Risk Factors and Prognosis in Patients with COVID-19 and Liver Injury: A Retrospective Analysis.

Purpose: COVID-19 is a new infectious disease with global spread. The aim of the present study was to explore possible risk factors and evaluate prognosis in COVID-19 with liver injury.

Methods: A retrospective study was conducted on 356 COVID-19 patients in the Third People's Hospital of Yichang, Hubei, China.

High serum lactate dehydrogenase and dyspnea: Positive predictors of adverse outcome in critical COVID-19 patients in Yichang.

Background: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in China, constitutes a Public Health Emergency of International Concern. It is well known that COVID-19 patients may have increased serum lactate dehydrogenase (LDH) levels in the early stage. The clinical changes in LDH may have predictive value in disease evolution and prognosis in critically ill COVID-19 patients.

The Significant Impact of Carbon Nanotubes on the Electrochemical Reactivity of Mg-Bearing Metallic Glasses with High Compressive Strength.

Here, we elucidate the significant impact of carbon nanotubes (CNTs) on the electrochemical behavior of Mg-based amorphous composite materials that were reinforced with CNTs while using pressure die casting. The addition of 3 vol % CNTs led to an increase in the compressive strength of Mg-based amorphous material from 812 MPa to 1007 MPa, and the fracture strain from 1.91% to 2.

[Influence of the escharectomy during stock stage on the peripheral lymphocyte apoptosis and the antigen presentation function of monocytes in peripheral blood of scalded rats].

Objective: To investigate the influence of escharectomy at different time-points after burn injury on the lymphocyte apoptosis and the antigen presentation function of monocytes in peripheral blood of scalded rats.

Methods: One hundred and thirty-six Wistar rats were randomly divided into normal control ( C,n = 8 ), scald ( S, n = 64,without treatment after scald) , A ( n = 40, with escharectomy at 36 post-burn hour( PSH) ) , B ( n = 24, with escharectomy at 72 PSH ) groups. The rats in A , B, S groups were inflicted with 30% TBSA full-thickness scald.
