目的提高对藏北那曲高原地区肺结核X线表现的认识。方法藏北那曲地区1996年7月至1999年9月间肺结核117例,初诊均拍摄胸部平片,并与沿海城市湛江同期、同年龄109例肺结核作对照,按1998年结核病新分类法分类,作者用双盲法分析两组的X线表现,用χ2检验作统计分析。结果(1)原发型肺结核比例高,占7.69%,其中成人比例高,占4.3%,对照组继发型肺结核比例高,占93.6%;(2)病变形态呈肺段大片状比例高,占16.2%,对照组呈斑片状比例高,占74.3%;(3)病变侵及4个肺野及以上占31.6%,对照组约占16.5%;少见部位多见,如下肺野结核,占12.8%,而对照组仅占0.9%;(4)以空洞病变为主比例并不高,占11.97%,对照组占32.1%。两组比较,均有显著性差异(均P<0.01)。结论西藏那曲地区肺结核X线表现有明显不同于南方沿海城市湛江的特点。
Objective To improve the understanding of tuberculosis X-ray findings in Nagqu Plateau in northern Tibet. Methods A total of 117 pulmonary tuberculosis cases were collected from July 1996 to September 1999 in Nagqu, Tibet. The first trimester of lung cancer were plain radiographs of tuberculosis. In the same period, 109 cases of tuberculosis of the same age in Zhanjiang, a coastal city, The authors used double-blind analysis of the two groups of X-ray performance, using χ2 test for statistical analysis. Results (1) The proportion of primary pulmonary tuberculosis was high, accounting for 7.69%, of which the proportion of adults was high, accounting for 4.3%. The proportion of secondary tuberculosis in control group was high, accounting for 93.6%. (2) Accounting for 16.2%, the control group showed a high proportion of patchy lesions, accounting for 74.3%; (3) lesions involving 4 lung fields and above accounted for 31.6%, control group accounted for 16.5%; rare site more common, Accounting for 12.8%, while the control group accounted for only 0.9%; (4) the proportion of empty lesions is not high, accounting for 11.97%, control group accounted for 32.1%. There was significant difference between the two groups (all P <0.01). Conclusion The X-ray manifestations of pulmonary tuberculosis in Naqu area of Tibet are obviously different from the characteristics of Zhanjiang in southern coastal city.
