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.

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.

Surgery, selective radioiodine therapy and thyroid stimulating hormone suppressive therapy are the standard treatment modalities for differentiated thyroid cancer (DTC). After therapy, most DTC patients could get good prognosis. However, some patients with distant metastasis lose the ability to concentrate radioiodine at early time or during the treatment, and develop radioiodine-refractory DTC (RAIR-DTC). These patients progress quickly and have high mortality. Looking for effective treatments for these patients has been the hot spot in research of thyroid carcinoma. In this paper, we summarized the recent advances in the diagnosis and treatment of RAIR-DTC, hoping to early identify these patients and buy time for early intervention of other possible beneficial treatments such as targeted therapy and radiotherapy.
