Abstract： 尿道下裂是小儿外科常见疾病,尿道成形术后常发生尿道狭窄,治疗后易复发,影响手术效果,这始终是小儿泌尿外科十分棘手的难题.尿道狭窄与尿道愈合过程中瘢痕形成有关,因此抑制尿道瘢痕形成的药物成为研究热点.近年来发现钒酸盐作为蛋白酪氨酸磷酸酶抑制剂,是促进愈合,抑制瘢痕的有效物质,Ehrlich等[1]研究了钒酸盐对皮肤伤口愈合作用,发现钒酸盐可提高皮肤愈合速度和质量,减少瘢痕形成.钒酸盐还可以抑制韧带成纤维细胞肌动蛋白(a-SMA)过表达,从而抑制瘢痕收缩[2-3].但钒酸盐在防治小儿尿道瘢痕中能否发挥作用值得深入研究,本研究利用人尿道瘢痕成纤维细胞体外培养的方法,观察钒酸盐对成纤维细胞胶原合成及a-SMA表达的影响.
