According to pathogenesis, MCD can be further divided into different subtypes based on the status of human herpes virus-8 （HHV-8） infection. Of the HHV-8 negative MCD （also named as idiopathic MCD [iMCD]）, there is a peculiar subtype named TAFRO syndrome which constitutes a constellation of unique clinical manifestations （T： Thrombocytopenia, A： Anasarca, F： myelofibrosis, R： Renal dysfunction, and O： Organomegaly）. This syndrome, first reported in Japan[2] has been reported mostly in the Japanese population and occasionally in Caucasians. There is no such case reported in China. We herein report the first patient with TAFRO syndrome in China with confirmed myelofibrosis.展开更多

The sensitive of virus to heat proposed temperature treatment as an effective method against coronavirus. Here, we proposed several non-drug therapies including far-infrared, thermal air, thermal oxygen, ozone, hydrogen therapy and plasma physical therapy for immediate clinical trial and implementation. Compared with the drug therapy, these methods are safe without side effects, the highest benefit-to-risk ratio, user-friendly, and low implementation costs. It is urgent and significant to start these non-drug therapeutic design and implementation as early as possible, to determine the safety and effectiveness of these therapeutic methods.展开更多
