Preparation, Structures, Photoluminescence and Semiconductive Properties of Two Novel Lanthanide Mercury Materials with a 3-D Framework Structure.

Two novel lanthanide mercury materials, [Gd(IA)3(H3O)2Hg3Br6]n·2nCl (1) and [La(IA)3(H3O)2Hg3Br6]n·2nCl (2) (IA = isonicotinic anion), have been prepared under solvothermal conditions and characterized by single-crystal X-ray diffraction techniques. They are isomorphic and characterized by a three-dimensional (3-D) framework structure. The lanthanide ions are bound by eight oxygen atoms to exhibit a square antiprismatic geometry.

Placenta Accreta has a Low Association with Hypertensive Disease During Pregnancy: A Systematic Review Incorporating a Network Meta-analysis.

A meta-analysis was performed to evaluate the potential relationship between hypertensive disease during pregnancy and placenta accreta. A systematic literature search in OVID, Embase, Cochrane Library, PubMed, and Google scholar up to May 2021 was done, and 4 studies were found including 47,353 pregnant women at the start of the study; 4283 of them had hypertensive disease during pregnancy and 493 had placenta accreta. They were reporting relationships between hypertensive disease during pregnancy and placenta accreta.

Hypertension in pregnancy as a risk factor for placenta accreta spectrum: a systematic review incorporating a network meta-analysis.

Background: A meta-analysis was performed to evaluate the potential effects of hypertension in pregnancy on the placenta accreta spectrum.

Methods: A systematic literature search in OVID, Embase, Cochrane Library, PubMed, and Google Scholar up to May 2021 was done, and six studies were found including 126,224 pregnant women; 7164 of them had hypertension in pregnancy and 816 had placenta accreta spectrum. They were reporting relationships between the potential effects of hypertension in pregnancy on the placenta accreta spectrum.

[The prevent miscarriage effects of Yun Kang oral liquid on threatened abortion rat induced by kidney deficiency and luteum inhibition].

Objective: Yun Kang oral liquid is a listed proprietary Chinese Medicine. To further evaluate its efficacy, this experiment established a kidney deficiency and luteum inhibition threatened abortion rat model to observe the effects of Yun Kang oral liquid.

Methods: Sixty pregnant rats were randomly divided into normal control group (NC), model group (MG), dydrogesterone group (DT, 3.

[Efficacy of compound Dendrobium on PI3K/AKT/eNOS signaling pathway in hypertensive rats induced by "dietary disorders"].

To observe the efficacy of compound Dendrobium on Sprague Dawley rats (SD) hypertension model induced by "dietary disorders" and its relevant mechanism, totally 50 SD rats were fed with high-sugar, high-fat diet and alcohol for four weeks. According to the blood pressure after modeling, the rats were divided into model group, valsartan group (8 mg·kg⁻¹), low, medium and high-dose Dendrobium candidum compound groups (1.65, 3.

[Effect and mechanism of Yunkang oral liquid in regulating endocrine system and VEGF signaling pathway and reducing abortion rate in recurrent abortion mice].

This experiment focuses on the effect of Yunkang oral liquid on abortion rate, endocrine system and VEGF signal pathway in Clark classical recurrent abortion model mice. RSA mice were randomly divded into model group, low, middle and high-dose groups and progesterone group. The normal pregnancy mice were included into normal group.

[Secondary Metabolites from Penicillium raistrickii].

Objective: To investigate the secondary metabolites from Penicillium raistrickii.

Methods: Compounds were isolated and purified by normal and reverse phase silica gel, Sephadex LH-20 gel column chromatography and RP-HPLC. Their structures were established by means of spectral techniques and physicochemical properties.
