摘要:

目的 分析子痫前期患者胎盘环状RNA(circRNA)表达谱基因表达情况及其与患者病情的相关性。方法 选取子痫前期患者(子痫前期组)15例,重度子痫前期患者(重度子痫前期组)25例及正常妊娠女性(对照组)30例。收集患者临床资料,检测各组24 h尿蛋白定量;采用酶联免疫吸附试验检测血清中的STOX1蛋白、血清可溶性血管内皮生长因子受体1(sFlt-1)、胎盘生长因子(PLGF)及血管内皮生长因子(VEGF)水平。于胎盘娩出后收集胎盘组织,检测胎盘circRNA表达情况,选取上调及下调基因各自差异表达水平由高到低排名前3位的基因进行分析;分析孕妇差异表达基因与24 h尿蛋白定量、平均动脉压、STOX1、sFlt-1、PLGF和VEGF的相关性;采用多元线性回归模型分析影响孕妇24 h尿蛋白定量的相关因素。结果 与对照组比较,子痫前期组及重度子痫前期组的孕前体质量指数和平均动脉压升高(P<0.05);对照组、子痫前期组及重度子痫前期组24 h尿蛋白定量、STOX1、sFlt-1、胎盘hsa_circ_0014736、hsa_circ_0015383及hsa_circ_0004904表达水平依次升高,而hsa_circ_0063517、hsa_circ_0007121及hsa_circ_0003171表达水平依次降低(P<0.05);子痫前期组及重度子痫前期组hsa_circ_0014736、hsa_circ_0015383及hsa_circ_0004904分别与BMI、平均动脉压、24 h尿蛋白定量、STOX1、sFlt-1呈正相关,与VEGF、PLGF呈负相关(P<0.05),而hsa_circ_0063517、hsa_circ_0007121及hsa_circ_0003171与临床特征的相关性与此相反(P<0.05)。多元线性回归分析显示,hsa_circ_0015383与孕妇24 h尿蛋白定量呈正向线性相关,hsa_circ_0063517及hsa_circ_0007121与孕妇24 h尿蛋白定量呈负向线性相关(P<0.05)。结论 子痫前期孕妇胎盘中hsa_circ_0063517及hsa_circ_0007121表达水平下调,hsa_circ_0015383表达水平上调,与患者病情密切相关。

Abstract:

Objective To analyze expression profile of circular RNA (circRNA) in placenta of patients with preeclampsia and its correlation with the patients' condition. Methods A total of 15 patients with preeclampsia (the preeclampsia group), 25 patients with severe preeclampsia (the severe preeclampsia group), and 30 normal pregnant women (the control group) were selected. Clinical data of patients were collected. 24 h urinary protein levels were detected in each group. Serum STOX1 protein, serum soluble vascular endothelial growth factor receptor 1 (sFlt-1), placental growth factor (PLGF) and vascular endothelial growth factor (VEGF) were detected by enzyme-linked immunosorbent assay. The placental samples were collected after delivery, and the expression of circRNA in placenta was detected. The top three genes with differentially expressed levels of up-regulated and down-regulated genes from high to low were selected for analysis. The correlation of differentially expressed genes with 24 h urinary protein, mean arterial pressure, STOX1, sFlt-1, PLGF and VEGF in pregnant women was analyzed. Multiple linear regression model was used to analyze factors affecting the quantitative level of 24 h urine protein in pregnant women. Results Compared with the control group, there were higher prepregnancy body mass index and mean arterial pressure in the preeclampsia group and the severe preeclampsia group (P<0.05). The 24 h urinary protein quantity, STOX1, sFlt-1, hsa_circ_0014736, hsa_circ_0015383 and hsa_circ_0004904 expression levels in placenta were increased gradually in the control group, the preeclampsia group and the severe preeclampsia group. The expression levels of hsa_circ_0063517, hsa_circ_0007121 and hsa_circ_0003171 were decreased gradually (P<0.05). Values of hsa_circ_0014736, hsa_circ_0015383 and hsa_circ_0004904 were positively correlated with mean arterial pressure, 24 h urinary protein quantity, STOX1 and sFlt-1 in the preeclampsia group and the severe preeclampsia group respectively. They were negatively correlated with VEGF and PLGF (P<0.05), while hsa_circ_0063517, hsa_circ_0007121 and hsa_circ_0003171 were negatively correlated with clinical features (P<0.05). Multiple linear regression analysis showed that hsa_circ_0015383 had positive linear correlation with 24 h urinary protein quantification in pregnant women, and hsa_circ_0063517 and hsa_circ_0007121 had negative linear correlation with 24 h urinary protein quantification in pregnant women (P<0.05). Conclusion The expression levels of hsa_circ_0063517 and hsa_circ_0007121 in placenta are down-regulated in preeclampsia pregnant women, and expression levels of hsa_circ_0015383 are up-regulated, which is closely related to the patient's condition.
