In the present study, two formulations of moxa cone moxibustion were applied at acupoints Zusanfi （ST 36） and Xuanzhong （GB 39）, and at acupoints Baihui （DU 20） and Guanyuan （RN 4）, in D-galactose-induced senile mice. The results revealed that moxa cone moxibustion improved total superoxide dismutase and Cu/Zn-superoxide dismutase activity in the homogenates of the cerebral tissue, as well as ameliorating deficits in neuronal morphology and neuronal density in the cerebral cortex and hippocampal CA3. Moxa cone moxibustion also enhanced learning and memory functions of senile mice. Moxa cone moxibustion at Zusanli, Xuanzhong, Baihuiand Guanyuan acupoints can thus be used to complement free radical scavengers, with efficacy that is equal to that of electroacupuncture at Zusanliand Xuanzhong, and superior to that of nimodipine treatment.展开更多

Methods： Tuina therapy was applied on 37 cases of postoperative urinary retention; Qihai （CV 6）, Guanyuan （CV 4）, Zhongji （CV 3） and bilateral Sanyinjiao （SP 6） were selected. Results： Thirty-six cases were cured and 1 case was not surveyed after 1 to 3 treatments. Conclusion： Point tuina is an effective method in treating postoperative urinary retention.展开更多
