Many adult patients with Fontan circulation are treated with antithrombotic agents, including direct oral anticoagulants (DOACs). However, few studies have investigated the efficacy, feasibility, and safety of DOACs in adult patients with Fontan circulation.

In this retrospective cohort study, clinical records of 139 adult patients with Fontan circulation (70 females, 50.4%) from April 2015 to March 2018 were reviewed and classified into five groups according to the therapeutic agents used DOAC (n=36), vitamin K antagonist (VKA; n=41), antiplatelet drug (n=43), combination of an antiplatelet and anticoagulant (n=14), and no-antithrombotic prophylaxis (n=5). In a 1114-patient-year follow-up, 28 major events occurred, including 10 thrombotic and 18 bleeding events; 11 of 18 (61%) female patients had severe menorrhagia. The incidence (% patient-years) of major events was 0.6, 1.42, 3.74, and 5.13 in the DOAC, antiplatelet, VKA, combination, and no-antithrombotic groups, respectively. The Cox proportional hazards analysis revealed that the DOAC group had a lower rate of primary endpoints than the VKA group in males.

DOAC may be a safe antithrombotic agent for use in adult patients with Fontan circulation, particularly in males. However, these findings should be confirmed in multi-institutional prospective studies.

Pfaffia glomerata roots are widely used in Brazil to treat various pathological conditions, particularly psychological disorders. 20-hydroxyecdysone, a phytosteroid present in the plant, can promote greater body resistance against exogenous and endogenous stressors. The objective of this study was to evaluate the possible neuroprotective effect of a 20-hydroxyecdysone-enriched fraction (20E-EF), obtained from P. glomerata roots, in an acute murine stress model.

The 20E-EF was obtained by partitioning the methanol extract from P. glomerata roots with dichloromethane. Mice were treated by gavage with three doses of 20E-EF (3, 10, and 30mg/kg) and parameters of stress, anxiety, and depression were evaluated. Biomarkers of oxidative stress (enzymes, antioxidant profile, and oxidized molecules) were evaluated in the cortex, striatum (basal ganglia), and hippocampus of animals treated with 30mg/kg of 20E-EF.

Mass spectrometry revealed that 20E was the main compound in the dichloromethane fraction. At a dose of 30mg/kg, 20E-EF reduced stress, anxiety, and depression, while stimulating antioxidant enzymes (catalase, superoxide dismutase, and glutathione peroxidase), promoting antioxidant activity (antioxidant capacity, sulfhydryl groups, and reduced glutathione), and reducing oxidative markers (lipid peroxidation). In addition, 20E increased the concentration of NO in the striatum, possibly improving memory function and antioxidant activity.

A 30mg/kg dose of 20E-EF was able to reduce stress, anxiety, and depression, in addition to maintaining antioxidant defenses of the cortex and striatum. These findings open new perspectives for understanding the therapeutic properties of P. glomerata and the underlying mechanism(s).

Dendrobium chrysotoxum Lindl is a cultivation of Dendrobium which belongs to the family of Orchidaceae. D. chrysotoxum Lindl is a traditional Chinese medicine with a wide range of clinical applications including tonic, astringent, analgesic and anti-inflammatory properties as early as the 28th century B.C. Erianin is a representative index component for the quality control of the D. chrysotoxum Lindl, which is included in the Pharmacopoeia of the People’s Republic of China (2020 version).

To clarify the anti-tumour mechanisms of erianin in vitro and in vivo.

We detected the anti-tumour activity of erianin using in vitro HeLa cell models and in vivo cervical cancer xenograft models. We performed MTT, western blot, RT-PCR, homology modeling, flow cytometry, and immunoprecipitation assays to study the proteins, genes, and pathways related to erianin’s anti-tumour activity. check details LysoTracker Red staining was performed to detect lysosome function. Transwell, wound healing, tube formation, colony formation and EdU erapy against cervical cancer and other malignant tumours through PD-L1.

Collectively, these results revealed previously unknown properties of erianin and provided a new basis for improving the efficacy of immunotherapy against cervical cancer and other malignant tumours through PD-L1.

Nardostachys jatamansi (D.Don) DC. (family Caprifoliaceae, NJ) is well-documented and commonly used in the systems of traditional medicine in China, Tibet, Nepal, Bhutan, India and Japan for curing digestive and neuropsychiatric disorders with a long history of medication. However, the possible action mechanisms of antidepressant effects of NJ remain unraveled.

The aim of this study was to systematically investigate chemical substances of NJ and their effects on serotonin transporter (SERT) in antidepressant activity.

Antidepressant effects of total methanol extract of NJ were evaluated by tail suspension test (TST) and open field test (OFT). Then the total extract was analyzed by ultra-high-performance liquid chromatography (UHPLC) method, and its effect on SERT activity was evaluated by high content assay (HCA) to determine half maximal effective concentration (EC

). This total extract was subfractioned into twenty subfractions by preparative high-performance liquid chromatography (p-HPLC) method, annstituents demonstrated the major components of fraction NJFr.01 enhanced SERT activity. Antagonistic results showed that chlorogenic acid and desoxo-narchinol A reversed inhibition effect of fluoxetine on SERT activity.

This study first systematically expatiated the roles of SERT activity in antidepressant effects of NJ, including total methanol extract and the water-soluble fraction NJFr.01 enriched with SERT enhancing constituents. This is the first report of natural SERT enhancing extract and fractions with antidepressant potential in NJ.
