61例传染性非典型肺炎患者舌象与气候因素相关性的研究

Study on Correlation between Climate and Tongue Sygns of 61 Patients with SARS

目的探讨2003年1～4月61例传染性非典型肺炎患者舌象与气候变化的相关性,为本病的防治提供线索。方法按照临床流行病学研究方法,前瞻性阶段调查2003年1～4月61例传染性非典型肺炎患者(病例组)的舌象并与普通肺炎发热患者151例(对照组)比较;同时调查该时段广州地区气候的变化。结果广州地区属于湿热气候,2003年1～4月气温、湿度均比历年偏高;病例组的湿热舌象较对照组更明显,同时病例组舌象还表现出明显的气虚倾向。结论传染性非典型肺炎的发病可能与当地气候异常、患者发病前存在正气不足等有关,其舌象反映了传染性非典型肺炎火热的病机,并提示湿邪与传染性非典型肺炎有密切关系。

To study the correlation between climate and Tongue Signs of 61 patients with SARS,so that some clues may be obtained for the disease's therapy and prevention.Methods:Cliniacal epidemical methods were adpoted.Forward- looking investigations were applied on 61 patients with SARS from January to April of the year 2003 refered as the case group.Their Tongue Signs were compared with those of 151 patients that suffered a fever caused by pnemonia refered as the comparision group.Climate of Guangzhou(广 州 ) in that period was also studied.Results:Guangzhou 's climate has wet and hot quality.Temperature and wet degree in this region from January to April of the year 2003 are both higher and wetter than those of previous years.Wet and Hot Tongue Signs were more evident in the case group than in the comparision group in which a more significant trend of Deficiency of Qi existed indicated by patients' Tongue Signs.Conclusion:Outbreak of SARS may be correlated with abnormal climate of local region and Deficiency of Vital Qi of uncaught patients. Hot mechanism of SARS were implied by the patients' Tongue Signs which also suggests a close bond between Damp Pathogen and SARS.
