          摘  要  目的  基于Toll样受体4(TLR4)/髓系分化初级反应蛋白88(MyD88)信号通路,探讨黄芪颗粒对脂溢性脱发小鼠毛发生
          长的影响及潜在机制。方法  将雄性小鼠随机分为对照组、模型组、抑制剂组(0.3 mg/kg 的 TLR4 抑制剂 TAK-242)、黄芪颗粒组
         (1.0 g/kg)、黄芪颗粒+激活剂组(1.0 g/kg黄芪颗粒+2.5 mg/kg的TLR4激活剂脂多糖),每组12只。除对照组外,其余各组小鼠均
          采用背部涂抹松香-石蜡混合物及皮下注射丙酸睾酮的方式构建脂溢性脱发小鼠模型。造模后,各组小鼠灌胃并腹腔注射相应药
          液或(和)生理盐水,每天1次,持续20 d。比较各组小鼠的皮肤颜色转变时间、毛发长出时间;末次给药后,检测各组小鼠的新生
          毛发长度、血清中免疫因子[γ干扰素(IFN-γ)、白细胞介素4(IL-4)]和性激素[睾酮(T)、双氢睾酮(DHT)]水平以及背部皮肤组织中
          毛发生长因子[胰岛素样生长因子1(IGF-1)、血管内皮生长因子(VEGF)、转化生长因子β1 (TGF-β1 )]水平,观察其毛囊组织病理改
          变及细胞凋亡情况,检测其背部皮肤组织中 TLR4、MyD88 蛋白的表达情况。结果  与对照组比较,模型组小鼠毛囊细胞大小不
          一、排列紊乱,黑色素明显减少;其皮肤颜色转变时间,毛发长出时间,IFN-γ、T、DHT、TGF-β1水平,毛囊细胞凋亡率和 TLR4、
          MyD88蛋白的表达均显著延长/升高/上调,新生毛发长度、毛囊数和IL-4、IGF-1、VEGF水平均显著缩短/减少/降低(P<0.05)。与
          模型组比较,黄芪颗粒组和抑制剂组小鼠毛囊组织形态明显恢复,上述定量指标均显著改善(P<0.05),且两者作用相当(P>
          0.05)。TLR4激活剂可显著逆转黄芪颗粒对脂溢性脱发小鼠上述指标的改善作用(P<0.05)。结论  黄芪颗粒可调节脂溢性脱发
          小鼠的免疫功能,减少毛囊细胞凋亡,促进毛发生长;上述作用可能与抑制TLR4/MyD88信号通路激活有关。

          Dermatology, Huangshi Central Hospital, Hubei Huangshi 435000, China)

          ABSTRACT   OBJECTIVE To investigate the effects and underlying mechanism of Huangqi granules on hair growth in mice with
          seborrheic  alopecia  based  on  Toll-like  receptor  4 (TLR4)/myeloid  differentiation  primary  response  protein  88 (MyD88)  signaling
          pathway. METHODS Male mice were randomly divided into control group, model group, inhibitor group (treated with 0.3 mg/kg
          TLR4 inhibitor TAK-242), Huangqi granules group (treated with 1.0 g/kg Huangqi granules) and Huangqi granules+activator group
         (treated with 1.0 g/kg Huangqi granules combined with 2.5 mg/kg TLR4 activator lipopolysaccharide), with 12 mice in each group.
          Except for the control group, the seborrheic alopecia model of mice in other groups was induced by applying rosin-paraffin mixture
          on  the  back  and  injecting  testosterone  propionate  subcutaneously.  After  modeling,  mice  in  each  group  were  given  intragastric
          administration and intraperitoneal injection of corresponding drugs or (and) normal saline once a day for 20 consecutive days. The
          time  of  skin  color  transition  and  hair  emergence  time  were  compared  among  those  groups. After  the  last  medication,  the  length  of
          newly-grown  hair,  serum  levels  of  immune  factors  [interferon-γ (IFN-γ),  interleukin-4 (IL-4)]  and  sex  hormones  [testosterone
         (T),  dihydrotestosterone (DHT)],  as  well  as  the  levels  of  hair  growth  factors  [insulin-like  growth  factor  1 (IGF-1),  vascular
          endothelial growth factor (VEGF), transforming growth factor-β1 (TGF-β1 )] in the dorsal skin tissue were measured in each group.
          Pathological  changes  and  cell  apoptosis  of  hair  follicle  tissue  were  observed,  and  the  protein  expressions  of  TLR4  and  MyD88  in
          the  dorsal  skin  tissue  were  detected.  RESULTS  Compared  with  the  control  group,  hair  follicle  cells  in  the  model  group  were
          irregular  in  size,  disordered  in  arrangement,  and  showed  a  significant  reduction  in  melanin  content.  The  time  of  skin  color
          transition, hair emergence time, the levels of IFN-γ, T, DHT and TGF-β1, the apoptosis rate of hair follicle cells, as well as the
          protein  expressions  of TLR4  and  MyD88  in  the  model  group  were  significantly  prolonged/increased/up-regulated,  while  the  length
          of  newly-grown  hair,  the  number  of  hair  follicles,  and  the  levels  of  IL-4,  IGF-1  and VEGF  were  significantly  shortened/reduced/
          decreased (P<0.05).  Compared  with  the  model  group,  the  morphological  structure  of  hair  follicle  tissue  in  the  Huangqi  granules
                                                             group  and  inhibitor  group  was  significantly  restored,  and  the
