OBJECTIVE To investigate the carotid artery invasion in patients with head and neck malignant tumor with multislice helical CT and MPR. METHODS Thirty-six tumors adjacent to the carotid artery in head and neck were studied using 16 slice helical CT scanner.The following two parameters were measured:tumor-artery angle(the angle surrounded by the tumor)and tumor-artery ratio(the ratio between the length of intersection of the tumor with carotid and the diameter of the carotid).RESULTS Tumor-artery angle:in judgment of carotid involvement with axial CT,the accuracy of the tumor-artery angle≥90?group and the tumor-artery angle≥180?group were higher than that of the tumor-artery angle≥45?group (P

Objective:To understand the current status of patient safety culture (PSC) of nurses in psychiatric department in China and to provide references for nursing managers to formulate effective nursing measures to improve the quality of psychiatric nursing services.Methods:Using the convenient sampling method, a total of 2 624 nurses in psychiatric department from 7 regions of China were selected as the research objects in September 2019. The Self-designed General Information Questionnaire and Hospital Survey on Patient Safety Culture (HSOPSC) were used for the survey. Multiple linear regression analysis was performed on the influencing factors of "adverse event reporting frequency" and "general perception of patient safety" of nurses in psychiatric department.Results:A total of 2 624 questionnaires were returned. The positive response rate of all dimensions of HSOPSC was from 43.33% to 83.31%. The results of multiple linear regression analysis showed that personnel allocation, non-punitive response to errors, feedback and communication to errors, shift and department transfer were the influencing factors of adverse event reporting frequency ( P<0.05) , together explaining 15.8% of the total variation. Personnel allocation, organizational learning and continuous improvement, non-punitive responses to errors, managers' expectations and actions to promote safety, feedback and communication on errors, management support for patient safety and shifts and department transfers were influencing factors for patient safety culture ( P<0.05) , together explaining 41.2% of the total variation. Conclusions:The cognitive level of psychiatric nurses on PSC needs to be improved. It is recommended that nursing managers intervene in three areas of personnel allocation of psychiatric nurses, non-punitive reactions to errors and frequency of adverse event reports, so as to improve psychiatric nurses' recognition of PSC, thereby improving the quality of psychiatric nursing services.

Objective:This study aims to investigate Mental health nurses′ perceptions of patient safety culture in different levels of hospitals, so as to provide the basis for understanding the perceptions of patients' safety culture among psychiatric nurses in different levels of hospitals.Methods:The self-designed general data questionnaire and the Hospital Patient Safety Culture Questionnaire were used to collect and analyze the data of 2 624 psychiatric nurses from level 3, level 2 and Level 1 hospitals in the seven administrative regions of China.Results:The scores of nurses in primary and secondary hospitals were 132.74±1.35 and 151.99±1.74, lower than 154.76±1.85 in tertiary hospitals ( χ2 value was 19.228, P < 0.01). There were statistically significant differences in the non-punitive response to error, feedback and communications about error, communication openness, hospital management support for patient safety, and frequency of events reported, overall perception of patient safety among psychiatric nurses at different levels of hospitals ( χ2 value was 7.997-37.681, P<0.05). Conclusions:The mental health nurses′ perceptions of patient safety culture in different levels of hospitals need to be improved, and hospital managers at all levels should focus on the non-punitive response to errors and personnel allocation. In addition, managers of primary and secondary hospitals also need to strengthen the training of nurses in such dimensions as feedback and communication of errors, openness of communication, management support for patient safety, frequency of adverse event reports, and overall sense of patient safety.

ObjectiveTo investigate the effect of Qianggan capsules on liver fibrosis score and insulin resistance index in patients with nonalcoholic fatty liver disease (NAFLD). MethodsA total of 85 NAFLD patients who were treated in the Eighth People′s Hospital of Shanghai from August 2014 to July 2015 were enrolled and randomly divided into treatment group (45 patients) and control group (40 patients). The patients in the treatment group were given Qianggan capsules, and those in the control group were given polyene phosphatidylcholine capsules. The course of treatment was 24 weeks for both groups. The changes in serum aminotransferases ［aspartate aminotransferase (AST) and alanine aminotransferase (ALT)］, homeostasis model assessment of insulin resistance (HOMA-IR), and NAFLD fibrosis score (NAFLDFS) after treatment were observed in both groups. The t-test was used for comparison of continuous data between groups, before-after comparison within each group was made by paired t-test; and the chi-square test was used for comparison of categorical data between groups. ResultsBoth groups showed significant improvements in ALT and AST levels after treatment (all P＜001). After treatment the treatment group showed significant reductions in HOMA-IR and NAFLDFS (358±085 vs 248±078，t=640，P＜001; -178±124 vs -235±098,t=240,P＜001) and the treatment group had significantly lower HOMA-IR and NAFLDFS than the control group(1248±078 vs 309±089,t=336,P＜001;-235±098 vs -148±108,t=380,P＜001). No serious adverse events were observed during the course of treatment. ConclusionQianggan capsules not only reduce the levels of serum aminotransferases, but also improve insulin resistance and reduce fibrosis degree in NAFLD patients.

Objective:To understand the cognition and attitude of nursing managers to horizontal violence among nurses.Methods:From October to December 2018, semi-structured interviews were conducted with nursing managers in a Class ⅢGrade A hospital in Shanghai by using the purposive sampling method.Results:Five themes were extracted, namely, the low level of understanding of nurse managers on horizontal violence among nurses, effects of horizontal violence among nurses on psychology and work of nurses, the lack of enthusiasm of nursing managers in dealing with horizontal violence among nurses, nursing managers thoughthorizontalviolence was influenced by many factors and nursing managers thought that there was a lack of support for nurses suffering from horizontal violence.Conclusions:Nursing managers should enrich relevant knowledge, timely find and deal with horizontal violence in time and provide psychological support to victim nurses. Medical institutions should also formulate relevant rules and regulations to provide a basis for nursing managers when dealing with horizontal violence.

Objective To examine the benefits of ECMO for potential organ donors with hemodynamic instability after brain death.Methods Three brain-dead potential donors who presented with hemodynamic instability despite maximal medical management,finished a declaration of brain death,that were supported by extracorporeal circulation membrane oxygenation (ECMO).Results Donor organs,including six kidneys,and two livers,were harvested from the three donors under ECMO support,leading to 8 successful transplantations.The organs functioned well and the recipients made full recoveries.Conclusion Our experience indicates that ECMO allows for the maintenance of abdominal organ tissue perfusion without warm ischemia before organ procurement,providing sufficient time for safe organ donation procedures and reducing the risk of unpredictable cardiac arrest that could result in the donor death and graft loss.

Objective:To analyze the relationship between self-disclosure, self-efficacy and medical coping modes in adolescent depression, and explore the mediating effect of self-efficacy between self-disclosure and medical coping modes.Methods:Using the convenience sampling method, a total of 403 adolescents with depression in a tertiary psychiatric hospital in Beijing were recruited from March 2020 to March 2021. The data of general information questionnaire, distress disclosure index scale, medical coping modes questionnaire and general self-efficacy scale were collected.SPSS 26.0 software was used to analyze the correlation between self-disclosure, self-efficacy and medical coping modes of adolescent patients with depression, and Stata 13.1 software was used to analyze the mediating effect of self-efficacy between self-disclosure and medical coping modes.Results:The scores of dimension of the medical coping modes of adolescent depression patients were(16.90±3.84) for facing, (16.34±2.88) for yielding, (12.48±4.31) for avoiding, (30.47±9.91) for self-disclosure and (19.63±6.54) for self-efficacy, respectively. Self-disclosure and self-efficacy were positively correlated with facing of medical coping modes ( r=0.301, 0.327, both P<0.01), and negatively correlated with yielding of medical coping modes ( r=-0.465, -0.487, both P<0.01). Self-disclosure was negatively correlated with avoidance of medical coping modes ( r=-0.118, P=0.018). The direct effect of self-efficacy on medical coping modes was 0.103, and the total effect was 0.365, and the mediating effect accounted for 28.22%. Conclusion:Self-efficacy partially mediates between self-disclosure and medical coping modes in adolescents with depression.
