Effects of Shuanggu Yitong needling method on proliferation and differentiation of nerve stem cells in the Parkinson's disease model rat / 中国针灸

<p><b>OBJECTIVE</b>To explore the mechanism of acupuncture in treatment of Parkinson's disease.</p><p><b>METHODS</b>Fifty Wistar rats were randomly divided into a normal control group, a sham-operation control group, a model group, a Fengfu-Taichong group and a Shuanggu Yitong group. The hemilateral rotation Parkinson's disease model was prepared by micro-injection of 6-hydroxyl-dopamine into the right striatum. Effects of acupuncture at "Fengfu" (GV 16), "Taichong" (LR 3) hy Shoanggu Yitong needling method on proliferation and differentiation of nerve stem cells in the Parkinson's disease model rat were compared. Proliferation and numher changes of the nerve stem cells in the suhstantia nigra and the striatum were investigated with immunohistochemical method, and the number of nerve stem cells transforming neurons were observed with immunohistochemical double-labeling method.</p><p><b>RESULTS</b>In the two acupuncture groups, the proliferative cells in the substantia nigra and thestriatum of the destroyed side increased significantly (P < 0.01), and the number of nerve stem cells and the number of transformed neurons in the destroyed side of the substantia nigra and the striatum increased significantly only in the Shuanggu Yitong group (P < 0.01).</p><p><b>CONCLUSION</b>Shuanggu Yitong needling method can induce proliferation and differentiation of nerve stem cells in the substantia nigra and the striatum regions in the Parkinson's disease model rat.</p>

Effect of "Shuanggu Yitong" acupuncture therapy on interleukin-6 of experimental rats with postmenopausal osteoporosis / 中华中医药杂志

Objective:To study the mechanisms that acupuncture therapy of "Shuanggu Yitong" in treating postmenopausal osteoporosis(PMO).Methods:60female SD rats aged 6 months were resected bilateral ovaries and feeded for 90 days in order to make the model of experimental osteoporosis.Then,they were divided into 5 groups such as control group,regular acupoints treated group,"Shuanggu" group,"Yitong" group,"Shuanggu Yitong" group,with 12 rats each group,and the control group without any treatment;Pishu(BL 20),Weishu(BL 21),Shenshu(BL 23),Qihaishu(BL 24) was selected for the regular acupoints treated group;Guanyuan(RN 4),Zusanli(ST 36) for the "Shuanggu" group;and Shenshu(BL 23),Geshu(BL 17),Dazhu(BL 11) for the "Yitong" group;Guanyuan(RN 4),Zusanli(ST 36),Shenshu(BL 23),Geshu(BL 17),Dazhu(BL 11)for the "Shuanggu Yitong" group.Electroacupuncture therapy was given once a day,15 minutes each time,the needles were retained for 10 minutes.Then these rats rested for 1 day after consecutive therapy for 6 days.The therapy lasted for 12 weeks.RT-PCR was used to examine the expression level of interleukin-6(IL-6)mRNA in bone tissue.Results:Compared with control group,the expression level of IL-6mRNA in all acupuncture therapy groups decreased(P0.05).Conclusion:Acupuncture can reduce the expression level of IL-6mRNA in osteoporosis model rats without ovaries and "Shuanggu Yitong" acupuncture therapy is superior to other regular acupuncture therapy.
