Methods. Forty-eight male Wistar rats were evenly randomized into control and electroaoupuncfure （EA） groups which were further divided into 5：00, 11：00, 17：00 and 23：00 subgroups respectively. EA （4- 16 Hz in the frequency, 3 V in the strength, intermittent dense-sparse waves, and duration of 20 min） was applied to bilateral “Huan- tiao” （环跳 GB 30） at 5：00 o＇clock, 11：00 o＇clock, 17：00 o＇clock and 23：00 o＇clock separately for different subgroups. After EA, the animals were killed at once for sempling the middle part of cluodenum which was fixed in 10% formalin for 2 hours, then embed in paraffin. The tissue was cut into sections （ 10 μm）, mounted on glass slides and then processed according to Grimelius＇s methods. Results： The rumber of argentaffin cells in EA group was significantly fewer than that in control group at the same timewindow （23：00, P〈0.05）. No significant differences were found between control and EA groups in the number of cells at other time window （5：00, 11：00 and 17：00 o＇clock, P〉0.05）, suggesting that EA of “Huantiao”can markedly promote the secretion activity of endocrine cells at 11：00 o＇clock during night ferent time window in a day. Conclusion. The results suggest that the effects of EA are different at clifferent time window in a day.展开更多

This paper provided a two-phase multi-warehouse and multi-task based algorithm which has two phases. In the first phase, it combines sweep algorithm, saving algorithm and virtual task point to present a method. And in the second phase it provides an algorithm for the arrangement of goods loading which is based on the constraints of time-window and attributes of goods and vehicle. It uses the computing results of the first phase to form more detailed delivery scheme based on the constraints of time-window and attributes of vehicle and goods.展开更多
