Association of mechanical power during one-lung ventilation and post-operative pulmonary complications among patients undergoing lobectomy: a protocol for a prospective cohort study.

The association of intra-operative mechanical power (MP) with post-operative pulmonary complications (PPCs) has been described before, but it is uncertain whether the potential inherent bias can limit the use of this parameter, particularly in the context of one-lung ventilation. This single-center study aims to investigate the effect of MP during one-lung ventilation (OLV), and the risks of PPCs in patients undergoing thoracoscopic lobectomy. This prospective observational study is being conducted in an academic tertiary hospital in mainland China.

Discovery of tetrahydroisoquinolineindole derivatives as first dual PRMT5 inhibitors/hnRNP E1 upregulators: Design, synthesis and biological evaluation.

Protein arginine methyltransferase 5 (PRMT5) is an epigenetics related enzyme that has been validated as an important therapeutic target for treating various types of cancer. Upregulation of tumor suppressor hnRNP E1 has also been considered as an effective antitumor therapy. In this study, a series of tetrahydroisoquinolineindole hybrids were designed and prepared, and compounds 3m and 3s4 were found to be selective inhibitors of PRMT5 and upregulators of hnRNP E1.

Traditional uses, phytochemistry, pharmacology and clinical applications of Cortex Juglandis Mandshuricae: A comprehensive review.

Ethnopharmalogical Relevance: Cortex Juglandis Mandshuricae (CJM) is the dry branch or stem bark of the Juglans mandshurica Maxim. and is widely used as a traditional Chinese medicine in Asia and Africa. Its use was first recorded in Kaibao Bencao.

[Comparative pharmacokinetics of syringin, eleutheroside E and isofraxidin in rat plasma after intravenous administration of each monomer and Ciwujia injection].

To compare the pharmacokinetics of syringin, eleutheroside E and isofraxidin after intravenous administration of each monomer and Ciwujia injection. Twenty-four Sprague-Dawley rats were randomly divided into four groups and intravenously administrated with syringin, eleutheroside E, isofraxidin, and Ciwujia injection, respectively. The concentrations of the three components in rat plasma were determined by LC-MS/MS.

[Study on in vivo pharmacokinetics of cucurbitacin injection in rats].

To establish a method for the determination of cucurbitacin in plasma samples, in order to study the in vivo pharmacokinetic characteristics of cucurbitacin in rats. Rats were intravenously injected with cucurbitacin. With diphenhydramine as the internal standard (IS), the plasma concentrations of cucurbitacin in rat plasma at different time points were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS).

Covalent protein binding and tissue distribution of houttuynin in rats after intravenous administration of sodium houttuyfonate.

Aim: To investigate the potential of houttuynin to covalently bind to proteins in vitro and in vivo and to identify the adduct structures.

Methods: Male Sprague-Dawley rats were intravenously injected with sodium houttuyfonate (10 mg/kg). The concentrations of houttuynin in blood, plasma and five tissues tested were determined using an LC/MS/MS method.
