纤维支气管镜诊治支气管异物24例临床分析

Diagnosis and treatment of bronchus foreign body by fiberbronchoscope:an analysis of 24 cases

摘要: 目的：探讨纤维支气管镜(纤支镜)在支气管异物诊断及治疗中的作用。方法：对24例经纤支镜确诊和治疗的支气管异物患者的临床资料进行回顾性分析。结果：主要临床表现为咳嗽、咳黄痰、发热、咯血、喘息，体格检查有呼吸音减低、吸气相干啰音及湿啰音；院外误诊为肺癌4例，肺炎4例，肺结核2例，支气管哮喘1例，结核性胸膜炎1例；右侧异物17例，左侧7例；动物性异物14例，植物性异物6例；均经纤支镜取出。结论：支气管异物临床上容易误诊，纤支镜在支气管异物的诊断和治疗中具有重要的意义。

Abstract: Objective:To investigate the expression of let-7b in breast cancer. Methods:Using tissue microarray platform and applying in situ molecular hybridization technique for detecting the expression of let-7b in 80 cases of human breast cancer,22 cases of benign breast disease. Results:The positive rates of let-7b was 35.0% in the breast cancer,it was lower than 59.1% in the benign breast disease(P0.05). Conclusions:Down-regulation of let-7b expression might play a role in the pathogenesis and progression of breast cancer.
