https://www.selleckchem.com/products/osmi-1.html Subcutaneous fat necrosis (SCFN) is an inflammatory disorder of the adipose tissue that commonly presents in neonates as tender subcutaneous nodules on the trunk and extremities with hypercalcemia as a potential complication. We report the case of a 3-month-old female who presented with circular alopecia of the scalp and was found to have histopathologically confirmed SCFN. Recognition of SCFN as a cause for alopecia in young infants may allow prompt screening for hypercalcemia and reduce the risk for associated morbidity and mortality.Since Traditional Chinese Medicine is a complex mixture of multiple components, the application of methodologies for evaluating single-components Western medicine in TCM studies may have certain limitations. Appropriate strategies that recognize the integrality of TCM and connect to TCM theories remain to be developed. Yang-Xin-Ding-Ji Capsule is originally from a classical traditional Chinese medicine formula used for the treatment of arrhythmia. In this study, we used UPLC-Q-TOF/MS detection coupled with metabolic research and network pharmacology analysis to study the scientific connotation of YXDJ. A total of 33 absorbed constituents and 23 metabolites were identified or tentatively characterized in dosed plasma and urine, and the possible metabolic pathways were mainly methylation, oxidation, sulfation, glucuronidation and deglucosylation. What's more, we optimized the conventional process ways of network pharmacology by collecting targets based on absorbed constituents into blood. The Constituents-Target-Disease (CTD) and KEGG pathway analysis revealed that 24 absorbed constituents, 32 target genes and 10 key pathways such were probably related with the efficacy of YXDJ against arrhythmia. The results provided a scientific basis for understanding the bioactive compounds and the pharmacological mechanism of YXDJ.Signal inhibitory receptor on leukocytes-1 (SIRL-1) is an inhibitory r
