目的探讨High mobility group A2protein(HMGA2)的表达对非小细胞肺癌生长、转移的影响,与临床病理参数和细胞增殖的关系。方法应用免疫组化法检测38例非小细胞肺癌组织(23例鳞癌,15例腺癌)及癌旁的正常肺组织标本中HMGA2和Ki-67的表达...目的探讨High mobility group A2protein(HMGA2)的表达对非小细胞肺癌生长、转移的影响,与临床病理参数和细胞增殖的关系。方法应用免疫组化法检测38例非小细胞肺癌组织(23例鳞癌,15例腺癌)及癌旁的正常肺组织标本中HMGA2和Ki-67的表达。结果HMGA2和Ki-67在癌旁的正常肺组织中均不表达,而在肺癌组织中的表达阳性率分别为39.47%、44.74%,二者在肺癌组和癌旁的正常肺组织组之间差异有显著性(P<0.05)。HMGA2的表达在伴淋巴结转移的肺癌组织明显高于不伴有淋巴结转移的肺癌组织(P<0.05),而与其他临床病理参数包括肿瘤的分化程度、肿瘤大小和TNM分期以及细胞增殖指标Ki-67之间没有相关性。结论本研究显示HMGA2在非小细胞肺癌组织中异常表达,可能与肺癌的发生和进展有关。展开更多

The ultra-structural change was observed by electron microscopy. The number of cells positive for SPA was by immunohistochemically measured. The mRNA expression in the lung tissues was determined by reverse transcription polymerase chain reaction (RT-PCR). The number of cells positive for SPA of the S group (0.52±0.05) was lower than that of the N group (0.72±0.06) (P〈0.05). The levels of mRNA of SPA in the lung tissues of the S group (0.3522±0.0512) was significantly lower than that of the N group (0.4432± 0.05628) (P〈0.05). It is concluded that cigarette smoke alone decreased the level of SP-A and that might have an important effect on surfactant metabolism and the host defense functions of surfactant in the peripheral airways, which might play a crucial role in the development of chronic obstructive lung disease.展开更多
