Recent advances in systemic lupus erythematosus and microbiota: from bench to bedside

Frontiers of Medicine 2022, Volume 16, Issue 5,   Pages 686-700 doi: 10.1007/s11684-022-0957-7

Abstract: Systemic lupus erythematosus (SLE) is a complicated autoimmune disease affecting multiple systems and organs. It is highly heterogeneous, and it preferentially affects women at childbearing age, causing worldwide social burden. The pathogenesis of SLE mostly involves genetic predisposition, epigenetic dysregulation, overactivation of the immune system, and environment factors. Human microbiome, which is mostly composed of microbiota colonized in the gut, skin, and oral cavity, provides a natural microbiome barrier against environmental risks. The past decade of research has demonstrated a strong association between microbiota and metabolic diseases or gastrointestinal diseases. However, the role of microbiota in autoimmunity remains largely unknown until recently, when the technological and methodological progress facilitates further microbiota research in SLE. In this review, the latest research about the role and mechanisms of microbiota in SLE and the advances in the development of diagnostic and therapeutic strategies based on microbiota for SLE were summarized.

A novel intravenous general anesthetic--- emulsified isoflurane: from bench to bedside

Cheng Zhou, Jin Liu

Frontiers of Medicine 2012, Volume 6, Issue 4,   Pages 381-387 doi: 10.1007/s11684-012-0229-z

Abstract:

Application of volatile anesthetics greatly alters modern medicine. There are obvious advantages of volatile anesthetics such as strong anesthetic potency, rapid onset and elimination through respiration system. Isoflurane is one of the most widely used volatile anesthetics in clinic. Emulsified isoflurane, the emulsion of isoflurane, is a novel intravenous general anesthetic. With the development of emulsified isoflurane in the past fifteen years, its utility has spread from intravenous general anesthesia to various fields including regional anesthesia, organ protection, as well as anesthetic pharmacological study. In this review, we will summarize literatures of emulsified isoflurane about its history, clinical application and future potential utility in the above mentioned fields.
