CHU Hao-ran's experience in treatment of diarrhea-predominant irritable bowel syndrome with acupuncture and moxibustion / 中国针灸

Professor CHU Hao-ran believes that the clinical diagnosis and treatment of diarrhea-predominant irritable bowel syndrome with acupuncture and moxibustion should concentrate on the integration of disease and syndrome differentiation. According to the evolution of pathogenesis, this disease is divided into 4 stages, i.e. invasion of exogenous pathogens, liver stagnation and spleen deficiency, spleen and kidney yang deficiency and interaction of cold and heat. Hence, the treatment should be provided by stages. Focusing on regulating the spleen and stomach, a specific acupuncture-moxibustion prescription is proposed, including Tianshu (ST 25), Zhongwan (CV 12), Zusanli (ST 36) and Shangjuxu (ST 37). Additionally, the combination of distal and nearby acupoints is considered and an unique needling manipulation, named the fight between dragon and tiger, is exerted. On the base of syndrome and meridian differentiation, the modern medicine is combined, stressing on the mind regulation and the mutual application of acupuncture and moxibustion in treatment. Eventually, a distinctive treatment system with acupuncture and moxibustion is formed for "regulating the spleen and stomach and differentiating meridians".

Effect of different concentrations of moxa smoke exposure on nasal mucosal injury and expression of serum IL-1, IL-6 and TNF-α in rats / 中国针灸

OBJECTIVE@#To observe the effect of long-term moxa smoke exposure of different concentrations on olfactory function in rats, and provide experimental basis of safety study of moxa smoke produced by moxibustion.@*METHODS@#Forty SD rats were randomly divided into a normal control group, a low-concentration moxa smoke group, a moderate-concentration moxa smoke group and a high-concentration moxa smoke group, 10 rats in each one. The rats in the moxa smoke groups were put into three plexiglass moxibustion boxes with different moxa smoke concentrations, 4 hours per times, twice a day for 90 days. The general state of rats was evaluated before and during the experiment. After the intervention, the olfactory function was evaluated by two-bottle experiment (TBE); the morphology of nasal mucosa was observed by HE staining; the apoptosis of olfactory epithelial cells in nasal mucosa was detected by TUNEL method; the serum levels of interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected by ELISA method.@*RESULTS@#In the late stage of moxa smoke exposure (45-90 days into intervention), the behavioral activity of rats in the moderate-concentration moxa smoke group and the high-concentration moxa smoke group was weaker than that in the normal control group, and their response to stimulation was strong, and their mental state was worse. After intervention, the drinking rate of vinegar-water mixture in the moderate-concentration moxa smoke group and the high-concentration moxa smoke group was higher than that in the normal control group and the low-concentration moxa smoke group (@*CONCLUSION@#The long-term exposure to low, moderate and high concentrations of moxa smoke could cause pathological changes in nasal mucosa and increase the serum levels of IL-1, IL-6 and TNF-α; the moderate and high concentrations of moxa smoke exposure could cause a series of damage to olfactory function and reduce olfactory sensitivity in rats.

Design and application of a moxibustion device with separated moxibustion smoke and heat / 中国针灸

In the view of the defects of the commonly used moxibustion instruments and moxa heating instruments, such as the moxa ash cannot be removed automatically, the temperature of moxibustion and moxibustion smoke is difficult to be stabilized and adjusted, and the instruments are complex and expensive, a moxibustion device with separated moxibustion smoke and heat is designed. This device can automatically remove the moxa ash and keep it on the isolation net; the temperature of the moxibustion outlet is maintained at 43-48 ℃ (effective moxibustion temperature) for more than 40 minutes, and there is no visible moxa smoke; the temperature of the moxa smoke outlet is controlled between 28-75 ℃, and the effective discharge of moxa smoke can be realized without external power equipment. This device has the advantages of stable and controllable temperature of moxibustion outlet and moxa smoke outlet, automatic removal and collection of moxa ash, separation of moxa smoke without additional power, etc., which can be used in clinical and animal experiments for moxa heating, moxa smoke removal, etc.

Effect of moxibustion on PI3K/Akt/mTOR signaling pathway in foot-pad synovium in rats with rheumatoid arthritis / 中国针灸

OBJECTIVE@#To observe the effect of moxibustion on phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin protein (PI3K/Akt/mTOR) signaling pathway in the foot-pad synovial tissue in rats with rheumatoid arthritis (RA), and to explore the mechanism of moxibustion for treating RA.@*METHODS@#Forty healthy SD rats were randomly divided into a control group, a model group, a moxibustion group, a cigarette-moxibustion group and a medication group, 8 rats in each group. The RA model was established with subcutaneous injection of complete Freund's adjuvant (CFA) in the left hind foot-pad under wind, cold and wet environment in the model group, the moxibustion group, the cigarette-moxibustion group and the medication group. The rats in the moxibustion group were treated with moxibustion at "Zusanli" (ST 36) for 20 min; the rats in the cigarette-moxibustion group were treated with moxibustion of ordinary cigarette at "Zusanli" (ST 36) for 20 min; the rats in the medication group were treated with tripterygium glycosides suspension (0.8 mg/100 g) by gavage. All the intervention was given once a day for 15 days. The left hind foot-pad volume was measured before and after modeling and after 15-day intervention. After 15-day intervention, the serum levels of IL-17 and IL-23 were detected by ELISA method, and the expression levels of PI3K, Akt and mTOR in synovial tissue of left hind foot-pad were detected by Western blot method.@*RESULTS@#The volume of left hind foot-pad, the serum levels of IL-23 and IL-17 and the expression of PI3K, Akt and mTOR in synovial tissue of left hind foot-pad in the model group were higher than those in the control group (@*CONCLUSION@#Moxibustion may play a therapeutic effect on RA by inhibiting the level of IL-23, IL-17 and the activity PI3K/Akt/mTOR, and regulating inflammatory response and autophagy.
