OBJECTIVE: To evaluate the efficacy of moxibustion, through stimulating acupoints of Danzhong(CV 17) and Ganshu(BL 18) in rats with hyperplasia of mammary gland(HMG) which induced by estrogen and progestogen.METHODS: ...OBJECTIVE: To evaluate the efficacy of moxibustion, through stimulating acupoints of Danzhong(CV 17) and Ganshu(BL 18) in rats with hyperplasia of mammary gland(HMG) which induced by estrogen and progestogen.METHODS: Thirty female Sprague-Dawley rats were randomly divided into saline control group,HMG model group, and HMG moxibustion group with 10 in each group. Saline control was the group injected by saline. HMG model were created by injection of estrogen and progestogen. Moxibustion group was also injected of estrogen and progesto-gen with moxibustion at the same time. The Changes of nipple diameter and height were measured.The rats' skin temperature was recorded by an infrared thermal camera at the nipples, mammary areas,Danzhong(CV 17) and Ganshu(BL 18). Pathological changes of mammary gland in rats were also observed under light microscope.RESULTS: The diameter and height of the nipples in model group were prominently bigger and higher than that in control group(P < 0.01). The diameter and height in moxibustion group were prominently smaller and lower than that in model group(P < 0.01), and there was no significant difference between moxibustion group and control group.Compared with control group, skin temperature of the nipples, mammary area, and acupoints Danzhong(CV 17) and Ganshu(BL 18) decreased prominently in model group(P < 0.01-0.05). Compared with model group, skin temperature of that in moxibustion group increased prominently(P <0.05).CONCLUSION: Treatment with moxibustion can effectively decrease the HMG rats' nipple diameter and height, and increase the skin temperature in HMG model rats at the nipples, mammary areas,Danzhong(CV 17) and Ganshu(BL 18). This study convinces the therapeutic effect of moxibustion on mammary gland hyperplasia.展开更多

Methods： A total of 180 male Sprague-Dawley （SD） rats were randomly divided into a sham operation group, a model group, an acupoint group and a non-acupoint group, with 45 rats in each group. Rats in each group were further divided into three subgroups： postoperative 3 d, postoperative 14 d and postoperative 2l d groups, with 15 rats in each subgroup. The MCAO model was made by the modified occlusion method. The neurological function score, 2,3,5-triphenyl tetrazolium chloride （TFC） staining, immunohistochemistry assay, immunofluorescence double labeling method and Western blot were used to detect the corresponding indicators. Results： The neurological impairment of rats was most obvious at postoperative 3 d, and then gradually improved with time, which was more significant in the acupoint group （P〈0.05）. The change of infarcted volume was consistent with the neurological function impairment. The number of EphB2 positive cells （EphB2＋） around the infarcted area was decreased significantly at postoperative 3 d, and then gradually improved with time, which returned to the same level as that in the sham operation group at postoperative 21 d. The increase was most significant in the acupoint group （P〈0.05）, and the positive cell number was higher than that in the sham operation group （P〈0.01）. Western blot and immunohistochemistry results were basically consistent. Immunofluorescence displayed that EphB2＋ and postsynaptic density-95 positive （PSD-95＋） were co-expressed, after the MCAO operation, in the cortical neuron around the infracted area, and the number of co-expressing cells was increased gradually with time, which was most significant in the acupoint group （P〈0.05）. Conclusion： Electroacupuncture at Ganshu （BL 18） and Shenshu （BL 23） can significantly improve the neurological function and cerebral infarcted volume ratio of MCAO rats, which may be related to the activation of EphB2 expression in cortex around the infracted area and the promotion of synaptic remodeling.展开更多

Methods： A total of 60 cases meeting the inclusion criteria were randomized into an observation group and a control group, 30 cases in each group. Cases in the observation group received liver-regulating and blood-tonifying acupuncture, in which Jiaji （EX-B 2） points of C3_C7, Ganshu （BL 18） and Geshu （BL 17） were used; cases in the control group received routine acupuncture treatment in which jiaji （EX-B2） points of C3.C7 were used. Both groups received 5 times of treatment in a week with a 2-day rest, symptoms evaluation was done after 4 weeks of treatment, and then therapeutical effect was evaluated. Results： The total effective rate was 90.0% in the observation group, 73.3% in the control group, and inter-group comparison showed a statistical significance （P〈0.05）. After treatment, the symptoms and signs scores in both groups all substantially dropped, showing statistical significances （both P〈0.05）; inter-group comparison showed that the improvements in subscales of dizziness, pressing pain along vertebrae and revolve-cervix test in the observation group were superior than those in the control group, showing statistical significances （all P〈0.05）, while the inter-group comparisons of subscales of headache and vomiting and nause didn＇t show any statistical significances after treatment （both P〉0.05）. Conclusion： Liver-regulating and blood-tonifying acupuncture is effective in treating cervical spondylosis of vertebral artery type, and it can significantly improve patients＇ symptoms and signs.展开更多

Methods： A total of 180 healthy male Sprague-Dawley （SD） rats were randomly divided into a sham operation group, a model group, an acupoint group and a non-acupoint group, 45 rats in each group. MCAO model was established using the modified line-embolus method in all rats except for those in the sham operation group; rats in the acupoint group were treated with EA at Ganshu （BL 18） and Shenshu （BL 23）; rats in the non-acupoint group were treated with EA at the control points; rats in other 2 groups were only subjected to bundling without treatment. Ten rats in each group were randomly selected on the 3rd day, the 14th day and the 21st day after acupuncture stimulation to test the neurological function impairment. The expression levels of CD31 and VEGF were also detected. Results： Compared with the model group and non-acupoint group, the neurological function score of the acupoint group was decreased at each time point, and the differences were statistically significant （P〈0.05, P〈0.01）. The expressions of VEGF and CD31 in each group were the lowest on the 3rd day, reached the peak on the 14th day and still remained at high level on the 21st day. And the differences among groups were statistically significant both on the 14th day and the 21st day （P〈0.05, P〈0.01）. Compared with the model group and the non-acupoint group, the expressions of VEGF and CD31 in the acupoint group were increased, and the differences were statistically significant （all P〈0.05）. Conclusion： EA at Ganshu （BL 18） and Shenshu （BL 23） can significantly improve the neurological function score of MCAO model rats, and shows protective effect on cerebral ischemia. The protective mechanism may be related to the up-regulation of CD31 and VEGF expression around the cerebral infarction focus in the MCAO model rats and induction of angiogenesis.展开更多
