功能性肠病患者敏化穴位的分布

Distribution of Sensitized Acupoints on Patients with Functional Intestinal Disorder

目的:临床验证穴位在疾病状态下是否存在痛觉敏化及穴位面积的改变。方法:采用电子Von Fray测定了正常人、功能性肠病患者与胃肠疾病相关的13个穴位及其周围1寸、2寸、同神经节段的参照点的压痛阈值,并和穴位异神经节段的参照点做比较,求得其穴位的相对压痛阈值,和正常健康志愿者的相对压痛阈值进行比较,分析功能性肠病患者体表相关敏化穴位的分布和痛敏感度变化。结果:功能性肠病患者的足三里、上巨虚、下巨虚穴的压痛阈值显著下降(P<0.05),其旁开1寸和2寸及其同神经节段非穴位点的压痛阈值较正常对照组显著下降(P<0.05),阴陵泉穴位及其旁开1寸的压痛阈值与对照组比较有显著下降(P<0.05)。功能性肠病便秘患者在疾病状态下,曲池及其同神经节的压痛阈值、大肠俞的压痛阈值与正常对照组比较显著下降(P<0.05),处于痛敏感状态。结论:功能性肠病患者会出现某些穴位的痛敏和痛敏的范围增大,说明穴位处于敏化状态。敏化的穴位不只是一个点,而是一个相对敏感的功能区域,其在病理状态下反应更加敏感,反映疾病的功能增强。

Objective： To observe the hyperalgesia of acupoints due to functional intestine disorder and detect the area of sensitized acu- points. Methods：We measured the pressure pain threshold （PPT） by electronic yon fray. PPT was detected and compared among pa- tients of functional intestine disorders and normal control on 13 acupoint related to intestinal disorders, l cun, 2cun beside the acupi- oints, the control point in hemosegement and heterosegement. Results： 1 ） the PPTs of acupoints ST 36, ST 37, ST 39, SP9; leun, 2eun beside the acupioints, the control point in hemosegement in patients decreased significantly compared with the control group （P 〈 0. 05 ） ; 2） the PPTs of acupoints LII 1 and BL25 in patients of functional constipation decreased significantly compared with the control group （P 〈 0. 05 ）. Conclusion：The results indicated that acupoints were not settled in a fixed point but in a certain area. Some acupoints could be sensitized as well as the sensitive area of acupoints were widen during pathological process.
