【摘要】:目的:分析妊娠高血壓綜合征(PIH)患者外周血中免疫細胞因子水平變化及滋養(yǎng)層細胞中免疫相關轉(zhuǎn)錄因子的基因、蛋白表達情況,探討母-胎免疫調(diào)節(jié)機制在妊娠高血壓綜合征病理過程中的作用。方法:納入PIH患者50例作為觀察組,選擇同期分娩的正常妊娠婦女40例作為對照組。ELISA法檢測兩組孕婦外周血中IFN-γ、IL-4、IL-17及TGF-β水平;實時熒光定量PCR(RT-q PCR)法和蛋白質(zhì)印跡法(Western blot)分別測定兩組孕婦胎盤滋養(yǎng)層細胞中轉(zhuǎn)錄因子T-bet、GATA-3、RORC、Foxp3的mRNA及蛋白表達情況。結(jié)果:(1)觀察組外周血中IFN-γ和IL-17水平明顯高于對照組,TGF-β水平明顯低于對照組(P0.05);兩組間IL-4水平無明顯差異(P0.05);觀察組IFN-γ/IL-4、IL-17/TGF-β比值均明顯大于對照組(P0.05)。(2)與對照組比,觀察組T-bet、RORC的mRNA及蛋白表達水平均顯著升高(P0.05),而GATA-3、Foxp3的mRNA及蛋白表達水平均顯著降低(P0.05),T-bet/GATA-3及RORC/Foxp3比值均顯著增大(P0.05)。結(jié)論:PIH具有明顯的Th1/Th2及Th17/Treg比例失衡現(xiàn)象,其病理機制可能與Th細胞介導的母-胎免疫耐受機制功能紊亂有關。
[Abstract]:Objective: to analyze the pregnancy induced hypertension syndrome (PIH) gene immune changes in immune cytokines in the peripheral blood and trophoblast cells in the transcription factors related to patients, protein expression and regulation mechanism of maternal fetal immune syndrome in the pathological process for pregnancy induced hypertension. Methods: Sixty PIH patients 50 cases as the observation group during the same period, select 40 cases of normal pregnant women as control group.ELISA detection method IFN- two groups of pregnant women in the peripheral blood of IL-4, IL-17 and TGF- gamma, beta level; real time fluorescence quantitative PCR (RT-q PCR) and Western blotting (Western blot) transcription factor T-bet, two groups of pregnant women were measured in placental trophoblast cells GATA-3, RORC, mRNA and protein expression of Foxp3. Results: (1) observation group peripheral blood IFN- and IL-17 levels were significantly higher than the control group, TGF- levels were significantly lower than the control group (P0.05); IL-4 in the two groups no significant difference ISO (P0.05); the observation group IFN- beta gamma /IL-4, IL-17/TGF- ratio was significantly higher than the control group (P0.05). (2) compared with control group, the observation group T-bet, mRNA and protein expression levels of RORC were significantly increased (P0.05), GATA-3, mRNA and protein expression levels of Foxp3 were significantly lower (P0.05), T-bet/GATA-3 and RORC/Foxp3 ratio were significantly increased (P0.05). Conclusion: PIH has Th1/Th2 and Th17/Treg imbalance phenomenon obviously, the pathological mechanism may be mediated by Th cells in maternal fetal immune tolerance mechanism dysfunction.
