119例肺结核患者痰涂阳与胸部X线表现的对比研究

目的 探讨肺结核患者痰涂阳与胸部X线表现之间的关联性，为有关科室及时采取措施防治结核病提供参考。方法 对119例肺结核患者痰涂阳与胸部X线表现进行回顾性分析，按痰涂阳1+～2+和3+～4+将其分为痰涂阳程度低和程度高的两组作对比研究，对结果采用SPSS 13.0统计软件进行处理；采用χ²检验及多因素非条件logistic回归分析进行统计学处理，以P<0.05为有统计学意义。结果 肺结核患者是否具有传染性（即痰涂阳）与肺结核病灶分布部位（涂阳1+～2+组与3+～4+组在左右肺病灶分布分别为90个和88个，经比较：χ²=0.208，P=0.649）、范围（本组涂阳1+～2+组其病灶范围为2.37个肺野/例：180个/76例；3+～4+组为2.33个肺野/例：100个/43例，χ²=0.006，P=0.936）、空洞大小(χ²=3.300，P=0.069,OR=2.028, 95% CI：1.012～4.350)、有无引流支气管（χ²=0.092，P=0.761，OR=0.889,95% CI：0.418～1.894）的差异无统计学意义；与其分型（本组Ⅲ型110例，占92.4%）、分期（本组进展期79例，占66.4%；好转期33例，占27.7%；稳定期7例，占5.9%）、X线表现中空洞分布范围（χ²=13.553，P=0.000, OR=2.283，95% CI：1.471～3.543）、数目（χ²=15.427，P=0.000, OR=2.474，95% CI：1.574～3.887）、洞壁情况（χ²=11.166，P=0.001, OR=2.691，95% CI：1.506～4.808）等差异有统计学意义。结论 肺结核患者痰涂阳及菌量与胸部X线表现之间有明显的关联性。

A comparative study of the correlation between sputum smears positive and the chest X-ray features of 119 comes with pulmonary tubercolosis

Objective To explore the correlation between sputum smear-positive and chest X-ray features of patients with pulmonary tuberculosis(PTB) in order to provide the reference for management of PTB. Methods Chest X-ray features of 119 cases of smear-positive pulmonary tuberculosis who were divided into two groups according to sputum-smear 1+ to 2+ or 3+ to 4+ were reviewed and analyzed by Chi square and multivariate non-conditional logistic regression analysis with P<0.05 being considered statistically significa...
