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.

Subsequently analyzed their dorsal horn transcript profile using cDNA microarrays, the rats were without receiving electroacupuncture as control. 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:Postoperative ileus (POI) often occurs and prolongs hospital stay, which costs expensive. Electroacupuncture (EA), as an appropriate non-pharmacotherapy supported by emerging clinical trials, the mechanism needs to be clarified. In this study, the intestinal manipulation (IM) method was used to establish the POI model, and EA was used to treat it. Sham surgery (SS), simple electrical stimulation (ES), and sham electroacupuncture (SEA) were introduced as control. Gastrointestinal transit and colonic transport were employed to evaluate interventions’ effects. RNA sequencing was then carried out using the intestine tissue of mice.

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:Inflammatory bowel disease is a chronic colonic inflammation that displays symptoms like diarrhea and weight loss. Acupuncture has been widely accepted by Western countries for the treatment of pain. In this study, we analyzed the efficacy and mechanism of electroacupuncture (EA) on trinitrobenzene sulphonic acid (TNBS)-induced colitis in mice. Mice were intrarectally administered 250 mg/kg TNBS and electroacupunctured at Quze (PC3) and Neiguan (PC6) acupoints, which have been applied for gastrointestinal disorders. Gene expression profiles in colons and spleens were analyzed by microarray for the elucidation of mechanism of EA. Our data showed that EA at PC3 and PC6 improved macroscopic and microscopic features of colitis, and the improvement displayed a frequency-dependent manner. Administration of TNBS upregulated the expression of most cytokine genes in colons, while EA downregulated the expression of TNBS-induced cytokine genes. Pathway analysis showed that EA significantly affected inflammatory pathways in colons and immunity-associated pathway in spleens. Immunohistochemical staining further showed that EA decreased the expression of interleukin-1? and nuclear factor-?B. In conclusion, this is the first study reporting the global gene expression profiles of EA on TNBS-induced colitis. Our findings suggested that inflammatory and immunity pathways were involved in the anti-inflammatory mechanism of EA on colitis induced by TNBS. In this study, we analyzed the efficacy and mechanism of electroacupuncture (EA) on trinitrobenzene sulphonic acid (TNBS)-induced colitis in mice. Mice were intrarectally administered 250 mg/kg TNBS and electroacupunctured at Quze (PC3) and Neiguan (PC6) acupoints, which have been applied for gastrointestinal disorders. Gene expression profiles in colons and spleens were analyzed by microarray for the elucidation of mechanism of EA.
