Research on Application of Health Medical Information Science Data Sharing Standard System in Sports Rehabilitation

The development of medical information technology has rapidly promoted the development of medical information technology towards intelligence. Health medical data provides basic data resource protection for intelligent medical services and smart medical services. This article abstracts the typical models of domestic and international health medical information management services, and provides theoretical basis and practical reference for the building of an evaluation index system for health management service capabilities. An system for health management service capabilities under a data sharing standard system was constructed, and the status and linkage of health management services were investigated and comprehensively evaluated to provide an index system and empirical data for evaluating hospital health management service capabilities. Finally, analyze the advantages and disadvantages of health management services under the medical consortium framework, propose countermeasures to improve the health management service system, provide decision-making references for units to improve their health management service capabilities, optimize health management service models, and formulate health management services for relevant government departments Provisional policies to promote the implementation of health management.

Encapsulation of rat cardiomyoblasts with alginate-gelatin microspheres preserves stemness feature in vitro

INTRODUCTION

The emergence of numerous tissue engineering and regenerative medicine techniques cell encapsulation paves a way to heal and restore the function of various injured tissues mainly cardiovascular system. Here, we aimed to investigate the role of alginate-gelatin encapsulation on the dynamic of rat cardiomyoblasts in vitro.

MATERIALS AND METHODS

Rat cardiomyoblasts cell line H9C2 were enclosed by using alginate-gelatin microspheres and incubated for 7 days. MTT method was used to examine cell viability. The level of genes associated with cardiomyoblasts maturation MYL7, NPPA, NKX2-5, and GATA4 real-time PCR. ELISA was used to measure the protein levels of Bcl-2 and Bax factor post-encapsulation. The level of SOD, GPx, and TAC was detected by biochemical analyses. Western blotting was performed to measure the content of AMP-activated protein kinase.

RESULTS

We found that encapsulation was able to increase the viability of rat cardiomyocytes after 7 days. The decreased level of Bcl-2 (p < 0.001) coincided with non-significant differences in the level of Bax (p > 0.05). The transcription level of all genes MYL7, NPPA, NKX2-5, and GATA4 were found to down-regulate compared to the control non-treated cells (p < 0.05). No significant differences were found regarding the level of SOD, GPx, and TAC compared to the control (p>0.05). According to western blotting, revealed a reduced level of AMPK following 7-day incubation of rat cardiomyoblasts (p < 0.05).

CONCLUSION

Data confirmed that the encapsulation of rat cardiomyoblasts with alginate-gelatin microspheres maintained the cells multipotentiality.
