为了解壳变钙化在煤工尘肺中的发生率和反映尘肺早期病损的价值,首先在钙化发生率较高的中条山有色金属矿山矽肺患者中进行了全面调查,然后在大同、阳泉和太原西山等三个地区的国家统配煤矿和地方煤矿进行了全矿煤工尘肺系统胸片的回顾调查,核实I期尘肺、肺门环钙和壳变钙化确诊时间及其相互关系,查清它们的发生率和早期诊断价值,证实壳变钙化是煤工尘肺的早期病损和早期诊断指标之一。病灶钙化是病理改变的晚期表现,而肺脏淋巴系统尘肺病灶钙化却主要显现在确诊尘肺之前。尘肺前期,病理上能看到肺门淋巴结肿大和淋巴结中矽结节形成,X线有时可显示肺门淋巴结蛋壳样钙化和肺野内壳变钙化影像,均为粉尘首先侵犯肺脏淋巴系统的结果。煤工尘肺和矽肺一样,胸片上可显示三种特异性钙化表现,即肺门淋巴结环形钙化(annular calcification)又称蛋壳样钙化(egg-shell calcification,简称肺门环钙),壳变钙化(shell-changing calcification)和矽结节钙化(silicatic no-dulare calcification)。六十年代以来,国内外学者就重视了肺门环钙,ILO和我国的尘肺X线诊断标准都将其作为尘肺征象的记号(symbols)之一(即es)。七十年代初期,国内学者连续报道了es在尘肺早期诊断中的价值。根据我们的观察(1984),粉尘作业工人肺野内壳变钙化较肺门环钙出现早而发生率高。为了检验壳变钙化和肺门环钙在煤工尘肺中的发生和早期诊断价值,我们在不同矿区进行了调查。 In order to understand the incidence of shell variable calcification in coal workers’ pneumoconiosis and reflect the value of early lesions of pneumoconiosis, a comprehensive investigation was first carried out in patients with silicosis of Zhongtiaoshan non-ferrous metal mine with a high incidence of calcification. Then, Taiyuan Xishan and other three regions of the national coal mines and coal mines carried out coal miners pneumoconiosis chest X-ray review of the investigation to verify I pneumoconiosis, hilar calcium and shell variable calcification of the time and their correlation to find out their The incidence and early diagnosis of CSC confirmed that shell calcification is one of the early lesions and early diagnosis of coal workers’ pneumoconiosis. Lesions of calcification is a late manifestation of pathological changes, and lung lymphatic system, pneumoconiosis lesions mainly appear in the diagnosis of pneumoconiosis before. Pneumoconiosis, the pathological can see the hilar lymph nodes and lymph nodes in the formation of silicon nodules, X-ray can sometimes show hilar lymph node eggshell calcification and lung field within the shell calcification images, are the first violation of the results of lung lymphatic system . Coal workers pneumoconiosis and silicosis, chest X-ray can show three specific calcifications, hilar lymph node ring calcification (annular calcification), also known as egg-shell calcification (egg hilar calcium), shell calcification shell-changing calcification and silicatic no-dulare calcification. Since the 1960s, domestic and foreign scholars have attached importance to the hilar calcium, ILO and pneumoconiosis diagnostic criteria in our country as one of the symbols of pneumoconiosis (ie, es). In the early seventies, domestic scholars reported the value of es in the early diagnosis of pneumoconiosis. According to our observations (1984), the incidence of shell calcification in the lung field of dust-exposed workers was higher than that of the hilar ring calcium. In order to examine the occurrence of shell calcification and hilar calcium in coal worker’s pneumoconiosis, we conducted a survey in different mining areas.
