1.Oxidative stress and autism
International Journal of Pediatrics 2012;39(1):99-101
Autism in children is a complex disease of developmental disorder in nervous system,characterized by social deficits,impaired language and communication,stereotyped and repetitive behaviors.Studies indicate oxidative stress is associated with autism.Because of genic and environmental factors,children with autism are susceptible to oxidative stress.Oxidative stress induce the development of autism through abnormal metabolism of the membrane lipid,inflammation and excitotoxicity,autoimmunity,energy metabolism disorder,et al.Anti-oxidation might be a safe and effective therapy for autism.
2.Comparison of two methods for content analysis of vaccine particles in freeze-dried human rabies vaccine (Vero cells) bulk and final bulk
Chinese Journal of Biologicals 2024;37(07):866-872
Objective To compare and analyze two methods for determination of vaccine particle content in freeze-dried human rabies vaccine(Vero cells)bulk and final bulk,and to provide experimental basis for establishing standard detection method for particle content and purity of rabies vaccine products.Methods The samples were subjected to vaccine particle cracking,BCA quantification,and size exclusion chromatograghy-high performance liquid chromatography(SEC-HPLC)analysis. BCA-SEC relative area method and BCA-SEC vaccine particle standard curve method were used to detect the total protein concentration of the bulk and final bulk,separately,and the content of vaccine particles was quantitatively analy-zed. Finally,the detection results of the two methods were compared and analyzed.Results The content of vaccine particles in freeze-dried human rabies vaccine bulk was determined to be within 256-305 μg/mL by the two methods,with an average value of 267-285 μg/mL,and the relative standard deviations(RSDs)ranged from 5. 8% to 10. 2%,with good consistency between two methods. The content of vaccine particles in freeze-dried human rabies vaccine final bulk was determined to be in the range of 149-169 μg/mL by the two methods,with an average value of 152-164 μg/mL,and the two methods showed the RSDs between 0. 9%-4. 7% with good consistency.Conclusion The measured value by BCA-SEC standard curve method deviates less from the expected value and is closer to the actual situation of samples,so it is recommended to use this method as a reference for enterprises.

6.Advances in pathogenesis, diagnosis and treatment of paroxysmal nocturnal hemoglobinuria
Journal of Leukemia & Lymphoma 2016;25(4):252-256
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder of hematopoietic stem cells due to acquisition of somatic mutations.Somatic mutations in phosphatidylinositol glycan class A (PIGA) account for intravascular hemolysis and other PNH manifestations,but the pathophysiology of clonal expansion of PNH cells cannot be elucidated clearly.PNH is closely related to aplastic anemia and myelodysplastic syndromes.Today,the gold standard for PNH is flow cytometry to detect the absence or severe deficiency of glycosylphosphatidylinositol (GPI)-anchored proteins on white and red blood cells.However,PNH diagnosed by phenotype is a group of heterogeneous disease in pathogenesis.Eculizumab,a first-in-class monoclonal antibody that inhibits terminal complement,is highly effective in stopping intravascular hemolysis and improving quality of life.Further research on the pathogenesis of PNH would be helpful to understand the underlying reasons for PNH phenotype cells in different patients,improve differential diagnosis and more targeted and specific therapy.Research progress in recent years will be reviewed in this article.

Chinese Journal of Applied Clinical Pediatrics 2016;31(24):1848-1850
In recent years,with the improvement of the genetic inspection techniques,some of the epileptic en-cephalopathy whose causes were unknown are associated with genetic factor.The result shows that one kind of epileptic encephalopathy may be associated with a variety of genetic mutations or copy number variation (CNV),one gene muta-tion or CNV also may lead to a lot of epileptic encephalopathy.In addition,the new clinical features and genetic poly-morphism were discovered increased.So that epileptic encephalopathy which named from the disease -causing gene was also increased.This article will summarize the clinical phenotype characteristics,genetic studies and future of the newly discovered CHD2 myoclonus encephalopathy.
8.Vitamin B6 related epilepsy
Chinese Journal of Applied Clinical Pediatrics 2016;31(24):1841-1848
Vitamin B6 related epilepsy is a group of epileptic diseases,seizures in which could not be con-trolled by antiepileptic drugs,but could be controlled or obviously improved by vitamin B6 .It comprises of pyridoxine dependent epilepsy and pyridoxine responsive epilepsy predominantly,and the latter includes vitamin B6 responsive in-fantile spasms,pyridox(am)ine -5′-phosphate oxidase (PNPO)deficiency,hyperphosphatasia mental retardation syndrome (Mabry syndrome)and so on.The clinical presentations of the diseases above are nonspecific,manifesting as refractory seizures onset in neonatal or infantile period,which need to be distinguished from other diseases such as new-born hypoxic ischemic encephalopathy,Ohtahara syndrome and non -ketotic hyperglycinemia.Pyridoxine dependent epilepsy,PNPO deficiency and Mabry syndrome have relative specific biomarkers and known disease -causing genes, which are helpful for diagnosis.It is suggested that pyridoxine or pyridoxal phosphate should be tried first for all patients started seizures early (including all infantile spasms patients),avoiding missing these diseases.And once diagnosed,vi-tamin B6 should be maintained long -term or all the life according to the detailed disease.
9.Research progress of Thrombospondin type-1 domain-containing7A in membranous nephropathy
Journal of Medical Postgraduates 2017;30(7):775-779
After the research of PLA2R1 and its antibodies, Thrombospondin type-1 domain-containing 7A and its antibodies to membranous nephropathy (MN) has made a new understanding.Some researches have reported that the antibodies of PLA2R1 and THSD7A were mutually exclusive in MN, because THSD7A was found in PLA2R1-negative MN patients.But the latest researcher showed that these antibodies can be both positive in MN patients.Similar to the function of PLA2R1, THSD7A can assist clinical diagnosis, treatment, and monitor of MN.In contrast to PLA2R1, THSD7A was also highly expressed on both human and murine podocytes.We can use the mice model to study the pathogenesis of THSD7A-associated MN in the future.In this review, we describe the structure and function of Thrombospondin type-1 domain-containing 7A and its autoantibodies, highlight its role in MN and suggest possible aspects of its future clinical application.
