Effects of Endoscopic Submucosal Excavation With Non-Submucosal Injection on Stromal Tumors in Stomach.

Background And Aim: Endoscopic submucosal excavation (ESE) is commonly used to treat gastrointestinal stromal tumors (GISTs), especially for tumor sizes within 2 cm; compared with the conventical ESE, the efficacy and safety of the no-submucosal injection (NSI) ESE remains unclear. The aim of this study was to assess the clinical efficacy and safety of NSI-ESE for gastric stromal tumors.

Methods: ESE was performed in 102 patients at our hospital between January 2018 and January 2020, and the clinical features, surgical outcomes, complications, cost of performance, pathological diagnosis, and risk classification were evaluated.

IRF1-mediated immune cell infiltration is associated with metastasis in colon adenocarcinoma.

Background: Evidence suggests that metastasis is chiefly responsible for the poor prognosis of colon adenocarcinoma (COAD). The tumor microenvironment plays a vital role in regulating this biological process. However, the mechanisms involved remain unclear.

Clinical Analysis of 161 Cases of Surgical Treatment of Infective Endocarditis.

To evaluate the diagnostic criteria, surgical indications, and prognostic factors in the surgical treatment of infective endocarditis (IE). A total of 161 cases of post-operative IE treated at our hospital from January 2007 to December 2016 were included. The IE was diagnosed by the modified Duke criteria.

[Primary experience of treating 23 lone atrial fibrillation patients with a completely thoracoscopic modified Maze procedure].

Objective: To evaluate the safety and feasibility of a completely thoracoscopic modified Maze procedure for treatment of patients with lone atrial fibrillation(AF).

Methods: From September 2010 to October 2011, completely thoracoscopic modified Maze procedure was performed in 23 patients with lone atrial fibrillation (14 paroxysmal AF and 9 persistent AF). All patients were either refractory or intolerant to antiarrhythmic drug therapy or already experienced unsuccessful catheter-based ablation.

Outcome of veno-arterial extracorporeal membrane oxygenation for patients undergoing valvular surgery.

Background: We evaluated retrospectively the early and midterm results of using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support in patients undergoing valvular surgery.

Methods: A total of 87 patients undergoing valvular surgery received VA-ECMO due to refractory postcardiotomy cardiogenic shock (PCS), who were eligible for inclusion were enrolled in this study. Preoperative, perioperative, and postoperative variables were assessed and analyzed for possible associations with mortality in hospital and after discharge.

A mortality risk assessment model for cardiac valve replacement surgery and its application in the use of prophylactic extracorporeal membrane oxygenation.

This study was conducted to establish a quantitative model to predict the risk of in-hospital mortality for patients undergoing cardiac valve replacement and to decrease mortality in patients with predicted high risk using prophylactic extracorporeal membrane oxygenation (PECMO). We retrospectively reviewed the medical records of 4482 patients who underwent cardiac valve replacement from January 1994 to December 2004, at Anzhen Hospital, Beijing, China. A total of 158 patients were going to receive heart valve replacement.

[Clinical experience with adults receiving extracorporeal membrane oxygenation for cardiogenic shock and quality of life in survivals].

Objective: To review the experience with extracorporeal membrane oxygenation (ECMO) in adult postcardiotomy cardiogenic shock and evaluate quality of life (QOL) in survivals.

Methods: During 4 years 62 of 12, 644 patients (0.49%) undergoing cardiac surgery (valve procedures, n = 39; coronary artery bypass grafting, n = 13; coronary artery bypass grafting plus valve procedures, n = 4; heart transplantation, n = 4, and total aortic arch replacement, n = 2) required temporary postoperative ECMO support.

Using intramyocardial electrograms combined with other noninvasive methods for monitoring acute rejection following human heart transplantation.

Background: Acute allograft rejection in heart transplantation remains as one of the major complications. Obligatory graft surveillance is still achieved with the invasive and expensive endomyocardial biopsy (EMB). Our study aimed to study the use of intramyocardial electrograms combined with other noninvasive methods for the monitoring of acute rejection after human heart transplantation.
