Objective:To investigate the status of clinical nurses′ professional identity and disaster cognition during the post-disaster reconstruction, and to analyze the correlation between the two.Methods:With the convenient sampling method, the 346 nursing staff of the First Affiliated Hospital of Zhengzhou University participated in the disaster reconstruction for the survey, using the general questionnaire, the nurse professional identity scale, the disaster cognition questionnaire for investigation. Pearson correlation was used to analyze the correlation between disaster cognition and professional identity.Results:The disaster cognition during the post-disaster needed to be improved, the choice rate of knowing disaster nursing well was 6.36%-70.23%. Gender had significant statistical significance on the scores of thinking the importance of disaster care training and willingness to join in disaster care continuing education ( t=-2.54 and -2.32, both P<0.05). Position had significant statistical significance on the score of willing to join in the enthusiasm of emergency rescue( F=6.62, P<0.05). Whether have ever participated in disaster training had significant statistical significance on the scores of focusing on the frequency of disasters and understanding the degree of disaster care ( t=5.57, 7.88, both P<0.05). Nurse professional identity level was high during the post-disaster reconstruction, the total score was (121.73 ± 19.75). Whether have ever participated in disaster training had significant statistical significance on the score of professional identity ( t=4.57, P<0.05). And the total score and each dimension score of disaster recognition were positively correlated with the total score and each dimension score of professional identity in nurses ( r values were 0.44-0.53, all P<0.05). Conclusions:The disaster cognition level is still lacking, the professional identity level is high. The disaster cognition affects professional identity levels to a certain extent, so nursing managers should improve the disaster recognition of nursing staff by making targeted strategy, which can not only improve the professional identity levels, but also reserve power for emergency disaster and post-disaster reconstruction reserves.

Cloning of flanking sequences of double-copy gene is a challenge in molecular biology. We developed a method to solve this problem by combining an optimized inverse PCR (iPCR) with TAIL-PCR. First, Southern blotting analysis was used to determine a proper restriction enzyme that could obtain proper-length restriction fragments that contained the target gene. Then optimized iPCR was performed to amplify the restriction fragments that contained the separated copies of the gene. Based on the obtained sequences, TAIL-PCR was performed to amplify further flanking regions of the gene. With this method, we obtained all of the EcoR I restriction fragments (2.2-5.1 kb) and Hind III restriction fragments (8.5-11.7 kb) of mitochondrial atpA gene in cytoplasmic male sterile (CMS) line and maintainer line of Upland cotton. The results showed that this method was an efficient approach to clone flanking sequences of double-copy gene.

Objective:To establish and validate a prognostic model of a contrast-enhanced ultrasound scoring(CEUS)system for evaluating renal artery stenosis(RAS)in the elderly.Methods:This was a single-center retrospective study.A total of 324 elderly RAS patients admitted to Beijing Hospital from October 2017 to July 2020 were randomly assigned into the model group(n=174)and the validation group(150)in a 1∶1 ratio.Clinical and imaging data of patients on admission including general conditions, previous medical history, blood pressure, blood creatinine, renal artery stenosis and cortical blood perfusion in the affected kidney and renal function(GFR)at 1-year follow-up were collected.Univariate and multivariate logistic regression was used to establish a model of the CEUS scoring system.The receiver operating characteristic(ROC)curve and area under the ROC curve(AUC)were used to evaluate prediction accuracy.Clinical application value of the CEUS scoring system model was evaluated via decision curve analysis using a nomogram.Results:Baseline clinical and radiomic data had no significant difference between the model group and the validation group( P>0.05). Multivariate logistic regression analysis results showed that age( OR=1.242, 95% CI: 1.081-1.427, P<0.01), diabetes( OR=1.545, 95% CI: 1.107-2.156, P<0.05), blood pressure( OR=1.328, 95% CI: 1.056-1.670, P<0.05), renal function( OR=2.374, 95% CI: 1.216-3.887, P<0.01)and cortical blood perfusion parameter( OR=2.646, 95% CI: 1.553-6.369, P<0.01)were risk factors for the deterioration of renal function during 1 year follow-up.Based on these results, a nomogram for the CEUS scoring system model was drawn, and its consistency index, the C-Index, was 0.725(95% CI: 0.653-0.776). The AUC of the CEUS scoring system was 0.824 and the Youden index was 0.711 in the model group, with a specificity of 0.774 and a sensitivity of 0.837.The AUC of the CEUS scoring system was 0.853 and the Youden index was 0.715 in the validation group, with a specificity of 0.684 and a sensitivity of 0.889.There was no significant difference in ROC curve between the two groups( D=1.387, P>0.05). In addition, calibration charts of the two models showed that the calibration curve of the CEUS scoring system was close to the standard curve, with no statistically significant difference( P>0.05). Conclusions:The CEUS scoring system model can be used to predict the risk of worsening renal function in elderly RAS patients during 1-year follow-up.

Objective:To investigate the imaging characteristics on contrast-enhanced ultrasound(CEUS)of carotid plaque instability and their correlation with histopathological changes in elderly patients.Methods:Twenty-three patients undergone carotid endarterectomy(CEA)at the Department of Neurosurgery of Beijing Hospital from June 2018 to November 2020 were retrospectively enrolled, including 27 males and 5 females, aging from 60 to 87(68.1±6.3)years.They were diagnosed with moderate to severe carotid artery stenosis(50%-99%)based on digital subtraction angiography(DSA).Carotid artery CEUS was conducted before surgery, and HE staining and CD34 immunohistochemical staining were used to record histopathological scores and microvessel density(MVD)counts.Results:The mean pathological score and MVD count were 2.46±0.66 and 37.17±12.88 for 32 cases with hypoechoic patterns, 22.42±0.55 and 38.06±13.66 for 18 cases with mixed echo patterns, and 2.75±0.35 and 23.50±9.192 for 2 cases with strong echo patterns, respectively.CEUS grading was positively correlated with histopathology score and MVD count( r=0.53、0.76, all P<0.01). Conclusions:Low echo and mixed echo plaques are more unstable than strong echo plaques.CEUS can be used to comprehensively assess the vulnerability of atherosclerotic plaques and to decide the optimal surgical time for patients with carotid atherosclerotic plaque stenosis.

Purpose:
Mixed-lineage leukemia protein 4 (MLL4/KMT2D) is a histone methyltransferase, and its mutation has been reported to be associated with a poor prognosis in many cancers, including lung cancer. We investigated the function of MLL4 in lung carcinogenesis.
Materials and Methods:
RNA sequencing (RNA-seq) in A549 cells transfected with control siRNA or MLL4 siRNA was performed. Also, we used EdU incorporation assay, colony formation assays, growth curve analysis, transwell invasion assays, immunohistochemical staining, and in vivo bioluminescence assay to investigate the function of MLL4 in lung carcinogenesis.
Results:
We found that MLL4 expression was downregulated in non–small cell lung cancer (NSCLC) tissues compared to adjacent normal tissues and tended to decrease with disease stage progression. We analyzed the transcriptomes in control and MLL4- deficient cells using high-throughput RNA deep sequencing (RNA-seq) and identified a cohort of target genes, such as SOX2, ATF1, FOXP4, PIK3IP1, SIRT4, TENT5B, and LFNG, some of which are related to proliferation and metastasis. Our results showed that low expression of MLL4 promotes NSCLC cell proliferation and metastasis and is required for the maintenance of NSCLC stem cell properties.
Conclusion
Our findings identify an important role of MLL4 in lung carcinogenesis through transcriptional regulation of PIK3IP1, affecting the PI3K/AKT/SOX2 axis, and suggest that MLL4 could be a potential prognostic indicator and target for NSCLC therapy.

Objective:To systematically evaluate the efficacy of different kinds of smoking cessation drugs by network Meta-analysis.Methods:Literature was retrieved from PubMed, Web of Science, Embase, Cochrane Library, CBM, CNKI, VIP, Wan fang database, from the establishment of the database to November 2022, and randomized controlled trials (RCT) about bupropion, varenicline, nicotine replacement therapy (NRT) versus placebo in the treatment of smoking patients were collected. After data extraction from included literature which met inclusion criteria, and quality evaluation with Cochrane 5.1 risk bias evaluation tool, network Meta-analysis was performed by Stata15.1 software.Results:A total of 19 RCTs, involving 6106 patients and three interventions measures (bupropion, varenicline, NRT) and one control measure (placebo) were included. The results of network Meta-analysis showed that in terms of short-term abstinence rate, varenicline [ OR=4.21, 95% CI (2.32, 7.63)], bupropion [ OR=2.81, 95% CI(1.05, 7.54)] were better than placebo ( P<0.05). The surface under the cumulative ranking area (SUCRA): varenicline (90.2%)>bupropion (64.8%)>NRT (41.7%)>placebo (3.2%). In terms of the long-term abstinence rate, varenicline [ OR=3.06, 95% CI (1.59, 5.90)], NRT [ OR=3.39, 95% CI (2.20, 5.21)] were better than placebo ( P<0.05). SUCRA: varenicline (83.8%)>NRT (73.9%)>bupropion (37.2%)>placebo (5.2%). Conclusion:The existing evidence shows that compared with bupropion, NRT, varenicline has the best effect on quitting smoking, but more high-quality randomized trial evidence is needed for verification.
