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.

Objective To report secondary paroxysmal sympathetic hyperactivity in a patient with tuberculous meningitis and to review the diagnostic criteria, clinical features, possible pathogenesis and management of this condition. Methods The clinical data of a case with paroxysmal sympathetic hyperactivity secondary to tuberculous meningitis was retrospectively analyzed and related literature was reviewed. Results A 1-year-old boy was admitted to our institute with a history of lethargy and vomiting for 3 days. Neurological examination revealed abnormalities. A lumbar puncture revealed the evidence of meningitis. PPD test, T-SPOT.TB and radiological examination revealed tuberculous meningitis. Later, when stayed in the intensive care unit, he developed paroxysmal hypertension, sinus tachycardia, tachypnea, dystonia, and high fever. These episodes improved after administration of propranolol, benzodiazepines and artane. Conclusions Paroxysmal sympathetic hyperactivity is a rare manifestation of tuberculous meningitis, early recognition is very important for avoid misdiagnosis and overtreatment.

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.

Escherichia coli AFP111 is a spontaneous mutant with mutations in the glucose specific phosphotransferase system (ptsG) in NZN111 (delta pflAB deltaldhA). In AFP111, conversion of xylose to succinic acid generates 1.67 molecule of ATP per xylose. However, the strain needs 2.67 molecule ATP for xylose metabolism. Therefore, AFP111 cannot use xylose due to insufficient ATP under anaerobic condition. Through an atmospheric and room temperature plasma (ARTP) jet, we got a mutant strain named DC111 that could use xylose under anaerobic condition in M9 medium to produce succinic acid. After 72 h, DC111 consumed 10.52 g/L xylose to produce 6.46 g/L succinic acid, and the yield was 0.78 mol/mol. Furthermore, the reaction catalyzed by the ATP-generating PEP-carboxykinase (PCK) was enhanced. The specific activity of PCK was 19.33-fold higher in DC111 than that in AFP111, which made the strain have enough ATP to converse xylose to succinic acid.
