Because of swainonine-producing endophytic fungal, Oxytropis glacialis is one of the main poisonous weeds in the alpine grassland and desert grassland of the Qinghai-Tibet Plateau (QTP). It has a severe impact on grassland degradation on the QTP. In this manuscript, the Internally Transcribed Spacer (ITS) region of fungal communities in the soil of the O. glacialis root system was sequenced by high-throughput sequencing and analyzed by bioinformatics methods. The physical and chemical properties of the soil samples were analyzed in combination with the fungal diversity and its relationship with the soil physical and chemical factors. The results showed that the soil fungal community in the O. glacialis root system are rich in diversity in different ecological environments and are most affected by the soil pH value and organic matter. The swainonine-producing fungal Embellisia oxytropis was first detected in the soil of the O. glacialis root system. This finding provides data to support the next step in demonstrating the horizontal spread of swainone-producing fungal from O. glacialis to soil. In addition, a stable network of core flora has a facilitating effect on the formation of O. glacialis as a dominant species in alpine ecosystems.

Objective: Analyze the research hotspots and frontiers of shared outpatient service, and provide a reference for researchers in this field to carry out follow-up research. Methods: Search the Web of Science core collection database until 2022 and visually analyze keywords in this field through CiteSpace5.8.R3 software. Results: A total of 261 literatures were included. The research focuses mainly on advanced care planning, diabetes care, and group prenatal care. The research trend tends to be telemedicine and nursing provided by specialized nurses. Conclusion: Scholars can learn from the research hotspots of foreign shared medical appointments, pay attention to the research trend, expand its application scope in combination with China's national conditions, and further promote the development of shared medical appointments in China.
