Early postoperative constrictive pericarditis in China: a single-center retrospective observational study.

Background: The diagnosis, treatment, and prognosis of early postoperative constrictive pericarditis (EPCP) have not been discussed in depth. The objective of this study was to devise and propose a management strategy for EPCP.

Methods: In this study, constrictive pericarditis (CP) within 6 months after cardiac surgery was defined as EPCP, and patients were divided into two groups based on intraoperative findings: a parietal thickening group and a visceral thickening group.

Intracardiac paraganglioma with a cough as the first symptom.

Background: Cardiac paragangliomas (PGLs) are clinically rare, with hypertension and metabolic changes as the main symptoms. The tumor is highly related to gene mutation, and surgery is presently the effective treatment. Medical history and clinical manifestations of the patient, routine laboratory examinations and imaging examinations, and pathological examination can help the final diagnosis.

Preoperative 6-minute walk test predicts prolonged hospitalization after transcatheter tricuspid valve replacement.

The purpose of this study is to determine whether preoperative 6-minute walk test (6MWT) is associated with prolonged postoperative hospitalization in high risk patients with severe tricuspid regurgitation (TR) after transcatheter tricuspid valve replacement (TTVR). Forty-one patients with severe TR who underwent TTVR and discharged between September 2018 and April 2021 were enrolled in this study. Patients were divided into 2 groups according to whether the postoperative hospital stay was >10 days and patients' data were retrospectively collected.

Impact of transcatheter tricuspid valve replacement for tricuspid regurgitation on hepatic, cardiac, and venous structure.

Background: Patients with long-term tricuspid regurgitation (TR) are mostly accompanied by hepatic, cardiac, and venous remodeling. Transcatheter tricuspid valve replacement (TTVR) device has emerged as a promising alternative to open-heart surgery for TR patients. No study has assessed the impact of TTVR on hepatic, cardiac, and venous remodeling.

Hemodynamics of transcatheter tricuspid valve replacement with Lux-Valve.

Objective: Transcatheter tricuspid valve intervention (TTVI) has emerged as an alternative treatment option for high-risk and inoperable patients with symptomatic tricuspid regurgitation (TR). However, scarce data in hemodynamic profiles were available on TTVI. In this paper, we attempt to report the hemodynamic profiles of LuX-Valve.

miR-129-2 upregulation induces apoptosis and promotes NSCLC chemosensitivity by targeting SOX4.

Background: As one of the main causes of death worldwide, the treatment of non-small-cell lung cancer (NSCLC) is still unsatisfactory. This study aimed to explore the role of miR-129-2 in cell apoptosis and NSCLC chemosensitivity.

Methods: The effect of miR-129-2 on NSCLC was investigated using lung cancer cell lines (A549, NCl-H23, and HCC827), a normal lung cell line (BEAS-2B), and NSCLC tissues and adjacent healthy tissues.

Transcatheter tricuspid valve replacement in patients with severe tricuspid regurgitation.

Objective: Tricuspid regurgitation (TR) is a common valvular heart disease with unsatisfactory medical therapeutics and high surgical mortality. The present study aims to evaluate the safety and effectiveness of transcatheter tricuspid valve replacement (TTVR) in high-risk patients with severe TR.

Methods: This was a compassionate multicentre study.

HSF1 and NF-κB p65 participate in the process of exercise preconditioning attenuating pressure overload-induced pathological cardiac hypertrophy.

Pathological cardiac hypertrophy, often accompanied by hypertension, aortic stenosis and valvular defects, is typically associated with myocyte remodeling and cardiac dysfunction. Exercise preconditioning (EP) has been proven to enhance the tolerance of the myocardium to cardiac ischemia-reperfusion injury. However, the effects of EP in pathological cardiac hypertrophy are rarely reported.

Exercise preconditioning attenuates pressure overload-induced pathological cardiac hypertrophy.

Pathological cardiac hypertrophy, a common response of the heart to a variety of cardiovascular diseases, is typically associated with myocytes remodeling and fibrotic replacement, cardiac dysfunction. Exercise preconditioning (EP) increases the myocardial mechanical load and enhances tolerance of cardiac ischemia-reperfusion injury (IRI), however, is less reported in pathological cardiac hypertrophy. To determine the effect of EP in pathological cardiac hypertrophy, Male 10-wk-old Sprague-Dawley rats (n=30) were subjected to 4 weeks of EP followed by 4-8 weeks of pressure overload (transverse aortic constriction, TAC) to induce pathological remodeling.

Increased expression of chitinase 3-like 1 is a prognosis marker for non-small cell lung cancer correlated with tumor angiogenesis.

Increasing evidence demonstrated that chitinase 3-like 1 (CHI3L1) was highly expressed and tightly associated with human tumor development and progression. However, its precise role in non-small cell lung cancer (NSCLC) remains to be delineated. The aim of this study was to examine CHI3L1 expression in patients with NSCLC and explore the relationship of CHI3L1 protein with clinicopathologic factors, tumor angiogenesis, and prognosis.
