To observe serum TGF-beta1 and TNF-alpha in silicosis patients and workers exposed to silica dust to study the role of TGF-beta1 and TNF-alpha in the development of silicosis.
One hundred non-exposed workers were selected as control group, 200 workers exposed to silica dust for more than 1 year as exposed group, 32 suspected silicosis patients (originally diagnosed as 0+) as observing group, 130 silicosis patients were as silicosis group. Serum TGF-beta1 and TNF-alpha in each group were determined with ELISA.
Serum TNF-alpha in exposed group [(47.86 +/- 16.52) pg/ml], observing group [(109.11 +/- 31.08) pg/ml], silicosis group [(216.35 +/- 51.03) pg/ml] were significantly higher than that in control group [(6.90 +/- 2.24) pg/ml] (P < 0.01); Silicosis group and observing group were also higher than exposed group (P < 0.01, P < 0.05). Compared with control group [(23.28 +/- 12.24) pg/ml] and exposed group [(29.31 +/- 14.52) pg/ml], serum TGF-beta1 in silicosis group was much higher (P < 0.01).
TGF-beta1, and TNF-alpha were essential in the development of silicosis, so the detection of TGF-beta1 and TNF-alpha in peripheral blood was very useful for occupational health surveillance and early diagnosis of silicosis.
观察矽肺患者及接触矽尘工人血清转化生长因子β1(TGF-β1)和肿瘤坏死因子α(TNF-α)水平,探讨TGF-β1和TNF-α在矽肺发生发展中的作用。
选取100名未接触者作为对照组,200名接触矽尘1年以上工人作为接触组,32名疑似矽肺患者(原诊断为0+)作为观察组,130名矽肺患者作为矽肺组。采用酶联免疫吸附测定法(ELISA)检测各组血清TGF-β1和TNF-α水平。
接触组血清TNF-α水平为(47.86±16.52)pg/ml,观察组为(109.11±31.08)pg/ml,矽肺组为(216.35±51.03)pg/ml,均显著高于对照组的(6.90±2.24)pg/ml(P<0.01);矽肺组和观察组也高于接触组(P<0.01,P<0.05)。矽肺组血清TGF-β1水平较对照组的(23.28±12.24)pg/ml和接触组的(29.31±14.52)pg/ml显著升高(P<0.01)。
TGF-β1和TNF-α在矽肺发生发展过程中起重要作用,因此检测外周血中TGF-β1和TNF-α水平对职业健康监护及矽肺的早期诊断具有重要意义。
