摘要 目的 观察翼状胬肉的增殖状况及用药后的变化。方法 将54 例翼状胬肉术前患者随机分为3 组:Ⅰ组18 例为未用药组,Ⅱ组16 例术前局部应用氟美松,Ⅲ组20 例术前局部应用高三尖杉酯碱加氟美松。采用免疫组化方法对手术切除的翼状胬肉标本进行增殖细胞核抗原(proliferating cellnuclear antigen ,PCNA) 检测。结果 未用药组( Ⅰ组)PCNA 阳性率为(1153 ±362)% ,氟美松组( Ⅱ组) 为(1028 ±418)% ( P> 005) ,高三尖杉酯碱加氟美松组( Ⅲ组) 为(559±382) % ( P< 001) 。< 60 岁的进行型患者PCNA阳性率高于≥60 岁的静止型患者。结论 翼状胬肉组织中存在细胞增殖及PCNA表达,术前应用高三尖杉酯碱加氟美松可抑制PCNA 表达及术后翼状胬肉的复发。 Objective To study the proliferating status of pterygium and the drug′s influence on it. Method Fifty four patients with pterygium were randomly assigned into three groups: Before the surgical excision of the pterygium, group 1 (18 cases) had received no drug, group 2 (16 cases) received local dexamethasone treatment, and group 3 (20 cases), local homoharringtonine and dexamethasone treatment. The immunohistochemical study on proliferating cell nuclear antigen (PCNA) was performed on the surgical specimens of the pterygium. Result The PCNA positive rate was (11.53±3.62)% in the untreated group, (10.28± 4.18)% in the dexamethasone group ( P >0.05), and (5.59±3.82)% in the homoharringtonine and dexamethasone group ( P <0.01). The PCNA positive rate was higher in the younger patients (<60 years) with progressive type of the disease than that in the elder patients (≥60 years) with quiet type. Conclusions There are cell proliferation and PCNA expression in pterygium. The homoharringtonine and dexamethasone local injection before the excision of pterygium can effectively decrease the PCNA expression and recurrence rate of pterygium. Local injection of dexamethasone before surgical excision has no influence on the PCNA expression of pterygium.
