Objective To evaluate the current knowledge and practice of evidence-based nursing for preventing ventilator-associated pneumonia (VAP) and its influencing factors in ICU nurses. Methods Selfadministered structured questionnaire was used in 101 ICU nurses working in one grade three A hospital of Jiangsu province by convenient sampling method. The results underwent statistical description and variance analysis. Results The mean score of knowledge about evidence-based nursing to prevent VAP was (4.75±1.42) (total score=10),the mean score of practice was (3.32±0.32) (total score=4). The influencing factors of knowledge in ICU nurses were different divisions and ICU working years. Different ICU working years resulted in different behavior of nurses. Most nurses considered that nursing work was too busy due to serious condition of patients, which was the principal interfering factor in practice of evidence-based nursing for preventing VAP. Conclusions Further expertise of ventilator-associated pneumonia training and evidence-based nursing education are urgently required. The best-practice guidelines for preventing VAP are more often consummated. Whilst encouraging the reasonable personnel disposition and the essential facilities are priority. Effective fulfillmere in evidence-based practice to prevent VAP may be achieved by broader adjustment of the medical system and the medical cost structure, so that evidence-based nursing for preventing VAP can be put into effect.

Cardiac arrest (CA) is an acute critical illness with the high occurrence in the world. The directions of cardiopulmonary resuscitation (CPR) development are to improve CA patients' survival rate and to decrease the poor prognosis. β-blockers can selectively block the neurotransmitter or receptor agonists. They offer beneficial pharmacological properties and have been widely used in the treatment of cardiovascular diseases. Based on the search result of the domestic and foreign medical databases, the usage of β-blockers including clinical research, animal experiments and clinical work of CPR patients was summarized. Finally, the CPR research progress of β-blockers in recent years was reviewed in the article.

The outbreaks of Zika virus infection in different regions of the world underscore the potential for the virus to spread further in the Americas and beyond.Zika is a mosquito-borneFlavivirusand is transmitted by Aedes spp. mosquitoes.It is has been reported recently that Zika virus intrauterine infection causes fetal brain abnormality and microcephaly, and WHO encourages pregnant women in countries at risk MUST protecting themselves from mosquito bites. Until now, there is no imported case in China.We have established resource and technology storage to reply to the potentialZika cases in the future, therefore, people do not need to panic in China.

Objective:To establish the analysis method for the determination of Ni, Cu and Zn in aluminum food packaging mate-rials by inductively coupled plasma atomic emission spectrometry ( ICP-AES) . Methods: A small amount of EDTA was added to the test solution till the concentration at 0. 010 0 mol·L-1 and the pH value was adjusted to 5. 0. Strong acid cation exchange fibers were used for the assisted extraction of Al3+ with ultrasonic. Al3+ could not quickly form a complex anion with EDTA, so it was adsorbed by the strong acid cation exchange fibers. Cu2+, Ni2+ and Zn2+ could form complex anions with EDTA rapidly, so they could not be ad-sorbed by the strong acid cation exchange fibers and were left in the solution to be determined. Results:After the separation, the con-tents of Cu, Ni and Zn were not lost, and the content of residual aluminum was about 170 times of that of Cu, Ni and Zn, which had not interferece with the determination of Cu, Ni and Zn. The sample standard addition recovery was within the range of 98. 3%-104%with RSD of 0. 2%-2. 5%(n=5). The relative errors between the measured values and the certified values of standard substances were less than 5. 0%. Conclusion:The proposed method can be successfully applied in the separation and determination of Cu, Ni and Zn in aluminum cans, barbecue aluminum foil and standard substances.

Animal model plays an important role in prevention and control of infectious disease, which could link basic research in laboratory with clinical diagnosis and treatment for human patients.Mouse is the most widely used animal model of infectious disease, however, adult immunocompetent mice are resistant to some pathogens.The highly genetically diverse Collaborative Cross (CC) mice could recapitulate many of the genetic characteristics of an outbred population, such as humans.Based on this, this review will focus on the application and research progress of CC mice in infectious disease (including viruses, bacteria, fungi etc.), which could provide useful reference data for expansion of animal model resource bank, and implement of precision medicine of major and new emerging infectious diseases.We hope this review could serve as a modest spur to induce other researchers to come forward with their valuable contributions.

Objective To investigate the condition of self-management of patient controlled analgesia pump in patients in the ICU.Methods 82 patients in ICU were selected in July 2014 and were randomly divided into the observation group and the control group with 41 cases in each.In the observation group,the PCAP was fixed on the bedrails of patients' bed and controlled by themselves to acquire satisfactory analgesia effect.In the control group,the PCAP was operated by the nurses.Pains scores was compared between the two groups.Results The different position of PCAP showed the different scores of pain in the patients.The pain scores in the observation group (2.93±1.47) was significantly lower than that in the control group (3.76±1.36),P＜0.05.Conclusions Proper position of PCAP and controlled by patients can effectively reduce postoperative pain of patients in the ICU,and then reduce their suffering and improve their comfort.
