In order to carry out subject librarian service and improve electronic literature service in hospital libraries, the utilization of electronic literature databases in 240 clinical nurses of class A and B hospitals in Jinan, Qingdao and Jining was investigated with questionnaire, which showed the new features of clinical nurses in awareness and utilization of electronic literature databases under the new turn of hospital class evaluation.

OBJECTIVE:To observe clinical efficacy and safety of milrinone in the treatment of persistent pulmonary hyperten-sion of newborn. METHODS:52 newborns with persistent pulmonary hypertension were divided into control group and observa-tion group according to random number table,with 26 cases in each group. The control group were given mechanical ventilation and intravenous prostaglandin therapy. Observation group was treated with Milrinone injection at loading dose of 50 μg/kg,10 min intravenous injection,maintenance dose of 0.75 μg/(kg·min). Both groups received treatment for 48 h. Clinical efficacies of 2 groups were compared as well as SpO2,PaO2,OI,PAP,PAMP and SV before and after treatment. The occurrence of ADR was compared between 2 groups. RESULTS:Total effective rate of observation group was 92.31%,which was significantly higher than 80.77% of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in SpO2,PaO2,OI,PAP,PAMP and SV levels between 2 groups(P>0.05). After treatment,above indexes of 2 groups were im-proved significantly;SpO2,PaO2,OI and SV levels of observation group were significantly higher than those of control group, while PAP and PAMP levels were significantly lower than those of control group,with statistical significance(P<0.05). No obvi-ous ADR was found in 2 groups. CONCLUSIONS:Milrinone shows significant therapeutic efficacy in the treatment of persistent pulmonary hypertension of newborn,and can significantly improve persistent pulmonary hypertension and increased oxygen con-tent of blood with good safety.

Objective To assess the safety of living environment by the elderly, further clarify the relevant factors of the elderly fall in the living environment. Methods The self- made assessment form of fall-related factors of living environment for elderly patients was used to survey 1 076 elderly. Likert five grades score was used for each item, and the higher score demonstrated the safer living environment. Results In the assessment of the safety of living environment, the indoor physical environment (3.94 points), home furniture safety (3.66 points) score was better;home ground and the channel (3.32 points) and outdoor activities places (3.57 points) score was lower. Scores of home′s ground and channel, furniture safety, indoor physical environment and living environment of urban elderly were (23.56 ± 6.49), (44.52 ± 7.72), (11.93 ± 2.49), (105.03 ± 17.82) points, which were better than (22.46 ± 6.39), (42.73 ± 7.95), (11.53 ± 2.39), (101.55 ± 18.15) points of rural elderly (t=2.471-3.495, P <0.05). Conclusions The indoor physical environment, home furniture safety got higher scores, and the scores of ground-channel environment and outdoor activities places were relatively lower. Scores of the safety of living environment in urban are better than in rural. It suggests the elderly living environment need to reduce the incidence of falls.

OBJECTIVE:To evaluate the feasibility of using CYP2C19 gene to guide the use of antiplatelet agents in acute cor-onary syndrome(ACS)patients undergoing interventional operation in China from the viewpoint of pharmacoeconomics. METH-ODS:Based on global PLATO trial data,the patients were divided into 3 groups according to treatment strategies(clopidogrel group,ticagrelor group,genetic test group). By applying Treeage Pro 2011 software,short-term decision tree model and long-term Markov model were established,and related data were imported to evaluate cost-effectiveness of different treatment strategies. RE-SULTS&CONCLUSIONS:For ACS patients,according to the level of GDP in China,conventional use of ticagrelor is of pharma-coeconomic advantage for in Shanghai and uninsured patients insured patients;the use of antiplatelet agents guided by CYP2C19 gene test is of pharmacoeconomic advantage among nationwide insured patients.

Word frequency and co-word analysis of key words and comparative analysis of hot spots and topics in core journals-published papers on health policy in China from 2004 to 2008 and from 2009 to 2013 showed that health policy research and health system reform promoted each other and developed with each other, the research tipics on health policy were scattered and expanded rapidly , the focus of researches was more clear with stress laid on their macro-aspects, and the research methods were variable.
