目的 探讨血小板衍化内皮细胞生长因子(PD-ECGF)、血管内皮生长因子(VEGF)与毛细血管瘤增生退化关系,为其治疗提供理论依据.方法 随机选取毛细血管瘤患儿40例为实验组,并据Mulliken标准分为增生期组(22例)及消退期组(18例),所有标本术后病理证实为毛细血管瘤;另选同期包皮手术患儿8例为正常皮肤对照组.将标本固定、包埋,HE染色,免疫组化法检测血管瘤增生期、消退期及正常皮肤内皮细胞中PD-ECGF及VEGF表达,并检测血管内皮标志抗原CD34表达,计算各期血管瘤及正常皮肤微血管密度(MVD).应用SPSS 12.0 for windows统计软件分析处理.结果 增生期血管瘤、消退期血管瘤、正常皮肤PD-ECGF阳性率分别为95.45%(21/22)、77.78%(14/18)、37.50%(3/8);VEGF阳性率分别为86.36%(19/22)、66.67%(12/18)、37.50%(3/8);MVD为93.68 ±20.56、51.94±20.73、17.50 ±5.30.血管瘤不同分期之间,血管瘤与正常皮肤之间PD-ECGF、MVD差异均有统计学意义(P<0.05);血管瘤不同分期之间、增生期与正常皮肤之间,VEGF差异有统计学意义(P<0.05),消退期与正常皮肤之间VEGF差异无统计学意义(P>0.05);PD.ECGD、VEGF与MVD的表达均呈正相关.结论 PD-ECGF和VEGF在血管瘤增生期表达均高于消退期,两者相互协同作用,其表达水平与血管瘤增生退化密切相关;PD-ECGF可能通过表达胸苷磷酸化酶(TP)活性影响瘤体中微血管生成而发挥作用.
目的 探討血小闆衍化內皮細胞生長因子(PD-ECGF)、血管內皮生長因子(VEGF)與毛細血管瘤增生退化關繫,為其治療提供理論依據.方法 隨機選取毛細血管瘤患兒40例為實驗組,併據Mulliken標準分為增生期組(22例)及消退期組(18例),所有標本術後病理證實為毛細血管瘤;另選同期包皮手術患兒8例為正常皮膚對照組.將標本固定、包埋,HE染色,免疫組化法檢測血管瘤增生期、消退期及正常皮膚內皮細胞中PD-ECGF及VEGF錶達,併檢測血管內皮標誌抗原CD34錶達,計算各期血管瘤及正常皮膚微血管密度(MVD).應用SPSS 12.0 for windows統計軟件分析處理.結果 增生期血管瘤、消退期血管瘤、正常皮膚PD-ECGF暘性率分彆為95.45%(21/22)、77.78%(14/18)、37.50%(3/8);VEGF暘性率分彆為86.36%(19/22)、66.67%(12/18)、37.50%(3/8);MVD為93.68 ±20.56、51.94±20.73、17.50 ±5.30.血管瘤不同分期之間,血管瘤與正常皮膚之間PD-ECGF、MVD差異均有統計學意義(P<0.05);血管瘤不同分期之間、增生期與正常皮膚之間,VEGF差異有統計學意義(P<0.05),消退期與正常皮膚之間VEGF差異無統計學意義(P>0.05);PD.ECGD、VEGF與MVD的錶達均呈正相關.結論 PD-ECGF和VEGF在血管瘤增生期錶達均高于消退期,兩者相互協同作用,其錶達水平與血管瘤增生退化密切相關;PD-ECGF可能通過錶達胸苷燐痠化酶(TP)活性影響瘤體中微血管生成而髮揮作用.

Objective To explore the relation between the expressions of PD-ECGF and VEGF and the evolution of capillary hemangioma, so as to provide theoretical basis for treatment. Methods Fourty cases with capillary hemangioma, proved by pathologic method, were randomly selected and divided into proliferative(n = 22) and involuted groups(n = 18) , according to the Mulliken standard. 8 specimens from 8 children with prepuce operation were used as control group. All the specimens were fixed,embedded and underwent HE staining. The expression of PD-ECGF, VEGF and CD34 in endothelial cells were detected by immunohistochemistry. The microvessel-density (MVD) was also calculated. The results were analyzed by SPSS12. 0. Results The positive expression rates of PD-ECGF and VEGF were 95. 45% (21/22) and 86. 36% ( 19/22) in proliferative hemangioma, 77. 78% (14/18) and 66. 67% (12/18) in involuted hemangioma, 37. 50% (3/8) and 37.50% (3/8) in normal skin. MVD in proliferative and involuted hemangioma and normal skin was 93.68 ± 20.56, 51.94 ± 20.73 and 17.50 ± 5.30,respectively. There was a significant difference in PD-ECGF expression and MVD between the proliferative and involuted groups, or between the hemangioma and control groups ( P < 0.05). The VEGF was significantly different between the proliferative and involuted groups, or between the proliferative and control groups(P <0. 05) , but not between the involuted and control groups (P>0. 05). The expression of VEGF, PD-ECGD and MVD showed a positive relationship. Conclusions PD-ECGF and VEGF have a synergetic effect in the proliferation of micro-vessels. PD-ECGF may enhance the activity of thymidine phosphorylase. They play an important role in the proliferation and involution of hemangioma.
