Objective:To analyze the cost and structural impact of the new technology"transhysteroscopic mechanical rotary excision of abnormal uterine tissues"on the DRG group of"surgery for intrauterine lesions"under the DRG payment method,and to provide clinical data for supporting the development of the exclusion policy for the new technology and new items.Methods:Cases in which transhysteroscopic mechanical rotary excision of abnormal uterine tissues was used in the gynecology day unit of the Peking Union Medcial College Hospital from March 2022 to November 2023,which were paid for under the DRG group of"surgery for intrauterine pathology",were retrospectively analyzed for the impact of the new technology on the cost and structure of the cases.Results:The price of"transhysteroscopic mechanical rotary excision of abnormal uterine tissues"in the Beijing Medical Service Price Item Specification is 8 000 yuan(Class C out-of-pocket expenses),which is higher than the payment standard of 6 866 yuan for the NE19 group,and the use of this new technology significantly increased the total hospitalization medical cost,the out-of-pocket ratio of the patients and the surgical cost,which led to an increase in the burden of the patients and the loss of the hospitals.Conclusion:"Transhysteroscopic mechanical rotary excision of abnormal uterine tissue"has the advantages of improving patients'prognosis and accelerating recovery,shortening operation time,avoiding intraoperative thermal injuries,and shortening the learning curve of doctors,etc.Policy makers should take into account cost control,patients'prognosis and the development of medical technology,scientifically and prudently formulate the exclusion policy of the new technology,reasonably determine the payment standard,and make good use of the exclusion policy and the payment standard.

Stroke imposes a tremendous burden on patients'families and society due to its high rates of mortality,disability,and recurrence.Advances in neuroimaging technologies have provided critical theoretical foundations for investigating the pathophysiological mechanisms of stroke,as well as enabling early clinical intervention and personalized rehabilitation.This article reviewed the application of five commonly used magnetic resonance imaging(MRI)techniques in acupuncture therapy for stroke,including functional MRI(fMRI)for cerebral blood oxygen metabolism,magnetic resonance spectroscopy(MRS),diffusion MRI(dMRI),perfusion MRI(pMRI),and structural MRI(sMRI).By examining functional,metabolic,structural,and hemodynamic aspects,these imaging modalities offer evidence to validate the multi-target effect and efficacy of acupuncture in stroke treatment.

ObjectiveTo investigate the regulatory effect of icariin （ICA） on transforming growth factor-β₁ （TGF-β₁）/Smad pathway in bone microvascular endothelial cells （BMECs） and the effect on autophagy in BMECs. MethodsBMECs were isolated and cultured， and the cell types were identified by immunofluorescence. Cells were divided into the control group， model group （0.1 g·L^-1 methyl prednisolone）， ICA group （0.1 g·L^-1 methyl prednisolone +1×10^-5 mol·L^-1 ICA）， and TGF-β inhibitor group （0.1 g·L^-1 methyl prednisolone +1×10^-5 mol·L^-1 ICA +1×10^-5 mol·L^-1 LY2157299）. Transmission electron microscopy was used to observe the ultrastructure and autophagosome number of BMECs. Autophagy double-standard adenovirus was used to monitor the confocal autophagy flow generation of each cell. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the gene and protein expression of autophagy in the TGF-β₁/ Smad pathway. ResultsAfter cell separation culture， platelet endothelial cell adhesion molecule （CD31） and von willebrand factor （vWF） immunofluorescence identified BMECs. Transmission electron microscopy showed that the cell membrane was damaged， and the nucleus was pyknotic and broken in the model group. Compared with the model group， the ICA group had complete cell membranes， clear structures， with autophagy-lysosome sparsely distributed. The confocal photo showed that BMECs had autophagosomes and autophagy-lysosomes， and the autophagy expression of the ICA group was similar to that of the blank group. Compared with the blank group， in the model group and the LY2157299 group， autophagosomes and autophagy-lysosomes were barely seen in the autophagy flow. Compared with the blank group， the mRNA and protein expressions of autophagy effector protein 1 （Beclin1） and microtubule-associated protein 1 light chain 3B （LC3B） in the model group were significantly decreased （P<0.01）， and those of ubiquitin-binding protein （p62） were significantly increased （P<0.01）. The mRNA expression of TGF-β₁， Smad homolog 2 （Smad2）， and Smad homolog 3 （Smad3） decreased （P<0.05， P<0.01）. The protein expressions of TGF-β₁， p-Smad2， and p-Smad3 were significantly decreased （P<0.01）. Compared with those of the model group， the mRNA and protein expression of Beclin1 and LC3B in BMECs of the ICA group increased （P<0.01）， and those of p62 significantly reduced （P<0.01）. The mRNA expression of TGF-β₁， Smad2， and Smad3 increased significantly （P<0.01）. The protein expression of TGF-β₁， p-Smad2， and p-Smad3 increased significantly （P<0.01）. Compared with those in the model group， the mRNA and protein expressions of Beclin1， LC3B， and p62 in the inhibitor group were not statistically significant. The expression of key genes and proteins of the TGF-β₁ pathway in the inhibitor group was not statistically significant. ConclusionICA can promote glucocorticoid-induced autophagy expression of BMECs， and its mechanism may be related to activating the TGF-β₁/Smad signaling pathway.

Objective To investigate and analyze the occupational stress levels and influencing factors among radiation workers in China, and provide a reference for alleviating occupational stress and promoting mental health. Methods Using the general situation questionnaire, Effort-Reward Imbalance questionnaire, and radiation protection knowledge questionnaire, a convenience sampling method was adopted to investigate the occupational stress of 243 radiation workers in Liaoning, Fujian, Guangdong, and Xinjiang provinces. The independent samples t-test, one-way analysis of variance, chi-square test, and binary logistic regression were used to analyze the influencing factors. Results The average score of Effort-Reward Imbalance was 0.97 ± 0.22, and 100 (41.15%) radiation workers had occupational stress. There were significant differences in the detection rate of occupational stress among radiation workers of different ages, working years in radiation positions, monthly incomes, daily sleep durations, and daily working hours (P < 0.05). Logistic regression analysis identified daily working hours as a factor contributing to occupational stress. Conclusion The occupational stress among radiation workers in China is relatively severe. It is recommended to pay attention to the associated risks and implement targeted intervention measures to reduce the impact of occupational stress.

Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

Objective To investigate the association between the variability of remnant cholesterol inflammatory index(RCII),a novel composite biomarker,and the risk of stroke,in order to provide a theoretical basis for stroke prevention.Methods A prospective cohort study was conducted on 38 659 Kailuan individuals who took annual physical examinations in 2006,2008,and 2010.These subjects were grouped based on the quartiles of RCII variability,which was represented by standard deviation(SD)and average real variability(ARV),and were followed up every 2 years,with the occurrence of stroke(including ischemic and hemorrhagic strokes),death,or the end of follow-up on December 31,2022 as the endpoints.Kaplan-Meier method was used to calculate the cumulative incidence rate of endpoint events across different groups,and log-rank test was used to compare the difference of cumulative incidence of endpoint events in each group.Multivariate Cox proportional hazards regression model was adopted to analyze the association between RCII variability and risk of stroke.Results Among the 38 659 participants,a total of 2 539 strokes occurred during a mean follow-up period of 11.22±2.26 years.After adjusting confounding factors,when the participants were grouped by the quartiles of RCII-SD,the hazard ratio(HR)for stroke was 1.034(95%CI:0.917～1.167,P=0.584),1.146(95%CI:1.018～1.290,P=0.025),and 1.209(95%CI:1.066～1.370,P=0.003),respectively in the Q2,Q3,and Q4 groups,when compared with the Q1 group(Ptrend<0.05).When they were grouped by the quartiles of RCII-ARV,the HR for stroke was 1.008(95%CI:0.894～1.136,P=0.901),1.109(95%CI:0.986～1.248,P=0.085),and 1.152(95%CI:1.018～1.303,P=0.025),respectively,in the Q2,Q3,and Q4 groups,when compared with the Q1 group.Furthermore,both sensitivity and stratified analyses yielded similar results.Conclusion RCII variability is significantly associated with stroke,and the risk of stroke is gradually increasing with increment of the variability.Countermeasures Relevant authorities can focus on reducing RCII variability as a central objective by establishing regular monitoring mechanism,strengthening lifestyle interventions,and standardizing dietary,exercise,and weight management in order to suppress the index fluctuations.The principle of stable lipid-lowering in medication and optimization of therapeutic regimens with stable efficacy should be emphasized to prevent the risk of additional vascular damage.

OBJECTIVES: To analyze the global disease burden of cervical cancer and the association between screening coverage and the quality of disease management. METHODS: The data of global burden of cervical cancer 2021 and the data of cervical cancer screening 2019 were obtained from IHME Global Burden of Disease (GBD) and the WHO global health observatory, respectively. The age-standardized disease burden index was calculated, the quality of care index (QCI) was determined with principal component analysis, and the correlation between QCI and cervical cancer screening coverage was examined with linear regression analysis by regions and populations. RESULTS: The burden of cervical cancer and the quality of management exhibited significant variability across countries with differing levels of social development. The indicators of cervical cancer burden in China were close to the average level of countries with higher socio-demographic index (SDI). The global QCI was 22.22 (10.50, 35.43), and that of China was 26.30. The global screening coverage rate for cervical cancer was 42% (12%, 86%) and that in China was 31%. After adjusting for the social development level of countries, the coverage level of cervical cancer screening was associated with QCI (β=0.27, P<0.01), with no difference between low and high SDI countries (P>0.05). The association was significantly stronger among 25-30 years old women (β=1.48, P<0.05). CONCLUSIONS There are discrepancies in both the disease burden of cervical cancer and the quality of disease management among countries with different socioeconomic levels, and there is still considerable room for improvement in China. Expanding coverage of cervical cancer screening may be an effective strategy to enhance the management quality of cervical cancer, particularly among younger women where the screening benefits are most pronounced.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective:To investigate the current status of implementing medical insurance performance evaluation in the hospitals of China under the background of China Healthcare Security Diagnosis Related Groups (CHS-DRG) and Diagnosis-Intervention Packet (DIP) payment reform, explore the perspectives and recommendations of key department leaders (e.g., health insurance, medical affairs, pricing, and performance evaluation departments) regarding health insurance performance evaluation, analyze the influencing factors in its implementation, so as to provide references for hospitals to develop and refine health insurance performance evaluation strategies.Methods:A questionnaire was designed and distributed to hospitals across 31 provincial-level administrative regions in China from December 1 to 31, 2023. The survey targeted secondary and tertiary general or specialized hospitals. The main responsible persons from four functional departments, including medical insurance, healthcare, pricing, and performance, were invited to participate in the survey. Descriptive analysis was conducted on the questionnaire data, and the chi-square test was used for differential analysis of unordered categorical variables, while the Wilcoxon rank sum test was used for differential analysis of ordered categorical variables.Results:A total of 761 valid questionnaires were collected. Most respondents were health insurance department leaders (420, 55.19%). Among them, 741 respondents reported that their hospitals used CHS-DRG or DIP payment, with 258 indicating that their hospitals had already developed and implemented health insurance performance evaluation plans. A majority (685, 90.01%) expressed support for such initiatives. Influencing factor analysis revealed that hospital type, level, scope of health insurance management departments, and payment methods might impact the implementation of health insurance performance evaluation ( P<0.05). Conclusions:Few hospitals have currently adopted health insurance performance evaluation, underscoring the urgency to establish a scientific and reasonable evaluation plan as a robust tool for internal hospital management.
