Objective To explore the level of patient safety culture of nurses, so as to provide more objective information for the developmental measures to improve patient safety culture. Methods 1 866 nurses from six grade-3 hospitals of a province were investigated by patient safety culture assessment scale. Results The total scores of patient safety culture of nurses was 3.57 ± 0.42, belongs to the middle-level. 5 factors in descending order according to the questionnaire scores was teamwork climate, safety climate, job Satisfaction,perception of management and stress recognition. The lower scores were the punishment of adverse events, job stress, work intensity, the staffing and so on. Conclusions It is very important that nurse managers should focus on improving a safer system in nursing, find out the potential risks, create a positive patient safety culture,and reduce or prevent adverse events of nursing in order to promote patient safety.

AlM: To investigate the association between the degree of anterioruveitis and related factors including inflammatory markers as well as sacroiliac joint imaging in patients with ankylosing spondylitis ( AS) .
METHODS: Anterior changes evaluated by slit lamp, erythrocyte sedimentation rate ( ESR ) , C - reactive protein ( CRP ) and magnetic resonance imaging of 55 cases with AS associateduveitis were retrospectively analyzed. A modified endotoxin-induced uveitis ( ElU ) clinical standard was used for uveitis grading. SPARCC sacroiliac scoring was used to evaluate bone edema of sacroiliac joint. The correlation between the degree of uveitis and sacroiliitis was assessed.
RESULTS: ln the 55 patients with AS, ElU grading scored 2-10, and SPARCC index scored 0-22. Further analysis showed that the severity of uveitis was significantly correlated with ESR (r=0. 869, P<0. 001) and CRP (r=0. 485, P<0. 001). The degree of anterior uveitis in AS patients was not correlated with inflammation of sacroiliac joint (r=0. 237, P=0. 081).
CONCLUSlON: Local autoimmunity of uveitis and sacroiliac joint inflammation with subsequent bone formation in AS might be mutually independent processes.

OBJECTIVETo observe the effects of the external application of Qiyu oil gauze (QYOG) for promoting post-operational healing in patients with anal fistula and to explore its mechanism of action so as to provide a beneficial scientific basis for its wide use.

METHODSSixty patients with anal fistula scheduled to receive simple low anal fistulectomy were equally assigned, according to the sequence of hospitalization, to the tested group and the control group, and their wounds were classified according to longitudinal diameter into three grades (Grade I with a diameter below 2 cm; Grade II, 2-5 cm; and Grade III, over 5 cm). After the operation was completed and the operational wound was sterilized with benzalkonium bromide, the wound substratum was packed with QYOG in the test group and with vaseline gauze in the control group. The packing gauze was changed every day till the wound was healed. The healing time of the patients was observed, and the number of capillaries and positive cell percentages of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and epidermal growth factor (EGF) in wound granulation tissues were counted on the 5th day after the operation.

RESULTSThe wound healing time was 17.80+/-5.46 days in the test group, which was significantly shorter than that in the control group (21.90+/-6.32 days, P<0.01). The number of capillaries and positive cell percentages of VEGF and bFGF in wound granulation tissues on the 5th day in the tested group were higher than those in the control group (P<0.01), though the difference in EGF between the two groups was insignificant (P>0.05).

CONCLUSIONQYOG could shorten the wound healing time after anal fistulectomy, which suggests that it participates in the stimulation of wound granulation tissues to produce VEGF and bFGF, and thus promotes capillary genesis and improves blood circulation in wounds so as to promote wound healing.

AIM: To explore whether necroptosis contributes to the high glucose (HG)-induced damage in hu-man umbilical vein endothelial cells (HUVECs).METHODS: The protein levels of receptor-interacting protein 3 (RIP3) and cleaved caspase-3 were detected by Western blot.The intracellular levels of reactive oxygen species (ROS) were deter-mined by DCFH-DA staining followed by photofluorography.Mitochondrial membrane potential (MMP) was measured by rhodamine 123 staining followed by photofluorography.RESULTS: Treatment of HUVECs with HG at different concentra-tions (10, 20 and 40 mmol/L glucose) for 24 h gradually enhanced the expression levels of RIP3.Treatment of HUVECs with HG (40 mmol/L glucose) for different time (3 h, 6 h, 9 h, 12 h and 24 h) also up-regulated the expression levels of RIP3, peaking at 9 h.Pretreatment of HUVECs with 20 μmol/L Z-VAD-FMK (an inhibitor of caspase) for 30 min before exposure to HG enhanced the expression level of RIP3.Pretreatment of HUVECs with 100 μmol/L necrostatin-1 (an inhi-bitor of necroptosis) for 1 h before exposure to HG alleviated the HG-induced injuries, such as a decrease in cell viability, an increase in ROS generation and dissipation of MMP, but up-regulated the protein level of cleaved caspase-3.CON-
CLUSION: Necroptosis mediates HG-induced injury in HUVECs.There is a negative interacting between necroptosis and apoptosis.

Objective To explore and evaluate the effect of family intervention on quality of life of children with tourette syndrome.Methods Total of 200 children with tourette syndrome were randomly divided into observation group and control group.The observation group received conventional treatment and family intervention including family education,family visits and education guidance to build a harmonious family environment and healthy lifestyle,while the control group only received the conventional treatment and care.The therapeutic effects of both groups were assessed by Yale Global Tic Severity Scale (YGTSS),PedsQLTM 4.0 universal core scales score and Children' s subjective quality of life questionnaires.Results One year later,the frequency,intensity,complexity,interference,damage of spasm in the observation group were significantly lower than those of the control group (t =14.370,20.612,17.677,24.386,11.643,13.972,respectively;P ＜0.01 ).The average scores of families report in the observation group in physical function,mental function,social function,role function were (90.78 ± 11.32 ),( 88.80 ± 14.43 ),( 76.78 ± 11.30 ),( 66.80 ± 14.53 ),respectively,which were higher than (80.10 ± 14.23 ),(58.10 ± 13.32),(58.50 ± 14.32),(52.80 ± 13.15 )in the control group,and the differences were statistically significant (t =5.873,17.563,10.677,7.139,respectively;P ＜ 0.01 ). Each dimension score of children self-evaluation in the observation group was significantly higher than that in the control group (P ＜ 0.001 ).There were significant differences in family life,companion contact,life environment,self-cognition,depress experience,anxiety,except the dimension of emotional body( P ＜0.01 ).Conclusions Family intervention can significantly improve the quality of life and the quality of the population for children with tourette syndrome.

Objective To investigate uncertainty in illness state and its influential factors in patients with lung cancer. Methods A total of 280 hospitalized patients with lung cancer were evaluated with the scales of the demographic data and the Mishel's Chinese version of uncertainty in illness. Results Totally 280 qualified questionnaires were obtained, and the rate for response was 93. 3%. The total score of the uncertainty in illness was (105.15?2. 66); There was a significant difference of the score of the uncertainty in illness among different occupation groups, smoking status, self-uncomfortable level of disease groups, self-knowing of suffering from lung cancer groups, different treatment groups, different degree of social support groups, different religious belief groups; Religious beliefs influent the sense of uncertainty in illness in Patients with Lung Cancer. Conclusions There is a high degree of uncertainty in illness in patients with lung cancer; Lung cancer patients with different features have different levels of uncertainty in illness; Religious beliefs influent the sense of uncertainty in illness in Patients with Lung Cancer.

Host genetic factors, such as human leukocyte antigen (HLA) alleles, are important in Human immunod-eficiency virus (HIV) infection and its progression to AIDS. HLA class I genes, especially highly polymorphicHLA-B genes, are involved in the activation of HLA-restricted cytotoxic T lymphocytes (CTLs) against HIV, andthus control susceptibility to or protect against this virus. The present study was aimed to determine the distributionof HLA-B alleles in the Chinese Uygur ethnic group and its association with HIV infection. One hundred ten healthycontrol (HIV negative) and 128 HIV positive Chinese Xinjiang Uygur ethnic individuals were used in this study.HLA typing for B allele was performed by polymerase chain reaction (PCR) with sequence-specific primers (SSP).Hardy-Weinberg equilibrium was calculated using POPGENE software for the healthy control group. The HLA-Bfrequency of each allele was compared between the patients and the controls using the chi-square test. In HIV-1-pos-itive group, gene frequency of allele B * 4901 was significantly higher compared to the healthy control subjects (P=0.02, OR=3.06, 95%CI=1.16～8.10 forB*4901). In contrast, the gene frequency of B * 40 in healthy controlswas significantly higher than in the HIV-positive patients (P=0.02, OR=0.39, 95%CI=0.07～0. 92 for B* 40).In this study, HLA allele B * 4901 may be associated with increased susceptibility to HIV-1 infection, whereas the B* 40 allele may be associated with resistance to H HIV-1 infection.

OBJECTIVETo compare the obstetric and perinatal outcomes between fresh embryo transfer (ET) and frozen-thawed ET (the "freeze-all" strategy) and evaluate the benefits of the "freeze-all" embryo strategy for young patients.

METHODSWe reviewed a total of 2091 ET cycles performed between January, 2011 and December, 2015 in women aged 20-35 years, including 1295 fresh ET cycles and 796 frozen-thawed ET cycles. The demographic characteristics, ovarian stimulation syndrome, clinical pregnancy rates, live birth rate and the obstetric outcomes (gestational age, preterm delivery rate and mean birth weight) were compared between the two groups.

RESULTSThe mean age of the patients receiving frozen-thawed ET cycles had a significantly younger age than those having fresh ET cycles (29.5 vs 30.2 years, P<0.05); the patients undergoing frozen-thawed ET cycles also had significantly higher estradiol level on the day of trigger (12 973 pmol/L vs 8673 pmol/L) and a greater oocyte number retrieved (12.7 vs 8.7). The incidence of severe ovarian hyperstimulation syndrome was significantly lower in patients with frozen ET than those with fresh ET (P<0.05). No significant differences were found in the pregnancy rate (59.5% vs 56.0%; P>0.05), live birth rate (50.3% vs 47.0%; P>0.05), mean birth weight or gestational age between the two groups.

CONCLUSIONSThe freeze-all policy produces similar pregnancy and obstetric outcomes with those of fresh ET. Our results support the hypothesis that the freeze-all strategy help to prevent OHSS with a good pregnancy rate.

OBJECTIVETo analyze the clinical characteristics of plastic bronchitis associated with 2009 influenza A virus (H1N1) infection.

METHODA retrospective investigation of the clinical manifestation, bronchoscopy, and the histology of the cast, clinical course and outcome of 8 children with plastic bronchitis associated with influenza A virus (H1N1) infection during winter of 2009 and 2010 was performed.

RESULTAll 8 cases were boys, the range of age was 3 to 6 years. Five cases occurred in 2009 winter, accounting for 3.3% (5/150) of hospitalized children with influenza A (H1N1) infection; 3 cases occurred in 2010 winter, accounting for 15.8% (3/19) of hospitalized children with influenza A (H1N1) infection. Two patients had an underlying chronic disease, 1 had asthma, and the other had allergic rhinitis and atopic dermatitis. All the 8 cases had fever, cough and sputum; 2 had wheezing; 5 had respiratory distress. All 8 cases were diagnosed as influenza A virus (H1N1) infection complicated with pneumonia, of whom 5 patients had atelectasis, 2 had pneumothorax, 1 had pneumomediastinum, 1 had parapneumonic effusion, 2 patients were suspected of foreign body aspiration. Seven cases were admitted to an ICU, 5 patients developed respiratory failure, and 3 patients required mechanical ventilation. Flexible bronchoscopy and bronchial lavage was performed in all cases and showed bronchial cast. Histological examination of the bronchial cast revealed a fibrinous material containing large quantity of eosinophils, neutrophils, and lymphocytes in 7 patients, fibrinous material and necrotic material without inflammatory cells in 1 patient. After the bronchial cast was removed, all patients were improved greatly, no patients died.

CONCLUSIONPlastic bronchitis is a life-threatening complication associated with 2009 influenza A (H1N1) virus infection in children. In children with rapid and progressive respiratory distress with lung atelectasis or consolidation on chest radiograph, plastic bronchitis should be considered. Bronchoscopic extraction of casts should be carried out early.
