The keyword of "" ranked first in research frontiers and appeared earlier, and the keyword of "microbiota" began to appear in the past 3 to 5 years. The annual number of publications would continue to grow. Besides the traditional related researches, future research hotspots will focus on microbiota and its mechanism of action.
