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 analysis the genetic context of armA gene identified in different species .Methods BLASTN searches were used to analysis sequences harboring armA submitted to the GenBank database .Results armA gene was mostly found down-stream of ISCR1 element and was most commonly detected in Enterobacter spp ..Its flanking sequences were highly conserved in Enterobacter spp ..Conclusion The genetic context of armA gene reported in different species scattered in different geometrical lo-cations share some common characteristics .

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.

The data of 162 cases with acute schistosomiasis in Jingzhou City from 2004 to 2008 was analyzed, and the resultsshowed that the endemic situation of acute schistosomiasis decreased year by year, and the children aged 5-14 years were themain infection population, and swimming and playing in water was the main infection mode. It is suggested that health educationfor residents especially students should be strengthened to improve their conscious for disease prevention.

Objective To evaluate the efficiency of different wash methods for removing organophosphorus pesticide residues from cucumber. Methods The cucumber samples were soaked with tap water, washed rice water, salt solution and detergent solution respectively for 2 to 15 minutes then organophosphorus pesticide residues in the soak water samples were determined with ultrasonic extraction and gas chromatography. Results Soaked in tap water for 2 to 5 minutes was the most effective and convenient way to remove methamidophos and dimethoate with the highest removing rate (about 70%). Conclusion Soaked with tap water for 2 to 5 minutes is more efficient for removing organophosphorus pesticide residues from vegetable.
