0.05),but the ratio of fPSA/tPSA in PC group was very lower than that in BPH group(P20.0 ?g/L,the sensitivity and the specificity was 91.6%(22/24) and 87.5%(21/24).Conclusion It can improve the differential diagnosis between PC and BPH to use the ratio of fPSA/tPSA combining with the serum tPSA.It is important for the observation of the differential diagnosis and the therapeutic effects of PC and the preparation of the high risk persons and etc.

Objective:To understand the current level of work engagement of new nurses and analyze the relationship between the variables of emotion regulation difficulties, job crafting, and work engagement, to provide a theoretical basis for nursing managers to develop interventions to enhance the level of work engagement of new nurses.Methods:The convenience sampling method was applied to select a total of 637 new nurses from 11 tertiary levels A hospitals in Beijing City, Zhejiang Province, Guangxi Zhuang Autonomous Region, Anhui Province, and Hubei Province from April to June 2022 as the respondents, and the general information questionnaire, Emotion Regulation Difficulties Scale, Job Crafting Scale and Work Engagement Scale were used to conduct a cross-sectional survey. The mediation effect was analyzed by AMOS 26.0 structural equation model.Results:Finally, 626 new nurses were included, and scored (31.08 ± 10.94) points on the Work Engagement Scale, with a mean entry score of (3.45 ± 1.22) points. Work engagement was significantly negatively associated with difficulties in emotion regulation ( r=-0.291, P<0.01) and positively associated with job crafting ( r=0.724, P<0.01). Analysis of mediating effects revealed that job crafting partially mediated the relationship between difficulties in emotion regulation and work engagement ( β=-0.424, P<0.001). Conclusions:New nurses' work engagement was at an intermediate level, and job crafting partially mediated the relationship between emotion regulation difficulties and work engagement. Nursing managers should strengthen training on emotion regulation strategies for new nurses and construct intervention strategies based on job crafting, to improve new nurses′ work engagement.

Objective To compare the image quality of chest low dose CT (LDCT) using automatic exposure control (AEC) and constant current control (CCC) and explore a more reasonable scanning protocol. Methods Two hundred and eighty participants were examined with 64 CT scanner at 7 centers in China. All were divided into 4 groups. Two groups underwent LDCT using AEC with standard deviation set at 25 (A1) and 30 (A2) respectively and the tube current ranged from 10 mA to 80 mA. The other two groups underwent LDCT using CCC with tube current set at 40 mA (C1) and 50 mA (C2) respectively. The axial and MPR images were evaluated by two radiologists who were blinded to the scanning protocols.The radiation dose, noise and the image quality of the 4 groups were compared and analyzed statistically.Differences of radiation dose and noise among groups were determined with variance analysis and t test,image quality with Mann-Whitney test and the consistency of diagnosis with Kappa test. Results There was a significant lower DLP in AEC group than in CCC group [(82.62±40.31)vs ( 110.81±18.21) mGy·cm (F =56. 88 ,P < 0. 01 )], whereas no significant difference was observed between group A2 and group A1 0. 05]. The noisy of AEC group was higher than that of CCC group both on lung window(41.50±9.58 vs 40.86±7.03) and mediastinum window (41.19±7.83 vs 40.92±9.89), but there was no significant difference( Flung =0.835, P=0.476, Fmediastinum =1.910, P=0.128).The quality score of axial image in AEC group was higher than that in CCC group (superior margin of the brachiocephalic vein level: 4.49±0.56 vs4.38±0.64,superior margin of the aortic arch: 4.86±0.23 vs 4.81±0.32,the right superior lobar bronchus Level:4.87±0.27 vs 4. 84 ± 0. 22, the right middle lobar bronchus Level: 4.90±0.25 vs 4.88±0.21) except on the right inferior pulmonary vein level(4. 92 ±0. 25 vs 4. 93 ±0. 17) and superior margin of the left diaphragmatic dome level (4. 91±0.27 vs 4.93±0.22) on lung window, but no significant differences (F=0.076-1.748, P>0.05) were observed. A significant higher score in AEC group was observed on mediastinum window compared with CCC group on superior margin of brachiocephalic vein level (2.57±0.77 vs 2. 46 ± 0. 59, F = 8. 459, P < 0. 05 ), however, the score of AEC group was lower than that of CCC group on other levels without significant differences (superior margin of the aortic arch:3.36 ±0. 63 vs 3.45 ±0. 60,the right superior lobar bronchus level: 3.94 ±0. 56 vs 3. 95 ±0. 51 ,the right middle lobar bronchus Level: 3.80 ±0. 58 vs 3. 87 ±0. 50,the right inferior pulmonary vein level: 3.72 ±0. 56 vs 3.78 ±0. 53, superior margin of the left diaphragmatic dome level: 3.58 ± 0.63 vs 3.68±0.56,F=0.083-3.380,P > 0.05 ). The MPR image quality of AEC group was better than that of CCC group both on lung window and mediastinum window (Zlung =-2.258, Zmedlastinum=-1.330, P>0.05). For all participants including the underweighted group, the normal group and the overweighted group, the image quality of A1 group was better than that of A2 group without significant differences (the underweighted group: Zlung=0.000, P=1.000, Zmedastinum= 0.000, P=1.000;the normal group: Zlung =-0.062, P=0.950, Zmediastinum =-0.746, P = 0.456; the overweighted group: Zlung = - 1.177, P = 0.239,Zmediastinum =-1.715, P=0.144) both on lung and mediastinum windows, and for the higher BMI participants, a better image quality was obtained in A1 group than in A2 group on the mediastinum window (Z = -1. 715, P = 0. 144). Conclusions The total radiation exposure dose of AEC group is significantly lower than that of CCC group, but no statistical significant differences are observed between both groups in image quality and noise level. The AEC technique is highly recommended in thoracic LDCT scan for screening program, and the SD25 ( SD value = 25) scan protocol is suggested for higher BMI population while the SD30 (SD value = 30) scan protocol for lower BMI population.

Objective To explore the molecular mechanism of dipeptidyl peptidase-4 ( DPP4) in the calcification of human vascular smooth muscle cells(HVSMCs). Methods The osteogenic differentiation of HVSMCs was induced by 200 ng/ ml DPP4 as calcification model. The differentially expressed long non-coding RNAs (lncRNAs) between DPP4 group and control group were analyzed by microarray, and the microarray results of LincRNA ENST00000540293 were validated by real-time PCR. After HVSMCs were incubated with LincRNA ENST00000540293 silencing positive reagent for 48 h, the expressions of calcification-related proteins osteoprotegerin (OPG) and bone morphogenetic protein 2(BMP-2) were detected by Western blotting and the formation of calcified nodules was observed by Alizarin red staining. Results The protein expressions of OPG and BMP-2 in HVSMCs were significantly increased after DPP4 intervention (P <0.05), with the increased formation of calcified nodules. RTqPCR showed that LincRNA ENST00000540293 expression was significantly decreased in DPP4 group as compared with the control group(P<0.05). The expressions of calcification-related proteins OPG and BMP-2 were significantly increased after LincRNA ENST00000540293 silence(P<0.05). Conclusion DPP4 may promote the calcification of HVSMC through inhibiting LincRNA ENST00000540293 expression.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.
