Abstract

Objective: To explore the underlying mechanism of electroacupuncture for anti-aging.

Methods: Forty Sprague-Dawley rats (female and male take one half for each), 3-month old, were divided into a control group, a model group, a routine electroacupuncture group (current intensity, 1 mA) and a strong electroacupuncture group (current intensity, 4.5 mA), 10 rats in each group. The model of aged rats was established by D-galactose in the latter three groups. The acupoints of "Guanyuan" (CV 4) and "Zusanli" (ST 36) were used for electroacupuncture treatment, six times per week for 4 weeks. After that, the level of interleukin 6 (IL-6) in the serum, as well as the expression of neuropeptide Y mRNA (NPY mRNA) and IL-6 receptor (IL-6R) in the periventricular hypothalamic nucleus (PVN) were examined and compared between each group.

Results: In comparison of the control rats, the model rats expressed with the lower level of NPY mRNA in PVN, higher levels of IL-6 in the serum and IL-6R in PVN, which is different from each other (P < 0.05). In both routine electroacupuncture group and strong electroacupuncture group, the level of NPY mRNA in PVN was up-regulated, in contrast, the levels of IL-6 in the serum and IL-6R in PVN were cut down, which were different from those of the model group (both P < 0.05). Furthermore, the therapeutic effect of the strong electroacupuncture group is different from that of the routine electroacupuncture group (P < 0.05).

Conclusion: Electroacupuncture at "Qiangzhuang" acupoints plays an active role to slow down the aging process on the sub-acute aged rats through regulating the function of neuro-immune system, and the therapeutic effect of strong stimulation is better than that of routine stimulation.
