Rutin is a flavanol-type polyphenol that consists of flavanol quercetin and the disaccharide rutinose, which has been reported to exert various biological effects such as antioxidant anti-inflammatory activities. It not clear whether rutin protective effect on sepsis-induced cardiomyopathy (SIC). In this study, we used male C57BL/6 mice cecal ligation puncture (CLP) surgery establish model SIC. was precautionarily treated (50, 100, 200 mg/kg per day, 7 days) before CLP. The results showed...

Aim: Sepsis is an extremely complex, threatening and difficult-to-treat disease, which can occur at any age under underlying disease. RNF20 regulate NF-kappaB (NF-κB) signaling pathway the transcription of inflammatory factors target genes. Therefore, it great significance to study function in clinical treatment sepsis its mechanisms.Methods: C57BL/6 mice were subjected cecal ligation puncture (CLP) surgery. THP-1 cells induced with Lipopolysaccharide for 4 h.Results: gene, mRNA expression...

Sepsis is a fatal systemic inflammatory disease that causes septic acute kidney injury (AKI). In this work, we explored the roles of circ_0040994 in lipopolysaccharide (LPS)-induced human kidney-2 (HK2) cell injury.Circ_0040994, miR-17-5p and transient receptor potential melastatin 7 (TRPM7) expression were detected by qRT-PCR. Cell functions examined MTT assay, flow cytometry western blot, ELISA oxidative stress assay. The molecular association was dual-luciferase reporter...

Do-not-attempt-resuscitation (DNAR) orders are designed to allow patients opt out of receiving cardiopulmonary resuscitation in the event a cardiac arrest. While DNAR has become standard component medical care, there is limited research available specifically focusing on context emergency departments China. This study aimed fill that gap by examining factors related among department general tertiary teaching hospital Retrospective observational study. Emergency department. and analysis adult...

BACKGROUND:Lupus erythematosus (LE) is mainly clinically divided into cutaneous lupus (CLE) and systemic (SLE) depending on the presence of multi-system manifestations. The most common subtype CLE discoid (DLE). Graves’ disease (GD) immunologically characterized by lymphocytic infiltration thyroid gland thyroid-stimulating hormone (TSH) receptor antibodies (TSH-R-Ab), autoimmune pathogenic cause hyperthyroidism. Autoimmune dysfunction has been widely described in association with rheumatic...
