Correlation of lipid peroxidation and ATP enzyme on erythrocyte membrane with fetal distress in the uterus in patients with intrahepatic cholestasis of pregnancy

Role of ferroptosis in pregnancy related diseases and its therapeutic potential

Ferroptosis is a form of regulated cell death characterized by iron overload, overwhelming lipid peroxidation, and disruption of antioxidant systems. Emerging evidence suggests that ferroptosis is associated with pregnancy related diseases, such as spontaneous abortion, pre-eclampsia, gestational diabetes mellitus, intrahepatic cholestasis of pregnancy, and spontaneous preterm birth. According to these findings, inhibiting ferroptosis might be a potential option to treat pregnancy related diseases. This review summarizes the mechanisms and advances of ferroptosis, the pathogenic role of ferroptosis in pregnancy related diseases and the potential medicines for its treatment.

Diagnostic and prognostic value of blood inflammation and biochemical indicators for intrahepatic cholestasis of pregnancy in Chinese pregnant women

Intrahepatic cholestasis of pregnancy (ICP) is a common liver disease during pregnancy, that has serious complications. This study aimed to compare the blood inflammation and biochemical markers of pregnant women with ICP in Southwest China and analyse their diagnostic value for ICP. A controlled cross-sectional study was conducted, and routine blood and biochemical indicators of 304 diagnosed ICP patients and 363 healthy pregnant women undergoing routine prenatal examination were assessed. The blood inflammatory indicators and biochemical indicators were compared between the ICP groups and normal groups. In this study, the levels of the ALT, AST, GGT, TBIL and DBIL biochemical indicators and the levels of WBC, neutrophils, NLR and PLR inflammatory indicators in the ICP group were significantly higher than those in healthy pregnant women (p < 0.001). The PA and lymphocytes of the ICP group were significantly lower than those of the normal group (p < 0.001). ROC curves showed that ALT and the NLR had higher predictive value for ICP. The GGT, TBA and NLR of pregnant women with ICP in the preterm group were significantly higher than those in the term group, and the combined NLR and TBA had a certain predictive value for preterm birth.

Anti-Myocardial Ischemia Reperfusion Injury Mechanism of Dried Ginger-Aconite Decoction Based on Network Pharmacology

Dried ginger-aconite decoction (DAD) is a traditional Chinese medicine (TCM) formula that has been extensively used in the treatment of myocardial ischemia reperfusion injury (MI/RI). However, its specific mechanism against MI/RI has not been reported yet. Therefore, this paper studies the potential active components and mechanism of DAD against MI/RI based on network pharmacology and experimental verification. Sixteen active components of DAD were screened according to oral bioavailability and drug similarity indices. Through Cytoscape 3.7.0, a component-target network diagram was drawn, and potential active components of DAD against MI/RI were determined. Protein-protein interaction (PPI) and compound-target-pathway (C-T-P) networks were established through the software to discover the biological processes, core targets and core pathways of DAD against MI/RI. High Performance Liquid Chromatography (HPLC) analysis identified the presence of potentially active core components for network pharmacological prediction in DAD. It was found that DAD might have played a therapeutic role in anti-MI/RI by activating the PI3K/Akt/GSK-3β signaling pathway in order to reduce mitochondrial hypoxia injury and myocardial cell apoptosis. The network pharmacological prediction was validated by Hypoxia/reoxygenation(H/R) model in vitro and ligation model of the ligation of the left anterior descending branch in vivo. It was verified that DAD had activated PI3K/AKT/GSK-3β to reduce myocardial apoptosis and play a therapeutic function in MI/RI.
