Objective　To explore the high-sensitive solar terms and dominant meteorological factors in the onset of cerebral infarction,and to analyze the influence of daily temperature range and 24-hour temperature change on hospital admissions for cerebral infarction.Methods　Patients with cerebral infarction who were hospitalized in the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and the Second Hospital of Tianjin Medical University from January 2019 to December 2020 were retrospectively collected.The patients were grouped according to the twenty-four solar terms to explore the high-sensitive solar terms for the admission of cerebral infarction.A generalized linear Poisson regression model was established to explore the relationship between temperature changes and cerebral infarction admissions.Results　This study finally included 17 518 patients with cerebral infarction.There were statistically significant differences in the daily temperature range among different solar terms (P<0.001).The larger stages of the daily temperature range were from “Awakening of Insects” to “Grain in Ear”,and from “Autumn Equinox” to “Beginning of Winter”.The high-sensitive solar term of cerebral infarction admission was“Cold Dew”,which was located in the period of large daily temperature range.Daily temperature range was associated with cerebral infarction admission after multivariate adjustment (RR=1.01,95%CI 1.00~1.02,P=0.017),and had a hysteresis effect.With the increase of daily temperature range,the risk of cerebral infarction admissions increased,especially in males.Conclusion　“Cold Dew” is the high-sensitive solar term for cerebral infarction admission,and daily temperature range may be the dominant meteorological factor.The admission of cerebral infarction is related to the daily temperature range.
