【摘要】 目的:了解雄激素受体(AR)在雄性激素源性脱发(AGA)患者顶部表皮、毛囊、皮脂腺、汗腺中的表达情况。方法:选取26例雄性激素源性脱发患者顶部、枕部以及10例非脱发者的顶部头皮标本,用免疫组织化学检测表皮、毛囊、皮脂腺、汗腺中AR的表达。结果:脱发患者头顶部毛囊、皮脂腺、汗腺AR表达均明显强于枕部和非脱发者枕部,差异均有统计学意义(P<0.05);脱发患者枕部毛囊、皮脂腺、汗腺AR表达与非脱发者顶部AR表达比较差异均无统计学意义(P>0.05);所有标本表皮中AR均为阴性。结论:AR在AGA患者头顶部毛囊、皮脂腺、汗腺的高表达,可能是AGA重要原因之一。

【Abstract】 Objective:To investigate AR expression in the top of epidermis, hair follicle and sebaceous gland, sudoriferous gland.Method:The top and the occipital scalp of AGA patients (n=26) and the top scalp of non-alopecia people (n=10) as specimens were obtained, and AR expressions in the epidermis, hair follicle and sebaceous gland, sudoriferous gland were studied by immunohistochemistry method.Result:AR expressions of hair follicle, sebaceous gland, sudoriferous gland on the top of AGA patients were stronger than the occipital of AGA patients and the top of non-alopecia(P<0.05); AR expressions of hair follicle, sebaceous gland, sudoriferous gland in the occipital of AGA patients had no significant difference with the top of non-alopecia(P>0.05). All samples were negative for AR in epidermis.Conclusion:AR expressions on the top of hair follicle and sebaceous gland, sudoriferous gland in AGA patients may be one of the key factors leading to AGA.

雄性激素源性脱发(Androgenetic alopecia,AGA)是临床最常见的脱发性疾病,表现为前额发际逐渐后退,顶部头发逐渐稀疏脱落。脱发不仅严重影响患者的外在形象,而且从心理上也给患者带来了无尽的烦恼,越来越受到人们的重视[1]。国内流行病学调查显示,本病在我国男性的患病率为15.73%~19.75%,女性患病率为2.73%~4.69%,其病因还不完全清楚,治疗也一直是个棘手的问题[2-3]。为探索AGA的发病原因,从而为防治提供依据,笔者对26例雄性激素源性脱发患者顶部和枕部头皮以及10例非脱发者顶部头皮标本,采用免疫组化法检测雄性激素受体(androgen receptor,AR)在表皮、毛囊、皮脂腺、汗腺的表达水平,现报告如下。
1 资料与方法
1.1 一般资料 选取2013年1月-2014年1月本院皮肤科门诊就诊的AGA患者26例,均为男性,年龄2l~49岁,平均(30.38±2.25)岁,病程3个月~3年。选取本院神经外科手术的非脱发患者,共10例,均为男性;年龄20~48岁,平均(29.83±1.69)岁。两组研究对象的性别、年龄比较差异均无统计学意义(P>0.05),具有可比性。本……
