[目的]探讨胸膜孤立性纤维瘤(solitary fibrous tumor of the pleura,SFTP)的临床特点及治疗方法。[方法]回顾性分析大连医科大学附属第二医院胸外科2006年-2009年收治的10名胸膜孤立性纤维瘤患者的临床资料,10例患者均行手术切除肿瘤,其中2例术前行介入栓塞治疗,术后肿瘤组织行病理检查及免疫组化分析。[结果]病理检查提示肿瘤组织主要由梭形细胞和胶原纤维组成,免疫组化分析CD34、Vimentin、Bc1-2均为阳性表达,CD99部分阳性表达(2例)。10例患者中,术前行介入栓塞治疗的2名患者术中出血明显减少;术后病理诊断均为胸膜孤立性纤维瘤,术后随访8个月-2年,效果良好迄今为止,未发现肿瘤转移复发。[结论]手术是目前治疗SFTP的最佳方法,术前行介入治疗能够有效地减少术中出血。免疫组化对该病的诊断具有重要价值。
OBJECTIVE: To investigate the relationship between the expression of glucose regulated protein 94 (GRP94) at the level of mRNA and protein in vivo and in human lung cancer. METHODS: RT-PCR, immunohistochemistry and/or Western blot were used in 54 cases of lung cancer tissues and corresponding normal lung tissues. RESULTS: There was a significant overexpression of GRP94 mRNA and protein in lung cancer tissues as compared with lung normal tissues. In lung cancer tissue, the relative level of GRP94 mRNA as evaluated by RT-PCR was 3.48 +/- 2.06, the level of GRP94 protein as evaluated by immunohistochemistry was + + to + + +, and by Western blot was 256.7 +/- 80.6. In lung normal tissue, the relative level of GRP94 mRNA was 2.01 +/- 1.83, the level of GRP94 protein was + to + + and 108.1 +/- 42.3. The differences in expression of GRP94 between the two tissues were significant (P
