摘要
目的探讨检测血清与胸腔积液中瘦素(LEP)、TNF-α、癌胚抗原(CEA)、C反应蛋白(CRP)和IL-6在鉴别诊断结核病与恶性肿瘤中的价值。方法抽取54例肺癌患者及41例结核患者胸腔积液与血清,采用ELISA和免疫比浊法分别检测胸腔积液和血清中LEP、TNF-α、CEA、CRP和IL-6含趋,正态分布数据采用£检验,非正态分布数据采用秩和检验。结果结核患者和肿瘤患者血清中LEP分别为(0.42±0.47)、(1.80±0.91)ng/mL,差异有统计学意义(t=9.666,P=0.0001);TNF-α分别为(30.88±24.72)、(59.83±30.93)pg/mL,差异有统计学意义(t=4.917,P=0.0001);CEA分别为(0.22±0.30)、(5.67±3.60)ng/mL,差异有统计学意义(t=11.074,P=0.00@1);IL-6分别为(146.48±54.90)、(20.51±11.62)pg/mL,差异有统计学意义(t=-14.449,P=0.0001);CRP分别为(32.78±22.43)、(37.80士16.74)mg/mL,差异无统计学意义(t=1.249,P=0.215)。结核患者和肿瘤患者胸腔积液中LEP分别为(0.69±0.65)、(4.33±2.16)ng/mL,差异有统计学意义(t=11.711,P=0.0001);TNF-α分别为(20.60±17.80)、(40.40±20.60)pg/mL,差异有统计学意义(t=4.926,P=0.0001);CEA分别为(0.10±0.17)、(4.02±2.49)ng/mL,差异有统计学意义(t=11.537,P=0.0001);IL-6分别为(87.80±48.40)、(9.30±5.50)pg/mL,差异有统计学意义(t=10.333,P=0.O001);CRP分别为(27.34±17.93)、(29.60±13.40)mg/mL,差异无统计学意义(t=0.709,P=0.102)。结论肿瘤患者胸腔积液与血清中LEP、TNF-α、CEA水平均高于结核病患者,而IL-6水平则相反,检测这些指标有助于结核病与肿瘤患者的鉴别诊断。
Objective To evaluate the significance of combined detection of leptin (LEP), tumor necrosis factor α (TNF-α), careino-embryonic antigen (CEA), C-reactive protein (CRP) and interleukin 6 (IL -6) in both serum and pleural effusion in differential diagnosis of tuberculosis and malignant tumor. Methods LEP, TNF-α, CEA, CRP and IL-6 levels in both pleural fluid and serum samples from 95 cases of pleural effusion (including 54 cases of malignant pleural effusion and 41 cases of tuberculous pleural effusion ) were detected by immunoturbidimetry and enzyme-linked immunosorbent assay (ELISA), respectively. The data with normal distribution and skewed distribution were analyzed by t test and rank sum test, respectively. Results In patients with tuberculosis and malignant tumor, significant difference was observed in serum LEP [(0.42±0.47) ng/mL vs (1. 80±0. 91) ng/mL, t=9.666, P= 0.0001], TNF-α[(30.88±24.72) pg/mLvs (59.83±30.93) pg/mL, t= 4.917, P= 0.0001], CEAE(0.22±0.30) ng/mL vs (5. 67±3. 60) ng/mL, t=11. 074, P=0. 00011 and IL-6 [146. 48±54. 90) pg/mL vs (20. 51±11. 62) pg/mL, t= -14. 449, P=0. 00011 levels. Serum CRP levels of patients with tuberculosis and malignant tumor were comparable [(32. 78±22. 43) mg/mL vs (37.80± 16. 74) mg/mL, t= 1. 249, P=0. 215]. In pleural effusion of the two groups (tuberculous pleural effusion vs malignant pleural effusion), LEP [(0.6.9±0.65) ng/mL vs (4.33±2.16) ng/mL, t= 11.711, P= 0.0001], TNF-α [(20. 60± 17.80) pg/mLvs (40.40±20.60) pg/mL, t= 4.926, P =0.0001], CEA [(0. 10±0. 17) ng/mL vs (4.02±2.49) ng/mL, t=11.537, P=0. 0001] and IL-6 [(87. 80±48. 40) pg/m: vs (9. 30± 5.50) pg/mL, t = -10.333, P = 0.0001] levels were significantly different, while CRP levels [(27.34±17. 93) mg/mL vs (29.60± 13.40) mg/mL, t= 0. 709, P = 0. 102] were comparable. Conclusion LEP, TNF-α, and CEA levels in both pleural effusion and serum samples from patients with m
