Objective To analyze the incidence of malignant tumor in Shaoxing of Zhejiang Province in 2012.Methods Descriptive analysis was carried out based on our chronic disease monitoring information management system.Age-standardized incidence was calculated according to Chinese standard population in 1982 and the Segi's world population.Results The crude incidence of malignant tumor was 291.34/100 000,age-standardized rate by Chinese standard population (ASR China) and by world population was 137.29/100 000 or 176.72/100 000,respectively.The cumulative rate of the 0-74 years old group was 20.27％ and the cut rate of the 35-64 years old group was 301.49/100 000.Male crude incidence of cancer and ASR China were 330.46/100 000 and 149.28/100 000,respectively; for female,the figure was 251.93/ 100 000 and 124.79/100 000,respectively.The crude incidence and ASR China were 364.85/100 000 and 171.77/100 000 in urban area residents,and 277.86/100 000 and 130.93/100 000 for those living in rural areas.Age-specific incidence of the 0-29 years old group remained low,although the incidence was increased after 30 years old and reached the peak in the 80-84 years old group.The most common malignancy were lung cancer,gastric cancer,colorectal cancer,liver cancer,breast cancer,thyroid cancer,esophageal cancer,pancreatic cancer,cervical cancer and leukemia (76.77％).Conclusions Lung cancer,gastrointestinal cancer and female reproductive system cancer were most common malignancy in Shaoxing of Zhejiang Province in 2012.The incidence of thyroid cancer,leukemia and brain tumor is significantly increased over the past few years,which may need effective control and prevention strategies.

Objective To analyze the detection rate of thyroid cancer from 2009 to 2013 in Shaoxing of Zhejiang province and its time trend.Methods The data of thvroid cancer in Shaoxing from 2009 to 2013 was collected to calculate the detection rate,age adjusted detection rate and percentage change of incidence,and the annual percentage change (APC) of incidence was estimated by linear regression based on the logarithm of the incidence rates observed.Results lDuring 2009-2013,a total of 3 290 new cases were diagnosed as thyroid cancer with the sex ratio of male to female being 1 ∶ 3.69.The detection rate of thyroid cancer was 14.98/100 000 (male 6.39/100 000,female 23.59/100 000),with age-standardized detection rate by Chinese standard population (ASR China)9.13/100 000(male 3.94/100 000,female 14.31/100 000),and age-standardized detection rate by world standard population(ASR worll) 10.39/100 000(male 4.47/100 000,female 16.32/100 000).The detection rate of thyroid cancer increased from 7.26/100 000 in 2009 to 27.26/100 000 (APC =39.65％,P＜0.05),with the detection rate among males increasing from 2.42/100 000 to 12.65/100 000(APC =48.44％,P＜0.05),and the detection rate among female increasing from 12.15/100 000 to 41.96/100 000(APC =37.58c％,P＜0.05).In Shaoxing,most of the new thyroid cancer cases were from 25 to 59 years old,and the highest incidence happened in the group of 50-54 years.For each age group,the detection rate in female was almost over two-folls higher than the incidence in male.Conclusion The detection rate of thyroid cancer was increased year by year from 2009 to 2013 in Shaoxing,especially among the young and middle-aged women.The corresponding measures must be taken to control the risk factors of thyroid cancer.

Objective To analyze the detection rate of lung cancer during 2009-2013 in Shaoxing of Zhejiang province and its time trend. Methods The data of lung cancer in Shaoxing from 2009 to 2013 with a total coverage population of 21 970 825 person-year (male 10 993 657 person-year, female 10 977 168 person-year), was collected to calculate the detection rate, age adjusted detection rate, percentage change of incidence (PC), etc. The annual percentage change (APC) of incidence was estimated by linear regression based on the logarithm of the incidence rates observed. Results During 2009-2013, a total of 9 973 new cases were diagnosed as lung cancer with the sex ratio of male to female being 2.44∶1. The detection rate of lung cancer was 45.39/100 000 (male 64.35/100 000, female 26.41/100 000), age-standardized detection rate by Chinese standard population (ASR China) was 20.09/100 000 (male 28.37/100 000, female 11.66/100 000), age-standardized detection rate by world standard population (ASR world) was 27.26/100 000 (male 37.83/100 000, female 15.73/100 000). The cumulative rate and truncated rate of those aged 0-74 and 35-64 were 3.40% (male 4.80%, female 1.91%) and 39.90/100 000 (male 54.44/100 000, female 24.81/100 000).

Objective To understand the prevalence of negative life events and its association with depressive, anxiety symptoms and dissatisfaction of school life among middle school students in Shaoxing, and to provide scientific evidence for further interventions. Methods A total number of 3 197 students (including 1 134 urban and 2 063 town adolescents) were recruited from 2 middle schools in Shaoxing, their average age was (13.73 ± 1.03) years. The Multidimensional Life Events Rating Questionnaire for Middle School Students (MLERQ), Depression Self-rating Scale for Children (DSRSC) and Screening for Child Anxiety Related Emotional Disorders (SCARED) were used to assess the mental health status, while the school life satisfaction was evaluated by the School Life Satisfaction Rating Questionnaire for Adolescents (SLSRQA), and the data were analyzed by descriptive statistics and multivariate logistic regression models. Results The prevalence of the negative life events was 84.9%, unsatisfactory examination performance (48.6%), unreached the teacher's expectation (46.2%), parental chatter (41.4%), unbalanced learning (37.9%), and getting parents scold (27.6%) constituted the main negative life events. The prevalence of depressive symptom, anxiety symptom, and dissatisfaction of school life were significantly higher among middle school students living with negative life events (41.1%, 22.6%, 26.0%) than those without negative life events (20.9%, 3.5%, 16.5%), (?2=71.33, 94.78, 19.83, P<0.001). The prevalence of the psychosomatic health involvement significantly increased with the increase of the number of the dimensions and events (P<0.001). The multivariate logistic regression showed that negative life events were the risk factors of depression, anxiety and dissatisfaction of school life. Their OR values were 2.483 (1.951-3.160), 7.245 (4.411-11.899) and 1.733 (1.325-2.267), respectively. The risk of occurring mental symptoms among children with the number of dimensions≥4 and/or the number of events≥12 was two times higher than those of children without such increase in numbers of dimensions and events. Conclusion The status of negative life events is serious among middle school students in Shaoxing. There are statistical associations between negative life events and mental symptoms.

The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022 (APC=-11.101%, t=-9.930, P<0.001), and the incidence of HFRS peaked from May to June and from November to January of the next year. A higher incidence of HFRS was seen in men than in women (1.76/105 vs. 0.68/105; χ2=201.361, P<0.001). There were 714 HFRS cases at ages of 30 to 59 years (69.86%), and farmers were the predominant occupation (78.18%). The three counties with the largest number of HFRS cases included Zhuji (366 cases), Xinchang (263 cases) and Shengzhou (134 cases). The incidence of HFRS was lower in urban districts (Yuecheng, Keqiao and Shangyu) than in counties (Zhuji, Shengzhou and Xinchang) (0.58/105 vs. 1.96/105; χ2=326.880, P<0.001). Conclusion The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022, and the incidence was high in late spring, early summer and winter. The HFRS cases were mainly males, young and middle-aged people, and farmers, and predominantly distributed in counties. Targeted control measures are needed.

Objective: To investigate the epidemiological and etiological characteristics of viral diarrhea among children under 5 years of age in Shaoxing City, Zhejiang Province, so as to provide insights into management of viral diarrhea. Methods: The surveillance data on viral diarrhea among children under 5 years of age in Shaoxing City from 2019 to 2022 were collected, including demographics and stool testing results. The epidemiological and etiological characteristics of viral diarrhea were analyzed using a descriptive epidemiological method. Results: A total of 763 diarrheal children under 5 years of age were reported in Shaoxing City from 2019 to 2022, and 236 children were tested positive for virus (30.93%). The detection of virus was 49.01%, 31.61%, 20.43% and 21.89% from 2019 to 2022, which appeared an overall tendency towards a decline (P<0.05). The incidence of viral diarrhea peaked from November to March of the next year and from May to July, and the detection of virus was lower among children with diarrhea living in urban areas (Yuecheng District, Keqiao District and Shangyu District) than among those in suburb areas (Zhuji City, Shengzhou City and Xinchang County) (30.22% vs. 52.00%, P<0.05). There were 206 children tested positive for a single virus, and the detection rates of rotavirus (RV), enteric adenovirus (EAdV), norovirus (NoV), and sapovirus (SaV) were 9.57%, 8.91%, 8.39%, and 0.13%, respectively. There were 25 children with virus co-infections, and the positive rates of EAdV and NoV, RV and EAdV and RV and NoV co-infections were 1.31%, 1.18% and 0.79%, respectively. There were 5 children with triple infections of RV, EAdV and NoV (0.66%). The highest detection of EAdV was seen in April, the highest detection of RV and NoV was seen in January, while SaV was only detected in April. Conclusion The incidence of viral diarrhea among children under 5 years of age peaked in winter and spring in Shaoxing City from 2019 to 2022, and the cases predominantly occurred in urban areas.
