ABSTRACT
BACKGROUNDS@#Cancer is one of the main causes of death worldwide, seriously threatening human health and life expectancy. We aimed to analyze the cancer incidence and mortality rates during 2016 in Zhejiang Province, Southeast China.@*METHODS@#Data were collected from 14 population-based cancer registries across Zhejiang Province of China. Cancer incidence and mortality rates stratified by sex and region were analyzed. The crude rate, age-standardized rate, age-specific and region-specific rate, and cumulative rate were calculated. The proportions of 10 common cancers in different groups and the incidence and mortality rates of the top five cancers in different age groups were also calculated. The Chinese national census of 2000 and the world Segi population was used for calculating the age-standardized incidence and mortality rates.@*RESULTS@#The 14 cancer registries covered a population of 14,250,844 individuals, accounting for 29.13% of the population of Zhejiang Province. The total reported cancer cases and deaths were 55,835 and 27,013, respectively. The proportion of morphological verification (MV%) was 78.95% of the population, and percentage of incident cases identified through death certificates only (DCO%) was 1.23% with a mortality-to-incidence ratio (M/I ratio) of 0.48. The crude incidence rate in Zhejiang cancer registration areas was 391.80/105; the age-standardized incidence rate of the Chinese standard population (ASIRC) and the age-standardized incidence rate of the world standard population (ASIRW) were 229.76/105 and 220.96/105, respectively. The incidence rate in men was higher than that in women. The incidence rate increased rapidly after 45 years of age and peaked in individuals aged 80 to 84 years. The top 10 incidence rates of cancers were lung cancer, female breast cancer, thyroid cancer, colorectal cancer, stomach cancer, liver cancer, prostate cancer, cervical cancer, esophageal cancer, and pancreatic cancer (from highest to lowest). The crude mortality rate in Zhejiang cancer registration areas was 189.55/105; the age-standardized mortality rate of the Chinese standard population (ASMRC) and the age-standardized mortality rate of the world standard population (ASMRW) were 94.46/105 and 93.42/105, respectively. The mortality rate in men was higher than that in women, and the male population in rural areas was higher than that in urban areas. The cancer mortality rate increased rapidly after 50 years of age and peaked in individuals aged 85+ years. The top 10 mortality rates of cancers were lung cancer, liver cancer, stomach cancer, colorectal cancer, pancreatic cancer, esophageal cancer, female breast cancer, prostate cancer, lymphoma, and leukemia (from highest to lowest).@*CONCLUSIONS@#Lung cancer, female breast cancer, thyroid cancer, colorectal cancer, prostate cancer, liver cancer, and stomach cancer were the most common cancers in Zhejiang Province. Effective prevention and control measures should be established after considering the different characteristics of cancers in urban and rural areas.

ABSTRACT
Objective To analyze the health life expectancy (HALE) of the residents aged 15 years and above in Zhejiang Province and to evaluate the health level among adults. Methods The study was based the mortality data collected from Zhejiang Chronic Disease Surveillance Information and Management System, and the mortality rates were from the Under-Reporting Survey and the sample data in Zhejiang from the 5th National Health Service Survey in 2013. A Sullivan' s method was used to calculate the HALE. Results The life expectancy and self-evaluated HALE were 63.62 years, 55.80 years, respectively, and the difference was 7.82 years (61.49 years VS 55.13 years in males and 66.10 years VS 56.57 years in females) . The self-evaluated HALE 55.89 years in urban and 55.54 years in rural residents aged 15 years and above. The proportion of self-evaluated HALE in the total life expectancy was 87.70%, and it decreased with age, and the proportion has dropped to 67.31% in ≥65 age group. Life expectancy without chronic morbidity was 46.68 years (46.35 years in males and 47.01 years in females; 44.03 years in urban and 47.15 years in rural areas) among residents aged 15 years and above, and the proportion of self-evaluated HALE without chronic morbidity in the total life expectancy without chronic morbidity was 73.37%. Conclusion In general the proportion of self-evaluated HALE in the total life expectancy was small , and males had a greater proportion than female, and adults in rural areas had a greater proportion than that in urban areas. We should consider NCDS management for the elderly residents and to improve the life quality among the elderly residents.
ABSTRACT
Objective To evaluate risk and the direct economic burden of malignant tumor due to type 2 diabetes mellitus. Methods Combing the data of chronic disease surveillance, follow-up and the fifth health service investigation, we calculated the population attributable risk and the direct economic burden for malignant tumor due to type 2 diabetes mellitus in order to estimate the direct economic burden for tumor caused by type 2 diabetes mellitus. Results The relative risk was 1.68 (95%CI: 1.68-1.70) for people with type 2 diabetes mellitus to develop the malignant tumor than the people without type 2 diabetes mellitus. The proportions of attributable risk (AR%) and population attributable risk (PAR%) were 40.57% and 2.05%, respectively. Moreover, the annual average hospitalization costs for malignant tumor reached 11 billion CNY, which took part 6.48% of total health service costs. And the direct economic burden for malignant tumor due to type 2 diabetes mellitus was 0.228 billion CNY. In addition, the top two highest population attributable risks were colorectal cancer and liver cancer, while the top three greatest direct economic burdens for malignant tumor or malignant tumor due to type 2 diabetes mellitus were lung cancer, colorectal cancer and stomach cancer. Conclusion From this study, we found that type 2 diabetes mellitus increased the risks of tumor and therefore lead to sharply increasing in medical costs of malignant tumor. In order to decrease the risk of malignant tumor and medical costs, we should pay more attention to the prevention of type 2 diabetes mellitus and the screening of malignant tumor due to type 2 diabetes mellitus.
ABSTRACT
The microRNA-21 (miR-21) is known to play a major role in cancer progression; however, its function in the cardiovascular system appears to be even more complex and conflicting. To characterize miR-21 expression in the plasma of individuals with or without metabolic syndrome (MetS), 58 MetS cases and 96 non-MetS controls were investigated. Expression levels of miR-21 were significantly decreased in the circulation of MetS subjects (OR=0.52, 95% CI: 0.29-0.92) compared with that of non-MetS subjects. Body mass index (BMI) and the number of MetS components had a negative correlation with the level of miR-21, whereas age was inversely related to the level of miR-21. No significant difference was detected in miR-21 levels between the sexes (P=0.056). MiR-21 might be a negative regulating factor in MetS.

Objective To investigate the associations of lipoprotein lipase (LPL)gene Hind Ⅲ polymorphisms with hypertension combined with obesity and their lipids metabolism.Methods 326 subjects of hypertension combined with obesity and 326 healthy subjects were arranged to take questionnaires survey,physical examinations and blood biochemical tests.The LPL gene Hind Ⅲ polymorphisms were detected by PCR -RFLP.Regression analysis was used in this study. Results H +was the dominant allele in both groups.There was no significant difference among H +H +,H +H -, H -H -genotypes of LPL gene between the two groups (P >0.05).In the hypertension combined with obesity group, H +H +genotype had significantly higher triglyceride (TG),total cholesterol (TC)levels than H +H -/H -H -genotypes (P <0.05 )while no significantly different density lipoprotein cholesterol (HDLC)level (P >0.05 ).The results of conditional logistic regression analysis showed that high fasting blood glucose (FBG,adjusted OR =21.56, 95%CI:7.49 ~62.1 1 ),highTG(adjusted OR =7.5 1 ,95 % CI:4.20 ~1 3.43 ),lowHDLC(adjusted OR =2.67 ,95% CI:1.53 ~4.66),high uric acid (UA,adjusted OR =3.36 ,95% CI:1.55 ~7.29)and hypertension family history (adjusted OR =2.07,95% CI:1.21 ~3.55)were the main influencing factors of the hypertension combined with obesity (all P <0.05).Conclusion LPL Hind Ⅲ polymorphism is significantly associated with the lipids metabolism of the hypertension combined with obesity,but it is not an assured independent risk factor for hypertension combined with obesity.
ABSTRACT
Objective To explore the risk factors of lung cancer among non -smoking women.Methods A total of 229 new cases of lung cancer among non -smoking women from 2005 to 2008 were collected.The design method of 1 to 2 matching case -control study was used controlling age,sex and smoking conditions.The data was analyzed by univariate and multivariate conditional logistic regression analysis.Results Single factor analysis identified 13 risk factors (all P <0.05).The multivariate conditional logistic regression and factor analysis showed that respiratory disease history,family history of cancer,poor interpersonal relationship,psychological problems,feeling heavy smoke when cooking,consumption of salty and dry food,later menarche and passive smoking were risk factors (OR =24.427,5.539,3.041,2.622,1.856, 1.724,1.565 and 1.598 respectively),high income level and high consumption of vegetables were protective factors (OR =0.650 and 0.683 ).Conclusion respiratory disease history, family history of cancer, poor interpersonal relationship and psychological problems are main risk factors of lung cancer among non -smoking women.
ABSTRACT
Objective To analyze the characteristics and trend of incidence and mortality of thyroid cancer in Zhejiang Province from 2007 to 2011.Methods Data from cancer registry and death registry in Zhejiang province were used to calculate the crude incidence and mortality,age -specific incidence and mortality,China - and World -standardized incidence and mortality of thyroid cancer.Trend Chi -square test was used to analyze the trend of incidence and mortality. Results From 2007 to 2011,the reported incidence rate of thyroid cancer in Zhejiang Province was 8.37 /100,000 (China -and World -standardized incidence were 5.28 /100,000 and 6.14 /100,000 respectively).The mortality rate was 0.34 /100,000 (China -and World -standardized mortality were 0.17 /100,000 and 0.24 /100,000 respectively). The incidence and mortality were both significantly higher in females and urban residents than in males and rural residents (both P <0.01).With age increased,the mortality increased.However,the incidence increased at the beginning and then declined with a peak age of 30 -59.From 2007 to 2011,the incidence of thyroid cancer increased rapidly with a speed of 29.95% per year while the mortality did not show the similar trend.Conclusion The incidence of thyroid cancer in Zhejiang Province is growing rapidly and the relative risk factors should be taken into consideration in future researches.
ABSTRACT
Objective To analyze the survival rate of colorectal cancer,using data from the population-based cancer registry during 2005-2010 in Zhejiang.Methods The last follow-up activites on 17 235 cases regarding the survival status was December 31,2012.Both cumulative observed survival rate (OS) and relative survival rate (RS) were calculated with SURV 3.01 software drawn up by Hakulinen.Results The OS on 1,3 and 5 year were 76.71％,58.14％,50.58％ and the RS on 1,3 and 5 year were 78.93％,63.48％,58.73％,respectively.The 1,3 and 5 year relative survival rates on males vs.females were 79.36％ vs.78.35％,63.63％ vs.63.29％,and 58.85％ vs.58.57％,respectively and the difference between them was not statistically significant (x2=1.08,P=0.298).The 5 year OS and RS of the urban population were 55.06％ and 64.09％ and the 5 year OS and RS of the rural population were 47.59％ and 55.16％,with statistically significant differences (x2 =85.84,P＜0.001).The 55-64 age group appeared higher relative survival rate.There were significant differences in the survival rates among different age groups (x2=333.42,P＜0.001).The 5 year RS of colon vs.rectum were 61.47％ vs.56.45％.Colon patients showed better relative survival rate (x2=7.26,P＜0.05).Conclusion The wide variations in colorectal cancer survival rates were seen between the urban and rural populations.Public health resources should be focused on rural areas.Patients younger than 55 years should be under specific attention to further understand the related factors which influencing the prognosis of the diseases.

<p><b>OBJECTIVE</b>To explore the association between dyslipidemia and different subtypes of hypertension among Zhejiang population.</p><p><b>METHODS</b>From June to October in 2010, 19 113 local residents aged ≥ 18 years old were selected among 7571 families from fifteen counties in Zhejiang by four stage stratified-random sampling method. A self-designed questionnaire was adopted to collect information on demographic characteristics, physical activity and life style. At the same time, physical examinations including height, weight, blood pressure and blood lipids were carried out.</p><p><b>RESULTS</b>A total of 19 113 participants completed the interviews, physical examinations and collected the blood samples.Excluding those who did not meet the criteria, 14 731 were finally enrolled in the study. The prevalence rates of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), systolic and diastolic hypertension (SDH) were 7.16% (1055/14 731, standardized rate:5.46%), 4.60% (677/14 731, standardized rate:4.41%), 7.09% (1045/14 731, standardized rate:5.75%), respectively. Among normal blood pressure group, subjects with normal TC, high TC and abnormal TC were separately 10 571 (88.43%), 1173 (9.81%) and 210 (1.76%); subjects with normal HDL-C and low HDL-C were separately 6885 (57.60%) and 5069 (42.40%); subjects with normal TG, high TG, abnormal TG were separately 9952 (79.91%), 1213 (10.15%) and 1189(9.95%).In ISH group, subjects with normal TC, high TC and abnormal TC were separately 826 (78.29%), 188 (17.82%) and 41 (3.89%); subjects with normal HDL-C and low HDL-C were separately 666(63.13%) and 389 (36.87%); subjects with normal TG, high TG and abnormal TG were separately 737 (69.86%), 150 (14.22%) and 168 (15.92%). Multi factor analysis showed that high TG and abnormal TG were associated with ISH (OR (95%CI):1.43 (1.16-1.76), 1.65 (1.34-2.03) respectively). Among IDH group, subjects with normal TC, high TC, abnormal TC were separately 556(82.13%), 99(14.62%) and 22 (3.25%); subjects with normal HDL-C, low HDL-C were separately 335 (49.48%) and 342 (50.52%); subjects with normal TG, high TG, and abnormal TG separately were 402 (59.38%), 107 (15.81%) and 168 (24.82%). The multi factor analysis showed that high TG and abnormal TG could increase the risk of IDH (OR(95%CI):1.57 (1.24-1.98), 2.18 (1.76-2.70) respectively). Among SDH group, subjects with normal TC, high TC and abnormal TC were 817 (78.18%), 193 (18.47%) and 35 (3.35%); subjects with normal HDL-C and abnormal HDL-C were separately 599 (57.32%) and 446 (42.68%); subjects with normal TG, high TG, abnormal TG were separately 675 (64.59%), 164 (15.69%) and 206 (19.71%).
