Background: The CRC-VTE trial conducted in China revealed a significant occurrence of venous thromboembolism (VTE) in patients following colorectal cancer (CRC) surgery, raising concerns about implementing thromboprophylaxis measures. The present study aimed to identify and analyze inappropriate aspects of current thromboprophylaxis practices.

Methods: This study performed an analysis of the CRC-VTE trial, a prospective multicenter study that enrolled 1836 patients who underwent CRC surgery.

Background: Venous thromboembolism (VTE) is a common and serious complication after colorectal cancer (CRC) surgery. Few large-sample studies have reported VTE incidence and management status after CRC surgery in China. This study aimed to investigate the incidence and prevention of VTE in Chinese patients after CRC surgery, identify risk factors for developing VTE, and construct a new scoring system for clinical decision-making and care planning.

Background: Patients with atrial fibrillation (AF) and coronary stenting had a poor prognosis. This study aimed to assess the accuracy of CHA2DS2-VASc score for predicting and grading adverse clinical outcomes in this population.

Methods: We reviewed the clinical data of all patients with previously documented nonvalvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China.

The aim of this study was to evaluate the effectiveness and safety of AngioJet rheolytic thrombectomy among patients with high thrombus burden. Routine manual thrombus aspiration in patients with ST-segment elevation myocardial infarction (STEMI) does not improve clinical outcomes and was associated with an increased rate of stroke. However, the safety of mechanical thrombus aspiration is still unknown.

Objective: This study aimed to evaluate predictors for adverse cardiovascular outcomes in patients with atrial fibrillation (AF) undergoing coronary stenting.

Methods: We retrospectively recruited consecutive patients with previously documented non-valvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China. Major adverse cardiac/cerebrovascular events (MACCE) were a composite of all-cause death, non-fatal myocardial infarction, repeat revascularization, and ischaemic stroke/systemic thromboembolism (IS/STE).

Objective: Sex differences in the clinical outcomes of patients with atrial fibrillation (AF) and coronary stenting should be assessed according to age.

Methods: We analyzed the clinical data of all patients with nonvalvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China.

Results: A total of 2,146 patients (71.

Background: Venous thromboembolism is a common vascular syndrome presenting as deep vein thrombosis and/or pulmonary embolism. Thrombus has the possibility of migrating into the left circulation patent foramen ovale in certain extreme circumstances. Thrombus straddling a patent foramen ovale is a direct evidence of this scenario.

Background: To analyze the cardio-protective effects of ticagrelor in patients with acute coronary syndrome with S-T segment elevation.

Methods: The sample was 200 patients who had been diagnosed with acute coronary syndrome accompanied by diabetes Mellitus type II. Only patients having ST segment elevation before the treatment were included.

Pichia pastoris expression is a mature and efficient eukaryotic expression system. In this work, Aspergillus oryzae lipase (AOL, with the molecular mass of 28 kDa), which can perform highly stereoselective hydrolysis of (R, S)-methyl 2-(4-hydroxyphenoxy) propanoate, was expressed in P. pastoris X-33.

Background: The prevalence of CHD has been well described worldwide except in Tibet. This study aimed to illustrate the prevalence and composition of CHD in Tibetan children according to altitude. Methods and results In the first part, we prospectively recruited 7088 unselected Tibetan children (4-17 years) from south-west Tibet.

To evaluate the utility of transthoracic contrast echocardiography (cTTE) using vitamin B6 and sodium bicarbonate as contrast agents for diagnosing right-to-left shunt (RLS) caused by patent foramen ovale (PFO) compared to that of transesophageal echocardiography (TEE). We investigated 125 patients admitted to our neurology department with unexplained cerebral infarction and migraine. All patients underwent cTTE using vitamin B6 and sodium bicarbonate as contrast agents, after which they underwent transthoracic echocardiography.

Background: Phytohormones are chemical messengers that have a positive effect on biodiesel production of microalgae at low concentrations. However, the effect of phytohormone 6-benzylaminopurine on lipid and docosahexaenoic acid (DHA) production in marine DHA-producer Aurantiochytrium has never been reported. In this study, a GC-MS-based metabolomics method combined with a multivariate analysis is applied to reveal the metabolic mechanism of 6-benzylaminopurine enhancing production of lipid and DHA in Aurantiochytrium sp.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a congenital heart defect rarely diagnosed beyond infancy. We present a 9-year-old girl who had once been diagnosed as congenital coronary artery fistula. Echogenic mitral chordae tendineae, multiple coronary collaterals within the ventricular septum and free ventricular wall, and a shunting flow from the left coronary artery into the pulmonary artery were prominent echocardiographic features of ALCAPA.

Article Synopsis
  • The study aimed to evaluate the prevalence of decreased glomerular filtration rate (GFR) in Tibetan children with congenital heart disease (CHD) and identify risk factors associated with it.
  • Out of 207 Tibetan children studied, 10.1% had decreased GFR, with significant findings that severely cyanotic children and those with greater left ventricular internal dimensions were more affected.
  • Key risk factors for decreased GFR included being younger, living at high altitudes (above 4,700 m), and having increased left ventricular dimensions, with LVID/BSA identified as a strong predictor for low GFR levels.

Objective: To understand the incidence of acute kidney injury (AKI) in infants and toddlers and evaluate the possibility of predicting AKI with urine neutrophil gelatinase-associated lipocalin (NGAL), interleukin 18 (IL-18), N-acetyl-beta-D-glucosaminidase (NAG), microalbumin (MA) and α1-microglobulin (α1-MG) after surgeries for congenital heart diseases with cardiopulmonary bypass (CPB).

Method: Fifty-eight children (ages ≤ 3 years) who had undergone surgery for congenital heart diseases with CPB were enrolled. Urinary samples were collected before and 4 h, 6 h, 12 h, 24 h post CPB to detect the concentration of NGAL, IL-18, NAG, MA and α1-MG.
