Objective To integrate and analyze the disease burden of esophageal cancer caused by alcohol consumption in China from 1990 to 2019, along with the differences between genders, and predict the trends in disease burden changes from 2020 to 2029 to improve prevention and treatment strategies. Methods The disease burden of esophageal cancer caused by alcohol consumption in China from 1990 to 2019 was extracted and integrated from the 2019 Global Burden of Disease (GBD) database, and the corresponding trend was analyzed using the Joinpoint regression model with Joinpoint 4.9.1.0 software. The gray prediction model [GM (1, 1) ] was used to forecast the disease burden of alcohol-related esophageal cancer in China from 2020 to 2029. Results In 2019, the leading causes of esophageal cancer in China were tobacco, alcohol, high body mass index, and insufficient fruit and vegetable intake, accounting for the first to fifth positions in esophageal cancer deaths. From a gender perspective, in 2019, the death number and standardized mortality rate for males were 18.97 times and 20.00 times higher than for females, respectively. The disability-adjusted life years (DALYs) and standardized DALYs rate for males were 33.08 times and 24.78 times higher than those for females, respectively, indicating a heavier disease burden of alcohol-related esophageal cancer among Chinese males. From 1990 to 2019, the average annual percentage change (AAPC) in deaths and DALYs due to alcohol-related esophageal cancer in China was 2.08% and 1.63%, respectively, showing a continuous upward trend with statistical significance (P<0.05). The AAPC values for standardized mortality rate and standardized DALYs rate from 1990 to 2019 were –0.92% and –1.23%, respectively, showing a continuous downward trend with statistical significance (P<0.05). The population aged ≥55 years was the main group bearing the disease burden among all age groups from 1990 to 2019. The gray prediction model predicted that by 2029, the overall standardized mortality rate and standardized DALYs rate would decrease to 2.94/100 000and 67.94/100 000, with a greater decline in females than in males. Conclusion Over the past 30 years, the disease burden of alcohol-related esophageal cancer in China has slightly decreased. However, the reduction in disease burden is still lower compared to the overall decline in esophageal cancer burden, and the disease burden for males is significantly higher than for females. Focusing on prevention and treatment for males and the elderly population remains a major issue in addressing alcohol-related esophageal cancer in China.

Objective To assess the evolving disease burden of esophageal and gastric cancers in China from 1990 to 2021, with a focus on gender disparities, and construct a predictive model to forecast disease trends from 2022 to 2031, aiming to optimize targeted prevention strategies. Methods Epidemiological data for esophageal and gastric cancers in China (1990-2021) were extracted from the Global Burden of Disease (GBD) 2021 database. Temporal trends were analyzed using Joinpoint regression (version 4.9.1.0), and future trends were predicted via the GM (1, 1) model under grey system theory. Results From 1990 to 2021, tobacco- and alcohol-attributable burdens of esophageal cancer increased, while tobacco- and diet-related burdens of gastric cancer showed no significant change. Deaths and disability-adjusted life years (DALY) for esophageal cancer rose by 40.61% and 17.89%, respectively; gastric cancer deaths increased by 18.95%, though DALY decreased by 1.22%. Both cancers exhibited significant declines in age-standardized mortality rates (−45.78% for esophageal cancer, −53.29% for gastric cancer) and age-standardized DALY rates (−51.45% for esophageal cancer, −57.58% for gastric cancer). China’s age-standardized mortality and DALY rates for both cancers remained consistently higher than global averages. Males exhibited disproportionately higher burdens than females. Predictive modeling projected continued but decelerating declines in disease burdens for both cancers by 2031. Conclusion Over three decades, China achieves measurable reductions in esophageal and gastric cancer burdens, though gastric cancer burdens remain higher than esophageal cancer. Persistent disparities relative to global levels, elevated male burdens, and aging demographics highlight the urgency for prioritized interventions targeting high-risk populations.

Objectives:To analyze the disease burden and changing trends of non-rheumatic valvular heart disease(NRVHD)from 1990 to 2019 in China. Methods:Based on the Global Burden of Disease 2019 database,we collected data related to NRVHD in China from 1990 to 2019,analyzed the crude incidence rate,crude prevalence rate,crude disability-adjusted life year(DALY),and age-scaled rate of NRVHD during this period,and analyzed the corresponding trends.The grey prediction model GM(1,1)was used to predict the disease burden of NRVHD in China from 2020 to 2029. Results:The crude incidence,crude prevalence,and crude DALY rates of NRVHD increased in China from 7.87/100 000,123.21/100 000,and 9.83/100 000 in 1990 to 22.85/100 000,374.16/100 000,and 11.95/100 000 in 2019;the age-standardized incidence rate and the age-standardized prevalence rate increased from 9.22/100 000 and 169.04/100 000 in 1990 to 15.30/100000 and 262.85/100 000 in 2019 respectively,with females being higher than males;the age-standardized DALY rate declined from 13.43/100 000 in 1990 to 9.07/100 000 in 2019,with females being higher than males.Joinpoint regression model analysis showed an increasing trend in the age-standardized incidence rate and age-standardized prevalence rate,and a decreasing trend in the age-standardized DALY rate(annual average percentage change[AAPC]values of 1.86%,1.72%and-1.66%,respectively),trend of change was statistically significant(all P<0.05).The burden of disease for all age groups from 1990 to 2019 showed an overall increasing trend,and the crude incidence rate,crude prevalence rate and crude DALY rate all increased with age,and the elderly group over 60 years old was the main group of disease burden.The results of the grey prediction model showed that by 2029,the age-standardized incidence rate and age-standardized prevalence rate would increase to 18.51/100 000 and 303.26/100 000,respectively,and the age-standardized DALY rate would decrease to 7.42/100 000. Conclusions:From 1990 to 2019,the age-standardized incidence rate and age-standardized prevalence rate of NRVHD in China showed an increasing trend,and the age-standardized DALY rate all showed a decreasing trend.The disease burden of NRVHD in China remains high.Women and the senior population are the main target groups needing special attention in China,and more targeted prevention and treatment strategies are needed for high-risk population.

Objective To investigate the efficacy and safety of the postoperative analgesia after thoracotomy with different patient-controlled intravenous analgesia (PCIA)medication.Methods One hundred and twenty ASA Ⅰ or Ⅱ patients scheduled for elective thoracic surgery were randomly di-vided into four groups according to different PCIA formula:group S received sufentanil 3 μg/kg;group SD received sufentanil 1.5 μg/kg plus dezocine 0.3 mg/kg;group SF received sufentanil 1.5μg/kg plus flurbiprofen axetil 3 mg/kg;group DF received dezocine 0.3 mg/kg plus flurbiprofen ax-etil 3 mg/kg.For all four goups,the applied medicine was diluted with 0.9% saline to 300 ml,and was infused at 5 ml/h with a bolus dose of 3 ml.The lockout time was set at 1 5 min.The VAS and Ramsay sedation scale were recorded 2,4,8,24,48 h after surgery,respectively.Total pressing times and the side effects were also recorded for the 24 h period after the surgery.Results There were no significant differences of the VAS score at the time 2,4,8,24 and 48 h post surgery of press num-bers within 24 h postoperatively among all groups.The Ramsay sedation scale was significantly high-er at the time 2,4,8,24 h after surgery in group S than those in other three groups (P <0.05).The side effects were more in group S than those in other three groups (P <0.05).Conclusion Compared with sufentanil alone,combination therapy is safer and more effective for analgesia after thoracic sur-gery.With good outcomes and less side effects,it deserves more consideration in clinics.
