【摘要】:目的:探討VEGF的表達(dá)及微血管密度在翼狀胬肉的發(fā)生、發(fā)展過程中的意義。 方法:選取手術(shù)切除的翼狀胬肉標(biāo)本47例(進(jìn)行期,N=30,靜止期組,N=17),正常結(jié)膜標(biāo)本20例。采用免疫組化二步法,觀察了VEGF在翼狀胬肉中的表達(dá),利用CD31檢測了翼狀胬肉中微血管密度。 結(jié)果:翼狀胬肉中VEGF表達(dá)率為85.1%,正常結(jié)膜中表達(dá)率為20.0%,二者相比較差異有顯著的統(tǒng)計學(xué)意義(P0.01),在翼狀胬肉進(jìn)行期組中的表達(dá)率為96.7%,靜止期組中的表達(dá)率為64.7%,二者相比較差異有統(tǒng)計學(xué)意義(P0.05)。在翼狀胬肉Ⅰ、Ⅱ、Ⅲ度中表達(dá)率各為50.0%、87.5%、92.0%,三者相比較差異有統(tǒng)計學(xué)意義(P0.05)。在翼狀胬肉組中的MVD值為19.12±6.56,在正常結(jié)膜組中為4.60±1.53,兩者有顯著的統(tǒng)計學(xué)意義(P0.01)。在進(jìn)行期組中MVD值為19.60±6.78,在靜止期組中為9.58±2.52,差異有統(tǒng)計學(xué)意義(P0.05)。在翼狀胬肉I、II、III度組中MVD值為11.32±1.25、18.93±2.59、19.96±6.32,差異無統(tǒng)計學(xué)意義(P0.05)。在翼狀胬肉中VEGF表達(dá)與MVD值之間具有一致性,呈正相關(guān)(r=0.594,PO.05)。 結(jié)論:在翼狀胬肉中VEGF表達(dá)與MVD值呈正相關(guān),提示翼狀胬肉的發(fā)生、發(fā)展中新生血管的生成可能發(fā)揮重要的作用。

Methods: 47 cases of pterygium and 20 cases of normal conjunctiva were selected. The expression of VEGF in pterygium and microvessel density in pterygium were detected by CD31. Results: the expression rate of VEGF was 85.1 in pterygium, 20.0 in normal conjunctiva, and 96.7in pterygium group. The expression rate in static phase group was 64.7, the difference was statistically significant (P0.05). The expression rates of pterygium 鈪,
