Dictamnine alleviates DSS-induced colitis mice by inhibiting ferroptosis of enterocytes via activating Nrf2-Gpx4 signaling pathway.

Background: The treatment of ulcerative colitis (UC) remains a huge challenge worldwide. Dictamnine is a natural product derived from Dictamnus dasycarpus Turcz. root bark and possesses multi-pharmacological properties, including anti-inflammation effects.

Monotropein inhibits epithelial-mesenchymal transition in chronic colitis via the mTOR/P70S6K pathway.

Introduction: Patients with chronic colitis are at risk of developing intestinal fibrosis through epithelial-mesenchymal transition (EMT). Monotropein (MON) is the main active ingredient in the traditional Chinese medicine . It has been reported that monotropein can improve ulcerative colitis, but the mechanism remains unclear.

[Advances in the study of viruses inhibiting the production of advanced autophagy or interferon through Rubicon to achieve innate immune escape].

The innate immune response is the first line of defense for the host against viral infections. Targeted degradation of pathogenic microorganisms through autophagy, in conjunction with pattern recognition receptors synergistically inducing the production of interferon (IFN), constitutes an important pathway for the body to resist viral infections. Rubicon, a Run domain Beclin 1-interacting and cysteine-rich domain protein, has an inhibitory effect on autophagy and IFN production.

Necroptosis in bacterial infections.

Necroptosis, a recently discovered form of cell-programmed death that is distinct from apoptosis, has been confirmed to play a significant role in the pathogenesis of bacterial infections in various animal models. Necroptosis is advantageous to the host, but in some cases, it can be detrimental. To understand the impact of necroptosis on the pathogenesis of bacterial infections, we described the roles and molecular mechanisms of necroptosis caused by different bacterial infections in this review.

Cardioprotective Effect of Gynostemma pentaphyllum against Streptozotocin Induced Cardiac Toxicity in Rats via Alteration of AMPK/Nrf2/HO-1 Pathway.

Gynostemma pentaphyllum (GP) is a plant commonly used in diabetic therapy in China. GP having potent antioxidant effect against various free radicals. The purpose of the current investigation to identify the cardioprotective effect of GP against streptozotocin (STZ)/ high fat diet (HFD) induced cardiac dysfunction in rats via alteration of AMPK/Nrf2/HO-1 pathway.

The effect of physical exercise on circulating brain-derived neurotrophic factor in healthy subjects: A meta-analysis of randomized controlled trials.

Objective: To investigate how physical exercise (PE) would affect brain-derived neurotrophic factor (BDNF) in randomized controlled trials (RCTs) of healthy subjects.

Methods: Seven databases (PubMed, Web of Science, Cochrane, Embase, PsycINFO, CINAHL, SPORTDiscus) were searched for RCTs assessing the effects of PE on serum and/or plasma BDNF until December 18, 2021. Meta-analysis was performed by random-effects method with standardized mean difference (SMD) and 95% confidence intervals (CIs).

Malnutrition and Risk of Mortality in Ischemic Stroke Patients Treated With Intravenous Thrombolysis.

Background And Purpose: Malnutrition is highly prevalent in ischemic stroke patients. We aimed to investigate whether malnutrition indexes may be useful in predicting mortality at 90 days in ischemic stroke patients treated with intravenous thrombolysis.

Methods: We retrospectively analyzed consecutive patients who underwent thrombolytic therapy at three comprehensive stroke centers.

Cycloastragenol alleviates airway inflammation in asthmatic mice by inhibiting autophagy.

Cycloastragenol (CAG), a secondary metabolite from the roots of , has been reported to exert anti‑inflammatory effects in heart, skin and liver diseases. However, its role in asthma remains unclear. The present study aimed to investigate the effect of CAG on airway inflammation in an ovalbumin (OVA)‑induced mouse asthma model.

High flow nasal cannula therapy for obstructive sleep apnea in adults.

Purpose: Obstructive sleep apnea hypopnea syndrome (OSAHS) is characterized by the aggravation of upper airway constriction or obstruction, and it is associated with high incidence of various metabolic diseases and high mortality. Continuous positive airway pressure (CPAP) is now recommended as the first-line therapy for OSAHS, but its application is limited by its unsatisfactory patient tolerance. Previous studies have showed that high flow nasal cannula (HFNC) may improve symptoms in some patients with OSAHS.
