https://www.selleckchem.com/Bcl-2.html The implementation of acupuncture and moxibustion refers to acupuncture or moxa burning at the selected sites on the surface of the body, and such sites have different natures and belong to different categories. The current theoretical system of acupuncture and moxibustion only contains the category of "acupoints" and their classification and does not cover all related concepts, which has an adverse effect on the inheritance, application, and research of acupuncture and moxibustion. Based on a deeper analysis of related theories, this article analyzes the nature and features of different sites for acupuncture and moxibustion on the surface of the body and proposes a frame for the classification of acupuncture treatment sites, hoping to constantly improve the theoretical system of acupuncture and moxibustion and give full play to its role. To investigate the clinical effect and safety of moxibustion therapy based on Sancai theory for reinforcing intelligence in the early intervention of mild cognitive impairment (MCI). A total of 210 patients with MCI were divided into moxibustion group and medication group using a random number table, with 105 patients in each group. The patients in the moxibustion group were given moxibustion at Baihui (GV20), Shenque (CV8), and Yongquan (KI1) once every other day, 20 minutes each time, for a total of 8 weeks, and those in the medication group were given oral Nimodipine 30 mg once a day for 8 weeks. Mini-Mental State Examination (MMSE) score, score of meaningless graphics recognition of Clinical Memory Scale (CMS), and event-related potential P300 latency were evaluated before treatment, after 8 weeks of treatment, and at 12 weeks after treatment, and the safety of treatment was analyzed for both groups. Both groups had significant increases in MMSE score and the score of meaningless graphics recognition of CMS and a significant reduction in P300 latency after treatment and during follow-up (
