Objective To improve imaging diagnosis of Wegener granulomatosis.Methods Ten cases with Wegener granulomatosis were collected and their imaging findings were analyzed retrospectively.Results Eight cases presented sinusitis. CT showed mucosa thicken, accompanied with the destruction of middle-line structure in 3 cases and orbit mass in 2 cases. Seven cases involved lungs. Pulmonary imaging were complicated, showing multiple nodules or masses in 3 cases and multiple variable signs in the others. One case showed left upper bronchus obstruction. Conclusion Imaging of Wegener granulomatosis is complicated. Wegener granulomatosis should be diagnosed accompanied with clinical and pathologic findings.

Objective : To explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province, so as to provide scientific evidence for the prevention and control of hypertension. Methods: Data were collected from 10 national surveillance sites in Zhejiang Province in the 2018 China Chronic Disease and Risk Factors Surveillance. The multivariate logistic regression model was used to explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province. Results : Among 5 908 people included, 2 641 were males, accounting for 50.38%; and 3 267 were females, accounting for 49.62%. There were 2 721 cases of hypertension ( 28.54% ). The number of the cases with no, light and excessive alcohol consumption was 3 945, 1 117 and 846, accounting for 66.28%, 23.65% and 10.07%, respectively, after complex sampling weighting. The results of the multivariate logistic regression model showed that compared with those with no alcohol consumption, the adults with excessive alcohol consumption had higher risk of hypertension ( OR=2.126, 95%CI: 1.649-2.741 ); men with light ( OR=1.875, 95%CI: 1.075-3.270 ) and excessive alcohol consumption ( OR=2.752, 95%CI: 2.021-3.748 ) had higher risk of hypertension; the 18-<45-year-old adults with light ( OR=2.441, 95%CI: 1.171-5.087 ) and excessive alcohol consumption ( OR=3.368, 95%CI: 1.609-7.049 ), and the ≥60-year-old adults with excessive alcohol consumption ( OR=1.632, 95%CI: 1.174-2.269 ) had higher risk of hypertension. Conclusions Light and excessive alcohol consumption are associated with hypertension in Zhejiang adults. The association is stronger between excessive alcohol consumption and hypertension than between light alcohol consumption and hypertension.

Objective: To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension. Methods: Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model. Results: Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years. Conclusions Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.

Objective:To analyze the epidemiological patterns of comorbidity of anxiety symptoms and depression symptoms among middle and high school students in Zhejiang Province and to provide evidence for making strategy and evaluation of intervention.Methods:Through a multi-stage sampling design, 28 043 students from 376 schools in 30 counties/districts were recruited and surveyed using anonymous self-administered questionnaires in classrooms under the supervision of trained staff between April and June 2022. Anxiety symptoms were assessed using generalized Anxiety Disorders 7-Item Scale, and depression symptoms were assessed using Patient Health Questionnaire 9-Item Depression Scale. A total of 27 004 students were included in the final analysis.Results:The overall prevalence of comorbidity of anxiety symptoms and depression symptoms was 11.54% (95% CI: 10.90%-12.19%), higher among girls (15.42%, 95% CI: 14.47%- 16.38%) than boys (8.05%, 95% CI: 7.43%-8.67%) ( P<0.001), higher among students living in rural areas (12.35%, 95% CI: 11.49%-13.22%) than those in urban areas (10.06%, 95% CI: 9.27%-10.86%) ( P<0.001). The prevalence of comorbidity of students attending middle school, academic high school, and vocational high school was 11.73% (95% CI: 10.82%-12.64%), 12.49% (95% CI: 11.20%- 13.79%), and 9.98% (95% CI: 8.68%-11.27%), respectively ( P=0.025). The prevalence of comorbidity was higher among students in divorced/widow/separated families (16.64%, 95% CI: 14.86%-18.43%) than those in intact families (10.82%, 95% CI: 10.14%-11.50%) ( P<0.001). The wealthier the families, the lower the prevalence of comorbidity ( P<0.001). The prevalence of comorbidity was higher among cigarettes smokers in the past 30 days (21.70%,95% CI: 18.24%- 25.16%) than non-smokers (11.13%, 95% CI: 10.51%-11.76%), higher among alcohol drinkers in the past 30 days (19.36%, 95% CI: 17.58%-21.14%) than non-drinkers (10.05%, 95% CI: 9.43%- 10.68%), higher among students engaging in physical fight in the past 12 months (18.42%, 95% CI: 16.75%-20.09%) than those without physical fight (10.45%, 95% CI: 9.81%-11.10%). The more frequently students engaged in physical exercise, the lower the prevalence of comorbidity ( P<0.001). The poorer the academic performance self-reported, the higher the prevalence of comorbidity ( P<0.001). Conclusion:More than one-tenth of middle and high school students in Zhejiang Province have comorbidity of anxiety symptoms and depression symptoms, and more attention should be paid to adolescent mental health.

Objective:To understand the epidemiological characteristics of metabolic syndrome(MetS) among adult residents in Zhejiang Province and compare three diagnostic criteria in adult residents.Methods:In this cross-sectisnal study participants were randomly chosen using multi-stage stratified cluster sampling method from 10 national chronic disease risk factor monitoring sites in Zhejiang Province of the 2018 China Chronic Disease and Risk Factors Surveillance Project. Demographics and information on chronic disease prevalence were obtained through questionnaire, physical measurements, and laboratory. After complex weighting of the data, an analysis and comparison of the prevalence of MetS under different diagnostic criteria among adult residents in Zhejiang Province was conducted.Results:A total of 5 369 adult residents were included, 2 411 males and 2 958 females. The prevalence of MetS using JIS, CDS and IDF diagnostic criteria was 33.62%, 25.32%, and 24.25%, respectively. The consistency rate between IDF and JIS was the highest(89.11%) and the Kappa value was 0.768( P<0.001). The consistency rate between IDF and CDS diagnostic criteria was 84.53%, and the Kappa value was 0.631( P<0.001). The consistency rate between JIS and CDS was the lowest(83.17%), and the Kappa value was 0.621( P<0.001). Under CDS diagnostic criteria, the prevalence of MetS was associated to gender, marital status, smoking and drinking. Conclusion:The prevalence of MetS is at a relatively high level among adult residents in Zhejiang province. The consistency between IDF and JIS diagnostic criteria is the highest. Screening for MetS should be strengthened to detect high-risk individuals early, reduce the risk of cardiovascular and cerebrovascular diseases and diabetes, and improve the quality of life of residents.
