例自发性硬膜下血肿的流行病学、发病机制、部位、临床特征、神经功能状态，以及手术、保守治疗和预后。

Its difference was significant. The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of proliferating group, involuting group , vascular malformation group and normal skin group involuting group were respectively10%、28%、6%、5%.

其差别具有显著性意义 1、增生期血管瘤组织中，MMP-2表达明显升高，可以认为MMP-2通过降解血管基膜和细胞外基质促进小儿血管瘤血管形成，从而促进血管瘤增殖。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

The load carrying capacity of the ferrofluid lubricating films can be controlled directly by means of the applied magnetic field, since the viscosity of the ferrofluid increases in the case of magnetic field.

利用外加磁场可以直接调节铁磁流体润滑膜的承载能力，因为在外磁场中铁磁流体的粘度增大。

The disturbance of the equilibration between MMPs and TIMPs is associated with the secondary brain injury after acute

研究表明，MMPs不但能够降解微血管基底膜和细胞外基质，与血管源性脑水肿密切相关；而且参与神经系

Methods:Thirty-one patients were not given any drugs before anesthesia and plasma level of neuropeptide Y was measured with radioimmunoassay.

采用放射免疫分析法测定了31例择期上腹部手术病人胸段硬膜外麻醉前后血浆NPY的含量。

Malignant cranial nerve sheath tumors are rare and are associated with the same poor prognosis as those of spinal nerves at other sites.

恶性外周神经鞘膜瘤很稀少，并同发生在脊神经其他部位的肿瘤一样预后不良。

Very rarely, features of high grade osteosarcoma, leiomyosarcoma, chondrosarcoma, rhabdomyosarcoma and malignant peripheral nerve sheath tumor are found.

罕见的情况下可以找见高级别骨肉瘤、平滑肌肉瘤、软骨肉瘤、横纹肌肉瘤和恶性外周神经鞘膜瘤的特征。
