To observe the influence of gestational diabetes over placental morphology, a prospective study was taken for 28 gestational diabetic pregnancies and 25 non-diabetic control subjects. Placental net weight in diabetic group is 549.38 +/- 143.01 g; in control group 458.75 +/- 60.98 g, significant difference was found between above two groups. The changes of diabetic placentas in light microscopy shows villous immaturity, proliferation of small fetal vessels, syncytiotrophoblast knots, cytotrophoblast and vessel syncytiotrophoblast membrane increased. Morphohistometric investigations showed that the changes of placenta in gestational diabetes are significant.
为观察妊娠期糖尿病对胎盘形态的影响，对28例妊娠期糖尿病孕妇及25例非糖尿病对照者进行了一项前瞻性研究。糖尿病组胎盘净重为549.38±143.01g；对照组为458.75±60.98g，两组间差异有统计学意义。糖尿病胎盘的光镜下改变显示绒毛不成熟、胎儿小血管增生、合体滋养层结节、细胞滋养层及血管合体滋养层膜增加。形态组织计量学研究表明，妊娠期糖尿病胎盘的变化具有显著性。
