Objective To systematically analyze the spatiotemporal distribution characteristics and epidemiological trends of tracheal, bronchus, and lung cancer (TBL) disease burden attributed to air pollution globally and in China and the United States from 1990 to 2021, and to assess the patterns of disease burden changes from 2022 to 2031 based on predictive models, providing a scientific basis for formulating targeted TBL prevention and control strategies. Methods Based on the Global Burden of Disease (GBD) 2021 database, we analyzed the disease burden data of TBL attributed to air pollution globally and in China and the United States from 1990 to 2021. R Studio 4.3.2 software was used to analyze the corresponding trends and the Bayesian age-period-cohort (BAPC) prediction model was used to predict the status of the disease burden of TBL attributed to air pollution in the world and in China and the United States from 2022 to 2031. Results In 2021, China had the highest number of deaths and disability-adjusted life years attributed to air pollution (211 400 patients and 4.8947 million person-years), followed by the United States (6 000 patients and 124 300 person-years). The age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life years rate (ASDR) of TBL due to air pollution in the world and in China and the United States showed a decreasing trend. From 1990 to 2021, the ASMR and ASDR of TBL in China due to air pollution were much higher than those in the United States and the global average. In terms of gender, from 1990 to 2021, the disease burden of male patients with TBL attributed to air pollution was much higher than that of female patients. The BAPC prediction model showed that from 2022 to 2031, the ASMR and ASDR of TBL attributed to air pollution showed an upward trend globally, while they showed a downward trend in China and the United States. Conclusion Over the past 30 years, the air pollution-related TBL disease burden in the world and in China and the United States has continued to decline, but China's disease burden is still significantly higher than the global average. The disease burden in men far exceeds that in women, with men and the population aged ≥50 years being high-risk groups. In the future, the global disease trend may reverse and rise, while China and the United States are expected to continuously decline. However, precise prevention and control for high-risk groups remains a key challenge.

Objective To analyze the disease burden and its changing trends of tracheal, bronchus, and lung cancer (TBL) attributable to high fasting plasma glucose (HFPG) in China from 1990 to 2021, and to provide key strategic evidence for the prevention and treatment of TBL. Methods Data related to TBL attributable to HFPG in China from 1990 to 2021 were collected from the Global Burden of Disease Study 2021 database, including mortality rate, disability-adjusted life years (DALYs), age-standardized rates, and other indicators. The Joinpoint regression model was applied to analyze the temporal trends of these indicators. Furthermore, the grey prediction model GM (1, 1) was used to forecast the disease burden of TBL attributable to HFPG in China from 2022 to 2031. Results From 1990 to 2021, the overall disease burden of TBL attributable to HFPG in China showed an upward trend. The total number of deaths, DALYs, crude mortality rate, age-standardized mortality rate, crude DALYs rate, and age-standardized DALYs rate increased from 4700, 121300 person-years, 0.40/100000, 0.61/100000, 10.31/100000, and 14.10/100000 in 1990 to 17400, 386500 person-years, 1.22/100000, 0.82/100000, 27.16/100000, and 17.72/100000 in 2021, with growth rates of 270.21%, 218.63%, 205.00%, 34.43%, 163.43%, and 25.67%, respectively. The increase rates among females were higher than those among males. Analysis using the Joinpoint regression model indicated that both the age-standardized mortality rate and age-standardized DALYs rate exhibited a significant upward trend, with average annual percentage changes (AAPC) of 1.01% and 0.82%, respectively, during 1990-2021 (P<0.05). The disease burden across different age and gender groups generally increased from 1990 to 2021. Mortality and DALYs rates for both males and females rose with advancing age, with elderly individuals and males constituting the primary affected populations. The GM (1, 1) grey prediction model projected continued increases in mortality rate, age-standardized mortality rate, DALYs rate, and age-standardized DALYs rate of TBL attributable to HFPG in China from 2022 to 2031, reaching 1.64/100000, 1.06/100000, 36.45/100000, and 21.81/100000, respectively, by 2031. Conclusion The disease burden of TBL attributable to HFPG remains substantial in China from 1990 to 2021, with males and elderly populations bearing the highest burden. However, the growth rate of disease burden is faster among females compared to males. It is predicted that the disease burden will continue to rise over the next decade, necessitating enhanced focus on early diagnosis and treatment for women and older adults.

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.

The decreasing reliability of forensic medical reports led to the inadequate credibility of forensic science.Therefore,we can improve the credibility of forensic science by improving the reliability of forensic medical reports.The reliability assessment of the forensic medical examination is presented by the final reports.Standardized production of forensic medical reports can not only reflect the reliability of the related forensic service,but also improve such forensic activities by reversing supervision.The standardized preparation of forensic medical reports is the final positive step when improving the reliability of justice.Therefore,it is necessary to improve the standardization of forensic medical reports from the micro perspective,in order to help enhance the credibility of forensic science,which will finally lead to the enhancement of the credibility of the judicial activities.

Objective To evaluate the collateral circulation in patients with acute ischemic stroke(AIS)by using score and grade of prominent cortical vein(PCV)-susceptibility weighted imaging(SWI),and to analyze the relationship between these two imaging features and hemorrhagic transformation(HT).Methods A total of 68 AIS patients admitted in our hospital between Janu-ary 2018 and December 2022 were enrolled in this study.All of them received multimodal brain MRI scanning to observe and analyze the collateral circulation.Then PCV-SWI assessment was performed to obtain PCV score and grade of the collateral circulation.Within 2 weeks,brain MRI scanning was carried out again to evaluate HT,and then the patients were divided into HT group(n=39)and non-HT group(n=29).The relationship between collateral circulation and HT was analyzed.Results The HT group had significantly larger proportion of PVC grade 3 than the non-HT group(P＜0.01).Among the 68 AIS patients,32 had PCV sign with a PCV-SWI score of 0-7,and 36 were identified non-PCV sign with a score of 8-10.There were 27 patients with PCV sign experiencing HT and only 12 with non-PCV sign having HT,with the PCV patients having a higher incidence of HT than the non-PCV patients(P＜0.01).The PCV patients represented a more extensive PCV,and the incidence of HT accounted for 69.23％in them and 30.77％in the non-PCV patients.Of the 68 AIS patients,61 had a diffusion weighted imaging(DWI)-Alberta Stroke Program Early CT Score(ASPECTS)of ≤7 and 7 had a score of＞7,and the incidence of HT was higher in the patients with a DWI-ASPECTS score of ≤7 than those of a score of＞7(97.44％vs 79.31％,P＜0.05).Binary logistic regression analysis showed that PCV grade and NIHSS score at 10-14 d after admission were independent risk factors for HT(OR=2.128,95％CI:1.200-3.774,P=0.010;OR=1.308,95％CI:1.057-1.620,P=0.014),and DWI-ASPECTS score was a protective factor for HT(OR=0.646,95％CI:0.442-0.945,P=0.024).Conclusion DWI-ASPECTS score,PCV grade,and NIHSS score at 10-14 d after admission are independent predictive risk factors for the occurrence of HT in AIS patients in high-altitude areas.Further clin-ical evaluation of PCV signs and infarct size on images is helpful to predict the early occurrence of HT.

Objective To explore the construction and practice of an intelligent prevention and treatment system for venous thromboembolism (VTE) in grassroots hospitals. Methods Based on relevant guidelines and expert consensuses on VTE prevention and treatment, domestic and foreign literature was reviewed. A research and development team composed of clinical experts in VTE prevention and treatment, medical and nursing quality management experts, and information engineers conducted investigations and research in surrounding grassroots hospitals. Through evidence-based research and surveys, the team identified relevant business needs, user needs, and functional requirements of grassroots hospitals, and finally formulated a detailed design plan. The main program of system was written in Java. The interface obtained data from the hospital's data platform through Webservice and view interfaces. To prevent issues of repeated data extraction when multiple applications perform time tasks to assess the same patient during later server usage and expansion, the XXL-JOB distributed task scheduling platform was adopted to handle VTE assessments by medical staff. Results After the clinical application of the intelligent VTE prevention and treatment system, the bleeding risk assessment rate increased from 26.20% at the initial system launch in January 2023 to 83.04% by the end of 2023. In January 2023, the implementation rates of mechanical prevention, pharmacological prevention, and combined prevention for medium-to-high-risk VTE patients were 21.39%, 16.39%, and 5.26%, respectively, which increased to 51.75%, 25.50%, and 25.65% in December 2023. Conclusion The VTE prevention and treatment software system developed by grassroots hospitals can improve development efficiency, enhance the clinical practicality of the system, reduce the workload of medical staff, promote standardization and normalization in VTE prevention and treatment, strengthen closed-loop management of medical quality for VTE as a single disease, and effectively improve the prevention and treatment capabilities and levels of VTE within hospitals.

Objective:To summarize and evaluate the relevant evidence of exercise intervention for adult hemophiliacs patients at home and abroad, and to provide a reference basis for healthcare professionals to individualize exercise programs for adult hemophiliacs.Methods:A computer-based "6s" evidence resource pyramid model was used to systematically search for guidelines, evidence summaries, expert consensuses, systematic reviews and random controlled trials on exercise of adult hemophiliacsin databases such as China Biology Medicine disc, Wanfang Med Online, UpToDate, BMJ Best Practice, PubMed, etc, from the time of creation to January 31, 2023. Quality assessment, evidence extraction and evidence integration of relevant literature was performed by two researchers, with a third researcher adjudicating in case of conflicting opinions. An expert panel meeting was conducted to rate the level of evidence extracted.Results:A total of 15 literatures were included. Among them, 4 guidelines, 2 expert consensuses, 2 systematic reviews, and 7 randomized controlled trials. A total of 28 pieces of best evidence were developed, encompassing 6 aspects of exercise assessment, exercise modality, exercise duration, exercise intensity, precautions, and benefits of exercise.Conclusions:Before exercising, hemophiliacs should be assessed by a multidisciplinary team and an appropriate exercise program should be developed to maintain normal body functions and improve the quality of life of hemophiliacs.

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 association between serum uric acid,pulmonary function and airflow obstruction in Chinese Taiwan healthy subjects.Methods:All the cross-sectional analysis was performed in the population over 40 years old using the physical examination data of Chinese Taiwan MJ Health Resource Center between 1996 and 2016 stratification by gender.The correlation analyses between serum uric acid were done and multivariate Logistic regression analysis was used to explore the effect of serum uric acid on airflow obstruction.Results:A total of 35 465 people were included in the study,in-cluding 16 411 men and 19 054 women.Among them,the serum uric acid concentration of men was higher than that of women,and the serum uric acid concentration of the people with airflow obstruction was higher than that of the people without airflow obstruction.There was a negative correlation between serum uric acid level and the forced expiratory volume in one second(FEV1)and the force vital capacity(FVC)in women(P＜0.05),but in men the correlation didn't exist(P＞0.05).After adjusting for age,education,smoking status,drinking status,work strength,body mass index,history of cough,his-tory of hypertension,history of diabetes,history of dyslipidemia,white blood cells and blood albumin,the airflow obstruction in women was more likely to exist with the serum uric acid elevated(OR=1.12,95％CI:1.02-1.22,P＜0.05).The results showed that women with hyperuricemia were more likely to have airflow obstruction than those without hyperuricemia(OR=1.36,95％CI:1.06-1.75,P＜0.05).There was no correlation between serum uric acid concentration and airflow obstruction in men(OR=1.04,95％CI:0.96-1.13,P＞0.05),also the hyperuricemia and airflow obstruction(OR=1.12,95％CI:0.89-1.39,P＞0.05).Conclusion:There is a negative correlation between serum uric acid and FEV1 and FVC in relatively healthy women,and there is an association between elevated serum uric acid and airflow obstruction in women,but not in men.Further prospective studies are needed to explore whether high serum uric acid level can increase the risk of airflow obstruction.

Objective:To construct and validate a predictive model for the risk of excessive blood loss in pa-tients with ruptured tubal pregnancy,and to provide a basis and tool for the assessment of changes in the condi-tion of patients with ruptured tubal pregnancy.Methods:Clinical data of inpatients with ruptured tubal pregnancy from January 2014 to July 2021 were retrospectively analyzed,who underwent surgical treatment in the Depart-ment of Gynecology,Dongguan Maternal and Child Health Hospital.The pelvic blood volume was categorized into excessive blood loss and non-excessive blood loss groups based on whether the amount of pelvic blood was found to be≥750 ml intraoperatively.Factors influencing the occurrence of excessive blood loss were screened and modeled by univariate analysis,Lasso regression,and multi-factor Logistic stepwise regression.The area un-der the subject working characteristic curve(AUC)was used to evaluate the discrimination of the predictive mod-el,the model's consistency was evaluated by calibration curve and goodness-of-fit test,and the clinical utility of the model was evaluated and validated by the decision analysis curve.Finally,column line plots were drawn.Results:①A total of 386 patients with ruptured tubal pregnancy were included,of whom 124(32.12%)had blood loss≥750 ml.②The optimal predictors for predicting concomitant blood loss in patients with ruptured tubal preg-nancy were screened,including:days of abdominal pain,dizziness,pallor,fatigue,the maximum diameter of para-metrial mass,human chorionic gonadotropin(β-hCG),and hemoglobin(Hb)and the model and the column line graphswere constructed accordingly.③The prediction model AUC was 0.827(95%CI 0.781-0.873);the cut-off value was 0.391,at which point the specificity and sensitivity were 68.55%and 84.35%,respectively,and the AUC validated within the model by resampling was 0.804.Clinical decision curves showed that the threshold probability intervals for the maximum net benefit values ranged from 8.5%-97%,respectively.Conclusions:The constructed prediction model was validated to suggest good discriminatory efficacy and degree of consistency.As a tool,it has clinical application value in predicting the risk of hemorrhage in patients with ruptured tubal pregnan-cy.It can help to determine the occurrence of adverse events such as hemorrhagic shock at an early stage and improve the success rate of rescue treatment.
