Objective? To retrieve and analyze the related researches on intensive care unit(ICU) physical environment from 2013 to 2017, and to provide reference for further improvement of the physical environment and quality of medical and nursing care in ICU. Methods? Relevant literature on ICU physical environment included from 2013 to 2017 by the China National Knowledge Infrastructure(CNKI), Wanfang Data Knowledge Service Platform, VIP Database for Chinese Technical Periodicals, Sinomed, Pubmed, Web of Science,and Scopus database were retrieved and analyzed bibliometrically on the internal and external features of the articles by Excel and CiteSpace software. Results? A total of 287 domestic and oversea papers on ICU physical environment were retrieved, the number of published articles showed an overall stable trend. The biggest number of published articles went to Guangdong Province, accounting for 14.1% of the articles in Chinese language. The United States had the biggest number of published papers in English language (43.8%). Literature journals mainly focused on infection control, critical medicine and critical care nursing journals, with the largest number of articles published by a single author(23.0%). The main types of research were clinical research (79.1%), fund-supported literature accounted for 26.5% of all the articles, and research directions were mainly about infection (40.0%), "nosocomial infection" and "pathogenic bacteria", "environment" and"object surface", "premature infant" and "growth and development", "sleep" and "noise" were closely related. Conclusions? The researches on ICU physical environment involves aspects including object surface, noise, light, air quality, temperature and ward design. Infection control in ICU environment and the influences of ICU physical environment on patient's biological rhythm and the growth and development of preterm infants are hot research issues in recent years. However, the geographical distribution of research is not balanced,and the overall quality of research evidence needs to be improved.

Background::Radiation (IR)-induced DNA damage triggers cell cycle arrest and has a suppressive effect on the tumor microenvironment (TME). Wee1, a cell cycle regulator, can eliminate G2/M arrest by phosphorylating cyclin-dependent kinase 1 (CDK1). Meanwhile, programed death-1/programed death ligand-1 (PD-1/PDL-1) blockade is closely related to TME. This study aims to investigate the effects and mechanisms of Wee1 inhibitor AZD1775 and anti-PD-1 antibody (anti-PD-1 Ab) on radiosensitization of hepatoma.Methods::The anti-tumor activity of AZD1775 and IR was determined by 3-(4,5-dimethylthiazol-2-y1)-2,5-diphenyltetrazolium bromide (MTT) assay on human and mouse hepatoma cells HepG2, Hepa1-6, and H22. The anti-hepatoma mechanism of AZD1775 and IR revealed by flow cytometry and Western blot in vitro. A hepatoma subcutaneous xenograft mice model was constructed on Balb/c mice, which were divided into control group, IR group, AZD1775 group, IR + AZD1775 group, IR + anti-PD-1 Ab group, and the IR + AZD1775 + anti-PD-1 Ab group. Cytotoxic CD8 + T cells in TME were analyzed by flow cytometry. Results::Combining IR with AZD1775 synergistically reduced the viability of hepatoma cells in vitro. AZD1775 exhibited antitumor effects by decreasing CDK1 phosphorylation to reverse the IR-induced G2/M arrest and increasing IR-induced DNA damage. AZD1775 treatment also reduced the proportion of PD-1 +/CD8 + T cells in the spleen of hepatoma subcutaneous xenograft mice. Further studies revealed that AZD1775 and anti-PD-1 Ab could enhance the radiosensitivity of hepatoma by enhancing the levels of interferon γ (IFNγ) + or Ki67 + CD8 T cells and decreasing the levels of CD8 + Tregs cells in the tumor and spleen of the hepatoma mice model, indicating that the improvement of TME was manifested by increasing the cytotoxic factor IFNγ expression, enhancing CD8 + T cells proliferation, and weakening CD8 + T cells depletion. Conclusions::This work suggests that AZD1775 and anti-PD-1 Ab synergistically sensitize hepatoma to radiotherapy by enhancing IR-induced DNA damage and improving cytotoxic CD8 + T cells in TME.

ObjectiveTo analyze the satisfaction of service recipients with the preliminary assessment service of the unified elderly care needs evaluation in Shanghai， so as to provide reference for further optimization of the service system. MethodsA multi-stage random sampling method was employed to recruit participants. A total of 110 individuals who had received unified elderly care needs evaluation service in six districts of Shanghai were investigated using a structured questionnaire. SPSS 25.0 was used to analyze the data. Univariate analyses were conducted using the Chi-square test and Fisher’s precision probability test， while multivariate analysis was performed using ordinal regression. ResultsThere were differences in satisfaction with various aspects of the preliminary assessment process among participants from different areas， with those from outer suburbs generally exhibiting lower satisfaction （P<0.01）. Multivariate analysis results indicated that satisfaction with the timing of the preliminary assessment was related to the service recipients’ residential area and their primary source of income； satisfaction with the service attitude and capability of the assessment personnel was only related to the residential area. Satisfaction with the preliminary evaluation results was related to the participants’ marital status， educational level， income level， and the specific rating results. ConclusionThe satisfaction level with the preliminary assessment of the unified elderly care needs assessment in Shanghai is relatively high. In the process of evaluation， a deeper analysis and exploration of individual needs based on various personal information are essential to ensure the appropriateness of the provided elderly care services， and thereby effectively enhancing recipient satisfaction.

Metastasis is an important factor for the high recurrence and mortality rates of hepatocellular carcinoma (HCC), and epithelial-mesenchymal transition (EMT) is an important mechanism of HCC metastasis. EMT is regulated by the transcription factors such as Snail, Twist, and ZEB which are mediated by a variety of signaling pathways including TGF-β, Wnt/β-catenin, and Notch. Inhibition of EMT-related molecules and signal pathways in HCC is considered as an important approach to inhibit the invasion and metastasis of HCC. Recent studies have shown that a variety of compound traditional Chinese medicine (TCM) formula or their effective constituents can inhibit the invasion and metastasis of HCC by arresting or reversing EMT in HCC. This article reviews the role and mechanism of EMT and recent studies on TCM drugs and their derived natural compounds in inhibiting the invasion and metastasis of HCC by regulating cell EMT, so as to provide a scientific basis for the TCM prevention and treatment of HCC metastasis and new ideas for HCC treatment.

ObjectiveTo clarify the perception of the work and satisfaction levels among personnel conducting unified elderly care needs assessment in Shanghai， to analyze the factors influencing their job satisfaction， and to provide references for optimizing the job satisfaction of unified elderly care needs assessment personnel in Shanghai. MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences， while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work， 92.5% of the surveyed personnel believed their work was important. Moreover， 87.1% were interested in their assessment tasks， and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction， 83.9% of the participants were satisfied with their assessment work， 78.5% considered the workload appropriate， and 74.2% found the working hours suitable. Additionally， 65.6% expressed satisfaction with the level of cooperation from the assessment subjects， while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging， respectively. Furthermore， 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation， workload， time spent on the job and institutional support related to external assistance， job suitability， teamwork， and client cooperation （P<0.05）， while motivational factors included recognition of the significance of the job， sense of achievement， interest in the job， sense of belonging， and opportunities for personal growth （P<0.05）. ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process， establish a professional team of assessment personnel， and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.
