本文报告对80例非吸烟健康人及50例吸烟健康人进行了MTT、MTT_(P(3))、MTT_(P(6))、TT_(P7)、TT_(P8)及TT_(P9)的测定,统计学分析表明,上述各指标与年龄呈中度直线负相关关系(P<0.01～0.001),而与性别无显著相关(P>0.05)。按照男、女及两性对上述各指标、FEV_1/FVC、MMEF、(?)_(50)/H及(?)_(25)/H各指标分别计算出与年龄相关的直线回归方程式、相关系数及SEE、依据方程式预计值±1.645倍SEE作为正常值上限或下限,对50例吸烟健康人进行异常率检验,结果表明:TT_(P7)、TT_(P8)、MTT_(P(3))及MTT_(P(6))、MMEF及(?)_(25)/H的异常率较高,其中新提出的TT_(P7)、TT_(P8)及MTT_(P(3))更为敏感,测量计算更简便。
This article reports the MTT, MTT_ (P (3)), MTT_ (P (6)), TT_ (P_7), TT_ (P_8) and TT_ (P_9) of 80 healthy non-smokers and 50 healthy smokers Measurement and statistical analysis showed that there was a moderate linear negative correlation between the above indexes and age (P <0.01 ~ 0.001), but no significant correlation with gender (P> 0.05). According to the above indexes, FEV_1 / FVC, MMEF, (?) _ (50) / H and (?) _ (25) / H, the age-related linear regression equations were respectively calculated according to the male, Coefficients and SEE were used to test the abnormality rate of 50 smoking healthy people according to the expected value ± 1.645 SEE of the equation as the upper limit or the lower limit of normal. The results showed that TT_ (P7), TT_ (P_8), MTT_ (P_ (3) And MTT_ (P (6)), the abnormal rates of MMEF and (?) _ (25) / H were higher, and the newly proposed TT_ (P7), TT_ (P8) and MTT_ (P (3) , Measurement and calculation easier.
