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 improve the efficiency and standardization of preoperative anemia diagnosis and treatment by establishing a systematic intelligent management platform for preoperative anemia. Methods: A multidisciplinary collaborative model was adopted to develop a preoperative anemia management system that integrates intelligent early warning, standardized treatment pathways, and quality control. The system utilizes natural language processing technology to automatically capture laboratory data and establish evidence-based medical decision support functions. A pre-post study design was employed to compare changes in preoperative anemia screening rates, preoperative anemia intervention rates, reasonable use of iron supplements, and perioperative red blood cell transfusion rates before and after system implementation. Results: After system implementation, the standardization of anemia diagnosis and treatment significantly improved: 1) Screening effectiveness: The anemia screening rate increased to 50.00% (an increase of 27.24%); 2) Intervention effectiveness: The anemia treatment rate rose to 56.30% (an increase of 14.02%); 3) Treatment standardization: The reasonable use rate of iron supplements increased to 55.33% (an increase of 21.02%); the red blood cell transfusion rate decreased to 18.29% (a decrease of 4.07%), and the amount of red blood cell transfusions was reduced by 291 units. Conclusion: This system achieves full-process management of preoperative anemia through information technology, significantly enhancing the standardization of diagnosis and treatment as well as intervention effectiveness, providing an effective solution for perioperative anemia management.

Objective: To investigate the influencing factors for cognitive function among aluminum workers, so as to provide the basis for intervention and prevention of cognitive function among aluminum-exposed populations. Methods: From July to August 2019, male aluminum workers in the electrolytic aluminum workshop of an aluminum factory in Shanxi Province were selected using the cluster sampling method. Demographic information, prevalence of chronic diseases, lifestyle behaviors, night shifts, and sleep quality were collected through questionnaire surveys. Blood aluminum levels were measured using inductively coupled plasma-mass spectrometry. Cognitive function was investigated using the Montreal Cognitive Assessment. Factors affecting cognitive function among aluminum workers were analyzed by a quantile regression model. Results: A total of 142 aluminum workers were surveyed, including 57 workers aged 20 to <40 years (40.14%) and 85 workers aged 40 to 60 years (59.86%). The median blood aluminum level was 38.23 (interquartile range, 21.82) μg/L. The median cognitive function score was 24.00 (interquartile range, 3.00) points. Quantile regression analysis revealed that older age (βQ5=-0.186, 95%CI: -0.269 to -0.102), lower educational level (βQ5=1.933, 95%CI: 1.029 to 2.838; βQ10=1.743, 95%CI: 0.480 to 3.006; βQ50=1.038, 95%CI: 0.141 to 1.935; βQ75=1.006, 95%CI: 0.437 to 1.575; βQ90=1.111, 95%CI: 0.291 to 1.930), smoking (βQ5=-2.056, 95%CI: -3.264 to -0.849), alcohol consumption (βQ5=-1.821, 95%CI: -3.247 to -0.396) and higher blood aluminum level (βQ5=-0.075, 95%CI: -0.110 to -0.040; βQ10=-0.078, 95%CI: -0.127 to -0.029; βQ50=-0.075, 95%CI: -0.110 to -0.040; βQ75=-0.057, 95%CI: -0.079 to -0.035; βQ90=-0.067, 95%CI: -0.099 to -0.035) were associated with cognitive function decline among aluminum workers. Conclusions Educational level and blood aluminum level are the main factors affecting the cognitive function among aluminum workers. Among those with lower cognitive function scores, age, smoking and alcohol consumption are also associated with cognitive function.

Objective:To investigate the interactive effect of mismatch repair (MMR) protein status and adverse clinicopathological features on prognosis of stage Ⅰ-Ⅲ colon cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 650 patients with colon cancer of stage Ⅰ-Ⅲ who were admitted to 7 hospitals in China from January 2016 to December 2017 were collected. There were 963 males and 687 females, aged 62(53,71)years. Patients were classified as 230 cases of MMR deficiency (dMMR) and 1 420 cases of MMR proficiency (pMMR) based on their MMR protein status. Observation indicators: (1) comparison of clinicopathological characteristics between patients of different MMR protein status; (2) analysis of factors affecting the survival outcomes of patients of dMMR; (3) analysis of factors affecting the survival outcomes of patients of pMMR; (4) interaction analysis of MMR and adverse clinicopathological features on survival outcomes. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the Mann-Whitney U test. The random forest interpolation method was used for missing values in data interpolation. Univariate analysis was conducted using the COX proportional risk regression model, and multivariate analysis was conducted using the COX stepwise regression with forward method. The coefficient of multiplication interaction effect was obtained using the interaction term coefficient of COX proportional risk regression model. Evaluation of additive interaction effects was conducted using the relative excess risk due to interaction ( RERI). Results:(1) Comparison of clinicopathological characteristics between patients of different MMR protein status. There were significant differences in age, T staging, the number of lymph node harvest, the number of lymph node harvest <12, high grade tumor between patients of dMMR and pMMR ( P<0.05). (2) Analysis of factors affecting the survival outcomes of patients of dMMR. Results of multivariate analysis showed that T staging, N staging, the number of lymph node harvest <12 were independent factors affecting the disease-free survival (DFS) of colon cancer patients of dMMR ( hazard ratio=3.548, 2.589, 6.702, 95% confidence interval as 1.460-8.620, 1.064-6.301, 1.886-23.813, P<0.05). Age and N staging were independent factors affecting the overall survival (OS) of colon cancer patients of dMMR ( hazard ratio=1.073, 10.684, 95% confidence interval as 1.021-1.126, 2.311-49.404, P<0.05). (3) Analysis of factors affecting the survival outcomes of patients of pMMR. Results of multivariate analysis showed that age, T staging, N staging, vascular tumor thrombus were independent factors affecting the DFS of colon cancer patients of pMMR ( hazard ratio=1.018, 2.214, 2.598, 1.549, 95% confidence interval as 1.006-1.030, 1.618-3.030, 1.921-3.513, 1.118-2.147, P<0.05). Age, T staging, N staging, high grade tumor were independent factors affecting the OS of colon cancer patients of pMMR ( hazard ratio=1.036, 2.080, 2.591, 1.615, 95% confidence interval as 1.020-1.052, 1.407-3.075, 1.791-3.748, 1.114-2.341, P<0.05). (4) Interaction analysis of MMR and adverse clinicopathological features on survival outcomes. Results of interaction analysis showed that the multiplication interaction effect between the number of lymph node harvest <12 and MMR protein status was significant on DFS of colon cancer patients ( hazard ratio=3.923, 95% confidence interval as 1.057-14.555, P<0.05). The additive interaction effects between age and MMR protein status, between high grade tumor and MMR protein status were significant on OS of colon cancer patients ( RERI=-0.033, -1.304, 95% confidence interval as -0.049 to -0.018, -2.462 to -0.146). Conclusions:There is an interaction between the MMR protein status and the adverse clinicopathological features (the number of lymph node harvest <12, high grade tumor) on prognosis of colon cancer patients of stage Ⅰ-Ⅲ. In patients of dMMR, the number of lymph node harvest <12 has a stronger predictive effect on poor prognosis. In patients of pMMR, the high grade tumor has a stronger predictive effect on poor prognosis.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To explore the value of amide proton transfer-weighted (APTw) imaging and intravoxel incoherent motion (IVIM) imaging for diagnosing and evaluating the pathological differentiation of cervix squamous cell carcinoma (CSCC).Methods:This study was a diagnostic trial. Totally 56 patients pathologically diagnosed with CSCC at the First Hospital of Lanzhou University from October 2021 to October 2022 were retrospectively collected, as the CSCC group. And 36 female healthy volunteers who underwent physical examinations at the First Hospital of Lanzhou University from October 2021 to October 2023 were recruited as the control group. CSCC patients were divided into well-moderately differentiated ( n=34) and poorly differentiated groups ( n=22). The region of interest was placed in the lesions of CSCC group and normal cervical stroma of control group, and the quantitative parameters for asymmetric magnetization transfer ratio (MTR asym) of APTw imaging and pure diffusion coefficient (D), false diffusion coefficient (D *) and perfusion fraction (f) for IVIM were obtained. The independent sample t test was used to compare the differences in quantitative parameters between the two groups, the logistic regression model was used to establish combined parameters for the quantitative parameters with statistical significance between the two groups. The receiver operator characteristic curve was used to evaluate the diagnostic efficacy of single quantitative parameters and combined parameters to distinguish the CSCC group from the control group, and the well-moderately differentiated group from the poorly differentiated group in CSCC patients. The area under the curve (AUC) was compared using the DeLong test. Results:There were significant differences in MTR asym, D and f between CSCC group and control group ( t=-9.79, 10.09, 11.35, P<0.001). Also, significant differences were found for MTR asym and D between the well-moderately differentiated and poorly differentiated group ( t=4.11, -3.76, P<0.001). There was no significant difference in other quantitative parameters ( P>0.05). When comparing the CSCC group and control group, the AUC (95% CI) of MTR asym, D, f and combined parameter (MTR asym+D+f) were 0.887 (0.804-0.944), 0.940 (0.871-0.979), 0.968 (0.909-0.993), 0.995 (0.950-1.000). The AUC of the combined parameter was higher than those of MTR asym and D, with statistical significance ( Z=3.07, 2.06, P=0.002, 0.040). When comparing the well-moderately differentiated and poorly differentiated group, the AUC (95% CI) of MTR asym, D, and combined parameter (MTR asym+D) were 0.789 (0.660-0.887), 0.775 (0.644-0.876), 0.852 (0.731-0.932). There was no significant difference between each two AUCs ( P>0.05). Conclusion:The quantitative parameters of APTw and IVIM imaging can be used to diagnose and preliminarily evaluate the pathological differentiation of CSCC. Joint parameters can improve the diagnostic efficiency of CSCC.

Objective To investigate the distribution characteristics of serum sIgE antibodies against four allergenic protein components of egg white in children with egg allergy,and then clarify the clinical application value of single component-resolved diagnostics of egg allergy.Methods Serum samples from 197 children with egg allergy were collected.The levels of serum sIgE antibodies against four major allergenic protein components of egg white,including ovomucin,ovalbumin,ovotransferrin,and lysozyme,were detected by the light-excited chemiluminescence assay(LiCA),and the distribution characteristics of sIgE antibodies were analyzed.Results The positive rates of serum sIgE antibodies against ovalbumin,ovomucin,ovotransferrin,and lysozyme in 197 chlidren with egg allergy were 77.16%(152/197),70.56%(139/197),35.02%(69/197),and 18.27%(36/197),respectively.The positive rate of serum sIgE antibody against both ovomucin and ovalbumin was 30.45%.There was a weak correlation between the levels of sIgE antibodies against egg and the cumulative levels of sIgE antibodies against four allergenic protein components(r=0.266 8,P＜0.05).There were signifi-cant individual differences in the levels of serum sIgE antibodies against four allergenic protein components of egg white in the children with egg allergy.Conclusion There is individual heterogeneity in the levels of serum sIgE antibodies against four components of egg white in the children with egg allergy.The detection of sIgE antibodies against egg white components can distinguish different forms of egg allergies,which is of great value for the accurate diagnosis and precise desensitization of children's egg allergy.

Objective To explore the effect of back Tuina on motor behavior,oxidative stress and in-flammation in rats with chronic fatigue syndrome(CFS).Methods Twenty-four Sprague-Dawley rats were randomly divided into a blank group,a model group and a Tuina group,each of 8,according to a random number table.The CFS rat model was prepared by means of forced weight-bearing swimming combined with chronic stress stimulation in 21 days.After modeling,the Tuina group was given daily 20-minute Tuina for 14 days.The general condition semi-quantitative score,exhaustion swimming time and open field experiment(OFE)distance of all groups were recorded.After the experiment,sam-ples were collected,and the histopathological changes of the vertical spine muscles were observed by hematoxylin and eosin(HE)staining.The cross-sectional area and diameter of muscle fibers were calcu-lated using Image Pro Plus software,and the frequency distribution diagram of cross-sectional area of muscle fibers was processed by using the Origin software.The contents of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and peroxisome proliferator-activated receptor γ-coactivator 1α(PGC-1α)and tumor necrosis factor(TNF)-α,interleukin(IL)-1β,IL-6 in the serum of rats were mea-sured.Results After the intervention,the general condition semi-quantitative score of the Tuina group was significantly lower than the model group(P<0.01),while the exhaustion swimming time and OFE distance were significantly higher than the latter group(P<0.05,P<0.01).(2)HE staining showed that the significant atrophy of erector spinal muscle cells in the model group,was significantly relieved in the Tuina group.(3)Compared with the blank group,the contents of SOD,GSH-Px and PGC-1α in erectus muscles decreased significantly(P<0.01),while those of TNF-α,IL-1β and IL-6 in the se-rum of the model group increased significantly(P<0.01).However,compared with model group,the contents of SOD,GSH-Px and PGC-1α in erectus muscle increased significantly(P<0.05,P<0.01),while those of TNF-α,IL-1β and IL-6 of the Tuina group decreased significantly(P<0.05,P<0.01).Conclusion Tuina in the back can regulate the oxidative stress response,reliever the inflammatory re-sponse and improve the motor behavior of CFS rats.

The nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflammasome is an inflammatory protein complex, and can participate into the inflammatory response. Upon activation, these inflammasomes can lead to Caspase-1 activation, thereby inducing a cascade of inflammatory factor activation and further cell pyroptosis. Excessive activation of inflammasomes will induce the overexpression of inflammatory factors, persistently triggering immune dysregulation and inflammatory chain reactions, even causing severe damage. The recent studies have confirmed a close association between retinal diseases, such as diabetic retinopathy(DR), retinal ischemia-reperfusion injury(RIRI), and proliferative vitreoretinopathy(PVR)with immune dysregulation and inflammatory responses, which is serving as crucial factors in the progression of retinal diseases. This article reviews the NLRP3 inflammasome signaling pathway and its role in the occurrence and development of retinal diseases, in order to provide new ideas for the pathogenesis and prevention of retinal diseases.
