[Impact of changes in malignant tumor death spectrum on life expectancy in Tianjin residents from 1999-2019].

Objective: To analyze the effects of changes in the spectrum of deaths from malignant tumors on the life expectancies of residents of different ages, sexes, and regions (urban or rural) in Tianjin from 1999 to 2019. Methods: The Abridged Life Table method and the Arriaga's decomposition method were used to calculate the effects of changes in spectrum of deaths from malignant tumors on the life expectancies of Tianjin residents of different ages, sexes, and regions. Results: During 1999-2019, the life expectancies increased by 4.96 years and 5.69 years for males and females, respectively, in Tianjin. The decreases in the mortalities from malignant neoplasms contributed 0.12 year (3.30%) and 0.03 year (0.77%) for males and females, respectively, to the increase during 1999-2007, and 0.05 year (3.13%) and 0.12 year (6.08%) for males and females, respectively, during 2007-2019. The decreases in the mortality rates of malignant tumors contributed the most to the increase among residents in the 60-69 years group, and the decreases in mortality rates of lung, gastric, esophageal, and liver cancers had relatively larger contribution. Lung cancer had a negative effect on the life expectancies of men and rural residents, but a positive effect on those of women and urban residents. The significant increases in the mortality rates of lung, colorectal, and pancreatic cancers in the ≥85 years group had a large negative effect on the overall life expectancy. Breast and ovarian cancers contributed negatively to the life expectancy of female residents. Conclusion: The overall increase in the life expectancy in Tianjin from 1999 to 2019 was mainly attributed to the elderly and the decreases in the mortality rates of gastric, esophageal, and liver cancers, among other malignancies, while the increases in the mortality rates of lung, colorectal, gallbladder, pancreatic, and breast cancers were the most significant factors hindering the increase of the life expectancy in Tianjin.

[Cancer survival analysis in Tianjin, 2010 to 2016].

Objective: Survival analysis of cancers' incidence data in Tianjin from 2010 to 2016 was conducted to provide the basis for formulating and evaluating regional health policies on cancer prevention and treatment. Methods: Registration data in Tianjin were used between January 1, 2010 to December 31, 2016 and patients were followed-up till 31 December, 2021. Life-table method was used to calculate the observed survival rate and Edered Ⅱ was used to calculate the relative survival rate. The data were stratified by year, gender, age group and cancer sites. Difference in survival curves between group was analyzed by Kaplan-Meier method and Log rank test. Joinpoint regression model was used to analyze the trend change. Results: The 5-year relative survival rates of cancer were 41.92% to 53.65% from 2010 to 2016 for residents in Tianjin, with an increasing trend (t=4.81, P=0.005), and the average was 48.56%. The survival rate of females was higher than that of males (57.71%vs. 39.20%), and the survival rate of urban residents was higher than that of rural residents (49.38% vs. 47.24%). The 5-year relative survival rates were 63.14%, 78.39%, 58.25% and 32.67% in 0-14, 15-44, 45-64 and 65 and above age groups, respectively. The median relative survival times of all cancer were 2.34 to 6.00 years from 2010 to 2016 in Tianjin, with an increasing trend (t=3.86, P=0.012). The average of median relative survival times was 4.11 years. The median survival time of females was longer than that of males (11.99 years vs. 2.03 years), and the time of urban residents were longer than that of rural residents (4.60 years vs. 3.43 years). The median relative survival time were 12.07, 11.92 and 1.34 years in 15-44, 45-64 and 65 and above age groups, respectively. Conclusions: The cumulative survival rate of cancer increased significantly from 2010 to 2016 in Tianjin, indicating that the prevention and treatment effect of cancer is obvious. The focus should be on male, rural areas, higher age group, and targeted prevention and treatment measures should be taken to lung, esophagus, liver, gallbladder and pancreatic cancer.

[Study on increase of average life expectancy of residents in Tianjin from 1999 to 2018].

Objective: To assess the trend and the factors responsible for the increase of life expectancy of residents in Tianjin over the past two decades. Methods: Abridged Life Table and Arriaga's decomposition method was applied to quantify the influence of the age structure and the leading causes of death on the increase of life expectancy of residents in Tianjin from 1999 to 2018. Results: In the past 20 years, the life expectancy of residents in Tianjin increased by 4.97 years, the life expectancy of men and women increased by 4.11 years and 5.86 years, respectively. The decrease of mortality rate in 0-year-old group contributed 19.17% to the increase of the life expectancy, while the decrease of mortality rate in residents aged ≥55 years contributed more to the increase of life expectancy, with the cumulative contribution rate of 67.38%. The major contribution to the increase of life expectancy was the mortality reduction of cerebrovascular disease, respiratory disease, cardiovascular disease, perinatal diseases, congenital malformations and injury, with the contribution percentage of 27.27%, 21.37%, 15.76%, 12.22%, 6.44% and 4.86%, respectively. The increase of mortality of malignant tumor, injury and poisoning, diabetes and nervous system diseases and others had a negative effect on the increase of life expectancy of people aged ≥75 years. From 1999 to 2018, the life expectancy increased from 76.72 years to 81.46 years (t=9.11, P<0.001), the annual percent change (APC) was 0.58%. From 2011 to 2018, it was stable, ranging from 81.46 years to 81.69 years (t=0.89, P=0.387, APC=0.13%). Conclusion: From 1999 to 2018, the increase of life expectancy was attributed to the decrease of mortalities in infants and the elderly and the decrease of mortalities of cerebro-cardiovascular disease, respiratory disease, perinatal disease, congenital malformations and injury. However, these positive contributions were partly offset by the negative contribution of malignant tumor, injury, diabetes and nervous system disease in those aged ≥75 years. Comprehensive prevention and control of key diseases should be strengthened in key population in order to further improve the life expectancy of the population.

[Study on the diet balance index and its relationship with blood uric acid of smoking adults in Tianjin].

Objective: Diet balance index (DBI_16) was used to evaluate the dietary status of smoking adults in Tianjin, and the relationship between DBI_16 and serum uric acid was analyzed. Methods: A total of 1 478 inhabitants aged 18 and above were enrolled. The dietary status was obtained with a 3-day dietary recall and condiment weighing method. And their fasting venous blood was collected to detect uric acid. Food intake and DBI_16 scores of smokers and non-smokers were described, and the relationship among smoking, diet quality distance (DQD-DBI), and serum uric acid was analyzed. Results: The intake of vegetables, fruits, and milk of smokers in Tianjin was lower than while the salt, oil, cereals, and aquatic products were higher than that of non-smokers. The DBI_16 scores of vegetables and fruits, food types, milk, and beans of smokers were lower than those of non-smokers in Tianjin, and the scores of pure energy foods and condiments were higher than those of the non-smokers. The DQD-DBI, high bound score and low bound score of smokers in Tianjin were 42.0, 14.0, and 29.0 respectively, which were all higher than those of non-smokers. The main problems appeared as moderately inadequate intake (accounting for 67.0%), low, excessive intake (accounting for 70.9%), and moderate imbalance of intake (accounting for 67.2%). The serum uric acid of smokers was higher than in the non-smokers, and there the same result appeared under the conditions of "not suitable" in DQD-DBI. Conclusions: In Tianjin, the dietary imbalance was more evident in smokers than the non-smokers, and the serum uric acid was significantly higher than the non-smokers. Strategies as strengthening the nutrition education and intervention targeted for smokers were in urgent need.

[Study of influence of birth weight on risk of chronic diseases and blood uric acid in adulthood].

Objective: To understand the influence of birth weight on the risk of chronic diseases, such as hypertension and diabetes, and the relationship between birth weight and serum uric acid in adulthood. Methods: According to the Chinese Adult Chronic Disease and Nutrition Surveillance Program, a total of 1 131 residents aged 18 years and above were enrolled from Hexi, Nankai, Hongqiao, Wuqing, Jinnan, Baodi and Jizhou districts of Tianjin. The data of birth weight and blood pressure of the residents were collected, and fasting venous blood samples were collected from them to detect uric acid, blood glucose and blood lipids levels. The distribution of birth weight of the surveyed population was described, and the relationship between birth weight and chronic diseases, such as hypertension and diabetes, and the blood uric acid level in adulthood were analyzed. Results: The average birth weight of the surveyed population in Tianjin was 3.37 kg, which was higher in males than in females. No matter overweight/obesity, hypertension or diabetes, the prevalence rate of normal birth weight was the lowest in adulthood. After univariate logistic regression analysis and adjusting for age, sex, smoking and drinking status, it was found that compared with normal birth weight, low birth weight had a stronger correlation with diabetes (OR=2.91,95%CI:1.46-5.76) and dyslipidemia (OR=1.79,95%CI:1.01-3.19) in adulthood. Macrosomia was strongly associated with overweight/obesity in adulthood (OR=1.47, 95%CI:1.08-2.01). There was no significant difference in serum uric acid level among the residents with different birth weights. Conclusions: The low birth weight of the surveyed population in Tianjin was closely related to the risk of diabetes and dyslipidemia in adulthood, and the macrosomia was closely related to the risk of overweight/obesity in adulthood.

[Analysis on long-term trend of mortality and years of life lost of breast cancer in women in Tianjin, 1999-2017].

Objective: To analyze the trends of mortality and years of life lost (YLL) of breast cancer in women in Tianjin and provide references for the development of intervention strategies. Methods: The crude mortality rate, standard mortality rate, cumulative rate (0-74 years old) and truncated rate (35-64 years old) of breast cancer in women in Tianjin from 1999 to 2017 were calculated. The annual percentage change of the mortality rate and YLL rate were analyzed by Joinpoint regression. Results: From 1999 to 2017, a total of 8 356 deaths of breast cancer were reported in Tianjin, resulting in a YLL of 262 835.53 person-years. The average crude mortality rate was 9.15/100 000. The average age standardized rate(ASR) (World) was 6.14/100 000. The ratio of ASR (World) between urban and rural areas was 1.73∶1. The peak mortality ratio of age groups between urban area and rural area was 3.13∶1. From 1999 to 2017, both the crude mortality rate and ASR of breast cancer in Tianjin had rising trends. In 2017, the crude mortality rate and the ASR of breast cancer increased by 113.7% and 44.4% respectively compared with 1999. The increase of urban mortality mainly came from elderly group aged ≥75 years, and the mortality of young age groups in rural area showed an fast increases, which was most obvious in age group 45-59 years (average annual percentage change=3.6%, P<0.01). Conclusions: The mortality rate of breast cancer and disease burden in women in Tianjin are still in rapid increase. We should continue to implement the prevention and control strategies such as lifestyle intervention and screening of key groups. More attention need to be paid to the increase of breast cancer incidence in rural area.

Reduced long non-coding RNA PTENP1 contributed to proliferation and invasion via miR-19b/MTUS1 axis in patients with cervical cancer.

OBJECTIVE: Many studies showed that long non-coding RNAs (lncRNAs) may serve as prospective markers for patients with malignant cancers, including cervical cancer (CC). In this study, we mainly investigate the functions of lncRNA PTENP1 in the progression of human CC. MATERIALS AND METHODS: Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to detect expression levels of PTENP1, miR-19b and MTUS1 in CC tissues, the adjacent tissues and CC cell lines. The correlations between PTENP1 with miR-19b, miR-19b with MTUS1 and PTENP1 with MTUS1 were analyzed. Overall survival (OS) of patients was analyzed using Kaplan-Meier method. Proliferation capacity was measured by CCK-8 assay and the invasion ability in CC cell line was detected by transwell assay. Western blot (WB) assay was performed to measure protein levels of tissues and CC cell lines. Finally, Dual-Luciferase reporter assay was performed to prove the potential binding sites between PTENP1 and miR-19b, miR-19b and MTUS1. RESULTS: We found that PTENP1 was reduced in CC tissues and CC cell lines, which predicted the poor diagnosis of CC patients. MiR-19b was increased in CC tissues, which was negatively correlated with PTENP1 in CC tissues. MTUS1 was reduced in CC tissues, which was negatively correlated with miR-19b and positively correlated within PTENP1 CC tissues. Furthermore, PTENP1 overexpression inhibited cell proliferation ability and invasion capacity in HeLa cells, as well as repressed expressions of Cyclin D1, N-cadherin, and Vimentin. Moreover, Luciferase gene reporter assays verified that miR-19b was a direct target miRNA of PTENP1, and MTUS1 was identified as a direct target of miR-19b. In addition, the inhibited cell proliferation and invasion abilities in HeLa cells with p-PTENP1 were eliminated following with miR-19b mimic transfection. CONCLUSIONS: According to the results, this study showed that PTENP1 was reduced in CC patients and it was a prognostic factor for CC patients. Furthermore, we firstly uncovered that PTENP1 could inhibit cell proliferation and invasion via miR-19b/MTUS1 in CC patients, which uncovered the tumor-suppressive role of PTENP1 in CC and suggested that it might be a potential target for treating human CC.

[The role of SMARCE1 in the diagnosis of clear cell meningioma].

Objective: To analyze the expression of SMARCE1 in clear cell meningioma (CCM), and evaluate the role of SMARCE1 in the differential diagnosis in morphologically similar diseases. Methods: Thirteen samples/11 cases of CCMs were collected from the First Affiliated Hospital of Fujian Medical University, Shandong Provincial Hospital, Xuanwu Hospital of Capital Medical University and Thaihe Hospital of Hubei Province from January 2000 to December 2018, as well as 17 cases of meningiomas with clear-cell-like morphology, 782 cases of other types of meningiomas and other intracranial tumors with clear-like morphology. A tissue microarray was made using these cases, on which immunohistochemical/histochemical staining of SMARCE1, SSTR2, EMA, Ki-67, p53, PAS and D-PAS were performed. Result: The tumor cells of CCM had sheet-like architecture, without typical whorl formation.The CCM had round to polygonal cells, with clear, glycogen-rich cytoplasm and prominent blocky perivascular and interstitial collagen. The immunohistochemistry staining showed that none of the CCMs expressed SMARCE1(0/13).However, all of the other types of lesions, including meningioma(782/782), meningiomas with clear-like morphology(17/17), intracranial metastatic clear cell renal cell carcinoma(10/10), haemangioblastoma(10/10), central neurocytoma(10/10), oligodendroglioma(10/10), ependymoma(13/13), lioblastoma(42/42), and solitary fibrous tumor/hemangiopericytoma(35/35) showed positive nuclear staining of SMARCE1. Ki-67 index were 1%-5%, and p53 positive-rate were 0-40% in CCMs. PAS stain showed cytoplasmic granular positive and D-PAS were negative in all CCMs and meningiomas with clear-like morphology. Conclusion: SMARCE1 is a useful marker for the diagnosis of CCM and its mimickers.

[Analysis of the long-term trend of mortality and years of life lost of gastric cancer in Tianjin from 1999 to 2015].

Objective: To analyze the long-term trend of mortality and years of life lost (YLL) of gastric cancer in Tianjin from 1999 to 2015. Methods: From January 1, 1999 to December 31, 2015, the data of gastric cancer deaths was collected from the Tianjin death surveillance system. The inclusion criteria of death due to gastric cancer were coded by using 151 in the 9(th) edition of the international classification of diseases (ICD) (1999-2002) and C16 in the 10(th) edition of ICD (2003-2015). The crude and age-standardized mortality rate (ASR) of gastric cancer was calculated according to Segi's world standard population. YLL was calculated according to the standard method of the disease burden of WHO. The Joinpoint regression was used to calculate the average annual percentage change (AAPC) to indicate the trend of mortality and YLL of gastric cancer. Results: From 1999 to 2015, there were 20 000 deaths of gastric cancer in Tianjin. The proportion of gastric cancer death in the population aged 0-44 years old, 45-64 years old, and 65 years old and above was 4.9%, 30.4%, and 64.8%, respectively. The proportion of males and urban was 67.1% and 67.5%, respectively. From 1999 to 2015, the crude mortality rate was from 12.10/100 000 to 12.58/100 000. The ASR was from 11.04/100 000 to 7.24/100 000. The average annual YLL number was 29 625.83 person-years and the rate was 3.09 person-years per thousand people. From 1999 to 2015, the crude mortality rate and the PYLL of gastric cancer in Tianjin were stable (the AAPC was 0.34% and -0.24%, all P values >0.05). The ASR showed a downward trend (AAPC=-2.58%, P<0.001). Conclusion: From 1999 to 2015, the ASR of gastric cancer in Tianjin showed a downward trend, and the YLL of gastric cancer was stable.

[Status quo on smoking and related change pattern of smoking related behavior in past 20 years in urban residents in Tianjin].

Objective: To understand the status quo of smoking and change pattern of smoking related behaviors in the past 20 years in the urban adults in Tianjin. Methods: Data was from the study of Chinese Chronic Disease and Risk Factors (2015). Multi stage stratified random sampling method was used to conduct a questionnaire survey in 7 surveillance sites in Tianjin. Results: in the urban residents aged>20 years were compared with those in surveys in 1996 and 2010. Results In 2015, the smoking rate in men and women aged>20 years in Tianjin were 41.1% and 4.5% respectively. The average age of starting smoking was (19.2±4.7) years for men and (24.8±10.9) years for women, showing a younger age trend. Compared with the data from 1996 and 2010, the smoking rate in the urban residents was in decrease, but the rate of successful smoking cessation was in increase in 2015, the differences were significant. Conclusions: Since 1996, the rate of smoking in the urban residents of Tianjin has been in decline, however it is still at a high level, especially in women. The average age of starting smoking remains to be younger. It is necessary to strengthen the health education about harm of smoking in adolescents.

[Analysis on the alterative trend of colorectal cancer mortality from 1999 to 2015 in Tianjin of China].

Objective: To investigate the mortality of colorectal cancer and its trend from 1999 to 2015 in Tianjin, China, and to explore the mortality features in different populations in order to provide data for prevention and control strategies of colorectal cancer. Methods: Colorectal cancer mortality data between 1999 and 2015 were collected from Tianjin population - based mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Population data of permanent residents were collected from Tianjin Municipal Public Security Bureau. The number of new cases and deaths, incidence [including crude incidence, age-adjusted standardized incidence and 95% confidence interval (95% CI)], and mortality (including crude mortality, age-adjusted standardized mortality and 95% CI) of colorectal cancer were calculated. Standardized incidence and mortality of colorectal cancer were calculated using the Segi's world standard population, adjusted with age and gender. JoinPoint regression and Cochran-Armitage trend test were used to determine the statistical significance of differences in mortality trend. Results: A total of 31 376 new onset cases and 14 893 death cases of colorectal cancer were observed in Tianjin from 1999 to 2015. Colorectal cancer incidence increased from 1999 to 2015 with a standardized rate from 9.66/100 000 to 15.36/100 000 [annual percent change(APC)=3.48%, Z=23.21, P<0.001]. Colorectal cancer mortality increased from 1999 to 2015 with a standardized rate from 5.18/100 000 to 6.11/100 000 (APC=1.24%, Z=5.69, P<0.001). Both showed an increasing trend. The death proportion of colon cancer increased (39.67% in 1999 and 50.33% in 2015), while the death proportion of rectal caner decreased (60.33% in 1999 and 48.57% in 2015). The median age of colorectal cancer onset fluctuated steadily around 66 years old (APC=0.16, T=1.75, P=0.100); the median age of death increased from 69 to 73 years old (APC=0.43, T=8.81, P<0.001). From 1999 to 2015, the mortality of colorectal cancer showed a downward trend (all P<0.05) in the age groups of <35 and 35-44 years, while an upward trend (all P<0.05) in the age groups of 45-54 years, 55-64 years and ≥ 65 years. Colorectal cancer mortality in males increased with a standardized rate of 5.53/100 000 in 1999 to 7.33/100 000 in 2015(APC=2.29%, Z=7.86, P<0.001), while colorectal cancer mortality in females flatted with a standardized rate of 4.83/100 000 in 1999 to 4.89/100 000 in 2015 (APC=0.10%, Z=-0.30, P=0.752). Colorectal cancer mortality increased with a standardized rate of 6.75/100 000 in 1999 to 7.33/100 000 in 2015 (APC=0.54%, Z=1.98, P=0.048) in urban areas and of 3.18/100 000 in 1999 to 4.38/100 000 in 2015 (APC=2.47, Z=6.46, P<0.001) in rural areas, whose differences were significant. Standardized mortality rate in rural area was lower but the rising velocity was faster as compared to urban area. Conclusions: Crude mortality and standardized mortality of colorectal cancer increase from 1999 to 2015 in Tianjin population. The people of elder, male and urban area have higher mortality. The mortality in people of male and rural area presents a faster rising state. Further efforts to reduce colorectal cancer mortality in Tianjin are needed to prevention and control of colorectal cancer.
