Rheumatoid arthritis （RA） is a chronic autoimmune disease characterized by synovitis as its pathological basis. Although current therapeutic drugs can alleviate symptoms， they are often accompanied by a high risk of side effects. In recent years， the use of flavonoids from traditional Chinese medicine （TCM） in the treatment of RA has garnered significant attention. Studies have shown that the mechanisms by which flavonoids treat RA include inhibiting the release of pro-inflammatory factors， regulating multiple cellular signaling pathways， alleviating oxidative stress， modulating immune system functions， inhibiting bone destruction， and suppressing angiogenesis. Due to their notable anti-inflammatory， antioxidant， and immunomodulatory activities， flavonoids hold promise as potential therapeutic agents for RA. A substantial number of articles in this field have been published. By reviewing Chinese and international literature and applying bibliometric and visual analysis using CiteSpace， this paper explored research hotspots and frontiers in this field， systematically reviewed the structures and anti-RA mechanisms of TCM flavonoids， provided a theoretical basis for their use in RA treatment and clinical applications， and offered new perspectives and references for the discovery of novel TCM-based anti-RA drugs.

Objective To establish a sandwich enzyme-linked immunosorbent assay (ELISA) method for the quantitative detection of Chromogranin A (CHGA) in saliva, and to explore its preliminary application in the testing of saliva samples. Methods Recombinant human CHGA protein was used to immunize BALB/c mice, and monoclonal antibodies (mAbs) were prepared and screened using conventional hybridoma technology. A double-antibody sandwich ELISA detection method was constructed, and the matrix effect of saliva samples was optimized. This method was then applied to detect the concentration of CHGA in the saliva of stressed individuals. Results Twenty-one stable hybridoma cell lines secreting high affinity anti-human CHGA antibodies were obtained. A pair of detection antibodies with the best effect was selected, and the optimal coating concentration was determined to be 10 μg/mL, with the optimal dilution of detection antibodies being 1:32 000. The accuracy and reproducibility of this method were verified, with both intra-batch and inter-batch variation coefficients less than 15×, and the recovery rate between 80× and 120×. The matrix effect was further optimized to make it suitable for saliva sample detection. Saliva samples from individuals in different stress states were collected, and the CHGA levels were detected using the method established in this study, indicating its potential to reflect the intensity of stress. Conclusion A reliable saliva CHGA ELISA detection method has been successfully established, and its potential as a biomarker in stress-related research has been preliminarily explored.

Objective To investigate the relationship between platelet to lymphocyte ratio(PLR)and low-density lipoprotein cholesterol(LDL-C)/high-density lipoprotein cholesterol(HDL-C)ratio with the degree of carotid artery stenosis,neurological deficits,and prognosis in elderly pa-tients with ischemic stroke and carotid artery stenosis.Methods A total of 186 elderly patients diagnosed with ischemic stroke and carotid artery stenosis admitted in our hospital from June 2021 to June 2024 were enrolled in this study.The PLR and LDL-C/HDL-C ratio were collected,and then with median split,they were divided into high and low PLR groups(both 93 cases),and high and low LDL-C/HDL-C groups(both 93 cases).General clinical data were compared between the two pairs of groups.Multivariate logistic regression analysis was used to identify the factors influencing the severity of carotid artery stenosis,neurological deficits,and prognosis.Kendall's Tau-b correlation analysis was employed to assess the relationship of PLR and LDL-C/HDL-C with the degree of carotid artery stenosis and prognosis.Pearson correlation analysis was conduc-ted to evaluate the association of PLR and LDL-C/HDL-C with neurological deficits.Results Sta-tistically differences were observed in the degree of carotid artery stenosis and prognosis between the high and low PLR groups(P＜0.01).The NIHSS score was significantly higher in the high PLR group(P＜0.01).Similar differences were noted between the high and low LDL-C/HDL-C groups in terms of degree of carotid artery stenosis and prognosis(P＜0.01).The NIHSS score was obviously higher in the high LDL-C/HDL-C group(P＜0.01).Multivariate logistic regression analysis showed that PLR and LDL-C/HDL-C were risk factors for the degree of carotid artery stenosis,neurological deficits and prognosis in elderly patients with carotid artery stenosis after ischemic stroke(OR=3.842,95％CI:2.551-5.328,P=0.000;OR=3.604,95％CI:2.402-5.407,P=0.000;OR=2.956,95％CI:1.955-4.471,P=0.000;OR=3.463,95％CI:2.506-4.785,P=0.000;OR=2.878,95％CI:1.991-4.160,P=0.000;OR=3.785,95％CI:2.483-5.768,P=0.000).Kendall's Tau-b correlation analysis showed that PLR and LDL-C/HDL-C were positively correlated with the degree of carotid artery stenosis and the prognosis in these eld-erly patients(P＜0.05).Pearson correlation analysis indicated that PLR and LDL-C/HDL-C were positively correlated with the NIHSS score in the patients(P＜0.05).Conclusion For the elderly ischemic stroke patients with carotid artery stenosis,PLR and LDL-C/HDL-C are related to the prognosis,and can be used to help assess the severities of carotid artery stenosis and neurological deficits.

Objective To explore the effects of high-intensity interval training on fatigue sensation and prognosis in patients with chronic obstructive pulmonary disease(COPD).Methods Sixty patients with COPD treated in outpatient and inpatient departments of our hospital from January to December 2024 were enrolled and randomly divided into a control group and an experimental group using a random number table method,with 30 patients in each group.The control group received conventional rehabilitation training,while the experimental group received high-intensity interval training on the basis of conventional rehabilitation training.Before and after the intervention,the pulmonary function indices(forced expiratory volume in the first second(FEV1),FEV1/forced vital capacity(FVC),diffusing capacity of the lung for carbon monoxide(DLCO)),exercise capacity(6-minute walk test(6MWT),peak oxygen uptake,and load power),subjective fatigue sensation(Fatigue Severity Scale,FSS),and serum level of interleukin-6(IL-6)of the two groups were measured,and the number of acute exacerbations during the 12-week intervention was counted.Results Compared with pre-intervention levels,the post-intervention experimental group showed significant improvements in FEV1 absolute value,percentage of FEV1 to FVC,DLCO,6MWT,peak oxygen uptake,and load power,along with reduced FSS scores and IL-6 levels(P<0.05).In the control group,only load power changed significant-ly(P<0.05),while other indicators showed no significant improvement(P>0.05).The experimental group had fewer acute exacerbations than the control group.Correlation analysis revealed positive correlation be-tween FSS scores and IL-6 levels(r=0.47,P<0.01).Conclusion High-intensity interval training can im-prove fatigue status,pulmonary function,exercise capacity,and inflammatory levels in COPD patients while reducing acute exacerbation risk.Fatigue sensation scores may serve as a potential indicator for assessing COPD disease progression and prognosis.

Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective:To explore the value of color Doppler ultrasound (CDUS) combined with shear wave elastography (SWE) in the diagnosis of thyroid micropapillary carcinoma (PTMC).Methods:The clinical data were retrospectively collected including 51 patients with PTMC (study group) and 49 patients with benign thyroid nodules (control group) who treatment in Maanshan 17 Metallurgical Hospital from October 2020 to December 2022. The clinical data, serum tumor markers, CDUS quantitative parameters, and SWE quantitative parameters were compared between the two groups, the correlation between CDUS, SWE quantitative parameters and serum tumor markers were analyzed by Pearson test, and the diagnostic value of CDUS, SWE quantitative parameters were analyzed by receiver operating characteristic(ROC) curve.Results:The levels of serum carcinoembryonic antigen (CEA), thyroglobulin (TG), galactose hemagglutinin-3 (Gal-3), resistance index (RI), peak systolic flow velocity (PSV), elasticity modulus minimum (E min), elasticity modulus mean (E mean), and elasticity modulus maximum (E max) in the study group were higher than those in the control group: (28.76 ± 4.29) μg/L vs. (15.73 ± 2.96) μg/L, (117.53 ± 25.17) μg/L vs. (49.85 ± 9.64) μg/L, (8.31 ± 2.43) μg/L vs. (3.50 ± 0.82) μg/L, 0.85 ± 0.21 vs. 0.54 ± 0.13, (44.18 ± 8.26) cm/s vs. (22.05 ± 6.49) cm/s, (15.80 ± 1.94) kPa vs. (12.97 ± 1.58) kPa, (38.02 ± 10.39) kPa vs. (23.16 ± 7.83) kPa, (60.13 ± 19.41) kPa vs. (34.65 ± 11.87) kPa, there were statistical differences ( P<0.05). In patients with PTMC, the results of Pearson test showed that, RI, PSV, E min, E mean, and E max were positively correlated with serum CEA, TG, and Gal-3 levels ( P<0.05). The results of ROC curve analysis showed that the area under the curve (AUC) of the combined diagnosis of PTMC by RI, PSV, E min, E mean, and E max was 0.937. Conclusions:CDUS combined with SWE can provide reliable reference for clinical diagnosis of PTMC.
