六经气津互化论

气与津皆生于水谷,气生于水,水化于气,津即为水。由于气津互化的密切关系,故任何一方的改变,都会影响到另一方,即所谓水化于气,亦能病气;气生于水,亦能病水。因此,太阳经气可概括为两大功能,即卫外和气化,是由气津互化而体现的;阳明气津之间,表现为相互制约;少阳经的气津互化,关系到少阳气机的条达舒畅及三焦水道的通调运使;太阴脾气的健旺,可使津液化生有源;少阴心肾精血充沛,滋养有时,才可使心肾之气化生有源;而厥阴之气的条达顺畅,又可维持津液代谢的平衡状态。     

复方通络中药改善肥胖患者血管内皮细胞功能障碍研究

目的观察复方通络中药对单纯性肥胖患者血管内皮依赖性舒张功能障碍的干预效应，探讨其作用机制。方法应用高分辨血管超声检查选择血管内皮依赖性舒张功能障碍[以血流介导的肱动脉扩张率（FMD）表示]肥胖患者（65例），随机分为通络中药治疗组和对照组。治疗组32例，对照组33例。治疗组给予辛香疏络2号胶囊，3g／次，每日3次；对照组给予淀粉胶囊，3g／次，每日3次。共用药12周，分别测定用药前后FMD、肱动脉内径（D0），同时检测辛香疏络2号治疗前后患者血清总胆固醇（TC）、三酰甘油（TG）的变化。结果治疗后治疗组FMD较对照组明显增加（P〈0．01），TC、TG较治疗前及对照组明显下降（P〈0．01）。结论复方通络中药辛香疏络2号胶囊可明显改善肥胖患者血管内皮障碍，调节血脂可能是其改善血管内皮功能机制之一。     

家兔胆囊炎模型腹部循胆经高温反应与瘦素含量变化的观察

目的:研究兔胆囊炎模型腹部循胆经高温反应与瘦素含量的相关性。方法:实验用健康家兔分为正常对照组10只,胆囊炎模型组15只。胆总管缩窄结扎,于胆囊内注射大肠杆菌液0.1mL制作胆囊炎模型。造模后第3、7、11天分别沿胆经腹段,采用AGA-782型红外热像仪系统做体表热像图观察和记录。切取模型组循经高温反应部位皮下组织和对照组相应部位的组织,采用放射免疫法检测上清液内瘦素含量,并进行组织切片甲苯胺蓝染色的形态学观察。结果:体表红外检测结果显示模型组约有70%的动物在左右腹侧沿胆经的位置出现长短不一的循经高温反应(0.5～1.4℃)带或区,右侧多于左侧,而对照组则未显温度升高变化。模型组患侧和对侧循经高温反应部位的瘦素含量明显高于对照组(P0.01)。另外,通过观察组织切片,在红外热像仪所测的高温反应皮下组织内,脂肪细胞多沿血管排列;对照组脂肪细胞的分布显得较疏松,而在模型组发生循经高温反应的组织内,脂肪细胞排列显得拥挤。结论:脂肪细胞分泌的瘦素与循经高温反应有一定相关性。     

Visual spatial attention to stimuli presented on the vertical and horizontal meridian: An ERP study

In the first experiment, 48 subjects carried out a visual spatial attention task. Stimuli were presented at the vertical meridian, either above or below a fixation dot, and the subjects were instructed to attend to one of these stimulus positions and ignore the other position. In three different conditions, the distances between stimulus positions and fixation were 0.5°, 0.9°, and 1.3°. Subjects searched for the presence of prememorized target letters at the attended location: memory load was one or four items in different conditions. The P1/N1 enhancement typically found on the horizontal dimension was not observed on the vertical dimension. Instead, a positive shift of the attended compared with the unattended stimuli was found, which was most prominent at anterior electrodes. This positivity showed effects of the distance manipulation. The N2b-P3a effect of attention and the effect of memory load (search negativity) normally present in this kind of selective search task were also found. Reaction times were faster when attention was directed above fixation than when it was directed below fixation. The event-related potential data suggested that this difference could be attributed to a more efficient neglecting of irrelevant stimuli presented below fixation. In Experiment 2, we examined whether the absence of the P1/N1 enhancement as the result of spatial attention in Experiment 1 could be attributed to (a) the presentation of stimuli along the vertical meridian instead of along the horizontal meridian, (b) the use of midline electrodes instead of lateralized electrodes, and (c) the relatively small spatial separation between the relevant and irrelevant stimuli. Twelve subjects searched for the presence of a single target letter at an attended position in three different conditions. In two of the conditions the letters were presented to the left or right of fixation. The distance between fixation and the stimulus positions was 1.3° in one of these conditions and 3° in the other condition. In the third condition, the stimuli were presented at 3° above or below fixation. In all three conditions effects similar to those in Experiment 1 were observed. In addition, in all three conditions an enhancement of the P1 and N1 components was found at two lateral occipitotemporal electrodes.     

人皮肤内神经-肥大细胞联接在经络线上的发现 Ⅱ“传入性”神经-肥大细胞联接和伴同传出性轴突的薛旺细胞

本研究取材于人的皮肤,电镜常规方法处理。发现人皮肤内有两种类型的神经肥大细胞联接。提示可能分别为传出性和传入性的,或暂称为A型和B型联接,分别报告于上篇和本篇中。 B型联接的构造特点是,脱开薛旺鞘样长带包被的轴突来到肥大细胞近旁,突进细胞体中。轴突终末的一部分被胞质唇封盖起来,终末周围的轴膜与细胞质膜形成联接的双层膜。无肥大细胞表面皱褶参与其形成,无线粒体和显明的囊泡存在终末之内,无薛旺细胞包被轴突终末。薛旺细胞伴同A型联接出现,可与肥大细胞紧密接触。胞质内有狭缝系统和粗面内质网片断,能拖出长尾,估计将过渡为鞘膜。薛旺细胞不是间织细胞,这里的间织细胞应是成纤维细胞。
