Mechanical ventilation plays an important role in the treatment of preterm infants,especially respiratory problems.With improvement in both antenatal and neonatal care and therapeutic strategies,premature babies are surviving more than ever.However,the incidence of bronchpulmonary dysplasia remains high which affects the clihical outcomes of premature infants.Non-invasive respiratory support techniques have been used in attempts to decrease lung injury and the complications of preterm infants.This review will focus on various ventilation modalities for managing preterm infants with respiratory failure and lung protective ventilation strategies to minimize lung injury in preterm infants.

To analyze the EBM present situation of the medical staffs and to discuss the measures to raise the ability of EBM so as to promote the performance of EBM.

Objective To establish a quality standard for Tibetan medicineRuyi-Zhenbao pill. Methods Thin-layer chromatography (TLC) was applied to identify 12 Tibetan medicinal materials, and High performance liquid chromatography (HPLC) was employed to determine the contents of gallic acid, dehydrodiisoeugenol, piperine, and cinnamaldehyde.Results The identified characteristics of TLC were distinct and the spots were clear. Linearity of gallic acid, dehydrodiisoeugenol, piperine, and cinnamaldehyde were in the range of 0.106-0.901μg, 0.033-0.281μg, 0.007-0.060μg, and 0.021-0.178μg, respectively. Average recovery was in the range of 98.47%-101.65% (RSD<3.0%).Conclusions The method of identification and content determination was good in terms of specificity, accuracy and repeatability, and can be used for quality control ofRuyi-Zhenbaopill.

Objective To investigate the differences of background in anxiety neurosis and obsessive－ compulsive disorder,and their suicide rate and comorbidity.Method 68 anxiety neuroses and 62 obsessive－ compulsive disorders were investigated by the selfconstructed scule.Rusult Age of onset,style of onset,marriage and education were significantly differences between anxiety neurosis and obsessive－ compulsive disorder(P< 0.01～ 0.001).The rates of suicide behavior and suicide intent in anxiety neurosis and obsessive－ compulsive disorder were 10.3％ and obsessive－ compulsive disorder with depressive disorders were 70.6％ and 35.5％ respectively.Conclusion Anxiety neurosis and obsessive－ compulsive disorder two different disorders,they had higher suicide rates and comorbidity.

Cellulase system contains a series of complex components.There are still some problems remained unclear in cellulase and its mechanism of hydrolyzing lignocellulosic materials and its hydrolysis kinetics,so profound study is needed.The rapid development of many kinds of new interdiscipline such as biochemistry,molecular biology and gene engineering,has further clarified the structure and function of cellulase,and the relationshi Pof its gene expression and regulation,and furthermore resulted in derivative study methods about cellulase in more aspects.Cellulase system components according to synergistic catalytic mode and the sequence of the homology amino acids similarity,summarizes traditional detection methods of enzyme components,and emphasizes on research progress of various biosensors applied in detection of cellulase activity and gene expression was introduced.

Objective To evaluate the correlation between serum procalcitonin concentration and systemic inflam-matory response syndrome (SIRS)score in patients with bacterial bloodstream infection.Methods In January-De-cember,2012,96 patients with bacterial bloodstream infection in a hospital were selected as trial group,and these patients were divided into three groups(group A,B and C)according to SIRS score;84 patients without bacterial in-fection was as control group,PCT concentration of all patients were detected,and the correlation between PCT con-centration and SIRS score was analyzed.Results Among 96 patients with bacterial bloodstream infection,7 (7.29%)died (4 were in group B and 3 in group C);there was no death case in control group.PCT concentration in control group,group A,B and C of trial group were (0.28±0.09)ng/mL,(0.63±0.13)ng/mL,(3.68±1.01)ng/mL,and(7.45±1.53)ng/mL,respectively,the difference between each group was significant(P<0.01).Pairwise comparison of four groups showed statistical difference (P<0.001).Spearman correlation analysis on PCT concen-tration and SIRS score was conducted,correlation coefficient r=0.874(P<0.001)suggested positive correlation be-tween serum PCT concentration and SIRS score.Conclusion PCT concentration in patients with bacterial blood-stream infection and SIRS score is positively correlated,PCT concentration and SIRS score can be used as two mark-ers for assessing the extent and prognosis of bacterial bloodstream infection.

Objective To explore the feasibility and significance of using ventilated technology of oxygen after unchaining in assistant breathing equipment cycled with mixed gases of helium and oxygen.Methods After giving out the relative increment matrix for keeping the system steady,the paper introduces the detail methods for the control of oxygen concentration after unchaining coupling in assistant breathing equipment cycled with mixed gases of helium and oxygen.Results It shows that the control of oxygen concentration after unchaining coupling is a vital technology in assistant breathing equipment cycled with mixed gases of helium and oxygen.
