The present study was designed to investigate whether histamine is involved in the protective effect of carnosine on Aβ42-induced impairment in differentiated PC12 cells.

因此本实验的主要目的是检测肌肽对Aβ42诱导的神经兴奋性损伤是否具有保护作用，肌肽-组胺酸-组胺通路是否参与其保护机制，谷氨酸含量，NMDA受体表达及功能在这一过程中是否受到影响，最终阐明肌肽保护作用的具体机制。

The article reviews mechanism of action of caroid artery resulting from hypertension, especially debates vascular endothelial injury resulting from shear stress of vascular wall caused by hypertension, which can also affect vasopermeability by affecting the morphans, structure and function of vascular endothelium.

本文综述高血压引起颈动脉狭窄的发生机制，重点探讨血压对血管壁所造成的切应力引起的血管内皮细胞受损，通过影响血管内皮细胞的形态、结构和功能，并影响血管通透性，从而有助于脂质沉积的病理学机制。

The result of FLAC^3D numerical modeling indicates that the tension stress distributes along bedding weak layer and in cataclastic rock near slope surface; and potential sliding plane cuts through gradually.

Seen from the present study condition,the emotions of different valence load recruit partly overlapped brain areas;the studies on the recognition of facial expression show that different facial expressions activate different neural circuitries;the studies on induced emotions show that the anterior cingulated cortex seems to play a very important role in presenting experimentinduced emotions.

继James-Lange理论以后，Arnold，Lazzrus和Izard等又相继提出了不同的情绪理论，并且试图对情绪的中枢加工机制进行探讨和解释。但由于情绪本身的复杂性和方法学的限制，有关情绪的中枢加工过程和脑机制的探讨一直停留在较低的水平上。

Our findings suggest that increased brain activity in ipsilateral pons involved in trigeminal vascular reflex may be related to the pathogenesis of pain in cluster headache.Other brain regions known to be response to pain,such as cingulated gyrus and prefrontal cortex might be also involved in CH attack processing.
