文摘目的探讨龙血竭联合氟尿嘧啶注射液对不同转化生长因子-β(Transforming growth factor-β,TGF-β)单核苷酸多态性瘢痕疙瘩患者的疗效。方法纳入2019年7月—2022年1月医院收治的瘢痕疙瘩患者240例,根据TGF-β单核苷酸多态分为野生组(野生型TGF-β)、突变组(突变型TGF-β),并将突变组分为亚组:rs747857组(rs747857型TGF-β)、rs1800469组(rs1800469型TGF-β)、rs2241716组(rs2241716型TGF-β)。使用氟尿嘧啶注射液单药治疗或血竭联合氟尿嘧啶注射液治疗5组患者。5组患者治疗前和首次治疗后12个月通过温哥华瘢痕量表(Vancouver scar scale,VSS)、瘢痕评估量表(Patient and observer scar assessment scale,POSAS)和皮肤病生活质量指数(Dermatologic quality of life index,DLQI)量表进行评分。结果与野生组比较,突变组、rs747857组、rs1800469组、rs2241716组TGF-βmRNA的表达水平均上升(P<0.05)。与野生组相比,单药治疗下突变组、rs1800469组和rs2241716组患者在治疗后VSS总评分、POSAS总评分均显著上升(P<0.05);而与单药治疗相比,联合治疗下突变组、rs1800469组和rs2241716组患者在治疗后VSS总评分、POSAS总评分均显著下降(P<0.05)。与野生组相比,rs2241716组患者在治疗后的DLQI量表评分均显著上升(P<0.05);而与单药治疗相比,联合治疗下rs2241716组患者在治疗后的DLQI量表评分均显著下降(P<0.05)。与野生组相比,rs1800469组和rs2241716组患者在治疗后的有效率显著下降(P<0.05);而与单药治疗相比,联合治疗下rs1800469组和rs2241716组患者在治疗后的有效率显著上升(P<0.05)。与野生组相比,突变组、rs1800469组和rs2241716组患者的首次显效及达到首次显效时氟尿嘧啶次数均延后(P<0.05);而与单药治疗相比,联合治疗下突变组、rs1800469组和rs2241716组患者的首次显效及达到首次显效时氟尿嘧啶次数均提前(P<0.05)。与单药治疗相比,联合治疗下野生组、突变组、rs747857组、rs1800469组、rs2241716组的总不良反应更少(P<0.05)。结论龙血竭联合氟尿嘧啶注射液对不同TGF-β单核苷酸多态性瘢痕疙瘩患者有较好的疗效,和较少的不良反应。
