摘要:
目的 探讨子痫前期胎盘滋养层细胞P53和LncRNA TINCR表达及胎盘滋养层细胞凋亡情况。 方法 选择金华市中心医院于2018年6月—2020年6月收治的子痫前期孕妇98例作为研究对象; 另选择正常妊娠孕妇50例作为对照组。取胎盘组织,采用半定量逆转录多聚酶链式反应(reverse transcription polymerase chain reaction,RT-PCR)检测P53和LncRNA TINCR表达; 取胎盘组织,采用化学发光法测定Bax和Bcl-2蛋白表达。比较各组P53和LncRNA TINCR相对表达量,Bax和Bcl-2蛋白表达。 结果 子痫前期组P53相对表达量(5.09±1.26)和LncRNA TINCR相对表达量(3.79±0.83)高于对照组(1.32±0.36、1.09±0.31),差异具有统计学意义(t=20.699、22.195,均P < 0.05)。子痫前期组Bax蛋白表达(0.65±0.14)低于对照组(1.28±0.36),而Bcl-2蛋白表达(1.26±0.16)高于对照组(0.67±0.23),差异具有统计学意义(t=15.248、18.208,均P < 0.05)。 结论 子痫前期胎盘滋养层细胞P53和LncRNA TINCR表达异常升高,胎盘滋养层细胞凋亡水平增加。 -

Abstract:Objective This study aimed to investigate the expression of P53 and lncRNA TINCR and apoptosis of placental trophoblast cells in preeclampsia. Methods A total of 98 cases of preeclampsia who were hospitalised in Jinhua Central Hospital from June 2018 to June 2020 were included in the study; 50 normal pregnant women were selected as the control group. Semi-quantitative reverse transcription polymerase chain reaction was used to detect the expression of P53 and lncRNA TINCR, and the expression of Bax and Bcl-2 was detected by chemiluminescence. The expression of P53, lncRNA TINCR, Bax and Bcl-2 protein was compared. Results The relative expression of p53 (5.09±1.26) and lncRNA TINCR (3.79±0.83) in the preeclampsia group was higher than that in the control group (1.32±0.36 and 1.09±0.31, t=20.699, 22.195, all P < 0.05). The expression of Bax in the preeclampsia group (0.65±0.14) was lower than that in control group (1.28±0.36), whereas the expression of Bcl-2 (1.26±0.16) was higher than the control group (0.67±0.23, t=15.248, 18.208, all P < 0.05). Conclusion The expression of P53 and lncRNA TINCR in placental trophoblast cells of preeclampsia is abnormally increased, and the apoptotic level of placental trophoblast cells is increased. -
