Chinese Journal of Postgraduates of Medicine 2017;40(2):190-192
Hypocalcemia often exists in critical illness children. Most of the sick children do not have an underlying disease of calcium homeostasis, and the mechanism of the hypocalcemia is complicated. Abnormal values of blood calcium may be a sign of critical illness and normalize spontaneously with resolution of the primary disease process. Hypocalcemia may be a autoprotection , and it may be harmful if we try to correct it. This article focuses on the theory and clinical treatment of hypocalcemia in critical illness children.

4.Research progress of infectious mononucleosis
Chinese Journal of Postgraduates of Medicine 2016;39(5):475-478
Infectious mononucleosis(IM) was one of the clinical common diseases, caused by epstein-barr virus infection in more than 90%patients. Changes of the surface antigen of the B cells with EB virus infection caused strong immune response of T lymphocytes, besides, helper T lymphocyte, dendritic cells, NK cells also played an important role in the pathogenesis of IM. The incidence of IM was not only closely related with social environment in childhood, but also closely with the number of siblings, birth order, and sunshine factor. In addition to the typical clinical manifestations, IM also can cause a variety of complications, such as spleen rupture and necrotizing mediastinitis , and could be life-threatening. Auxiliary examination means such as state of peripheral blood lymphocyte apoptosis, plasma proteomics, cerebrospinal fluid analysis, load test of EB virus can help to diagnose. Application of antiviral drugs was wider, but hormone was still controversial. Vaccine research progress had been slow, but there were vaccines for human test, which will provide effective measures for the prevention of IM.

Proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitor is recently added to the list of effective lipid-lowering drugs in addition to statins, which can reduce low density lipoprotein cholesterol, treat increased low density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (ASCVD) patients. In the past 30 years, the prevalence of dyslipidemia increased significantly. LDL-C characterized dyslipidemia is an important risk factor of ASCVD and a part of metabolic syndrome, which exists before or after or at the same time of the appearance of obesity, diabetes, and glucose intolerance, coronary heart disease and other diseases. Decreasing LDL-C level can significantly reduce the incidence and mortality risk of ASCVD. In this paper, the research on the regulation of dyslipidemia by PCSK9 inhibitors is discussed.

Objectives To explore the changes of serum interleukin-33 (IL-33), IgA anti-endothelial cell antibodies (AECA) and IgA anticardiolipin antibodies (ACA) in acute stage of Henoch-Sch?nlein purpura (HSP) in children and its clinical signiif-cance. Methods Thirty-seven children with acute HSP admitted to hospital were selected from Nov.2012 to Jan.2013. Twenty healthy children were selected as healthy controls. The serum levels of IL-33 were measured by double anti-body sandwich en-zyme-linked immunosorbent assay (ELISA) and the serum levels of AECA-IgA and ACA-IgA were detected by double antigen sandwich ELISA. Results Serum levels of IL-33, AECA-IgA and ACA-IgA in patients with acute HSP were signiifcantly higher than those in healthy controls (P<0.001). According to different clinical types, the serum levels of IL-33, AECA-IgA and ACA-IgA were signiifcantly higher in mixed-type HSP (with joint involvement and gastrointestinal symptoms and/or kidney damage) than those in HSP patients with only joint, abdomen or renal involvement (P<0.05). Serum levels of IL-33 in acute stage of HSP had a positive correlation with AECA-IgA (r=0.752, P<0.001) and ACA-IgA (r=0.788, P<0.001). Conclusions The immune pathological injury in vessels caused by the interaction of IL-33, AECA-IgA and ACA-IgA may be the important pathogenesis of HSP, which may provide a clue for the early diagnosis and treatment for HSP.
