Objective To survey the causes and pathogenic factors of an outbreak of acute gastroenteritis occurred in a school in Beijing in 2021.Methods The clinical manifestations of the cases and their time,regional and population distribution were described with descriptive epidemiological methods.Case-control study,retrospective cohort study and logistic regression analysis were used to find out the suspected exposed meals and suspected pathogenic food.A field hygienic survey was carried out.Samples from the cases,food processing tools and environment were collected for the PCR detection of norovirus.Results A total of 92 cases were detected,and their main clinical symptom was vomiting(84.78％),followed by nausea(58.70％),diarrhea(31.52％),abdominal pain(29.35％)and fever(25.00％).The results of the field epidemiological survey demonstrated that the breakfast on April 1st was the suspected exposed meal,and kernel cucumber was the suspected pathogenic food,which might be contaminated by a kitchen worker with norovirus infection during the preparation in the canteen.23 strains of norovirus GⅡ were detected from 72 stool samples/anal swabs.Conclusion This is an outbreak of foodborne acute gastroenteritis caused by norovirus GⅡ in the school.The kernel cucumber contaminated by norovirus is the main infection source of this outbreak of foodborne illness.
沙眼衣原体(Chlamydiatracho matis,Ct)是一种常见的专性细胞内寄生微生物,他能够引起女性宫颈炎、输卵管炎、盆腔炎、子宫内膜炎等多种疾病,是最为常见的性传播病原体之一,迄今也没有特异性Ct疫苗可以预防其传播.目前关于Ct的致病机制还没有完全研究明白,但由于分子生物学,生物信息学,生物物理学的迅速发展,现在已经克隆并验证了包括热休克蛋白、主要外膜蛋白、衣原体分泌蛋白、质粒蛋白和一些新发现的可能的毒力蛋白.本研究对其毒力因子的进展进行研究,为预防和控制Ct所致的疾病提供参考.
Objective To explore the mediating effect of hope level on relationship between social support and loneliness in tumor patients．Methods Two hundred and forty-one tumor patients were conveniently selected as the research subjects.General information questionnaire,Herth Hope Scale,Perceived Social Support Scale and Cancer Loneliness Scale were used for a questionnaire survey.The mediating effect of hope level on relationship between social support and loneliness in the tumor patients were analyzed．Results The total scores of hope level,perceived social support and loneliness in the tumor patients were（32.29±6.92）,（53.17±13.71） and （16.94±6.67）,respectively.The level of hope was positively correlated with perceived social support,but negatively correlated with cancer loneliness.Perceived social support was negatively associated with cancer loneliness.Social support not only directly affected loneliness of the tumor patients,but also indirectly affected loneliness through the mediating effect of hope.The intermediary effect accounted for 49.92%of the total effect．Conclusion Hope level is an intermediary variable between social support and loneliness in the tumor patients.Medical professionals should take targeted intervention measures and improve the tumor patients’social support and hope level so as to reduce their loneliness.
目的 探讨复发性流产(recurrent spontaneous abortion,RSA)女性自我认同感,分析其与家庭支持、情绪内疚感间的相关性,为临床针对性干预提供参考.方法 选取2017年4月—2022年4月在河南中医药大学第一附属医院接受治疗的274例RSA女性,问卷调查一般资料,量表评估自我认同感、家庭支持、情绪内疚感相关评分,利用Pearson法分析三者间的相关性,进一步采用依次检验法检验家庭支持在自我认同感与情绪内疚感间的中介效应.结果 274例RSA女性自我认同感评分(49.79±6.78)分,其中＜46分者占63.50％,≥46分者占36.50％;家庭支持评分(10.49±2.11)分,低水平者占10.95％,中等水平者占30.29％,高水平者占58.76％;情绪内疚感评分(16.27±2.10)分,＜15分者占40.51％,≥15分者占59.49％;Pearson法相关性得知,自我认同感评分与家庭支持评分呈正相关(r=0.532,P＜0.001)、与情绪内疚感评分呈负相关(r=-0.468,P＜0.001);家庭支持评分与情绪内疚感评分呈负相关(r=-0.512,P＜0.001);家庭支持在自我认同感与情绪内疚感之间的中介效应占总效应的比值为76.84％.结论 多数RSA女性自我认同感低,自我认同感、家庭支持、情绪内疚感三者间具有一定相关性,且自我认同感不仅能直接减轻RSA女性内疚心理,还可通过家庭支持的中介效应而对情绪内疚感产生间接调节作用,需重视家庭支持这一变量在自我认同感、情绪内疚感间的中介效应.
Objective To investigate the current status of emotional intelligence, depression, anxiety and stress among residents in Hunan, and to explore the relationship of emotional intelligence with depression, anxiety and stress. Methods A stratified cluster sampling method was used to select 1,965 residents from 5 regions in Hunan Province for a questionnaire survey. Difference test, Pearson correlation analysis and multiple linear regression were performed for statistical analysis. Results The scores of emotional intelligence, depression, anxiety and stress were（119.93±20.66）,（11±4.25）,（11.26±4.17） and（12.06±4.22）, respectively. The detection rates of depression and anxiety were 52.16% and 80%, respectively. Pearson correlation analysis displayed that emotional intelligence was negatively correlated with stress, depression and anxiety（all P＜0.01）, while stress was positively correlated with depression and anxiety（all P＜0.01）. Multiple linear regression analysis revealed that gender, average annual household income, stress and depression were factors affecting emotional intelligence of Hunan residents. Conclusion The level of emotional intelligence in Hunan residents is affected by many factors. The higher the level of emotional intelligence, the lower the levels of depression, anxiety and stress. Science popularization workers should take targeted intervention measures to accurately carry out science popularization of emotional intelligence among residents. Relevant departments should speed up the establishment of social psychological counseling mechanism, train mental health service personnel, improve the psychological service system, and actively promote the popularization of mental health.
