Objective: To analyze the research status, hotspots and frontier progress of hypertension in children in English and Chinese literature, so as to provide reference for the early prevention of hypertension in children. Methods: The Web of Science core collection database and CNKI database were searched to collect the literature related to the study of hypertension in children from 2000 to 2021, and the CiteSpace 5.8.R3 and VOSviewer 1.6.18 visualization tools were used to analyze the literature characteristics including publications, authors, regions, institutional cooperation, research hotspots and frontiers. Results: A total of 22 687 English studies and 4 440 Chinese studies were finally included. According to the analysis results, the number of articles published on hypertension in children was on the rise. The published English articles were mainly University of Toronto and University of Colorado. The main publishing institution of Chinese articles was the First Affiliated Hospital of Peking University. The United States and China took the lead in the number of core journals published in the field of hypertension in children, the United States ranked first in terms of the influence of publications. Keyword co occurrence analysis showed that the high frequency keywords in the English literature included prevalence, risk, obesity, risk factor, body mass index, insulin resistance, overweight, metabolic syndrome, cardiovascular disease and mortality. Chinese high frequency keywords in the literature include obesity, risk factors, adiposis, influencing factors, overweight, prevalence, diabetes, treatment, health education and body mass index. The analysis of keywords showed that 25 burst terms were obtained separately in English and Chinese literature. Conclusion In recent years, the research interest on hypertension in children continues to grow and keeps updated, with the research scope expanding significantly, regarding obesity, diabetes and cardiovascular diseases.

OBJECTIVE: To determine the mass scores of naringin and neohesperidin in Fructus aurantii and Citrus chang-shan-huyou with their processed products and evaluate the quality of Fructus aurantii and Citrus changshan-huyou with their pro-cessed products. METHODS:According to the requirements of Chinese Pharmacopoeia(2010 edition)and Zhejiang Province Tradi-tional Chinese Medicine Preparation Standards (2005 edition),the moisture and ash of F. aurantii and C. changshan-huyou with their processed products were detected. And the contents of naringin and neohesperidin were determined. The ZORBAX SB-C18 column was used with the mobile phase of acetonitrile-water(20∶80,V/V)at the flow rate of 1.0 ml/min. The detection wave-length was set at 283 nm,and the column temperature was 40℃.The samples size was 10μl. RESULTS:The moisture of F. au-rantii and C. changshan-huyou was decreased after processing with no obvious change for ash. The contents of naringin and neohes-peridin were decreased,significantly for F. aurantii,and all consistent with the requirements of Chinese Pharmacopoeia(2010 edi-tion)except F. aurantii. The linear range was 0.028 45-0.284 5μg(r=0.999 7)for naringin and 0.085 9-0.858 6μg(r=0.999 6)for neohesperidin;the RSDs of precision,stability and reproducibility tests were no more than 1.36% and the average recovery was re-spectively 96.45%-100.43%(RSD=1.45%,n=6) and 98.36%-102.00%(RSD=1.26%,n=6). CONCLUSIONS: There was no significant difference in the inspection and determination re-sults in F. aurantii and C. changshan-huyou. It is suggested to adjust the limitation of content determination in the Chinese Pharmacopoeia(2010 edition)and processed standards.

Purpose: From the perspective of positive psychology, our study aimed to explore depressive symptomsand psychological well-being among Chinese nurses, as well as analyze the impacts of characterstrengths, self-efficacy and social support on the mental health of nurses. Methods: A cross-sectional and descriptive design using five self-reported questionnaires was used toinvestigate a cohort of 4238 nurses during 2018. A structural equation modeling analysis was used toverify a hypothetical model linking character strengths, self-efficacy, social support, depressive symptoms,and psychological well-being. Results: The prevalence of depression among this cohort of Chinese nurses was 58.1%. The mean scoresfor caring, inquisitiveness, and self-control were 19.93 (SD = 2.82), 15.94 (SD = 3.00), and 16.34(SD = 2.95), respectively. The hypothesized model was a good fit of the data (x2/df = 1.77, p = .183, rootmean square error of approximation = 0.04, goodness of fit index = 1.00, comparative fit index = 1.00,TuckereLewis index = 1.00). Except for the path from self-control to depression, the other hypotheticalpaths investigated were statistically significant. Conclusion Character strengths were directly and positively associated with psychological well-being.Inquisitiveness was the strongest direct protective factor for depression. In addition, characterstrengths indirectly alleviated depression and increased psychological well-being through mediatingvariables of social support and self-efficacy. This study should alert nurse managers that more attentionshould be paid to the character strengths and mental health of nurses. This study provides evidence forinterventions based on character strengths as a management strategy to support the mental health ofnurses.

Objective:To investigate the diagnostic value of immunoglobulin M (IgM) and immunoglobulin G(IgG) antibodies to 2019 Novel Coronavirus (2019-nCoV) in 2019-nCoV infection.Methods:This is a retrospective study. Serum samples were collected from 284 patients including outpatients and inpatients in the Renmin Hospital of Wuhan University from January 20 to February 17 in 2020. Among them 205 cases were 2019-nCoV infected patients, including 186 cases confirmed with nucleic acid test and 19 cases diagnosed by clinical symptoms and CT characteristics according to "the New Coronavirus Pneumonia Control Protocol (5th edition)" . A total of 79 subjects with other diseases but negative to 2019-nCoV infection were recruited as control group. Serum IgM and IgG antibodies to 2019-nCoV were measured with fully automated immunoassay technology for all subjects. Statistical significance between 2019-nCoV antibodies test and 2019-nCoV nucleic acid test was determined using the χ 2 tests. Results:The sensitivity of serum IgM and IgG antibodies to 2019-nCoV were 70.24%(144/205) and 96.10%(197/205) respectively and the specificity were 96.20%(76/79) and 92.41%(73/79) respectively. The positive and negative predictive values of 2019-nCoV antibodies were 95.63%(197/206) and 91.03% (71/78) respectively, and the positive and negative predictive values of 2019-nCoV nucleic acid test were 100%(186/186) and 80.61%(79/98) respectively. The total coincidence rate of diagnosing 2019-nCoV infection between antibody tests and nucleic acid test for 2019-nCoV were 88.03%(250/284).Conclusion:Joint detection of serum IgM and IgG antibodies to 2019-nCoV is an effective screening and diagnostic indicators for 2019-nCoV infection, and an effective complement to the false negative results to nucleic acid test.

OBJECTIVES: This study examined the associations between adverse childhood experiences (ACEs) and diabetes within a social-ecological framework, incorporating personal and environmental unfavorable conditions during childhood from family, school, and community contexts. METHODS: Data were obtained from the China Health and Retirement Longitudinal Study (2014 life history survey and 2015 survey), including 9,179 participants aged ≥45 years. ACEs were collected through self-report questionnaires, and participants were categorized based on the number of distinct ACEs experienced (0, 1, 2, 3, or ≥4 ACEs). Diabetes was defined by biomarkers, self-reported diagnosis, and treatment status. Logistic regression was conducted to explore the associations between ACEs and diabetes. Subgroup analyses were conducted by gender, age, and obesity status. RESULTS: Compared with participants without ACEs, those exposed to any ACE (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.01 to 1.40), 3 ACEs (OR, 1.32; 95% CI, 1.07 to 1.62) and ≥4 ACEs (OR, 1.29; 95% CI, 1.07 to 1.56) had an increased risk of diabetes. For each additional ACE, the risk of diabetes increased by about 5%. Regarding the source of ACEs, those originating from the family (OR, 1.23; 95% CI, 1.08 to 1.41) were associated with diabetes. In terms of specific ACE types, family members with substance abuse (OR, 1.23; 95% CI, 1.01 to 1.52), emotional abuse (OR, 1.28; 95% CI, 1.12 to 1.46), and poor parental relationship (OR, 1.25; 95% CI, 1.09 to 1.43) were associated with diabetes. CONCLUSIONS ACEs, particularly those originating from the family, were associated with diabetes. Interventions aimed at preventing and mitigating ACEs are essential for the early prevention of diabetes.
