Methods: Ten patients (8 women, 2 men;mean age 47.0 ±15.1 years) were enrolled. The treatment was administered over an 8-week period to 13, 4, and 9 sites on the face and head, neck, and upper back, respectively, at 5- to 15-pound intensity. The primary outcome measure was the number of days patients suffered a migraine (hereafter “number of migraine days”), and the secondary outcome measures were the six-item Headache Impact Test (HIT-6) and Visual Analog Scale (VAS) scores for migraine pain intensity and the nine-item Patient Health Questionnaire (PHQ-9) and the seven-item Generalized Anxiety Disorder (GAD-7) scale scores. Results: Nine patients completed treatment. The number of migraine days remained unchanged, from a mean 21.7 ±11.6 days/month before treatment to 19.3 ±7.3 days/month upon completion of treatment. However, the HIT-6 scores improved from 67.0 ±8.2 to 61.4 ±7.1 (p = 0.007) after 3 weeks, 61.1 ±11.5 (p = 0.01) after 6 weeks, and 59.9 ±11.6 (p = 0.035) upon completion of treatment. Similarly, the VAS scores improved significantly from 7.3 ±1.7 to 5.7 ±3.1 (p = 0.018) at 6 weeks and 4.8 ±2.8 (p = 0.011) upon completion of treatment. The GAD-7, PHQ-9, and allodynia scale scores remained unchanged. Conclusion: Our data suggest that OS is well tolerated and may become a feasible form of treatment for drug-resistant CM.展开更多

However, because of the rapid increase in food consumption, the conflicts of food quality and structure in the supply and demand equilibrium has become more and more obvious and the long-effective mechanism of food security has not been estab-lished yet. It is found that the factors affecting food security in China include the scarcity and dissipation of resources, farmers’ low enthusiasm in planting grain crops and the inappropriateness of the emphasis and measures of macro-economic regulation and control. Therefore, the authors advance to optimize resources allocation, strengthen macro-economic regulation and control and policy stimulation and establish the mechanism of allocating grain production cost, to set up the long-effective mechanism of China food security and keep it stable in the long term.展开更多

This paper investigated stimulating effect of the two insecticides on the number of laid eggs by yellow rice borer, Tryporyza incertulas(Walker) of three generations in 20012002. The results showed that the reproductive rate of emergence months during the larvae feeding on the rice plants of Xiushui63 treated with the two insecticides was significantly higher than that of control, indicating that the numbers of laid eggs by the borer was stimulated following buprofezin and imidacloprid applications. However, there was no such effect for the larvae feeding on rice variety Zhendao2 which showed moderate resistance to the insect. In addition, the incidence of stimulating egg laid for the first instar treated with the two insecticides was greater than that for the third instar. Biochemical tests showed that oxalic acid concentration declined, and photosynthetic rate of rice leaves following the two insecticide applications declined significantly compared to control, whereas reducing sugar concentration increased significantly for all other treatments of two varieties except Xiushui63 treated with buprofezin. The level of glutathione-S-transferase varied with rice variety and insecticide.展开更多
