Problems solved by technology

[0005] The present invention aims to solve the problem that in the prior art, the rat model of preeclampsia established by sFlt-1 constructed by injecting adenovirus into the tail vein of rats will not cause damage to multiple organs and viscera, and cannot well reflect the severity of the disease. The problem is to provide a specific method for establishing a rat model of preeclampsia and a rat model of preeclampsia by injecting Ad-sAxl into pregnant mother mice through the tail vein. The rat model of preeclampsia has elevated blood pressure, Changes in the characteristic symptoms and signs of preeclampsia, such as proteinuria and damage to important organs such as the heart, liver, and kidney, are consistent with the symptoms, signs and pathological process of human preeclampsia, and can reflect the systemicity and severity of the disease. Good controllability and stability

Abstract

The invention provides application of Ad-sAxl in the establishment of a preeclampsia rat model and an establishment method of the preeclampsia rat model. The preeclampsia rat model is established by injecting Ad-sAxl into a pregnant rat through in a caudal vein manner and has the preeclampsia characteristic symptoms and symptomatic changes including elevation of blood pressure, injuries of important organs such as proteinuria, heart, liver and kidney, and the characteristic symptoms and symptomatic changes are accordant with preeclampsia symptom, signs and pathological processes of human and can reflect the systematicness and severity of diseases; and the operational controllability and the stability are good. The application can be applied to the research of occurrence and development mechanisms and control measures of preeclampsia.

Description

technical field [0001] The invention belongs to the field of biomedicine, and specifically relates to the application of Ad-sAxl in establishing a preeclampsia rat model and a method for establishing the preeclampsia rat model. Background technique [0002] Preeclampsia is a pregnancy-specific disease characterized by elevated blood pressure and proteinuria after 20 weeks of gestation, which can involve multiple organs throughout the body and seriously threaten maternal and fetal health. The pathogenesis of preeclampsia is not yet clear, but current studies suggest that its occurrence is closely related to early trophoblast invasion disorder and spiral artery remodeling disorder, and extensive vascular endothelial injury in the body is the further development of the disease and presents various degrees. critical aspect of clinical presentation. The imbalance between pro-angiogenic and anti-angiogenic not only locally affects trophoblast invasion and spiral artery remodeling...
