RESUMO
BACKGROUND: Acquired aplastic anemia (AA) is a life-threatening disease associated with an imbalance in Th17/Treg cells. Regulating this balance may be an effective treatment approach for AA. Rhodiola rosea has shown efficacy in AA treatment, but its mechanisms remain unclear. PURPOSE: We investigated salidroside's effect (a component of Rhodiola rosea) on Th17/Treg balance in adult AA patients and a mouse model. METHODS: HIF-1α mRNA and protein levels were measured in AA patients' peripheral blood. Flow cytometry, qRT-PCR, and WB analyzed salidroside's impact on T cell differentiation, Th17 cells, Treg cells, STAT3, HIF-1α, and RORγt expression. ELISA measured hematopoietic growth factors in mouse serum. RESULTS: AA patients exhibited elevated HIF-1α levels. Salidroside improved hematopoietic function, increasing blood cell count and enhancing bone marrow. Salidroside induced SCF, TPO, and IL-3 expression while inhibiting IL-2 in mice. Salidroside reduced STAT3, HIF-1α, RORγt, and IL-17a, while increasing FoxP3 expression, correcting the Th17/Treg imbalance in vitro and in vivo. CONCLUSION: Salidroside has potential as a novel AA treatment by correcting the Th17/Treg imbalance through the STAT3/HIF-1α/RORγt pathway.

Lymphangioma is a rare benign lymphatic system proliferation, especially in the vulva. The general treatment principle is determined by clinical manifestations, lesion size, anatomic location, and complications. Treatment options include surgical excision, carbon dioxide laser, cryotherapy, electrocoagulation, and sclerosing agent injection. In the absence of evidence to guide the choice of significant treatment modalities, treatment options are often based on the experience of the treatment team and the patient's preferences. This study presents a case of primary vulva lymphangioma circumscriptum treated with fire needle therapy, photodynamic therapy, and cryotherapy. Furthermore, the combination of fire needle and photodynamic therapy demonstrated exceptional comprehensive effects in pain, wound healing and cosmetic.
