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.

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.

The "opening-closing-pivoting" theory on the six meridians is one of the difficult points in the study of Shang Han Lun (Treatise on Cold Diseases). The authors give an explanation on the space and time differentiation of three-yin and three-yang as well as the "opening-closing-pivoting" theory based on the predecessor's experience, and then analyze the physiological and pathological characteristics of the six-meridian disorders.

Objective To investigate the clinical efficacy and safety of topical corticosteroids as adjunctive plan in the therapy of bacterial corneal ulcers (BCU).Methods 62 eligible patients with confirmed BCU were screened and divided into 2 groups randomly.Both groups were treated with topical tobramycin for 3 weeks,the observation group received topical tobramycin for at least 48 hours and then treated with 0.02％ fluorometholone for 3 weeks,and decrement setp by step.Best spectacle corrected visual acuity(BSCVA),fluctuation of intraocular pressure (IOP) before and after therapy,time to corneal reepithelialization and clarity,severe adverse event were observed.Results After 3 weeks,BSCVA of both groups increased compared to their baselines,however,no significant difference between the two groups.Patients whose IOP exceed 21mm Hg in the control group was statistically more than that in the observation group(x2 =7.272,P ＜ 0.05).Follow up for 3 months,increasing of BSCVA in the observationgroup was significantly higher than the control group(t =2.388,P ＜ 0.05) ;and lOP of both two groups almost recuperated to baselines.Although the time to corneal reepithelialization of the control group (11.3 ± 4.5) d was shorter than observation group [(14.7 ± 5.2) d] (t =2.707,P ＜ 0.05),the recovery of corneal clarity in observation group was superior to control group (x2 =8.207,P ＜ 0.05).In addition,no severe adverse events were observed during this period.Conclusion Although prolong the healing time of corneal epithelium,corticosteroids as an adjunctive plan in the therapy of BCU may reduce immune-mediated damage,decrease scarring,control IOP fluctuation and improve BSCVA,but with no safety concerns.

The scientific indexes and methods for checking utilization and intact rates of analytical instruments are established by cybernetic principles, fozzy mathemetical mdthods, theories of systematic engineering, and actual conditions of working units. it is proved that the realization of scientific management and control to manipulators, instruments and working enviroment can raise the utilization and intact rates of analytical instruments, guarantee the assay quality of drugs, increase the efficiency of supervision and promote the research work in drug analysis. Definite social and economic results are thus obtained.

Objective: To explore the effects of Layhey’s and Lawrence’s reconstruction procedures on nutritional status and digestive symptoms following total gastrectomy for gastric cancer.Methods: To analyze retrospectively 146 patients performed total gastrectomy for gastric cancer.Among them,83 cases were operated by Lahey’s reconstruction procedures and 63 cases by Lawrence’s.It was focused on the comparision of the body weight changing,nutritional status and digestive symptoms in 6 months after operation.Results: In 6 months after operation,the weight loss of Lawrence group was less than that of Lahey group significanly.For the level of total protein and albumin at that time,they increased in Lawrence group,but decreased in Lahey’ group,and the difference was significant.The changing tedency for hemoglobin level in Lawrence group was less than that of Lahey group,but there was no significant difference between them.For the quantity and frequency of food intake,there was no significnat difference between them.In Lawrence group,the number of patients with vomiting were less than that in Lahey’group significantly.Conclusion:The Lawrence reconstruction procedure is more reasonable following total gastrectomy for gastric cancer.

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.
