Background With China's socioeconomic development, significant lifestyle changes have occurred among occupational groups, leading to alterations in cardiovascular metabolic risk factors. However, few studies have examined the secular trends of these risk factors in China's working population. Objective To analyze the trends in cardiovascular metabolic risk factors among the occupational population in nine provinces of China from 2009 to 2018, and to explore the associations between different occupational types and these risk factors, along with their clustering patterns, thereby providing evidence for targeted interventions. Methods This study utilized data from the China Health and Nutrition Survey (CHNS) in 2009, 2015, and 2018. The dataset covered 13274 employed individuals aged 18-59 years. Only participants with complete blood test results and physical measurement data were included in the final analysis. The average annual percentage change (AAPC) in the positive rates of risk factors was calculated using Joinpoint regression to analyze temporal trends. Multinomial logistic regression and binary logistic regression models were employed to examine the cross-sectional associations between occupational types (categorized as white-collar workers, agricultural workers, blue-collar workers, service workers, and others) and nine cardiovascular metabolic risk factors and their clustering (defined as having ≥2 risk factors) in 2018. Results A total of 8451 participants were included. From 2009 to 2018, significant increasing trends (AAPC>0, P<0.05) were observed for overweight, obesity, central obesity, borderline elevated triglycerides (TG), borderline elevated to elevated total cholesterol (TC), borderline elevated low-density lipoprotein cholesterol (LDL-C), elevated blood pressure and hypertension, diabetes. The most rapid increases were found for obesity (AAPC=6.07%, 95%CI: 3.42%, 8.88%), hypertension (AAPC=4.10%, 95%CI: 0.62%, 7.77%), and central obesity (AAPC=3.27%, 95%CI: 1.24%, 5.36%). The clustering rate of risk factors increased from 62.3% in 2009 to 73.2% in 2018 (AAPC=1.87%, 95%CI: 1.02%, 2.73%). The cross-sectional analysis in 2018, after adjusting for confounders, showed that compared with white-collar workers, blue-collar workers had a significantly lower risk of overweight (OR=0.67, 95%CI: 0.48, 0.95), central obesity (OR=0.65, 95%CI: 0.45, 0.92), and borderline high TG (OR=0.54, 95%CI: 0.35, 0.82). In contrast, agricultural workers had a higher risk of hypertension (OR=1.76, 95%CI: 1.14, 2.72). Conclusion Between 2009 and 2015, the burden of most cardiometabolic risk factors increases significantly among the Chinese occupational population, with the rate of increase slowing by 2018. Risks vary across occupational types, among which blue- collar workers report lower target outcomes. Targeted interventions focusing on the rapidly increasing risk factors and high-risk occupational groups are recommended.

BACKGROUND: Pancreatic cancer is a lethal malignancy prone to gemcitabine resistance. The single-strand selective monofunctional uracil DNA glycosylase (SMUG1), which is responsible for initiating base excision repair, has been reported to predict the outcomes of different cancer types. However, the function of SMUG1 in pancreatic cancer is still unclear. METHODS: Gene and protein expression of SMUG1 as well as survival outcomes were assessed by bioinformatic analysis and verified in a cohort from Fudan University Shanghai Cancer Center. Subsequently, the effect of SMUG1 on proliferation, cell cycle, and migration abilities of SMUG1 cells were detected in vitro . DNA damage repair, apoptosis, and gemcitabine resistance were also tested. RNA sequencing was performed to determine the differentially expressed genes and signaling pathways, followed by quantitative real-time polymerase chain reaction and Western blotting verification. The cancer-promoting effect of forkhead box Q1 (FOXQ1) and SMUG1 on the ubiquitylation of myelocytomatosis oncogene (c-Myc) was also evaluated. Finally, a xenograft model was established to verify the results. RESULTS: SMUG1 was highly expressed in pancreatic tumor tissues and cells, which also predicted a poor prognosis. Downregulation of SMUG1 inhibited the proliferation, G1 to S transition, migration, and DNA damage repair ability against gemcitabine in pancreatic cancer cells. SMUG1 exerted its function by binding with FOXQ1 to activate the Protein Kinase B (AKT)/p21 and p27 pathway. Moreover, SMUG1 also stabilized the c-Myc protein via AKT signaling in pancreatic cancer cells. CONCLUSIONS SMUG1 promotes proliferation, migration, gemcitabine resistance, and c-Myc protein stability in pancreatic cancer via protein kinase B signaling through binding with FOXQ1. Furthermore, SMUG1 may be a new potential prognostic and gemcitabine resistance predictor in pancreatic ductal adenocarcinoma.

Objective:To investigate the current situation of water-borne endemic fluorosis in Anhui Province, and provide basic data for the adjusting the prevention and control measures.Methods:Using cross-sectional survey method, all villages in the water-borne endemic fluorosis areas were investigated in Anhui Province from 2019 to 2022. In water-borne endemic fluorosis village, the situation of water improvement project and the fluoride level of drinking water were investigated, and dental fluorosis of all children aged 8 - 12 was examined. The criteria for determining the achievement of control targets for water-borne endemic fluorosis in affected counties were based on the "Evaluation Measures for Control and Elimination of Key Endemic Diseases (2019 Edition)".Results:From 2019 to 2022, the rate of water improvement village in water-borne endemic fluorosis areas were 88.47% (1 527/1 726), 100% (1 726/1 726), 100% (1 726/1 726) and 100% (1 726/1 726), respectively. The qualified proportion of water fluoride in water-borne endemic fluorosis villages was 33.84% (584/1 726), 63.09% (1 089/1 726), 70.74% (1 221/1 726) and 74.33% (1 283/1 726), respectively. The prevalence rates of dental fluorosis in children aged 8 - 12 were 25.48% (45 461/178 440), 15.78% (27 959/177 200), 13.68% (23 505/171 880) and 12.66% (23 315/184 200), respectively. The proportion of affected counties that had achieved the control target of water-borne endemic fluorosis was 16% (4/25), 60% (15/25), 36% (9/25) and 40% (10/25), respectively.Conclusions:The water-borne endemic fluorosis areas in Anhui Province have improved the water fluoride qualification rate and reduced the incidence of fluorosis in children through prevention and control measures such as water improvement and fluoride reduction. However, the prevention and control efforts in key areas and counties need to be further improved.

Migraine is a common neurological disorder with a complex pathogenesis that is currently not fully understood;however,the role of mitochondrial function in migraine pathogenesis has recently attracted widespread attention.This review considers the latest research progress on the relationship between mitochondrial dysfunction and migraine,including mitochondrial energy metabolism,oxidative stress,calcium homeostasis,and neuroinflammation.We introduce the epidemiological and clinical characteristics of migraine,and provide a detailed exploration of the key role of mitochondria in these processes.Mitochondrial dysfunction may lead to increased neuronal excitability,abnormal vasoconstriction,and inflammatory responses,thereby inducing migraine.Based on the evidence of mitochondrial involvement in the pathogenesis of migraine,we propose future research directions and potential treatment strategies,with the aim of providing new ideas for the prevention and treatment of migraine.

Objective:This study aimed to clarify clinicopathologic characteristics, postoperative complications, and related risk factors of elderly patients with gastric cancer.Methods:A total of 395 patients(≥65 years old)who underwent radical gastrectomy for gastric cancer in Beijing Hospital from January 2014 to December 2021 were enrolled in this study.The patients were divided into the common elderly group(age<80 years, n=340)and the high-age group(age ≥ 80 years, n=55). Postoperative complications were classified into medical and surgical types.The clinicopathological characteristics and complications were compared between the two groups.Logistic regression models(univariate and multivariate)were used to identify the risk factors for postoperative complications.Results:The common elderly group was 65-79 years old(mean age: 71.5±4.3 years), with 263 male(77.4%); The high-age group was 80-89 years old(mean age: 82.6±2.6 years), with 42 male(76.4%). The comorbidity rate and the number of comorbidities in the high-age group were significantly higher than those in the common elderly group.The American Society of Anesthesiologists(ASA)scores and nutritional risk screening(NRS)2002 scores in the high-age group were significantly higher than those in the common elderly group(both P<0.05), and the activities of daily living(ADL)scores in the high-age group were significantly lower than that in the common elderly group( P<0.001). There were no statistically significant differences in tumor location, degree of differentiation, pathological type, T stage, and N stage between the two groups(all P>0.05). The overall postoperative complication rate in the high-age group was significantly higher than that in the common elderly group(38.2% vs.24.7%, P=0.036); the medical complications were significantly increased in the high-age group(21.8% vs.10.9%, P=0.022), whereas the surgical complications did not increase significantly(25.5% vs.17.1%, P=0.135). Multivariate analysis revealed that the number of comorbidities ≥2( HR=2.502, 95% CI: 1.275-4.911, P=0.008), preoperative NRS 2002 scores ≥5( HR=2.714, 95% CI1.294-5.693, P=0.008), and preoperative ADL scores<100( HR=2.012, 95% CI1.010-4.009, P=0.047)were independent risk factors for medical complications.Additionally, ASA grade ≥ 3( HR=2.586, 95% CI: 1.444-4.632, P=0.001)and proximal or distal gastrectomy( HR=2.397, 95% CI: 1.237-4.574, P=0.009)were independent risk factors for surgical complications. Conclusions:The occurrence of postoperative medical complications in very elderly patients with gastric cancer undergoing radical surgery has increased, while the rate of surgical complications has not increased.Moreover, advanced age itself is not an independent risk factor for postoperative complications.More attention should be paid to medical complications, and the management of commodities and nutritional support should be strengthened during the perioperative period.
