Methods Multi-center （3 First-Class hospitals） study was adopted, and the involved 3 hospitals did clinical observation according to the requirements of the project. The methods are as follows. All cases were randomized into treatment group and control group according to their sequence. QIǖXǖ（丘墟GB40） was selected in treatment group, while Tiānshū （天枢 ST25） was selected in control group. Both groups were performed electro acupuncture, and syndromes indexes of migraine and 5-HT were observed before and after treatment. All data were analyzed by statistic software SPSS11.5. Results There was significant difference of VAS margin between two groups in each center and the combined center （u= -3. 362, P=0. 001 ）. There was significant difference of therapeutic effect of 4-week treatment between two groups in each clinical center and the combined center. The therapeutic effect of 3-month treatment between two groups in No. 1 and No. 3 hospitals, showed significant difference, the treatment group was better; while that of No. 2 hospital had no obvious difference. The therapeutic effect of 6-month treatment between two groups in each center and the combined center had significant difference, the treatment group was better. Conclusion The therapy of electro acupuncture at QIǖXǖ（丘墟GB40） is effective for migraine.展开更多

To represent the dynamic and nonlinear behavior of the process, the ARX combined with neural network is used in the partial least squares (PLS) inner model between input and output latent variables. In the proposed dynamic optimization strategy based on the ARX-NNPLS model, neither parameterization nor iterative solving process for DAEs is needed as the ARX-NNPLS model gives a proper representation for the dynamic behavior of the process, and the computing time is greatly reduced compared to conventional control vector parameterization method. To demonstrate the ARX-NNPLS model based optimization strategy, the polyethylene grade transition in gas phase fluidized-bed reactor is taken into account. The optimization results show that the final optimal trajectory of quality index determined by the new approach moves faster to the target values and the computing time is much less.展开更多

In addition, the y also introduce its operation methods and some points for attention. During ope ration of the elongated needle, the operator should manipulate it gently, avoidi ng rude insertion and rash withdrawal; rather, utilize the elasticity of the steel wire to press the needle downward slowly, and cause the favorable needlin g sensations to spread slowly downward to the affected region along with the mov ement of the needle body.展开更多

Methods:Thirty-six patients with post-stroke spastic hemiplegia were randomly divided into a treatment group and a control group, 18 cases in each group. The two groups were all given rehabilitation training. The contralateral needling was adopted in the treatment group on the acupoints group of brain-refreshing and orifice-opening needling method. The routine acupuncture was applied in the control group on the same acupoints. Respectively before and after the treatment, the modified Ashworth scale (MAS) and clinical spasticity index (CSI) were used to assess the therapeutic effects. Results:The total effective rate was 94.4% in the treatment group and 67.7% in the control group, with a statistical difference in comparison of the two groups (P<0.05). In comparison of MAS and CSI scores after the treatment between the treatment group and control group, the differences were statistically significant (P<0.05). Conclusion:The contralateral needling plus rehabilitation training is an effective method for the treatment of post-stroke spastic hemiplegia.展开更多
