Preliminary Analysis Of Association Of Yunqi Theory And Meteorological And Epidemic Disease

As a basic theory of traditional Chinese medicine, the theory of Yunqi played an important part in traditional Chinese medicine. However, many researches on the theory are not reasonable because the ancients described the theory in a speculative and philosophical manner and the dynamicity of the theory was often being ingnored. For further study of Yunqi theory, this article tries to do some preliminary analysis of association of Yunqi theory and meteorological and epidemic disease with the following three aspects:(1)As the ancients summarized the Yunqi theory during their struggle with disease and nature, this article will try to study the Yunqi theory from the perspective of Meteorology. Specifically, we introduced the effective temperature, one of the meteorological index, which can reflect the true feeling of the human body from the external environment to show the reasonableness of the theory and demonstrate that Yunqi theory is more suitable for the Central Plains.(2)Canon of Internal Medicine said,"Time is constant but Qi is not", which suggests that the actual use of Yunqi theory should be in according with the variability of external environment. Based on this, this article took influenza A(H1N1), Foot and Mouth diseaseand H7N9influenza as examples, used the meteorological and epidemic data along with the Yunqi theory to discuss the variation trend of endemic situation. The results indicate that Yunqi theory canexplain the changes of epidemic disease, and we can grasp the inherent laws of Yunqi theory through its dynamic changes and use its objective and rational kernel for help. In practical application, meteorological data can be used to analyze the dynamic changes of Yunqi:firstusing the theory of "pestilence every3years"to analyze whether "gang rou shi shou(刚柔失守)”had appeared, then choosing corresponding meteorological factors toobserve the changes of the Sixqi(六气)at the beginning of each Sixqi period, and then analyzing the practical changes of Keqi(客气).(3)Since the generation of smog was closely related to the change of the weather, Yunqi theory can be used to analysis the smog as it contains the explaination of climate change. This article analyzes the smog in the history of Beijing according to the number of the appearance of smog. The result suggests that smog has obvious interannual variation. Smog appeared more often from1980to the beginning of the20th century than the recent10years. From the aspect of Yunqi theory, smog usually appears when Zhuqi(主气) is taiyanghanshui(太阳�'水)or yangmingzaojin(阳明燥金)or jueyinfengmu厥阴风木)And when Keqi客气)becomes jueyinfengmu(厥阴风木)or taiyinshitu太阴湿土),the smog also shows up.Yunqi theory plays an important role in the prediction of epidemic disease, so it is necessary to strengthen the research of the theory. Based on comprehensive analysis of Yunqi theory, meteorological data and epidemic disease data, we find that Yunqi theory has its rationality and we also provide a reference for the application of the theory. Through the analysis of the smog in the history of Beijing, we also expand the research range of Yunqi theory.
