OBJECTIVE To investigate the hand hygiene situation of medical staff in order to carry out supervising and monitoring on their hand hygiene pertinently.METHODS The hand hygiene monitoring data from Jan 2004 to Dec 2007 were retrospectively analyzed.RESULTS The total qualified rate of medical staff hand hygiene was 91.4%;the qualified rate of hand hygiene monitoring for doctors was 89.8%,and it was 96.7% for nurses;the qualified rate of medical staff working in the type-Ⅱenvironment was 93.6%,and the qualified rate of those working in the type-Ⅲ environment was 95.2%;for medical students and refresher doctors,it was 81.0 %.CONCLUSIONS The medical staff still lack the knowledge on hands' cleanliness and disinfection.The supervisors should strengthen monitoring on hand hygiene;some new regulations should be established and practiced,and the hand washing equipments should be updated;the medical staff's compliance of hand hygiene should be improved,and their conceptions of hand hygiene should be strengthened;all-sided originalities on hand hygiene should be carried out in order to reduce the occurring of hospital infections.

Engenfaces is a simple and effective face recognition method based on the relativity of the training set and testing set of face images.However,the correct recognition rate decreases by eigenfaces sharply when the face pose varies.Aiming at improving correct recognition rate in this case,a face recognition approach correlative with face poses is presented.The basic idea is toensure that testing face with particular pose should be matched in the face database whose poses are the same as that of the testing face.Experimental results show the new method gains higher correct recognition rates than traditional eigenfaces method.

Objective To investigate the effects of intervention of information literacy education on the feeling of uncertainty of patients with percutaneous coronary intervention.Methods A total of 228 cases of patients with percutaneous coronary intervention who were hospitalized during July 2010 to June 2012 were selected.The patients were divided into two groups by means of random numbers table:the experimental group (including 119 cases) and the control group (including 109 cases).The patients of the control group received traditional nursing intervention,while the patients of the experimental group received additional information literacy education intervention besides the traditional nursing.The change of feeling of uncertainty and state anxiety level of patients under two kinds of nursing interventions was analyzed and compared.Results The patients of the experimental group had high uncertainty level on the day of admission,(99.17-4.46) points.It was obviously higher than the total score (80) by 50％.Compared with that on the day of admission,the uncertainty level on the night before surgery and on the day of patient discharge significantly declined.The state anxiety level of the patients of the experimental group was (52.97±5.91) points,higher than the normative level of Chinese normal people.Compared with that on the day of admission,the state anxiety level on the night before surgery and on the day of patient discharge significantly declined,and it was lower than the normative level.Compared with those of the control group,the MUIS and SAI assessment of the experimental group on the night before surgery and the day of patient discharge obviously declined.Conclusions The information literacy education intervention was able to reduce the uncertainty level and state anxiety level of patients with percutaneous coronary intervention.Therefore,the nursing quality of patients was enhanced.

ObjectiveTo inyestigate the effect of miRNA-155 expression on the differentiations and functions of CD4 + T lymphocyte in patients with unstable angina pectoris. MethodsTwenty-one patients with unstable angina pectoris (UAP) were enrolled in this study, and another 18 patients with normal coronary arteries evidenced by angiography were assigned as control group. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression of miRNA-155 in CD4 + T lymphocyte of the peripheral blood. And the levels of IFN-γ and IL-4 in serum were determined by using enzyme-linked immunosorbent assay (ELISA). The CD4 + T lymphocyte were isolated from mononuclear cells prepared with Ficoll-Hypaque density-gradients centrifugation from human peripheral blood by magnetic cell sorting system. Then, the CD4 +T cells (2 × 106 cells/mL) were seeded in culture plates with 6 wells.The CD4 + T lymphocytes were divided into 3 groups in experiment: control group, miRNA-155 group, and miRNA-155 inhibitor group. The numbers of Th1 and Th2 cells were measured by flow cytometry analysis (FACS).The protein levels and expressions of IFN-γRα, T-bet, GATA-3 mRNA were measured by using western blotting and qRT-PCR, respectively. The levels of IFN-γ and IL-4 in culture supernatants of CD4 +T lymphocytes were detected by using ELISA. ResultsIn comparison with the control group, there was significant increase in the expression of miRNA-155 and serum level of IFN-γ in the UAP group (P ＜0. 01 ). There was a positive correlation between miRNA-155 and serum IFN-γ ( r =0. 842, P ＜ 0. 0l ).However, in vitro, the number of Th1, the protein level and expression of T-bet mRNA, and supernatant IFN-γ increased, and the protein level and expression of IFN-γRα protein decreased in miRNA-155 group in comparison with the control group (all P ＜0. 01 ). Interestingly, there were no significant differences in the number of Th2 cells, the expressions of GATA-3mRNA and IFN-γRα mRNA, GATA-3 protein and supernatant IL-4 between control group and miRNA-155 group ( all P ＞ 0. 05 ). And the miRNA-155 inhibitor could attenuate the effect of miRNA-155 effectively. ConclusionsThe miRNA-155 can promote differentiations and improve the function of Thl, playing an important role in the pathogenesis of unstable angina pectoris.
