摘　　要：目的:应用M型超声和定量组织速度成像技术(QTVI)分析评价正常健康人群膈肌运动功能,探讨QTVI在观察膈肌运动中的应用价值。方法:选择43名志愿者,均为健康成年人,其中男22例,女21例,平均年龄(37.5±4.3)岁。应用M型超声分别获得右侧膈肌在平静呼吸和深呼吸状态下运动幅度及收缩持续时间、收缩强度;应用QTVI在膈肌同一点获得膈肌在平静呼吸和深呼吸状态下的运动幅度、收缩持续时间及收缩强度;应用QTVI获取同一呼吸运动周期膈肌不同点的位移-时间曲线图。分别比较2种方法在平静呼吸和深呼吸状态下膈肌运动所获得参数的差异;分析深呼吸状态下2种方法测得的膈肌运动幅度、收缩强度与肺功能的相关性;观测同一呼吸运动周期膈肌不同点的位移-时间曲线图,分析其运动的同步性。结果:在平静呼吸以及深呼吸状态下,QTVI所获得的膈肌运动的幅度与M型超声测量的数据相差异均无统计学意义(P>0.05);在平静呼吸以及深呼吸状态下,2种方法所获得的膈肌收缩持续时间及收缩强度差异均无统计学意义(P>0.05);在深呼吸状态下2种方法所获得的膈肌运动幅度、收缩强度与肺功能具有较强的正相关关系(P<0.01);正常人群同一呼吸运动周期内膈肌运动具有同步性。结论:应用M型超声及QTVI可以量化评价膈肌的收缩运动,正常人同一呼吸运动周期内膈肌运动具有同步性。Objective:To analyze and evaluate the diaphragm motor function in normal healthy people on the basis of M-mode ultrasound,and explore the application value of tissue Doppler in observing the diaphragm motor function.Methods:A total of 43 healthy volunteers were selected,including 22 males and 21 females,with an average age of(37.5±4.3)years.The M-mode ultrasound was used to obtain the motion amplitude of right diaphragm under calm breathing and deep breathing,and duration and intensity of diaphragm contraction.The range of motion,duration of contraction and intensity of diaphragm under calm breathing and deep breathing were measured by tissue Doppler at the same point of the diaphragm.The tissue Doppler was used to obtain the displacement-time curves of diaphragm at different points during the same respiratory cycle.The parameters obtained by the two methods in calm breathing and deep breathing were compared between two groups.The correlations between the diaphragm motion amplitude and systolic strength measured by the two methods,and lung function were analyzed.The displacement-time curves of the diaphragm at different points in the same respiratory movement period were observed to analyze the synchronicity of the movement.Results:In calm breathing and deep breathing,there was no statistical significance in the amplitude of diaphragm movement between the obtained by quantitative tissue Doppler analysis and that measured by M-mode ultrasound(P>0.05).The differences of the duration and intensity of diaphragm contraction between the two methods in calm breathing and deep breathing were not statistically significant(P>0.05).In the state of deep breathing,there was a strong positive correlation between diaphragm motion amplitude and systolic strength,and lung function obtained by two methods(P<0.01).The diaphragmatic movement of normal people in the same respiratory movement cycle has synchronization.Conclusions:The quantitative analysis of tissue Doppler ultrasound can quantitatively evaluate the contractive motion
