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.
3.Clinical characteristics and genetic researches of CHD2 myoclonus encephalopathy
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.
4.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.
5.An Experimental Study on the Biocompability of Porcelain Compounded With Nanostructured Material
Journal of China Medical University 2001;30(2):105-107
Objective: Our aim was to evaluate the biocompability of porcelain compounded with nanostructured material. Methods:The proliferation of the NIH3T3 cells were investigated using a tetrazolium-based colorimetric assay(MTT assay).Maceration extract of four tested materials were added into culture plate .The samples were tested with ultraviolet spectrophotometer in 490 wavelength at 1,3,5,7 days after the addition of extract. Morphology of these cells was also observed with phase-contrast microscope. Results: There was no obvious difference among three kinds of prosthetic materials in the optical absorbance and the cells growing in the extract showed normal morphology. Conclusion: The toxicity graduation of the porcelain compounded with nanostructured material is 0. This material has a good biocompability and can be used clinically.

Clinical Medicine of China 1999;0(02):-
Objective To compare the effects of bifidobiogen with enzyme inductor(luminal, nikethamidum) in treatment early neonatal hyperbilirubinemia. Methods 92 babies with early neonatal hyperbilirubinemia were divided into 2 groups, randomly. 49 patients were treated with bifidobiogen 350 mg/(kg. d) and phototherapy. Other 43 patients were treated with enzyme lnductor luminal 5mg/(kg. d) ; nikethamidum 100mg/(kg. d)and phototherapy as the control group. Results The total effective rate in the treatment gr0up(77. 6% ) was higher than that in the control group (44. 2% ), P
