Objective To analyze the onset, clinical manifestation, causation, complications of pediatric uveitis. MethodsOne hundred and two patients with uveitis under 16 year-old were retrospectively studied. They visited the clinic in Peking University First Hospital from November 1979 to December 2008. Their age ranged from 2.5 to 16 years old, with a mcan of 11.9 years. Routine exam was carried out, including visual acuity, slit lamp, fundus, and laboratory workup. The diagnosis and classification were made by the anatomic location according to the standard of The International Uveitis Working Group. The data of disease history, age of onset, manifestation, recurrence, causation, systemic diseases, complications, and lab examination were analyzed. Results A total of 102 patients (170 eyes)with pediatric uveitis were included in this study, 68 patients (66.6%) were bilateral cases. Anterior uveitis represented in 38 patients (37.3% ), intermediate uveitis in 19 (18.6%), posterior uveitis in 10 (9.8%),and panuveitis in 35 (34.3%). The disease duration was from five days to 2.4 years, with a mean of 3.6 months. The follow-up time was two weeks to more than ten years. The first three causes of pediatric uveitis were juvenile idiopathic arthritis, Vogt-Koyanagi Harada disease, and Behcet's disease. 36 patients were found with complications, and among them 19 had complicated cataract, seven had secondary glaucoma, five had corneal band dystrophy, 12 had iris synechia (both anterior and posterior), one had retinal detachment, two had eye atrophy, and one patient with juvenile idiopathic arthritis had bilateral femoral head necrosis because of the use of steroid and hip joint was replaced. There were ten children suffering more than two complications. Conclusions Pediatric uveitis is a possible blindness disease with variety of etiology and manifestations, and tends to cause complications. Early and special attention must be taken to avoid serious consequences.

Objective:To investigate the function of the quality factor in the growth of the total heath expenditure, in order to provide references for making the object of the health policy. Methods: Through the decomposition the identical equation of the growth of the total expenditure on health, to analyze the contribution of medical service quality and its factor. Results: The sustaining improvement of medical service quality in the important factor on the constant growth of the total expenditure on health. Conclusion: The primary objective of health policy is to improve the quality of medical services, and the secondary is to control the expense.

Isocitrate dehydrogenase 1 (IDH1), a key rate-limiting enzyme in tricarboxylic acid cycle,is found within the cytoplasm and peroxisomes.In recent years, IDH1 mutation is discovered in most gliomaand its large scale metabolites, 2-hydroxyglutarate, may be involved in tumor as potential carcinogens, and isshown to be closely related to better patients' survival as well.IDH1 mutation is anticipated to be a novel genet-ic biomarker which will guide the treatments of clinical glioma.

As an important incentive for cardiovascular disease, cancer, diabetes and other chronic diseases, obesity after cardiovascular disease and cancer has been listed as the third largest threat to human health by World Health Organization. Recent research has shown that obesity is associated with colorectal cancer, esophageal cancer, kidney cancer, endometrial cancer, however, it has not been fully disclosed that the mechanism could lead to an increased risk of tumors. Leptin and adiponectin are a kind of hormone secreted by adipose tissue, which involve in the energy metabolism, and play an increasing significant role in the tumors' affecting factors.

Objective To establish a method to determine dicofol and eight pyrethroid pesticides residues in vegetables and fruits by gas chromatography.Methods The crushed samples were extracted with organic solvent,then the extract was analyzed by DM-17 capillary column gas chromatography after being purified by PestiCarb-NH2 cartridge and silica cartridge solid phase extraction.Results The detection curve covered the linear range of 0.10-2.0 ?g/ml .The minimum detection limit was 0.011-0.090 ?g/kg.The rates of recovery were 85.4%-105%.The variable coefficient(RSD) was under 7.0%.Conclusion This method has the advantages of less disturb, simple and high accuracy, and it can be applicable to the routine analysis of dicofol and pyrethroid pesticides residues.

Objective To compare the short-term follow-up cu ra tive effect of primary total hip replacement (THR) in treating fresh and old fem oral neck fractures. Methods Double follow-ups with an in terval of 13 months were performed in patients with femoral neck fractures under going THR in our department from January 1997 to October 1999. Results After a follow-up for 37-62 months (mean 44 months), we obtained f ull data of 47 patients [41-77 years old, (61.8?5.22) years old] with preoperative Harris score of 28.40?10.14 and postoperative score of 85.20?7. 91. The Harris score of patients with fresh femoral neck fractures (FFNF) incr eased from 21.60?8.73 preoperatively to 82.50?9.81 postoperatively〔at age of (63.50?5.53) years〕 and that of patients with old femoral neck fracture (O FNF) from 37.70?13.50 to 90.63?5.79, [at age of (58.90?7.81) years]. Of 47 patients, only one case had dislocation once within six weeks postoperative ly during function exercise and recovered after manual reduction. Another one wi th excellent function evaluation was given again internal fixation three years a fter THR because of femoral shaft fracture and obtained satisfactory recovery. N o complications were found in other patients. The mean Harris score in patients with OFNF was significantly higher than those with FFNF ( P

Objective: To study the general characteristics of autistic children. Methods: The data of 1176 autistic children who were diagnosed in the Institute of Mental Health, Beijing Medical University was gathered, descriptive statistics were done with SPSS software. Results: As many as 35.10% of the autistic children are identified by their parents having problems in behavior until they were 3 years old. The average age of consulting was 60.61?26.8 months. Only 21.43% children were brought to child psychiatrists under the age of 3. They were brought to hospital 35.03?27.86 months after being discovered the symptoms.Conclusion:Health education for child autism should be strengthened so that it can be early identified.

Object To study the effect of rare-earth elements La3+ on growth of hairy roots and normal roots of Rheum palmatum L and their yield of anthraquinones. Methods The biomass and an- thraquinone yield of two hairy clones DH5c, DH7a, and normal root NOR cultures of R. palmatum were evaluated statistically after various concentration of La3+ were administrated into culture medium. Results Significant differences of biomass yield and anthraquinone yield were shown among six La3+ concentrations, in which 10 mg/L showed obvious inhibitory effect for root growth and 1. 0 mg/L was the best for anthraquinone yield. In general, aloe-emodin and rhein were predominant in five anthraquinones after treated with the rare-earth element. Conclusion The growth of hairy root cultures of R. palmatum and their anthraquinone yield are greatly promoted by addition of La3+ to the medium.
