Objective To investigate the predictive value of peripheral blood neutrophil to lymphocyte ratio(N/L ratio) in patients with hypertension.Methods A total of 660 cases hypertension patients were enrolled from May 2013 to May2014.Peripheral blood N/L ratio was recorded.All patients were followed up to May 31,2016.According to the incidence of cardiovascular and cerebrovascular events,all patients divided into observation group(with cardiovascular and cerebrovascular events) and control group(without cardiovascular and cerebrovascular events),and white blood cell classification was compared.Logistic regression model was used to evaluate the value of N/L to predict cardiovascular events.Results The incidence rates of smoking,diabetes and hyperlipidemia in patients of the observation group were 87.5%,72.5% and 77.5%,higher than those of the control group(P<0.05),and the level of mean arterial pressure(MAP) was(95±12) mmHg,significantly higher than the control group(P<0.05).White blood cell count,percentage of neutrophils,mononuclear cell count,N/L of observation group were(11.6±2.5)×109/L,(70.8±5.9)%,(8.3±5.5)% and 3.7±1.5 were higher than control group(P<0.05).N/L increased by 10%(P=0.04),MAP increased by 10 mmHg(P=0.02) and the proportion of neutrophils(N%) increased by 15%(P=0.03) were independent risk factors for death in patients.Conclusion Neutrophil/lymphocyte ratio and mean arterial blood pressure were independent risk factors for hypertension patients with West-to-cerebral vascular events.

After a descrption of the background of patron-driven acquisition ( PDA) or demand-driven acquision (DDA) and its short-term loan model, purchase model, auto-purchase model, librain-purchase model, and evi-dence-based acquisition model, the total amount of resources in common PDA platform, PDA models and their users were analyzed.The key problems in PDA implementation were pointed out, such as formulation of criteria for the development of resources, control of funds, mangement of MARC data, and assessment of PDA project, and sug-gestions were put forward for their solution .

It is the responsibility of the society to improve the health literacy of residents and the public health-o-riented popular science information service is a rather effective measure to improve the health literacy of residents. However , the public health literary is rather low and the public health-oriented popular science information service is far behind satisfaction. The ways and key factors were thus put forward for public health-oriented popular science information service in medical library by analyzing the advantageous medical information resources, advanced tech-nical equipments and professional staff in medical library.

Objective To explore the postoperative secondary xerostomia′s uncomfortable experience of patients with long fating in gastrointestinal surgery, providing basis for medical staff to understand comfort needs of patients and to take targeted nursing intervention. Methods The phenomenological methodology was used in the study. Totally 12 patients with postoperative secondary xerostomia′s uncomfortable experience were interviewed, and tape recording was used. The data was analyzed by Colaizzi analysis method. Results Four themes were extracted: emotional response to patients with postoperative xerostomia, uncomfortable experience of mouth, the insufficient cognition of fating in perioperative period, desire for attention to solve the problem of dry mouth. Conclusions Medical staff should strengthen the awareness of the patients′experience with secondary and temporary dry mouth, and improve the nursing intervention measures according to need, in order to increase patients′comfort and to promote them recover soon.

The extended service in domestic and foreign medical libraries was summarized according to the trans-formation of medical library and the need of public health information followed by a description of some typical cases of extended service provided by MedlinePlus website , Disaster Medical Information Management Research Center , and patient libraries in order to provide the reference for domestic medical libraries to cary out their extended service .

After the significance to asses the value of information resources in hospital library was elaborated, the methods to assess the value of information resources in hospital library were constructed by contingent valuation and investment return analysis in combination with the practical service in hospital library according to the analysis of the economic value assessment in domestic and foreign public libraries and academic libraries.
