Objective To explore the characteristics of firefighters in post-traumatic stress disorder（PTSD） and vicarious trauma（VT） as rescuers who experience traumatic situations. Methods From November 2020 to February 2021,using the convenience sampling,a survey was conducted on 2 084 firefighters in Shanghai by the self-compiled general demographic data questionnaire,stress perception scale and rescuer substitute trauma questionnaire,and the results of the survey were analyzed by one-way analysis of variance,correlation analysis and Johnson Neyman method. Results The average score of the PCL-5 scale for fire rescue personnel was （27.54±9.16）points,and the average score of the VT questionnaire was （65.17±26.00）points. The stress perception score[（21.77±7.93）points] offront-line firefighters was significantly higher than that of non-front-line fire rescue workers[（19.38±8.16）points]（P<0.01）. The total score ofstress perception of 1 806 front-line firefighters was significantly positively correlated with the total score of PCL-5 scale and the symptoms of the four groups（all P<0.01）. The moderating effect test found that traumatic memory played a moderating role between stress and PTSD symptoms,and stress feelings would lead to higher PTSD symptoms in the context of traumatic memory. Conclusion The symptoms of post-traumatic stress disorder and the vicarious trauma among firefighters in each detachment in Shanghai are more obvious,the management and fire rescue personnel should increase their awareness of their own psychological trauma and stress when participating in rescue work,and pay more attention to mental health.

Objective To establish a method for simultaneous determination of acrylamide andL-asparagine in Atractylodis macrocephalae rhizome（AMR）,analyze the content change of acrylamide and L-asparagine during the thermal processing of AMR,so as to providebasis for the research of processing technology. Methods The simultaneous determination of L-asparagine and acrylamide in AMR was realized by dispersed solid phase extraction using multi-walled carbon nanotubes（MWCNTs） and liquid chromatography tandem mass spectrometry（LC-MS/MS）.Using this method,the contents of L-asparagine andacrylamide in processed AMR samples were determined under different processing temperature and time. The risk of acrylamide contamination in AMR was evaluated by margin of exposure（MOE）. Results In the validation of the optimized method,the recoveries of L-asparagine were 98.4%-103.2% with relative standard deviation（RSD） of 2.5%-3.6%. The recoveries of acrylamide were 97.5%-101.9% with RSD of 1.9%-3.1%. The linear relationships of acrylamide and L-asparagine were good within the range of 1-50 ng/mL and 25-1000 ng/mL respectively,and the correlation coefficients were ≥0.99. The detection limit of acrylamide and L-asparagine was 0.003 mg/kg and 0.1 mg/kg respectively. During the processing of AMR,L-asparagine showed a downward trend with the increase of time,and the content of acrylamide first increased and then decreased with the processing time. According to the change of acrylamide content in AMR after processing,the lowest value was 79.3 μg/kg and the highest value was 1558.9 μg/kg,which led to the lowest MOE value of 673.6,indicating safety risk. Conclusions The study establishes and verifies a method for the simultaneous determination of acrylamide and L-asparagine. After the thermal processing of AMR,the concentration of acrylamide increases significantly,resulting in potential safety risks. Comprehensive consideration was needed to further improve and standardize the processing technology.

Objective To understand the public's awareness of cardiopulmonary resuscitation,the current training situation and the factors influencing the public's willingness to participate in the training,provide a basis for developing training programs that meet the public's wishes. Methods From May 4th to June 30th,2019,a self-designed questionnaire was used to conduct an online survey among the public who met the inclusion criteria. Results A total of 1 588 valid copies were recovered in this survey. The qualification rate of CPR related knowledge among the public was 45.53%,49.69% of the public havereceived the CPR training,and 91.50% of the public were more willing to participate in CPR training. The logistic regression analysis showed that people aged 45-<60 years old were less willing to participate in training,and women,qualified CPR knowledge,willingness to implement CPR for others,and higher frequency of training were the protective factors for their willingness to participate in training （all P<0.05）. The main obstacle to public participated in training was"I don't know where there is training"（67.41%）. Conclusion The public's awareness of cardiopulmonary resuscitation in China is at a medium-low level,although the public's willingness to participate in the training is high,the actual participation rate is not high,which needs to be continuously improved according to the actual situation of the public in the future training.

Objective To explore the status of work connectivity behavior,psychological detachment,perceived work-family boundary control,and work-related quality of life among nurses in grade-A tertiary hospitals of Shenzhen City,explore the impact of work connectivity behavior on quality of work and life of nurses,as well as the multiple mediating effects of psychological detachment and work-family boundary control. Methods From June to September 2020,378 clinical nursesfrom threegrade-A tertiary hospitals of Shenzhen City were investigated by the general situation survey,work communication tool use scale,psychological detachment scale,sense of boundary control questionnaire,and work related quality of life scale,and the data were analyzed. Results The total scores of work connectivity behavior,psychological detachment,perceived work-family boundary control,and work-related quality of life among nurses in three grade-A tertiary hospitals of Shenzhen City were （11.31±2.88）,（7.51±2.96）,（22.77±4.77） and （108.74±18.10）points,respectively. The work connectivity behavior of nurses was negatively correlated with psychological detachment,work-family boundary control,and work-related quality of life（r=-0.387,-0.313,-0.281,all P<0.01）.The psychological detachment was positively correlated with perceived work-family boundary control,and work-related quality of life（r=0.163,0.360,both P<0.01）. The perceived work-family boundary control was positively correlated with work-related quality of life（r=0.282,P<0.01）. The connectivity behaviornot only had a direct negative predictive effect on work-related quality of life（the direct effect was 0.31,accounting for 40.26% of the total effect）,but also indirectly affected work-related quality of life through psychological detachment andperceived work-family boundary control respectively（indirect effects were 0.22 and 0.24,accounting for 28.57% and 31.17% of total effects respectively）. The work connectivity behavior had a negative predictive effect on psychological detachment（β=-0.44,P<0.01）,and psychological detachment had a negative predictive effect on work-related quality of life（β=0.49,P<0.01）. The work connectivity behavior had a negative predictive effect onperceived work-family boundary control（β=-0.39,P<0.01）,and perceived work-family boundary control had a negative predictive effect onwork-related quality of life（β=-0.39,P<0.01）. Conclusions The psychological detachment and perceived work-family boundary control have multiple mediating effects on the impact of work connectivity behavior on the work-related quality of life of nursing staff. It is suggested that the nursing manager should be reminded to appropriately use the frequency of mobile phone use related to off-hours work. Secondly,nursing staff can try to actively participate in leisure activities outside work,so as to obtain physical and mental relaxation,and then devote themselves to work and work life quality in a better state.

：The severe acute respiratory syndrome coronavirus（SARS-CoV-2） is highly contagious,posing a great threat to human life and security. The early and rapid diagnosis of SARS-CoV-2 plays an important role in fighting outbreaks,and there is an urgent need for a rapid,sensitive and inexpensive test system. The surface-enhanced raman scattering（SERS）,as a cutting-edge analytical technique,has the ability of fingerprint recognition,which can provide quantitative results with high specificity,sensitivity and multiple detection,and has broad prospects in the immediate diagnosis of viruses.It has been applied in the detection of various influenza virus subtypes. The lateral flow immunoassay（LFIA） and other point of care（POC） devices provide a fast,efficient and reliable platform.However,LFIA has limitations in quantitative and sensitive analysis of SARS-CoV-2 detection.To solve these problems,we review the combination of SERS technology and LFIA in current status and future challenges of the quantitative analysis of SARS-CoV-2.
