Objective To investigate the pathogens of acute respiratory infection of children.Methods A total of 159 children with acute respiratory infection who were hospitalized in our department from August 2005 to January 2006 were involved in this study.The serum IgM antibody of 18 pathogens were detected by indirect immunofluorescence test.The 18 pathogens included respiratory syncytial virus(RSV),adenovirus(ADV),influenza A(H1N1,H3N2)and B viruses,parainfluenza viruses(PIV) type 1,2,3 and 4,coxsackie virus B1(CBV1),coxsackie virus A7(CAV7),echovirus(ECHO7),haemophilus influenzae(HI),klebsiella pneumoniae(KP),bordetella pertussis(BP),bordetella parapertussis(BPP) and legionella pneumophila serotype 1 and 12.Results The evidence of specific IgM was obtained in 103 of 159 patients(64.78%).Influenza A was found in 66 cases(64.08%),influenza B in 49 cases(47.57%),enterovirus in 26 cases(25.24%),RSV in 18 cases(17.48%),PIV in 11 cases(10.68%),and co-infection in 66 cases(64.08%),1/ 3 of them were co-infected with influenza A and B.Conclusions Viruses are the most common agents of acute respiratory infection.Influenza virus is predominant among them.

Chinese Journal of Contemporary Pediatrics 2011;13(1):32-35
OBJECTIVETo study the influence of near-work and outdoor activities on myopia progression in school children.
METHODSEighty 7-11-year-old school children with myopia were randomly assigned into an intervention group (n=41) and a control group (n=39). The children in the intervention group did near- and middle-vision activities less than 30 hrs per week and more outdoor activities than 14-15 hrs per week. Myopia progression was observed regularly over 2 years after which ophthalmologists administered questionnaires regarding near-vision work (reading, writing and using computer), middle-vision work (watching TV and extracurricular learning activities), outdoor activities, using nature light, wearing glasses, etc.
RESULTSThe annual mean myopia progression (0.38 ± 0.15 D) in the intervention group was significantly lower than that in the control group (0.52 ± 0.19 D; P<0.01). The children in the two groups spent similar amounts of time in near-vision activities, but the children in the intervention group spent less time in middle-vision activities (P<0.01) and more outdoor activities (13.7 ± 2.4 vs 6.2 ± 1.6 hrs/wk; P<0.01). When considering all children in the study, there were 4 factors that significantly correlated with less myopia progression: more outdoor activities, more time spent wearing glasses, more time spent in natural light and less time using a computer. When analyzing the intervention group separately, more outdoor activity was inversely correlated with myopia progression (t=-2.510, P<0.05). Separate analysis of the control group indicated that more time wearing glasses was correlated with less myopia progression (t=-3.115, P<0.05).
CONCLUSIONSMyopia progression in school children may be slowed by more outdoor activities, more time spent in natural light and more time wearing corrective glasses.

Alteration in the structural appearance of the optic disk and retinal nerve fiber layer usually precedes the development of reproducible glaucomatous visual field defects.Identification of these changes is important in the diagnosis and treatment of glaucoma at an early to moderate stage and in monitoring its clinical course.This paper reviews the optical coherence tomography(OCT),Heidelberg retina tomography(HRT),optic nerve head stereophotograph(ONHP)and scanning laser polarimetry(SLP) in the field of open angle glaucoma.

Abstract?AlM: To evaluate the visual impairment in cerebral palsy children with series objective indicators, and conclude their clinical features of visual function.? METHODS: Objective tests including following pursuing test, optokinetic nystagmus(OKN) drum test, refractive error examination, fundus examination, ocular deviation examination, pattern visual evoked potential ( P-VEP ) tests and brain magnetic resonance imaging ( MRl) were carried out in 43 cerebral palsy children ( 86 eyes ) with ocular visual dysfunction; The visual impairment data of the cerebral palsy children were collected, and the clinical features and possible mechanism were analyzed.?RESULTS: 1. Of the 43 cerebral palsy children ( 86 eyes) with the visual impairment presented diversified, 25 ( 50 eyes, 58. 1%) of refractive error, 24 ( 48 eyes, 55. 8%) of strabismus, 12 ( 24 eyes, 27. 9%) with nystagmus, 19 ( 38 eyes, 44. 2 %) of optical nerve atrophy or hyperplasia, 35 ( 70 eyes, 81. 4%) of VEP abnormality. Among children with spastic cerebral palsy, the incidence of visual impairment was statistically significant difference compared with other groups (P<0. 01). 2. There were 16 cases (32 eyes,37. 2%) with esotropia, 6 cases ( 12 eyes, 14. 0%) with exotropia and 2 cases ( 4 eyes, 4. 7%) with vertical deviation. Strabismus was most common in spastic cerebral palsy children, totally 13 (26 eyes, 30. 2%) with esotropia, and exotropia was common in hypotonia and other types cerebral palsy children; 3. 23 ( 46 eyes, 53. 5%) with hyperopia, 8 ( 16 eyes, 18. 6%) with myopia, 16 ( 32 eyes, 37. 2%) with astigmutism and 14 cases (28 eyes, 32. 6%) with anisometropia;4. Cerebral palsy children were usually with decreased VEP amplitude and prolong latency, and poor wave formation, mostly in spastic cerebral palsy children; 5. Visual abnormality was most common in occipital cortex damage and periventricular leukomalacia ( PVL ) . The incidence in PVL and occipital cortex had no statistically significant difference ( P > 0. 05 ), no nystagmus in patients with severe occipital cortex damage.?CONCLUSlON: Cerebral palsy children were usually with visual impairment, and presented with special clinical features; Comprehensive objective visual tests are accurate and reliable for evaluation of the visual function in cerebral palsy children.

Objective To develop a multiplex PCR-based reverse line blot(mPCR/RLB) hybridization assay to detect,simultaneously,seven genes encoding AR-erm(A/TR),erm(B),mef(A/ E),tet(M),tet(O),aphA-3,aad-6 and two AR-related genes,int-Tn and mreA in group B streptococcus.Methods Nine pairs of specific primers and Oligonucleotide probes targeting erm(A/TR), erm(B),mef(A/E),tet(M),tet(O),aphA-3,aad-6 int-Tn and mreA respectively were modified according to former studies or designed in this study.The primers and probes were labeled with biotin and amino,respectively.The nine genes were amplified simultaneously in the same tube.PCR product hybridized with the probes labeled in the BiodyneC nylon membrane to detect the nine genes.To detect the sensitivity and specificity of the method developed,PCR with single pair of primer targeting each gene were tested in 318 isolates tested and the results were compared with the one abtained by RLB.Results The nine resistance-related genes could be successfully detected by mPCR/RLB assay developed in this study.Based on sequencing,21 of 22 isolates with mef had mef(E)and eight of 353 with int-Tn had an atypical sequence.Except for the above 29 genes,all the others corresponded well with the results obtained by single pair primer PCR.Conclusion The mPCR/RLB assay developed in this study is simple,rapid and suitable for surveillance of antibiotic resistance in GBS.

Cooperation hydrogen production was carried out using Rhodopseudomonas sp. DT and Enterobacter aerogenes. The effects of the initial ratio of Rhodopseudomonas sp. DT and E. aerogenes, culture temperature, and carbon source on the cooperation hydrogen production were investigated. The results suggested that cooperation hydrogen production rate was highly affected by the initial ratio of Rhodopseudomonas sp. DT and E. aerogenes. The mixed bacteria of Rhodopseudomonas sp. DT and E. aerogenes with 1:1 initial ratio benefited to the cooperation hydrogen production, which led the hydrogen production rate and duration of gas production to 3.1 mol H2/mol glucose and 81 h, respectively. The pH dynamics analysis of culture medium further discovered that the pH of the mixed bacteria with 1:1 initial ratio changed from 6 to 7 smaller than other conditions, which was probably fitted to produce hydrogen. Furthermore, the mixed bacteria with 1:1 initial ratio had the higher hydrogen production efficiency at temperatures of 28?C and 37?C than at 20?C, and without any hydrogen production at temperature of 50?C. The carbon sources of glucose, succinate acid, malic acid could be used to produce hydrogen by the mixed bacteria. Even the soluble starch, unused by Rhodopseudomonas sp. DT, was also decomposed by the mixed bacteria to produce hydrogen with the conversion efficiency of 8.22%. The glucose was the optimal carbon resource, and the conversion efficiency could reach to 36.11%. The results, further, implied that the cooperation hydrogen production could enlarge the use of the carbon sources.
