The model rat s of adjuvant arthritis were prepared by intradermal injection of 0.1 mL of Freund’s adjuvant complete into the metatarsal of the right posterior foot to induce inflammation.No intervention was given in Group CFA, while electroacupuncture was performed in the other three groups at 'Zúsānlǐ(足三里 ST 36, bilaterally)' and 'Huántiào(环跳 GB 30, bilaterally)' of the rats with the following electroacupuncture parameters: dilatational wave with a frequency of 2/10 Hz, an intensity of 5/10/15(0.76/1.53/2.3 mA), a duration of 30 min, and an intensity increasing every 10 min. In Group DMSO + EA, DMSO(with a concentration of 0.2%, 50μL/acupoint) was injected at bilateral 'ST 36' of the model rats one hour before electroacupuncture, while GW4869(with a concentration of 3 mg/mL,50μL/acupoint) was injected at bilateral ST 36 of the model rats one hour before electroacupuncture in Group GW4869 + EA. The paw withdrawal latency(PWL) was used as the therapeutic effect index.Results: The PWL of rats in each group at Hour 24 after modeling was significantly lower than that before modeling, indicating that the models were successfully established. After the electroacupuncture treatment, the PWL of rats showed an increasing trend in all groups. The PWL of Group GW4869 + EA(6.74 ±1.09)s was lower than that of Group EA(7.72 ±1.54)s on Day 1 after injection, but the difference was not statistically significant(P> 0.05). The PWL values of Group GW4869 + EA(7.72 ±0.70)s,(7.87 ± 0.58)s were significantly lower than those of Group EA(9.96 士 0.94)s,(9.66 ±0.96)s(both P< 0.05)on Days 2 and 3 after injection, and the differences were statistically significant.Conclusion: It was preliminarily found that acupuncture analgesic effect was significantly reduced after local exosomes of acupoints were blocked, indicating that local exosomes of acupoints may be involved in the initiation process of acupuncture effect.展开更多

Using prefecture city-level panel data covering China ＂s 262 prefecture cities for the period 2004-2013 and employing a dynamic panel system generalized method of moments model with instrumental variable regression techniques, our study finds that FDI and exports have, on average, played a significantly positive role in China＇s urbanization. However, the impacts of FDl and exports on urbanization vary across regions. FDI has a positive and significant impact on urbanization in the coastal region but has no impact on urbanization in the inland region. Exports have a positive and significant impact on urbanization in both the coastal and inland regions, but the effect is much larger in the coastal region than in the inland region. The results imply that further attracting FDI inflows and promoting exports will contribute to China＇s urbanization, especially for the inland region.展开更多
