Objective:To investigate the effects of circular RNA circ_0086376 on the expression of acne-related inflammatory factors by targeting microRNA (miR) -5195-3p.Methods:Circ_0086376-overexpressing or -interferred stable HaCaT cell lines were constructed and co-cultured with Propionibacterium acnes ( P.acne). Quantitative real-time PCR was used to detect the effect of co-culture on circ_0086376 expression, while enzyme-linked immunosorbent assay (ELISA) was performed to measure the expression of inflammatory factors in the cell culture supernatant. The overexpression or interference of circ_0086376 plasmid and lentivirus mimicking or inhibiting miR-5195-3p fragment were transfected into HaCaT cells, and ELISA was used to detect the expression of inflammatory factors in the culture supernatant of HaCaT cells after overexpression or interference of circ_0086376 cultured alone or with P.acne. The luciferase reporter assay was conducted to verify the targeting relationship between circ_0086376 and miR-5195-3p. Additionally, ELISA was used to detect the effects of overexpression/interference of circ_0086376 and mimic/inhibition of miR-5195-3p on the expression of inflammatory factors in the culture supernatant of HaCaT cells co-cultured with P.acne. Results:After co-culture with P.acne, the levels of inflammatory factors in the culture supernatant were significantly higher than those in the HaCaT cells cultured alone, including Interleukins (IL) -1β ([355.80 ± 23.20] vs. [260.50 ± 16.58] pg/ml, t = 5.79, P < 0.01), IL-6 ([38.04 ± 2.69] vs. [14.33 ± 0.75] pg/ml, t = 14.65, P < 0.01), IL-12 ([10.87 ± 0.78] vs. [6.52 ± 0.77] pg/ml, t = 6.89, P < 0.01), IL-18 ([222.60 ± 21.07] vs. [146.10 ± 9.14] pg/ml, t = 5.77, P < 0.01), and Tumor necrosis factor (TNF) -α ([50.39 ± 1.29] vs. [20.46 ± 0.83] pg/ml, t = 33.83, P < 0.01). The expression levels of IL-1β, IL-6, IL-12, IL-18 and TNF-α in the culture supernatant of HaCaT cells in the circ-empty vector + P.acne group were higher than those in the circ-empty vector overexpression group. The levels of inflammatory factors mentioned above in circ-overexpression + P.acne group were lower than those in circ-overexpression empty vector + P.acne group ( P < 0.01). The expression levels of inflammatory factors mentioned above in the culture supernatant of HaCaT cells in the interference circ-empty vector + P.acne group were higher than those in the interference circ-empty vector group. Compared with the interference circ-empty vector + P.acne group, the expression of circ in the interference circ + P.acne group was higher ( P < 0.01). Luciferase reporter assay confirmed that circ_0086376 could bind to miR-5195-3p. The expression levels of IL-1β, IL-6, IL-12, IL-18 and TNF-α in the circ-overexpression group were lower than those in the empty vector group ( P < 0.05), and the levels of these inflammatory factors in the circ-overexpression + miR mimic group were higher than those in the circ overexpression group ( P < 0.05). The expression levels of inflammatory factors in the interference circ group were higher than those in the empty vector group, levels of inflammatory factors in the circ + miR-inhibiting group were lower than those in the circ interference group ( P < 0.05) . Conclusion:Circ_0086376 can inhibit the expression of acne-related inflammatory factors by targeting and downregulating miR-5195-3p.

Objectives:To explore the trend of the burden of cardiovascular disease (CVD) in adult Chinese population attributed to high body mass index (BMI) from 1990 to 2021,identify key populations requiring for BMI control,and provide scientific evidence for developing targeted intervention strategies.Methods:Based on the Global Burden of Disease (GBD) 2021 database,we compared the age-standardized disability-adjusted life years (DALY) rates and age-standardized mortality rates of CVD attributed to high BMI for the adult population aged ≥20 years in China,globally,and in the United States,the United Kingdom,Japan,and India from 1990 to 2021.Additionally,the results were stratified by sex and age to compare the trends of disease burden in China and globally.Results:From 1990 to 2021,the average annual percentage change (AAPC) in age-standardized DALY rate and age-standardized mortality rate for CVD attributable to high BMI for the population aged ≥20 years in China was 1.08 (95％CI:1.05 to 1.11) and 1.00 (95％CI:0.96 to 1.03),respectively.Throughout the 32-year period,both rates were consistently lower than those in the United States and the global average,but higher than those in India and Japan.Meanwhile,England experienced a continuous decline,with corresponding data of-3.02 (95％CI:-3.10 to-2.96) for AAPC in age-standardized DALY rates and-3.02 (95％CI:-3.11 to-2.95) for AAPC in age-standardized mortality rates,respectively.The age-standardized DALY rate attributed to high BMI for adult males in China was consistently higher than those for females,whereas the percentage of DALY showed the opposite trend,with females surpassing males.The age-standardized DALY rates for the population aged ≥20 years attributed to high BMI in China increased continuously,and the percentage of DALY increased sharply in population aged 20-39,the level of 2021 was more than three times higher as compared to 1990.Conclusions:The increasing proportion of overweight and obese individuals in China,along with the resulting rise in the prevalence and mortality of cardiovascular diseases,has led to a continuous increase in the cardiovascular disease burden.It is therefore particularly important to implement effective public health interventions to control overweight in the young and middle-aged population to reduce the burden of cardiovascular disease in China.

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.

Objective:To explore status of nutritional knowledge, attitude and practice of tumor nursing staff and analyze the influencing factors.Methods:Using the convenient sampling method, a total of 800 nurses from Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College were selected as the research objects from January to February 2021. General data questionnaire, Nutrition Knowledge, Attitude and Practice Questionnaire for Tumor Nursing Staff and Nutrition Knowledge Acquisition Way Questionnaire for Tumor Nursing Staff were used to investigate. A total of 800 questionnaires were sent out and 797 were valid.Results:For 797 tumor nursing staff, the total score of Nutrition Knowledge, Attitude and Practice Questionnaire for Tumor Nursing Staff was (63.50±14.87) . The passing rate was 62.0% and the excellent rate was 13.8%. The results of multivariate analysis showed that professional title, educational background and department were the influencing factors of nutrition knowledge, attitude and practice of tumor nurses ( P<0.05) . Conclusions:Tumor nursing staff have positive attitudes and practice towards nutrition therapy, but their knowledge of nutrition needs to be strengthened. It is necessary to carry out nutrition-related training based on influencing factors.

MicroRNAs (miRNAs) are a class of non-coding RNA molecules that regulate gene expression after transcription and participate in various pathophysiological processes in the skin. In recent years, it has been reported that changes in miRNA expression profiles are related to some inflammatory skin diseases. For example, miR-203, miR-146a and miR-21 are upregulated in psoriatic lesions, miR-155 and miR-146a are upregulated in atopic dermatitis lesions, miR-21, miR-223, miR-142-3p and miR142-5p are upregulated in allergic contact dermatitis lesions; however, miR-146a and miR-155 are downregulated in peripheral blood of patients with systemic lupus erythematosus, and miR-223 is downregulated in dermatomyositis lesions. This review summarizes relationships of miRNAs with the occurrence and development of some inflammatory skin diseases.

In recent years, the category of atopic dermatitis (AD) has been updated in domestic and foreign guidelines, and elderly AD has been added as a subtype. The pathogenesis of elderly AD is related to heredity, skin barrier dysfunction, immune dysregulation and lifestyle. Most elderly AD patients have atypical clinical symptoms, and misdiagnosis is very common. To fully understand the pathogenesis and clinical characteristics of elderly AD, and to formulate individualized diagnosis and treatment plans based on clinical characteristics, are particularly important for improving the quality of life of patients and reducing the burden of the disease.

Objective? To compare predicted incidence of chemotherapy induced nausea and vomiting (CINV) by doctors, nurses and patients with its actual incidence. Methods? We used the prospective paired design to select 320 patients with the induced vomiting plan of medicine department at Peking Union Medical College Cancer Hospital by convenience sampling, and we allocated 72 doctors and 48 responsibility nurses for patients. The predicted chemotherapy induced nausea and vomiting scale was filled in by doctors, nurses and patients as required to understand the incidence of CINV predicted by them. After patients completed their chemotherapy, the Chinese version of MASCC antiemesis tool (MAT) was filled out by nurses to investigate the actual incidence of CINV. Results? The paired chi-square test showed that the incidence of acute and delayed CINV were 38.75% and 61.25% respectively. There was no statistical difference between the incidence of acute CINV predicted by doctors, nurses as well as patients and the actual incidence (P＞0.05). There was also no statistical difference between the incidence of delayed CINV predicted by nurses and the actual incidence (P＞0.05). Doctors and patients all underestimated the incidence of delayed CINV with a statistical difference (P＜0.05). The consistency between the incidence of acute as well as delayed CINV predicted by doctors, nurses, patients and the actual incidence was poor with Kappa value ranging from 0.02 to 0.34. A total of 54.93% to 57.77% of doctors and nurses predicted that CINV could be controlled well lower than that (about 70%) of patients with statistical differences (P＜0.05). Conclusions? There is still much improvement space for control of delayed CINV. Medical staff should take effective measures to improve the level of estimate and the level of CINV symptom management, and to improve the quality of life among patients.

Objective? To compare the evaluation result of 10 symptoms including poor appetite in cancer patients during chemotherapy from the patients and their nurses, in order to improve the assessment and judgment ability of the responsible nurses on the symptoms of patients undergoing chemotherapy through the analysis of the result. Methods? The study was performed in the chemotherapy unit of a cancer ClassⅢGrade A hospital in Beijing. By convenience sampling, a total of 192 patients undergoing chemotherapy from October 2017 to January 2018 and the nurses (n=16) who were primarily responsible for their care were selected as participants. Symptom assessments were completed by the use of the Edmonton Symptom Assessment System (ESAS). Results? Patients and nurses showed poor agreement in Depression, Anxiety and Shortness of breath (ICC＜ 0.4) and moderate agreement (0.4 ≤ICC＜ 0.75) in other symptoms. Wilcoxon signed rank test was used to compare the results of symptom assessment between patients and responsible nurses. Among the 10 entries in ESAS, there was no statistical difference between the results in poor quality of life (Z=-1.627, P=0.104), however, there were statistical differences in all the rest 9 entries (P＜0.05) among which the nurses scored higher than the patients in the entry of anxiety and depression. Conclusions? Responsible nurses' perception on physical symptoms was better than that of psychological symptoms, and there was overestimation and underestimation in the severity of symptoms. It is necessary for the nurses to teach the patients how to use standard assessment tools and through health education, raise the patients' awareness of reporting their symptoms.
