Background and objective Although marked progress has been made in the treatment of acute myeloid leukemia,about 20%～40% patients with AML failed to get complete remission after standard induction chemotherapy. Furthmore, approximate 70% patients in CR will die because of relapse or refractory to therapy during post remission chemotherapy.

研究背景及目的：尽管目前急性髓系白血病(acute myeloid leukemia，AML)的治疗取得了显著的进步，但仍有20％～40％的患者经标准诱导治疗未能达到完全缓解(complete remission，CR)，即使获得CR的患者，在巩固化疗后仍有70％左右复发或发展为难治性急性髓系白血病而治疗无效死亡。

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。

The results indicated that 100μg/ml LPS had significant damage on the ultrastructure of HDPCs . After 5μg/ml Chinese nutgall water extract were added , the damage of HDPCs'ultrastructure was decreased significantly.

结果显示100μg/ml内毒素对牙髓细胞超微结构有不同程度的损伤，加入5μg/ml五倍子水提取物后，牙髓细胞超微结构损伤明显减轻，细胞器结构基本恢复正常。

The females incubated at 33 , their ovarium has powerful cortex, the germinal epithlium produce oocyte, its medulla degenerate into ovarian cavity. During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of ovary increase in quantity, they disintegrate after sexual differentiation. There are a lot of big grana in cells of ovary before sexual differentiation, in the course of sexual differentiation the quantity of the big grana decrease, while small grana increase and peakafter sexual differentiation. The males incubation at 26 , cortices of their testes degenerate into a thin albuginea. Medulla are formed by testicular cords in which scatter spermatogonium.

33℃下孵化的小龟卵巢皮质发达，由原始生殖细胞产生卵原细胞，髓质退化成为卵巢腔，分化时卵巢细胞的超微结构显示线粒体和内质网的数量大大增加，它们在分化结束后解体，分化前细胞内有较多的大颗粒，在分化中大颗粒减少，小颗粒增多，在分化后小颗粒达到最多。26℃下孵化的小龟精巢皮质退化成为一层薄的白膜，髓质有许多睾丸管构成，管腔内有散落排列的精原细胞。

Two weeks later, we measured the degree of the inclined plane and analyzed electrophysiological parameters such as latency, stimulus threshold and amplitude of MEP-C.

目前，多项研究表明OECs有促进轴突再生以及使脱髓鞘轴突重新髓鞘化的作用，因此有希望成为治疗脊髓损伤的一种新工具。

Results: Among the 47 cases, 33 cases were teeth pulpless tissue including 14 endodentically treated teeth and 14 cases were vital teeth with periodontitis, cracked tooth and occlusal traumatism.

结果：牙冠纵折多见后牙，以上颌第一磨牙为多见，其中无髓牙33例，牙折裂前有近一半曾作过根管治疗，活髓牙14例，存在不同程度的牙隐裂，牙周炎和咬合创伤。

Results:According to their anatomic location and vascular morphology,there were SDAVF in 3 cases,giant perimedullary AVF in one and intramedullary AVM in two.

结果：根据病变位置和血管形态、血流动力学改变，本组有3例符合硬膜动静脉瘘，1例为髓周的巨大AVF，2例为髓内型。

Results: According to their anaomic location and vascular morphology, there were SDAVF in 3 cases, giant Perimedullary AVF in one and intramdullare AVM in tWo.

结果：根据病变位置和血管形态、血流动力学改变，本组有3例符合硬膜动静脉瘘，l例为髓周的巨大AVF，2例为髓内型。

It suggested that SP may be involved in the regulatition of pulpal and periontal blood flow and in neurogenic inflammation.

牙髓及牙周组织中均有SP免疫阳性神经纤维的分布，并可能通过调节牙髓和牙周血管功能等途径，在其损伤和炎症反应中发挥作用。

Inside the gap for the pulp cavity, pulp cavity, there by the connective tissue, nerves and blood vessels formed, inflammation can cause severe pain.

内部的空隙为牙髓腔，腔中有牙髓，由结缔组织、神经和血管组成，发炎时可引起剧烈疼痛。
