ABSTRACT
Objective:To evaluate and compare electroacupunctures (EA) with different parameters and moxibustion at different temperatures influencing the activation of mast cells (MC) in Tianshu (ST 25) regions of visceral hyperalgesia model rats. Methods:Rats (except for model group) respectively accepted 1 mA or 3 mA EA or moxibustion at 43 or 4 to℃℃stimulate Tianshu (ST 25) points after randomization of the fifty visceral hyperalgesia model rats, and then were compared with that in model and normal groups. Number, degranulation numbers, degranulation rates in Tianshu (ST 25) regions MC of rats in each group were observed using toluidine blue staining. Abdominal withdrawl reflex (AWR) score was used to evaluate the rat visceral hyperalgesia reactions. Results:Compared with the normal group and the model group, MC numbers (P0.05); AWR scores in 1 mA EA group under the stimulation of 0 mmHg or 80 mmHg were significantly higher than that in the normal group (P<0.01); AWR score in 3 mA EA group under the stimulation of 0 mmHg was significantly higher than that in the normal group (P<0.01), and AWR scores in 3 mA EA group under the stimulation of 20 mmHg or 80 mmHg were also higher than that in the normal group (P<0.05). AWR scores were higher in 1 mA EA group under the stimulation of 40 mmHg or 80 mmHg than that in 4℃ moxibustion group (P<0.05); AWR score was higher in 3 mA EA group under the stimulation of 40 mmHg than that in 4℃ moxibustion group (P<0.05). Conclusion:There are differences among EA of different parameters and moxibustion of different temperatures in activating on Tianshu (ST 25) regions MC of visceral hyperalgesia model rats, as well as in improving the visceral hyperalgesia reaction. The effect of 4℃ moxibustion is the most significant.
ABSTRACT
Objective:To investigate the influence of moxibustion products on mitochondrial transmembrane potential (MTP) and mRNA expression of Bax/Bcl-2 in alveolar typeⅡ epithelial A549 cells, and to further explore influence of moxibustion products on the oxidative damage of A549 cells. Methods:Smoke and particles generated by moxibustion were collected using the filter box for gas sampling. The moxa smoke extract (MSE) was diluted sequentially to the final concentrations of 0.05 mg/mL, 0.1 mg/mL, 0.2 mg/mL, 0.3 mg/mL and 0.4 mg/mL using the cell culture medium, and A549 cells were then intervened by the above MSE solution. Cell MTP was detected by JC-1 staining. Fluorescence quantitative polymerase chain reaction (PCR) was used to detect Bax/Bcl-2 mRNA expression of A549 cells. Results: Compared with cells in the normal control group, MTP was significantly decreased in cells of 0.3 mg/mL and 0.4 mg/mL MSE intervention groups (P0.05); compared with cells in 0.05 mg/mL MSE intervention group, MTP was decreased significantly in cells of 0.1 mg/mL, 0.2 mg/mL, 0.3 mg/mL and 0.4 mg/mL MSE intervention groups (P<0.05 ); compared with cells in 0.1 mg/mL MSE intervention group, MTP was decreased significantly in cells of 0.4 mg/mL MSE intervention group (P<0.01). Bax mRNA expression of cells in each concentration of MSE intervention group all showed no significant difference compared to that in the normal control group; Bcl-2 mRNA expression of cells was reduced with the increase of MSE intervention concentration. Wherein, Bcl-2 mRNA expressions of cells in 0.4 mg/mL and 0.3 mg/mL MSE intervention groups were significantly reduced compared with that of cells in the normal control group (P<0.05); Bcl-2 mRNA expression of cells in 0.4 mg/mL MSE intervention group was significantly reduced compared to that in 0.05 mg/mL MSE intervention group (P<0.05). Conclusion:Certain higher concentration of moxa smoke could reduce MTP and mRNA expression of the anti-apoptosis gene Bcl-2 in alveolar typeⅡ epithelial A549 cells. Oxidative damage may be the important mechanism of apoptosis caused by the high concentration of moxa smoke solution, and further studies are necessary on the specific mechanisms.
ABSTRACT
BACKGROUND:The interaction and mutual influence of intestinal flora in the host intestine with mucosal immune barrier play an important role in the homeostasis regulation within the intestine. OBJECTIVE:To explore the role of intestinal flora in the pathogenesis of irritable bowel syndrome and the mechanism of moxibustion in the treatment of irritable bowel syndrome from the aspects of intestinal flora imbalance and mucosal immune activation. METHODS:With the key words of “irritable bowel syndrome, intestinal flora, intestinal immune, moxibustion” in Chinese and in English, respectively, a computer-based search was performed for articles published in CNKI, VIP and PubMed databases from October 2001 to October 2014. After the initial screening, the reserved articles were further detailed, summarized and concluded. RESULTS AND CONCLUSION:Totaly 37 articles were colected, including 15 in Chinese and 22 in English. The analysis results showed that, the imbalance of intestinal flora and mucosal immune can play an important role in the pathogenesis of irritable bowel syndrome, and the former one can affect the body’s feeling of rectal distension threshold and visceral sensitivity. Moxibustion excels at improvement of the symptoms of irritable bowel syndrome, particularly abdominal pain with high visceral sensitivity, by regulating the body’s physiological balance from multi-link and multi-target aspects.
ABSTRACT
METHODS:A computer-based online research of PubMed, CNKI and VIP databases was performed with the key words of “epigenetic; inflammatory bowel disease; Crohn’s disease; ulcerative colitis; DNA methylation; histone modification; miRNA; moxibustion” in Chinese and English. RESULTS AND CONCLUSION:The correlation of epigenetic modification with inflammatory bowel disease occurrence and development is elaborated. The mechanisms in inflammatory bowel disease have been related from DNA methylation, histone modifications and miRNA targets. The mechanism of moxibustion on inflammatory bowel disease is primarily associated with immune regulation, and its anti-inflammatory mechanism may be affected by epigenetic regulation of inflammatory cytokines.
ABSTRACT
BACKGROUND:Warm acup-moxibustion is an effective treatment in Chinese traditional medicine, which combines acupuncture with moxibustion. With an immediate analgesia or/and long-term effect, warm acup-moxibustion has been used clinicaly for acute and chronic pain. OBJECTIVE:To analyze the progress in the studies about clinical application of warm acup-moxibustion as analgesic therapy for acute and chronic pain and to discuss the influential factors. METHODS: CNKI, VIP and Wanfang databases were searched for relevant articles published between January 1995 and July 2015 using the keywords of “warm needling; warm acup-moxibustion; pain; analgesic” in Chinese. According to the exclusion and inclusion criteria, 51 articles were included in result analysis. RESULTS AND CONCLUSION: Compared with ordinary acupuncture, medicine and other treatment methods, warm acup-moxibustion can play an analgesic role in multiple systems, which is better than ordinary acupuncture and Western medicine. Warm acup-moxibustion combined with drugs and acupuncture techniques can increase the analgesic effect and improve joint function activity. Warm acup-moxibustion with the overal regulatory role plays an effective analgesic pain role in the multiple systems and shortens the duration of treatment, which is an effective method for treating pain and worthy of further promotion and application.
