[Hyperlipoproteinemia in pregnancy]

Why does a high-fat diet induce preeclampsia-like symptoms in pregnant rats

Changes in neurotransmitter levels in the brain play an important role in epilepsy-like attacks after pregnancy-induced preeclampsia-eclampsia. Metabotropic glutamate receptor 1 participates in the onset of lipid metabolism disorder-induced preeclampsia. Pregnant rats were fed with a high-fat diet for 20 days. Thus, these pregnant rats experienced preeclampsia-like syndromes such as tension and proteinuria. Simultaneously, metabotropic glutamate receptor 1 mRNA and protein expressions were upregulated in the rat hippocampus. These findings indicate that increased sion of metabotropic glutamate receptor 1 promotes the occurrence of high-fat diet-induced preeclampsia in pregnant rats.

PAdvances in treatment of hyperlipidemic pancreatitis in pregnancy Hong-Mei Han, Xi-Xu Piao

Acute pancreatitis is a serious complication of pregnancy. In recent years, hypertriglyceridemia has become a common cause of acute pancreatitis, and up to 56% of pancreatitis cases during pregnancy are caused by hypertriglyceridemia. The majority of cases of hyperlipidemic pancreatitis in pregnancy belong to severe pancreatitis, and are commonly seen in the second and third trimester, easily recurrent, and dangerous. As hyperlipidemic pancreatitis in pregnancy is associated with a perinatal and maternal mortality of 20% to 50%, it seriously threatens maternal health and fetal lives. Now great efforts have been made to reduce the incidence of this complication and deaths of mothers and fetuses, and avoid the deformity of the baby. This article aims to review the progress in the treatment of hyperlipidemic pancreatitis in pregnancy.

[Diabetes and pregnancy]

Metabolic characteristics of physiological and diabetic pregnancies are discussed. The basic factor of these changes is the increasing insulin resistance throughout pregnancy, which in case of diabetes may result in hyperglycemia with undesirable clinical consequences and complications for both the mother and the fetus. Prevention of these complications by maintaining physiological metabolic state of diabetic pregnant women is possible, which is similar to that of healthy women. The aim of treatment of pregnant diabetics is to achieve normoglycemic state during the whole gestation that is possible by early diagnosis in case of gestational diabetes and by adequate preconception care in case of pregestational diabetes. To obtain desirable glycemic conditions insulin treatment is necessary in most of the cases together with adequate, quantitative nutrition therapy, while oral antidiabetic drugs during pregnancy and lactation are to be avoided. For adequate care of the cases with diabetes and pregnancy interdisciplinary diabetes centers with well-trained experts are required.
