Objective To explore the effects of sliding-cup with different parameters on energy metabolism in the body by observing the effect of sliding-cup along the governor vessel on transcutaneous partial pressures of oxygen and carbon dioxide in Mìngmén(命门 GV 4) in sub-healthy people. Methods A total of 10 sub-healthy adults at rest were observed and sliding-cup along the governor vessel were conducted with three different parameters, jar-pressure of –0.01~ –0.02 MPa with sliding-cup for 5 min, jar-pressure of –0.02~ –0.03 MPa with sliding-cup for 5 min and jar-pressure of –0.02~ –0.03 MPa with slidingcup for 3 min. Peri Flux System5000 PF5040 module was employed to monitor the changes of transcutaneous partial pressures of oxygen(tcp O2) and carbon dioxide(tcp CO2) in GV 4 at 0 min, 5 min, 10 min, 15 min, 20 min, 25 min and 30 min after sliding-cup with above different interventions in sub-healthy subjects. Results After sliding-cup, tcp O2 increased at first and then decreased over time; there was no difference in tcp O2 after sliding-cupping with different parameters(all P0.05). After sliding-cup, tcp CO2 decreased; there was no difference in tcp CO2 after sliding-cup with different parameters(all P0.05). Conclusion Sliding-cup has a sustained effect on the body and can speed up the energy metabolism in the body. 展开更多

Electroacupuncture at Dazhui(GV14) and Mingmen(GV4) on the Governor Vessel has been shown to exhibit curative effects on spinal cord injury; however, the underlying mechanism remains poorly understood. In this study, we established rat models of spinal cord injury using a modified Allen's weight-drop method. Ninety-nine male Sprague-Dawley rats were randomly divided into three equal groups: sham(only laminectomy), SCI(induction of spinal cord injury at T10), and EA(induction of spinal cord injury at T10 and electroacupuncture intervention at GV14 and GV4 for 20 minutes once a day). Rats in the SCI and EA groups were further randomly divided into the following subgroups: 1-day(n = 11), 7-day(n = 11), and 14-day(n = 11). At 1, 7, and 14 days after electroacupuncture treatment, the Basso, Beattie and Bresnahan locomotor rating scale showed obvious improvement in rat hind limb locomotor function, hematoxylin-eosin staining showed that the histological change of injured spinal cord tissue was obviously alleviated, and immunohistochemistry and western blot analysis showed that Wnt1, Wnt3 a, β-catenin immunoreactivity and protein expression in the injured spinal cord tissue were greatly increased compared with the sham and SCI groups. These findings suggest that electroacupuncture at GV14 and GV4 upregulates Wnt1, Wnt3 a, and β-catenin expression in the Wnt/β-catenin signaling pathway, exhibiting neuroprotective effects against spinal cord injury. 展开更多

It masters the Yin and Yang of the body cooperating with Conception Vessel. Acupoints on Governor Vessel have been used widely in clinic. The author expounded the functional feature of Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Dazhui (GV 14) and Baihui (GV 20), which can show the characteristic of Governor Vessel and provide reference for clinical application. 展开更多

Objective:To explore the feasibility of needling the Belt Vessel(BV)for low back pain.Methods:The relevant literature was systematically reviewed;the relationship between the BV and low back pain was illustrated;the clinical features of BV-related low back pain as well as the key points of acupoint selection in treatment were summarized,and the efficacy of needling the BV for treating low back pain was observed.Results:The BV is closely related to low back pain.The main clinical manifestations of BV-related low back pain include sagging distension in the low back,enlarged abdomen,and pain radiating to the groin.The main acupoints for treating low back pain via needling the BV include Mingmen(GV4),Wushu(GB27)and Ashi points near the transverse process of the third lumbar spine.Needling the BV can swiftly and effectively relieve both the low back pain and associated symptoms.Conclusion:Needling the BV can effectively alleviate the typical BV-related low back pain. 展开更多
