皮节

For older patients who are cooperative, regional techniques, especially subarachnoid and epidural block, can be used effectively and safely for procedures requiring anesthesia below the T-8 dermatome.

老年人如能合作，区域麻醉特别是蛛网膜下阻滞或硬膜外麻醉，为麻醉品面在胸8皮节以下的手术操作提供麻醉是安全有效的。

Compression of nerve roots often produces objective sensory changes early, with paresthesia and loss of sensating detectable in the affected dermatome.

神经根受压常很早即产生客观的感觉变化，在受影响的皮节区有感觉异常及感觉缺失，神经根持续受压，可发生运动肌无力，若累及腰4神根，可见膝腱反射减弱和轻度股四头肌无力，小腿肌肉感觉减退。

The CPT values in the affected leg in patient group were significant higher than those in control group at all frequencies. The CPT values in contralateral leg in patient group were significant higher than those in control group at 5Hz whereas there were no significant differences at 250Hz and 2000Hz. The CPT values in affected leg in patient group were significant higher than those in contralateral leg at 250Hz and 2000Hz whereas there were no significant differences at 5Hz. All the CPT values showed the same linear decrease from the dermatome of the compressed root to the dermatomes of the contralateral neighbor dematom.

在用CPT监测8例腰骶单神经根病组患侧和健侧及与正常对照组的不同直径感觉神经纤维功能的研究中发现压迫皮节和其临近皮节的所有频率CPT值无任何显著性差别；患者压迫侧的2000Hz及250HzCPT值及压迫侧和对侧的5HzCPT值与正常对照组都有显著性差别；患者组5HzCPT值患侧和对侧无差别，其他两组均有显著性差别；不管有无显著性差别，神经根病患者组各皮节三频率CPT值均按照压迫皮节，临近皮节，压迫对侧皮节，压迫对侧临近皮节的顺序减小，说明在腰骶单神经根病中Aβ纤维及Aδ纤维及无髓C纤维均受累。

Compre ion of nerve roots often produces objective se ory changes early, with paresthesia and lo of se ating detectable in the affected dermatome. With continued root compre ion. Motor weakne may develop. With involvement of the L4 root, the patellar tendon reflex may be diminished and slight quadrice weakne may be o erved.

神经根受压常很早即产生客观的感觉变化，在受影响的皮节区有感觉异常及感觉缺失，神经根持续受压，可发生运动肌无力，若累及腰4神根，可见膝腱反射减弱和轻度股四头肌无力，小腿肌肉感觉减退。

Many animals form a number of temporary structures along their anterior-posterior axis during embryonic development – somites. Cells in somites differentiate to form the sclerotome, the dermotome and myotome.

脊椎动物在胚胎发育的过程中沿身体前后轴形成一定数目的暂时性结构—体节，随着胚胎的继续发育每个体节分化成为生骨节，生皮节和生肌节，继而生成各种组织。

We report the case of a 45-year-old woman with opticospinal type multiple sclerosis with recent cutaneous herpes zoster and right shoulder girdle weakness.

我们报告一个45岁的视神经脊髓型多发性硬化症患者，在右侧颈第五、六皮节带状疱疹发疹后，发生右肩无力。

Results:Abnormality was located on base stanza area in 15cases,skin and medulla area in 5 cases,cerebella in 3 cases.

结果：病变位于基底节区15例，皮、髓质区5例，小脑3例；基底节区病变呈斑片状短T1信号，皮

At histopathologic analysis, neuronal tumors are usually classified as pure neuronal cell tumors (gangliocytoma, Lhermitte-Duclos disease , central neurocytoma) and mixed neuronal-glial tumors (ganglioglioma, desmoplastic infantile ganglioglioma, dysembryoplastic neuroepithelial tumor, ganglioneuroma).

根据组织病理学的分析，神经元肿瘤通常被分为：单纯的神经元细胞肿瘤（神经节细胞瘤，Lhermitte-Duclos 病〔发育不良性小脑神经节细胞〕瘤），中枢神经细胞瘤）和混合性的神经元-胶质肿瘤（神经节神经胶质瘤，成结缔组织性婴儿节细胞胶质瘤，胚胎发育不良性神经上皮瘤，神经节瘤）。
