Association of Hypertension with Severity and Mortality in Hospitalized Patients with COVID-19 in Wuhan, China: A Single-centered, Retrospective Study.

Background: Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread worldwide.

Objective: To investigate the association between hypertension and severity/mortality in hospitalized patients with COVID-19 in Wuhan, China.

Methods: A total of 337 patients diagnosed with COVID-19 at the Seventh Hospital of Wuhan City, from January 20 to February 25, 2020, were enrolled and analyzed in a retrospective, single-center case study.

Association of diabetes with severity and mortality in hospitalized patients with COVID-19 in Wuhan, China: a single-centered, retrospective study.

Objective: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread worldwide. The aim this study was to investigate the association of diabetes with severity and mortality among hospitalized patients with COVID-19 in Wuhan, China.

Methods: This retrospective, single-center case study enrolled a total of 564 patients diagnosed with COVID-19 at the Seventh Hospital of Wuhan City, between January 20 and March 15, 2020.

Down-Regulation of miR-218-5p Promotes Apoptosis of Human Umbilical Vein Endothelial Cells Through Regulating High-Mobility Group Box-1 in Henoch-Schonlein Purpura.

Background: Apoptosis of human umbilical vein endothelial cells (HUVECs) plays an important role in the progression of Henoch-Schonlein purpura (HSP). In the present study, we explored the function of miR-218-5p in HUVEC apoptosis and HSP development.

Materials And Methods: HSP rat model was established and peripheral blood mononuclear cells (PBMC) were isolated.

Effect of annealing treatment on electroluminescence from GaN/Si nanoheterostructure array.

A GaN/Si nanoheterostructure array was prepared by growing GaN nanostructures on silicon nanoporous pillar array (Si-NPA). Based on as-grown and annealed GaN/Si-NPA, two light-emitting diodes (LEDs) were fabricated. It was found that after the annealing treatment, both the turn-on voltage and the leakage current density of the nanoheterostructure varied greatly, together with the electroluminescence (EL) changed from a yellow band to a near infrared band.
