Methods： The BALB/c mice were randomized into a normal group, a control group, a roller-needle（RN） group, a mild plum-blossom needle（MP） group, and a heavy plum-blossom needle（HP） group. An area of hair was removed by external application of 8% sodium sulfide on BALB/c mice. The hair regrowth, hair follicle changes, and local inflammatory factor changes after cutaneous acupuncture were observed. Results： After treated with sodium sulfide, the hair was completely removed, the local hair follicles reached the catagen phase, and the expressions of interleukin（IL）-1α, IL-1β, IL-2, tumor necrosis factor（TNF）-α, interferon（IFN）-γ, and IL-17 were increased. Mice intervened by RN achieved the same hair growth rating as the controls but with thicker hair shafts; mice in the MP group had incomplete and uneven hair growth but thicker hair shafts; mice in the HP group didn＇t show hair growth. Pathological analysis revealed significant inflammatory infiltration into the local follicle bulbs and increased catagen-phase follicles in the control group, while RN and MP groups showed significantly increased anagen-phase follicles, coarser individual hairs, and obvious hair shafts. Meanwhile, most of the hair follicles in the HP group were in telogen phase and showed obvious surrounding inflammatory infiltration. RN, MP, and HP significantly down-regulated the increased IL-2, IL-1α, IL-1β, TNF-α, and IFN-γ levels（P〈0.05）, but didn＇t notably affect the increased CD34 expression（P〈0.05）. Conclusion： Cutaneous acupuncture with heavy stimulation intensity can inhibit hair growth in hair removal mice, while RN, with the lightest stimulation intensity, is unlikely to affect hair growth but may make hair shafts thicker and follicles larger.展开更多
