Vascular wall pregnancy hypertension

Pregnancy-induced hypertension (PIH) is a syndrome of impaired multi-organ function characterized by hypertension, proteinuria, and edema that occurs more than 20 weeks after pregnancy. The first report is more than 100 years ago, and it still seriously threatens the safety and health of mothers and infants. There are many theories about its cause and pathological changes, but so far no conclusion has been reached. Studies have shown that the occurrence of PIH is related to factors such as immune imbalance, vascular endothelial cell damage, increased intracellular Ca2 + concentration, and nitric oxide (NO). This article summarizes its research progress as follows. 1. Pregnancy-induced hypertension and immune imbalance In normal pregnancy, the response to fetal rejection (such as killer T cell activity, complement-binding antibodies, macrophage and NK cell activity, etc.) decreases, and the fetal Increased protective response (eg, increased production of blocking antibodies). Studies have suggested that the occurrence of pregnancy-induced hypertension is related to immune imbalance, and the changes in its immune system are positive.

Weak vessel wall

Congenital weak vascular wall membrane

Easy to cause varicose veins

The main reason for the formation of varicose veins is that the congenital vascular wall is relatively weak or the same posture has been changed for a long time, or the cold blood vessels have contracted and hardened. Symptoms of blood vessels protruding from the skin surface usually occur in the lower limbs, and the hands and face will varicose because of frequent exposure to cold air and cold water.
