A deep insight into ferroptosis in lung disease: facts and perspectives.

In the last decade, ferroptosis has received much attention from the scientific research community. It differs from other modes of cell death at the morphological, biochemical, and genetic levels. Ferroptosis is mainly characterized by non-apoptotic iron-dependent cell death caused by iron-dependent lipid peroxide excess and is accompanied by abnormal iron metabolism and oxidative stress.

Prevalence and risk factors for postinfectious cough in discharged patients with coronavirus disease 2019 (COVID-19).

Background: Cough is one of the most common symptoms of coronavirus disease 2019 (COVID-19). However, the prevalence of persistent cough in recovered patients with COVID-19 during a longer follow-up remained unknown. This study aims to investigate the prevalence, and risk factors for postinfectious cough in COVID-19 patients after discharge.

Efficacy and safety of Bufei Huoxue capsules in the management of convalescent patients with COVID-19 infection: A multicentre, double-blind, and randomised controlled trial.

Background: As of September 17, 2021, coronavirus disease 2019 (COVID-19) has infected more than 226 million people in a worldwide pandemic, with conservative estimates suggesting that there are more than 204 million convalescent patients with COVID-19. Previous studies have indicated that patients in the recovery phase exhibit decreased function of multiple organs. In China, traditional Chinese medicine (TCM) treatment is recommended in the rehabilitation period of COVID-19; however, the safety and efficacy of such treatment remain to be confirmed.

Virtual Reality Exposure Therapy (VRET) for Anxiety Due to Fear of COVID-19 Infection: A Case Series.

Virtual reality exposure therapy (VRET) is becoming popular for treating phobia and anxiety disorder. The recent pandemic of COVID-19 not only causes infection per se but also has an impact on mental health. This case series aimed to explore the role of VRET in the intervention of psychiatric illnesses with chief complaints of fear of COVID-19 infection.

Short-term outcomes of COVID-19 and risk factors for progression.

Follistatin-like 1 protects mesenchymal stem cells from hypoxic damage and enhances their therapeutic efficacy in a mouse myocardial infarction model.

Background: Cell therapy remains the most promising approach against ischemic heart injury. However, poor survival of engrafted cells in ischemic sites diminishes its therapeutic efficacy. Follistatin-like 1 (Fstl1) is documented as a novel pro-survival cardiokine for cardiomyocytes, and it is protective during ischemic heart injury.

Two-stage study of lung cancer risk modification by a functional variant in the 3'-untranslated region of based on the bone morphogenetic protein pathway.

Increasing evidence supports a key role for the bone morphogenetic protein () signaling pathway in lung vasculogenesis and angiogenesis. Genetic variations in genes have been found to be correlated with cancer risk. In particular, the mutation in the 3'-untranslated region of may significantly affect gene function, leading to cancer susceptibility.

Genetic Variants in the Hedgehog Interacting Protein Gene Are Associated with the FEV1/FVC Ratio in Southern Han Chinese Subjects with Chronic Obstructive Pulmonary Disease.

Background: Convincing evidences have demonstrated the associations between and polymorphisms and COPD in non-Asian populations. Here genetic variants in and were investigated in Southern Han Chinese COPD.

Methods: A case-control study was conducted, including 989 cases and 999 controls.

Identification of TRPCs genetic variants that modify risk for lung cancer based on the pathway and two-stage study.

Objective: Store operated calcium channels (SOCCs) and Receptor-operated calcium channels (ROCCs) are important pathways participating in regulation of intracellular Ca(2 +) concentration in various cell types. The purpose of our study is to determine whether genetic variations in key components of SOCCs and ROCCs are associated with lung cancer risk.

Methods: We identified 236 tagSNPs in 9 key genes related to SOCCs and ROCCs (TRPC1, TRPC3, TRPC4, TRPC6, TRPC7, ORAI1, ORAI2, STIM1, and STIM2) and evaluated their association with lung cancer risk in a two-stage case-control study with a total of 2433 lung cancer cases and 2433 cancer-free controls using Illumina high throughput genotyping platform.

Protein phosphatase 2A regulatory subunit B56β modulates erythroid differentiation.

Anemia due to attenuated erythroid terminal differentiation is one of the most common hematological disorders occurring at all stages of life. We previously demonstrated that catalytic subunit α of protein phosphatase 2A (PP2Acα) modulates fetal liver erythropoiesis. However the corresponding PP2A regulatory subunit in this process remains unknown.

Immunomodulation by mesenchymal stem cells in treating human autoimmune disease-associated lung fibrosis.

Background: Interstitial pneumonia in connective tissue diseases (CTD-IP) featuring inflammation and fibrosis is a leading cause of death in CTD-IP patients. The related autoimmune lung injury and disturbed self-healing process make conventional anti-inflammatory drugs ineffective. Equipped with unique immunoregulatory and regenerative properties, mesenchymal stem cells (MSCs) may represent a promising therapeutic agent in CTD-IP.

Genetic variants in MUC4 gene are associated with lung cancer risk in a Chinese population.

Mucin MUC4, which is encoded by the MUC4 gene, plays an important role in epithelial cell proliferation and differentiation. Aberrant MUC4 overexpression is associated with invasive tumor proliferation and poor outcome in epithelial cancers. Collectively, the existing evidence suggests that MUC4 has tumor-promoter functions.

Successful thrombolysis in postoperative patients with acute massive pulmonary embolism.

Purpose: The standard medical management for patients with acute massive pulmonary embolism (MPE) is systemic thrombolysis. However, it is generally thought that recent surgeries are a contraindication to thrombolytic therapy. In this study, we evaluated the efficacy and safety of systemic thrombolysis for postoperative patients with acute MPE and assessed the risk of bleeding.
