Since the emergence in 1980s,community-associated methicillin-resistant Staphylococcus Aurues (CA-MRSA) has caught great attention of the researchers and clinical practitioners all over the world. In recent scientific papers,people found that CA-MRSA's capability to adapt itself to the hostile environment and to colonize is a kind of important virulence factor. A newly unveiled gene,designated arginine catabolic mobile element (ACME),in USA300 stains contributes much to this sort of ability. The arginine deiminase encoded by ACME plays an important role in colonization.

Objective To retrospectively analyze the results of neonatal diseases screening in Yichang from 2017 to 2019, understand the incidence and recall of the diseases, and explore the management mode of neonatal disease screening suitable for this region. Methods The subjects were newborns who were delivered in Yichang midwifery institutions from 2017 to 2019 and were screened for neonatal diseases. Heel blood of the newborns was collected for the screening of neonatal diseases, including congenital hypothyroidism (CH), phenylketonuria (PKU), G6PD deficiency, congenital adrenal hyperplasia (CAH) and thalassemia. Those newborns with positive initial screening were recalled for reexamination and confirmation. The recall rates of different diseases were compared by Chi-square test. Results There were 85 891 live births in Yichang area from 2017 to 2019, and 84 063 cases were screened for neonatal diseases, with a screening rate of 97.87%. A total of 6 043 cases were positive in the initial screening, of which 5,047 cases were recalled, with a recall rate of 83.52%. The recall rates of the traditional two diseases (CH and PKU) and the new three diseases (CAH, G6PD deficiency and thalassemia) were significantly different ( χ²= 197.93, P＜0.01). A total of 501 cases were diagnosed. The incidence rate of CH was 1/1,911, the incidence rate of PKU was 1/12 009, the incidence rate of CAH was 1/28 021, the incidence rate of G6PD deficiency was 1/1 121, and the incidence rate of thalassemia was 1/226. Conclusions The neonatal disease screening rate increased year by year in Yichang, but the recall rate of suspicious positive initial screenings decreased. It is necessary to explore a more suitable management mode for the five neonatal disease screenings in this region, improve the recall rate of children with positive screening, reduce the incidence of disabled children, and improve the quality of the birth population.

Objective:To learn about the status quo and hotspots in the field of health policy research under the concept of One Health.Methods:The Web of Science Core Collection (WoS) database and China National Knowledge Infrastructure (CNKI) database from 2001 to 2020 were searched for publications in the field of health policy research under the concept of One Health. A total of 3 515 publications in English and 42 in Chinese were included, CiteSpace 5.6.R3 software was used to analyze the number of publications, countries, institutions, authors, and keywords, and to draw visual maps.Results:The number of publications in WoS database was 52 in 2001 and 500 in 2020, with an overall upward trend in the number of publications; the first relevant publication in CNKI database was published in 2009, and the number of publications increased to 13 by 2020, but the total number was still low (42). Among the countries, the USA had the highest number of publications (1 385), total citations (48 780) and highly cited (≥10 citations) publications (671). Switzerland had the highest citations per publication (89.72). China ranked 5th in the number of publications (160) and 8th in total citations (4 643) and citations per publication (29.02), with fewer highly cited publications (82). The English author partnership had a large collaborative team led by Chris Degeling at the University of Sydney; the Chinese author partnership had a large research team led by Lu Jiahai at the School of Public Health, Sun Yat-sen University. In terms of country cooperation, French node had the largest centrality (0.30), the centrality of Chinese nodes was 0.01. Emerging infectious diseases, zoonose, and antibiotic resistance were high-frequency keywords in the English publications, while COVID-19, zoonose, antibiotic resistance, and food safety were high-frequency keywords in the Chinese publications.Conclusions:From 2001 to 2020, the overall trend of the number of publications in health policy research under the concept of One Health worldwide is on the rise. Emerging infectious diseases, zoonose, antibiotic resistance, and food safety are the current research hotspots in this field.
