[Clinical effects of follicle unit extraction transplantation combined with recombinant bovine basic fibroblast growth factor and minoxidil in the treatment of secondary cicatricial alopecia].

Objective: To explore the clinical effects of follicle unit extraction (FUE) transplantation combined with recombinant bovine basic fibroblast growth factor (rb-bFGF) gel and minoxidil tincture in treating secondary cicatricial alopecia (hereinafter referred to as cicatricial alopecia). Methods: A retrospective observational study was conducted. According to the different treatment methods, 50 cicatricial alopecia patients who met the inclusion criteria and only underwent FUE transplantation in the First Affiliated Hospital of Air Force Medical University from March 2013 to April 2017 were recruited into FUE alone group (26 males and 24 females, aged (28±13) years), and 50 cicatricial alopecia patients who met the inclusion criteria and underwent FUE transplantation+rb-bFGF gel during 1 to 14 days after surgery+minoxidil tincture during 15 to 180 days after surgery in this hospital from May 2017 to April 2020 were recruited into FUE+rb-bFGF+minoxidil group (32 males and 18 females, aged (27±9) years). Hair loss rates in post surgery month (PSM) 3 and 6, hair survival rates and satisfaction rates of patients in PSM 12, and the adverse effect rates of patients in the 2 groups within PSM 12 were observed and calculated. Data were statistically analyzed with chi-square test, Fisher's exact probability test, and independent sample t test. Results: In PSM 3 and 6, the hair loss rates of patients in FUE alone group were significantly higher than those in FUE+rb-bFGF+minoxidil group, respectively (t=70.850, 42.610, P<0.01). In PSM 12, the hair survival rate of patients in FUE+rb-bFGF+minoxidil group was (91.0±2.8)%, which was significantly higher than (80.9±6.9)% in FUE alone group (t=9.665, P<0.01). In PSM 12, 25 patients were very satisfied, 12 patients were fairly satisfied, 10 patients were slightly satisfied, 2 patients were not satisfied, and 1 patient was very unsatisfied in FUE alone group; 42 patients were very satisfied, 5 patients were fairly satisfied, and 3 patients were slightly satisfied in FUE+rb-bFGF+minoxidil group. The satisfaction rate of patients in FUE alone group was 74% (37/50), which was significantly lower than 94% (47/50) in FUE+rb-bFGF+minoxidil group (P<0.01). Within PSM 12, compared with those in FUE+rb-bFGF+minoxidil group, the incidence rates of folliculitis, abnormal growth direction, and skin necrosis in transplant site were not obviously changed in FUE alone group (P>0.05), while the incidence of scar in donor site was significantly higher (P<0.05). Conclusions: Compared with FUE transplantation alone, FUE transplantation combined with rb-bFGF and minoxidil can reduce the hair loss rate, improve the hair survival rate and the satisfaction rate of patients with cicatricial alopecia after FUE transplantation, with less adverse effects, thus are good for cicatricial alopecia treatment.目的： 探讨毛囊单位提取（FUE）移植术联合重组牛碱性成纤维细胞生长因子（rb-bFGF）凝胶和米诺地尔酊剂治疗继发性瘢痕秃发（下称瘢痕秃发）的临床效果。 方法： 采用回顾性观察性研究方法。根据不同治疗方法，将空军军医大学第一附属医院2013年3月—2017年4月接诊的符合人选标准的仅行FUE移植术的瘢痕秃发患者50例［男26例、女24例，年龄（28±13）岁］纳入单纯FUE组，将该单位2017年5月—2020年4月接诊的符合人选标准的行FUE移植术后1~14 d使用rb-bFGF凝胶+术后15~180 d使用米诺地尔酊剂的瘢痕秃发患者50例［男32例、女18例，年龄（27±9）岁］纳入FUE+rb-bFGF+米诺地尔组。观察并计算2组患者术后3、6个月的脱发率，术后12个月的毛发成活率和患者满意率，术后12个月内的不良反应发生率。对数据行χ2检验、Fisher确切概率法检验、独立样本t检验。 结果： 术后3、6个月，单纯FUE组患者脱发率均明显高于FUE+rb-bFGF+米诺地尔组（t=70.850、42.610，P<0.01）。术后12个月，FUE+rb-bFGF+米诺地尔组患者毛发成活率为（91.0±2.8）%，明显高于单纯FUE组的（80.9±6.9）%（t=9.665，P<0.01）。术后12个月，单纯FUE组患者中非常满意者25例、相当满意者12例、稍微满意者10例、不满意者2例、非常不满意者1例，FUE+rb-bFGF+米诺地尔组患者中非常满意者42例、相当满意者5例、稍微满意者3例；单纯FUE组患者满意率为74%（37/50），明显低于FUE+rb-bFGF+米诺地尔组的94%（47/50），P<0.01。术后12个月内，与FUE+rb-bFGF+米诺地尔组比较，单纯FUE组患者移植区毛囊炎、毛发方向异常、皮肤坏死发生率无明显变化（P>0.05），供区瘢痕发生率明显升高（P<0.05）。 结论： 与单独行FUE移植术相比，FUE移植术联合rb-bFGF及米诺地尔外用能降低瘢痕秃发患者FUE移植术后脱发率，提高术后毛发成活率及患者满意率，且不良反应少，利于瘢痕秃发的治疗。.
