广东省老年尘肺1036例X线分析

Radiographic analysis of 1036 cases suffering form geriatric pneumociniosis in Guangdong

本文对广东１０３６例（矽肺４５０例、煤工尘肺５８６例）男性老年尘肺Ｘ线胸片进行了分析。结果：老年矽肺Ｘ线表现上类圆形小阴影“ｑ”发生率７２４５％，不同时期“ｑ”影发生率与对照组无差异（Ｐ＞００５）。老年煤工尘肺（ＣＷＰ）Ｘ线形态以不规则形小阴影“ｓ”（３２０８％）、“ｔ”（３２０８％）为主。不同时期“ｓ”影发生率高于对照组（Ｐ＜００１），而“ｔ”影发生率低于对照组（Ｐ＜００１或Ｐ＜００５）。老年尘肺组各晋期年限均比对照组要长，其中死亡病例晋期年限较对照组有显著性差异（Ｐ＜００１）。作者认为，广东省老年矽肺Ｘ线形态以“ｑ”影为主，老年ＣＷＰ以“ｓ”“ｔ”影为主。有“ｓ”“ｔ”影的尘肺患者较有“ｑ”影者预后较好。晋期年限较长者提示较长寿。

Radiographic 1036 cases (silicosis 450 cases and CWP 586 cases)manifestation of male geriatric pneumoconiosis(GP group) in Guangdong had been analysed Results were as follows:the prevalence of small round opacities “q” in radiographic manifestation of geriatric silicosis (GS) was 72 45 per cent The prevalence of “q” between different period of GS and control group( P >0 05) showed no statistical significance The radiographic manifestation of geriatric CWP was dominated as small irregular opacities “s” (32 08 per cent)and “t”(32 08 per cent) The prevalence of “s” in geriatric CWP was singnificantly higher than that of control group in the different period ( P <0 01) The prevalence of 't' in geriatric CWP was significantly lower than that of control group in different period( P <0 05 or P <0 01) The average duration from stage 0 to I,stage I to Ⅱ and stage Ⅱ to Ⅲ in GP group were longer than that of control group,whereas the significant difference was only shown between dead cases and control( P <0 01 Conclusions:the radiographic shape of GS was dominant in small round opacities “q” whereas that of geriatric CWP was small irregular opacities “s” and “t” in Guangdong The prognosis of “s” and “t” seemed to be better than that of “q” in the pneumoconiosis Longevity will be predicted by the longer duration of progression stage of pneumoconiosis in GP
