[Correlation of dietary patterns and cognitive function among preschool children in Ma'anshan City in 2014-2015].

Objective: To classify the dietary patterns in preschoolers and explore the correlation between dietary patterns and executive functions.

Methods: Between April 2014 and June 2015, 12363 preschoolers were selected from 91 kindergartens of Ma 'anshan City. The classification of dietary patterns and executive functions by Brief-P were evaluated.

Vitamin D and risk of preterm birth: Up-to-date meta-analysis of randomized controlled trials and observational studies.

Aim: We performed a meta-analysis of randomized controlled trials (RCT) and observational studies to answer the two following questions: (i) whether low maternal circulating 25 hydroxyvitamin D (25-OHD) is associated with an increased risk of preterm birth (PTB) or spontaneous PTB (sPTB); and (ii) whether vitamin D supplementation alone during pregnancy can reduce the risk of PTB.

Methods: Literature search was carried out using Pubmed, Web of Science and Embase databases up to June 2016. Pooled OR or relative risk (RR) with 95%CI were computed using fixed or random effects models depending on the size of heterogeneity.

Workstation scheme and implementation for a medical imaging information system.

Objective: To discuss the scheme and implementation of workstation configuration for medical imaging information systems suitable to the practical situation in China.

Methods: The workstations were logically divided into picture archiving and communication system (PACS) workstations and radiology information system (RIS) workstations. The former applied to three kinds of diagnostic practice: the small matrix images, large matrix images and high resolution grayscale display applications.
