Objective To investigate the influence of inspired oxygen fraction (FiO2) on the ratio of PaO2/FiO2(P/F) during the implementation of lung protective ventilation strategy in patients with acute respiratory distress syndrome(ARDS) in order to unravel its clinical significance. Method This was a prospective study of 16 selected patients with ARDS treated with mechanical ventilation ( MV ) to get ratio of P/F in range of 100 to 200 by PEEP≥5 cmH2O and high inspired oxygen. After lung recruitment maneuvers by BiPAP with high pressure (PH) of 40 cmH2O for40 s, the MV was maintained the basic requirement for stabilizing the patients for 30 minutes. A series of FiO2 were set at fractions of 0.5,0.6,0.7,0.8,0.9 and 1in random sequence, and the changes of respiratory mechanics, blood gas and hemodynamics under the different concentrations of FiO2 were analyzed by using SPSS version 13.0 software. Results ( 1 ) The ratio of P/F increased as FiO2 increased, and it's significant as FiO2 increased to 0.7 or above. As the fractions of FiO2 were set at 0.5 and 1. O, the ratios of P/F changed in 24.70% ± 23.36% respectively. ( 2 ) Of them,6 patients ( 37.5% ) treated with FiO2 set at 0.5 had the ratio of P/F ＜ 200, and the fraction of FiO2 was increased to 1.0, the P/F ＞ 200. (3) FiO2 and Qs/Qt were negatively correlated ( r = - 0.390, P = O. 027 ),the higher inspired oxygen fraction, the lower shunt. When the fractions of FiO2 were set at 0.5 and 1.0 ,there was a positive correlation between △Qs/Qt and △P/F( r = 0.82, P = 0.005 ). Conclusions The inspired oxygen fraction affects the ratio of P/F, which may be resulted from shunt and it may influence the diagnosis of ARDS.

Objective: To construct and characterize GFP-mfgl 2 fusion protein expression plasmid (pEGFP-mfgl 2) and provide a direct and simplified methodology for primary assessment of the effect of mfgl 2 siRNA on the mfgl 2 gene expression. Methods: mfgl 2 cDNA was amplified from the mfgl 2 cDNA library pBluescript-m166 (pm166) of mouse genomic P1 plasmid and recloned into pEGFP-N2 upstream of GFP gene. The pEGFP-mfgl 2 was analyzed by restriction endonucleases BamH I and Hind III to ensure the orientation and the sequence. This fusion plasmid was then transfected into CHO cells and the fusion protein expression was observed by fluorescent microscope. Rusults: A 1.3 kb long cDNA was obtained. Restriction endonucleases and sequencing assays showed the correct orientation and sequence. After 24-48 hours transfection in CHO cells, the expression of pEGFP-mfgl 2 can be visualized through fluorescent microscope. Conclusion: pEGFP mfgl 2 has been constructed successfully. The recombinant vector can express GFP-mfgl 2 fusion protein. It provides a direct and simplified methodology for primary assessment of the effect of mfgl 2 siRNA on the mfgl 2 gene expression.

Abstract?AIM: To discuss clinical efficacy and safety of 10g/L atropine with short covering for children with amblyopia.?METHODS: Eighty -eight children ( 88 eyes ) with amblyopia, staying in hospital from February 2011 to February 2014 for treatment, were divided into control group ( n =44 ) and observation group ( n =44 ) . The control group only given short covering therapy was observed.Observation group was given 10g/L atropine treatment besides covering.Clinical efficacy, treatment compliance, visual acuity, corrected spherical degree of amblyopia eye and adverse events were observed and compared.?RESULTS:1) After treatment, total effective rate of the observation group was 95% ( 42/44 ) , significantly higher than that of control group ( 80%, 35/44, P<0.05 ); 2 ) excellent compliance rate of the observation group was 95% ( 42/44 ) , significantly higher than that of control group (82%, 36/44, P<0.05);3) visual acuity of the two groups when the disease was first diagnosed was not significantly different (P>0.05), but increased number of lines of vision and corrected spherical degree of amblyopia eye in the observation group were significantly higher (P<0.05);4) in the observation group total rate of adverse events was 9% ( 4/44 ) , significantly lower than that in the control group (23%, 10/44, P<0.05).?CONCLUSION: The combined therapy, 1% atropine with short covering, is effective and safe for amblyopia in children.

The primary causative factors of liver failure include direct damage and immune -mediated liver injury.Increasing evidence sug-gests that immune -mediated injury plays a pivotal role in the pathogenesis of liver failure.The new concepts concerning the mechanisms of immune -mediated liver injury in liver failure are reviewed with relevant basic and clinical studies in both humans and animals.The innate and adaptive immunity,particularly the interaction of various immune cells and molecules,as well as apoptosis -related molecules,are dis-cussed in detail.

Despite different opinions on its definition and classification in the past,a consensus has gradually been reached regarding the na-ming,classification,and clinical diagnosis of liver failure.The classification of liver failure is described,and the definition and natural his-tory of severe exacerbation of hepatitis B are summarized.Antiviral treatment and artificial liver support in the early stage are beneficial for clinical outcomes and prognosis.

Objective To examine plasma levels of protease C1 inhibitor (SERPING1) in adult patients with latent autoimmune diabetes (LADA), and their clinical significance thereof. Methods The levels of SERPING1 were detected and compared between LADA, type 1 diabetes (T1DM), type 2 diabetes (T2DM) and healthy control groups. The correlation between plasma levels of SERPING1 and other clinical indicators such as age, disease course, glycosylated hemoglobin (HbA1c), fasting blood glucose (FPG), 2 h postprandial plasma glucose (2 hPG), fasting c-peptide (FCP) and 2 h postprandi-al C peptide (2 hCP) was analyzed. Multi-factor regression analysis and receiver operating characteristic (ROC) were used to evaluate the predictive effect of SERPING1 in LADA at the early stage. Results The level of SERPING1 was significantly higher in LADA group than that of T2DM group and control group (P < 0.05). There was a negative correlation between SERPING1 and FCP, and a positive correlation between SERPING1 and HbA1c, FPG and 2 hPG (P<0.05). There were no significant correlation between SERPING1 and age, disease course and 2 hCP. FCP was analyzed by regression equation (P<0.05), and which was the main influence factor of the plasma level of SERPING1. The area under the ROC curve (AUC) of SERPING1 was 0.613 (P<0.05), 95%CI 0.514-0.712. The optimal cut-point of SERPING1 for early prediction of LADA was 289.71 mg/L, and the sensitivity and specificity were 69%and 48%respectively. Conclusion SERPING1 combined with other indicators will be useful for identifying LADA from T2DM at the early stage.
