子宫结合带(uterine junction zone,JZ)是MRI(magnetic resonance imaging)上显示的子宫壁正常结构,JZ在MRI上呈低信号,JZ具有调节滋养细胞植入、利于精子运输、月经期止血及局部免疫等功能,对于维持子宫的生理功能具有重要意义。JZ与子宫腺肌症、子宫肌瘤等的发生密切相关。本文就子宫结合带的生理功能以及其相关疾病作一简单阐述。
The uterine junction zone (JZ) is the normal structure of the uterine wall displayed on magnetic resonance imaging (MRI). JZ has a low signal on MRI. JZ has the ability to regulate the implantation of trophoblasts and facilitate sperm transport, menstrual bleeding and local Immune and other functions, for maintaining the physiological function of the uterus is of great significance. JZ and adenomyosis, uterine fibroids, etc. are closely related. This article describes the physiological function of the uterine band and its related diseases.
