Objective To explore the relationship between plasm level of vascular endothelial growth factor (VEGF) and children Anaphylactoid purpura(AP).Methods The concentrations of VEGF in serum were detected with enzyme-linked immunosorhent assay in twenty four children with AP,twenty four children with APN in acute phase and twenty four healthy children.Results The concentrations of VEGF in patients with APN in acute phase,AP and normal control was (244.56±51.12)μg/L,(155.71±50.48)μg/L and (54.91±40.07)μg/L,respectively.Plasma levels of VEGF in children with APN and AP were significantly higher than those in normal control,statistically significant difference was observed (F=95.789,P=0.000＜0.01).Conclusion The concentrations of VEGF in serum increases markedly in acute phase of AP,those in APN is higher than in AP.It indicated that VEGF involved in the occurrence and development of AP vaseulitis,and may reflect the extent of pathogenetic condition.

Objective To investigate the method for the treatment of haemorrhage of all ventricles.Methods 46 cases were treated by continuous extrinsic drainage through puncture of the lateral ventricle which accumulated more blood combming with substitution of CSF by meams of lumbus puncture per day.Urokinase was injected into ventricle at regular intervals.Results The symptoms were improved.Head CT were reexamined in 41 cases,which showed disappearance of hematocele in ventricle within 4～15 days.Except for 5 cases of death,other cases recovered from the disease.Conclusion The hematocele above and below the duct in ventricle can be eliminated by this method,and the mortality rate can reduced greatly and the quality of survival can improved.

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

Objective To investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI), and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods A total of 231 hospitalized children with acute LRTI were investigated from May 2013 to April 2014. The 5 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction, including respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV) and rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific immunoglobulin E level measured using immunofluorescence experiment was over 0.35 IU/mL. Results RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infections were more prevalent in asthma exacerbations compared to other LRTIs. AV was more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.

Objective To identify the risk factors for severe acute lower respiratory infections (ALRI) in children and to provide scientific basis for prevention and treatment of ALRI. Methods Several databases including Pubmed, Databases-Medline (Ovid), Embase, CINAHL and Global Health Library, CNKI, VIP and Wanfang Date were searched (1990.1-2014.12) for references. All selected studies were about risk factors of ALRI in children. The screening and quality evalua? tion of the literature data was conducted independently by two reviewers according to the inclusion and exclusion criteria. Stata 11.0 software was used for Meta-analysis. Results Meta-analysis of 27 included literature showed that seven risk fac?tors were significantly associated with severe ALRI:low birth weight, lack of exclusive breastfeeding, crowded household, ex?posure to indoor air pollution, malnutrition, living in a house with smokers or smoking in pregnant and HIV-exposed unin?fected condition. Conclusion The above seven risk factors play the important role in the development of ALRI in children. Furthermore, it emphasizes the need for further studies investigating other potential risk factors to decrease the possibility of childhood ALRI.

BACKGROUND:Bacterial adhesion is closely related to the surface properties of cobalt-chromium al oys, and therefore, the surface modification technology has become the focus of research in this area. OBJECTIVE:To verify whether the cobalt-chromium al oy with zirconium nitride coating can improve the bacterial adhesion of metal denture materials. METHODS:Magnetron sputtering deposition method was used to plate zirconium nitride film on the surface of cobalt-chromium al oys (experimental group), and cobalt-chromium al oy specimens uncoated served as control group. Streptococcus mutans, Candida albicans, and Actinomyces viscosus were respectively inoculated on the two kinds of test specimen, and at end of culture, the colony counting was done. RESULTS AND CONCLUSION:In the bacterial adhesion test, the number of colonies of three kinds of bacteria in the experimental group was significantly lower than that in the control group (P<0.05). The number of bacterial adhesion in the control group was significantly higher than that in the experimental group. These findings indicate that the cobalt-chromium al oy covered with zirconium nitride coating can significantly reduce the adhesion amount of Streptococcus mutans, Candida albicans and Actinomyces viscosus, and thus improve bacterial adhesion properties of cobalt-chromium al oys.
