OLIG2 is a transcription factor which could regulate the transcription of many oligodendrocyte/myelination related genes, and its expression level also was down-regulated in schizophrenia subjects. Therefore, OLIG2 is mostly like to be a risk gene of schizophrenia.

OLIG2是一个能够调控下游许多与少突触细胞/髓鞘发生相关的基因表达的转录因子，且OLIG2的表达水平在精神分裂症患者体内也明显下降，因此，OLIG2极有可能是精神分裂症的致病基因。

Although both of FDRMADS7 and FDRMADS8 wereexpressed in the root, they have different expression pattern.The transcripts of FDRMADS7 weredetected throughout the root,especially the expression in the root meristem was the highest.However,the expression of FDRMADS8 was mainly localized in elongation and mature rigion.No apparent expression signal was detected in the root cap, root meristem and pericycle cells.

虽然FDRMADS7和FDRMADS8都在根中表达，但它们在根中的表达模式也不相同：FDRMADS7在根中到处表达，尤以生长点处表达量最高；而FDRMADS8在伸长区和根毛区的皮层中有大量表达，在根冠，根尖分生区和根毛区的中柱鞘细胞中却无明显表达，暗示它们在根中行使的功能也不相同。

Neurothekeoma and plexiform fibrohistiocytic tumor are dermal neoplasms that share many clinical and histologic features and whose histogenesis is equally disputed.

神经鞘黏液瘤和丛状纤维组织细胞性肿瘤好发于皮肤，两者的临床特点和组织学特征有许多相同之处，但两者的组织发生仍具争议。

Electronic microscopic observations showed that the swollen mitochondria with cristae blurred appeared in some pyramidal cells. Some pyramidal cells showed degenerative changes with some disappeared endoplastic reticula and ribose nuclear protein and increased lysosomes. The amount of extends endothelial projections going to the lumen of capillaries were increased.

同时伴有超微结构的改变，如神经细胞线粒体肿胀，内质网扩张，染色质凝集成块状，毛细血管外间隙扩大，髓鞘变性坏死，微管排列紊乱，小胶质细胞有吞噬变性坏死的神经纤维成分等。

Result: Schwann-like cells disperse in the hole of nerve graft at oneweek under Scanning Electronic Microscope, the processes of thesatellite-like cells adhere to the wall of graft.There was no statisticaldifference of activity of cells in both group(P＞0.05) using MTT. At 12weeks,the result of appearance, histology and TEM were similar, therewere no statistical difference in SFI%, NEP and quantitative analysis ofrecovery rate of myelinated fiber populations, diameter of myelinatedfiber and thickness of myelin sheat.

结果：1w后扫描电镜下可见接种的类Schwann细胞分散在材料表面的孔隙内，细胞形态为星状，细胞突起与支架管壁粘附；MTT法测定细胞活性示神经支架组在各时间点与对照组无显著性差异P＞0.05；12w时两组动物坐骨神经外观、组织学光镜观察、透射电镜观察结果相似、两组坐骨神经功能指数恢复率、神经电生理、再生有髓神经纤维计数恢复率、神经纤维直径恢复率、髓鞘厚度恢复率等指标相比无显著性差异(P＞0.05)。

Bipolaris sorokiniana may affect turf grass to cause leaf spot, bud rot, seedling blight, root rot, sheath rot. The temperature range of colony growth is 10～40℃, the optimum 25℃. Conidia can germinate in the temperature range of 20～35℃, and germinate best at 28℃; Conidia germinate well on slide water surface, contrary to other different methods, and they can germinate well under given air condition, but germination is not strict with nutrition. The inhibiting test of 8 kinds of fungicide showed Sporgon 50WP was most effective, and the inhibiting effect of the others was well to the conidia germination.

Bipolaris sorokiniana能浸染草坪禾草叶片形成梭形病斑，并可导致芽腐、苗枯、根腐、茎基腐、鞘腐等症状；病原菌在10～40℃下能够生长，最适生长温度为25℃；病原菌分生孢子在不同萌发条件中以水平萌发较好；分生孢子萌发需要空气条件，但对营养要求不严格；在20～35℃下分生孢子均可萌发，以28℃下萌发最好；八种不同药剂对病原菌的抑制效果表明，50%施保功可湿性粉剂1500倍液效果较好，其抑菌圈直径和抑制分生孢子萌发率分别为46.2mm和81.3%，其他几种药剂对孢子萌发也有较好的抑制作用。

Sinocarum is usually circumscribed by a suite of characters: rhizome elongate, petiole sheaths expanded, petals obtuse at apex, clawed at base, flowers radiant, and fruit oblong-ovoid.

Sinocarum 通常由一套特征限定：根状茎拉长，叶柄鞘膨大的，花瓣在先端钝，在基部有瓣爪，花辐射状，和果长圆状卵球形的。

Leaves 3 or 4 per ultimate branch; sheath straw-colored, glabrous; auricles and oral setae absent; ligule purple-red, ca. 2 mm; pseudopetiole ca. 2 mm; blade elliptic-lanceolate, 4–20 × 2–2.9 cm, secondary veins 4–8-paired, base cuneate, margin serrulate, apex acuminate.

每末级的分枝留下3或4；鞘稻草色，无毛；叶耳和口头的刚毛无；叶舌紫红色，约2毫米；假梗约2毫米；叶片椭圆状披针形， 4-20 * 2-2.9 厘米，次脉4-8配对，基部楔形，边缘有细锯齿，先端渐尖。

In a normal spine, the spinal dura mater is a loose sheath that is anchored in the ertebral canal by the nere roots and by its attachment to the periosteum in two places: one at the foramen magnum and the dorsal surfaces of C2 and C3 and the other at the coccyx .

在正常脊柱，硬脊膜是松散的鞘性结松，其靠神经根和两个骨膜驸着部位固定在椎管内，一处在枕大孔和C2及C3，另一处在尾骨，其余部分只是悬吊和衬附于椎管内，其间有硬膜外脂肪、静脉丛和疏松的结缔组织。

This one mode pays close attention to network credence foundation of the businessman very much.
