Anti-aging effects of moxa cone moxibustion As a free radical scavenger complement

Therapies that complement free radical scavenging are an important approach for treating aging in the brain. In the present study, two formulations of moxa cone moxibustion were applied at acupoints Zusanfi （ST 36） and Xuanzhong （GB 39）, and at acupoints Baihui （DU 20） and Guanyuan （RN 4）, in D-galactose-induced senile mice. The results revealed that moxa cone moxibustion improved total superoxide dismutase and Cu/Zn-superoxide dismutase activity in the homogenates of the cerebral tissue, as well as ameliorating deficits in neuronal morphology and neuronal density in the cerebral cortex and hippocampal CA3. Moxa cone moxibustion also enhanced learning and memory functions of senile mice. Moxa cone moxibustion at Zusanli, Xuanzhong, Baihuiand Guanyuan acupoints can thus be used to complement free radical scavengers, with efficacy that is equal to that of electroacupuncture at Zusanliand Xuanzhong, and superior to that of nimodipine treatment.

Methods： Sixty cases in conformity with the inclusion criteria were divided into two groups randomly. Thirty cases in the treatment group were treated by moxa cone moxibustion on Pishu （BL 20） and Shenshu （BL 23）, while 30 cases in the control group were treated by oral administration of herbal medicine. The therapeutic effects were compared after one treatment course. Results： The total effective rate was higher in the treatment group than that in the control group, and the difference between the two groups was statistically significant （P0.05）. Conclusion： Moxa cone moxibustion is better than oral administration of herbal medicine in treatment of chronic intractable diarrhea.

Comparative Study on the Analgesic Effects of Different Moxibustion Methods with Tai-yi Moxa Stick in Treating Primary Dysmenorrhea

Objective: To compare the therapeutic effects of two different moxibustion methods both with tai-yi moxa stick in treating primary dysmenorrhea. Methods: Forty-three patients were randomized into two groups by the random number table according to their treatment orders. The causalgic group was intervened by causalgic stimulation with tai-yi moxa stick while the tepid group was treated by mild thermal stimulation with tai-yi moxa stick. Shiqizhui(EX-B 8) was selected for both groups. Visual analogue scale(VAS) was used for observation before and during the treatment by every 10 min to compare the clinical efficacies between the two groups. Results: Before treatment, there was no statistically significant difference in pain intensity between the two groups(P>0.05). After treatment, both groups achieved significant improvements in pain intensity(P < 0.05), but the inter-group difference in pain intensity was still statistically insignificant(P > 0.05), but the difference was enlarged comparing with that before treatment. The pain relief during the first 10 min of treatment was slower in the causalgic group than that in the tepid group. However, during the later 20 min, the pain relief in the calsalgia group gradually outpaced that in the tepid group. Conclusion: The two moxibustion methods with tai-yi moxa stick both have a good instant analgesic effect in treating primary dysmenorrhea. For patients with primary dysmenorrhea, if 30 min is regarded as the treatment time, mild stimulation was suggested to be used for the first 10 min, and causalgic stimulation for the later 20 min to achieve a better curative effect.

Effects of moxibustion at different times on prostaglandin and vasopressin levels in uterine tissues of rats with dysmenorrhea due to cold-dampness retention

Objective： To observe the effects of moxibustion at different times on prostaglandin E_2（PGE_2）, prostaglandin F2α（PGF_（2α））and arginine vasopressin（AVP）, in the uterine tissues of rats with dysmenorrhea due to cold-dampness retention, and to explore the differences and possible mechanisms of moxibustion at different times in easing pain in dysmenorrhea due to cold-dampness retention.Methods： Forty-three female Wistar rats were randomly divided into a blank control group（n=7）, a model group（n=9）,a pre-moxibustion group（n=9）, an immediate-moxibustion group（n=9） and a pre-moxibustion plus immediatemoxibustion group（n=9）. Rat models of primary dysmenorrhea due to cold-dampness retention were established using（0±1） ℃ ice water immersion method combined with injection of estradiol benzoate for 10 d, followed by injection of oxytocin on the 11 th day. Rats in the 3 intervention groups received moxibustion to Shenque（CV 8） and Guanyuan（CV 4）, 10 min for each acupoint, once a day. Rats in pre-moxibustion group were given mild moxibustion, beginning on the 8th day during modeling, for 3 continuous days; rats in immediate-moxibustion group were given one time mild moxibustion, immediately after injection of oxytocin on the 11 th day during modeling; rats in pre-moxibustion plus immediate-moxibustion group were given mild moxibustion, beginning on the 8th day during modeling till immediately after injection of oxytocin on the 11 th day during modeling, for 4 continuous days. The level of PGF_（2α） in the rat uterine tissues was measured by enzyme-linked immunosorbent assay（ELISA）, and the levels of PGE_2 and AVP in rat uterine tissues were measured by radioimmunoassay.Results： Compared with the blank control group, the levels of PGF_（2α） and AVP, the PGF_（2α）/PGE_2 ratio in the model group were significantly increased（P〈0.01）, and the PGE_2 level was significantly decreased（P〈0.01） in the rat uterine tissues in the model group. Compared with the model group, the writhing latency was significantly prolonged, the writhing number and the total writhing score were all decreased in the pre-moxibustion group, the immediate-moxibustion group and the pre-moxibustion plus immediate-moxibustion group（all P〈0.01）; the levels of PGF_（2α） and AVP, and the PGF_（2α）/PGE_2 ratio were all significantly decreased（P〈0.05, P〈0.01）, and the PGE_2 level was significantly increased（P〈0.01） in the rat uterine tissues of the 3 treatment groups. Compared with the pre-moxibustion group, the writhing number and the total writhing score were all decreased in the immediate-moxibustion group and the pre-moxibustion plus immediate-moxibustion group（all P〈0.01）, the writhing latency was significantly prolonged in the pre-moxibustion plus immediate-moxibustion group（P〈0.01）; the levels of PGF_（2α） and PGF_（2α）/PGE_2 ratio were significantly decreased（P〈0.05, P〈0.01）, and the PGE_2 level was significantly increased（P〈0.01） in rat uterine tissues in the immediate-moxibustion group and the pre-moxibustion plus immediate-moxibustion group. Compared with the immediate-moxibustion group, the writhing latency was significantly prolonged and the writhing number wasdecreased（all P〈0.05）, and the total writhing score was decreased（P〈0.01） in the pre-moxibustion plus immediatemoxibustion group; the PGF_（2α） level and the PGF_（2α）/PGE_2 ratio were significantly decreased（P〈0.01）, and the PGE_2 level was significantly increased（P〈0.01） in rat uterine tissues in the pre-moxibustion plus immediate-moxibustion group.Conclusion： Moxibustion at different times all can produce obvious analgesic effects on dysmenorrhea due to cold-dampness retention in rats, and pre-moxibustion plus immediate-moxibustion ranks the top. The mechanism of this analgesic effect may be via the regulation of abnormal PGF_（2α）, PGE_2 and AVP levels, to effectively inhibit the spastic contraction of uterine smooth muscle in dysmenorrhea rat, thereby improving the ischemia and hypoxia in uterus.

Objective:To observe the clinical efficacy of heat-sensitive moxibustion plus medications on senile osteoporosis(SOP),and to explore the related mechanisms.Methods:A total of 70 elderly participants with osteoporosis were randomly divided into an observation group and control group,with 35 cases in each group.The control group was treated with conventional drugs,and the observation group was treated with heat-sensitive moxibustion on the basis of the conventional drugs.Both groups were treated for 3 months.Before and after treatment,assessed the visual analog scale(VAS)and Oswestry disability index(ODI)scores,determined the bone mineral density of the participants'lumbar spine(L2-L4)and left femoral neck,and detected the participants'serum bone morphogenetic protein-2(BMP-2)and osteoprotegerin(OPG)levels.Results:After treatment,the VAS scores of both groups were lower than before treatment(both P<0.05),and the VAS score of the observation group was significantly lower than that of the control group(P<0.05).After treatment,the bone mineral density values of the lumbar spine and left femoral neck in both groups were significantly higher than before treatment(both P<0.05),and the bone mineral density values of the observation group were higher than those of the control group(P<0.05).After treatment,the ODI scores of the two groups were lower than those before treatment(both P<0.05),and the ODI score of the observation group was lower than that of the control group(P<0.05).After treatment,the serum BMP-2 and OPG levels in the observation group were significantly higher than those in the control group(both P<0.05).Conclusion:Heat-sensitive moxibustion plus medications for SOP can significantly relieve patients'pain,improve dysfunction,and increase bone density,which may be related to the improvement of the serum BMP-2 and OPG levels.

Experimental study on the effect of different moxibustion durations on rats with rheumatoid arthritis

Objective： To observe the effect of different moxibustion durations on rats with rheumatoid arthritis（RA） and to evaluate the relationship between moxibustion amount and moxibustion efficacy. Methods： Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley（SD） rats, and the other 32 rats were used to establish type Ⅱ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu（BL 23） and Zusanli（ST 36） for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin（IL）-1β and tumor necrosis factor（TNF）-α, arthritis index（AI） scores, toe volumes and pathological score of synovitis were evaluated in the rats. Results： Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant（P〈0.01）, before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index（AI） scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group（P〈0.05 or P〈0.01）. Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant（P〈0.05 or P〈0.01）. There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group（all P〈0.05）. The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group. Conclusion： The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

Objective： A questionnaire for the compliance with moxibustion was designed based on the 4-item Morisky scale, and the reliability and validity of the questionnaire was investigated. Methods： A modified Morisky scale was designed based on the 4-item Morisky scale for the compliance with moxibustion, and 146 patients having received moxibustion for over 2 weeks were investigated using this scale to evaluate their compliance with moxibustion; the internal equity and the construct validity of the scale were statistically analyzed. Results： The analysis of reliability showed that in item of internal consistency, the Cronbach＇s α was 0.72 and the split-half coefficient was 0.71, the correlation coefficients between the 4 component scores and the total score ranged 0.67-0.80, and the between-component correlation coefficients ranged 0.24-0.56; the exploratory factor analysis（EFA） totally extracted 1 common factor, and the explicable variation was 55.02%, and the loads of the 4 items were respectively 0.82, 0.81, 0.74 and 0.58. Conclusion： The reliability and validity of the modified Morisky scale for the compliance with moxibustion are acceptable, while several items need further modification and improvement in the expression and content.

Observation on Clinical Effects of Moxibustion Therapy plus Medications for Chronic Heart Failure

Objective： To observe the clinical effects in treatment of chronic heart failure with mild moxibustion plus medications. Methods： Sixty cases with chronic heart failure who met the inclusion criteria were randomly divided into two groups, 30 cases in each group. The treatment group was treated with mild moxibustion plus routine medications and the control group was treated only with routine medications, for comparing the clinical effects and relevant indexes of heart functions between the two groups after the treatment. Results： The heart rate （HR）, cardiac output （CO） and left ventricular ejection fraction （LVEF） were obviously improved in the two groups after the treatment （P0.01）, better in the treatment group than those in the control group （P0.01）. The total effective rate was better in the treatment group than that in the control group （P0.05）, indicating that both therapeutic programs were effective for chronic heart failure, but the clinical effect was better in the treatment group. Conclusion： The clinical effect is better in the treatment of chronic heart failure by mild moxibustion plus medications than by single application of medications.

Effect of mild-warm moxibustion on fatigue, immunestate and quality of life in sub-health population

Objective： To observe the effect of mild-warm moxa stick moxibustion on fatigue, immune state and quality of life （QOL） in sub-health population. Methods： A total of 120 cases were randomly allocated into a moxibustion group （n=60） and a Chinese patent medicine （CPM） group （n=60）. People in the moxibustion group were intervened with mild-warm moxa stick moxibustion, once a day; while people in the control group took oral Bu Zhong Yi Qi Won （Spleen/stomach-supplementing and Qi-boosting Pill）, 3 doses a day. Two months made up a course of treatment. The fatigue, immune state and QOL were then observed after one treatment course, followed by a 12-month follow-up. Results： A total of 215 cases completed the clinical trial. After intervention, the fatigue scores, immune parameters and QOL scores were significantly increased in both groups, showing statistical significances （P〈0.05）. There were between-group significant differences in fatigue score, levels of immunoglobulin M （IgM） and IgG, natural killer （NK） cell activity and QOL score （P〈O.05）. After the 22-month follow-up, there were still significant between-group differences in fatigue score, physical health, psychological, social relationships and overall perception of QOL and overall perception of health （P〈0.05）. Conclusion： Mild-warm moxibustion can markedly improve the fatigue, immune state and QOL in sub-health population.
