  The aim of the present study is to probe candidate genes which were involved in the electro-acupuncture (EA) analgesia and to understand the molecular basis of the individual difference of EA analgesia in rats.EA stimulation at the ST36 acupoints (Zusanli) was applied for 1 h at 1 Hz and nociceptive sensitivity was assessed by recording the tail-flick latency (TFL) induced by radiant heat.Responders and non-responders were determined by Pain Threshold Increase Rate (PTIR) in which the PTIR of responders is more than 30% while the PTIR of non-responders is less than 25% of control.We compared hypothalamus transcriptional profiles of responders with that of non-responders using oligonucleotide microarray.

稳定可靠的研究模型是取得真实实验结果的基础和关键。用线栓大鼠大脑中动脉(MCAO)法制作的实验性局灶性脑缺血/再灌注模型是被广泛采用的研究脑缺血病理生理过程和相关的脑缺血损伤的分子机制以及评价干预措施效应的比较理想的研究模型。但该模型也被认为由于多种原因导致其存在稳定性差,变异度大的缺点。有鉴于此,我们综合应用激光多普勒微循环检测仪的动态检测和神经行为学评分、脑梗死体积测定和模型大鼠24小时内死亡

本实验室以往研究发现L-型钙通道功能改变在脑缺血后海马神经元死亡过程中发挥了重要的作用,然而其作用的机理目前仍不清楚。为探讨L-型钙通道参与缺血性神经细胞死亡的机制,寻找其可能的下游信号分子及转导通路,我们利用GST-pull down技术研究大鼠海马L-型钙通道相互作用蛋白在短暂性前脑缺血后的变化。根据GenBank登录的α1C基因的编码核苷酸序列,设计合成针对其C末端(1808-2139)编码
