摘　　要：目的探讨高原世居藏族、高原移居汉族和平原世居汉族肝脏大小、门静脉内径及血流速度超声测量值的差异。方法超声测量151例高原世居藏族、100例平原世居汉族和95例高原移居汉族肝右叶最大斜径、肝左叶长径、肝左叶厚度、门静脉内径和门静脉血流速度,对测量结果进行统计学分析。结果高原世居藏族组肝右叶最大斜径大于高原移居汉族组和平原世居汉族组,差异有统计学意义(P=0.016,0.001);高原世居藏族组门静脉内径大于平原世居汉族组,差异有统计学意义(P=0.040)。高原世居藏族、高原移居汉族和平原世居汉族各组男女之间肝右叶最大斜径、肝左叶长径、肝左叶厚度、门静脉内径和门静脉血流速度差异无统计学意义(P>0.05)。结论高原藏族肝右叶最大斜径和门静脉内径较平原汉族偏大,提示不同民族间肝脏大小及门静脉内径存在差异,可能与饮食、环境、种族遗传有关。Objective To investigate the differences of liver size,inner diameter and blood flow velocity of portal vein among plateau native Tibetan nationality,plateau migrated Han nationality and plain native Han nationality.Methods The maximum oblique diameter of the right liver lobe,long diameter and thickness of the left liver lobe,and inner diameter and blood flow velocity of the portal vein in 151 cases of plateau native Tibetan,100 cases of plain native Han people and 95 cases of plateau migrated Han people were measured by ultrasound and the detection results were statistically analyzed.Results The maximum oblique diameter of the right liver lobe in the plateau native Tibetan was greater than that in the plateau migrated Han nationality and plain native Han nationality(P=0.016,0.001);the inner diameter of the portal vein in plateau native Tibetan was greater than that in plain native Han people(P=0.040).The maximum oblique diameter of the right liver lobe,long diameter and thickness of the left liver lobe,inner diameter and blood flow velocity of portal vein had no statistically significant differences between male and female in the plateau native Tibetan nationality,plateau migrated Han nationality and plain native Han nationality(P>0.05).Conclusion The maximum oblique diameter of the right liver lobe and inner diameter of the portal vein in plateau Tibetan are greater than those in plain Han people,which suggests that the differences in liver size and inner diameter of the portal vein exist in different nationalities,which may be related with the diet,environment and racial inheritance.
