Objective To explore the effect of negative pressure attraction method of brushing and washing apply in oral care of patients with orotracheal intubation.Methods Totals of 82 oral intubation patients in ICU were randomly selected and divided into experience group ( n =42 ) and control group ( n =40 ).The traditional method of oral care was used in control group,while the negative pressure attraction method of brushing and washing was used in experience group,then,the incidence of oral infections,ventilator-associated pneumonia( VAP),dental plaque and oral mucosal injury were observed in two groups.Results The incidence of oral infections,ventilator-associated pneumonia(VAP),dental plaque in experience group respectively were 7.14％,2.38％,4.76％,and that in control group were 22.50％,15.00％,32.50％,the differences were statistically significant ( x2 =3.88,4.18,10.55,respectively; P ＜ 0.05 ),while there was no significant difference in the incidence of oral mucosal injury between two groups ( P ＞ 0.05 ).Conclusions The negative pressure attraction method of brushing and washing can effectively keep the oral clean of patients with orotracheal intubation,reduce the incidence of oral infections and ventilator-associated pneumonia and dental plaque,when compared with the traditional method of oral care.

Objective To construct two lentiviral eukaryotic expression vectors of pEGFP-N1-HIF-1α and pEGFP-N1-muHIF-1α and identificate the gene sequences.Methods Primers were designed according to wild-type human HIF-1 α gene sequence information and determined restriction sites of human HIF-1α point mutant sequence,taking human HIF-1α and constructed HIF-1α gene mutant clone as a template for polymerase chain reaction(PCR) amplification.Then,the target gene PCR product and purpose vector were digested.Adapter-ligated fragments of the target fragment with purpose vector were transformed into DH-5α competent cells using the recombinant PCR methods.Finally,the positive clones were selected and sequenced to verify whether the sequence of insert fragments in recombinant clones was consistent with oligo sequences designed or not.Results Through recombinant clone colony PCR,enzyme digestion of the recombinant clones and plasmid cloning and sequencing,the fragment sequences inserted in recombinant clones were consistent with the designed oligo sequences.Conclusions The two lentiviral eukaryotic expression vectors of pEGFP-N1-HIF-1α and pEGFP-NI-muHIF-1α were successfully constructed and applicable for follow-up experiments on transfection of bone marrow mesenchymal stem cells.

OBJECTIVETo investigate the temporal changes of serum interleukin-37 (IL-37) concentration following acute ST-segment elevation myocardial infarction (ASTEMI) and the relationship between IL-37 and C-reactive protein (CRP) in patients with ASTEMI.

METHODSThis analysis was conducted in a cohort of 20 patients with an established diagnosis of ASTEMI and 26 patients admitted for chest pain but with normal findings in coronary angiography (control) between June 2012 and December 2013. Venous blood was collected at days 1, 3, 5, and 7 after myocardial infarction for measurement of serum IL-37 and CRP levels using enzyme-linked immunosorbent assay (ELISA).

RESULTSCompared with the control group, the patients in ASTEMI group showed a significant acute elevation of IL-37 level on day 1 following myocardial infarction; IL-37 level reached the peak on day 3 and began to decrease on day 5, followed by a significant decrease on day 7. The time course of post-infarction CRP changes was consistent with that of IL-37 variations and showed a positive correlation the latter (r=0.63, P<0.05).

CONCLUSIONIL-37 may participate in the inflammatory responses in ASTEMI.
