OBJECTIVETo study the diagnostic values of cerebrospinal concentrations of neopterin (NPT) and S100b for central nervous system infections in children.

METHODSEnzyme-linked immunosorbent assay was used to determinate the cerebrospinal concentrations of NPT and S100b in children with central nervous system infections and control children. The two groups of children were compared in terms of the two indicators, and the diagnostic values of the two indicators were evaluated by ROC curve analysis.

RESULTSChildren with viral encephalitis had significantly increased cerebrospinal concentrations of NPT and S100b compared with the control group and children with purulent meningitis (P<0.01); there was no difference in the cerebrospinal concentration of NPT between children with purulent meningitis and the control group, while the concentration of S100b in the purulent meningitis group was significantly higher than in the control group (P<0.01). According to the ROC curves, S100b was more valuable than NPT in the diagnosis of viral encephalitis; when cerebrospinal concentration was more than 0.384 ng/mL, S100b had a sensitivity of 93.3% and a specificity of 97.9%; a combination of the two indicators had a higher diagnostic value for viral encephalitis, with a sensitivity of 96.7% and a specificity of 97.9%.

CONCLUSIONSBoth NPT and S100b have certain values in the diagnosis of central nervous system infections in children, and S100b is better than NPT.

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52

0.05).In addition,in different medication intervals and the same total dosage(200 mg),there was no difference in the number of patients who reached ASAS20,ASAS50 anti BASDAI50 in both groups.The changes of other parameters were not observed.Conclusion Two dosages and different medication interval of rhTNFR-Fc have similiar efficacy onset time and maintenee period.Mean- while,at the same total dosage,there is no signifieant difference in therapeutic effect in the two dosage groups. However,50 mg(1/7 d)regimen has better compliance than 25 mg(1/3 d).

Objective To investigate the role of CD4~+CD25~+ Treg cells on the pathogenesis of ankylos- ing spondylitis(AS), and to study the machanism of tumor necrosis factor(TNF)-?blocker on the treatment of AS by detecting the number of CD4~+D25~+ Treg cells before and after the treatment. Methods The diagno- sis of 10 AS patients was made based on the 1984 modified New York criteria. The patients received subcuta- neou injection of recombinant human tumor necrosis factor receptor-Fc fusion protein(rhTNFR-Fc)(etaner- cept)50 mg weekly for 8 weeks and 10 heathy subjects were enrolled for control. The mononuclear cells were isolated from peripheral blood in beth patients and controls. The number of CD4~+CD25~+ T cells and CD4~+ CD25~(high)T cells and the expression of CTLA-4. were detected by flow cytometry. Results The proportion of CD4~+CD25~+ T cells(24?19)% in total CD4~+ T lymphocytes of peripheral blood and CD4~+CD25~(high)T/CD4~+ T (6?6)% from AS patients before treated with rhTNFR-Fc was higher than that in healthy volunteers and AS patients after treatment(P

Objective To explore the open experimental training model using multimedia control system for nursing students to develop their core competencies. Methods Different model designs of multimedia control system were applied in the study group. After the one year training program, a self-designed survey was used to collect the students' evaluation. A comprehensive test was carried out and the scores of it were compared to the traditional training group. Results Test sores of the study group was significantly higher than of the control group's (P<0.01), and the survey results showed that using multimedia control system in the open experimental training program was highly accepted by the nursing students (97.1%). Conclusions Using multimedia control system in the open experimental training program can improve the nursing students' competencies and comprehensive quality.

BACKGROUNDPopulation based epidemiologic study on the main diseases and birth status of liveborn neonates remains scarce in China, especially in rural areas where a large number of neonates are born. The aim of this study was to establish an epidemiological basis of live births in Julu County, a representative of the northern and mid-western parts of China in terms of demography, disease pattern and women and children's health care infrastructure.

METHODSThe perinatal data of all live births were prospectively collected in three participating county-level hospitals from September 1, 2007 to August 30, 2008.

RESULTSThere were 5822 live births in these hospitals. Among all live births, 53.7% were male and 4.5% were born prematurely. Mean (SD) birth weight (BW) was (3348 ± 503) g. The low (< 2500 g) and very low BW (< 1500 g) infants accounted for 3.8% and 0.5% of the total births, with 6.5% as small for gestational age and 2.8% as multi-births. Cesarean section rate was 30.2%, of which 68.6% were elective. There were 745 infants (12.8% of the live births) admitted to local neonatal wards within 7 days of postnatal life, in which 48.3% and 19.3% were due to perinatal asphyxia and prematurity, respectively. The incidences of perinatal aspiration syndrome, transient tachypnea and respiratory distress syndrome were 4.9%, 0.6% and 0.5%, respectively. Neonatal mortality was 7.6‰ (44/5822), with 16 in delivery room and 28 in neonatal ward before discharge.

CONCLUSIONSThis study provided a population-based perinatal data of live births and neonatal mortality in a northern China county with limited resources. Neonatal disorders related to perinatal asphyxia remain a serious clinical problem, which calls for sustained education of advanced neonatal resuscitation and improvement in the quality of perinatal-neonatal care.
