Recently, virtual staining techniques have attracted more and more attention, which can help bypass the chemical staining process of traditional histopathological examination, saving time and resources. Meanwhile, as an emerging tool to characterize specific tissue structures in a label-free manner, the Mueller matrix microscopy can supplement more structural information that may not be apparent in bright-field images. In this Letter, we propose the Mueller matrix guided generative adversarial networks (MMG-GAN).

Within the Poincaré sphere system, this study achieves a spatial representation of the Mueller matrix: the Global-Polarization Stokes Ellipsoid (GPSE). With the help of Monte Carlo simulations combined with anisotropic tissue models, three basic characteristic parameters of GPSE are proposed and explained, where the V parameter represents polarization maintenance ability, and the E and D parameters represent the degree of anisotropy.

In this study, recurrent implantation failure (RIF)-related GSE58144 dataset was extracted from the Gene Expression Omnibus (GEO) database. Firstly, the immune micro-environment analyses were conducted to analyze the pathogenesis of KIR2DL4 in RIF.

Material And Methods: Real-time PCR was performed to compare the levels of irisin, blood glucose, UCA1 and miR-18a among PCOS, PCOS + Met, and control groups using area under curve (AUC) values. In-silicon analysis and luciferase assay were performed to explore the regulatory relationship among UCA1, miR-18a and irisin.
Dexmedetomidine and propofol are commonly used sedative agents in pediatric patients undergoing magnetic resonance imaging (MRI). The present meta-analysis aimed to compare dexmedetomidine with propofol in pediatric patients undergoing MRI using trial sequential analysis (TSA). The PubMed, Cochrane Library and Web of Knowledge databases were systematically searched for entries up to August 2018 for potential randomized controlled trials comparing dexmedetomidine with propofol in pediatric patients undergoing MRI.

But it is usually hard to acquire high-quality images, for the uncooperative ability of children. It is believed that pre-MRI training could ensure the high quality of images.

A total of 374 child patients diagnosed with NB via CT scan and pathological section in Department of Pediatric of Xuzhou Children's Hospital from March 2011 to January 2017 were collected, and their clinical data were retrospectively analyzed. According to CT signs, NB calcification and invasion to surrounding tissues were evaluated, and the tumor site, tumor size, lymphatic metastasis, pathological types and clinical prognosis were analyzed.

Methods: The clinical data of 100 HIE children, who were admitted to the Department of Radiology, Xuzhou Children's Hospital, Jiangsu, from June 2013 to June 2014, were statistically analyzed.
Results: Among the imaging data of 100 HIE children, the detection rate and false negative rate were 91.
Objective: To explore the experimental basis of the "water metabolism theory" in traditional Chinese medicine by observing the changes of aquaporin-1 in the lung, spleen and kidney.
Methods: Rat models of Kidney Yang Deficiency induced by gavage with 2% adenine suspension for 4 weeks were treated with cistanches decoction for 6 weeks. Urinary 17-hydroxy cortisol, urine creatinine, urine osmolality value content, and aquaporin-1 mRNA and protein expressions in the lung, spleen and kidney tissues were detected after the treatment.
