Alter intragastric administration of Ecr to rats, the effect of Ecr on the changes of gastric motility was detected. At the same time, the changes of frequency of electro-physiological activity, as well as expression of c-Fos in nucleus tractus solitari and dorsal-nuclei of the central bulb were also observed. The mechanism of Ecr on gastric motility were also detected by observing the activation of the NTS and DMV.

Results: The distribution of NADPH-d products and Fos positive neurons was partly overlapped in the PBN. The NADPH-d positive neurons adjoined the Fos positive neurons in the dorsal lateral subnuclear and some Fos/NADPH-d double labeled neurons were observed. The Fos positive neurons were intermingled with the NADPH-d positive fiber terminals in the external lateral subnuclear.

结果：PBN内Fos阳性神经元与NADPH-d阳性产物的分布范围部分重叠：在臂旁外侧核背亚核内，Fos阳性神经元与NADPH-d阳性神经元相互邻接，并可见部分Fos/NADPH-d双标神经元；在臂旁外侧核外亚核内，Fos阳性神经元与NADPH-d阳性纤维终末相互混杂分布。

Fruit oblong-ovoid, base cordate, flattened dorsally; surface covered with many convex and shining dots; dorsal ribs prominent, the lateral broadly thin-winged; vittae 1–3 in each furrow, 2–8 on commissure; mesocarp thin, hollow in mature fruit.

长圆状卵球形的果，基部心形，背面扁平；为很多凸并且发亮的小圆点所覆盖的表面；突出的背棱，薄翅的宽侧；油管1-3在每棱槽，2-8在合生面上。

Methods All 380 patients with cerebral palsy, admitted from January 2003 to March 2008, were studied retrospectively. Based on the position of spasticity, selective peripheral denervation was performed, including spinal dorsal root of lumbosacral region, sciatic nerve, obturator nerve, peroneal nerve.

回顾2003年1月至2008年3月收治的380例脑瘫患者，根据痉挛部位不同，选择相应周围神经进行部分切断，包括：腰骶段脊神经后根、坐骨神经、闭孔神经和胫神经。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。
