When studying endocrine disruption during pregnancy, the placental steroidogenesis is difficult to model, as the human placenta is unique in the pathway of cellular uptake of cholesterol, the high levels of progesterone production and the expression of aromatase. Models to test for endocrine disruption should respect species differences, with preference to human models for human risk assessment. Here, we present existing research of placental steroidogenesis and other placental hormones using human placental models: placental perfusion, placental explants, fragments, microsomes and vesicles, primary cell culture, stem cells, placenta on a chip and choriocarcinoma cell cultures: BeWo, HTR-8/SVneo, Jar, JEG-3 and ACH-3P.

The formation and development of renal fibrosis are stimulated by pro-inflammatory as well as pro-fibrosis factors released by inflammatory cells. Wuling San is an ancient Chinese classical formula for urination-promoting and dampness-draining, which can regulate the metabolism of water and fluid and has exerted therapeutic effects on various chronic kidney diseases by reducing oedema, inflammation, and improving glomerulosclerosis and renal interstitial fibrosis. However, further study is still needed to explore the mechanism. Based on the research analysis with the help of CiteSpace, the following three directions were the possible mechanisms in improving renal fibrosis: inhibiting the conversion of renal cells to myofibroblasts; regulating amino acid, lipid and energy metabolism and reducing extracellular matrix (ECM) deposition; and regulating the RhoA/ROCK pathway, the downstream of G protein-coupled receptor (GPCR).
