Objective To construct a self-assessment system of patient safety by nurses.Methods Using self-designed questionnaires of self-assessment system of patient safety by nurses,29 nursing safety management experts were selected.Delphi method was adopted to carry out two rounds of interview.The self-assessment system of patient safety by nurses was built.The importance of the indicators went on weight analysis with specialist sorting.Results The system included 3 first-level indicators,9 secondlevel indicators,48 third-level indicators.The coefficient of variation of the indicators was ＜ 0.20,and the coordination coefficient was 0.25.Conclusions The initial construction of system of self-assessment patient safety by nurses has the advantages of focused expert advice,with scientific results,and is reliable.It can be used for nurses' self-assessment of the security situation in patients.

Objective To explore the distribution and drug resistance of extended-spectrum beta-lactamase (ESBLs)producing Klebsiella pneumoniae in elderly and young and middle-aged patients,and provide reference for rational use of antibiotics for clinicians.Methods Specimens of elderly (≥ 60 years old) and young and middle-aged (18-59 years old) patients who with various clinical infection in Shengjing Hospital of China Medical University from January 2016 to December 2016 were collected as the research object.ESBLs-producing Klebsiella pneumoniae was isolated from 125 patients (60 elderly patients and 65 young and middle-aged patients).The preliminary screening and phenotypic confirmatory test of ESBLs were carried according to the method which was recommended by American Clinical and Laboratory Standards Institute.The drug resistance of ESBLs-producing Klebsiella pneumoniae was analysed and the resuh of the two groups were compared.Results The specimens of ESBLs-producing Klebsiella pneumoniae strains of elderly patients were mainly from urine (36.67％),sputum (33.33％) and whole blood (11.67％);the specimens of young and middle-aged patients were also mainly from urine (24.62％),sputum(24.62％) and whole blood (15.38％).There was statistical significance in the distribution of ESBLs producing Klebsiella pneumoniae in the specimens secretions between the elderly patients and the young and middle-aged patients(P ＜0.05).There was no statistical significance in the distribution of ESBLs producing Klebsiella pneumoniae in the specimens of urine,sputum,whole blood,bile,pus,drain,cerebrospinal fluid,ascitic fluid and catheter between the elderly patients and the young and middle-aged patients (P ＞ 0.05).ESBLs-producing Klebsiella pneumoniae strains of elderly patients were mainly isolated from department of respiration (20.00％,12/60) and department of urinary surgery (18.33％,11/60);the ESBLs-producing Klebsiella pneumoniae strains of young and middle-aged patients were mainly isolated from department of intensive care (16.92％,11/65) and department of neurosurgery (16.92％,11/65).There was statistical significance in the distribution of ESBLs producing Klebsiella pneumoniae in the department of respiration and obstetrics and gynecology between elderly patients and young and middle-aged patients(P ＜ 0.05);there was no statistical significance in the distribution of ESBLs producing Klebsiella pneumoniae in the department of urinary surgery,general surgery,intensive care,neurosurgery,rheumatoid immunology,invasive technology,oncology,digestion,infection,kidney,orthopaedics,rehabilitation,hematology,neurology and other department between elderly patients and young and middle-aged patients(P ＞ 0.05).The drug resistance rates of ESBLs-producing Klebsiella pneumoniae to beta-lactam antibiotic in elderly and young and middle-aged patients were more than 90.00％;the drug resistance rates of ESBLs-producing Klebsiella pneumoniae to carbapenems were nearly 0.00％ in elderly and young and middle-aged patients.There was significant difference in the drug resistance rates of ESBLs-producing Klebsiella pneumoniae to ceftazidime and gentamicin between elderly patients and young and middle-aged patients(P ＜ 0.05);there was no significant difference in the drug resistance rate of ESBLs-producing Klebsiella pneumoniae to another antibiotic between elderly patients and young and middle-aged patients (P ＞ 0.05).Conclusion Both elderly and the young and middle-aged patients can be infected with ESBLs-producing Klebsiella pneumoniae.There was no significant difference in the distribution of ESBLs-producing Klebsiella pneumoniae in most clinical departments (except respiratory and obstetrics and gynecology).The most effective antimicrobial drugs at present for the treatment of ESBLs-producing Klebsiella pneumoniae was carbapenems.There is no significant difference in the drug resistance rates of ESBLs-producing Klebsiella pneumoniae to common antibiotics between elderly patients and young and middle-aged patients.Clinicians should rationally use antibiotics according to the results of susceptibility tests.

Health is an essential element to promote social progress and economic development. It is also a symbol of citizen's peaceful work and life with happy and long life, as well as an emblem of national prosperity and national rejuvenation. Public health develops vigorously in our country. Policy Outlines has been successively issued in China, such as Healthy China 2030 and The Thirteenth Five- year Plan Outline of National Economic and Social Development. Under the Healthy China background, as an important guarantee for public health, nursing higher education in China has experienced a long process of development an reform. It meets the change of the era from education scale, teaching philosophy, establishment of specialized direction and teaching model.

Objective:To seek any differential effect of combining repeated transcranial magnetic stimulation (rTMS) with a modified version of constraint-induced movement therapy (mCIMT) on the walking ability of stroke survivors.Methods:Seventy-five stroke survivors were randomly divided into a sham rTMS group, an rTMS group and a combined group, each of 25. In addition to 40 minutes of routine rehabilitation daily, including balance training, transfer training, muscle strength training, and proprioceptive training five times a week for 4 weeks, the sham rTMS group and rTMS group received sham or genuine rTMS. The combined group received 20 minutes of rTMS followed by mCIMT training 30 minutes later. The treatment was performed once a day, 5 days a week for 4 weeks. Before and after the treatment, all groups were evaluated using the Fugl-Meyer lower extremity assessment, the Berg balance scale, a 10-metre walk test and the modified Barthel index.Results:Significant improvement was observed in the average scores of all three groups in all of the assessments. The combined group′s averages were, however, significantly better than those of the other two groups.Conclusion:Supplementing mCIMT with rTMS can better improve the walking and other abilities in the activities of daily living of stroke survivors.

High cholesterol is one of the important factors inducing cardiovascular and cerebrovascular diseases. Drug therapy is the main method for reducing cholesterol, but has the disadvantages such as high cost and side effects. Studies have shown that intestinal bacteria play important roles in cholesterol metabolism. However, there are few reports on the screening and functional evaluation of cholesterol-lowering intestinal bacteria. In this study, 36 bile-tolerant bacteria were screened from healthy people stool through culturomics using bovine bile acid or artificial mixed bile acids as substrates. Taking Lactobacillus rhamnosus GG (LGG) as a positive control, three bile acid concentration groups (0 g/L, 0.3 g/L, 3 g/L) were set up to evaluate the cholesterol-lowering ability of bile-tolerant bacteria in vitro. Ten bacteria (including Proteus mirabilis, Providencia stuartii, Proteus vulgaris et al) were identified as the dominant cholesterol-lowering bacteria. Six of the above bacteria, Proteus mirabilis, Providencia stuartii, Proteus vulgaris, Proteus penneri, Wohlfahrtiimonas chitiniclastica, Providencia rettger, were evaluated for their ability to reduce triglycerides in vitro and tolerance to artificial gastric juice. Comparing with strain LGG, the six bacteria showed better triglyceride-lowering ability in vitro. With the decrease of pH value of artificial gastric juice and the increase of treatment time, the survival rate of six bacteria decreased. The above screening experiments and functional evaluation provide a basis for further development of potential cholesterol-lowering bacterial products.
