Therapeutic Efficacy of a Staged Hybrid Technique vs. Coronary Artery Bypass Surgery Grafting in The Treatment of Multi-Vessel Coronary Artery Disease.

Objective: Hybrid coronary revascularization (HCR) integrates the advantages of coronary artery bypass surgery grafting (CABG) and percutaneous coronary intervention (PCI) and provides another effective treatment for multi-vessel coronary artery disease (CAD). This study aimed to investigate the short- and intermediate-term efficacies of a staged hybrid technique vs. CABG in treating older patients with multi-vessel CAD.

The risk of missed abortion associated with the levels of tobacco, heavy metals and phthalate in hair of pregnant woman: A case control study in Chinese women.

To assess the association between exposure to the tobacco, heavy metals and phthalate on early pregnancy and missed abortion.42 women with missed abortion and 57 matched controls (women with normal pregnancies) were recruited between March and May 2012, from the Department of Gynecology and Obstetrics, First Affiliated Hospital of Guangxi Medical University and the People Hospital of Guangxi Zhuang Autonomous Region. The questionnaire survey was carried on to learn about the basic conditions, as well as smoking history of all participants.

Chronic exposure to manganese sulfate leads to adverse dose-dependent effects on the neurobehavioral ability of rats.

Manganese sulfate is the main combustion product of methylcyclopentadienyl manganese tricarbonyl (MMT). Currently, little is known about the neurobehavioral consequences of chronic manganese sulfate exposure. In this study, rats were treated with 0, 5.

Increased oxidative stress and plasma Hsp70 levels among gasoline filling station attendants.

Objectives: Methylcyclopentadienyl manganese tricarbonyl (MMT) is an organic derivative of manganese (Mn) and is used as an antiknock agent and octane enhancer in gasoline. In this article, we tested the oxidative stress and heat stress protein (Hsp) 70 levels of gasoline station attendants to explore potential plasma biomarkers. Furthermore, the dose-response relationship was also identified.

Elevated serum complement factors 3 and 4 are strong inflammatory markers of the metabolic syndrome development: a longitudinal cohort study.

An epidemiological design, consisting of cross-sectional (n = 2376) and cohort (n = 976) studies, was adopted to investigate the association between complement factors 3 (C3) and 4, and the metabolic syndrome (MetS) development. In the cross-sectional study, the C3 and C4 concentrations in the MetS group were higher than those in the non-MetS group (all P < 0.001), and the levels of immune globulin M (IgM), IgA, IgE, and IgG exhibited no significant differences between MetS and non-MetS (all P > 0.

[Effects of chronic manganese sulfate toxicity test on myocardial ultrastructure and heart organ index of rats].

Objective: To observe the effects of manganese sulfate on blood pressure, myocardial ultrastructure and heart organ index of rats.

Methods: Forty male SPF SD rats were randomly divided into 4 groups: control group (0 mg/kg), 5 mg/kg dose group, 15 mg/kg dose group and 25 mg/kg dose group, 10 rats each group. Intraperitoneal injection was performed for six months, by five times each week, the rat blood pressure was measured by tail cuff method, and the heart organ index of the rats was computed.

Association of atrial fibrillation with gene polymorphisms of connexin 40 and angiotensin II receptor type 1 in Chongming adults of Shanghai.

Objective: To characterized the gene polymorphisms of connexin 40 (cx40) and angiotensin II receptor type 1 (AT1R) in Chongming adults with atrial fibrillation (AF) and to explore their relationships with AF.

Methods: 82 patients with AF, and 82 subjects without AF were enrolled. Polymorphisms of cx40 G-44A and AT1 A1166C were detected.

Expression profile analysis of circulating microRNAs and their effects on ion channels in Chinese atrial fibrillation patients.

Objective: To investigate the changes in expression profile of circulating microRNAs (miRNAs) and the regulatory effect of atrial fibrilation (AF)-related miRNAs on ion channels.

Methods: 112 patients with AF were assigned into observation group, and another 112 non-AF people were assigned into control group. Total plasma RNAs were extracted from patients' blood samples.

Synergistic impaired effect between smoking and manganese dust exposure on pulmonary ventilation function in Guangxi manganese-exposed workers healthy cohort (GXMEWHC).

Purpose: The aims of this study were to investigate the effects of manganese (Mn) dust exposure on lung functions and evaluate the potential synergistic effect between smoking and Mn dust exposure among refinery workers.

Methods: A retrospective study including 1658 workers in a ferromanganese refinery was conducted, with subjects who were from the Guangxi manganese-exposed workers healthy cohort (GXMEWHC). Based on the Mn manganese cumulative exposure index (Mn-CEI), all subjects were divided into the low exposure group (n = 682) and the high exposure group (n = 976).

Rationale, design and baseline results of the Guangxi manganese-exposed workers healthy cohort (GXMEWHC) study.

Objective: To determine the relationship between biomarkers of exposure, disease and susceptibility, and early health effects and long-term diseases related to occupational manganese (Mn) exposure.

Design: Baseline survey of a longitudinal cohort study of workers in a ferromanganese refinery.

Participants: A total of 1888 individuals (1197 men, 691 women; average seniority 15.

Relationship of osteopontin and renal function with severity of coronary artery lesions.

Aim: To explore the relationship of plasma osteopontin (OPN) level and renal function with severity of coronary artery lesions.

Methods: OPN level and renal function were detected and compared in 210 patients with coronary heart disease (CHD group) and 134 patients without coronary heart disease (control group) to analyze the relationship of osteopontin and renal function with severity of coronary artery lesions.

Use of an artificial neural network to localize accessory pathways of Wolff-Parkinson-White syndrome with 12-lead electrocardiogram.

Today, radio-frequency ablation has been shown to be a safe and effective method to treat paroxysmal tachycardia with Wolff-Parkinson-White syndrome. The many criteria reported for localizing the sites of accessory pathways from a 12-lead electrocardiogram have not proven adequate to differentiate the correct sites of accessory pathways for all situations. This study trained an artificial neural network to differentiate the varied features needed to localize 10 sites of accessory pathways.

A telemedicine system for collaborative work on radiographic coronary video-images.
