Objeetive To investigate the relationship among social avoidance and acceptance of disability in burn patients.Methods Totally 127 patients were investigated using Social Avoidance and Distress Scale (SADS),Acceptance of Disability Scale (AODS),demographic information questionnaire and disease related information sheet.Results The points of burn patients' SADS was (21.38±6.75),One-way ANOVA showed that gender,marital status,special parts burns,amputation affected social avoidance significantly.The total score and factors scores of acceptance of disability were all negatively related to the score of social avoidance.Regression analysis showed that acceptance of disability,head burns,gender were the independent risk factors of depression.Conclusions Acceptance of disability were negatively related to social avoidance; Nurse can help them accept the reality of disability,develop the confidence to partici-pate in social communication,and improve the social adaptability.

Objective:To investigate the current status of professional identity among the clinical medical postgraduates and its correlation with mentoring function and professional competency, so as to provide reference for optimizing the training mode of clinical medicine postgraduates.Methods:A questionnaire survey was conducted among 217 academic and professional full-time postgraduates from Batch 2016 to 2018 majoring in clinical medicine in Peking University Health Science Center in 2019. The contents included four aspects: basic information, preliminary questionnaire of professional identity, mentoring function scale and professional competency. SPSS 26.0 was used for t test, one-way ANOVA, Kruskal-Wallis H test, and Pearson correlation analysis to analyze the status of professional identity and its correlation with professional competency and mentoring function. Results:Both professional and academic clinical medicine postgraduates had high scores of the overall level and four factors, and there was no statistical significance in the scores between the two groups ( P >0.05). There were significant differences in the overall level, behavior and appropriateness of professional identity among different grades of professional postgraduates ( P<0.05). Correlation study showed that the professional identity was significantly positively correlated with the total score of professional competency and mentoring function ( P<0.001). Further interview survey showed that the role of supervisor and employment prospects also played an important role in the elevation of professional identity. Conclusion:The overall degree of professional identity of academic and professional postgraduates is good and closely related to professional competency and mentoring function and for professional postgraduates, the overall level of professional identity of senior students is better. It is suggested that besides focusing on their professional competency, it is necessary to further optimize the employment policy of academic postgraduates and the training of tutors for professional postgraduates.

OBJECT IVE To provide scientific evidence for the quality standard research of Qingyi mixture （QM）qualitatively and quantitatively. METHODS The high performance liquid chromatography （HPLC）fingerprint of QM was established ，and the chemical pattern recognition analysis was carried out. At the same time ，the contents of 8 components such as chlorogenic acid in the preparation were determined. The determination was performed on Agilent SB-C 18 column with 0.1％ phosphoric acid-acetonitrile as mobile phase （gradient elution ）at the flow rate of 0.6 mL/min. The column temperature was 35 ℃，and detection wavelength was set at 254 nm. Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine（2012 edition），SPSS 20.0 and SIMCA 14.1 were used to perform similarity evaluation ，cluster analysis （CA），principle component analysis （PCA）and orthogonal partial least squares-discriminant analysis （OPLS-DA）of QM samples. RESULTS A total of 22 common peaks were calibrated by 15 batches of QM ，and the similarity was over 0.975. Twenty-two common peaks were assigned and 8 of them were identified. CA ，PCA and OPLS-DA divided the 15 batches of QM into two categories. Meanwhile，5 differential components were screened out ，i.e. peak 9（cichoric acid ），peak 14（baicalin），peak 18，peak 19 and peak 21 （baicalein）. The contents of 8 components，such as chlorogenic acid ，ferulic acid ，cichoric acid ，hesperidin， baicalin，salvianolic acid B ，baicalein and paeonol ，were 0.077-0.094，0.165-0.190，0.100-0.114，0.083-0.107，0.556-0.615，0.288-0.314，0.152-0.188 and 0.114-0.128 mg/g，respectively. CONCLUSIONS The established HPLC fingerprint and content determination method can provide reference for the quality standard research of QM.
