Objective To investigate the effects of Kr üppel-like factor 2 ( KLF2 ) on oxidized low density lipoprotein (ox-LDL) induced expression of microRNA-146a (miR-146a) and proinflammatory cyto-kines (MCP-1 and IL-6) in human umbilical vein endothelial cells (HUVECs).Methods Human umbili-cal vein endothelial cells (HUVECs) were cultured and then stimulated with 50μg/ml ox-LDL for 24 hours. HUVECs were infected with adenovirus vectors over-expressing human KLF2 at an appropriate multiplicity of infection.KLF2-siRNA duplexes were transfected into HUVECs to silence the gene expression .HUVECs were collected at time points of 0 h, 3 h, 6 h, 12 h, 24 h and 48 h after infection.Real-time quantitative-PCR was performed to measure the expression of miR-146a at mRNA level.Silenced endogenous miR-146a using LNA-anti-miR-146 a was transfected into HUVECs with lipofectamine 2000 .The levels of MCP-1 and IL-6 in supernatants were detected by ELISA .Results KLF2 remarkably inhibited the expression of miR-146 a in unstimulated and ox-LDL-stimulated HUVECs in a time-dependent manner .The ox-LDL induced ex-pression of miR-146a, MCP-1 and IL-6 in HUVECs were significantly decreased by KLF2.Silenced expres-sion of miR-146a downr-egulated the ox -LDL induced expression of MCP-1 and IL-6 in HUVECs.Moreover, silenced miR-146 a could partly reverse the inhibitory effects of KLF 2 on ox-LDL induced expression of MCP-1 and IL-6 in HUVECs.Conclusion KLF2 inhibited ox-LDL induced expression of MCP-1 and IL-6 in HUVECs partly through down-regulating the expression of miR-146a.

Objective To monitor the changes of resting energy expenditure in ventilated critically ill children,to compare the results of standard equations and indirect calorimetry (IC) in predicting energy expenditure,and to investigate the possible influence factors of the metabolic status of the critically ill children.Methods From September 2012 to September 2013,56 critically ill children on assisted ventilation and fitting the requirements of IC in pediatric intensive care unit of Shanghai Children's Medical Center were enrolled in this prospective study.IC measurements were performed using metabolic cart on day 1,4,7,10 after trachea intubation.General clinical data of these children were recorded.Results 130 IC measurements were performed in the 56 children.The measured resting energy expenditure (MREE) did not exhibit significant differences among day 1,4,7,and 10 (P =0.379).Although there were no significant differences between MREE and energy expenditure predicted with Schofield and WHO equations (P =0.917,P =0.995),the agreement was poor between the measured and predicted values (R2 =0.185,R2 =0.322).The metabolic status of the children on day 1 of ventilation was only correlated with age (P =0.000) and height (P =0.027),not with severity of underlying diseases or clinical outcomes.Conclusions MREE of IC method in ventilated critically ill children did not significantly change over time in this study.A poor agreement was observed between equationpredicted energy expenditure and MREE.IC measurement of resting energy expenditure is recommended for guiding individual nutritional support among critically ill children so as to improve clinical outcome.

Objective To analyze the risk factors of mucous plug caused byMycoplasma pneumoniae pneumonia (MPP) in children and guide clinical therapy to decrease the incidence of sequela caused by airway inlfammatory obstruc-tion.Methods We conducted a retrospective study of the clinical data of 116 children with MPP who received ifber broncho-scope from January 2012 to January 2014 admitted to the respiratory department of the Children's Hospital of Hebei provience. Based on the airway mucosal lesions seen through the bronchoscope, the subjects were divided into the mucous plug group (n=67) and the control group (n=49). Gender, age of onset, febrile course, pleural effusion, white blood cell counts, neutrophil ratio, C reactive protein (CRP), serum lactate dehydrogenase level (LDH), initial time of received macrolides and ifber bronchoscope were compared between the two groups. If the Results of single factor analysis showedP<0.05, the indicators were analyzed by the logistic regression analysis. The receiver operator characteristic (ROC) curve was drawn to evaluate the predictability of logistic regression model.Results The Results of single factor analysis showed that age of onset, febrile course, CRP, serum LDH, pleural effusion cases in the mucous plug group were higher than those in control group (P<0.05). The Results of the logis-tic regression analysis showed that older than three years (OR=7.45), febrile course more than 10 days (OR=4.01), the level of CRP and LDH higher than 40 mg/L (OR=5.41) and 350 U/L (OR=3.63) were respectively the risk factors of mucous plug caused by MPP in children. The area under the ROC curve is 0.846 (95%CI: 0.773-0.919,P=0.000).Conclusions MPP children with age older than three years, or with febrile course more than 10 days, or with the level of CRP and LDH higher than 40 mg/L and 350 U/L has the possibility of forming a mucous plug.

A sensitive method based on high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed for the simultaneous determination of folic acid (FA) and its active metabolite, 5-methyltetrahydrofolic acid (5-M-THF), in human plasma. The analytes were extracted from plasma with methanol solution containing 10 mg/mL of 2-mercaptoethanol and 0.025% (v/v) ammonium hydroxide. FA and 5-M-THF were more stable after the addition of 2-mercaptoethanol and ammonium hydroxide in the sample preparation procedures of this study than they were in the previously published methods. Chromatographic separation was performed on a Hedera ODS-2 column using a gradient elution system of acetonitrile and 1 mM ammonium acetate buffer solution containing 0.6% formic acid as mobile phase. LC-MS/MS was carried out with an ESI ion-source and operated in the multiple reaction monitoring (MRM) mode. The assay was linear over the concentration ranges of 0.249-19.9 ng/mL for FA, and 5.05-50.5 ng/mL for 5-M-THF. The developed LC-MS/MS method offers increased sensitivity for quantification of FA and 5-M-THF in human plasma and was applicable to a pharmacokinetic study of FA and 5-M-THF.
