Background: Peripheral nerve injury is common and serious in clinically. According to the nerve regeneration theory of nerve tropism, neural regeneration room became hot spot for treating nerve injury.Then keep distance between the proximal and distal severed stumps with different conduits and others substance which can promote nerve regeneration ,the room can provid a favourable environment for nerve regeneration. a series of empirical study indicated immunosuppressant FK506 can promote nerve regeneration, chitosan is polysaccharose natural biomaterial , Chitosan is prepared by the N-deacetylation of chitin.
背景:周围神经损伤在临床上比较常见,根据神经趋向性再生理论,神经再生室成为神经损伤治疗研究的热点,即在神经断端之间留出一定的间隙,并套以不同材料的鞘管及其它促进神经再生的物质,为周围神经再生创造良好的再生环境,一系列实验研究表明免疫抑制剂FK506有促进神经再生的作用。

We got the result: Bufo Raddei Strauch Tadpole (1) Bufo Raddei Strauch Tadpole was capable of lens regeneration, which originated from the epithelial cells at iris dorsal margin by dipigmentation.(2) Dipigmentation of Bufo Raddei Strauch by two methods: one was licked up by amoebocyte, the other one was flowed from the pigment cells.(3) In the lens regeneration cells of Bufo Raddei Strauch profiles of the mitochondria became complicated ribosome manifold, and the endoplasmic reticulum was cisternal dilation. During the process of deferentiation of lens fiber the cell nucleolus became little and chromatin shrinked.(4)The crystalline electrophoresis of Bufo Raddei Strauch Tadpole lens regeneration showed that during lens regeneration P-crystalline was expressed earliest then was γ-crystalline and α-crystallin, this result is consistent with newt.
结果表明:花背蟾蜍蝌蚪(1)具有晶状体再生的能力,其晶状体的再生来源于虹膜背缘的上皮细胞;(2)虹膜背缘去色素是转分化的前提,主要有两种方式:一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞,巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒;另一种方式是虹膜色素上皮细胞自身释放色素颗粒;(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化,核糖体增多,粗面内质网增多,晶状体纤维分化过程中细胞核逐渐凝聚;(4)SDS-PAGE电泳发现,花背蟾蜍蝌蚪晶状体再生中相关蛋白表达顺序与有尾类蝾螈相似,蛋白表达顺序依次是β-晶状体蛋白、γ-晶状体蛋白和α-晶状体蛋白,并且后两种蛋白几乎同时表达。

(1) cerebral ischemical reperfusion injury rats'limbs motor function is variable. Acupuncture could promote lims'functional recovery.(2) PCNA masc cells is visible in cerebral ischemical semidarkness region. There is cell regeneration phenomenon. Acupuncture could strengthen injury region's PCNA expression, could profit injury recovery and functional reconstruction.(3) In ischemia semidarkness region for the model group and acupuncture group, PCNA masc cells percentage of 14days group is lower than 7days group. Along with the recovery of injury, cell multiplication is weaken.(4) In cerebral ischemia semidarkness region, there is VEGF masc cells and regeneration phenomenon. Acupuncture could strengthen injury region's VEGF expression, could profit protection after injury and blood vessel regenerate.(5) In ischemia semidarkness region for the model group and acupuncture group, VEGF masc cells percentage of 14days group is lower than 7days group. Along with the recovery of semidarkness region, ischemia and anoxemia state is getting improved, and VEGF is reduce.(6) As there are PCNA and VEGF masc cells in brain injured region, we could conclude that, after brain ischemical reperfusion injury, there are blood vessel regeneration phenomenon. Acupuncture could promote blood vessel regeneration, recovery blood supply sufficiently and quickly, and promote the recovery of brain injury region.(7)The VEGF masc cells percentage of inhibitor group is lower than acupuncture group. It state that the effect of acupuncture promote VEGF is partly depend on the existing of eNOS.
实验结论:(1)脑缺血再灌注损伤后大鼠的肢体运动功能发生改变,针刺可以促进肢体功能恢复;(2)脑缺损伤区可见PCNA阳性细胞,存在细胞再生现象,针刺可以增强损伤区PCNA的表达,有利于损伤的修复和功能重建;(3)针刺组和模型组14d时缺血损伤区PCNA阳性细胞百分比低于7d组,随着损伤逐渐得到修复,细胞增殖现象减弱;(4)脑缺血损伤区可见VEGF阳性细胞,存在内皮型细胞再生现象,针刺可以增强损伤区VEGF的表达,有利于脑损伤后保护和缺血区血管再生;(5)针刺组和模型组14d时缺血损伤区VEGF阳性细胞百分比低于7d组,随着缺血损伤的修复,缺血缺氧状态得到改善,产生的VEGF减少;(6)由于脑损伤区同时出现PCNA阳性细胞和VEGF阳性细胞,前者是增殖细胞的标志,后者是促进血管再生的重要因子,可以推断,脑缺血再灌注损伤后脑内存在血管再生现象,针刺可以促进损伤区的血管再生,更迅速而充分的恢复损伤区的血供,促进脑损伤区的修复;(7)抑制剂针刺组脑损伤区VEGF阳性细胞百分比与针刺组相比有不同程度的降低,说明针刺促进缺血损伤区VEGF表达部分依赖eNOS的存在。

regeneration:再生
然而,丢失的组织细胞的修复可以是原来组织细胞的"完全复原"-------称之为"再生"(Regeneration);也可以是由非特异性的结缔组织增生来替代原有的组织细胞,形成"不完全复原"----称之为"修复"(Repair),不过,这两种不同的结果,其过程却是相同的.

regeneration:重生
华人基督徒大部份都关心传福音的事工,所以常用 "重生" 这个词,可是很多时候他们把 "重生" (regeneration) 与 "归主"或 "回转" (conversion) 混为一谈,这是很可惜的现象,导致颇混乱的思维.
