摘  要:目的探讨脉络膜黑色素瘤中侵袭与转移相关因子缝隙连接蛋白43(Cx43)、上皮型钙黏附分子(E—eadherin)、磷脂酰肌醇-3激酶(P13K)及结缔组织生长因子(CTGF)的表达及意义。方法实验研究。采用免疫组织化学法检测27例脉络膜黑色素瘤组织及15例色索痣组织中Cx43、E.cadherin、P13K及CTGF的表达,并与临床病理资料做对照分析,采用χ2检验比较各因子表达阳性率的差异。结果Cx43、E.cadherin、P13K及CTGF蛋白在脉络膜黑色素瘤中的表达阳性率分别为74.07%(20/27),44.40%(12/27),74.07%(20/27)和66.67%(18/27),在色素痣中的表达阳性率分别为33.33%(5/15),86.67%(13/15),33.33%(5/15)和20.00%(3/15),Cx43、P13K及CTGF蛋自在脉络膜黑色素瘤中的表达较色素痣增加,差异有统计学意义(χ2=5.060,P=0.024;)(χ2=5.060,P:0.024;χ2=6.637,P=0.010)。E.eadherin蛋白在脉络膜黑色素瘤中的表达较色素痣降低,差异有统计学意义(χ2=5.490,P=0.019)。Cx43蛋白在不同组织学类型的脉络膜黑色素瘤中表达阳性率不同:梭形细胞型为40%(4/10),混合型88.89%(8/9),类上皮型为100%(8/8),差异有统计学意义(χ2=9.874,P=0.007)。P13K蛋白在不同大小的脉络膜黑色素瘤中表达阳性率不同:小肿瘤为42.86%(3/7),中肿瘤为75%(9/12),大肿瘤为100%(8/8),差异有统计学意义(χ2=6.357.P=0.042)。Cx43、E—eadherin、P13K及CTGF蛋白在未累及巩膜的脉络膜黑色素瘤中的表达阳性率分别为50.00%(6/12),83.33%(10/12),50.00%(6/12)和41.66%(5/12),在累及巩膜的脉络膜黑色素瘤中的表达阳性率分别为93.33%(14/15),40.00%(6/15),93.33%(14/15)和86.67%(13/15),Cx43、P13K及CTGF蛋�Objective To investigate the expression of factors related to invasion and metastasis in choroidal melanoma and to determine their relationships with malignant features. Methods The expression of Connexin43 ( Cx43 ), epithelial cadherin ( E-cadherin), phosphatidylinositol 3-kinase (PI3K) and connective tissue growth factor (CTGF) in choroidal melanoma and nevi were detected by immunohistochemistry, and the correlation between these factors and clinicopathological features were analyzed. Results Positive rates of Cx43, E-cadherin , PI3K and CTGF were 74.07% (20/27), 44. 4% (12/27), 74. 07% (20/27) and 66. 67% (18/27) in choroidal melanoma tissues, respectively; and 33.33% (5/15), 86.67% (13/15), 33.33% (5/15) and 20.00% (3/15) in the nevi tissues, respectively. There were significant differences in the expression of these markers between the two groups (χ2 =5.060, P=0.024;χ2 =5.490, P=0.019;χ2 =5.060, P=0.024; χ2 =6.637, P=0.010). The expression rates of Cx43 protein were 40% (4/10), 88.89% (8/9) and 100% (8/8) in spindle, mixed and epithelioid cell type, respectively. The expression of these data was related to histological type ( χ2 = 9. 874,P =0. 007). The expression rates of PI3K protein were 42. 86% (3/7), 75% (9/12) and 100% (8/8), in small, medium and large tumors, respectively, and their expression were co-related to the tumor size (X2 =6. 357,P =0. 042). Positive rates of Cx43, E-cadherin, PI3K and CTGF were 50% (6/12), 83.33% ( 10/12 ), 50% ( 6/12 ) and 41.66% ( 5/12 ), respectively, in choroidal melanoma tissues without sclera invasion and were 93.33% ( 14/15 ), 40% ( 6/15 ), 93.33% ( 14/15 ) and 86.67% (13/15), respectively, in choroidal melanoma tissues with violation involved the sclera. There were significant differences of the expression of these markers between the two groups ( χ2= 4. 457, P = 0. 016 ; χ2 =3.546, P =0.028;χ2=4.457, P =0.016; χ2=4.218, P=0.019). Conclusio
