PurposeHealthcare employs informatics to offer its services through information technology where the social network can aid virtual medical learning. Since the usage of the internet and other electronic tools for medical services delivery is at the initial stage, it is essential to examine the factors that condition patients and medical elements in a virtual environment can develop relationship models on the health services. So, the authors have systematically reviewed virtual medical learning and offered some suggestions for the upcoming works. The authors have also discovered gaps in the state-of-the-art papers and provided solutions for them.Design/methodology/approachNumerous novel advancements have changed the old exercise of therapeutic and analytic learning. Virtual spaces have quickly turned into a section of the learning technology vision. Given the importance of its achievements and endless low-cost expansion of the educational system, virtual education has been considered as one of the issues raised by the information communities. Medicine and health are some of the most important fields in virtual technologies. Hence, in this paper, we have used a systematic literature review to deeply examine virtual medical learning. After establishing exclusion and inclusion criteria, an independent systematic search in Google Scholar, ACM, Scopus, Eric, Science Direct, Springer link, Emerald, Global ProQuest and IEEE for relevant studies have been performed, and 21 papers have been analyzed. Detailed data have been mined out of the papers.FindingsThe authors have found that virtual medical learning improves and expands the knowledge core and meaningfully affects the exercise. Virtual learning (VL) has been used in many therapeutic zones, like therapeutic learning, surgery, diagnosing, combining and regularizing processes. It has presented a fundamental access point and a referral mechanism for all of a course's component communities. It can also simplify communicative education, allowing learners to get abilities before applying them in a real-world situation. Also, the communicative characteristics of different VL programs can somehow be like direct teaching.Research limitations/implicationsSome excellent work may be removed owing to applying the filters to select the primary papers. Surveying all the documents on the topic of virtual medical learning is impossible, too. Nevertheless, the authors have tried to present a perfect survey of virtual medical learning. The results will be helpful for scholars to propose better virtual medical learning techniques.Practical implicationsE-learning has become an indispensable additional learning tool in medical education. The introduction of new learning technologies, the exponential growth of Internet usage and the advent of the World Wide Web can change the face of higher education. The results will be helpful for scholars for the upcoming works. The application of a literature review of partial least squares theory was useful for offering comprehensive literary coverage and completing the knowledge development analysis. The authors have backed scholars and experts for better understanding the development of virtual medical learning systems via presenting comparative data and scrutinizing the present advances.Originality/valueThe paper enhances intellectual knowledge by improving the conception of virtual medical learning. It informs the development, use of virtual medical learning and the upcoming works. The lack of comprehensive papers in this field has increased the importance of this paper. The present paper can handle the pace of publications.

Nanotechnology and Nanomaterials has been applied in sports widely. Such as human movement science, sports halls, facility, equipment etc. The contribution of nanotechnology and nanomaterials for physical culture and sports is significant. However, nanotechnology and nanomaterials maybe cause some potential adverse effects on body and environment. The special biological effect and the safety should not be neglected. Human beings should increase the basic research and epidemiological investigations about environment-health-safety of nanomaterials, to provide accurate exposure levels and the guiding principles of nanoparticles risk, to provide the necessary theoretical basis for establishing the standard of nanomaterials production and work place environment. With the attention of the whole world, the safety problems for nanotechnology and nanomaterials will be solved finally. We can get the most benefit from nanotechnology and nanomaterials, but the least safety trouble.

Objective  The purpose was to further improve the understanding of exercise to improve dyslipidemia and to formulate exercise prescription more scientifically. It provides a reference for the further study of exercise mimics in the treatment of dyslipidemia and helps to reduce the high incidence of dyslipidemia. Methods Methods of documentation and comparative analysis are applied.  Results It was found that the effects of exercise on dyslipidemia were beneficial or had no obvious effect on some indexes so far, and had no adverse effect. The biological mechanism of exercise regulating dyslipidemia and the effects of different exercise forms (acute exercise, long-term exercise training, different intensity exercise) on improving dyslipidemia were summarized. It is pointed out that exercise plays an important role in regulating the enzymes and proteins associated with dyslipidemia.  Research from several aspects :exercise to block cholesterol biosynthesis, exercise inhibits cholesterol absorption, exercise affects cholesterol conversion, exercise promotes cholesterol conversion to bile acid, and exercise promotes cholesterol metabolism, exercise regulating triglycerides, etc. Conclusions The regulation of dyslipidemia is a complex process, involving multiple pathways, multiple gene regulation, and different hypolipidemic pathways.A large number of experimental studies have demonstrated the effect of exercise on the improvement of dyslipidemia, but there are few studies on the biological mechanism of exercise, which need to be further studied.In addition, when chemically synthesized anti-hyperlipidemia drugs have many safety problems, we should increase the in-depth study of sports drugs, especially some natural products, that can simulate exercise effectiveness. In order to better control the high incidence of dyslipidemia, it is necessary to improve the development of exercise mimic drugs in improving dyslipidemia.
