Gegen Qinlian Decoction improves H1N1-induced viral pneumonia by modulating the "gut microbiota-metabolomics-immune/inflammation" axis.

Background And Aim: The acute pulmonary infectious disease caused by influenza viruses is known as influenza virus pneumonia (IVP). In recent years, Gegen Qinlian Decoction (GQD) has been widely used to treat pulmonary inflammation; however, the underlying mechanism of action of GQD in IVP remains unclear. This study aimed to elucidate the molecular mechanism through which GQD improved IVP.

Multi-immunometabolomics mining: NP prevents hyperimmune in ALI by inhibiting Leucine/PI3K/Akt/mTOR signaling pathway.

Study on the Antidepressant Effect of Zhizichi Decoction by Regulating Metabolism and Intestinal Flora.

Background: The incidence of depression is increasing year by year, and Zhizichi Decoction（ZZCD）has shown significant efficiency in the clinical treatment of mild depression, but its mechanism of action is still unclear. In this research, network pharmacology and metagenomics combined and metabolomics were used as research methods to explain the scientific connotation of the antidepressant effect of ZZCD from the aspects of the overall effect of organisms and microbial structure and function.

Methods: The rat model of depression was established by chronic unpredictable mild stress (CUMS), and the improvement of depressive symptoms was evaluated by behavioral and histopathological methods.

The impact and fate of clarithromycin in anaerobic digestion of waste activated sludge for biogas production.

Clarithromycin retained in waste activated sludge (WAS) inevitably enters the anaerobic digestion system. So far, the complex impacts and fate of clarithromycin in continuous operated WAS anaerobic digestion system are still unclear. In this study, two semi-continuous long-term reactors were set up to investigate the effect of clarithromycin on biogas production and antibiotic resistance genes (ARGs) during WAS anaerobic digestion, and a batch test was carried out to explore the potential metabolic mechanism.

Impact of roxithromycin on waste activated sludge anaerobic digestion: Methane production, carbon transformation and antibiotic resistance genes.

The macrolide antibiotic roxithromycin is widely detected in varying aquatic environments, especially in the wastewater systems, as an emerging contaminant and leads to significant impacts on the microorganisms involved. In this study, the impact of a shock load of roxithromycin on waste activated sludge (WAS) anaerobic digestion was comprehensively investigated. The biochemical methane potential tests showed that the methane production from WAS anaerobic digestion was significantly inhibited by roxithromycin.
