There is currently an outbreak of respiratory disease caused by a novel coronavirus. The virus has been named severe acute syndrome coronavirus 2 (SARS-CoV-2) and the it causes 2019 (COVID-19). More than 16% patients developed distress syndrome, fatality ratio was 1%–2%. No specific treatment reported. Herein, we examined effects favipiravir (FPV) versus lopinavir (LPV)/ritonavir (RTV) for COVID-19. Patients with laboratory-confirmed COVID-19 who received oral FPV (Day 1: 1600 mg twice...

Severe coronavirus disease 2019 (COVID-19) is often indicated by lymphopenia and increased myelopoiesis; however, the underlying mechanism still unclear, especially alteration of hematopoiesis. It important to explore what extent how hematopoietic stem cells contribute impairment peripheral lymphoid myeloid compartments in COVID-19 patients. In this study, we used single-cell RNA sequencing assess bone marrow mononuclear from patients with blood as control. The results showed that these were...

The standard treatment for patients with chronic hepatitis C (CHC), pegylated interferon-α (PEG-IFN) plus ribavirin (RBV) does not provide a sustained virological response (SVR) in all patients. Genetic variations at the interleukin 28B (IL-28B) locus are important predicting outcome following therapy CHC patients.We investigated role of IL28B (rs8099917) to PEG-IFN-α/RBV and evaluated its association risk null (NVR) relapse (REL) different viral genotypes. We found that overall...
