OBJECTIVETo investigate the mixed infection and analyze risk factors in children with severe adenovirus pneumonia.
METHODSA retrospective analysis was performed on the clinical data of 756 children with adenovirus pneumonia between June 2009 and June 2011. Pathogens and risk factors were studied in 216 severe cases.
RESULTSOf the 216 severe cases, 138 (63.9%) were aged from 6 months to 2 years, and 161 (74.5%) developed the disease in the winter and spring; 177 (81.9%) were affected by 1-4 pathogens besides adenovirus, including 74 cases (34.3%) infected with one pathogen as an addition. A total of 334 pathogen strains were identified from the respiratory secretions and sera of the 216 cases. Of them, 163 (48.8%) were bacterial strains, dominated by Gram-negative bacteria (124 strains), 108 (32.3%) were viral strains, and 40 (12.0%) were fungal strains. Multivariate logistic regression analysis indicated that congenital heart disease, congenital airway abnormalities, nutritional anemia, recurrent pulmonary infection, and surgical history were the independent risk factors for severe adenovirus pneumonia in children, with odds ratios of 3.3, 11.1, 7.2, 14.3 and 12.9 respectively (P<0.05).
CONCLUSIONSSevere adenovirus pneumonia is mostly seen in children aged from 6 months to 2 years and occurs frequently in the winter and spring. Many cases are also infected with other pathogens, most commonly Gram-negative bacteria. Congenital heart disease, congenital airway abnormalities, nutritional anemia, recurrent pulmonary infection and surgical history are the independent risk factors for severe adenovirus pneumonia in children.

This paper is to report the study of the pharmacokinetics of a fusion protein TAT-haFGF(14-154) for human acidic fibroblast growth factor and transcriptional activator protein in rat plasma, and the investigation of their penetration across blood-brain barrier in mice and rats, in order to provide a basis for clinical development and treatment of Alzheimer's disease. Enzyme-linked immunosorbent assay (ELISA) was used to determine concentration of TAT-haFGF(14-154) in rat plasma and in mouse brain homogenate; and immunohistochemistry was used to analyze the distribution in brain. The concentration-time curve fitted two-compartment open model which was linear kinetics elimination after a single intravenous injection of TAT-haFGF(14-154) in rat at the dose of 300 microg x kg(-1). The half life time was 0.049 +/- 0.03 h for distribution phase and 0.55 +/- 0.05 h for elimination phase, and the weight was 1/C2. The result showed that TAT-haFGF(14-154) could be detected in the brain by ELISA and immunohistochemistry, the elimination of TAT-haFGF(14-154) in rat was swift, and TAT-haFGF(14-154) could penetrate across the blood-brain barrier, distribute in pallium and hippocampus and locate in the nucleus.

BACKGROUNDThe acute abdomen remains a challenge for all obstetricians and physicians who take part in the care of women in pregnancy. To add substantially to our understanding of acute pancreatitis (AP) in pregnancy, in particular affirming the increased risks for mother and fetus associated with AP, we explored features of clinical manifestation and the strategy of management of this disease during pregnancy, and its effects on maternal and fetal outcomes.
METHODSA retrospective review of medical records of all pregnant patients diagnosed with AP admitted to the Department of Obstetrics and Gynecology, Sixth People's Hospital Affiliated to Shanghai Jiao Tong University between 2005 and 2010 was performed. Information was collected from presentation, management, and outcome from medical records.
RESULTSThere were 11 cases in 2010, accounting for 44% of 25 cases. Among these cases, mild AP (MAP) occurred in 15 cases (60%), while the rest cases were severe AP (SAP) (40%). The major etiology of AP in pregnancy was due to gallstone and cholecystitis. Clinical features together with elevation of the plasma concentrations of pancreatic enzymes were the cornerstones of diagnosis. Positive conservative treatment was taken in most of the cases (21 cases, 84%) with a favorable outcome. Seven cases of critically ill patients were monitored in intensive care unit, and 4 patients underwent surgical interventions. As a result, all of 25 patients had better prognosis, no maternal death was observed. There were 8 preterm labors and 2 fetal losses, accounting for the perinatal mortality of 8%. Fetal malformation was not observed.
CONCLUSIONSWhile a pregnant woman suffers acute abdominal pain, early diagnosis and severity assessment of AP are very important. Conservative comprehensive treatment with intensive care is recommended. Surgical intervention should be performed as late as possible.
