研究目的: |
子痫前期(preeclampsia,PE)是一种妊娠期特有疾病,其伴随的肾损伤在疾病进程中占据关键地位。三磷酸肌醇受体(Inositol 1,4,5-trisphosphate receptor,IP3R)介导的钙离子(calcium ion,Ca2?)释放被认为是 NLRP3 炎性小体(NLRP3 inflammasome,NLRP3)激活的核心环节。本团队初步实验证据显示,在子痫前期小鼠模型中,肾损伤的发生发展可能与 IP3R 功能异常以及细胞焦亡(pyroptosis)过程紧密相关。基于此发现,本研究旨在从临床样本分析、动物实验模型构建以及体外细胞实验三个层面,系统且全面地观察子痫前期模型中钙离子动员、NLRP3 炎性小体激活、细胞焦亡现象及其与肾脏损伤之间的复杂关联与相互作用机制。本研究的核心目标是深入揭示子痫前期肾损伤过程中细胞焦亡发生的分子机制,期望为病理生理学理论体系提供创新性见解,并为未来子痫前期的临床诊疗实践开拓潜在的、新的干预方向与策略思路。 |

Objectives of Study: |
Preeclampsia, a hypertensive disorder of pregnancy, is characterized by significant renal impairment that plays a pivotal role in its pathogenesis. The release of calcium ions mediated by the Inositol 1,4,5-Trisphosphate Receptor (IP3R) is regarded as a central mechanism in the activation of the NLRP3 inflammasome. Our preliminary experimental data indicate a potential correlation between renal injury in preeclampsia mice and the interplay between IP3R and pyroptosis. This study aims to conduct a comprehensive analysis of calcium ion dynamics, NLRP3 inflammasome activation, pyroptosis, and their correlation with renal injury in preeclamptic models across distinct levels. To elucidate the intricate mechanisms by which pyroptosis contributes to renal damage in preeclampsia, offering novel insights into its pathophysiology and potentially identifying new therapeutic targets for clinical intervention. |

纳入标准: |
所以产妇均为单胎妊娠,子痫前期伴蛋白尿孕妇指在妊娠20 周后出现高血压(血压>=140/90 mmHg)和蛋白尿(24小时尿蛋白量>=300 mg),以及没有先前高血压病史。严重先兆子痫的诊断还包括更高的血压读数(收缩压>=160 mmHg 和/或舒张压>=110 mmHg)、更严重的蛋白尿(24 小时尿蛋白量>=2 g)、子痫前兆或子痫、HELLP 综合征或急性肺水肿。 |
||||||||||||||||||||||
|
Inclusion criteria |
All parturients were singleton pregnancies. Preeclampsia with proteinuria is defined as the onset of hypertension (BP >= 140/90 mmHg) and proteinuria (24-hour urine protein >= 300 mg) after 20 weeks of gestation, in the absence of prior hypertension. Severe preeclampsia is diagnosed with higher blood pressure readings (systolic BP >= 160 mmHg and/or diastolic BP >= 110 mmHg), more severe proteinuria (24-hour urine protein >= 2 g), signs of preeclamptic convulsions or eclampsia, HELLP syndrome, or acute pulmonary edema. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study employs a paper-based data collection method for data management. Researchers promptly, completely, and accurately transcribe the data from the subjects' original observational records into case report forms (CRFs). The data entry and management tasks are delegated to third-party data management personnel. After the CRFs have been completed with data entry and verification as required, a data review meeting is convened. At this meeting, the principal investigator, the project leader from the clinical research institute, the data manager, and biostatistical professionals review the trial data, make decisions on issues raised in the database audit report, and compile a data audit report. |
