摘要: 目的 探讨肺结核患者的血清可溶性白介素-2受体(sIL-2R)、γ干扰素(IFN-γ)、肿瘤坏死因子α(TNF-α)、白介素-6(IL-6)的变化及意义。 方法 采用双抗体夹心ABC-ELISA法测定214例初治肺结核的血清中sIL-2R、TNF-α、IL-6、IFN-γ的水平。 结果 肺结核病人血清sIL-2R的检测结果各组平均值均高于正常,随着病灶范围增加sIL-2R的水平也增加;3~4肺野组与5~6肺野组sIL-2R水平明显高于1~2肺野组(P<0.01);痰菌阳性组sIL-2R水平明显高于阴性组(P<0.01)。肺结核病人血清TNF-α的检测结果显示1~2肺野组与3~4肺野组平均值均高于正常,随着病灶范围增加TNF-α的水平减少,5~6肺野组在正常范围,1~2肺野组TNF-α的水平明显高于5~6肺野组(P<0.01);无空洞组TNF-α平均值高于有空洞组(P<0.05)。肺结核病人的血清INF-γ的检测结果显示各组平均值均高于正常,其中5~6个肺野组比3~4肺野组高(P<0.05);痰菌阳性组比阴性组IFN-γ水平高(P<0.05)。 结论 不同肺结核患者外周血中sIL-2R、TNF-α、IFN-γ、IL-6水平存在着差异,这些细胞因子可能在结核病的发病中起着一定的作用。

Abstract: Objective To explore the change and value of sIL-2R, TNF-α, IFN-γ and IL-6 in the serum samples of patients with pulmonary tuberculosis.  Method The levels of sIL-2R, TNF-α, IFN-γ and IL-6 were measured using the sandwich ABC-ELISA method in 214 patients with pulmonary tuberculosis.   Result The levels of sIL-2R in sera in each group were higher than normal, and increased with lesion scope enlarged, in which the levels of sIL-2R in 3-4 lung field group and  5-6  lung field group were significantly higher than those in 1-2 lung field group(P<0.01). The levels of sIL-2R in the smear-positive group were significantly higher than those in smear-negative group(P<0.01).The levels of TNF-α in sera in 1-2 lung field group and 3-4 lung field group were higher than normal, and decreased with lesion scope enlarged. The levels of TNF-α in 1-2 lung field group were higher than those in 5-6 lung field group, which were normal (P<0.01). The levels of TNF-α in non-cavity group were higher than those in cavity group(P<0.05).The levels of INF-γ in sera in each group were higher than normal, and in 5-6 lung field group were higher than those in  3-4  lung field group(P<0.05). The levels of INF-γ in the smear-positive group were higher than those in smear-negative group (P<0.05).   Conclusion The levels of sIL-2R, TNF-α, IFN-γ and IL-6 in the serum samples of different patients with pulmonary tuberculosis were different.These cytokines may be play roles in the pathogenesis of tuberculosis.
