目的:电针抗脑缺血和恢复神经功能的作用勿庸置疑,从国内外电针对脑缺血损伤后神经元轴突干预作用的研究发展现状出发,就电针对轴突生长与抑制因子干预作用等方面的进展作一综述。资料来源:应用计算机检索Medline1995-01/2006-04的与脑卒中早期神经再生相关文献,检索词“electricneedle,axongrowthandinhibitivefactor”,限定文献语种为英文;同时计算机检索CNKI数据库1999-01/2005-04期间的与电针对轴突生长与抑制因子影响的相关文献,检索词“电针,轴突生长与抑制因子”,限定文献语种为中文。资料选择:从资料中选取包括治疗组和对照组的文献,然后选择是随机临床试验的研究。纳入标准:①脑卒中早期康复治疗的随机对照临床试验。②治疗组为早期康复治疗组。③对照组为不进行早期康复治疗组。④患者年龄<80岁。⑤患者均为首次卒中。排除标准:综述类文献、没有对照组的文献。资料提炼:共收集到54篇关于脑卒中早期神经再生和电针对轴突生长与抑制因子影响的文献,29篇为随机临床试验纳入综述。排除的25篇中11篇是重复的同一研究,14篇为Meta分析研究。共32个试验包括3472例患者。资料综合:轴突生长与抑制因子在中枢神经系统神经再生的突出作用是调控轴突导向、引导轴突生长,协助构建精确的神经网络形成,在脑缺血损伤的病理生理过程发挥重要的双重功能。①脑缺血与神经再生:神经再生可以看成是成年脑内神经发育过程的重新启动,是特定条件下神经元突起的再生。轴突生长抑制性蛋白在正常发育过程中主要参与调控轴突导向、引导轴突生长,协助构建精确的神经网络。在神经损伤时表达则阻止成年动物神经再生的活性和轴突再生。轴突生长除受生长抑制蛋白调控外,还受轴突生长因子的作用,神经生长相关蛋白是其中的代表。②电针与轴突生长相关因子:针刺可增加碱性成纤维细胞生长因子、胶质细胞源性神经营养因子的表达,促进短暂性大脑中动脉闭塞大鼠血管内皮生长因子星形胶质细胞的表达和梗塞大脑血管的形成,增强急性脑缺血大鼠梗死灶周围血管内皮生长因子、Flt-1的表达。结论:神经再生是特定条件下神经元突起的再生,与生长抑制蛋白的调控和轴突生长因子的作用密切相关,电针通过调控轴突生长因子而促进中枢神经功能恢复。

背景:临床及动物实验证实脑溢安能促进脑出血急性期血肿吸收及神经功能恢复,提高生活质量。目的:观察脑溢安血清对体外缺氧培养的大鼠脑微血管内皮细胞转化生长因子β1mRNA表达的影响。方法:用分离培养的大鼠脑微血管内皮细胞移入厌氧培养箱培养18h建立缺氧损伤模型,并随机分为正常组、模型组、正常血清组及含脑溢安血清组。正常组为同一批正常培养的脑微血管内皮细胞;模型组将正常培养的细胞放入厌氧培养箱内培养18h;正常血清对照组细胞在培养液中加5%正常血清后,放入厌氧培养箱中培养18h;脑溢安血清组细胞在培养液中加5%脑溢安血清后,放入厌氧培养箱内培养18h。结果与结论:缺氧培养使脑微血管内皮细胞存活数量减少,其表达的转化生长因子β1mRNA增强,而脑溢安血清能明显增加脑微血管内皮细胞存活数量,降低转化生长因子β1mRNA表达水平(P<0.05)。说明脑溢安血清下调转化生长因子β1mRNA的表达可能是其抑制脑微血管内皮细胞的凋亡对缺氧损伤脑微血管内皮细胞的保护作用机制之一。

目的:探讨脑出血后炎症反应机制及核因子-κB(NF-κB)与细胞间粘附分子-1(ICAM-1)间表达的关系。方法:建立大鼠脑出血模型及过氧化氢损伤大鼠脑微血管内皮细胞的模型,分别采用免疫组化、原位杂交、免疫细胞化学及Western blotting方法观察NF-κB和ICAM-1的表达。结果:大鼠脑出血后NF-κB及ICAM-1表达均增强,ICAM-1的表达高峰(1 d)先于NF-κB(4 d),但在体外实验中,过氧化氢损伤后即刻大鼠脑微血管内皮细胞中NF-κB表达即增加,2 h后ICAM-1表达也上调,NF-κB的抑制剂吡咯烷二硫氨基甲酸(PDTC)可下调NF-κB及ICAM-1表达。结论:在活性氧损伤中NF-κB作为ICAM-1的活化因子,可上调ICAM-1表达,但在脑出血这一复杂的病理生理变化中,尚有其它因素参与对NF-κB及ICAM-1表达的调控。

For the applications of the frequency comb in microresonators,it is essential to obtain a fully frequency-stabilized microcomb laser *** this study,we present a system for generating a fully atom-referenced stabilized soliton *** pump light around 1560.48 nm is locked to an ultra-low-expansion(ULE)*** pump light is then frequency-doubled and referenced to the atomic transition *** repetition rate of the soliton microcomb is injection-locked to an atomic-clockstabilized radio frequency(RF)source,leading to mHz stabilization at 1 *** a result,all comb lines have been frequencystabilized based on the atomic reference and the ULE cavity,achieving a very high precision of approximately 18 Hz at 1 s,corresponding to the frequency stability of 9.5×10^(-14).Our approach provides a fully stabilized microcomb experiment scheme with no requirement of f-2f technique,which could be easily implemented and generalized to various photonic platforms,thus paving the way towards the ultraprecise optical sources for high precision spectroscopy.
