Effect of electroacupuncture combined with aerobic exercise on IGF-I /Akt pathway in skeletal muscle of aging rats / 中国骨伤

OBJECTIVE@#To explore the effects of low-frequency electroacupuncture combined with aerobic exercise on sarocopenia, and the effects of IGF-I /Akt and its downstream signaling pathway-related protein.@*METHODS@#Naturally aging SD rats were used as research objects. Thirty-two 6-month-old male SD rats weighing 400 to 450 g were bred to 12-month-old and randomly divided into 4 groups according to body weight:Control group(YC, only grasp, fix, put back, without other intervention), electroacupuncture group (YA, electroacupuncture intervention), exercise group (YE, exercise intervention) and electroacupuncture+exercise group (YEA, electroacupuncture combined with exercise intervention). SD rats were continuously intervened from 12 months to 18 months of age. At the end of the experiment, the conditions of naturally aging rats in each group were observed:skeletal muscle wet weight / weight ratio;HE staining morphology of soleus muscle under light microscope; qPCR was used to detect the expression level of IGF-I mRNA in skeletal muscle;the expression of AKT, mTOR, p70S6K and p-p70S6K proteins in rat gastrocnemius was determined by Western blot.@*RESULTS@#In 18-month-old rats, the intervention period was 6 months. (1) Compared with YC group, YA group and YEA group significantly increased the wet weight / body weight ratio of gastrocnemius muscle in 18 months old rats. YEA group could significantly increase the wet weight / body weight ratio of soleus muscle compared with YC group YC group and YA group (@*CONCLUSION@#Electroacupuncture combined with aerobic exercise can attenuate sarocopenia in 18-month-old naturally aging rats. The molecular mechanism may be related to the promotion of protein synthesis by activating the IGF-I / Akt pathway.

Acupuncture Teratment for Lower Back Pain-Multi-center Randomized Controlled Trial using Spam Acupuncture as a Control / 全日本鍼灸学会雑誌

[Objective] We performed a multi-center randomized controlled trial using sham acupuncture as a control in the 11 institutions of Aichi and Shizuoka prefecture at which we practice our original acupuncture method. <BR>[Design · Methods] Patients were randomly allocated to four groups : A group, “Taikyoku-Ryoho” (whole body acupuncture method) pole treatment combined with low frequency electroacupuncture; B group, “TaikyokuRyoho” pole treatment; C group, low frequency electroacupuncture; D group, sham acupuncture. Therapeutic effectiveness was evaluated using a visual analogue scale (VAS) and criteria of the Japanese Orthopedic Association for low back pain (JOA score). After these evaluations, patients in B group received low frequency electroacupuncture and patients in C group received “Taikyoku-Ryoho” pole treatment. Patients in D group received both therapies. Thus, all patients eventually received the entire series of therapies. [Results] Significant improvement (P<0.05) in VAS and JOA scores was recognized after one acupuncture treatment in A, B and C groups, but not in D group. There were no differences in terms of the effectiveness among A, B and C groups.<BR>[Conclusion] Our original acupuncture method of “Taikyoku-Ryoho” combined with low frequency electroacupuncture was superior to sham acupuncture. However, the definition of sham acupuncture needs to be more clearly defined in future research.
