电针足三里穴对猫食管体动力的影响

目的：观察电针健康猫足三里穴对食管体部运动的影响，研究足三里穴与食道动力调节之间的关系。方法：健康家猫28只，均行内镜检查，确定无镜下食管病（炎），随机分为足三里组、非经穴组各14只，分别应用食管测压系统测定电针双侧足三里穴与非经穴前后猫食管体部下段及上段蠕动波压力（KEPP）及传导速度。结果：电针前及电针期2组食管体部KEPP及传导速度差异均无统计学意义。电针停止后60min，足三里组食管体部下段KEPP及传导速度较电针前明显升高（88.9±23.3mmHg与75.6±19.8mmHg，3.6±1.7cm／s与1.7±0.5cm／s，均P〈0.05），非经穴组各时段均无明显改变。结论：电针健康猫足三里穴可引起食管体部下段蠕动波压力及传导速度显著增加，其机制尚未完全阐明。

Effect of Electroacupuncture at "Zusanli" (ST 36) on Esophageal Peristalsis in Cats

Objective： To observe the impact of Zusanli point （ST 36） electro-acupuncture （EA） on cats＇ esophageal motility, and to discuss the relationship between Zusanli point （ST 36） and esophageal motility regulation. Methods： After endoscopic examination, 28 cats were confirmed as healthy ones without esophagitis. All experimental cats were randomly divided into two groups： the Zusanli point （ST 36） group and the non-channels non-collaterals points group. The intraesophageal pressure and esophageal peristahic wave were recorded by applying -7-1-1-1-2-5-5-5 type 8 Channel Fine Infusion Piezometric Tube （Canada） and UPS-2020 type Esophageal Pressure Measurement System （Netherlands）. The following dynamic factors of esophagus were measured and recorded： lower esophageal peristalsis wave pressure （LEPP）, upper esophageal peristalsis wave pressure （UEPP）, peristalsis wave velocity. Results：There was no significant difference in esophageal peristalsis wave pressure and velocity between the Zusauli point （ST 36） group and the non-channels non-collaterals points group before EA. After EA, the lower esophageal peristalsis wave pressure in the Zusauli point （ST 36） group was increased from 75.64±19.81 mmHg to 88.93±23.29 mmHg （P〈0.05）, and lower esophageal peristalsis wave velocity increased from 1.71±0.46 cm/s to 3.64±1.65 cm/s （P〈0.05）. There were no statistically significant changes in upper esophageal peristalsis wave pressure and velocity after EA. In the non-channels non-collaterals points group, there were no statistically significant changes in esophageal peristaltic wave amplitude and conduction velocity. Conclusion： EA on Zusauli point （ST 36） of health cats might cause obvious increases in lower esophageal peristalsis wave pressure and velocity.
