Conditional survival probability of distant-metastatic hepatocellular carcinoma: A population-based study.

Background: The prognosis of many patients with distant metastatic hepatocellular carcinoma (HCC) improved after they survived for several months. Compared with traditional survival analysis, conditional survival (CS) which takes into account changes in survival risk could be used to describe dynamic survival probabilities.

Aim: To evaluate CS of distant metastatic HCC patients.

Initial studies on the implanting sites of high and low ventricular septa using leadless cardiac pacemakers.

Objective: To study the safety and electrical characteristics of various implanting sites of the Micra pacemaker.

Method: A total of 15 patients from Beijing Anzhen Hospital, Capital Medical University, were included, who were implanted with Micra leadless pacemakers and allocated to either the high ventricular septum group (eight patients) or the low ventricular septum group (seven patients) based on their individual patient factors and clinical conditions. The baseline of the patients, the implanting area, the electrocardiogram change after implantation, the implantation data, the threshold, R wave, impedance, and the date of the 1-month follow-up were then analyzed.

Congenitally corrected transposition of the great arteries and implantation of a leadless pacemaker: a case report.

Background: Congenitally corrected transposition of the great arteries (ccTGA) is a rare cardiac anomaly and can lead to abnormal electrical activity of the heart. The implant of a pacemaker in such patients is more complicated than conventional operations. This case report of an adult with ccTGA who had a leadless pacemaker implant will provide a reference for diagnosing and treating such patients.

CHA2DS2-VASc score as a prognostic indicator in patients with atrial fibrillation undergoing coronary stenting.

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.

Predictive models for adverse clinical outcomes in Chinese patients with atrial fibrillation undergoing percutaneous coronary intervention with stenting.

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).

Sex difference in clinical outcomes of Chinese patients with atrial fibrillation and coronary stenting according to age.

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.

Inversion of PM2.5 atmospheric refractivity profile based on AlexNet model from the perspective of electromagnetic wave propagation.

Human civilization has reached an unprecedented height, but the industrialization of economic development also brings global warming, ozone depletion, acid rain, fresh water resources crisis, energy shortage, and environmental problems. In autumn and winter, haze becomes the usual state in the modern society, and PM2.5 has been becoming an important form of air pollution.

Initial experience with ablation of the innervation surrounding sinus and atrioventricular nodes to treat paroxysmal bradyarrhythmia.

Background: The symptomatic bradyarrhythmia is Class I indication for pacing therapy which is not a radical cure. The present study aimed to assess the feasibility and to present the initial results of the restricted ablation of the parasympathetic innervation surrounding sinus and atrioventricular (AV) nodes for treating patients with bradyarrhythmia.

Methods: A total of 13 patients with cardiogenic syncope were included from May 2008 to June 2015.

Attenuated plaque is associated with plaque prolapse accompanied by cardiac enzyme elevation after drug-eluting stent implantation.

Objectives: This study aimed to evaluate the relationship between grayscale intravascular ultrasound-attenuated plaque (AP) and poststenting plaque prolapse (PP) as well as their influence on creatine kinase-myocardial band (CK-MB) elevation after drug-eluting stent (DES) implantation.

Background: The relationship between baseline AP and poststenting PP and their impacts on percutaneous coronary intervention (PCI) are not well known.

Patients And Methods: A total of 141 single, native, de-novo coronary lesions in 141 patients with normal pre-PCI CK-MB levels who underwent intravascular ultrasound before and after DES implantation were studied.

Ultrasonic destruction of albumin microbubbles enhances gene transfection and expression in cardiac myocytes.

Background: It has been proven that ultrasonic destruction of microbubbles can enhance gene transfection efficiency into the noncardiac cells, but there are few reports about cardiac myocytes. Moreover, the exact mechanisms are not yet clear; whether the characteristic of microbubbles can affect the gene transfection efficiency or not is still controversial. This study was designed to investigate whether the ultrasound destruction of gene-loaded microbubbles could enhance the plasmids carried reporter gene transfection in primary cultured myocardial cell, and evaluate the effects of microbubbles characteristics on the transgene expression in cardiac myocytes.

[Phospholamban antisense RNA transfer attenuates post-infarction remodeling and preserves cardiac functions].

Objective: To investigate whether the gene transfer of phospholamban antisense RNA could inhibit remodeling and preserve cardiac function after myocardial infarction.

Methods: Wistar rats received a ligation of left coronary with a direct intramyocardial injection of phospholamban antisense RNA eukaryote vector PcDNA4-asPLB. The cardiac function, hemodynamics and ventricular geometry of three groups (shame, saline injection and PcDNA4-asPLB injection) were studied by echocardiography and left ventricle hemodynamic recording.

[Polymorphic Hind III restriction site of the Y chromosome and essential hypertension in Chinese Han People].

Objective: To examine whether there is an association essential hypertension pressure and a polymorphic Hind III biallelic marker in the non-recombining region of Y chromosome in Chinese Han people.

Methods: Peripheral blood samples were collected from 402 males with essential hypertension pressure and 455 age- and body height-matched healthy males as control group. Genomic DNA was extracted from the white blood cells.

[Efficacy and safety of the coronary intervention therapy to prevent electrical storm in patients with coronary artery disease but without myocardial infarction].

Objective: To study the efficacy and safety of the coronary interventional therapy to prevent electrical storm (ES) in patients with coronary artery diseases (CAD) but without myocardial infarction or ischemic cardiomyopathy.

Methods: Coronary angiography and stent implantation were performed in CAD patients with ES as major symptom, according to the standardized methods. Holter Electrocardiography was recorded regularly during follow-up.
