摘  要:目的探讨活动性肺结核患者外周血Y-干扰素释放分析T-SPOT.TB测定与不同痰结核菌分级及肺部病变程度的关系。方法采用T-SPOT.TB技术、根据斑点形成细胞数(SFCs)检测77例初治活动性肺结核患者、14例肺部非结核病变者和12例健康对照者外周血结核抗原特异性的IFN-Y分泌细胞数,结合痰细菌学和影像学检查进行分析。结果肺结核组T-SPOTTB的6KD早期分泌抗原靶点抗原孔(A孔)SFCs为55.00(21.00~102.50),10KD培养滤过蛋白抗原孔(B孔)SFCs为65.D0(20.50~152.50),显著高于非肺结核组和健康对照组(P〈0.05)。肺结核痰菌分级4+组A孔SFCs为1700(400~31.50),显著低于痰菌阴性组的82.50(36.25~10375)、1~9条组的65.00(28.50~102.50)、1+组的8000(32.75~12625)、2+组的90.OO(27.50~145.00)和3+组的45.00(1800~150.00)(U=41.5,17.O,2215,26.5,30.5;Z=-2.745,-2.980,-3.325,-2.975,-2.377;均P〈0.05);痰菌分级4+组B孔SFCs为21.00(250~42.50),显著低于痰菌阴性组的85.00(9.00~195.00)、1~9条组的102.50(71.25~193.75)、1+组的92.50(33.25~165.00)、2+组的70.00(34.00~162.50)和3+组的6000(20.00~140.00),(U=55.0,100。28.5,285,36.5;Z=-2.150,-3.413,-3.304,-2.874,-2.031;均P〈0.05)。A孔和B孔SFCs在不同病变范围的肺结核患者之间比较差异有统计学意义(F=7.463,3.205;P〈005),病变范围重度组A孔SFCs为(31.95±51.09),低于轻度组的(99.22±6909)和中度组(72.43±49.31)(t=3.520,2,845;均P〈0.05);病变范围重度组B孔SFCs为f49.42±87.73),低于轻度组(112.39±75.20)和中度组(104.00±9430)(,=2505,2.080;均P〈0.05)。肺结核空洞组和无空洞组比较,A孔和B孔SFCs均差异无Objective To determine the relationship between the interferon-y release assays measured by T-SPOT.TB in peripherat blood and mycobacterium tuberculosis smear grading and radiographic extent of disease in patients with active pulmonary tuberculosis. Methods T-SPOT.TB assay was used to determine spot-forming cells (SFCs) formed by T-cell which release interferon-y when stimulated by Mycobaeterium tuberculosis-specific antigens in 77 patients with active tuberculosis, 14 case controls with non-tuberculosis lung diseases and 12 healthy controls, then the SFCs were compaired with bacteriological and radiographic presentations in new cases of pulmonary tuberculosis. Results The SFCs of A hole in response to ESAT-6 and B hole in response to CFP-10 in pulmonary tuberculosis group were 55.00(21.00-102.50) and 65.00(20.50-152.50), respec- tively,which were all significantly higher than those in controls (P〈0.05). The SFCs of A hole and B hole in pulmonary tuberculosis patients with mycobacterium tuberculosis grade of 4+ were 17.00(4.00-31.50)and 21.00(2.50-42.50), respectively. The SFCs of A hole in pulmonary tuberculosis patients with mycobacterium tuberculosis grade of negative, 1-9institias, 1+, 2+ and 3+ were 82.50(36.25-103.75),65.00(28.50-102.50),80(32.75-126.25),90.00(27.50-145.00) and 45.00(18.00-150.00), and the SFCs of B hole were 85.00 (9.00-195.00),102.50 (71.25-193.75),92.50(33.25-165.00), 70.00(34.00-162.50) and 60.00(20.00-140.00), re- spectively. The SFCs of A hole in pulmonary tuberculosis patients with mycobacterium tuberculosis grade of 4+ were significantlyhigher than thoses in patients with grade of negative, 1-9 institias, 1+, 2+ and 3+ (U=41.5, 17.0, 22.5, 26.5, 30.5;Z=-2.745, -2. 980, -3.325, -2.975, -2.377; P〈0.05), so as the SFCs of B hole (U=55.0, 10.0, 28.5, 28.5, 36.5;Z=-2.150, -3.413, -3.304, -2. 874, -2.031; P〈0.05). There were statistical significance about the SFCs of A hole and B hole compared wi
