Project description:Background: Electroacupuncture (EA) were progressively gained popularity in the treatment of neurological disorders such as ischaemic brain injury in recent years. But the therapeutic mechanisms of EA are yet not well addressed. This research aims to explore the effect of electroacupuncture stimulation of Lung Meridian of Hand-Taiyin on synaptic plasticity in rats with cerebral ischemia-reperfusion injury based on Transcriptomics Methods: Rats were randomly divided into sham operation group, model group and EA group. Rats in the model group and the EA group were prepared for the middle cerebral artery occlusion/reperfusion (MCAO/R) model. In the EA group, the representative acupoints of the Lung Meridian of Hand-Taiyin (Tianfu acupoints, Chize acupoints, Kongzui acupoints and Taiyuan acupoints) were selected for electroacupuncture stimulation. Transcriptomics was performed after the intervention.

Project description:The electroacupuncture-induced analgesic effect has been used widely to alleviate diverse pains. However, significant individual variations in analgesic effect of EA for both experiments and clinics were reported. According to the sensitivity of the analgesic response to EA stimulation, the subjects could be categorized into high responders (HR) and non responders (NR). However, the molecular mechanism of individual variability in the analgesic response to acupuncture stimulation is still uncertain. This study aims to investigate the potential gene expression in arcuate nucleus induced by 2Hz/100Hz electroacupuncture in HR and NR rats. Rats were given 2Hz or 100Hz electroacupuncture for 30 min and using cDNA microarrays to compare different gene expression in arcuate nucleus. Rats were exposed to different frequencies (2Hz or 100Hz) electroacupuncture stimulation for 30 min and nociceptive testing and returned to home cages for 1 hour before sacrificed. According to the sensitivity of the analgesic response to 2Hz or 100Hz EA stimulation, the rats divided into four groups: 2Hz-HR group, 2Hz-NR group, 100Hz-HR group and 100Hz-NR group. Subsequently analyzed their dorsal horn transcript profile using cDNA microarrays, the rats were without receiving electroacupuncture as control. The tissue of arcuate nucleus (Arc) of three rats was selected for transcript analysis in each group. The three control rats were mixed and labeled with cy5, each rat of experiment groups was labeled with cy3.

Project description:The electroacupuncture-induced analgesic effect has been used widely to alleviate diverse pains. However, significant individual variations in analgesic effect of EA for both experiments and clinics were reported. According to the sensitivity of the analgesic response to EA stimulation, the subjects could be categorized into high responders (HR) and low responders (LR). However, the molecular mechanism of individual variability in the analgesic response to acupuncture stimulation is still uncertain. This study aims to investigate the potential gene expression in spinal dorsal horn induced by 2Hz/100Hz electroacupuncture in HR and LR rats. Rats were given 2Hz or 100Hz electroacupuncture for 30 min and using cDNA microarrays to compare different gene expression in dorsal horn. Transcriptome profiling analysis found that some co-regulated genes related with electroacupuncture or 2Hz or 100Hz freqencies. These co-regulated genes were plasticity-related by GO analysis. We also found some special regulated genes in HR vs. LR in 2Hz/100Hz electroacupuncture stimulation. These results suggested that neurotransmitter system and cytokine different between HR with LR in 2Hz electroacupuncture. But in 100Hz electroacupunture, there were many different regulated genes related with ribosome between HR with LR, which needs more studies to research the function and may play an important role in HR vs. LR by 100Hz electroacupuncture.

The tissue of dorsal horn (DH) of the fifth and sixth lumbar (L5 and L6) of four or five rats were selected for transcript analysis in each group. The five control rats were mixed and labeled with cy5, each rat of experiment groups was labeled with cy3.

Project description:Acupuncture treatment is based on acupoint stimulation; however, the biological basis is not understood. We stimulated one acupoint with catgut embedding (CEP) for 8 weeks and then used isobaric tags for relative and absolute quantitation to screen proteins with altered expression in adjacent acupoints of Sprague Dawley rats. The expression levels of 10 proteins, including kininogen (KNG), consistently changed >1.5-fold in all three acupoints in CEP versus sham CEP-treated rats. Eight-week, but not 3-day, CEP treatment enhanced KNG expression. The enhanced KNG expression among small vessels in the subcutaneous layer was revealed via immunofluorescence. Nitric oxide synthesis was enhanced similar to KNG. These findings uncover biological changes at acupoints and suggest the critical role of the KNG–nitric oxide signaling pathway in acupoint activation.
