Cause Of Death In China Research Articles

Geographical Variation of COPD Mortality and Related Risk Factors in Jiading District, Shanghai.

Background: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in China. Although numerous studies have been conducted to determine the risk factors for COPD mortality such as ambient air pollution, the results are not fully consistent.Methods: This study included mortality analysis and a case-control design by using the data extracted from the Mortality Registration System in Jiading District, Shanghai. Traditional logistic regression, geographically weighted logistic regression (GWLR), and spatial scan statistical analysis were performed to explore the geographic variation of COPD mortality and the possible influencing factors.Results: Traditional logistic regression showed that extreme lower temperature in the month prior to death, shorter distance to highway, lower GDP level were associated with increased COPD mortality. GWRL model further demonstrated obvious geographical discrepancies for the above associations. We additionally identified a significant cluster of low COPD mortality (OR = 0.36, P = 0.002) in the southwest region of Jiading District with a radius of 3.55 km by using the Bernoulli model. The geographical variation in age-standardized mortality rate for COPD in Jiading District was explained to a certain degree by these factors.Conclusion: The risk of COPD mortality in Jiading District showed obvious geographical variation, which were partially explained by the geographical variations in effects of the extreme low temperature in the month prior to death, residential proximity to highway, and GDP level.

Trend of the mortality of major liver diseases and its impact on life expectancy in China from 2006 to 2017

Liver diseases are the serious cause of death in China. We aim to describe the trends and disparities of major liver disease mortality rates and the loss of life expectancy (LLE) in China. Annual percentage change (APC) and average APC (AAPC) were calculated using the Joinpoint regression model. LLE was calculated using cause eliminated life table. From 2006 to 2017, the overall age-standardized mortality rate (ASMR) of liver cirrhosis lightly declined (AAPC: -2.97%), whereas the ASMR of viral hepatitis and liver cancer remained stable. Viral hepatitis (AAPC: -4.36%) and liver cirrhosis (AAPC: -4.35%) ASMRs both declined for females. The highest ASMRs of viral hepatitis and liver cirrhosis were in the west region, while that of liver cancer was in the middle region. The ASMRs of liver cirrhosis in the middle region and liver cancer in the east region significantly decreased. The means of LLE on viral hepatitis, liver cirrhosis and liver cancer were 0.05, 0.1 and 0.46years, respectively. The burden of liver diseases is still severe and there are disparities between genders and different regions in China. Accurate early diagnostic approaches for high-risk populations should be established to eliminate the burden of liver diseases.

Long non-coding RNA LOC366613 alleviates the cerebral ischemic injury via regulating the miR-532-5p/phosphatase and tensin homolog axis

ABSTRACT Cerebral infarction (CI) has become a leading cause of death in China. Long non-coding RNAs (lncRNAs) are intensively involved in the progression of CI. Here, we aimed to investigate the effects of lncRNA LOC366613 (LOC366613) on cerebral I/R injury, as well as its possible mechanism. Transient middle cerebral artery occlusion (MCAO) was used to establish a mouse model of cerebral I/R, and the PC12 cell line was used to establish an in vitro oxygen-glucose deprivation (OGD) injury model. The MTT assay was used to determine cell viability, and qRT-PCR was used to determine RNA levels. Western blotting was conducted to detect protein expression levels. The TUNEL assay and flow cytometry were used to measure cell apoptosis, and 2,3,5-triphenyltetrazolium chloride (TTC) was used to determine cerebral infarct volume. Finally, RNA pull-down and luciferase activity assays were used to examine interactions between miR-532-5p and LOC366613, as well as between miR-532-5p and phosphatase and tensin homolog (PTEN). LOC366613 was overexpressed in patients with cerebral I/R injury. In PC12 cells, knockdown of LOC366613 reduced the apoptosis rate and lactic acid dehydrogenase (LDH) expression, while increasing cell viability. Moreover, miR-532-5p was shown to be a target of LOC366613, as predicted. Downregulation of miR-532-5p reversed the effects of LOC366613 knockdown on PC12 cell apoptosis, LDH release, and cell viability. Finally, PTEN was verified as a target of miR-532-5p. LOC366613 participates in cerebral I/R injury by regulating the miR-532-5p/PTEN axis, potentially providing a new CI treatment target.

Role of Polyphenols as Antioxidant Supplementation in Ischemic Stroke.

Stroke is the second most common cause of death globally and the leading cause of death in China. The pathogenesis of cerebral ischemia injury is complex, and oxidative stress plays an important role in the fundamental pathologic progression of cerebral damage in ischemic stroke. Previous studies have preliminarily confirmed that oxidative stress should be a potential therapeutic target and antioxidant as a treatment strategy for ischemic stroke. Emerging experimental studies have demonstrated that polyphenols exert the antioxidant potential to play the neuroprotection role after ischemic stroke. This comprehensive review summarizes antioxidant effects of some polyphenols, which have the most inhibition effects on reactive oxygen species generation and oxidative stress after ischemic stroke.

Burden of cardiovascular disease from 1990 to 2017 in Henan Province, China

ABSTRACT Background Cardiovascular diseases (CVDs) are the leading causes of death in China. Little is known about the CVD burden and risk factors in Henan Province, China. Objective To analyze the CVD burden and main risk factors between 1990 and 2017 in the Henan Province in China. Methods The methodological framework and analytical strategies adopted in the Global Burden of Disease Study 2017 were used. Results (1) Age-standardized mortality rate attributed to CVDs increased from 355.0 per 100,000 persons in 1990 to 364.1 per 100,000 persons in 2017 in Henan. (2) Age-standardized disability adjusted life years (DALYs) rate fell by 3.9% from 1990 to 2017. However, the number of DALYs attributed to CVDs increased by 75.9% from 4.2 million person-years in 1990 to 7.3 million person-years in 2017. (3) The age-standardized years lived with disability (YLDs) rate increased by 27.5% from 1990 to 2017. However, years of life lost (YLLs) rate decreased by 6.7% from 1990 to 2017. The contribution of YLLs to the DALYs decreased from 91.4% in 1990 to 89.2% in 2017. (4) Stroke (52.3%) and ischemic heart diseases (38.8%) accounted for 91.1% of total CVDs DALYs among adults in 2017. (5) Dietary factors such as high intake of sodium, alcohol use and low intake of fruits, high systolic blood pressure, and tobacco use were the top risk factors for CVDs, and the estimated population attributable fraction in 2017 was 69.4%, 56.7% and 25.2%, respectively. Conclusions The absolute burden of CVDs in Henan is still high, although age-standardized DALYs declined between 1990 and 2017. The prevention and control of stroke and ischemic heart diseases should focus on a few modifiable risk factors which mainly contributed to the burden of CVDs, such as dietary factors, high systolic blood pressure, and tobacco use.

Stroke Mortality Attributable to Low Fruit Intake in China: A Joinpoint and Age-Period-Cohort Analysis.

Stroke is the first leading cause of death in China, and low fruit intake is suggested to be one of the most important risk factors for stroke mortality. However, the trends of stroke mortality attributable to low fruit intake remain unclear in China. Therefore, this study aimed to investigate the long-term trends of stroke mortality attributable to low fruit intake by sex in China during 1990–2017. Data were obtained from the Global Burden of Disease 2017 study; the annual percentage change (APC) and average annual percentage change (AAPC) were estimated by joinpoint regression analysis, and the net age, period, and cohort effects were estimated using the age–period–cohort model with an intrinsic estimator algorithm (APC-IE). The crude mortality rates (CMRs) increased for males and decreased for females from 1990 to 2017. The age-standardized mortality rates (ASMRs) for both males and females showed consecutive significant declines from 1990 to 2017. By APC analysis, substantially increasing age effects were presented from 25 to 79 years for both sexes. The independent period and cohort effects progressively decreased during the entire period for both sexes, with a faster decrease for females than for males. Males and elder groups were the high-risk population for stroke mortality caused by low fruit intake. Although the mortality risk showed a decreasing trend, the fruit intake was still low for the Chinese population. Therefore, effective strategies and global awareness are essential to improve the current situation of low fruit intake, thereby preventing and reducing the stroke mortality risk caused by low fruit intake in China.

Province-specific alcohol-attributable cancer deaths and years of potential life lost in China

ObjectiveCancer is a major cause of death in China. As alcohol drinking, a risk factor of cancer, is common in China, we aimed to estimate the alcohol-attributable cancer deaths and years of potential life lost (YPLL) across all provinces in China. MethodsWe estimated the proportion of cancer deaths and YPLL attributable to alcohol consumption at the province level. Population attributable fraction (PAF) was calculated based on: 1) prevalence of alcohol consumption, obtained from the China National Nutrition and Health Survey 2002; 2) dose-response relative risks (RRs) of alcohol consumption and site-specific cancer, extracted from published meta-analyses; 3) cancer mortality data, originated from the National Program of Cancer Registry 2013. ResultsWe estimated that 98,306 cancer deaths were attributable to alcohol consumption and accounted for 4.56 % of the total cancer deaths in China in 2013. Of these deaths, a total of 919,741.57 person-years premature loss of life was caused. Both overall PAF and average YPLL per 100,000 individuals were much higher in men than that in women (7.01 % vs. 0.33 % and 130.55 vs. 4.45, respectively). At the province level, overall PAF ranged from 2.14 % (95 % CI: 1.40 %–2.87 %) in Shanghai to 6.56 % (95 % CI: 4.06 %–9.05 %) in Anhui and the average YPLL per 100,000 individuals ranged from 10.97 in Tibet to 106.52 in Shandong. ConclusionsCancer burden attributable to alcohol consumption varied across provinces in China. Province-level approaches are warranted to decrease alcohol consumption and reduce the alcohol-related cancer burden.

Abstract 12944: Geographical Variations in Cardiovascular Health in China: A Nationwide Population-based Survey of 74,771 Adults

Background: Cardiovascular disease is the leading cause of death in China. Objectives: We aimed to evaluate the levels of cardiovascular health among Chinese adults and to understand the geographic patterns based on a nationally and provincially representative survey. Methods: In 2015, a total of 74,771 respondents aged ≥ 20 years with no history of cardiovascular disease were randomly sampled from 298 counties/districts of 31 provinces in mainland China and were interviewed. Seven metrics, including smoking, body mass index, physical activity, diet, total cholesterol, blood pressure, and fasting glucose, were determined. Ideal cardiovascular health was defined as the simultaneous presence of all metrics at the ideal level. A score ranging from 0 to 14 was calculated as the sum of all seven metrics for each province. Scores for four health behaviors and four health factors were also calculated. Results: The age-adjusted prevalence of ideal cardiovascular health was only 1.13% among Chinese adults above 20 years old in 2015 (0.50% among men and 1.77% among women; 1.63% among urban residents and 0.68% among rural residents). The age-adjusted prevalence varied greatly across provinces, ranging from 0.05% in Qinghai to 2.97% in Heilongjiang. Ideal diet (7.4%) was the least common among seven cardiovascular health metrics and ideal blood pressure (32.2%) was the second least one. We also saw significant heterogeneity among provinces in age-adjusted cardiovascular health score, health behavior score, and health factors score. In all provinces, women had higher scores than men for cardiovascular health, health behaviors and health factors. Differences in cardiovascular health and health behavior scores between urban and rural areas were associated with levels of socio-economic development. Conclusions: Strategies for addressing poor cardiovascular health require geographic targeting and localized consideration.

The association between sleep duration, napping, and stroke stratified by self-health status among Chinese people over 65years old from the China health and retirement longitudinal study.

Stroke is a major cause of death in China. This study aimed to investigate the association between sleep duration (nighttime sleep and daytime napping) and stroke in elderly Chinese individuals with self-reported health status. A total of 4785 Chinese adults over 65years from the 2011 China Health and Retirement Longitudinal Study (CHARLS) were included. Binary logistic regression was used to estimate odds ratios and 95% confidence intervals of the association between sleep duration and stroke stratified by self-reported health status. A significant association between short sleep duration (<7h per day) and the risk of stroke (aOR = 2.05; 95% CI 1.31-3.19), after controlling for sociodemographic characteristics, lifestyle factors, health status, and comorbidities. There was no significant association between short and long sleep duration and stroke in the individuals who reported good general health status. However, in individuals who reported poor health status, short sleep duration (aOR = 2.11; 95% CI 1.30-3.44) and long sleep duration (aOR = 1.86; 95% CI 1.08-3.21) were significantly associated with increased risk of stroke, compared with normal sleep duration (7-8h per day). Disability was significantly associated with stroke in both self-reported good and poor health groups. Rural residence was significantly associated with a lower risk of stroke among individuals who reported poor health status. Both short and long sleep duration were significantly associated with stroke among individuals who reported poor health. Stroke prevention should be focused on elderly individuals who believe that they have health problems.

Effects of state-led suburbanization on traffic crash density in China: Evidence from the Chengdu City Proper

Road crashes have become a leading cause of death in China. Although enormous efforts have been exerted to determine the factors that affect individual crash incidents, neighborhood-level crash incidence in Chinese cities has not been sufficiently analyzed. This study fills this gap by quantifying the effects of built environment factors on neighborhood-level automobile-involved crash density (NACD) in urban China and identifying its mediators and mediating effects. In American suburbs, urban sprawl is widely recognized to render neighborhoods unsafe for residence, thus leading to a high crash incidence. This study compares the characteristics of built environments between inner-city neighborhoods and the new neighborhoods that have been developed through China’s state-led suburbanization since 2008 to reveal how this suburbanization provides a safer neighborhood environment. A structural equation model is used to examine the relationships among suburbanization, built environment factors, and NACD in the city proper of Chengdu, the largest metropolis in southwest China. Thus, this study contributes new empirical evidence to the debates over urban designs that are safest for traffic. Moreover, this study enriches our understanding of different sociospatial consequences between American-style urban sprawl and China’s state-led suburbanization.

A Novel Dried Blood Spot Detection Strategy for Characterizing Cardiovascular Diseases.

Cardiovascular diseases (CVDs) are the leading cause of death in China. Conventional diagnostic methods are dependent on advanced instruments, which are expensive, inaccessible, and inconvenient in underdeveloped areas. To build a novel dried blood spot (DBS) detection strategy for imaging CVDs, in this study, a total of 12 compounds, including seven amino acids [homocysteine (Hcy), isoleucine (Ile), leucine (Leu), valine (Val), phenylalanine (Phe), tyrosine (Tyr), and tryptophan (Trp)], three amino acid derivatives [choline, betaine, and trimethylamine N-oxide (TMAO)], L-carnitine, and creatinine, were screened for their ability to identify CVD. A rapid and reliable method was established for the quantitative analysis of the 12 compounds in DBS. A total of 526 CVD patients and 200 healthy volunteers in five provinces of China were recruited and divided into the following groups: stroke, coronary heart disease, diabetes, and high blood pressure. The orthogonal projection to latent structures-discriminant analysis (OPLSDA) model was used to characterize the difference between each CVD group. Marked differences between the groups based on the OPLSDA model were observed. Based on the model, the patients in the three training sets were mostly accurately categorized into the appropriate group. In addition, the receiver operating characteristic (ROC) curves and logistic regression of each metabolite chosen by the OPLSDA model had an excellent predictive value in both the test and validation groups. DBS detection of 12 biomarkers was sensitive and powerful for characterizing different types of CVD. Such differentiation may reduce unnecessary invasive coronary angiography, enhance predictive value, and complement current diagnostic methods.

Geographical variations in cardiovascular health in China: A nationwide population-based survey of 74,726 adults

BackgroundCardiovascular disease is the leading cause of death in China. The aim of this study was to evaluate the levels of cardiovascular health among Chinese adults and to understand the geographic pattern of cardiovascular health. MethodsIn 2015, a total of 74,726 respondents aged ≥ 20 years with no history of cardiovascular disease were randomly sampled from 298 counties/districts of 31 provinces in mainland China and were interviewed. Seven metrics, including smoking, body mass index, physical activity, diet, total cholesterol, blood pressure, and fasting glucose, were determined. Ideal cardiovascular health was defined as the simultaneous presence of all metrics at the ideal level. A score ranging from 0 to 14 was calculated as the sum of all seven metrics for each province. Scores for cardiovascular health behaviors (smoking, body mass index, physical activity and diet) and those for cardiovascular health factors (smoking, total cholesterol, blood pressure, and fasting glucose) were also calculated. FindingsThe mean age was 44.4 ± 15.9 years, and 49.3% were women. The age-sex-standardized prevalence of ideal cardiovascular health was universally poor, ranging from 0.02% [95% confidence interval (CI): 0%, 0.05%] in Tibet to 2.76% (95% CI: 0.45%, 5.07%) in Heilongjiang. Ideal diet (7.1%) was the least common factor of the seven metrics in each province and varied considerably across provinces. Other component metrics of ideal cardiovascular health were also spatially patterned. In all provinces, women had higher scores than men for cardiovascular health, health behaviors and health factors. Differences in cardiovascular health and health behavior scores between urban and rural areas were associated with levels of socio-economic development. InterpretationStrategies for addressing poor cardiovascular health require geographic targeting and localized consideration. FundingThis research was supported by National Key R&D Program, the Shenzhen Strategic Emerging Industry Development Special Fund, and the Fund of "Sanming" Project of Medicine in Shenzhen.

Analysis of lifetime death probability for major causes of death among residents in China

BackgroundCumulative mortality rate and cumulative mortality risk are two commonly used indicators to measure the impact and severity of diseases. However, they are calculated during a defined life span and assume the subject does not die from other causes. This study aims to use a new indicator, lifetime death probability (LDP), to estimate the lifetime death probabilities for the top five leading causes of death in China and explore the regional differences and trends over time.MethodsLDPs were calculated using a probability additive formula and abridged life tables.ResultsIn 2014, LDPs for heart disease, cerebrovascular disease, malignancy, respiratory disease, and injury and poisoning were 24.4, 23.7, 19.2, 15.5, and 5.3%, respectively. The LDPs for heart disease and malignancy increased by 7.3 and 0.5%, respectively, compared to those from 2004 to 2005. In contrast, the LDPs for cerebrovascular and respiratory disease decreased by 1.0 and 3.9%, respectively, compared to those in 2004–2005. Across the eastern, central and western regions, malignancy had the highest LDP in the eastern region, cerebrovascular and heart diseases in the central region, and respiratory diseases, and injury and poisoning in the western region.ConclusionsLDP is an effective indicator for comparing health outcomes and can be applied for future disease surveillance. Heart disease and malignancy were the two most common causes of death in China, but with regional differences. There is a need to implement targeted measures to prevent chronic diseases in different regions.

Propofol suppresses hepatocellular carcinoma by inhibiting NET1 through downregulating ERK/VEGF signaling pathway

Hepatocellular carcinoma (HCC) is the leading cause of tumor death in China with high mortality since its strong metastatic potential. Currently, treatment against advanced HCC is poorly efficient and thus screening new drugs to prevent the HCC invasion is of great significance to improve the survival rate of patients with HCC. From the results of this study, we concluded that propofol, a widely used anesthetics could prevent the proliferation by MTT assay. The scratch wound and invasion assays showed that migratory property and invasiveness in HCC cells SMMC-7721 was inhibited by propofol. This process was probably mediated by NET1 since NET1 overexpression offset the repressive effect of propofol on the invasiveness and migratory ability of SMMC-7721 cells. Furthermore, propofol treatment also reduced p-ERK1/2 and VEGF level by western blot analysis. Similar observation was found when NET1 was silenced. Thus, the results of this study provided valuable clinical therapy potential of propofol against liver cancer. We also disclosed molecular mechanism underlying the regulation of invasion and migration in HCC cells by NET1.

Cancer registration in China and its role in cancer prevention and control.

Cancer has become a leading cause of death in China, with an increasing burden of cancer incidence and mortality observed over the past half century. Population-based cancer registries have been operating in China for about 60 years, and, in 2018, their role has expanded to include the formulation and evaluation of national cancer control programmes and the care of patients with cancer. The purpose of this Review is to provide an overview of the key milestones in the development of cancer registration in China, the current status of registry coverage and quality, and a description of the changing cancer profile in China from 1973 to 2015. This Review is a comprehensive and updated review on the development of population-based cancer registries in China over a 60-year time span. We highlight some aspects of cancer control plans that illustrate how cancer registration data have become central to the identification of health priorities for China and provide a means to track progress in cancer control for the country.

HOXC10 upregulation confers resistance to chemoradiotherapy in ESCC tumor cells and predicts poor prognosis.

Esophageal squamous cell carcinoma (ESCC) is a malignant disease and is a common cause of death in China. By performing an integrative study investigating public databases and clinical samples collected by our group, we found that HOXC10 (homeobox C10) is upregulated in ESCC tumor tissues compared with nontumor tissues and that the upregulation of HOXC10 is correlated with the poor prognosis of patients with ESCC. The enforced expression of HOXC10 promoted ESCC cell proliferation in vitro and in vivo. Our study revealed that HOXC10 could bind the promoter region of human Erb-b2 receptor tyrosine kinase 3 (ERBB3/HER3) and activate the PI3K/AKT pathway. In addition, by immunoprecipitation and mass spectrometry analysis, we found that HOXC10 could bind X-ray repair cross complementing 6 (Ku70) and accelerate the DNA repair mechanism via the nonhomologous end-joining (NHEJ) pathway. We further evaluated HOXC10 expression in ESCC patients receiving adjuvant radiotherapy or platinum-based chemotherapy. The results demonstrate that HOXC10 upregulation predicts the poor prognosis of ESCC patients receiving adjuvant radiotherapy or chemotherapy. Our study reveals that HOXC10 upregulation reflects the poor prognosis of ESCC patients and directs the selection of postoperative therapy regimens.

Efficacy and safety of DCVAC/LuCa Treatment plus standard chemotherapy and TCM in patients with advanced non-small cell lung cancer: A single-arm phase II study.

e21590 Background: Lung cancer remains the leading cause of cancer-related death in China. DCVAC/LuCa is an active autologous cellular immunotherapy consisting of autologous DCs loaded with NSCLC antigens from NSCLC cell lines. SQFZ is a kind of TCM injection commonly uesed for NSCLC, made from Ginseng and Astragalus membranaceus. Intent of this study is to evaluate the efficacy and safety of DCVAC/LuCa plus chemotherapy and TCM in patients with advanced NSCLC and wild type driving gene(EGFR/ALK). Methods: This study consist of screening/leukapheresis/treatment/follow-up period. On the treatment period, chemotherapy started after leukapheresis. Four cycles are recommended with limitation to maximum 6 cycles. Up to 12 subcutaneous doses of DCVAC/LuCa treatment were administrated on the 15th day of chemotherapy cycle every 3 weeks for 4 doses, and continued alone after chemotherapy finishes/stops every 6 weeks for the remaining 8 doses. TCM therapies were administered on the -3 to 3 days of DCVAC/LuCa. After completion of the total 12 doses DCVAC/LuCa or discontinuation of study treatment, patients will be followed up until experienced OS event or till 1 year of survival time. The primary efficacy endpoint included ORR, PFS and survival. Results: 23 pts were included, 19 males and 4 females, median age 63(48-80). Pathological type:16 adenocarcinoma, 5 squamous cell carcinoma and 1 other. 7 Ⅲb and 16 Ⅳ stage. ORR was 17.39%(4/23), DCR was 60.87%(14/23). Median PFS was 10.9 months, median follow-up in surviving patients was 22.3 months, 1-year survival is currently 92.86%, 18-months survival is currently 79.59%. 1 case was diagnosed as acute myelogenous leukemia myelodysplastic syndrome after 9 doses of DCVAC/LuCa. There were no other adverse events related to DCVAC/LuCa treatment TCM therapies in this study. Conclusions: DCVAC/LuCa, combined with standard chemotherapy and TCM had exhibited the potential to improve the survival in patients with advanced NSCLC, and decrease the occurrence of adverse events. But the sample size of this study is small, a further clinical investigation is needed.

An Age-Period-Cohort Analysis of Stroke Mortality Attributable to Low Physical Activity in China and Japan: Data from the GBD Study 1990\u20132016

Stroke is the first and fourth leading cause of death in China and Japan, respectively. Physical inactivity was suggested to be one of the most important risk factors for stroke mortality. Therefore, this study aimed to assess long-term trends in stroke mortality attributable to low physical activity (LPA) in China and Japan during the period 1990–2016. Mortality data were obtained from the Global Burden of Disease Study 2016 (GBD 2016) and were analyzed with an age-period-cohort method. The age-standardized mortality rates (ASMRs) showed declining trends for LPA-attributable stroke mortality. The overall net drift per year was −1.3% for Chinese men, −2.9% for Chinese women, −3.9% for Japanese men, and −5.6% for Japanese women. In both countries, the local drift values were below zero in all age groups. The longitudinal age curves of LPA-attributable stroke mortality were higher in men than in women in all age groups. The period and cohort rate ratios showed similar downward patterns for both sexes, with a faster decline for women than for men. However, the physically active population is still small in both countries. Therefore, policymakers should further promote physical activity as one of the most recommended effective strategies in stroke prevention.

Long non-coding RNA polymorphisms on 8q24 are associated with the prognosis of gastric cancer in a Chinese population.

BackgroundGastric cancer (GC) remains the third leading cause of cancer death in China. Although genome-wide association studies have identified the association between several single nucleotide polymorphisms (SNPs) on 8q24 and the risk of GC, the role of these SNPs in the prognosis of GC in Chinese populations has not yet been fully evaluated. Therefore, this study was conducted to explore the association between long non-coding RNA (lncRNA) polymorphisms on 8q24 and the prognosis of GC.MethodsWe genotyped 726 surgically resected GC patients to explore the association between eight SNPs in the lncRNAs CCAT1 (rs10087719, rs7816475), PCAT1 (rs1026411), PRNCR1 (rs12682421, rs13252298), and CASC8 (rs1562430, rs4871789, rs6983267) transcribed from the 8q24 locus and the prognosis of GC in a Chinese population.ResultsWe found that the patients carrying rs12682421 AA genotypes survived for a shorter time than those with the GG/GA genotype (HR = 1.39, 95% confidence interval (CI) [1.09–1.78]). Compared with the CC/CT genotype, the TT genotype of rs1562430 was associated with an increased risk of death (HR = 1.38, 95% CI [1.06–1.80]). Furthermore, the results also identified the rs1026411 SNP as an independent prognostic factor for poor survival in GC patients. Patients carrying AA/AG variant genotypes had a 36% increased risk of death compared to those carrying the GG genotype (HR = 1.36, 95% CI [1.06–1.74]). These findings suggested that the rs12682421, rs1026411 and rs1562430 SNPs may contribute to the survival of GC and be prognostic markers for GC.
