对32例慢性支气管炎并活动性肺结核与40例慢性支气管炎急性发作病例进行比较。认为在两病鉴别论断上有价值的临床表现为：咯血、胸痛、刺激性咳嗽、喘息首次出现或经治不愈、盗汗，肺结核既往史，胸水、肺不张及胸片上结核活动灶。同时发现慢性支气管炎并活动性肺结核最多见误诊为慢性支气管炎急性发作（26／32），其次为肺报（6／32）。 32 cases of chronic bronchitis and active tuberculosis and 40 cases of acute exacerbation of chronic bronchitis were compared. It is considered that the valuable clinical manifestations in the identification of two diseases are: hemoptysis, chest pain, irritating cough, wheezing first time or unhealed, night sweats, past history of tuberculosis, pleural effusion, atelectasis and chest X-ray activity. Also found that chronic bronchitis and active tuberculosis are the most common misdiagnosed as acute exacerbation of chronic bronchitis (26/32), followed by pulmonary (6/32).
