摘  要:目的分析T淋巴细胞、白细胞介素-2(IL-2)、可溶性白细胞介素-2受体(sIL-2R)在结核性胸膜炎患者血清与胸腔积液中的差异,探讨其在结核性胸膜炎免疫机制中的作用。方法应用夹心酶联免疫吸附测定法(EusA)分别检测2010年6月至2011年12月在上海市肺科医院住院诊断为初治结核性胸膜炎并符合纳入标准的150例患者的外周血及胸腔积液中IL-2、SIL-2R的浓度;应用流式细胞仪分别检测150例结核性胸膜炎患者外周血及胸腔积液中的T淋巴细胞比率。采用SPSS16.0统计软件进行统计分析,外周血与胸腔积液检验结果比较采用配对t检验。结果(1)结核性胸膜炎患者胸腔积液中的CD3’、CD4’T淋巴细胞比率[(85.11±7.70)%、(55.67±12.94)%]较外周血[(70.91±10.33)%、(42.87±11.12%)]升高(P=9.846,P=0.03;t=-7.455,P=0.001),而CD8+T淋巴细胞比率胸腔积液中[(17.92±7.63)%]较外周血E(22.74±6.78)%]减少(t=4.372,P=0.012),故胸腔积液中的CD4+/CD8+比值(3.77±2.07)较外周血(2.13±1.16)明显升高(t=-6.542,P=0.001)。(2)结核性胸膜炎患者胸腔积液中IL-2、SIL-2R浓度E(68.55±41.40)pg/ml、(1672.25±713.75)pmol/L]较相应的外周血浓度[(32.97±32.30)pg/ml、(193.89±87.30)pmol/I。]明显升高(t=-7.282,P=0.000;t=-15.783,P=0.000)。(3)胸腔积液中的IL-2(68.55±41.40)pg/ml比外周血(32.97±32.30)pg/ml升高(37.78±34.86)pg/ml,约为外周血的2.079倍;胸腔积液中的sIL-2R(1672.25±713.75)pmol/L比外周血(193.89±87.30)pmol/L升高(1477.53±682.29)pmol/L,约为外周血的8.625倍。sIL-2R比IL-2在胸腔积液中上升更快,两者倍数的比较差异有统计学意义(Z=--4.283,P=0.000)。结论(1)CD3+、CD4+T淋巴细胞Objective To analyze the differences of T lymphocytes, interleukin-2 (IL-2), soluble interleukin- 2 receptor (sIL-2R) between in the sera and pleural effusions of patients with tuberculous pleurisy, and to explore the immune mechanism of tuberculous pleurisy. Methods Sandwich enzyme-linked immunosorbent assay (ELISA) were used to detect the IL-2, sIL-2R in peripheral bloods and pleural effusions of 150 patients, who were hospitalized in Shanghai Pulmonary Hospital from June 2010 to December 2011, and diagnosed as tuberculous pleu- risy of initial treatment, meeting the inclusion criteria. The ratios of T lymphocytes of peripheral blood and pleural effusion were detected in these 150 tuberculous pleurisy patients with the flow cytorneters. Statistical analysis was performed with SPSS 16.0 statistical software. Using paired samples statistics (t test) to compare the test results of peripheral blood and pleural fluid. Results (1) Of the patients with tuberculous pleurisy, the ratios of CD3+ and CIM+ T cells in pleural effusions( (85.11±7.70)%, (55.67±12.94)%) significantly higher than those in peripheral bloods ((70.91±10.33)%,(42. 87±11.12)%)(t=-9. 846, P=0. 03; t=-7. 455, P=0. 001). While the ratio of CD8+ T cells in pleural fluid (( 17.92± 7.63) ) significantly lessthan that in peripheral blood (( 22.74 ± 6.78) ) (t = 4. 372, P = 0. 012). The ratio of CI)4+/CD8+ in pleural effusion (3.77 ± 2.07) significantly higher than that in peripheral blood(2.13±1.16)(t=-6. 542, P=0. 001). (2) The concentrations of IL-2, sIL-2R in pleurisy fluids( ( 68. 55 ± 41.40) pg/ml, ( 1672.25± 713. 75) pmol/L) were significantly higher than those in the peripheral bloods from the patients with tuberculous pleurisy ( (32.97±32.30) pg/ml, (193.89±87.30) pmol/L) (t=-7. 282, P=0. 000; t=-15. 783, P=0. 000). (3) The level of IL-2 in pleural effusions((68. 55_+41.40)pg/ml) was 2. 079 times high
