Ethnopharmacological Relevance: Pseudostellaria heterophylla (Tài Zǐ Shēn, TZS) is a traditional Chinese medicine with spleen and qi benefits. Its immunomodulatory, anti-fatigue, anti-stress, and lipid metabolism regulation effects have been clinically confirmed, but its role in meibomian gland dysfunction (MGD) is still unclear.
Aim Of The Study: This study aims to investigate the effect and mechanism of action of TZS in treating MGD.

Autoimmune uveitis (AU) is a sight-threatening ocular autoimmune disorder that often manifests as retinal vasculitis. Increased neutrophil infiltration around retinal vessels has been reported during the progression of AU, while how they function is not fully recognized. Neutrophil extracellular traps (NETs), produced by activated neutrophils, have been suggested to be detrimental in autoimmune diseases.

Leishmania (Viannia) braziliensis causes cutaneous and mucocutaneous leishmaniasis. Macrophages are host cells for parasite replication and act as effector cells against the parasite. The two main macrophage phenotypes (M1 and M2) and their polarisation states have been implicated in Leishmania infection despite scarce data on L.

No effective vaccines or treatments are currently available for severe fever with thrombocytopenia syndrome (SFTS), a fatal tick-borne infectious disease caused by the SFTS virus (SFTSV). This study evaluated the potential of In-labeled anti-SFTSV antibodies targeting SFTSV structural proteins as single-photon emission computed tomography (SPECT) imaging agents for the selective visualization of SFTSV-infected sites. This study used nuclear medicine imaging to elucidate the pathology of SFTS and assess its therapeutic efficacy.
