Objective:To investigate the current situation of occupational burnout among bus drivers in Wuhu City and analyze its influencing factors.Methods:A survey was conducted in 1 388 bus drivers in Wuhu City from Sep to Nov 2022 using the general information questionnaire,the Maslach Burnout Inventory-General Survey(MBI-GS),and the Pittsburgh Sleep Quality Index(PSQI).Multivariable logistic regression analysis was used to analyze the influencing factors of occupational burnout in bus drivers.Spearman correlation analysis was used to analyze the correlation between occupational burnout and sleep quality.Results:Among 1 388 bus drivers,642(46.3%)were positive for occupational burnout,and 139(10.0%)were found to have sleep disorders.Multivariable logistic regression analysis showed that longer bus driving experience(OR=1.873,95%CI:1.325-2.648),lower monthly income(OR=0.376,95%CI:0.158-0.774),higher smoking frequency(OR=1.313,95%CI:1.188-2.163),higher drinking frequency(OR=1.342,95%CI:1.018-1.769),lower weekly physical exercise frequency(OR=0.367,95%CI:0.243-0.555),and poor sleep quality(OR=13.110,95%CI:7.284-23.594)were the influencing factors of bus driver occupational burnout(P＜0.05).Spearman correlation analysis showed that the total score of occupational burnout and its dimension scores were positively correlated with the total score of sleep quality and its dimension scores(rs=0.12-0.83,P＜0.01).Conclusion:The problem of occupational burnout among bus drivers in Wuhu City is relatively serious,and a part of people have sleep problems,which should be paid great attention to and active measures should be taken in time.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective:To establish a matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) method for the direct detection of serum M protein without antibody enrichment, and to assess its detection performance.Methods:Method establishment. A total of 712 waste serum samples were collected from patients who applied for the M protein identification test in Beijing Chaoyang Hospital affiliated to Capital Medical University. The immunoglobulin light chain was obtained by reduction of IgG and IgA by TCEP, and the detection method was preliminarily determined. The waste serum samples from 20 healthy people were collected to determine the range of mass-to-charge ratios of κ and λ light chain ions. 8 parallel tubes and 8 batches were set up for intra-and inter-batch reproducibility evaluation. 10-fold, 100-fold and 200-fold diluted M protein from 23 positive samples were detected by established MALDI-TOF MS method, and its sensitivity was evaluated. 3 methods of IFE, SPE and MALDI-TOF MS were used to detect M protein simultaneously, and the coincidence rate between MALDI-TOF MS and IFE and SPE was calculated.Results:The repeatability within and between batches was 100%, respectively. The original, 10-, 100-and 200-fold dilutions of 23 M protein-positive samples were determined, and the detection limit of MALDI-TOF MS for M protein was 0.06-0.18 g/L. IFE as the gold standard, the overall coincidence rates of SPE and MALDI-TOF MS were 85.9% and 92.3%, respectively, and the positive coincidence rates of SPE and MALDI-TOF MS were 72.8% and 99.7%, respectively, of the 712 samples. Among the different types of M-proteins, MALDI-TOF-MS agreed 100% with IFE M-protein results for IgA, IgD, IgM, free light chain type and biclonal group, while the agreements of SPE for IgM, IgA and free light chain samples were only 66.7%, 58% and 19.5%, respectively. One positive sample in the IgG group was not detected by MALDI-TOF MS. 23 M-proteins positive samples were diluted by original, 10, 100 and 200 times to access the sensitivity of MALDI-TOF MS method. The coincidence rate of MALDI-TOF MS was 100% and IFE was 96% at 10-fold dilution. The coincidence rate of IFE was 28% and 23% of MALDI-TOF MS at 100-fold and 200-fold dilution, respectively.Conclusions:A MALDI-TOF MS method for the detection of serum M-proteins was successfully established. This method has the advantages of high detection throughput, fast speed, good sensitivity, specificity and coincidence rate.

Objective:To investigate the effects of different production processes on sensitization responses to human diploid cell rabies vaccines.Methods:This study randomly collected 360 serum samples in clinical trials of four rabies vaccines with different production processes. Total IgE levels at different time points were detected by ELISA. SPSS19.0 software was used for statistical analysis.Results:Total IgE test results showed that the seropositive rate was 20% (6/30) for all four vaccines. The lowest mean value of total IgE was 9 IU/ml and the highest was 210 IU/ml. Repeated measures analysis of variance showed that there was no significant difference in total IgE levels at different sampling time points ( P=0.284), and the total IgE level in people injected with multistep concentrated human diploid cell rabies vaccine was significantly below that in people immunized with Vero cell rabies vaccine ( P=0.024). Conclusions:Increasing the immune dosage of human rabies vaccine could not result in a rise in total IgE. Human diploid cell rabies vaccines had good safety as the production process could remove most of allergenic impurities.

Depression is a common psychiatric symptom in cerebral small vessel disease (CSVD), which has a certain relationship with impairment of cognitive function and can significantly increase the mortality and morbidity of CSVD patients. The occurrence of CVSD-associated depression is less related to psychological stress, but is associated with the impairment of the brain's emotional circuit. This article reviewed the correlation between the imaging features of CVSD and the occurrence and development of depression in recent years, and the neuroimaging mechanism of depression associated with CVSD. Many literatures have shown that deep white matter hyperintensities and asymptomatic lacunar infarction in the basal ganglia are independent risk factors for depression in CSVD, and the reduction of local brain volume is associated with depression. The neuroimaging mechanism of depression associated with CSVD suggests that the occurrence of depressive symptoms is related to the neural circuits in the lobar cortex-subcortical limbic area. These findings provide clues for exploring the neuropathological mechanisms and specific treatment methods of depression associated with CVSD.

Background::Sepsis is a systemic inflammatory syndrome induced by several infectious agents. Multiple organs are affected by sepsis, including the liver, which plays an important role in metabolism and immune homeostasis. Fibroblast growth factors (FGFs) participate in several biological processes, although the role of FGF5 in sepsis is unclear. Methods::In this study, lipopolysaccharide (LPS) was administrated to mice to establish a sepsis-induced liver injury. A similar in vitro study was conducted using L-02 hepatocytes. Western blot and immunohistochemistry staining were performed to evaluate the FGF5 expression level in liver tissues and cells. Inflammatory cell infiltrations, cleaved-caspase-3 expressions, reactive oxygen species and levels of inflammatory cytokines were detected by immunofluorescence, dihydroethidium staining, and reverse transcription quantitative polymerase chain reaction analysis, respectively. Flow cytometry was used to detect the apoptosis level of cells. In addition, ribonucleic acid (RNA)-sequencing was applied to explore the possible mechanism by which FGF5 exerted effects. Results::LPS administration caused FGF5 down-regulation in the mouse liver as well as in L-02 hepatocytes. Additionally, with FGF5 overexpression, liver injury and the level of hepatocyte apoptosis were ameliorated. Further, RNA sequencing performed in hepatocytes revealed the phosphoinositide-3-kinase/protein kinase B (PI3K/AKT) pathway as a possible pathway regulated by FGF5. This was supported using an inhibitor of the PI3K/AKT pathway, which abrogated the protective effect of FGF5 in LPS-induced hepatocyte injury. Conclusion::The anti-apoptotic effect of FGF5 on hepatocytes suffering from LPS has been demonstrated and was dependent on the activation of the PI3K/AKT signaling pathway.

Objective:To explore the feasibility and effect of evacuated blood collection combined with non sealing technique in the collection of pharmacokinetic blood samples in phase I clinical trials.Methods:Using convenient sampling method, 60 patients in phase I clinical trial who were admitted between November 2017 and October 2019 were selected as the research objects, and were divided into control group and improvement group according to the admission sequence. Among them, 31 patients collected from November 2017 to October 2018 were taken as the control group, and blood samples were collected in 390 tubes by syringe in open indwelling needle; from November 2018 to October 2019, 29 patients were selected as the improvement group, and 388 blood samples were collected by evacuated blood collection combined with non sealing technique in the open indwelling needle. The incidence of indwelling needle plugging, hemolysis of blood samples and the duration of single blood sampling were compared between the two groups.Results:In the incidence of indwelling needle plugging, the improvement group was 3.09% (12/388) , the control group was 2.05% (8/390) , there was no significant difference between the two groups (χ 2=0.800, P>0.05) ; in the incidence of hemolysis of blood samples, the improvement group was 2.66% (10/376) , the control group was 7.33% (28/382) , the difference between the two groups was statistically significant (χ 2=7.857, P<0.01) ; the improvement group was (29.40±1.99) seconds in the duration of single blood sampling, the control group was (40.74±0.88) seconds, the difference between the two groups was statistically significant ( t=101.15, P<0.01) . Conclusions:In the collection of pharmacokinetic blood samples of phase I clinical trials of new drugs, evacuated blood collection combined with non sealing technique can not only protect the blood vessels of the subjects, but also control the time of intensive blood collection within 12 hours, save the operation time of blood collection and guarantee the quality of blood samples. It is worth popularizing to ensure the scientific and standard test.

In the past ten years, the research and application of microbiome has continued to increase. The microbiome has gradually become the research focus in the fields of life science, environmental science, and medicine. Meanwhile, many countries and organizations around the world are launching their own microbiome projects and conducting a multi-faceted layout, striving to gain a strategic position in this promising field. In addition, whether it is scientific research or industrial applications, there has been a climax of research and a wave of investment and financing, accordingly, products and services related to the microbiome are constantly emerging. However, due to the rapid development of microbiome sequencing and analysis related technologies and methods, the research and application from various countries have not yet unified on the standards of technology, programs, and data. Domestic industry participants also have insufficient understanding of the microbiome. New methods, technologies, and theories have not yet been fully accepted and used. In addition, some of the existing standards and guidelines are too general with poor practicality. This not only causes obstacles in the integration of scientific research data and waste of resources, but also gives related companies unfair competition opportunity. More importantly, China still lacks national standards related to the microbiome, and the national microbiome project is still in the process of preparation. In this context, the experts and practitioners of the microbiome worked together and developed the consensus of experts. It can not only guide domestic scientific research and industrial institutions to regulate the production, learning and research of the microbiome, the application can also provide reference technical basis for the relevant national functional departments, protect the scale and standardized corporate company's interests, strengthen industry self-discipline, avoid unregulated enterprises from disrupting the market, and ultimately promote the benign development of microbiome-related industries.

Objective To analyze the epidemiological surveillance results of human brucellosis in Shanxi Province from 2012 to 2017,to know the epidemic status of brucellosis,and to provide evidence for prevention and control of brucellosis.Methods Incidence date and surveillance date of disease outbreaks in Shanxi Province from 2012 to 2017 were collected,the retrospective analysis method was used to analysis the "three distribution" of brucellosis,outbreak situation and the results of serological and pathogenic surveillance in the 4 surveillance stations.Results A total of 36 220 brucellosis cases were reported from 2012 to 2017,the average incidence was 16.62/100 000;8 540 brucellosis cases were reported in 2014,with incidence 23.53/100 000;a total of 23 197 cases of brucellosis were reported mainly in Datong,Shuozhou,Jinzhong and Xinzhou,accounting for 64.04％ of the province total.The onset was seasonal,and the peak of the epidemic was from March to August,accounting for 67.23％ (24 350/36 220).The brucellosis cases were mainly youth (23 084),male (28 317),farmers and herdsman (32 616).In the 4 surveillance stations of the brucellosis,39 140 cases were investigated,of which 10 536 cases did serological test,in which 585 were positive for Brucella (5.55％).The highest positive rate of serological test was 9.50％ (226/2 738) which was found in Tianzhen.A total of 626 samples carried out pathogen culture,in which 107 strains of brucellosis were detected,the detection rate was 17.09％,and 106 strains Brucella were melitensis biovar 3 of the total strains except 1 mutant.Conclusions The reported incidence in Shanxi Province is in a decline tendency,but the situation of brucellosis epidemic is still relatively serious.It is suggested that the surveillance work should be strengthened;the epidemic situation of brucellosis should be mastered in time and effectively controlled.

Objective To explore the changes of whole brain white matter ( WM) structural net-work topological property in patients with schizophrenia (SP) and the associations between WM networks to-pological efficiency and clinical variables in patients. Methods Deterministic tractography was used to con-struct the WM networks of 59 patients with SP ( patients group) and 41 age-, handedness-, and gender-matched healthy controls (HCs),and graph theoretical methods were applied to investigate abnormalities in the global and nodal properties of the WM network in these patients. Partial correlation analysis was used to analyze the relationship between global and nodal properties of the WM network and clinical variables in pa-tients with SP. Results Both the patients with SP and HCs showed small-world organization of the WM net-works. However,compared with HCs,the patients with SP exhibited significant abnormal global topology,in-cluding increased shortest path length ( t=7. 95, P=0. 0001) and decreased global efficiency ( 30. 83 ± 16. 08,8. 25±6. 13,t=-9. 81,P=0. 002),clustering coefficiency (0. 03±0. 01,0. 02±0. 01,t=-4. 48,P=0. 0003),the average clustering coefficiency (t=-8. 28,P=0. 002),the small-worldness (3. 92±0. 79,2. 79 ±0. 56,t=-7. 82,P=0. 001) of their WM structural networks(all P<0. 005,FDR corrected). Further,the patients with SP showed a reduction in nodal efficiency predominately in the cingulate gyrus ( t=-4. 11, P=0. 000),superior occipital gyrus ( t=-6. 05, P=0. 002), superior temporal gyrus ( t=-10. 46, P=0. 001),middle temporal gyrus (t=-10. 38,P=0. 000),thalamus (t=-6. 10,P=0. 000) and putamen ( t=-8. 38,P=0. 000) (P<0. 005,FDR corrected). Partial correlation results showed that there was no signifi-cant correlation between global topological properties,node efficiency and clinical symptoms in patients group (Eglob:r=-0. 14,P=0. 279;Eloc:r=-0. 06,P=0. 628;Lp:r=0. 28,P=0. 031;Cp:r=0. 27,P=0. 043;λ:r=-0. 18,P=0. 166;γ:r=-0. 29,P=0. 026;σ:r=0. 26,P=0. 048;nEglob:r=0. 36,P=0. 005;nEloc:r=0. 02,P=0. 901). Conclusions The patients with SP exhibit the abnormal of whole brain WM structural network topological property and the node efficiencies of cortico-striato-thalamo circuitry are significantly re-duced.
