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.

Objective To evaluate the prophylactic effect of pancreatic duct stent (PPDS),NonSteroid Anti-Inflammtory Drugs (NSAIDs),and joint PPDS and NSAIDs on post endoscopic rectrograde cholangiopancreatography(ERCP) Pancreatitis(PEP) in choledocholithiasis patients.Methods A total of 200 choledocholithiasis patients were randomly divided into 4 groups,prophylactic pancreatic duct stent(PPDS) group (A),NSAIDs group (B),joint PPDS-NSAIDs group (C) and routine ERCP without prevention for PEP(group D).VAS score,levels of amylase in serum and CRP were measured before and 4 h,24 h,48 h after ERCP.Incidences of hyperamylasemia and PEP were observed.Results (1) Incidences of hyperamylasemia 48 h after ERCP were 6％ (3/50),6％ (3/50) and 4％ (2/50) in group A,group B and group C respectively,which were significantly lower than that of group D (11/55) (P ＜ 0.05).(2) Incidences of PEP 48 h after ERCP were both 2％ (1/50) in group A and group C,which were lower than that in group D (10％,5/50,P ＜ 0.05).Group B (4％,2/50) was lower than that of group D but there was no statistical significance(P ＞0.05).(3) VAS scores of all groups at 4 h,24 h and 48 h after the operation were significantly higher than before (P ＜ 0.05).Group B score was significantly lower than that of group D (P ＜ 0.05).Scores of group A and C at 4 h were lower than those of group D (P ＜ 0.05),and those at 24 h and 48 h were also lower but with no statistical significance (P ＞ 0.05).(4) Serum CRP levels at 4 h,24 h and 48 h were significantly higher than those before in each group.Serum CRP levels of group B and C were significantly lower than that of group D at 4 h,24 h and 48 h.Serum CRP level of group A was significantly lower than group D at 4 h,24 h.CRP level at 48 h of group A was lower than that of group D,but there was no statistical significance (P ＞ 0.05).Conclusion Both prophylactic pancreatic duct stent and NSAIDs (Parecoxib Sodium) can reduce incidence of hyperamylasemia after ERCP common bile duct lithotomy.Single or joint use of prophylactic pancreatic duct stent can prevent PEP.Furthermore,prophylactic pancreatic duct stent and NSAIDs (Parecoxib Sodium) can reduce pain and inflammation after ERCP common bile duct lithotomy.NSAIDs only (Parecoxib Sodium) is more effective than prophylactic pancreatic duct stent only and joint use of both.

AIM: To explore curative effect of different drugs in treatment of senile wet macular degeneration.METHODS: We selected 98 patients 98 eyes with senile wet macular degeneration from July 2014 to January 2016 in our hospital as the research subjects.They were divided into control group and research group as the administration sequence, 49 patients in each group.Research group was treated with ranibizumab.The control group was treated with Conbercept.Both once per month and for 3mo.RESULTS: Uncorrected visual acuity, central macular retinal thickness and area of choroidal neovascularization (CNV) leakage before treatment of the two groups were not statistically different (P>0.05).At 1, 3 and 6mo after treatment, the uncorrected visual acuity was improved significantly, the central macular retinal thickness decreased significantly, and the area of CNV leakage decreased significantly (P<0.05).The differences on uncorrected visual acuity at 1mo after treatment, central macular retinal thickness and area of CNV were statistically significant (P<0.05), while those indexes at 3 and 6mo after treatment was not significant (P>0.05).In the follow up period, there was no severe complications in the two groups, such as persistent high intraocular pressure, retinal detachment or tear, endophthalmitis, or other systemic complications.There were subconjunctival hemorrhage in 10 eyes in research group, 8 eyes in control group, all of which recovered within 15d after treatment.Transient elevated intraocular pressure occurred in 7 eyes in research group, in 9 eyes in control group.The complication rates of the two groups were not significant (P>0.05).CONCLUSION: In the clinical treatment of senile patients with wet macular degeneration, treatment effect of Conbercept is not obvious at the early stage, but the effect is equivalent later and more economical.
