摘要: 目的探讨纤支镜肺泡灌洗液中结核分枝杆菌DNA在肺结核诊断中的价值。方法对187例初治肺结核患者及41例肺炎患者分别应用荧光定量聚合酶链反应(FQ-PCR)技术检测结核分枝杆菌DNA、肺泡灌洗液结核菌培养、纤维支气管镜刷片抗酸染色。结果肺结核患者肺泡灌洗液结核分枝杆菌DNA阳性率为:78.6%、肺泡灌洗液结核菌培养阳性率为28.8%、刷片抗酸染色阳性率为21.9%。肺炎患者肺泡灌洗液结核分枝杆菌DNA、肺泡灌洗液结核菌培养、刷片抗酸染色均阴性。结论荧光定量聚合酶链反应检测肺泡灌洗液结核分枝杆菌DNA,特异性高,用于肺结核诊断可提高肺结核诊断的敏感性和准确性,明显优于纤维支气管镜刷片抗酸染色,亦较肺泡灌洗液结核菌培养诊断灵敏、快速,可作为肺结核诊断较可靠指标。

Abstract: Objective To study the value of detecting M.tuberculosis DNA in bronchoalveolar lavage fluid(BALF) by fluorescent quantitative polymerase chain reaction(FQ-PCR) in diagnosing pulmonary tuberculosis.Methods The BALF from the 187 patients with pulmonary tuberculosis treated first and 41 patients with pneumonia were detected the M.tuberculosis DNA(TB-DNA) by FQ-PCR,and performed mycobacterial culture.The bronchoscopic brushing smears were detected by acid-fast staining.Results The positive rates of detecting B...
