摘要
本文对156例COPD患者的CV/VC(%)与FMF作了相关性分析,求出了相关系数(r=0.6812,P<0.001)和直线回归方程式。两者呈中度负相关,说明CV/VC(%)随着FMF曲降低而增高。用此方程式计算的CV/VC(%)与实测的CV/VC(%)呈高度正相关(r=0.8935,P<0.001)。对另一组175例COPD患者的FEV_1%、FMF及推算和实测CV/VC(%)的异常率也进行了分析。结果表明FMF异常率均高于CV/VC(%)的计算值和实测值。在FEV_1%≥80%的患者中,FMF的敏感性也高于FEV_1%。作者认为FMF可作为COPD筛选和早期诊断可靠、敏感的一项指标。
The cv/vc% and FMF of 156 cases with COPD were analysed. The equation of linear regression was formed and showed negative correlation (r=-0.6812, P<0.001). Using above-mention equation, cv/vc % was deduced. The deduced cv/vc% and measured cv/vc% showed better positive correlation(r=0.8935, P<0.001). The abnormalities of FEV_1%, FMF, deduced cv/vc% and measured cv/vc% in another group (175 cases)were analysed. The results showed that the percentage of FMF abnormality was higher than deduced cv/vc% and measured cv/vc%. In the group of FEV_1%≥80%, the sensitively of FMF was higher than FEV_1%. The authers concluded that FMF is a sensitive and reliable index for selecting and early diagnosing COPD patients.
