Objective To investigate correlations between nursing students’discrimination on psychopaths and exposure to them.Method One hundred and twenty-one nursing students were involved in the investigation by a general information questionnaire,a discrimination against mental patients scale(DAMPS)and an exposure to mental patients scale(FLS).Results The total mean score on discrimination,scores on isolation dimension and scores on capability were all significantly lower than the norms(all P<0.01).Negative correlation was observed between nursing students’discrimination against patients and exposure to patients(r=-0.31,P<0.05). Conclusion Measures should be taken to encourage nurses to understand patients so as to alleviate their discrimination.

Objective:To investigate the effects of corticotomy assisted orthodontic treatment for mild skeletal Class Ⅱ malocclusion. Methods:7 adult patients with mild skeletal Class Ⅱ division 1 malocclusion were included and underwent corticotomy assisted ortho-dontic treatments.3D measurements and analysis of CBCT data before and after treatment were conducted.Results:The average dura-tion of upper anterior teeth retraction was 3.2 months.After treatment,obvious retraction of up incisiors with the retraction of maxillary alveolar bone and the upper lip backward and downward movement were observed.Conclusion:Corticotomy assisted orthodontic treat-ment is effective in the treatment of mild skeletal Class Ⅱ malocclusion by the retraction of uper anterior teeth,alveolarar bone and soft-tissue profile improvement.

Objective To investigate the influence of stigma on QOL of patients with mental disorders.Methods By using Link stigma series scale and schizophrenic quality of life scale,we assessed and analyzed 406 psychiatric patients′stigma and QOL, as well as the correlation and influence between them.Results The score of perceived devaluation-discrimination dimension of the stigma scale had positive correlation with total score of QOL,score of psycho-social dimension and score of motivation and energy dimension (P <0.05).The scores of challenge dimension and separation dimension in the stigma scale had positive correlation with motivation and energy dimension of the QOL scale (P <0.05).Regression analysis showed that stigma did not have influence on QOL of patients with mental disorders.Conclusion Stigma in psychiatric patients has no significant influence on QOL,but correla-tion relationship exists between them.The higher score of perceived devaluation-discrimination dimension,challenge dimension and separation dimension of stigma scale,the poor QOL the patient would have.

Objeetive To investigate the effectiveness and safety of agomelatine for the treatment of elderly patients with post-stroke depression.Methods A total 80 elderly patients with post-stroke depression were randomly divided into either an agomelatine group or a sertraline group.The Hamilton Depression Scale (HAMD),National Institutes of Health Stroke Scale (NIHSS) and Barthel Index were used to evaluate the patients before and after 1,2,4,and 6 weeks,respectively.Results HAMD,NIHSS,and Barthel index scores were improved significantly after treatment in the agomelatine group (n =38) and the sertraline group (n =42).There were significant improvement in the scores of HAMD,NIHSS and Barthel Index with time in both groups (all P ＜0.001).There were no significant difference in the scores of HAMD and NIHSS at different time points after treatment between the agomelatine group and the sertraline group,and the Barthel Index scores began to have significance difference from the fourth week after treatment (all P ＜ 0.05).Conclusions The efficacy of agomelatine for the treatment of PSD is almost the same as sertraline,and the effect of improving activities of daily living is better than sertraline.The safety of both agomelatine and sertraline is good.

Objective To investigate the factors related to the occurrence of in-stent restenosis (ISR) after percutaneous coronary drug-eluting stent (DES) implantation. Methods A total of 258 consecutive patients with coronary angiography confirmed ISR that occurred at least one year after coronary sirolimus-eluting stent implantation, who were encountered at the Affiliated Ruijin Hospital of Shanghai Jiaotong University during the period from September 2010 to September 2014 , were collected as ISR group; and other 260 age-and sex-matched patients with no ISR at least one year after coronary sirolimus-eluting stent implantation, who were encountered at the same hospital and during the same period, were collected as the control group. The clinical characteristics, biochemical measurements, postoperative medications, left ventricular ejection fraction (LVEF), and coronary interventional features were determined;using multivariate logistic regression analysis the independent factors related to the occurrence of ISR were evaluated. Results Compared to the control group, in ISR group the history of previous myocardial infarction , presence of diabetes mellitus and cigarette smokers were more often seen; serum levels of high-sensitivity C-reactive protein(hs-CRP), glycosylated hemoglobin, low-density lipoprotein cholesterol (LDL-C)and apoliprotein B in ISR group were significantly increased (P<0.05), while LVEF was decreased (P<0.05). Although the number of coronary lesions and the site of stent implantation were quite similar in both groups , the stents used in ISR group were smaller and longer (P<0.05), and bifurcation stenting procedure was more employed in ISR group (P<0.05). Multivariate Logistic regression analysis revealed that the history of previous myocardial infarction, diabetes, cigarette smoking, elevated serum hs-CRP and LDL-C levels, and longer stent length were independent risk factors for the occurrence of ISR, whereas stent diameter and LVEF bore a negative correlation with ISR. Conclusion The occurrence of ISR after coronary sirolimus-eluting stent implantation is related to multiple clinical and coronary angiographic and interventional factors. Effective control of risk factors of coronary heart disease and improvement of left ventricular function play an important role in preventing ISR, especially for the patients who has small vessel disease, and in whom longer stents are employed and bifurcation stenting procedure is carried out.

ObjectiveTo explore the effect of the calcium phosphate cement (CPC) /calcium polyphosphate fiber (CPPF) composites mixed with different proportion of minimal morselized bone on repair of bone defect in vivo. MethodsA total of 36 New Zealand white rabbits were completely randomly designed into A, B, C, D groups and their bilateral radial bone defect model was prepared. The minimal morselized bone (300-500 μm in diameter) was made from the iliac of those rats. The CPPF and CPC were evenly mixed into CPC/CPPF composites which were divided into four groups in accordance with the CPPF weight O, 10％, 30％ and 50％ in CPC/CPPF composite. The CPC/CPPF composites of the four groups was mixed with the minimal morselized bone with ratio of 6:4 and then the mixture was implanted the bone defect of the rabbits in four groups. The gross, X-ray and histological observations were done at four and eight weeks. The biomechanical test was performed at eight weeks. Results When CPPF occupies 30％ of the CPC/CPPF composite, the maximum compressive load and bending loads were better than those in the other groups ( P ＜ 0.05 ), when the histological observation showed the most tight link between the artificial composite and the bone interface and the closest similarity between material degradation rate and the ossification rate, with the best osteogenesis and the optimal ratio.ConclusionThe repair of bone defect can attain the optimal outcome through adding a certain ratio of minimal morselized bone into the CPC/CPPF to adjust the degradation rate of composites.

Objective:To evaluate the effect of high-flow nasal cannula (HFNC) therapy on patients with moderate acute respiratory failure.Methods:This was a randomized controlled trial. The patients with moderate acute respiratory failure in the Intensive Care Unit (ICU) of Changshu Hospital Affiliated to Soochow University from March 2019 to September 2020 were included. Patients with severe asthma or acute exacerbation of chronic respiratory failure, hemodynamic instability, disturbance of consciousness, non-invasive ventilation (NIV) contraindication, urgent need for endotracheal intubation, refusal of intubation, age <18 years and pregnancy were excluded. The patients were randomized to HFNC or NIV. Treatment failure was defined as the need for intubation and invasive ventilation. The vital signs, ROX index, blood gas analysis index, ultrasound parameters and endotracheal intubation rate were recorded at 1, 6, 12, 24 and 48 h after treatment. Kaplan-Meier method was used to draw the survival curve, and multivariate logistic regression was used to analyze the risk factors of treatment failure.Results:A total of 91 patients were included in the study, including 46 patients in the HFNC group and 45 patients in the NIV group. PaO 2/FiO 2 of the two groups were significantly increased after treatment compared with baseline ( P<0.05). The respiratory rate was lower in the NIV group than in the HFNC group at 1 and 24 h ( P<0.05). There were no significant differences in other vital signs, arterial blood gas and ultrasound parameters between the two groups (all P>0.05). The intubation rate was 52.2% in the HFNC group and 48.9% in the NIV group. Kaplan-Meier survival analysis showed that there was no significant difference in intubation rate and mortality between the two groups ( P>0.05). Multivariate logistic regression analysis showed that increased end-diastolic right ventricle/left ventricle ratio ( OR=1.044, 95% CI: 1.012~1.077) and high acute physiology and chronic health evaluationⅡ score ( OR=1.082, 95% CI: 1.006~1.163) at 0 h, lung ultrasound score ( OR=1.353, 95% CI: 1.034~1.772) and end-diastolic RV/LV ratio ( OR=1.097, 95% CI: 1.038~1.159) at 1 h were independent risk factors for non-invasive respiratory strategies failure. Increased diaphragm excursion ( OR=0.341, 95% CI: 0.165~0.704) at 0 h, high PaO 2/FiO 2 ( OR=0.929, 95% CI: 0.884~0.977), increased ROX index ( OR=0.524, 95% CI: 0.332~0.826), and increased diaphragm mobility ( OR=0.119, 95% CI: 0.030~0.476) at 1 h were independent protective factor for successful treatment. Conclusions:HFNC and NIV can improve oxygenation in patients with acute hypoxemic respiratory failure. There is no significant difference in intubation rate and mortality between HFNC and NIV. Ultrasound parameters may be helpful for predicting treatment failure.
