The inflammatory response of lung tissue and abnormal proliferation of pulmonary artery smooth muscle cells are involved in the pathogenesis of high-altitude pulmonary hypertension (HAPH). Halofuginone (HF), an active ingredient derivative of Chang Shan (Dichroa febrifuga Lour. [Hydrangeaceae]), has antiproliferative, antihypertrophic, antifibrotic, and other effects, but its protective effects on HAPH remains unclear.

, a high-altitude medicinal herb, possesses diverse therapeutic properties. This study conducted a comprehensive phytochemical analysis of the whole plant, leading to the isolation of 15 secondary metabolites (1-15) across various classes: flavonoids (), triterpenoids (, ), sesquiterpenoid lactones (, ) and furanocoumarins (, ) along with three steroids (). These compounds were characterized using NMR (HNMR,C NMR, 2D NMR), IR, HRMS and UV-VIS.

Background: High-altitude pulmonary edema (HAPE) is noncardiogenic pulmonary edema caused by exaggerated hypoxic pulmonary vasoconstriction and abnormally high pulmonary artery pressure. Some patients who develop HAPE have more chances to develop HAPE again on reinduction to high altitude (HA). This was a pilot project to look for a suitable drug (acetazolamide, nifedipine, or tadalafil) that could be used prophylactically in HAPE patients on reinduction to HA.

Background: The hypobaric hypoxic atmosphere can cause adverse reactions or sickness. The purpose of this study was to explore the preventive effect and mechanism of human umbilical cord mesenchymal stem cells (hUC-MSCs) on acute pathological injury in mice exposed to high-altitude.
Methods: We pretreated C57BL/6 mice with hUC-MSCs via the tail vein injection, and then the mice were subjected to hypobaric hypoxic conditions for five days.

Nitric oxide (NO) is an essential molecule in biomedicine, recognized for its antibacterial properties, neuronal modulation, and use in inhalation therapies. The effectiveness of NO-based treatments relies on precise control of NO concentrations tailored to specific therapeutic needs. Electrochemical generation of NO (E-NOgen) via nitrite (NO ) reduction offers a scalable and efficient route for controlled NO production, while also addressing environmental concerns by reducing NO pollution and maintaining nitrogen cycle balance.
