Description
技术领域
本发明涉及医疗领域,具体涉及一种调节脑膜淋巴循环的方法。
背景技术
大脑内的毒性分子及代谢废物的引流通过很多不同的途径,例如脑脊液、血脑屏障、类淋巴系统等等。既往认为大脑内不存在内衬的淋巴内皮细胞,中枢神经系统缺乏淋巴管结构。近年来随着脑膜淋巴管结构的发现,使得其在中枢神经系统中的代谢物质的清除作用备受关注。目前对于脑膜淋巴通路参与病理性Aβ蛋白的清除已被证实;同时有研究表明阻断脑膜淋巴通路,加速休克后的颅内水肿。脑膜淋巴通路对于维持中枢神经系统紊态起着重要作用,但目前对于如何调节脑膜淋巴通路,改善大脑物质代谢循环的方法缺乏研究。现调节脑膜淋巴通路的方法,研究尚不明确。
发明内容
本发明的目的在于克服上述现有技术的不足之处而提供一种创新的调节脑内淋巴通路、改善大脑物质代谢的方法。
本发明提供的经颅磁刺激仪在改善脑膜淋巴循环中的应用。
优选地,所述改善脑膜淋巴循环具体为扩张脑膜淋巴管。
本发明还提供了一种调节脑膜淋巴循环的方法,包括以下步骤:将生物体的头部放置于经颅磁刺激仪圆形线圈的中心位置,启动仪器电源进行持续短阵快速脉冲经颅磁刺激。
优选地,所述持续短阵快速脉冲经颅磁刺激的参数为25%MSO,丛频率5Hz,丛内频率50Hz,每丛包含3个脉冲,刺激40秒,共600个脉冲。MSO表示仪器的最大输出强度.
优选地,所述放置位置为生物体的顶骨切面与线圈平面平行。
本发明的有益效果:本发明采用经颅磁刺激仪来调节脑膜淋巴循环,通过实验证明经颅磁刺激仪可以扩张脑膜淋巴管,促进淋巴循环,改善局部淋巴循环状况。
附图说明
图1为小鼠接受处理时经颅磁刺激仪摆放的位置示意图。
图2为实验组和对照组小鼠的脑膜淋巴管结构示意图(图A为完整顶骨脑膜淋巴管结构;图B和图C分别为上矢状窦和横窦视野下的淋巴管结构,免疫荧光蓝色代表DAPI,绿色代表淋巴管,scale bar=200um;图D和图E分别为上矢状窦和横窦视野下所测得的淋巴管直径统计图n=6)。
具体实施方式
为了更加简洁明了的展示本发明的技术方案、目的和优点,下面结合具体实施例及其附图对本发明做进一步的详细描述。
实施例1
本实施例提供一种调节脑膜淋巴循环的方法,包括以下具体步骤:
将12雄性C57BL/6小鼠(6-8w)随机等分成两组,实验组进行CTBS真性刺激(CTBS组),对照组进行CTBS假性刺激(Sham组)。调节好经颅磁刺激仪的参数(25%MSO-仪器最大输出强度,丛频率5Hz,丛内频率50Hz,每丛包含3个脉冲,刺激40秒,共600个脉冲)后,小鼠的放置位置如上图1所示,将小鼠的头皮位于圆形线圈的中心位置,顶骨切面与线圈平面平行,启动电源进行40秒的CTBS刺激。
实施例2检测经刺激后的效果
将实施例1的效果刺激完成后取材,将颅骨组织固定于4%的PFA溶液中,4℃冰箱过夜。将固定的颅骨组织取出,放入盛满冰PBS的玻璃皿中,用Dumont5#镊子轻轻剥离颅骨上的脑膜后,免疫荧光染色观察脑膜淋巴管结构。结果如图2所示,其中显示经CTBS刺激后实验组的小鼠脑膜淋巴管的直径较对照组要大,所述经CTBS刺激后脑膜淋巴管扩张,可促进淋巴微循环,改善局部淋巴循环状况。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
