Quantification of diaphragmatic dynamic dysfunction in septic patients by bedside ultrasound.

Although diaphragmatic dysfunction is an important indicator of severity of illness and poor prognosis in ICU patients, there is no convenient and practical method to monitor diaphragmatic function. This study was designed to analyze diaphragmatic dynamic dysfunction by bedside ultrasound in septic patients and provide quantitative evidence to assess diaphragm function systematically. This prospective observational study was conducted from October 2019 to January 2021 in the Department of Respiratory and Critical Care Medicine.

Open-Air Dual-Diamination of Aromatic Aldehydes: Direct Synthesis of Azolo-Fused 1,3,5-Triazines Facilitated by Ammonium Iodide.

A new and practical protocol for the synthesis of medicinally privileged azolo[1,3,5]triazines by simply heating under air has been presented. The in situ generated -azolo amidines from commercially available aromatic aldehydes and 3-aminoazoles with ammonium iodide undergo the second diamination to accomplish the [3 + 1 + 1 + 1] heteroannulation reaction. This convenient process is appreciated by high efficiency, broad substrate scope, gram-scale synthesis, and operational simplicity under reagent-free conditions.

Transformation of Protopanaxadiol Saponins in Human Intestinal Flora and Its Effect on Intestinal Flora.

Protopanaxadiol (PPD)-type ginsenosides are the main ginsenosides in ginseng ( C. A. Meyer) with potential therapeutic effects on diseases related to intestinal flora imbalance.

Biotransformation of Ginsenosides (Rb , Rb , Rb , Rc) in Human Intestinal Bacteria and Its Effect on Intestinal Flora.

Ginsenosides, including Rb , Rb , Rb and Rc, belong to protopanaxadiol-type saponins in Panax ginseng C. A. Mey.

Astragaloside IV attenuates chronic intermittent hypoxia-induced myocardial injury by modulating Ca homeostasis.

Obstructive sleep apnea syndrome (OSAS) is an important consequence of chronic intermittent hypoxia (CIH). Astragaloside IV (AS-IV) exerts multiple protective effects in diverse diseases. However, whether AS-IV can attenuate CIH-induced myocardial injury is unclear.

Biotransformation of anthocyanins from Rupr of "Beibinghong" extract by human intestinal microbiota.

1. Anthocyanins (ACNs) are a subclass of polyphenolic pigments belonging to the flavonoids and constitute an important group of human diets. There is accumulated evidence that consumption of ACN-rich diets such as Rupr of "Beibinghong" exerts protective activities against some human diseases.
