Influence of Taijiquan Exercise on Mentality and Emotion Regulation by Intelligent Medical Big Data Analysis

Taijiquan training emphasizes the relaxation of the mind and the body, pay attention to maintain the peace of mind, and minimize the impact of external interference on the body so as to make the mind more comfortable. This study mainly explores the influence of Taijiquan practice on emotion regulation based on intelligent medical health big data analysis. The significance of Taijiquan in developing and improving the positive emotions of middle-aged people and maintaining physical and mental health is expounded. There are two methods of data collection: full collection and incremental collection. In this study, when the psychological testing equipment was launched, a full amount of historical data was collected; after the psychological testing equipment was online, the collection method was generally carried out in the way of incremental collection. The subjects exercised Taijiquan three times a week, one hour each time, and the exercise content was the 24-style Taijiquan designated by the workstation. At the same time, the subjects were asked not to engage in other regular physical exercise projects in their spare time. By longitudinal tracking and comparison of the Taijiquan intervention group after participating in the Taijiquan exercise intervention, the differences in the state of mind and emotion regulation strategies, and 12 subjects were selected voluntarily to participate in the emotional Stroop (the color words used in the classic Stroop paradigm were replaced with emotional and nonemotional words written in different colors, and the subjects were still tasked with responding to colors) experimental paradigm. In this paper, the moderate-intensity Taijiquan project is selected, which is in line with the effective value threshold theory of exercise load. It studies the effects of exercise on the body shape, cardiopulmonary function, flexibility, and balance ability of the body according to the metabolism theory and the movement balance theory of the human body adapting to the environment. Before the experiment, there was no significant difference between the Taijiquan training group and the control group, but after the experiment, there was a significant difference between the Taijiquan training group and the control group (P<0.05). Taijiquan has a significant effect on improving students' body shape, cardiopulmonary function, flexibility, balance, and mood.

Retinal Implantation of Electronic Vision Prostheses to Treat Retinitis Pigmentosa: A Systematic Review

Purpose

Retinitis pigmentosa (RP) is a hereditary disease causing photoreceptor degeneration and permanent vision loss. Retinal implantation of a stimulating electrode array is a new treatment for RP, but quantification of its efficacy is the subject of ongoing work. This review evaluates vision-related outcomes resulting from retinal implantation in participants with RP.

Methods

We searched MEDLINE and Embase for journal articles published since January 1, 2015. We selected articles describing studies of implanted participants that reported the postimplantation measurement of vision. We extracted study information including design, participants’ residual vision, comparators, and assessed outcomes. To assess the risk of bias, we used signaling questions and a target trial.

Results

Our search returned 425 abstracts. We reviewed the full text of 34 articles. We judged all studies to be at high risk of bias owing to the study design or experimental conduct. Regarding design, studies lacked the measures that typical clinical trials take to protect against bias (e.g., control groups and masking). Regarding experimental conduct, outcome measures were rarely comparable before and after implantation, and psychophysical methods were prone to bias (subjective, not forced choice, methods). The most common comparison found was between postimplantation visual function with the device powered off versus on. This comparison is at high risk of bias.

Conclusions

There is a need for high-quality evidence of efficacy of retinal implantation to treat RP.

Translational Relevance

For patients and clinicians to make informed choices about RP treatment, visual function restored by retinal implantation must be properly quantified and reported.
