DRG/DIP payment reform has become one of the hot topics of the current government departments,medical institutions,and many scholars.It is an important tool to standardize medical service behavior,control medical service costs,and optimize medical resource allocation.Under the DRG/DIP payment reform system,carrying out fine management of medical re-cords not only conforms to the requirements of the era of high-quality development,but also meets the practical needs of medical insurance payment in the new era,and is also an effective measure to promote the high-quality development of hospitals.This pa-per mainly analyzes the related concepts of medical records management,the causes and problems of carrying out fine manage-ment of medical records,and puts forward solutions,so as to provide reference for the implementation of fine management of med-ical records.

Objective:To analyze the incidence trends of malignant tumors in the elderly population aged over 60 years in Qidong City from 1972 to 2021, as well as to predict the incidence rate for the next decade.Methods:Data were obtained from the Qidong Cancer Registry and Reporting System.The crude incidence rate(CR), age-standardized incidence rate using the Chinese standard population(ASRC), and age-standardized incidence rate based on Segi's world standard population(ASRW)were calculated.Joinpoint regression analysis was conducted using Joinpoint 4.9.1.0 software to determine the average annual percentage change(AAPC)in incidence.Additionally, the ARIMA model implemented in SAS 9.2 software was utilized for time series analysis to forecast incidence trends over the forthcoming 10 years.Results:In Qidong City, a total of 87, 401 malignant tumors were reported in the elderly population.The ASRW increased from 736.85 per 100, 000 in the years 1972-1976 to 1 056.33 per 100, 000 in 2017-2021.Specifically, the ASRW for males rose from 968.56 per 100, 000 to 1 332.75 per 100, 000, while the ASRW for females increased from 550.62 per 100, 000 to 825.44 per 100, 000, with AAPC values of 1.16%, 0.94%, and 1.44% over 50 years(all P<0.001).The incidence trend exhibited an upward trajectory with age, peaking in the 75-79 age group.The AAPC values for the incidence rates in the age groups of 60-64, 65-69, 70-74, 75-79, and those aged over 80 were 0.64%, 0.93%, 0.92%, 2.02%, and 2.44%, respectively(all P<0.001).Among the various cancers, lung cancer, which ranked first, saw an increase in ASRW from 100.87 per 100, 000 in 1972-1981 to 248.84 per 100, 000 in 2012-2021.In contrast, gastric cancer, ranked second, decreased from 216.23 per 100, 000 in 1972-1981 to 103.54 per 100, 000 in 2012-2021.Liver cancer, ranked third, fluctuated from 113.47 per 100, 000 in 1972-1981 to 125.13 per 100, 000 in 2012-2021.Colorectal cancer, ranked fourth, increased from 40.06 per 100, 000 in 1972-1981 to 123.47 per 100, 000 in 2012-2021, while esophageal cancer, ranked fifth, decreased from 63.42 per 100, 000 in 1972-1981 to 28.65 per 100, 000 in 2012-2021.The AAPC values over 50 years for these cancers were 2.25%, -1.89%, 0.36%, 3.13%, and -1.86%, respectively(all P<0.05).Projections indicate that by 2031, the incidence of malignant tumors among the elderly population in Qidong will reach 1 253.84 per 100, 000, with estimates of 1 566.67 per 100, 000 for males and 983.14 per 100, 000 for females. Conclusions:The incidence of malignant tumors among the elderly population in Qidong City is increasing.Common types of cancer in this demographic include lung cancer, gastric cancer, liver cancer, colorectal cancer, and esophageal cancer.Notably, lung cancer, liver cancer, and colorectal cancer are on the rise and should be prioritized in cancer prevention and control efforts.

BACKGROUND: Doxorubicin hydrochloride (DOX) is extensively used in the treatment of various tumors. However, its clinical application is limited due to dose-dependent cardiotoxicity. Currently, few effective strategies exist to mitigate or eliminate DOX-induced cardiomyopathy (DIC). Although ferroptosis is implicated in DIC and its inhibition partially alleviates the condition, the direct targets of DOX in the progression of cardiotoxicity remain unclear. This study aimed to discover the direct targets of DOX in ferroptosis-mediated DIC. METHODS: A DOX pulldown assay was performed to identify proteins specifically binding to DOX in murine hearts, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify candidate proteins. A cardiac injury mouse model was established by DOX treatment. Based on this, multiple ferroptosis biomarkers were detected by flow cytometry, quantitative real-time polymerase chain reaction, western blotting, immunochemistry, etc. Besides, specific activator and inhibitor of signaling pathways were applied to illuminate molecular mechanisms. RESULTS: Glutathione S-transferase P1 (GSTP1) was identified as a DOX target. GSTP1 activity was inhibited in DOX-treated cardiomyocytes, while its overexpression significantly alleviated DIC. Moreover, GSTP1 overexpression inhibited acyl-CoA synthetase long-chain family member 4 (ACSL4)-dependent ferroptosis. Mechanistically, GSTP1 overexpression suppressed c-Jun N-terminal kinase (JNK) phosphorylation, thereby reducing reactive oxygen species (ROS) production and inhibiting ferroptosis in DIC. CONCLUSIONS This study identifies the DOX/GSTP1/JNK axis as a critical pathway mediating ACSL4-dependent ferroptosis in DIC. GSTP1 is highlighted as a potential key mediator of ferroptosis and a promising therapeutic target for DIC.

The method has strong specificity, high sensitivity, simple and rapid experimental operation, and can be used for the determination of the above three genotoxic impurities in pantoprazole sodium.

Objective:To analyze the clinical efficacy of three-dimensional(3D) reconstruction guided uniportal fluorescence thoracoscopic subsegmentectomy for the pulmonary nodules.Methods:We retrospectively analyzed 50 patients with nodules who underwent uniportal fluorescence thoracoscopic subsegmentectomy from December 2021 to February 2024. All patients underwent thin-slice CT scanning and 3D reconstruction preoperatively. 12 patients were given CT-guided hookwire localization preoperatively.The intersegmental plane was identified by fluorescence method.Results:One patient was converted to right upper lobectomy due to no lesion found in S1b. The mean blood loss was(23.4±16.5)ml and the mean operative time was(126.5±38.5)min. The mean duration of postoperative drainage was(2.6±0.8)days. Mean postoperative hospitalization was(4.8±1.8)days. There were 2 cases with postoperative pulmonary infections, including one with encapsulated pleural effusion. There was no air leakage over 3 days, and no death within 30 days after surgery.Conclusion:3D reconstruction guided uniportal fluorescence thoracoscopic subsegmentectomy is a safe and feasible technique for resection of pulmonary nodules in lung subsegments, and surgical indications must be strictly controlled.

Objective:To analyze predictive risk indicators associated with the development of Kümmell's disease (KD) in patients with osteoporotic vertebral compression fractures (OVCFs).Methods:A 1∶1 frequency-matched case-control study design was employed, selecting patients who visited the Department of Spine Surgery at Liuzhou Workers' Hospital from January 2021 to June 2023. Patients were divided into case and control groups based on whether they progressed to Kümmell's disease (KD). Detailed demographic information, comorbidities, and laboratory data were collected, and baseline characteristics of the two groups were compared. Initial predictive variables significantly associated with the target variable were preliminarily screened through univariate analysis. A correlation heatmap was then constructed to assess collinearity among these variables, followed by further selection of potential predictors using the Lasso regression model. Finally, a multivariable logistic regression model was used for the prediction and analysis of KD-related risk indicators.Results:Univariate analysis identified significant predictors of Kümmell's disease, including patient age, bone mineral density, kyphotic Cobb angle, and multiple vertebral fractures. These were included in the subsequent Lasso regression analysis, which identified key predictors with non-zero coefficients: age, bone density, Cobb angle, multiple vertebral fractures, platelet count (PLT), aspartate aminotransferase/alanine aminotransferase (AST/ALT), albumin (Alb), albumin/globulin ratio (Alb/Glb), alkaline phosphatase (ALP), urea (UREA), serum uric acid (SUA), fibrinogen (Fn), blood glucose (BG), and C-reactive protein (CRP). The correlation heatmap revealed the correlation and collinearity risks between these variables, with ALT and AST/ALT showing a high correlation ( r=0.750) and PLT and Alb showing a low correlation ( r=-0.110). Multivariable logistic regression indicated that the presence of multiple vertebral fractures [ OR=2.078, 95% CI (1.072, 4.025), P=0.030], increased Cobb angle [ OR=1.033, 95% CI (1.008, 1.058), P=0.009], elevated levels of ALP [ OR=1.013, 95% CI(1.004, 1.023), P=0.006], and SUA [ OR=1.004, 95% CI (1.000, 1.007), P=0.043] were associated with an increased risk of KD in patients with OVCFs. Conversely, decreased levels of Fn [ OR=0.996, 95% CI (0.992, 0.999), P=0.008] were linked to an increased risk of KD. Conclusion:Multiple vertebral fractures, increased Cobb angle, elevated levels of ALP and SUA, along with decreased levels of Fn, can be used as early-warning indicators to predict whether patients with OVCFs will develop KD. Monitoring these indicators is crucial for the early detection and intervention in these patients.
