Objective To investigate the post traumatic stress disorder scores of undergraduate and the correlation between emotional approach coping(EAC) in unaffected region after Wenchuan-earthquake.Methods PTSD Check list-Civilian Version (PCL-C) and emotional approach coping scale(EACS) were used to assessed 880 undergraduates in Nanjing. Results (1)The average score of PCL-C was 30.52±9.64, and the prevalence rates of PTSD was found 5.3%.(2)Gender difference were found in social function(male:1.66±0.80,female:1.52±0.63, t =2.664,P =0.005) and positive scores of PTSD(male:31.32±10.81,female:29.81±8.41,t =2.263,P =0.022).(3)No significant difference was found in different specialty between PTSD,but in emotional procession and emotional expression.(4)Emotional-approach coping and expose time in front of media came into the regression equation of PTSD symptoms.Conclusion The score of PCL-C of undergraduate in unaffected region are infected by how long he spend in front of media and how he use emotion-approach coping strategy to cope with this shock bringing by Wenchuan-Earthquake

Objective To examine the reliability and validity of Chinese revision of connor-davidson resilience scale(CD-RISC) in Chinese college students.Methods 1610 college students were tested with CD-RISC.783 of them took a more test by BFI and SCL-90 at the same time.After three weeks,83 students were retested by CD-RISC.Results (1) The results of confirmatory factor analysis (x2/df =6.632,RMSEA =0.059,GFI =0.934,AGFI =0.915,CFI =0.927,NFI =0.915) indicated that the three-factor model reasonably fitted Chinese college students.(2) The Cronabach α coefficients of the CD-RISC and three factors called adaptability,tenacity and autonomy were 0.914,0.865,0.784,0.767 respectively; the mean inter-item correlation coefficients of them were 0.364,0.417,0.425,0.398 respectively; the Guttman split-half coefficients were 0.888,0.843,0.707,0.650 respectively; the retest-reliability coefficients were 0.856,0.742,0.777,0.747.(3) The scores of the total scale of CDRISC and three factors were significantly correlated to BFI and SCL-90(P＜0.01).There were significant differences between the low-resilient group and the high-resilient group in every index of BFI and SCL-90.(4) There were significant differences between male and female students in CD-RISC and factor tenacity and autonomy(male:2.77±0.60,2.70-±0.74,2.65±0.68;female:Z70±0.53,2.62±0.67,2.54±0.62; P＜0.05).Conclusion The Chinese version of CD-RISC is a reliable and valid method for assessing resilience in Chinese college students.

Abstract: To report a case of Aspergillus salwaensis-induced spinal infection and its laboratory detection. The inflammatory granulation and necrotic tissue samples of a patient with spinal infection were collected from, the Affiliated Hospital of Chengde Medical College on June 17, 2020 for direct smear microscopy and culture, and the isolated strain was identified by microscopy by smear staining, matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS), molecular identification and in vitro antifungal susceptibility test. The patient was 62 years old female and presented with recurrent chest and back pain with no obvious cause. The initial diagnosis was spinal infection, after 7 days of treatment with levofloxacin, the effect was not good. Surgery was then performed remove the lesion via posterior thoracic debridement, and fungal hypha was observed under microscope in tissue specimens. The isolated strains had no typical structure, MALDI-TOF-MS was used for identification for many times, but there was no identification result. After 7 days of fluconazole treatment, the patient's condition improved, and her chest and back pain were alleviated compared to before surgery. The patient was discharged and followed up in the outpatient department, the fungus was later identified as Aspergillus salwaensis by sequence analysis of the internal transcribed spacer (ITS) gene sequencing, and the patient's antifungal medication was changed to voriconazole after with the attending physician. The patient consciously recovered well with no pain in the operative area and normal spinal activity at 1 year follow-up. The possibility of spinal fungal infection should be considered in patients with back pain without a clear cause and poor response to routine antibiotic treatment. Direct smear report of microscopic results are very important for guiding clinical antibiotic selection for rare filament fungi with atypical colony and microscopic morphology and unsuccessful MALDI-TOF-MS identification, molecular biological methods such as ITS sequence analysis can be helpful for early identification of the fungal species, improving identification speed.

Through PCA analysis, it was possible to clearly distinguish the medicinal herbs of Pulsatilla chinensis from different areas. Combined with OPLS-DA analysis, it was found that peak 2, peak 3, peak 6 were the main markers of Pulsatilla chinensis from different producing areas. Conclusion:The established method has good specificity, repeatability and durability, and it can effectively distinguish the common counterfeits of Pulsatilla chinensis, and provide the basis of quality control and selection of origin for Pulsatilla chinensis.

Objective:To establish the ultra high performance liquid chromatography (UPLC) fingerprints of Mume flos at different flowering stages; To provide reference for the quality research of Mume flos.Methods:The fingerprints of Mume flos were established by UPLC method, and the common peaks were identified by high performance liquid chromatography high resolution mass spectrometry (LC-MS). Chemometrics analysis was carried out with the fingerprints' common peak area of plum blossom at different flowering stages as a variable. Semiquantitative analysis of changes in flavonoids and phenolic acids in Mume flos at different flowering stages was conduct using peak area calculation method.Results:Totally 31 common peaks were identified in the fingerprints of plum blossom medicinal materials at different flowering stages and 9 components were identified. Clustering analysis (HCA) and principal component analysis (PCA) both classified plum blossom medicinal herbs at different flowering stages into three categories. Among them, there were significant differences between the groups at the bud stage, blooming period, and final flowering period, while the differences between the groups at blooming period and final flowering period were relatively small. The orthogonal partial least squares discriminant analysis (OPLS-DA) screened 16 different components with VIP>1.0. The contents of phenolic acids in different flowering stages were as follows: bud stage>blooming period>final flowering period, while the contents of flavonoids were as follows: blooming period>final flowering period>bud stage.Conclusions:This method is simple and reliable, and can provide reference for the quality evaluation of plum blossom medicinal materials at different flowering stages.
