北京地区脑梗死发病与干支运气及气象因子的关联性研究

目的  基于运气理论中对岁运、主气六气与疾病发病相关的认识，通过对脑梗死住院数据的分析，探讨其理论的科学性，并探索脑梗死发病与气象因素的相关性。方法  利用北京中医药大学东直门医院12年脑梗死住院数据，共3832例，计算不同运气时段脑梗死住院人数占同时段住院总人数的构成比，分析脑梗死住院人数构成比在不同运、气时段的差异；并将每年24节气住院数据与同节气及前一节气气象因子做相关性研究。结果  脑梗死的住院构成比，在不同天干岁运时段，以水运不及之辛年最高；在不同主气六气时段，以三之气最高。脑梗死发病与同节气的平均气温、平均水汽压和平均相对湿度呈正相关，同时前一节气的平均气温、平均水汽压、平均相对湿度和平均低云量亦与脑梗死发病有关。结论  脑梗死的发病在不同的天干岁运、主气六气时段中有一定差异性，脑梗死发病与气象因素相关。

Objective To discuss the scientificity of five circuits and six qi in circuit theory, and explore the correlation between cerebral infarction morbidity and meteorological factors based on the cognition of circuit theory to the relationship between circuit of year or six qi and disease morbidity and through analyzing the hospitalization data of patients with cerebral infarction (CI). Methods The hospitalized data of 3832 cases of CI for 12 y were collected from the Dongzhimen Hospital of Beijing University of Chinese Medicine for calculating the constituent ratio of hospitalized CI cases at different periods of circuit of year to total hospitalized CI cases at the same periods, and analyzing the difference in the constituent ratio of hospitalized CI cases at different periods of circuits or qi. The correlation was studied between hospitalized data at 24 Solar Terms every year and meteorological factors at the same Solar Term or meteorological factors at prior Solar Term. Results The constituent ratio of hospitalized CI cases was the highest at Xin year of waterless-circuit among different Heavenly Stems, and in the third qi among different Dominant qi. The morbidity of MI was positively correlated to average temperature, average vapor pressure and average relative humidity at the same Solar Term, and correlated to average temperature, average vapor pressure, average relative humidity and average low cloudiness at prior Solar Term. Conclusion The morbidity of MI has difference at different Heavenly Stems, circuits and six qi periods, and correlated to meteorological factors.
