中文摘要：

目的：比较肺阴虚证肺功能分级和症状积分分级的结果，发现肺阴虚证肺功能分级法的可行性。方法：首先对病人进行中医证候学调查，然后对于属于肺阴虚证的，行肺功能检查分级。再对每一级行症状积分分级，比较两种方法的结果。结果：肺功能分级后，轻度肺阴虚证47例，中度肺阴虚证45例，重度肺阴虚证24例。在对肺功能分级的每度肺阴虚证行症状积分分级后，轻度中有轻度43例，中度4例，重度0例；中度中有轻度2例，中度42例，重度1例；重度中有轻度0例，中度2例，重度22例。两种方法结果比较无明显差异（P〉0．05）。结论：肺的一切生理功能均以肺主呼吸功能为基础。按：轻度FEV。占预计值百分比〉／50％，中度30％≤FEV1占预计值百分比〈50％，重度FEV1占预计值百分比〈30％的肺功能分级标准对肺阴虚证分级是可行的。

英文摘要：

Objective：Comparison resulsts between pulmonary function and symptom scores graduated method of Fei-Yin deficiency Syndrome,to develop that graduated method of pulmonary function is feasible. Methods ： Firstly investigate syndrome of TCM, then perform the test of pulmonary function to the patients of Fei- Yin deficiency Syndrome, and practice symptom scores graduation on every grade of graduated method of pulmonary function, at the end, comparison resulsts between pulmonary function and, symptom scores graduated method. Results：In the results of graduated method of pulmonary function, there are 47 cases in light-grade,45 cases in midrange,24 cases in weight-grade. And in the results of symptom scores graduation to every grade of pulmonary function graduated method,there are 43 cases of light-grade,4 cases of midrange ,0 cases of weight-grade in light-grade; there are 42 cases midrange,2 cases of light-grade, 1 cases of weight-grade in midrange;there are 22 cases of weight-grade,2 cases of midrange,0 cases of light-grade in weight-grade. Thereis nosignificant difference between pulmonary function and symptom scores graduated method （ P 〉 0. 05 ）. Conclusion ： All the physiological function of the pulmonary are based on mastering Qi and respiratory function, so graduated method of pulmonary function is feasible. The standard of pulmonary function graduation of Fei- Yin deficiency Syndrome：light-grade FEV1 percentage of the predicted value ≥50, midrange 30% ≤FEV1 percentage of the predicted value 〈 50%, weight-grade FEVl percentage of the predicted value 〈 30%.
