It reacted with magnesium to form a 1∶1 fluorescent complex with λ ex / λ em =356/495 nm immediately at room temperature in ammonia ammonium chloride buffer (pH 10.7). A linear relationship was obtained in the magnesium concentration range of 0 160 ng·mL -1 with the detection limit of 0.04 ng·mL -1 . The proposed method was simple, rapid and sensitive. It has been successfully applied to the determination of trace magnesium in blood serum with recoveries of 103.75% and 98.16%, respectively.展开更多

By collecting relevant literature reports, echocardiography and several blood-related detection indicators such as SAA, IL-6, PCT and CRP were screened out. It has good clinical application value in the clinical diagnosis and treatment of Kawasaki disease in children, but there is no report on the application of echocardiography combined with blood SAA, IL-6, PCT and CRP detection in the diagnosis and treatment of Kawasaki disease in children. The author intends to explore the role of echocardiography combined with blood SAA, IL-6, PCT and CRP detection in the diagnosis and treatment of Kawasaki disease in children, hoping to achieve better results.展开更多
