Background: This study was performed to investigate clinical features of patients with severe SARS-CoV-2 pneumonia and identify risk factors for converting to severe cases in those who had mild to moderate diseases at the start of the pandemic in China.

Methods: In this retrospective, multicenter cohort study, patients with mild to moderate SARS-CoV-2 pneumonia were included. Demographic data, symptoms, laboratory values, and clinical outcomes were collected.

Chemoresistance has been associated with increased reliance on mitochondrial functions in many cancers, including lung cancer. Atovaquone is an anti-malaria drug and mitochondrial inhibitor. In this work, we attempted to explore whether atovaquone can be repurposed for lung cancer treatment to overcome chemoresistance.

Background: The 2019 novel coronavirus (2019-nCoV) causing an outbreak of pneumonia in Wuhan, Hubei province of China was isolated in January 2020. This study aims to investigate its epidemiologic history, and analyze the clinical characteristics, treatment regimens, and prognosis of patients infected with 2019-nCoV during this outbreak.

Methods: Clinical data from 137 2019-nCoV-infected patients admitted to the respiratory departments of nine tertiary hospitals in Hubei province from December 30, 2019 to January 24, 2020 were retrospectively collected, including general status, clinical manifestations, laboratory test results, imaging characteristics, and treatment regimens.

Lung cancer is the leading cause of mortality due to tumor malignancy worldwide. In recent years, the treatment of lung cancer with chemotherapy has demonstrated notable resistance and insensitivity. Therefore, it is of great importance to investigate anti‑lung cancer drugs with high efficiency and low toxicity.

Lower serum level of 25-hydroxyvitamin D is associated with several negative outcomes. However, previous studies have indicated that 25-hydroxyvitamin D is associated with lung cancer risk and survival, but presented controversial results.PubMed and Embase databases were searched update to August 2017 to identify and quantify the potential association between 25-hydroxyvitamin D and lung cancer risk and survival.

Purpose: To investigate the relationship between microRNA (miR)-17-5p, miR-92a, and let-7b expression and resistance to the non-small cell lung cancer (NSCLC) targeted drug Gefitinib.

Methods: The human NSCLC cell line A549 and its drug resistant strain A549/GR (Gefitinib Resistant) was used in this study. The expression of miR-17-5p, miR-92a, and let-7b in different NSCLC cell lines was detected before and after transfection using real-time fluorescent PCR.

Aim: We investigate the suitability of circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) in non-small-cell lung cancer management, which is challenging in conventional biopsies.

Materials & Methods: We performed serial blood extraction from 120 patients of varying EGFR status. Molecular profiling was performed using droplet digital PCR and correlated to survival outcome.

Heat-shock protein (Hsp) 70, known as a pro-survival protein, is aberrantly expressed in several malignancies. The small molecule 2-phenylethyenesulfonamide (PES), also referred to as pifithrin-μ, is known as an HSP70 inhibitor, which exhibits antitumor activities in a variety of cancer cell lines. However, little is known about its effect on non-small cell lung cancer (NSCLC) cell lines.

Monitoring of non small cell lung cancer (NSCLC) patients on afatinib after acquired resistance to 1 generation tyrosine kinase inhibitors is important. Circulating tumor DNA (ctDNA) offers an attractive means other than conventional tissue biopsy to characterize real time dynamic changes of the disease. In our study, we aim to ascertain the clinical value for ctDNA monitoring of NSCLC patients with acquired resistance for afatinib treatment.

Aberrant activation of oncoproteins such as members of the Ras family is common in human lung cancers. The proper function of Ras largely depends on a post-translational modification termed prenylation. Bisphosphonates have been shown to inhibit prenylation in cancer cells.

Background: The coexistence of emphysema and pulmonary fibrosis is known as combined pulmonary fibrosis and emphysema (CPFE). The aim of this study was to compare diaphragmatic motion measured by M-mode ultrasonography of patients with CPFE, idiopathic pulmonary fibrosis (IPF), and chronic obstructive pulmonary disease (COPD).

Methods: Pulmonary function, high-resolution computed tomography (HRCT), and diaphragmatic motion were examined in patients with CPFE (n = 25), IPF (n = 18), and COPD (n = 60), and in healthy controls (n = 21).
