Chinese Journal of Primary Medicine and Pharmacy 2011;18(z1):7-8
Objective To discuss the clinical preventation and treatment of the complications induced by endotracheal intubation in SICU.Methods Retrospective analysis was used on 55 cases of intubated patients in our hospital nearly 2 years.Results The incidence of endotracheal intubation was 36.4%,pneumonia 23.6%,accidental extubation 5.5%,endotracheal ulcer 1.8%,tracheoesophageal fistula 1.8%,obstruction of tracheal catheter 1.8%,arytenoid dislocation 1.8%.Conclusion The causeof complications of endotracheal intubation in SICU were overtime intubation,tranma,excessive-pressure of the air cuff and local inflammation.Airway humidification,suitable sedation,accurate and moderate operation,extubation or tracheotomy,suitable cuff pressure and fiberoptic bronchoscopy examination could avoid such complications.

Objective:To prepare and purify recombinant human zona pellucida 3 protein,and to study its immunologic activity.Methods:The E.coli BL21 containing recombinant plasmid pGEX4T-1/ huZP3 was induced to express GST-fusion protein by IPTG.After a series of purification procedure,the purified protein was analyzed by SDS-PAGE.After the mice immunized with rhuZP3,the antibody responses against rhuZP3 were detected by ELISA.Results:The soluble fusion protein was expressed,and purity of rhuZP3 was 95%.Moreover, purity of rhuZP3 could be recognized by anti-human ZP3 in ELISA.Conclusion:The rhuZP3 is obtained through the preparation of prokaryotic expression system and anti-rhuZP3 antibody has immunological activity.

Objective To construct a novel VP 1 gene vaccine against coxsackievirus B 2 and to evaluate the effect of the cell-mediated immunity induced by it.Methods The immunodominant capsid protein VP 1 gene of CVB 2 was amplified by reverse transcript polymerase chain reaction (RT-PCR) and pcDNA 3-CVB 2VP 1was constructed by molecular cloning.The cytotoxic T lymphocyte (CTL) activity was measured by standard 51Cr-release cytotoxicity assay eight weeks after BALB/c mice were immuned by pcDNA 3-CVB 2VP 1.Results The eukaryotic expression vector was pcDNA 3 and subcloning fragment was CVB 2VP 1.The CTL activity of pcDNA 3-CVB 2VP 1 group was higher than that of the control (P

Objective To observe changes of hemodynamics and regional cerebral blood flow(rCBF) in patients with Leukoaraiosis(LA) and to investigate the pathogenesis of LA.Methods 67 patients with LA were examined by Transcranial Doppler(TCD). Regional cerebral blood flow was detected by SPECT in 19 of 67 patients.Results The medium blood flow velocities(Vm) of internal carotid artery system in LA(included mild, moderate and severe group) were significantly decreased compared with the controls( P

Objective To investigate the changes of serum endotoxin and its receptor CD 14 gene expression in multiple organs in models of acute forebrain ischemia complicated with multiple organ dysfunction syndrome (MODS), and the pathogenesis of cerebrogenic multiple organ dysfunction syndrome (CMODS). Methods 54 Wistar rats were randomly divided into normal control group ( n=6), sham-operative group ( n=8) and forebrain ischemic group ( n=40). The rats in forebrain ischemic group were randomly divided into 5 subgroups: 12, 24, 36, 48, and 72 h (8 rats in each group). The contents of endotoxin in plasma were determined after models of acute forebrain infarction established. The area density and optical density of positive staining expressing CD 14mRNA in lung, liver, intestine and kidney were analyzed for the relative content of CD 14mRNA using in situ hybridization and CMIA medical image analysis system.Results Plasma endotoxin level was markedly high at 12 hours after acute forebrain ischemia, peaked at 24 hours and somewhat decreased at 72 hours. The CD 14mRNA expression in lung, liver, intestine, and kidney tissues increased after brain ischemia, reached the peak at 24~36 h, and decreased after 48 hours. The highest change of CD 14mRNA expression was found in lung ( P
