摘　　要：目的研究钼矿矽肺患者肺功能损伤情况,分析胸片表现与肺功能参数的关系。方法65例钼矿矽肺患者和30例健康成人,均进行肺通气功能检查及拍摄胸部正位片。比较不同胸片表现患者其肺功能参数的情况。结果⑴随着尘肺期别的增高,各肺功能参数值呈下降趋势,与对照组比较,一期、二期、三期尘肺患者各项肺功能参数均有明显差异,尤其是FEV1.0,75,50和25;各期患者比较,上述四项参数亦有明显差异(P<0.05)。⑵随着矽肺损害累及肺区数的增加,各项肺功能参数也有轻微下降,当出现尘肺大阴影时,下降更明显,特别是FEV1.0,75,50和2(5P<0.05),但在累及4、5、6肺区之间比较无明显差异。⑶小阴影形态及密集度的不同与肺功能参数变化关系不大。结论矽肺患者肺通气功能主要与矽肺期别及大阴影的形成和程度相关。Objective To study the affected degree of pulmonary function of silicosis sufferers in molybdenum mine and its relationship with the characteristics of chest X-ray film. Methods The pulmonary, function and chest radiography of sixty-five silicosis cases in molybdenum mine and thirty healthy cases were carried out and the pulmonary function parameters in different chest X-ray manifestation were analyzed. Results （1）With the grading of silicosis category, each pulmonary function parameter decreased gradually. Compared with control group, silicosis cases in radiographic category I, 11 ,m had significant decrement of all parameters, especially FEVL0,^·V75,^·V50 and ^·V25（P 〈 0.05）. There were also statistical difference of these four parameters among silicosis cases in category Ⅰ, Ⅱ and Ⅲ. （2） The parameters level of silicosis cases were slightly decrement following the increment of silieotic lesion regions. If progressive massive fibrosis was noted, the parameter FEVL0,^·V75,^·V50 and ^·V25 significantly decreased（P 〈 0.05）, if the region 4,5 and 6 was affected, no difference was found. （3） No relation was found between the change of pulmonary function parameters and form or density of small opacities of silicosis. Conclusion The pulmonary ventilation function is mainly in relation to silicosis category or the formation and the degree of massive fibrosis.
