    Objective: To observe the effect of electroacupuncture (EA) on the expression of NF-κB p65 in hippocampus and the morphology of hippocampus in rats with chronic fatigue syndrome (CFS), so as to explore its mechanism in improving cognitive dysfunction of CFS.

    Methods: Forty-eight SD rats were randomly divided into control, model, EA and inhibitor groups (n=12 in each group). The CFS model was established by multi-factor compound stress stimulation method. Rats of the EA group received EA (50 Hz, 1 mA) at "Baihui" (GV20), Emotional Area I and bilateral Sensory Area for 30 min, once daily for 15 days. For rats in the inhibitor group, pyrrolidine dithiocarbamate (100 mg·kg-1·d-1) was injected intraperitoneally, once a day for 15 days. Learning and memory ability was evaluated by Morris water maze test. HE staining was used to observe the morphology of hippocampus. Western blot was used to determine the expression level of NF-κB p65 in hippocampus.

    Results: After mode-ling, the general status score was increased (P<0.01), the escape latency was prolonged(P<0.01), the times of crossing the platform was decreased(P<0.01), and the expression level of NF-κB p65 in hippocampus tissue was significantly increased (P<0.05) in the model group compared with the control group. Compared with the model group, the general status score was decreased (P<0.01), the escape latency was shortened(P<0.01), the times of crossing the platform was increased(P<0.01), and the expression level of NF-κB p65 in hippocampus tissue was significantly decreased (P<0.05) in the EA and inhibitor groups. HE staining showed that in the model group, the hippocampal nerve cells were arranged disorderly, the structure was loose, and the number of apoptotic bodies and inflammatory cells was significantly increased. The degree of tissue damage of the EA and inhibitor groups was milder than that of the model group.

    Conclusion: EA can improve the cognitive function in CFS rats, which may be associated with its effect in inhibiting the expression of NF-κB and reducing the inflammation response in hippocampus.

    No need to read beyond that.

    We can't even clinically verify ME in humans, and going by questioning humans (who can communicate in words) is fraught with difficulties, so any claims for rats with ME seems kind of meaningless.

    This is annoying on so many levels. I started out feeling dreadfully sorry for the rats, who were put through this for no good reason. I ended up also feeling dreadfully sorry for all the people with ME/CFS who are now going to have well-meaning relatives encouraging them to try this 'cure'.

    I wish I hadn't clicked on this. Maybe one day in the future human beings will look back on such gratuitous, pointless, barbaric practises with horror. That's if we make it. Maybe the rats will have the last laugh.
