RESUMEN
Objective@#To investigate the sleep status among primary and middle school students in Zhoushan City, Zhejiang Province, so as to provide insights into improving the sleep quality among primary and middle school students.@*Methods@#A district and a county was selected using the cluster random sampling method from Zhoushan City in October, 2019, and grades 4 to 6 primary school students, junior high school and high school students were sampled as the study subjects. Students' gender, grade, residing in schools, duration of homework and duration of extracurricular classes were collected using the questionnaires of the 2019 national program for common diseases and health risk factors surveillance and intervention program among Chinese students. According to the Plan for the Comprehensive Prevention and Control of Myopia among Children and Adolescents, daily sleep duration of 10 h and longer among primary school students, 9 h and longer among junior high school students and 8 h and longer among high school students were defined as adequate sleep, and the proportion of adequate sleep was estimated among primary and middle school students.@*Results@#Totally 3 042 students were enrolled, including 1 587 boys (52.17%) and 1 455 girls (47.83%), 996 primary school students (32.74%), 1 030 junior high school students (33.86%), 758 ordinary high school students (24.92%) and 258 vocational high school students (8.48%). The mean sleep duration was (9.23±1.10) h among primary school students, (8.09±1.05) h among junior high school students, (7.20±1.26) h among ordinary high school students and (7.97±1.03) h among vocational high school students, respectively, and the proportion of adequate sleep was 26.31% among primary school students, 22.82% among junior high school students, 22.56% among ordinary high school students and 66.67% among vocational high school students, respectively. A relatively higher proportion of adequate sleep was seen among primary school students in Grade 4 (33.63%) and with homework duration of less than 1 h (34.53%); among junior high school students in Grade 1 (37.76%), residing in schools (40.00%), studying in county schools (30.87%), with homework duration of less than 1 h (34.69%) and less than 1 h duration of extracurricular classes (33.33%); among male ordinary high school students (28.03%), and ordinary high school students in Grade 1 (28.30%), residing in schools (26.18%) and studying in district schools (25.83%); among male vocational high school students (69.06%) and vocational high school students residing in schools (73.14%).@*Conclusion@#The proportion of adequate sleep is low among primary and middle school students in Zhoushan City. The homework duration and duration of extracurricular classes are recommended to be reduced to ensure adequate sleep among primary and middle school students.
RESUMEN
Objective @#To study the epidemiological characteristics of coronavirus disease 2019 （COVID-19） in Zhoushan, so as to provide reference for improving the prevention and control capability of COVID-19.@*Methods @#All the confirmed cases of COVID-19 in Zhoushan, diagnosed according to China’s “COVID-19 diagnosis and treatment plan （fifth version） ” and reported from January 19 to February 17, 2020, were extracted from the infectious disease surveillance system. Data of general information, clinical characteristics, laboratory Results, transmission and detection routes were collected and analyzed. @*Results @#By February 17, Ten confirmed cases of COVID-19 in Zhoushan had been reported, including 7 males and 3 females. They were all adults, with an average age of （50.90±15.00） years. Five cases were discharged. The incubation period ranged from 2 to 12 days, with a median of 5 days. The first symptoms were fever （8 cases）, cough （7 cases） and muscle pain （2 cases）. Chest computed tomographic （CT） scans showed ground glass opacities in the lungs of all the cases. Six cases had Wuhan related exposure. SARS-CoV-2 was tested positive in the sputum specimens or throat swabs of all the cases and the faeces of 4 cases. The last suspicious exposure of 5 cases occurred before, and that of another 5 cases occurred after the onset of clinical symptoms in the confirmed maternal cases. Three cases were found in active consultation after clinical symptoms, and another 7 cases were found in the monitoring of close contacts.@*Conclusions @#The 10 confirmed cases of COVID-19 reported in Zhoushan are all adults, and most have Wuhan related exposure. SARS-CoV-2 can be detected in the fecal samples, but the existence of fecal-oral transmission needs more research. SARS-CoV-2 has strong infectivity, and may also have infectivity before the onset of symptoms （at the end of incubation period）. Isolation and early detection of close contacts are conducive for early case-finding.
RESUMEN
<p><b>OBJECTIVE</b>To analyze the geographic spatial patterns and risk areas of main digestive system cancers in Yiwu city.</p><p><b>METHODS</b>Newly diagnosed cases of esophageal, gastric and colorectal cancer during 2010-2014 were obtained from Yiwu Center for Disease Control and Prevention (CDC). The household registration population data in 2013 were obtained from public security bureau. Hierarchy clustering and partitioning regionalization method was used to generate geographic units. Global Moran's I was used to evaluate whether cancer incidence was significantly clustered in space, Anselin Local Moran's I was used to identify statistically significant hot spots, cold spots, and spatial outliers, and Spatial Scan Statistics was implemented to analyze the relative risk of cancers in different areas.</p><p><b>RESULTS</b>The 5-year average incidence of esophageal, gastric and colorectal cancers were 9.99/100 000, 34.01/100 000 and 31.46/100 000, respectively. Males showed significantly higher incidence than females. The incidence was heterogeneous throughout the study area. Spatial Scan analysis revealed that southern Yiwu presented a significantly higher male esophageal cancer (=1.78) and gastric cancer (=1.87) risk. The central area of Yiwu showed a significantly lower female esophageal cancer risk (=0.00) and male stomach cancer risk (=0.63) and the northern Yiwu exhibited a significantly lower female colorectal cancer risk (=0.48).</p><p><b>CONCLUSIONS</b>The incidence of main digestive tract cancers shows a heterogeneous distribution in Yiwu city.</p>
RESUMEN
Severe fever with Thrombocytopenia Syndrome (SFTS) is an emerging hemorrhagic fever disease in the rural areas of east-central China,which is caused by SFTSV-a newly discovered bunyavirus.SFTSV is most likely transmitted by tick bites but can also be transmitted within human beings.The onset of SFTS is sudden and with rapid progress,with main clinical manifestations as fever,thrombocytopenia,leucopenia and gastrointestinal and hepatorenal dysfunctions.Some patients may die from multiple organ failure,and the case fatality rate is approximately 10％.In this paper,we use the method of literature review to summarize the recent research progress of SFTS which includes the epidemic distribution characteristics,medium of transmission,host animals,transmission routes and susceptibility in the general population.
