Résumé
Seborrheic alopecia is a chronic dermatological disease caused by multiple factors. It occurs frequently in young and middle-aged men aged 20-30 years. The main clinical manifestations are greasy hair， itching， excessive dandruff， receding hairline， sparse hair on the top of the head， and progressive hair loss in the frontotemporal area. Seborrheic alopecia is not fatal， but it affects the appearance of patients， seriously harming their self-esteem and bringing great psychological distress to them. The Wnt/β-catenin signaling pathway widely exists in multicellular eukaryotes and is a basic growth regulatory pathway which regulates cell proliferation and differentiation， maintains stem cells activity and organ homeostasis， and affects cell migration. At present， it has been reported in China and abroad that Wnt/β-catenin signaling pathway is closely related to the occurrence and development of seborrheic alopecia and the action mechanism of drugs. Traditional Chinese medicine （TCM） has multi-component， multi-target， and multi-pathway advantages， and it can promote the formation of hair follicle laminae， the proliferation and differentiation of hair follicle stem cells， and the periodic changes in hair follicles by regulating the Wnt/β-catenin signaling pathway， thereby alleviating seborrheic alopecia. This article reviewed the relationship of Wnt/β-catenin signaling pathway and its key target protein factors with seborrheic alopecia to clarify the important role of Wnt/β-catenin signaling pathway in seborrheic alopecia. At the same time， the TCM that targeted the Wnt/β-catenin signaling pathway to relieve seborrheic alopecia were summarized， so as to provide reference for the treatment of seborrheic alopecia and further development of new drugs.
Résumé
Objective To investigate the therapeutic effect of dense-packing auto hair grafting technique on the restoration of seborrheic alopecia. Methods With local anesthesia, a scalp strip was harvested from the back of the head. Under operating microscope (Various graft was created from the scalp strip, including micro-grafts with 1-2 hairs, mini-grafts with 3-4 hairs and sliver graft with 5-6 hairs. In the alopecia recipient area, micro slots were made with a small triangle-edged needle for the micro-grafts,mini slits were made with mini blade for the mini-grafts and foramen ovale were made with a slot punch. The grafts were then implanted into these holes. Results 32 cases of seborrheice alopecia were treated with the above mentioned technique from March 2007 to July 2009. Postoperative following up for 12-24 month showed that the grafted hairs were growing well with average 90 % survival of the hair. 81 % of the patients obtained satisfactory results with only one stage operation. Six patients needed the second operation to improve the appearance. All of the patients were satisfied with the appearance. Conclusions The dense-packing hair grafting technique with various grafts not only saves time of operation, but also obtains dense grafted hair and well appearance. The results are satisfactory to most patients with only one stage operation.
