Sporotrichosis is a chronic granulomatous mycosis caused by sporothrix complex. The course of sporotrichosis is always prolonged and even life-threatening, the treatment of this disease in an important scientific problem to be solved. The investigators previously found the predominance of subtype M2 macrophage which play an anti-inflammatory role in the lesions of sporotrichosis, the predominance of M2 macrophage may be responsible for the persistence of sporotrichosis; the investigators also found that local hyperthermia is effective in the treatment of sporotrichosis and hyperthermia treatment can activate the CRAC calcium channel in macrophages which triggers pro-inflammatory type M1 polarization and subsequent killing of sporothrix, however, the mechanism still calls for further investigation. The investigators hypothesize that hyperthermia leads to the activation of CRAC channels resulting in profound Ca2+ influx and Ca2+ upregulates NLRP3 inflammasome expression through inducing Nrf2 activation, then NLRP3 overexpression triggers M1 polarization and subsequent killing of sporothrix. Furthermore, the activation of Nrf2 upregulates STIM1 expression which forms a positive feedback for M1 type polarization of macrophages and further subsequent killing of sporothrix. The purpose of this project is to identify the hypothesis that hyperthermia could treat sporotrichosis by promoting pro-inflammatory type M1 polarization in macrophages, the mechanism by which hyperthermia could treat sporotrichosis is local hyperthermia could led to STIM1/CRAC calcium channel activation mediated calcium ions/Nrf2/NLRP3 induced M1 macrophages polarization and subsequent killing of sporothrix. The hypothesis will be identified at the cellular level, at the animal model level and at the clinical specimens level. The investigators believe that the project will guide the application of hyperthermia in the treatment of sporotrichosis and provide a new basis of theory and practice after the investigators achieving these goals.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
