BACKGROUND:Although researchers have noted that fibroblast growth factor receptor 1 shows great potential in rheumatoid arthritis bone destruction,there is a lack of reviews related to the potential mechanisms of fibroblast growth factor receptor 1 in rheumatoid arthritis bone destruction. OBJECTIVE:To comprehensively analyze the mechanism of fibroblast growth factor receptor 1 in bone destruction in rheumatoid arthritis by reviewing the relevant literature at both home and abroad. METHODS:We searched the CNKI database using the Chinese search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,bone cells,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,vascular endothelial cells."PubMed database was searched using the English search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,osteocytes,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,endothelial cells."The search period focused on April 1992 to January 2024.After screening the literature by reading titles,abstracts,and full texts,a total of 82 articles were finally included for review according to inclusion and exclusion criteria. RESULTS AND CONCLUSION:Fibroblast growth factor receptor 1 was found to be widely expressed in bone tissue-associated cells,including osteoblasts,osteoclasts,and osteoclasts.Fibroblast growth factor receptor 1 affects bone remodeling and homeostasis by regulating the function of these cells,as well as promoting the onset and progression of bone destruction in rheumatoid arthritis.Fibroblast growth factor receptor 1 is involved in the inflammatory response of synovial fibroblasts and macrophages and regulates angiogenesis of endothelial cells in synovial tissues.Fibroblast growth factor receptor 1 promotes bone destruction in several ways.Fibroblast growth factor receptor 1 may be a potential causative agent of bone destruction in rheumatoid arthritis and provides a reference for further research on its therapeutic targets.

Objective To propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.

ObjectiveTo understand the mortality trends among residents of Fuling District, Chongqing, before and after theCOVID-19 outbreak, and to provide references for the government to formulate disease prevention and control policies and measures. MethodsData on mortality and population in Fuling District from 2017 to 2022 were collected to analyze population mortality and standardized mortality rates, and to compare the changes in the causes of death by year and before and after the pandemic. ResultsFrom 2017 to 2022, the crude mortality rate in Fuling District showed an upward trend (APC=3.04%, P<0.05), while the standardized mortality rate showed a downward trend (APC=-6.47%, P<0.01). The mortality rate of males was higher than that of females (P<0.05), with different age groups having different causes of death composition. The highest proportion of deaths in 0-year-old group was from infectious diseases, maternal and neonatal diseases, and nutritional deficiencies, the highest proportion of deaths in the 1‒24 age group, with the exception of those aged 5‒9, was from injuries, and the main cause of death for residents aged 25 and above was chronic diseases. The mortality rate of mental and behavioral disorders rose from the 13th to the 9th place. According to the epidemic situation of COVID-19, there were no changes in the top five causes of death among the entire population. The motility rate of endocrine, nutritional and metabolic diseases rose from the sixth to the fifth place in male population, and the motility rate of malignant tumor rose from the 3rd to the 2nd place in female population. ConclusionThere are no changes in the top five causes of death among the entire population of Fuling District before and after the COVID-19 outbreak. Chronic diseases remain the main cause of death. It is necessary to control the risk factors for cardiovascular and cerebrovascular diseases such as hypertension, diabetes, and dyslipidemia, and to curb the rising trend of mortality rates from strokes and acute myocardial infarction. For deaths caused by accidental injuries, targeted health education should be conducted for different populations.

Objective:To investigate the clinical efficacy of 3D printed metal augment or tibial prosthesis for reconstruction of large bone defects in total knee arthroplasty (TKA) and knee revision surgery.Methods:A total of 7 patients (7 knees) with TKA or knee revision who were admitted to the Department of Orthopaedics of the Second Affiliated Hospital of Zhejiang University School of Medicine with large bone defects from July 2018 to December 2023 were retrospectively analyzed, including 4 patients with TKA and 3 patients with knee revision. There were 3 males and 4 females, aged 58.7±7.6 years (range, 54-68 years), 3 patients with left knee and 4 patients with right knee. All the patients had bone defects in the knee joint (AORI type III), 2 cases had bone defects only in the femur, 4 cases had bone defects only in the tibia, and 1 case had bone defects in both the tibia and femur, which were treated with personalized reconstruction using 3D printing. Hip-knee-ankle angles, American Knee Society score (KSS) before and after surgery were compared, and postoperative complications were observed.Results:All patients successfully completed the operation, and the operation time was 189.3±35.5 min (range, 125-240 min). Complex TKA was performed in 4 cases with surgical times of 175, 195, 210, and 240 min, and revision surgery was performed in 3 cases with surgical times of 125, 180, and 200 min, respectively. Intraoperative blood loss was 114±24.4 ml (range, 100-150 ml). Five cases used 3D printed metal augment, and two used 3D printed one-piece tibial components. All patients were followed up for 2, 2, 5, 6, 7, 20, 57 months, respectively. The KSS of the five patients at 3 months postoperatively were 56, 61, 66, 56, and 56 points, respectively, greater than the preoperative scores of 35, 44, 36, 27, and 41 points. The KSS functional scores of the five patients at 3 months postoperatively were 45, 45, 45, 30, and 45 points, respectively, which were greater than the preoperative scores of 30, 30, 15, 20, and 20 points. The hip-knee-ankle angle was 181.8°±3.4° (range, 177.9° to 188.0°) at the final follow-up and 175.8°±12.4° (range, 153.3° to 192.1°) before surgery, with no significant difference ( t=-1.230, P=0.242). At the final follow-up, the 3D printed component was well integrated with the bone surface, the prosthesis was securely positioned, and the force lines of the lower limbs were normal. There were no postoperative complications such as poor wound healing, infection, fat liquefaction, nerve injury, deep vein thrombosis of lower limbs, knee joint stiffness, periprosthesis infection and loosening. Conclusion:Using 3D printed metal augment or tibial prosthesis to reconstruct the huge bone defect in TKA and revision has a satisfactory early clinical effect, satisfactory joint function and good surgical safety.

Objective:To investigate the value of the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS), real-time ultrasound elastography (RTE), and contrast-enhanced ultrasound (CEUS), individually and in combination, in the diagnosis of TBSRTC Ⅲ-Ⅴ thyroid nodules.Methods:A retrospective analysis was performed on 106 patients with TBSRTC Ⅲ-Ⅴ thyroid nodules who were pathologically diagnosed by fine needle aspiration cytology at Bao Ji People's Hospital between February 2022 and December 2023. All patients were assessed using ACR TI-RADS grading, RTE, and CEUS, with postoperative pathological diagnosis serving as the gold standard. The diagnostic effectiveness of ACR TI-RADS, RTE, and CEUS, individually and in combination, for TBSRTC Ⅲ-Ⅴ thyroid nodules was analyzed using the receiver operating characteristic (ROC) curve.Results:There were statistically significant differences in nodule size, blood supply, and proportion of TBSRTC Ⅲ-Ⅴ nodule between the two groups ( χ2 = 4.67, 42.56, 26.09, all P < 0.05), while there was no statistical significance in other general data (all P > 0.05). Of the 106 patients with TBSRTC Ⅲ-Ⅴ nodules, 69 patients were diagnosed with malignant nodules and 37 with benign nodules. The area under the curve (95% CI) of ACR-TIRADS, RTE, and CEUS in identifying malignant nodules were 0.860 [95% CI (0.779-0.920)], 0.712 [95% CI (0.616-0.796)], and 0.788 [95% CI (0.698-0.862)], respectively, with sensitivities of 85.51%, 66.67%, and 73.91%, respectively and specificities of 86.49%, 75.68%, and 83.78%, respectively. The Youden indices were 0.719, 0.423, and 0.577, respectively. Among the three diagnostic methods, ACR TI-RADS had the highest diagnostic efficiency, while RTE had the lowest. Pairwise comparisons in ROC analysis revealed statistically significant differences between ACR TI-RADS and RTE, ACR TI-RADS and CEUS, as well as RTE and CEUS ( Z = 4.22, 3.02, 2.78, all P < 0.05). The ACR TI-RADS + RTE + CEUS combination had the highest sensitivity, specificity, Youden index, and AUC (95% CI) values: 94.20%, 89.19%, 0.834, and 0.917 (95% CI: 0.847-0.962). The RTE + CEUS combination had the lowest values: 76.81%, 78.38%, 0.552, and 0.776 (95% CI: 0.685-0.851). The pairwise comparison results in the ROC curve revealed that significant differences were observed between ACR TI-RADS + RTE and RTE + CEUS, ACR TI-RADS + RTE and ACR TI-RADS + RTE + CEUS, ACR TI-RADS + CEUS and ACR TI-RADS + RTE + CEUS, RTE + CEUS and ACR TI-RADS + RTE + CEUS, and ACR TI-RADS + CEUS and RTE + CEUS ( Z = 3.13, 2.40, 2.16, 4.07, 3.32, all P < 0.05). However, there was no significant difference between ACR TI-RADS + RTE and ACR TI-RADS + CEUS in ROC analysis ( Z = 0.06, P > 0.05). Conclusion:The combined utilization of ACR TI-RADS, RTE, and CEUS offers enhanced information on thyroid nodules, encompassing malignant risk stratification, nodular elasticity, and contrast agent perfusion, thereby aiding in improving the diagnostic precision of TBSRTC Ⅲ-Ⅴ malignant nodules.
