Decellularized tissue matrices hydrogels functionalized with extracellular vesicles promote macrophage reprogramming and neural stem cell differentiation for spinal cord injury repair.

This study investigates the application of decellularized tissue matrices (DSCM) hydrogels functionalized with extracellular vesicles (EVs) derived from mesenchymal stromal cells (MSCs) for spinal cord injury (SCI) treatment. The primary focus is on how these composites influence macrophage reprogramming and neural stem cell (NSC) differentiation by modulating Slamf9 expression. MSC-derived EVs were successfully isolated, and DSCM hydrogels were prepared from porcine spinal cords.

Examining cancer patient preferences during three stages of decision making and family involvement: a multicenter survey study in China.

Background: Medical decision-making is a complex multi-stage process. Chinese cancer patients' preference for participation in decision-making stages, family involvement and influencing factors remain unclear.

Methods: A total of 1,422 cancer patients from four tertiary hospitals in China were included in the cross-sectional survey.

Effectiveness and Safety of Acupuncture for the Treatment of Alzheimer's Disease: A Systematic Review and Meta-Analysis.

The effects of acupuncture on Alzheimer's disease (AD) outcomes remain controversial. The aim of this review was to evaluate the effectiveness and safety of acupuncture for the treatment of AD. PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, Chinese BioMedical Literature Database, VIP Database for Chinese Technical Periodicals, China National Knowledge Infrastructure, and Wanfang Data were searched to identify relevant randomized controlled trials from inception to January 19, 2019.

The methodology for developing nursing clinical practice guidelines over recent decades in China: A critical appraisal using AGREE II.

Aim: To appraise the quality of current nursing clinical practice guidelines (N-CPGs) in China and explore the methodology for N-CPGs development.

Background: Implementation of quality improvement projects based on N-CPGs has becoming an hot topic for nursing with proliferation in the number of N-CPGs in China in recent years. The methodology for developing N-CPGs is worthy of exploration.

A Better Way to Attend: Attention with Trees for Video Question Answering.

We propose a new attention model for video question answering. The main idea of the attention models is to locate on the most informative parts of the visual data. The attention mechanisms are quite popular these days.

Unifying the Video and Question Attentions for Open-Ended Video Question Answering.

Video question answering is an important task toward scene understanding and visual data retrieval. However, current visual question answering works mainly focus on a single static image, which is distinct from the dynamic and sequential visual data in the real world. Their approaches cannot utilize the temporal information in videos.

Depth Image Inpainting: Improving Low Rank Matrix Completion With Low Gradient Regularization.

We address the task of single depth image inpainting. Without the corresponding color images, previous or next frames, depth image inpainting is quite challenging. One natural solution is to regard the image as a matrix and adopt the low rank regularization just as color image inpainting.
