Here, 72 Chinese volunteers with a wide range of body mass index (BMI) participated in a three-week IF program during which an average loss of 3.67 kg body weight accompanied with improved clinical parameters was observed irrespective of initial anthropometric and gut microbiota status.

Quercetin protects against LPS-induced lung injury in mice via SIRT1-mediated suppression of PKM2 nuclear accumulation.

The role of NOD-like receptor protein 3 (NLRP3)-mediated macrophages pyroptosis in acute lung injury (ALI) is well-established. Quercetin (Que) is a natural bioflavonoid compound with anti-inflammatory and antioxidative properties that reportedly inhibits the NLRP3 inflammasome in sepsis-induced organ dysfunctions such as ALI. However, the mechanism underlying the inhibitory effect of quercetin on NLRP3 activation remains unclear.

Intelligent automatic sleep staging model based on CNN and LSTM.

Since electroencephalogram (EEG) is a significant basis to treat and diagnose somnipathy, sleep electroencephalogram automatic staging methods play important role in the treatment and diagnosis of sleep disorders. Due to the characteristics of weak signals, EEG needs accurate and efficient algorithms to extract feature information before applying it in the sleep stages. Conventional feature extraction methods have low efficiency and are difficult to meet the time validity of fast staging.

Delayed neutrophil apoptosis may enhance NET formation in ARDS.

Background: Acute respiratory distress syndrome (ARDS) is a neutrophil-associated disease.

Human amniotic fluid derived-exosomes alleviate hypoxic encephalopathy by enhancing angiogenesis in neonatal mice after hypoxia.

Neonatal hypoxic encephalopathy is a type of central nervous system dysfunction manifested by high mortality and morbidity. Exosomes play a crucial role in neuroprotection by enhancing angiogenesis. The objective of this study was to investigate the effect of human amniotic fluid-derived exosomes (hAFEXOs) on functional recovery in neonatal hypoxic encephalopathy.

Neutrophil Extracellular Traps Augmented Alveolar Macrophage Pyroptosis via AIM2 Inflammasome Activation in LPS-Induced ALI/ARDS.

Background: Uncontrollable inflammation is a critical feature of gram-negative bacterial pneumonia-induced acute respiratory distress syndrome (ARDS). Both neutrophils and alveolar macrophages participate in inflammation, but how their interaction augments inflammation and triggers ARDS is unclear. The authors hypothesize that neutrophil extracellular traps (NETs), which are formed during neutrophil NETosis, partly cause alveolar macrophage pyroptosis and worsen the severity of ARDS.

Colonic dialysis can influence gut flora to protect renal function in patients with pre-dialysis chronic kidney disease.

Chronic kidney disease (CKD) is a major public health burden around the world. The gut microbiome may contribute to CKD progression and serve as a promising therapeutic target. Colonic dialysis has long been used in China to help remove gut-derived toxins to delay CKD progression.

Background: We investigated the dynamic changes in lipid profiles and their correlations with disease severity and clinical outcome in patients with severe COVID-19.

Methods: We retrospectively reviewed 519 severe COVID-19 patients with confirmed outcomes (discharged or deceased), admitted to the West Court of Union Hospital in Wuhan, China, between 29 January and 8 April 2020.

Results: Altogether, 424 severe COVID-19 patients, including 34 non-survivors and 390 survivors, were included in the final analyses.

A new survival model based on ion channel genes for prognostic prediction in hepatocellular carcinoma.

Accumulating studies revealed the vital role of ion channels in cancers, but the prognosis role of ion channels in hepatocellular carcinoma (HCC) remains limited. Here, we developed and validated an ion channel signature for prognostic prediction of HCC patients. In total, 35 differential expressed ion channel genes (DEChannelGs) were identified in HCC and a novel ion channel risk model was established for HCC prognosis prediction using the TCGA cohort, which was validated using the ICGC cohort.

Thyroid dysfunction may be associated with poor outcomes in patients with COVID-19.

Background: Coronavirus disease (COVID-19) has resulted in considerable morbidity and mortality worldwide. Thyroid hormones play a key role in modulating metabolism and the immune system. However, the prevalence of thyroid dysfunction (TD) and its association with the prognosis of COVID-19 have not yet been elucidated.

Canagliflozin alleviates LPS-induced acute lung injury by modulating alveolar macrophage polarization.

Background: Canagliflozin (CANA), a sodium-glucose cotransporter 2 inhibitor, is a novel therapeutic agent that exhibits multiple actions in type 2 diabetes. CANA can regulate intracellular glucose metabolism and exert anti-inflammatory effects in immune cells. Alveolar macrophage polarization balance is often associated with lower inflammation in acute lung injury (ALI).

A predictive model for the severity of COVID-19 in elderly patients.

Elderly patients with coronavirus disease 2019 (COVID-19) are more likely to develop severe or critical pneumonia, with a high fatality rate.
