To study the expression of IL-17 in peripheral blood and its effect on maternal-fetal tolerance in patients with eclampsia in late pregnancy using MRI image segmentation algorithm.
Thirty-nine patients with severe preeclampsia and eclampsia with brain symptoms were examined by cranial MRI. Pregnant women with 32 weeks of pregnancy were selected to detect the percentage of Th17 and Treg cells in CD4 + T lymphocytes and the expression of cytokines IL-17 and IL-10 in peripheral blood.
MRI examination was normal in 26 cases, 9 cases showed reversible posterior encephalopathy syndrome, three cases were cerebral hemorrhage, and one case was intracranial cavernous sinus thrombosis. two. Compared with the mild preeclampsia group, the relative number of Thl7 cells increased and that of Treg cells decreased in the severe preeclampsia group (P>0.05).
The major types of cerebrovascular diseases (CVD) in severe preeclampsia and eclampsia were reversible posterior encephalopathy syndrome and cerebral hemorrhage. It was speculated that the damage to the blood-brain barrier may play an important role in the pathogenesis. The balance of the number of Th17 cells/the number of Treg cells was more inclined to the Th17 cell-mediated pro-inflammatory state, Treg cell-mediated immune tolerance decreases, and it becomes more obvious with the worsening of the disease.
采用MRI图像分割算法研究子痫患者外周血中白细胞介素-17(IL-17)的表达及其对母胎耐受的影响。
对39例重度子痫前期及伴有脑部症状的子痫患者进行头颅MRI检查。选取孕32周的孕妇检测CD4+T淋巴细胞中Th17和调节性T细胞(Treg)的百分比以及外周血中细胞因子IL-17和IL-10的表达。
MRI检查正常26例,9例表现为可逆性后部脑病综合征,3例为脑出血,1例为颅内海绵窦血栓形成。与轻度子痫前期组相比,重度子痫前期组Th17细胞相对数量增加,Treg细胞相对数量减少(P>0.05)。
重度子痫前期和子痫患者脑血管疾病(CVD)的主要类型为可逆性后部脑病综合征和脑出血。推测血脑屏障受损可能在发病机制中起重要作用。Th17细胞数量/Treg细胞数量的平衡更倾向于Th17细胞介导的促炎状态,Treg细胞介导的免疫耐受降低,且随着病情加重而更加明显。
