Chinese Journal of Ocular Fundus Diseases 2010;26(5):414-417
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.

Many methods can by used for the quantitative determination of the three types of immu-noglobulin. On the basis of the single radial immuno-diffusion method used by John L. Fahey,certain modifications have been made on the methods of diluting standard solutions and theirconcentrations, and the standard concentration of the immunoglobulins and the antibody-con-taining agar diffusion plates. In order to find the optimum condition of cultivation, theeffects of various temperatures and various cultivation time given by G. Mancini et al havebeen checked, and satisfactory standard curves have been obtained. Therefore, the accuracyof the analytical results is guaranteed. According to the results obtained, there is no observable effect on the diameter of theprecipitating ring when the temperature in culture-box is 35?C to 40?C and the cultivationtime extends to 96 hrs.

Objective To observe the effect of comfort levels in patients during long-term video electroencephalographic(VEEG) monitoring on the monitoring effect. Methods A total of 168 patients with consecutive epilepsy were observed about the Bruggrmann comfort scale(BCS) and artifacts of VEEG during VEEG monitoring. Pearson′s correlation coefficient was used to evaluate a possible correlation between BCS and artifacts. Results The average single score before VEEG, including psychological comfort, social comfort, comfortable environment and overall comfort was (2.87±1.04), (2.63±0.98), (2.40± 1.25), (2.84 ± 0.90), (2.69 ± 1.07) points, which was (2.06 ± 1.38), (1.66 ± 1.40), (1.89 ± 0.57), (1.83 ± 1.24), (1.86 ± 1.19) points after VEEG. There was significant difference between 2 groups (t=4.011-6.353, P<0.05). The overall comfort score and the average single project blinks or eye movement artifacts, physical artifacts, chewing or swallowing artifacts and electrocardiogram artifacts were negatively correlated (r=-0.843--0.585, all P < 0.05), which would reduce the number of these artifacts when increased; there was no correlation (r=-0.204,-0.158, P>0.05) between the average single score of comfort and sweating, skin artifacts, and electrocardiogram artifact. Conclusions There is a significant negative correlation between patient's BCS and the occurrence of artifacts during VEEG monitoring. Comfort evaluation and comfort care before monitoring has great significance in raising the long-term VEEG monitoring accuracy.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.
