On the Frequently-used Prepositions in the Titles of Medical Articles Related to Acupuncture and Moxibustion

As the frequently-used words, prepositions show certain characteristics in English of medical science and some regularities in the construction of the sentences. However, it is so small that people might confuse and misuse their semantic items. In this paper, prepositions were extracted from English titles of 4 volumes in each key journal related to acupuncture and moxibustion. And, the usages of prepositions were counted, with the result of 1538 prepositions. The first five from the highest frequency to the lowest are “of”, “in”, “on”, “with”, and “for”. Then, an analysis and summary was made in terms of their semantic items, and a discussion was conducted from the view of the combination of their usages with the features of acupuncture and moxibustion. At last, a conclusion was made about the connection between the language of English and the discipline of acupuncture and moxibustion.
