To estimate the incidence and mortality of cervical cancer in China based on the cancer registration data in 2015, collected by the National Central Cancer Registry (NCCR). There were 501 cancer registries that submitted data to the NCCR, whose data were the basis for estimating the incidence and mortality of cervical cancer in China in 2015. After evaluating the data quality, 368 registries’ data were accepted for the analysis and stratified by area (urban/rural) and age group. Combined with data on the national population in 2015, the nationwide incidence and mortality of cervical cancer were estimated. Cervical Cancer cases of 22 cancer registries were applied for temporal trends from 2000 to 2015. The Chinese population census in 2000 and Segi's population were used to calculate age-standardized incidence and mortality rates. An estimated 111,000 new cases were attributed to cervical cancer in China in 2015, accounting for 6.24% of all female new cancer cases in that year in China. The crude rate (CR) of incidence and age-standardized incidence rates by the China standard population (ASIRC) and by Segi's world standard population (ASIRW) of cervical cancer were 16.56/100,000, 11.78/100,000, and 10.86/100,000, respectively. The cumulative incidence rate from birth to 74 years old was 1.15%, whereas the calculation of incidence rates over the truncated age range of 35-64 years by Segi's world standard population (T-ASIRW) was 27.66/100,000. The estimates of cervical cancer deaths were about 33,800 and 3.94% of all female cancer-related deaths in China in 2015, with a crude mortality rate of 5.04/100,000. The age-standardized mortality rates adjusted by the Chinese standard population (ASMRC) and by world Segi's population (ASMRW) were 3.29/100,000 and 3.15/100,000, respectively, with a cumulative mortality rate (0-74 years old) of 0.35%. Both the incidence and mortality were higher in rural than in urban areas. The age-specific cervical cancer incidence significantly increased with age, particularly after age 25 years, and peaked at 50–54 years old, whereas age-specific mortality increased rapidly after 35 years old, peaking at 80–84 years old. The age-standardized incidence rates increased by about 8.6 (95% CI: 6.9, 10.3) per year during the period of 2000−2015. The age at diagnosis of patients with cervical cancer tended to be younger. In rural areas, the mean age at diagnosis decreased about 3.22 years from 2000 to 2015 (β = –0.33, P < 0.001). China has a high burden of cervical cancer and important disparities among different regions. Especially in the middle and western areas and rural areas, cervical cancer is a serious issue in women's health, and prevention strategies need to be enhanced. Prevention and control strategies need to be enhanced and implemented with reference to local status, such as human papillomavirus (HPV) vaccination and screening programs.

Paraoxonase 1 gene (PON1) polymorphisms and dietary vegetable and fruit intake are both established determinants of ischemic stroke (IS). However, little is known about whether these factors jointly influence the risk of IS. We analyzed the main effects of PON1, as well as the interactions between PON1 and dietary vegetable or fruit intake with the risk of total IS and its subtypes in a family-based case-control study conducted among 2158 Chinese participants (1007 IS cases and 1151 IS-free controls) from 918 families. Conditional logistic regression models, with each family as a stratum, were used to examine the association between rs662 and IS. Gene-diet interactions were tested by including a cross-product term of dietary vegetable or fruit intake by rs662_G allele count in the models. Each copy of the PON1 rs662_G allele was associated with 28% higher risk of total IS (p = 0.008) and 32% higher risk of large artery atherosclerosis subtype (LAA) (p = 0.01). We observed an interaction between rs662 and vegetable intake for both total IS (p = 0.006) and LAA (p = 0.02) after adjustment for covariates. Individuals who carry the rs662_A allele may benefit to a greater extent from intake of vegetables and thus be more effectively protected from ischemic stroke, whereas carriers of the G allele may still remain at greater risk for ischemic stroke due to their genetic backgrounds even when they consume a high level of vegetables. More studies are needed to replicate our findings among other populations.

Background: Geographic variability in esophageal cancer has been reported in China, but data are lacking at the local level. We aimed to investigate changes in disparities in esophageal cancer–related mortality among Chinese counties and whether county-level socioeconomic status was associated with this variation. Methods: We used data from a nationwide survey and population-based cancer registries to calculate esophageal cancer–related mortality rates for 782 Chinese counties for the periods of 1973–1975 and 2015–2017. We performed hotspot analysis to identify spatial clusters. We used a multivariable negative binomial regression model to estimate the associations between county-level socioeconomic factors and mortality. Results: From 1973–1975 to 2015–2017, the age-standardized esophageal cancer–related mortality rate decreased from 27 to 8 per 100,000 person-years in China. By county, 577 (74%) of 782 counties experienced decreasing mortality. Geographic disparities in mortality substantially narrowed, with the gap in mortality rates between 90th and 10th percentile counties decreasing from 55 per 100,000 person-years in 1973–1975 to 16 in 2015–2017. However, clusters of elevated rates persisted across north-central China. Rurality [adjusted mortality rate ratio (MRR) 1.15; 95% confidence interval (CI), 1.10–1.21], per capita gross domestic product (adjusted MRR, 0.95; 95% CI, 0.91–0.98), and percentage of people with a high-school diploma (adjusted MRR, 0.86; 95% CI, 0.84–0.87) in a county were significantly associated esophageal cancer–related mortality rates. Conclusions: China has made substantial progress in reducing esophageal cancer–related mortality and disparities, but the intercounty differences remain large. Impact: Continued efforts are needed to address the geographical and socioeconomic disparities in esophageal cancer.

Soybean is a common food for the Chinese people. We aimed to investigate the risk for brachial ankle pulse wave velocity (baPWV) with inflammatory-related SNPs and soybean. baPWV was measured, and 16 inflammatory-related SNPs located on ADIPOQ, CDH13, SIRT3, SIRT6, CXCL12, CXCR4, NOS1, PON1 and CDKN2B were genotyped in 1749 Chinese participants recruited from various communities. ADIPOQ rs12495941 (GT/TT vs. GG: crude OR = 1.27, p = 0.044) and SIRT6 rs107251 (CT/TT vs. CC: crude OR = 0.74, p = 0.009) were associated with abnormal baPWV (baPWV ≥ 1700 cm/s). After adjustment for conventional environmental risk factors, rs12495941 was associated with abnormal baPWV (GT/TT vs. GG: adjusted OR = 1.43, p = 0.011), but the association between rs107251 and abnormal baPWV was not significant (CT/TT vs. CC: adjusted OR = 0.83, p = 0.173). The interaction between rs107251 and soybean intake for different levels of baPWV was statistically significant (p = 0.017). Compared with a high level of soybean intake, a low level of soybean intake can significantly decrease the risk of abnormal baPWV in individuals of rs107251 CT/TT genotypes (≤100 vs. >100 g/week: adjusted OR = 0.542, p = 0.003). In this study, associations between ADIPOQ rs12495941, SIRT6 rs107251 and baPWV, as well as an interaction between SIRT6 rs107251 and soybean intake for different levels of baPWV were found.
