Abstract
Objective: To analyze the expression of platelet membrane glycoprotein sialylation in primary immune thrombocytopenia and provide a reference for clinical diagnosis and treatment of the disease.
Methods: 100 children with primary immune thrombocytopenia diagnosed and treated in the Children's Hospital of Yunhe District Central Hospital of Cangzhou City, Hebei Province from January 2020 to June 2022 were included in the study group. All children were treated with dexamethasone (DXMS) shock therapy; Another 20 healthy children who underwent routine physical examination at the same time were selected and included in the control group. The study measured the platelet membrane surface in plasma using flow cytometry in two groups: the comparative study group and the control group. The study measured the positive rates of α 2,3-sialic acid (α 2, 3-sa) and α 2,6-sialic acid (α 2, 6-sa) in both groups. The study also measured the positive rates of α 2,3-sialic acid (α 2, 3-sa) and α 2,6-sialic acid (α 2, 6-sa) before and after treatment in the comparative study group. At the same time, an enzyme-linked immunosorbent assay was used to determine the content of sialic acid and sialidase activity and content in the serum. The detection values of α2, 3-SA, and α2, 6-SA expression of children in the study group and the control group were compared, and the detection values of α2, 3-SA, and α2, 6-SA expression of children in the study group before and after treatment were compared.
Results: There was no significant difference in the positive rate of α 2, 3-sa between the study group and the control group (t=0.852, P > .05); Study Group: The positive rate of α 2,6-sa was significantly lower than that of the control group (P < .05). In the study group, there was no significant difference in the positive rate of α 2,3-sa before and after treatment (P > .05). However, after treatment, the positive rate of α 2,6-sa was significantly higher than before (P < .05). The study found that the children in the study group had significantly higher levels of serum sialic acid content, sialidase activity, and content than those in the control group (P < .05). After treatment, the children in the study group showed a decrease in serum sialic acid content, sialidase activity, and content, which was statistically significant (P < .05) compared to before treatment.
Conclusion: The sialylation of platelet membrane glycoprotein is abnormally expressed in primary immune thrombocytopenia. The sialylation of platelet membrane glycoprotein may be involved in the occurrence and development of the disease. It is of great practical significance to diagnose and evaluate the therapeutic effect of the disease by detecting the sialylation of platelet membrane glycoprotein.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
