目的:探讨肝区经穴反映病症的生物医学基础。阐明经穴效应局部特异性对肝区血流变化与穴位下组织形态改变的影响及相关临床意义。方法:采用彩色超声多普勒技术和定点低频超声方法对比172例不同健康状态患者的步廊穴对应的肝脏解剖组织结构检出率以及门静脉主干血管内径(DPV)、平均血流速度(VPV),计算门静脉充血指数(CI)。依据不同健康状态进行资料分组。统计分析步廊穴下组织形态改变与血液动力学数据变化的相关性。结果:慢乙肝组DPV与CI均高于肺结核患者(P<0.05);疾病组步廊穴下门静脉系统分支比例高于健康对照组(P<0.05);肝硬化组门静脉高压患者步廊穴下检出门静脉矢状部比率较其他组升高(P<0.05)。结论:肝脏疾病状态中穴位深层解剖结构变异是步廊穴敏化的关键因素之一。
Objective: To investigate the biomedical basis of acupoints reflecting the disease in the liver area. To clarify the local specificity of acupoints effect on changes of hepatic blood flow and acupoint tissue morphology changes and related clinical significance. Methods: The detection rates of liver anatomical structure, the diameter of the main portal vein (DPV) and the mean velocity of blood flow (VPV) in 172 patients with different health status were compared by color Doppler ultrasound and fixed-point low- , Calculated portal vein congestion index (CI). According to different health status data grouping. Statistical Analysis of Correlation between Change of Acupoint Organization and Changes of Hemodynamic Data in Stepped Corridor. Results: The DPV and CI of chronic hepatitis B group were significantly higher than those of pulmonary tuberculosis patients (P <0.05). The proportion of portal vein branches in the pathological group was significantly higher than that of the healthy control group (P <0.05) The rate of portal vein sagittal detection was higher than other groups (P <0.05). Conclusion: The variation of deep anatomic structure of the acupoints in the liver is one of the key factors of sensation of stalagmite.
