摘　　要：Background It is well recognized that meteorological factors have important influences on the onset and development of many kinds of diseases. The present study was undertaken to investigate the effects of the meteorological elements on admission rates of cerebral infarction patients with hypertensive nephropathy at Changchun city, Jilin Province, northeast China. Methods A total of 763 medical records of inpatients from nine hospitals at Changchun city, during a period from April 6 to April 17 in 2010, were reviewed. These patients were admitted to hospitals due to the occurrence of cerebral infarction. The hypertensive nephropathy was evidenced with certain diagnosis of essential hypertension and hypertension-related kidney injuries. The cerebral infarction was diagnosed according to the World Health Organization （Stroke） standard. All the meteorological data were from practical monitoring records in Jilin Province Meteorological Observatory. The relationships between the epidemiological prevalence of cerebral infarction and meteorological variables were analyzed using the time series models of statistics. Results Compared with admission rates before the violent change in meteorological status （April 6 to April 17, 2010）, the number of admission patients suffering from cerebral infarction remarkably peaked on April 12. Such an increase was highly correlated with heavy precipitation, elevation of daily average relative humidity, and reduction of average daily air temperature. With the betterment of the meteorological conditions on April 17, the admission rates of cerebral infarction patients dropped to the same level as the dates before snowing （April 6 to April 11）. Conclusions The meteorological changes are highly associated with the occurrence of cerebral infarction in patients with hypertensive renal injury in northeast China. This study also suggested that an intensive medical interference for those patients with hypertension-induced organ injuries is very necessary in preventing the occurrence Background It is well recognized that meteorological factors have important influences on the onset and development of many kinds of diseases.
