Diagnosis of primary meningeal natural killer/T‑cell lymphoma of the central nervous system using cerebrospinal fluid cytology: A case report.

Primary central nervous system (CNS) lymphoma of the meninges is a rare tumor that originates in the meninges and does not show parenchymal or systemic spread. CNS involvement by natural killer (NK)/T-cell lymphoma accounts for only 2% of all extranodal NK/T-cell lymphomas, and primary NK/T-cell lymphoma of the meninges is even rarer. The present study reports a case of a 55-year-old male patient with primary NK/T-cell lymphoma.

Meta-analysis of vitamin D supplementation in the treatment of chronic heart failure.

. We performed a meta-analysis to determine whether vitamin D supplementation is beneficial in patients with chronic heart failure (CHF). .

Factors Influencing Stent Restenosis After Percutaneous Coronary Intervention in Patients with Coronary Heart Disease: A Clinical Trial Based on 1-Year Follow-Up.

BACKGROUND This study observed the incidence of in-stent restenosis (ISR) after percutaneous coronary intervention (PCI) and discusses the risk factors of ISR based on clinical data, coronary angiography, and stent features, to provide a theoretical basis for the prevention and treatment of ISR. MATERIAL AND METHODS We selected 1132 cases who received stent implantation at the Shaanxi People's Hospital from June 2014 to June 2016 and were followed up by coronary angiography within 1 year. Based on coronary angiography, the cases were divided into ISR and non-ISR groups.

Complications of retrograde intrarenal surgery classified by the modified Clavien grading system.

The increase in the retrograde intrarenal surgery (RIRS) has been accompanied by the increase in complications. This study identified the factors that affected the severity of the complications using the modified Clavien classification system (MCCS). Three hundred and twenty-two consecutive RIRS performed by a single surgeon were analyzed.

The utility of diffusion MRI with quantitative ADC measurements for differentiating high-grade from low-grade cerebral gliomas: Evidence from a meta-analysis.

Objective: The aim of this meta-analysis was to predict the grades of cerebral gliomas using quantitative apparent diffusion coefficient (ADC) values.

Materials And Methods: A comprehensive search of the PubMed, EMBASE, Web of Science, and Cochrane Library databases was performed up to 8, 2016. The quality assessment of diagnostic accuracy studies (QUADAS 2) was used to evaluate the quality of studies.

Accuracy of combined dynamic contrast-enhanced magnetic resonance imaging and diffusion-weighted imaging for breast cancer detection: a meta-analysis.

Background: Magnetic resonance imaging (MRI) is increasingly being used to examine patients with suspected breast cancer.

Purpose: To determine the diagnostic performance of combined dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion-weighted imaging (DWI) for breast cancer detection.

Material And Methods: A comprehensive search of the PUBMED, EMBASE, Web of Science, and Cochrane Library databases was performed up to September 2014.
