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.

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 explore the methods of inducing human placenta mesenchymal stem cells (MSCs) to differentiate into insulin-producing cells. Methods MSCs were obtained from human placenta and were induced to differentiate into insulin-producing cells by activin A, epidermal growth factor (EGF), basic fibroblast growth factor (bFGF) and other cytokines. The cells were identified by immunocytochemistry staining, Western Blot and animal experiment after differentiation. Results After induction, the cells possessed some characteristics of islet βcells, and could express pancreatic duodenal homeobox-1 (PDX-1), insulin and C peptide. The induced cells could also decrease blood glucose levels of diabetic mice. Conclusions These results showed that human placenta MSCs can be induced to differentiate into insulin-producing cells by cytokines.
