Objective:To study the agreement of Heavenly Stems 60 years with the changes of actual temperature of 60 years in Beijing with and method.Methods: To compare the temperature data of 60 years in Beijing using and methods.First,60 years are classified according to ten Heavenly Stems ,Five Movements and Too much and less models,and calculates the daily average temperature of three modes;Second,Qualitative comparison:the daily average temperature of the three modes higher than the average daily temperature of 60 years can be called heat,lower than that called cold;Third,Quantitative comparison:to have non-parametric tests or analysis of variance of the three modes of daily average temperature with the Mann-Whitney U method or SNK test for multiple comparison.Results:The Heavenly Stems 60 years and 60 years of actual temperature changes of the Beijing area are consistent in qualitatively study.They are not consistent in quantitative study.The temperature changes were not statistically significant(P0.05).Conclusion:the models of the climate changes calculated by Heavenly Stems is meaningful in qualitative study(cold and heat),but they have no statistical significance in quantitative study(temperature difference).
Objective: To research the correlation among incidence of coronary heart disease(CHD),six-qi and climate in Beijing area,discuss the influence of climate factors in the incidence of CHD.Methods: 1 901 cases in the cardiovascular department of Dongzhimen hospital from 1997 to 2007 were divided and calculated by six-qi theroy.Meteorological data was provided by observatory of Beijing.Temperature,vapor pressure,relative humidity,precipitation,wind speed,low cloud cover and comfort index were regarded as variables,and the cases of coronary heart disease as dependent variable.Single factor partial correlation analysis and multiple linear analysis was used to deal with datas.Results: The numbers of CHD patients in the first,fifth,sixth stages were more than in other stages.Totally,the incidence of CHD was negatively correlated with air temperature,relative humidity,vapor pressure and wind speed,and positively correlated with precipitation,low cloud amount and comfort index,in which relative humidity and wind speed was statistically significant(P0.05,P0.01).Conclusion: The incidence of CHD influenced mainly by wind speed and relative humidity showed certain regularity in six-qi stage,which is consistent with the etiology of six-qi in TCM theory.
Objective: To explore the correlation between the incidence of dysentery and climate changes(including the climates of corresponding years and the previous years) from the perspective of six climatic factors doctrine in traditional Chinese medicine(TCM) doctrine of five evolutive phases and six climatic factors.Methods: The cases of dysentery and meteorological data in Beijing from 1970 to 2003 were collected.All the data were categorized according to the six climatic factors stage and calculated by the correlation analysis method.The multiple stepwise regression was used to analyze the correlation between the meteorological factors and dysentery.A regression equation was created and tested.Results: The dysentery incidence was higher during summer and autumn.The incidence of dysentery was closely related with temperature,wind speed and relative humidity,of which wind speed was selected to the regression equation.The regression equation of dysentery and the corresponding years' meteorological factors was Y=-171226.89+86883.679 Xw.1(Xw.1 is the wind speed of 1st stage of climatic factors in the corresponding year).The regression equation of dysentery and the previous meteorological factors was Y=-291070.976+62177.339 Xw'.1+62776.246 Xw'.2(Xw'.1 is the wind speed of 1st stage of qi,and Xw'.2 is the wind speed of 2nd stage of climatic factors).Conclusion: Regression equation of the previous year was better than the current years' in predicting the prevalence of dysentery.It was feasible to predict the prevalence of dysentery by using the meteorological data in previous year.
Objective To study the correlation between the incidence of dysentery in Beijing area and meteorological factors three ago and in current year based on theory of pestilence occurring after three years.Methods The data of dysentery incidence in Beijing area from 1970 to 2004(35 years) and meteorological data at the same period were given correlation,regression and statistics analysis.The correlation between the incidence of dysentery and meteorological factors three ago and in current year was discussed.Results The incidence of dysentery was significantly related to temperature,wind speed and relative humidity three ago(P0.05).The wind speed of the second qi(from six qi in theory of five circuits and six qi) was chosen into stepwise regression equation,and regression equation was Y=-260768.31+113844.99X2(2).The incidence of dysentery was significantly related to temperature and wind speed in current year(P0.05).The wind speed of the first qi was chosen into stepwise regression equation,and regression equation was Y=-175 561.65+89 055.08X2(1).Conclusion The incidence of dysentery is correlated to climatic changes three ago,and theory of pestilence occurring after three years can used for forecasting the incidence of dysentery.
Objective:Based on the theory of 'transformation of plague in three years',to investigate the relationship between the incidence of dysentery and climate changes three years ago.Methods:By extraction of 35 years of dysentery high-risk years in Beijing from 1970 to 2004,and analysis its climate change characteristics three years ago,to evaluate 'the relationship of abnormal climate and dysentery disease' based on the theory of 'transformation of plague in three years'.Results:The high incidence of dysentery was related to the abnormal climate changes three years ago,especially in the Niangan years of wu,gui,xin.Conclusion:The incidence of dysentery was related to the climate changes three years ago,the theory of 'transformation of plague in three years' could predict the dysentery disease.
