ObjectiveTo systematically and objectively evaluate the therapeutic efficacy of comprehensive acupuncture treatment in managing wet age-related macular degeneration (ARMD), and to seek a standard acupuncture protocol for this disease, for promoting the application in clinic.MethodTotally 37 patients (67 eyes) were observed to compare the vision, Amsler grid and rating scale of quality of life for visual impairment before and after the 3-month treatment. The clinical efficacy was then evaluated. ResultThe vision and score of quality of life were significantly changed after intervention (P<0.05); according to Amsler grid, the total improved rate was 79.2% and the total effective rate was 77.6%; age and disease duration were negatively correlated with the therapeutic efficacy (P<0.05).ConclusionComprehensive acupuncture treatment can significantly improve the vision and quality of life in patients with wet ARMD, and the younger the patients and the shorter the disease duration, the higher the therapeutic efficacy.

Hair loss affects millions of people at some time in their life, and safe and efficient treatments for hair loss are a significant unmet medical need. We report that topical delivery of quercetin (Que) stimulates resting hair follicles to grow with rapid follicular keratinocyte proliferation and replenishes perifollicular microvasculature in mice. We construct dynamic single-cell transcriptome landscape over the course of hair regrowth and find that Que treatment stimulates the differentiation trajectory in the hair follicles and induces an angiogenic signature in dermal endothelial cells by activating HIF-1α in endothelial cells. Skin administration of a HIF-1α agonist partially recapitulates the pro-angiogenesis and hair-growing effects of Que. Together, these findings provide a molecular understanding for the efficacy of Que in hair regrowth, which underscores the translational potential of targeting the hair follicle niche as a strategy for regenerative medicine, and suggest a route of pharmacological intervention that may promote hair regrowth.
