The association between ulcerative colitis and COVID-19 severity: a systematic review and meta-analysis systematic review.

Purpose: After the COVID-19 pandemic, many challenges arose regarding the impact of this disease on people with ulcerative colitis. The aims of this study were to estimate the prevalence, severity, and death consequences of COVID-19 in patients with ulcerative colitis using a systematic review and meta-analysis.

Methods: This study was conducted using a systematic review and meta-analysis method in the field of prevalence, severity, and clinical consequences of COVID-19 in people with ulcerative colitis worldwide.

polymorphism and its expression associated with ischemic stroke in Chinese population.

Background: Excision repair cross-complementing group 1 () was considered a potential candidate gene for ischemic stroke, and its polymorphisms might be associated with the susceptibility to ischemic stroke.

Methods: A total of 513 patients with ischemic stroke and 550 control subjects were recruited. The expression levels of messenger RNA (mRNA) in peripheral blood mononuclear cells and its protein in plasma were detected by quantitative real-time PCR () and enzyme-linked immunosorbent assay (), respectively.

Identification and Verification of Potential Hub Genes in Amphetamine-Type Stimulant (ATS) and Opioid Dependence by Bioinformatic Analysis.

: Amphetamine-type stimulant (ATS) and opioid dependencies are chronic inflammatory diseases with similar symptoms and common genomics. However, their coexpressive genes have not been thoroughly investigated. We aimed to identify and verify the coexpressive hub genes and pathway involved in the pathogenesis of ATS and opioid dependencies.

Study on Risk Factors for Death from Cardiomyopathy and Effectiveness of Health Information Management.

Objective: To explore risk factors for death from cardiomyopathy and the effectiveness of health information management (HIM).

Methods: A total of 80 patients with cardiomyopathy admitted in ICU of our hospital (January 2016-January 2020) were selected as study subjects, and the clinical data of the patients were retrospectively analyzed. The patients were divided into the survival group ( = 72) and the death group ( = 14) according to the treatment outcome.

Anti-Arrhythmic Effects of Linalool Cx43 Expression in a Rat Model of Myocardial Infarction.

Background: Lavender is a traditional therapy for different heart symptoms including palpitation, which comprises an important symptom of cardiac arrhythmias. This experiment was designed to evaluate the antiarrhythmic effects of linalool using an experimental model of arrhythmia following myocardial infarction in rats. The underlying electrophysiological mechanism through cardiac connexin 43 (Cx43) expression was also investigated.

Focusing of intense and divergent ion beams in a magnetic mass analyzer.

A magnetic mass analyzer is used to determine the beam composition of a vacuum arc ion source. In the analyzer, we used the concentric multi-ring electrodes to focus the intense and divergent ion beams. We describe the principle, design, and the test results of the focusing device.
