Objective:To explore the status quo of job satisfaction, character advantage and subjective well-being of nursing staff, and to explore the relationship among the three, so as to provide theoretical basis for improving the subjective well-being of medical staff.Methods:Using cluster random sampling method, 582 nursing staff in Jinzhou City of Liaoning Province were selected as the survey objects. The General Information Questionnaire, Minnesota Satisfaction Questionnaire, Character Strengths Scale and Subjective Well-being Scale were used to investigate the respondents. The mediating effect of character strengths on job satisfaction and subjective well-being was analyzed by structural equation model. The mediating effect was analyzed and verified by bootstrap method.Results:The score of Minnesota satisfaction questionnaire, Character Strengths Scale and Subjective Well-being Scale of nursing staff were 70.5 ± 10.8, 45.0 ± 6.8 and 24.2 ± 6.3 respectively. The results of correlation analysis showed that there was a positive correlation between the total score of job satisfaction and the total score of character strengths of nursing staff ( r=0.214, P<0.01), and the total score of subjective well-being ( r=0.373, P<0.01). The total score of subjective well-being was positively correlated with the total score of character strengths ( r=0.123, P<0.01). Conclusions:The character strengths of nursing staff plays a mediating role between job satisfaction and subjective well-being.

Through the development of the guidance for case handling of radiological health law enforcement, health supervisors are instructed to accurately grasp the key points of law enforcement and case handling and standardize the process of collecting evidence and law application to ensure the correct implementation of administrative penalty. This article explains the structure and content of the guidance for case handling of radiological health law enforcement by taking the case of arranging radiation workers who have not undergone an occupational health examination to engage in the radiological occupational-disease-inductive operation in medical institutions as an example.

Objective:To investigate the correlation between plasma microRNA (miR)-122, miR-33a and the severity of coronary artery disease in patients with type 2 diabetes mellitus (T2DM) and coronary heart disease.Methods:The clinical data of 196 patients with T2DM from January 2019 to October 2021 in Xuzhou First People′s Hospital were retrospectively analyzed. Among them, 81 cases were complicated with coronary heart disease (combined group), 115 cases were not complicated with coronary heart disease (control group). The plasma levels of miR-122 and miR-33a were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction, the plasma level of N-terminal B-type natriuretic peptide precursor (NT-proBNP) was detected by enzyme-linked immunosorbent assay. In combined group, the number of coronary artery lesions was determined according to the results of coronary angiography, and Gensini score was evaluated. Linear regression model was used to analyze the relationship between plasma miR-122, miR-33a and NT-proBNP levels with the incidence of coronary heart disease in patients with T2DM. Receiver operating characteristic (ROC) curve was used to analyze the plasma miR-122 and miR-33a in predicting efficiency of coronary heart disease in patients with T2DM. In combined group, Spearman correlation method was used to analyze the relationship between plasma miR-122, miR-33a and the number of coronary artery lesions, and Pearson correlation method was used to analyze the relationship between plasma miR-122, miR-33a and plasma NT proBNP, Gensini score.Results:The plasma miR-122, miR-33a and NT-proBNP in combined group were significantly higher than those in control group: 5.76 ± 1.35 vs. 1.18 ± 0.33, 1.39 ± 0.37 vs. 0.65 ± 0.11 and (786.87 ± 156.39) ng/L vs. (103.45 ± 19.27) ng/L respectively, and there were statistical differences ( P<0.01). Linear regression result showed that plasma miR-122, miR-33a, and NT-proBNP were positive correlation with occurrence of coronary heart disease in patients with T2DM ( P<0.01); ROC curve analysis result showed that the area under curve of plasma miR-122, miR-33a and combination in predicting coronary heart disease in patients with T2DM were 0.816, 0.845 and 0.912 respectively (95% CI 0.744 to 0.865, 0.768 to 0.892 and 0.836 to 0.967). Coronary angiography result showed that there were 46 cases of single vessel lesions, 25 cases of double vessel lesions and 10 cases of three vessel lesions. The plasma miR-122, miR-33a, NT-proBNP and Gensini score in patients with three vessel lesions were significantly higher than those in patients with double vessel lesions and patients with single vessel lesions: 6.52 ± 0.96 vs. 4.95 ± 0.85 and 3.74 ± 0.52, 1.45 ± 0.31 vs. 1.06 ± 0.25 and 0.81 ± 0.13, (829.78 ± 62.59) ng/L vs. (627.48 ± 47.12) and (502.64 ± 38.24) ng/L, (63.89 ± 12.71) scores vs. (42.18 ± 6.03) and (22.36 ± 2.41) scores, the indexes in patients with double vessel lesions were significantly higher than those in patients with single vessel lesions, and there were statistical differences ( P<0.05). In combined group, Spearman correlation analysis result showed that the plasma miR-122 and miR-33a were positive correlation with the number of coronary artery lesions ( r = 0.879 and 0.825, P<0.05); Pearson correlation analysis result showed that the plasma miR-122 and miR-33a were positive correlation with the plasma NT-proBNP and Gensini score (miR-122: r = 0.896 and 0.788, miR-33a: r = 0.871 and 0.765; P<0.05). Conclusions:The plasma levels of miR-122 and miR-33a are related to the occurrence of coronary heart disease and severity of coronary artery disease in patients with T2DM, which may be used to guide the prevention and treatment of coronary heart disease in patients with T2DM.

Objective:In this study, a gait acquisition and analysis system is developed to provide a cheap, easy-to-use solution for quantitative recording and analysis of patients' gaits.Methods:From April 2017 to October 2018, we collected the gait data of 19 patients with knee osteoarthritis and 19 healthy volunteers in the orthopaedic outpatient department. Among 19 patients, there were 9 males and 10 females, aged 50.1±9.4 years old. Among 19 healthy volunteers, there were 8 males and 11 females, aged 50.7±10.3 years old. Then, from the collected gait data, the static gait features such as gait speed, step length, stride, and dynamic gait features were automatically calculated, and the statistical difference analysis was finished to determine the correlation between these quantitative gait features and knee osteoarthritis.Results:Firstly, the gait data collected by the depth camera was compared with the data from the multi infrared camera-based motion analysis system (gold standard). The average angle error of the collected knee joint angle was 0.98 degrees, which proved the correctness of the gait data recorded by the depth camera. The statistical difference analysis of gait characteristics between the patient group and the healthy group showed that the gait characteristics with P<0.05 included: gait speed ( r=-0.922, P<0.001), step length ( r=-0.897, P=0.004), stride ( r=-0.914 , P<0.001), dynamic characteristics of angle of knee joint ( r=0.775, P=0.001). Conclusion:The gait acquisition and analysis system based on the depth camera can accurately record and store the gait data of the patients with knee osteoarthritis. Moreover, the extracted quantitative gait features have statistical differences between the patients and the healthy group, which is helpful for the gait analysis of bone joint.

Objective: To investigate differentially expressed genes and related signaling pathways in patients with dermatomyositis/clinical amyopathic dermatomyositis (DM/CADM) complicated by interstitial lung disease or malignant tumors. Methods: From January 2017 to January 2018, 27 DM/CADM patients were enrolled from Department of Dermatology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, and divided into 3 groups according to the complications: 10 with interstitial lung disease, 8 with malignant tumors, and 9 without interstitial lung disease or malignant tumors. Meanwhile, 7 healthy controls were enrolled into this study. High-throughput RNA sequencing was performed to screen differentially expressed genes in peripheral blood in the above 4 groups. Then, these genes were subjected to gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results: Compared with the healthy controls, 4 820 up-regulated genes and 137 down-regulated genes were identified in DM/CADM patients; GO analysis revealed 49 significantly enriched items in the DM/CADM patients, 37 (75.5%) of which were associated with biological processes; KEGG analysis showed that differentially expressed genes were mainly enriched in infection-, tumor- and immune-related pathways in DM/CADM patients. Compared with the patients without interstitial lung disease or malignant tumors, 272 up-regulated genes and 158 down-regulated genes were identified in the patients with interstitial lung disease; GO analysis revealed 157 significantly enriched items, 114 (72.6%) of which were associated with biological processes; KEGG analysis showed that differentially expressed genes were mainly enriched in bacterial infection- and autoimmune/inflammatory-related pathways in the patients with interstitial lung disease. Compared with the patients without interstitial lung disease or malignant tumors, 398 up-regulated genes and 68 down-regulated genes were identified in the patients with malignant tumors; GO analysis revealed 117 significantly enriched items, 94 (80.3%) of which were associated with biological processes; KEGG analysis showed that differentially expressed genes were mainly enriched in glycosylation-, metabolism- and tumor-related signaling pathways in the patients with malignant tumors. Conclusions Differences existed in transcriptomes and pathways between the DM/CADM patients and healthy controls, as well as between the patients with interstitial lung disease or malignant tumors and patients without these complications. Bacterial infection- and cytokine/chemokine-related pathways were significantly enriched in the patients with DM/CADM complicated by interstitial lung disease, while those pathways related to glycosylation, protein metabolism, angtigen presentation and cytotoxic effects of natural killer cells were significantly enriched in the patients with DM/CADM complicated by malignant tumors.

Objective: To investigate the clinical features of anti-signal recognition particle (SRP) antibody-positive patients with dermatomyositis/clinically amyopathic dermatomyositis (DM/CADM) . Methods: Clinical data were collected from 90 patients with DM/CADM, who were hospitalized at the Department of Dermatology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from June 2015 to July 2017. Immunoblotting assay was performed to determine the serum level of anti-SRP antibody in these patients. Statistical analysis was carried out using t test and Chi-square test. Results: Of the 90 patients with DM/CADM, 11 (12.2%) were positive for serum anti-SRP antibody, including 6 with DM and 5 with CADM. Among 82 adult patients with DM/CADM, the prevalence of malignant tumors was significantly higher in the patients with anti-SRP antibody than in those without (7/9 vs. 31.5%[23/73], χ² = 7.394, P = 0.006) . The 11 patients with anti-SRP antibody had typical DM skin lesions, and their cutaneous dermatomyositis disease area and severity index (CDASI) was 18.1 ± 2.9. The prevalence of "angel wings sign" (aliform erythema on the trunk) was significantly higher in the patients with anti-SRP antibody than in those without (7/11 vs. 29.9%[20/67], Fisher′s exact test, P = 0.028) . The positive rate of antinuclear antibody was significantly higher in the patients with anti-SRP antibody than in those without (4/8 vs. 16.7%[13/78], χ² = 6.053, P = 0.014) . Magnetic resonance imaging of muscles of both thighs of the 10 patients with anti-SRP antibody (6 with DM and 4 with CADM) showed the presence of abnormal signals in the thigh muscle group in 8, swelling of the muscle group in 2, subcutaneous edema in 2, myofascial swelling in 1, and no abnormities in 2. No interstitial lung disease or myocardial involvement was observed in the patients with anti-SRP antibody. Conclusions The anti-SRP antibody-positive patients with DM/CADM showed a high prevalence of "angel wings sign" , and a high risk of malignant tumors. Early detection of the anti-SRP antibody in patients with DM/CADM is helpful to predict the occurrence of malignant tumors.

Background and objective Epidermal growth factor receptor (EGFR) and KRAS gene are important driver genes of non-small cell lung cancer (NSCLC).The studies are mainly focused on detection ofEGFR gene for advanced NSCLC,and the mutation feature of EGFR and KRAS gene in early NSCLC tissue is unknown.This study aims to investigate the mutations of EGFR and KRAS gene in NSCLC,and the relationship between the genotype and clinicopathologic features.Methods The hotspot mutations in EGFR and KRAS gene in 754 tissue samples of stage Ⅰ-Ⅲa NSCLC from Department of Pathology,Peking Union Medical College Hospital were detected by modified amplification refractory mutation system (ARMS) real-time PCR kit,and analyzed their correlation with clinical variables.Results The hotspot mutation rates in EGFR and KRAS were 34.5％ and 13.1％ respectively,and there were EGFR-KRAS double mutations in 3 samples.The mutation rate of EGFR was higher in females than that in males (39.5％ vs 29.4％,P=0.076),significantly increased in adenocarcinomas (38.7％) compared to that in the other forms of NSCLC (P＜0.01),but still lower than that reported in some Asian studies of advanced adenocarcinoma (-50％).Meanwhile,the mutation rate of KRAS was remarkably higher in males than that in females (16.6％ vs 9％,P=0.048),increased in adenocarcinomas compared to that in the other forms of NSCLC,but the difference was not significant (P=0.268).Samples harbored EGFR mutation were younger than those harbored KRAS mutation (P=0.031,5),and had significant difference in gender between the two groups (P＜0.01).Conclusion The mutation rate of EGFR in stag Ⅰ-Ⅲa NSCLC patients was lower than that in advanced NSCLC patients.And the percentage of the NSCLC patients with EGFRKRAS double mutations is 0.9％.

OBJECTIVETo reduce health-related threats of heat waves, interventions have been implemented in many parts of the world. However, there is a lack of higher-level evidence concerning the intervention efficacy. This study aimed to determine the efficacy of an intervention to reduce the number of heat-related illnesses.

METHODSA quasi-experimental design was employed by two cross-sectional surveys in the year 2014 and 2015, including 2,240 participants and 2,356 participants, respectively. Each survey was designed to include one control group and one intervention group, which conducted in Licheng, China. A representative sample was selected using a multistage sampling method. Data, collected from questionnaires about heat waves in 2014 and 2015, were analyzed using a difference-in-difference analysis and cost effectiveness analysis. Outcomes included changes in the prevalence of heat-related illnesses and cost-effectiveness variables.

RESULTSRelative to the control participants, the prevalence of heat-related illness in the intervention participants decreased to a greater extent in rural areas than in urban areas (OR=0.495 vs. OR=1.281). Moreover, the cost-effectiveness ratio in the intervention group was less than that in the control group (US$15.06 vs. US$15.69 per participant). Furthermore, to avoid one additional patient, the incremental cost-effectiveness ratio showed that an additional US$14.47 would be needed for the intervention compared to when no intervention was applied.

CONCLUSIONThe intervention program may be considered a worthwhile investment for rural areas that are more likely to experience heat waves. Meanwhile, corresponding improving measures should be presented towards urban areas. Future research should examine whether the intervention strategies could be spread out in other domestic or international regions where heat waves are usually experienced.
