Anatomical study proved:①.4~8 nutritional vessels of sural nerve –small saphenous vein were the intermuscular perforators of peroneal artery, the furthermost one located at(1.0±1.3)cm above the tip of external malleolus with diameter (0.6±0.2)mm;②.2~6 musculocutaneous perforators were given off by the artery of outer head of gastrocnemius muscle to supply nutrition to the sural nerve-small saphenous vein;③.intermuscular perforators from peroneal artery supplied blood to fibula and outer head of soleus muscle.the perforators with an average outer diameter of （1.3-1.6）cm gave off cutaneous branch ,fascial branch and nutritional vessels to the sural nerve-small saphenous vein,which formed the vessel chain of the sural nerve-small saphenous vein ,sub-fascial and suprafascial vessel net.

结果：1、解剖实验证实：①、腓肠神经-小隐静脉营养血管来自腓动脉肌间隔穿支4～8支，最远的跟外侧动脉穿支距外踝尖上(1.0±1.3)cm，外径(0.6±0.2)mm。②、腓肠肌外侧头动脉沿途发2-6支的肌皮穿支营养腓肠神经-小隐静脉。③、腓动脉肌间隔穿支营养腓骨、比目鱼肌外侧半。上述穿皮支平均外径在0.3～1.6mm，发出皮支、筋膜支、腓肠神经-小隐静脉营养血管，形成腓肠神经-小隐静脉血管链以及深、浅筋膜血管网。

Methods Microanatomy and red-and-blue latex injection transpa rency method were applied to study ①The medial antebrachial cutaneous nerve, the lateral antebrachial cutaneous nerve and their nutrient vessels;②The relationship between the basilic vein and MACN and its nutrient vessels; and ③The relationship between the cephalic vein and LACN and its nutrient vess els.

用显微解剖法、标本双色透明法观测前臂内侧皮神经血供、贵要静脉与前臂内侧皮神经及其营养血管的关系和前臂外侧皮神经的血供、头静脉与前臂外侧皮神经及其营养血管的关系。

Nerve stem cell can be differentiation into astroblast, oligodendrocyte and nerve cell induced by factors.

神经干细胞的增殖分化可受各种因素的影响，目前已知，许多细胞因子，生长因子，营养因子以及细胞外环境等因素的作用，可诱导神经干细胞向不同的终末细胞分化，若能在体外分离培养神经干细胞并在促分化因子的作用下，诱导神经干细胞向某一特定方向分化，将为干细胞的分化机制提供有力的实验依据。

there are longitudinal vascular networks interweaved inside and around the great saphenous vein and saphenous nerve on the medial foot .

足内侧大隐静脉—隐神经内部及其周围存在着纵行的血管网，这些血管在营养大隐静脉及隐神经的同时也营养邻近皮肤。

MAIN OUTCOME MEASURES: Morphology change of spinal cord was detected by light microscope and electronmicroscope, secreted brain-derived neurotrophic factor was measured by immunohistochemistry and PT-PCR, and the combine behavioral score was used to assess the functional recovery of spinal cord. RESULTS: Immunohistochemistry result showed that OECs transplantation could partly reduce the number of apoptosis cells in spinal gray matter, delay cells reduction in spinal white matter, and accelerate the medullary sheath repair and regeneration.

主要观察指标：应用光学显微镜、电子显微镜观察脊髓形态的变化，采用免疫组织化学、PT-PCR 的方法检测脊髓组织脑源性神经营养因子的分泌，以改良的Gale联合行为评分法对脊髓功能进行评定，结果：免疫组织化学检测显示，嗅鞘细胞移植能部分改善大鼠脊髓灰质神经细胞的凋亡程度，延缓白质神经纤维的减少，促进髓鞘的修复与再生。

There is a possibility that the onset of PD is associated with BDNF genetic polymorphisms.

帕金森病的发生可能与脑源性神经营养因子基因多态性有关。

目的 探讨应用外源性睫状神经营养因子对成年猫面神经损伤后的再生修复作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
