Understanding acupuncture anesthesia from a foreign perspective： reviewing Acupuncture Anesthesia in the People's Republic of China. / 异域视角下对针刺麻醉的理解：以《针刺麻醉在中国》为例.

"Acupuncture Anesthesia in the People's Republic of China： A Trip Report of the American Acupuncture Anesthesia Study Group" (Report for short) is the first extraterritorial systematic investigation and evaluation report in the history of acupuncture anesthesia in China. After Report was released to the public, it has not drawn much attention in China. At the moment when acupuncture anesthesia is extended to perioperative treatment, by reviewing the Report, the differences in understanding acupuncture anesthesia were analyzed from a foreign perspective. Report involves the clinical observation of surgery under acupuncture anesthesia, the analysis on the factors of acupuncture anesthesia in therapeutic effects and the relevant mechanisms, and the differences in the research methods and foci on the recognition of acupuncture anesthesia between China and foreign countries. In association with the development of acupuncture anesthesia during the past 65 years and the conclusion in Report, the paper briefly describes the development and perfection of acupuncture anesthesia, the historical verification to the conclusions in Report and the limitations in modern acupuncture anesthesia. It provides some inspiration for the development of acupuncture anesthesia, acupuncture-moxibustion medicine and life science in the future.

[Effect of mild moxibustion at 45 ℃ with different durations at "Zusanli" （ST36） on the inflammatory factors in the abdominal aorta of hyperlipidemia rats].

OBJECTIVE: To investigate the effects of mild moxibustion at 45°C on the chronic inflammatory response of the abdominal aorta in rats with hyperlipidemia and the effects of different moxibustion durations. METHODS: Thirty-six SD rats were randomly divided into the following groups： blank control group (2 weeks), model group (2 weeks), moxibustion group (2 weeks), blank group (4 weeks), model group (4 weeks), and moxibustion group (4 weeks). A model of hyperlipidemia with chronic inflammation was established through high-fat diet feeding for 8 weeks. Rats in the moxibustion groups received mild moxibustion treatment at bilateral "Zusanli"(ST36) at 45 °C, 10 min every time, once a day, for consecutive 2 or 4 weeks. The morphology of the abdominal aorta in each group was observed by using HE staining. Contents of serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), oxidized low-density lipoprotein (ox-LDL), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), endothelin-1 (ET-1) and the contents of nitric oxide (NO), ox-LDL, and ET-1 in the abdominal aorta were measured by using ELISA. Protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta of rats in each group were detected by using Western blot and real-time fluorescence quantitative PCR respectively. The positive expression of IL-6 in the abdominal aorta of rats was detected by Immunofluorescence. RESULTS: Compared to the blank control group, rats in the model group had increased contents of LDL, TC, TG, ox-LDL, VCAM-1, ICAM-1, IL-6, TNF-α, and ET-1 in the serum, increased contents of ox-LDL and ET-1 in the abdominal aorta, increased protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta(P<0.01, P<0.05, P<0.001), with decreased HDL content in the serum, decreased NO content in the abdominal aorta (P<0.01, P<0.05), as well as dark pink abdominal aorta, rough textures in the adventitia, media, and intima, and rough endothelial layer. Compared to the model group(2 weeks), LDL, ICAM-1, ET-1 contents in the serum, ox-LDL content in the abdominal aorta were decreased(P<0.05), while serum IL-6 and TNF-α contents, and NO content in the abdominal aorta were significantly increased(P<0.01, P<0.05), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(2 weeks). Compared to the model group(4 weeks), contents of LDL, TC, TG, VCAM-1, ICAM-1, IL-6, TNF-α, ox-LDL, and ET-1 in the serum, ox-LDL and ET-1 contents in abdominal aorta, protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta were significantly decreased(P<0.05, P<0.01), while HDL content in the serum and NO content in the abdominal aorta were significantly increased(P<0.05, P<0.01), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks). In addition, content of HDL in the serum were significantly increased(P<0.05), while TNF-α content in the serum, protein expression of IL-6 in the abdominal aorta were significantly decreased (P<0.001, P<0.05), with smoother vascular walls, and clearer nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks), in comparison with the moxibustion group(2 weeks). CONCLUSION: Mild moxibustion of 45 °C at ST36 can improve vascular endothelial damage and inflammatory response induced by high-fat diet by regulating serum lipids, vascular tone, adhesion molecules, and inflammatory factors, of which the effect of moxibustion intervention for 4 weeks is more significant.
