Objective:To investigate the lung cancer incidence and mortality in 2016 and their trends from 2002 to 2016 in shanghai. Methods:The data of incidence and death on lung cancer in shanghai from 2002 to 2016 were obtained from the Shanghai Municipal Center for Disease Control and Prevention population-based cancer registry and Vital Statistics System.Lung Cancer incidence and mortality stratified by age of diagnosis or death,gender and age-group were analyzed.The number of cases and deaths,proportion,crude rates,age-specific rates,age-standardized rates,corresponding truncated age-standardized rates(35-64 years)and cumulative rates were calculated.Segi's 1960 world standard population was used for calculating age-standardized rates of incidence and mortality as well as truncated age-standardized rates.Trends in age-standardized rates of incidence and death for lung cancer in Shanghai from 2002-2016 were estimated by Joinpoint analysis and characterized by the annual percent change(APC). Results:The new lung cancer cases and deaths were 14 395 and 9 170 in Shanghai in 2016.The crude rate of incidence was 99.41/105,and the age-standardized rate of incidence was 39.76/105.New cases of lung cancer accounted for 19.34％of all malignant tumors in shanghai,ranking the first in the incidence spectrum of malignant tumors.The crude rate of mortality was 63.33/105,and the age-standardized rate was 21.57/105.Deaths of lung cancer accounted for 24.78％of all malignant tumor deaths in shanghai,ranking the first in the mortality spectrum of malignant tumors.The age-standardized rates of incidence and mortality for males were higher than those for females.The age-specific numbers and rates of incidence and mortality increased with age.The age-specific number and rate of incidence reached the peak at the age group of 60-64 years and 80-84 years respectively,and those of mortality peaked at the age group of 80-84 years and older than 85 years respectively.The incidence of lung cancer increased from 33.70/105 in 2002 to 39.76/1 05 in 2016 in Shanghai.Joinpoint analyses showed that the age-standardized rate of lung cancer incidence remained stable from 2002 to 2010(APC=-0.79,t=-1.46,P=0.175)but showed a significant upward trend with an average annual increase rate of 5.12％from 2010 to 2016(APC=5.12,t=6.97,P＜0.001).The standardized mortality showed a downward trend with an average annual decrease rate of 0.87％from 2002 to 2016(APC=-0.87,t=-2.87,P=0.013). Conclusion:The incidence of lung cancer in Shanghai during 2002-2016 presented an upward trend while the mortality of lung cancer showed a gradual downward trend.There are differences in the incidence and mortality of lung cancer among different gender and age groups.

Objective:To investigate the effects of miRNA-499a-5p targeting CD38 on cardiomyocyte injury induced by hydrogen peroxide (H 2O 2) and the possible mechanism. Methods:H9c2 cardiomyocytes were cultured in vitro and induced with H 2O 2 to establish the cardiomyocyte injury model. Four groups including control, H 2O 2, H 2O 2+ negative control (NC) and H 2O 2+ miRNA-499a-5p groups were set up. Real-time quantitative PCR (RT-qPCR) and Western blot were used to detect the expression of miRNA-499a-5p and CD38 in cardiomyocytes, respectively. MTT assay was used to measure the survival rates of cardiomyocytes. The levels of reactive oxygen species (ROS) and the activity of lactate dehydrogenase (LDH) were analyzed with test kits. Annexin V-FITC/PI double staining method was used to detect the apoptosis rates of cardiomyocytes. Western blot was used to detect the expression of B-cell lymphoma/leukemia-2 (Bcl-2), Bcl-2-related X protein (Bax), phosphoinositide 3-kinase (PI3K), phosphorylated PI3K (p-PI3K), protein kinase B (Akt) and phosphorylated Akt (p-Akt). Dual luciferase reporter assay was used to detect the targeting relationship between miRNA-499a-5p and CD38. Results:Compared with the control group, the expression of miRNA-499a-5p, Bcl-2, p-PI3K and p-Akt and the survival rate of cardiomyocytes were significantly reduced in the H 2O 2 group ( P<0.05), while the expression of CD38 and Bax, ROS level, LDH activity and the apoptosis rate were significantly increased ( P<0.05). Compared with the H 2O 2 group, the expression of miRNA-499a-5p, Bcl-2, p-PI3K and p-Akt and the survival rate of cardiomyocytes were significantly increased in the H 2O 2+ miRNA-499a-5p group ( P<0.05), while the expression of CD38 and Bax, ROS level, LDH activity and the apoptosis rate were significantly decreased ( P<0.05). Dual luciferase reporter assay confirmed that CD38 was a target gene of miRNA-499a-5p. Conclusions:miRNA-499a-5p could alleviate H 2O 2-induced cardiomyocyte injury by inhibiting the expression of CD38 and the PI3K/Akt signaling pathway might be involved.

Objective:To study the risk of malnutrition and related factors of cancer patients in community of Shanghai.Methods:From October 2018 to January 2019, four communities, Pengpu New Village Street, Pengpu Town, Jiangning Road Street, and Caojiadu Street, from 14 communities in Jing ′an District, Shanghai City, were selected by using a random cluster sampling method based on the Shanghai Cancer Registration and reporting system. All cases of malignant tumors and benign tumors of the central nervous system were included. A total of 4 396 questionnaires were distributed. After the exclusion of 9 invalid questionnaires, 3 310 valid questionnaires were included with a rate of 99.73%. A self-designed questionnaire was used to collect data including basic demographic characteristics, history of malignant, physical and psychological pain, nutritional demands and cognitive status. Malnutrition Universal Screening Tools (MUST) was used to analyze the nutritional risk of cancer patients in the community. Multivariate logistic regression model was applied to analyze potential factors.Results:Among the 3 310 cancer patients who completed the survey, the average age of study participants was (64.05±13.02), and 1 467 cases (44.32%) were males. The incidence rate of nutritional risk was 12.84% (425/3 310). The result of logistic regression analysis showed that compared with male, other cancer patients and no physical pain, the risk factors of the occurrence of nutritional included: female ( OR=1.53,95% CI:1.23-1.92), head and neck malignant tumors ( OR=1.42,95% CI:1.07-1.90), bronchus/lung malignant tumors ( OR=1.93,95% CI:1.43-2.61), liver, biliary/pancreatic malignant tumors ( OR=2.11,95% CI:1.21-3.65) and upper gastrointestinal malignant tumors ( OR=6.04,95% CI:4.31-8.46), patients with physical pain ( OR=1.39,95% CI:1.02-1.89). Conclusion:Nutritional risk of cancer patients is higher in community of Shanghai. Gender, location of tumors and physical pain are associated with the occurrence of nutritional risk.

Objective: To investigate the effects of miR-27b targeting ten-eleven translocation methylcytosine dioxygenase 2 (TET2) on oxidized low-density lipoprotein (ox-LDL) induced inflammatory responses and apoptosis in endothelial cells. Methods: Double luciferase reporter gene analysis verified the targeting effect of miR-27b on TET2. Human umbilical vein endothelial cells (HUVECs) were induced by ox-LDL in vitro. Eight groups were set up including control group, ox-LDL group, ox-LDL+ anti-miR-con group, ox-LDL+ anti-miR-27b group, ox-LDL+ pcDNA group, ox-LDL+ pcDNA-TET2 group, anti-miR-27b+ si-con group and anti-miR-27b+ si-TET2 group. qRT-PCR was used to detect the expression of miR-27b and TET2 at mRNA level. Cell viability was detected by MTT assay. Cell apoptosis rate was detected by flow cytometry. Western blot was used to detect the expression of TET2, Cyclin D1 and caspase-3 at protein level. Results: TET2 was the target gene of miR-27b. TET2 expression could be negatively regulated by miR-27b. ox-LDL increased the expression of miR-27b and reduced the expression of TET2 in HUVECs. The secretion of inflammatory factors and apoptosis rates of HUVECs in the control, ox-LDL+ anti-miR-27b, ox-LDL+ pcDNA-TET2 and anti-miR-27b+ si-con groups were significantly lower than those in the ox-LDL, ox-LDL+ anti-miR-con, ox-LDL+ pcDNA and anti-miR-27b+ si-TET2 groups, respectively (P<0.05). Conclusions miR-27b promoted ox-LDL-induced inflammatory responses and apoptosis in endothelial cells through down-regulating the expression of TET2.

Objective: The registration data of local cancer registries from 2008 to 2012 were collected by National Central Cancer Registry to estimate the incidence and mortality of female breast cancer in China. Methods: Data from 135 registries were qualified and selected in the final analysis, and each registry at least has submitted data from 2010 to 2012. Cancer incidence and mortality analyses were stratified by area (urban/rural, eastern/middle/western areas) and age group. The age composition of standard population of Chinese census in 2000 and Segi′s population were used for age-standardized incidence and mortality in China and worldwide, respectively. Results: A total of 135 registries were recruited in the analysis, covering 629 333 910 person-years (382 669 450 in urban and 246 664 460 in rural). About 13, 258 cases of female breast cancer were diagnosed and 32 205 cases were dead between 2008 and 2012. Female breast cancer incidence was 42.67/100, 000 and age-standardized rate calculated by worldwide standard population was 28.87/100, 000. The crude incidence of urban area was 51.85/100, 000, higher than 28.29/100, 000 of rural area, and the crude incidence of eastern area was 46.35/100, 000, higher than 36.38/100, 000 of middle area and 27.60/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age 55-59 (96.36/100, 000), and declined at age 60. The age-standardized incidence rate by Chinese standard population increased 30.56% from 2003 to 2012. The increase rate of rural area was 72.32%, faster than 23.48% of urban area. Female breast cancer mortality was 10.36/100, 000 and the age-standardized rate calculated by worldwide standard population was 6.61/100, 000. The crude mortality of urban area was 11.64/100, 000, higher than 8.36/100, 000 of rural area, and the crude mortality of eastern area was 10.81/100, 000, higher than 7.38/100, 000 of middle area and 9.90/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age above 85 (61.25/100, 000). Age-standardized incidence rate by Chinese standard population remained stable during the period of 2003-2012 (6.23%). The mortality rate mainly increased in rural area (54.94%), while decreased 2.32% in urban area over the 10 years. Conclusions Although the incidence and mortality of breast cancer in China are comparatively low worldwide, in China the incidence and mortality of female breast cancer have rose to the first and sixth place respectively among all the female cancers. The disease burden of breast cancer is very different between urban and rural area. Therefore, the targeted measure and strategy of control and prevention according to the area difference are needed.

Organized,population-based colorectal cancer (CRC) screening has been implemented in various cities of China in order to control its rising threat.General practitioners (GPs) play a crucial role as central coordinators among potential screening participants,service providers and program organizers.However,rates of participation and adherence to CRC screening program remain low,whilst its program performance indicators are increasingly receiving more attention.In this review,we summarize the latest literature focusing on strategies to optimize the role of GPs in different stages of organized CRC screening programs,which could substantially enhance screening efficiency and cost-effectiveness of population-based screening programs.

Background and purpose:Head and neck cancer is common worldwide. This article aimed to describe the patterns of incidence of head and neck cancer and their changes in Shanghai from 2003 to 2012, in order to provide reference for prevention programs, research and control strategies on cancer.Methods:The data of lip, oral cavity and pharynx cancer cases were collected by the Shanghai Cancer Registry. The distributions of Shanghai lip, oral cavity and pharynx cancer incidences from 2003 to 2012 were described. The patterns were described according to gender, age, basis of diagnosis, histological type, diagnostic stage in detail. We compared incidences of recent 5 years (from 2008 to 2012) with those of previous 5 years (from 2003 to 2007).Results:On average from 2003 to 2012, 1105 new cases of head and neck cancer were diagnosed in Shanghai each year, with 2.08% among the total cancer cases. The crude rate was 8.01 per 100000 and the age-standardized rate was 4.45 per 100000. Nasopharyngeal cancer was the major subtype of the head and neck cancer, with 50.81% among the total head and neck cases. The crude and age-standardized rates among males were higher than those among females. The histologically verified percentage was 85.77%. The squamous carcinoma was the major histological type, with 57.58% among the total cases. The age-stan-dardized rate of nasopharyngeal cancer was in decline.Conclusion:The incidence of head and neck cancer was low in Shanghai during the past 10 years. Male cases were more than female cases. The major histological type was squamous carcinoma. Half of new cases were nasopharyngeal cancer which appeared to affect patients at a relatively young age. Patients with nasopharyngeal cancer were diagnosed at relatively advanced stages.
