Objective: To investigate the trend in incidence and change in age at onset of lung cancer in in Wujiang District, Suzhou City, Jiangsu Province from 2012 to 2021, so as to provide a basis for strengthening targeted prevention and control of lung cancer. Methods: Data of lung cancer incidence from 2012 to 2021 were collected through the Wujiang District Tumor Follow-up Registration Information System. The crude incidence, truncated incidence for 35 to 64 years, and cumulative incidence for 0 to 74 years were calculated. Chinese population-standardized incidence, Chinese population-standardized average age at onset, and Chinese population-standardized incidence proportion were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. The trend in incidence of lung cancer from 2012 to 2021 was evaluated using average annual percent change (AAPC). The trend in the Chinese population-standardized average age at onset of lung cancer from 2012 to 2021 was evaluated using a linear regression model. Results: From 2012 to 2021, the crude incidence, the Chinese population-standardized incidence and truncated incidence for 35 to 64 years of lung cancer in Wujiang District were 84.57/100 000, 37.28/100 000 and 52.10/100 000, respectively, all showing upward trends (AAPC=2.489%, 2.034% and 4.654%, all P<0.05). The cumulative incidence for 0 to 74 years was 4.48%, showing no significant trend (P>0.05). The Chinese population-standardized incidence was higher in males than in females (48.16/105 vs. 26.81/105). The Chinese population-standardized incidence of lung cancer in females showed an upward trend (AAPC=8.174%, P<0.05), while the trend in males was not statistically significant (P>0.05). The crude incidence of lung cancer showed upward trends in the total population and females aged 0-<45 years (AAPC=18.287% and 25.343%, both P<0.05) and those aged 45-<55 age group (AAPC=8.003% and 17.629%, both P<0.05). The Chinese population-standardized average age at onset of lung cancer in total population and females decreased from 67.58 and 65.48 years in 2012 to 60.15 and 54.88 years in 2021, with an average annual reduction of 0.611 and 0.964 years, respectively (both P<0.05). The Chinese population-standardized incidence proportion showed upward trends for the total population and females under 65 years (AAPC=3.879% and 4.639%, both P<0.05). No statistically significant trends were observed in the Chinese population-standardized average age at onset or incidence proportion in males (both P>0.05). Conclusions From 2012 to 2021, the incidence of lung cancer in Wujiang District showed an increasing trend and a trend toward younger onset age. Young and middle-aged females had emerged as a key target population for lung cancer prevention and control.

Objective:To compare the prevalence and progression of subclinical atherosclerosis (SA) in populations with different cardiovascular disease (CVD) risks in China, and clarify the relationship between CVD risk stratification and SA.Methods:All participants were from Beijing Community-Based Cohort of Atherosclerosis. A total of 1 462 participants underwent carotid ultrasound and coronary computed tomography scan during 2008-2009 and 2013-2014. After excluding 191 participants with history of CVD and incomplete baseline data, 1 271 participants were included in final analysis. The 10-year CVD risk for participants were calculated based on the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) equation, and risk stratification was performed. The prevalence and progression of SA was determined by carotid intima-media thickness (cIMT), carotid plaque score and coronary artery calcification (CAC) score.Results:In the participants included in this study, 536 (42.2%), 418 (32.9%) and 317 (24.9%) were classified to have low, intermediate and high 10-year risk, respectively. With the rising level of 10-year risk, the proportion of patients with SA and SA progression increased. In low, intermediate and high CVD risk groups, the proportions of participants with CAC were 16.4%, 36.4% and 52.0% (trend P<0.001); and 15.4%, 36.4% and 53.6% had progression of CAC during follow-up, respectively (trend P<0.001); compared with low-risk group, RRs for CAC progression of intermediate and high-risk groups were 2.316 (95% CI: 1.714-3.129) and 3.322 (95% CI: 2.472-4.463), respectively (trend P<0.001). The trend of relationship between CVD risk stratification and cIMT and carotid plaque progression were consistent with CAC. Conclusions:This current study shows CVD risk stratification is closely related to the prevalence and progression of atherosclerosis in Chinese population. However, many people with low CVD risk have atherosclerotic change in their carotid and coronary artery.

Objectives:This study aims to investigate the association between cumulative fasting blood glucose(FBG)and presence of coronary artery calcification(CAC). Methods:A total of 1 113 participants were recruited from the Beijing Community-based Cohort of Atherosclerosis.Anthropometric measurements and laboratory examinations including FBG were performed in 1998,2008-2009 and 2013-2014 respectively,and coronary CT scan was performed in 2013-2014.Participants were classified into 4 groups according to the level of cumulative FBG(10-year weighted cumulative value of at least 2 FBGs):<50.0 mmol/L group(n=495),50.0-55.9 mmol/L group(n=345),56.0-69.9 mmol/L group(n=176),and≥70.0 mmol/L group(n=97).CAC score>0 was defined as presence of CAC.Multivariable logistic regression model was applied to analyze the impact of cumulative FBG exposure on the risk of CAC,and subgroup analyses were conducted according to factors such as sex and age. Results:The mean age of enrolled participants was(59.7±6.4)years,523(47.0%)were male and 478(42.9%)had CAC.The proportion of subjects with CAC increased with the increment of cumulative FBG.Compared with the<50.0 mmol/L group,the multivariable-adjusted OR(95%CI)for CAC in the 50.0-55.9 mmol/L group,56.0-69.9 mmol/L group,and≥70.0 mmol/L group were 1.43(1.04-1.98),1.92(1.24-2.99)and 2.79(1.35-5.77),respectively(Ptrend<0.05).The risk for CAC increased by 34%per 10 mmol/L increase in cumulative FBG,with OR(95%CI)of 1.34(1.12-1.59).There was no statistically significant difference in the risk of CAC presence for each 10 mmol/L increase in cumulative FBG level between the subgroups(all P≥0.05). Conclusions:Elevated cumulative FBG is a risk factor for the prevalence of CAC,indicating the importance of maintaining healthy FBG in preventing the occurrence of CAC.

A 38-year-old female presented with irregular menstruation and hirsutism that started at age of 16 and diagnosed with polycystic ovary syndrome at age of 29 with elevated testosterone. When treated with ethinestradiol cyproterone tablets, her menstruation returned to normal and androgen levels was not changed. At age of 38 she was referred to the hospital with infertility, a diagnosis of nonclassical 21-hydroxylase deficiency was confirmed using 17-hydroxyprogesterone, dehydroepiandrosterone-sulfate, a cosyntropin-stimulation test and genetic test. This case suggested that nonclassical congenital adrenal hyperplasia should be considered when a patient is presented with oligomenorrhea, hirsutism with hyperandrogenemia and infertility.

Objective To employ high-throughput next generation sequencing (NGS) for analyzing the expression of lneRNAs and mRNAs in donor samples from pediatric living donor liver transplantation and search differentially expressed lncRNAs and drag metabolic gene for individualized guidance of immunosuppressive agents.Methods Between October 2016 and December 2017,10 liver tissue specimens from living donor liver transplantation children were collected and divided into fast and slow metabolic groups (n =5 each) according to the postoperative profiles of drug metabolism.Samples were assayed for high-throughput NGS.Target analysis was used for functional pathways and screening target genes prediction.Results There were differentially expressed 908 mRNAs and 1228 lncRNAs between slow metabolic and fast metabolic groups (P＜0.05).According to the abundance and difference,22 up-regulated and 18 down-regulated mRNAs,13 up-regulated and 24 down-regulated lncRNAs were selected.In addition to CYP3A5,CYP2C19,CYP1A2 and UGT1A1 might affect the metabolism of tacrolimus.At the same time,NONHSAT108617.2 in differemially expressed lncRNAs might regulate the expression of CYP3A5 gene.Conclusions This study has comprehensively analyzed the expression of lncRNAs in donor liver from pediatric liver transplantation.Some differentially expressed drug metabolism related genes may affect tacrolimus metabolism in vivo and thus the postoperative use of immunosuppressive drugs.

Objective: To investigate the association of fruit and vegetable intake with long-term changes of serum lipid levels in middle-aged Chinese and older Chinese population. Methods: The study analyzed the data collected in the 2004 and 2007-2008 cohorts of China Multicenter Collaborative Study of Cardiovascular Epidemiology. Finally, 4 495 participants from 10 groups in various regions of China, who both were followed up in the two cohorts, were included for data analysis. They were aged 41-66 years in 2004. Fruit and vegetable consumption were collected with a simple food frequency questionnaire. The percent changes (Δ%) of serum TC, TG, HDL-C and LDL-C between the two surveys were calculated. Multivariate linear regression models were used to estimate the association of fruit and vegetable intake in 2004 with percentage changes of serum lipid levels during the two surveys. Results: The proportions of individuals who consumed fruits <250, 250-499 and ≥500 g/week were 24.0%, 21.8% and 54.2%, respectively. The proportions of individuals who consumed vegetables <500 and ≥500 g/day were 76.7% and 23.3%, respectively. Compared with fruit intake <250 g/week, the regression coefficients (95% CI) of ΔTC% in 250-499 and ≥500 g/week group were -1.54 (-2.71, -0.37) and -1.77 (-2.79, -0.76). And the regression coefficients (95% CI) of ΔLDL-C% were -2.43 (-4.39, -0.48) and -2.89 (-4.59, -1.19). Compared with vegetable intake <500 g/d, the regression coefficients (95%CI) of ΔTC% and ΔLDL-C% in vegetable intake ≥500 g/d group were -1.01 (-1.95, -0.06) and -1.83 (-3.41, -0.24). However, fruit and vegetable intake had no relationship with ΔTG% and ΔHDL-C%. Conclusion The consumption of fruit and vegetable was inversely related to long-term changes of TC and LDL-C in middle-aged and older population, but no association was found for changes of TG and HDL-C.
