Development and validation of a risk assessment model for predicting the failure of early medical abortions: A clinical prediction model study based on a systematic review and meta-analysis.

Objective: As the first model in predicting the failure of early medical abortion (EMA) was inefficient, this study aims to develop and validate a risk assessment model for predicting the failure of EMAs more accurately in a clinical setting.

Methods: The derivation cohort was obtained from a comprehensive systematic review and meta-analysis. The clinically significant risk factors were identified and combined with their corresponding odds ratios to establish a risk assessment model.

Long-term outcomes and independent predictors of mortality in patients presenting to emergency departments with acute heart failure in Beijing: a multicenter cohort study with a 5-year follow-up.

Background: Acute heart failure (AHF) is the most common disease in emergency departments (EDs). However, clinical data exploring the outcomes of patients presenting AHF in EDs are limited, especially the long-term outcomes. The purposes of this study were to describe the long-term outcomes of patients with AHF in the EDs and further analyze their prognostic factors.

Electrospinning fabrication for cloth-like carbon nanofiber films with hierarchical porous structure and their application in deep desulfurization.

A strategy for clean fuel by selective adsorption processing was deemed to be convenient and environmental-friendly in past decades. However, the development of adsorption desulfurization was tremendously subject to the fabrication of high-performance adsorbents with large capacity and high stability. Herein, we designed a novel route to fabricate the cloth-like carbon nanofiber film with a hierarchical porous structure by electrospinning.

Design and fabrication of in-situ N-doped paper-like carbon nanofiber film for thiophene removal from a liquid model fuel.

The novel nitrogen-doped porous carbon nanofibers film (PAN-CNFs) had been successfully prepared by electrospinning with polyacrylonitrile as carbon precursor after calcination under N atmosphere. The structure and physical properties of PAN-CNFs were determined by a series of characterizations. The results showed that the PAN-CNFs-800 have the higher N content (10.

Characteristics, Management, and Outcomes of Acute Heart Failure in the Emergency Department: A Multicenter Registry Study with 1-year Follow-up in a Chinese Cohort in Beijing.

Background: The emergency department (ED) has a pivotal influence on the management of acute heart failure (AHF), but data concerning current ED management are scarce. This Beijing AHF Registry Study investigated the characteristics, ED management, and short- and long-term clinical outcomes of AHF.

Methods: This prospective, multicenter, observational study consecutively enrolled 3335 AHF patients who visited 14 EDs in Beijing from January 1, 2011, to September 23, 2012.

Late onset radiation-induced constrictive pericarditis and cardiomyopathy after radiotherapy: A case report.

Introduction: Radiation-induced heart disease (RIHD) is a serious side effect of cancer treatment, including coronary artery disease, valvular cardiac dysfunction, cardiomyopathy, aortopathy, and chronic constrictive pericarditis. Herein, this case we present was diagnosed as radiation-induced constrictive pericarditis and cardiomyopathy by means of cardiac magnetic resonance (CMR) and transthoracic echocardiogram, finally confirmed by pathology after performing heart transplant operation.

Conclusions: This case supports a notion that RIHD often causes multiple heart impairment and CMR is helpful to diagnose cardiomyopathy after radiation.

Differential controls on soil carbon density and mineralization among contrasting forest types in a temperate forest ecosystem.

Understanding the controls on soil carbon dynamics is crucial for modeling responses of ecosystem carbon balance to global change, yet few studies provide explicit knowledge on the direct and indirect effects of forest stands on soil carbon via microbial processes. We investigated tree species, soil, and site factors in relation to soil carbon density and mineralization in a temperate forest of central China. We found that soil microbial biomass and community structure, extracellular enzyme activities, and most of the site factors studied varied significantly across contrasting forest types, and that the associations between activities of soil extracellular enzymes and microbial community structure appeared to be weak and inconsistent across forest types, implicating complex mechanisms in the microbial regulation of soil carbon metabolism in relation to tree species.

Soil microbial responses to forest floor litter manipulation and nitrogen addition in a mixed-wood forest of northern China.

Changes in litterfall dynamics and soil properties due to anthropogenic or natural perturbations have important implications to soil carbon (C) and nutrient cycling via microbial pathway. Here we determine soil microbial responses to contrasting types of litter inputs (leaf vs. fine woody litter) and nitrogen (N) deposition by conducting a multi-year litter manipulation and N addition experiment in a mixed-wood forest.

Ion pair charge-transfer thiogermanate salts [MV]2Ge4S10·xSol: solvent induced crystal transformation and photocurrent responsive properties.

As most of the chalcogenidometalate anions are well-known electron-rich systems, design and preparation of ion pair compounds, by integrating an organic acceptor (A) with an inorganic chalcogenidometalate donor (D), are an attractive strategy to obtain new functional materials. We report herein the single-crystal structures and properties of three new ion pair charge-transfer (IPCT) compounds by incorporating thiogermanates with methylviologen (MV(2+), N,N'-dimethyl-4,4'-bipyridinium dication), [MV]2Ge4S10·xSol (Sol = solvent). Sharp and fast solvent-induced color changes and switchable fluorescence emission are observed for the compounds.

[Clinical characteristics of 22 cases of fungal infective endocarditis].

Objective: To explore the clinical characteristics, treatment regimens and outcomes of the patients with fungal infective endocarditis.

Methods: An observational study was conducted at our hospital and recruited 22 consecutive patients with a definite diagnosis of fungal infective endocarditis. Their overall characteristics, treatments, complications and outcomes were analyzed.

Comparison of characteristics and short-term outcome from fungal infective endocarditis in prosthetic valve endocarditis versus native valve endocarditis.

Fungal infective endocarditis (IE) is a rare, serious, and potentially lethal disease, yet its clinical characteristics and short-term outcomes remain poorly understood. A detailed comparative analysis of fungal prosthetic valve endocarditis (PVE) and native valve endocarditis (NVE) has not been performed. This study was designed to explore the general characteristics, treatment patterns, and outcomes of patients with fungal IE in a Chinese hospital and compare these data between PVE and NVE.

Methods: SCs were cultured in vitro and a compound graft was prepared from the SCs and SIS. Thirty-three healthy SD rats were randomly divided into three groups of equal number, sham-operation, CN ablation, and SIS + SC graft.

Atorvastatin attenuates Coxsackie virus B3m-induced viral myocarditis in mice.

In the present study, we determined the therapeutic efficacy of atorvastatin on Coxsackievirus B3m (CVB3m)-induced myocarditis. Mice were administered Eagle minimal essential medium, virus solution, atorvastatin, or virus plus atorvastatin. Atorvastatin was given 3 days after viral challenge, and the treatment lasted for 14 days.

Cardioprotective actions of an N-terminal fragment of annexin-1 in rat myocardium in vitro.

We have previously shown that the glucocorticoid dexamethasone prevents the cardiodepressant actions of interferon-gamma plus lipopolysaccharide in cardiac tissue in vitro. We now demonstrate that an N-terminal fragment of annexin-1 (Ac2-26, 1 microM), a putative mediator of glucocorticoid actions, completely protects against interferon-gamma+lipopolysaccharide-induced depression of the inotropic response to isoprenaline in rat isolated papillary muscles. However, Ac2-26 does not preserve resting contractile function.
