ObjectiveTo evaluate the comprehensive intervention effects of Huangqin Qingre Chubi Capsule (黄芩清热除痹胶囊, HQC) on self-perception of patients (SPP) and immune inflammation in patients with rheumatoid arthritis (RA), and to explore its potential mechanisms. MethodsClinical data of 452 RA patients were retrospectively collected. Patients were divided into a control group (274 cases), treated with conventional western medicine, and an observation group (178 cases), treated with HQC for at least 2 weeks in addition to conventional western medicine. The treatment duration was 2 weeks for both groups. Propensity score matching (PSM) was performed at a ratio of 1∶1 to match patients between groups. SPP including the Chinese version of the short form-36 health survey (SF-36), self-rating anxiety scale (SAS), self-rating depression scale (SDS), visual analog scale (VAS), and Chinese patient-reported index for rheumatoid arthritis (CPRI-RA), as well as immune inflammatory indicators, including erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (anti-CCP), interleukin-6 (IL-6), immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), complement C3, and complement C4, were collected before and after treatment. Spearman correlation analysis was used to assess the relationships between SPP and immune inflammatory indicators. Logistic regression, association rule analysis, and mediation analysis were performed to evaluate the effects and potential pathways of HQC on SPP and immune inflammatory indicators. Network pharmacology was applied to identify the active components and core targets of HQC in the treatment of RA, followed by molecular docking verification. In cell experiments, cells were divided into normal group, model group, 20% medicated serum group, and 80 nmol/L control group. Human synovial fibroblasts (FLS) were cultured with complete medium in the normal group, while human rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) were cultured in the model group. In the 20% medicated serum group, RA-FLS were cultured with medium containing 20% HQC-medicated serum, and in the 80 nmol/L control group, RA-FLS were cultured with complete medium containing 80 nmol/L methotrexate suspension. After 48 h of culture, cell viability was detected by cell counting kit-8 (CCK-8) assay. Levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-10 (IL-10) in the cell supernatant were measured by enzyme-linked immunosorbent assay (ELISA). Protein levels of matrix metalloproteinase 9 (MMP9), transcription factor AP-1 subunit (JUN), vascular endothelial growth factor A (VEGFA), and C-X-C motif chemokine ligand 8 (CXCL8) were detected by Western Blot, and cell migration ability was evaluated using Transwell assay. ResultsAfter PSM, 178 cases were included in each group. After treatment, SF-36 scores increased, while scores of SAS, SDS, VAS and CPRI-RA, levels of ESR, hs-CRP, IL-6, complement C3, and complement C4 levels decreased in both groups; IgG and IgM levels were also reduced in the observation group (P<0.05). Physical functioning (correlation coefficient -0.19, P<0.05) and social functioning (correlation coefficient -0.18, P<0.05) of SF-36 were negatively correlated with hs-CRP, while VAS score was positively correlated with hs-CRP (correlation coefficient 0.19, P<0.05). HQC showed high associations with improvements in multiple indicators of SPP and immune inflammatory, and acted as a protective factor for the improvement of several SPP; hs-CRP and ESR played partial mediating roles in the improvement of SPP induced by HQC (P<0.05). Network pharmacology analysis identified baicalein, quercetin, α1-sitosterol, β-sitosterol, stigmasterol, baicalin, and crocetin as the core active components, and JUN, IL-6, VEGFA, MMP9, IL-1β, and CXCL8 as the core targets. Molecular docking results showed strong binding affinities of quercetin with VEGFA, JUN, MMP9, IL-6, and IL-1β, of baicalin with VEGFA and MMP9, and of wogonin with CXCL8. Cell experiments demonstrated that HQC and methotrexate inhibited RA-FLS viability and migration, reduced levels of IL-1β, IL-6, and IL-8, decreased protein levels of MMP9, JUN, VEGFA, and CXCL8, and increased IL-10 levels (P<0.05). ConclusionHQC can improve SPP in RA by regulating immune inflammatory responses. Its mechanism may be related to multi-pathway and multi-target inhibition of synovial cell inflammation and migration.

BackgroundPersistent cognitive impairment is prevalent among patients with stable schizophrenia. While serum total bile acid (TBA) level in acute-phase patients are known to be associated with cognitive dysfunction, the relationship between serum TBA and multi-dimensional cognitive functions in stable phase patients remains unclear. ObjectiveTo investigate the correlation between serum TBA level and cognitive function in patients with stable schizophrenia, and to evaluate its predictive value for cognitive impairment, thereby providing a serological biomarker for the timely identification and objective assessment of cognitive dysfunction. MethodsA cross-sectional study was conducted on 137 inpatients with stable schizophrenia at The Fourth People's Hospital of Yancheng from March to December 2024. All participants met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). Cognitive function was evaluated using the Chinese Brief Cognitive Test (C-BCT), patients were categorized into four groups: normal cognition (n=28), mild impairment (n=28), moderate impairment (n=47), and severe impairment (n=34). Fasting venous blood samples were collected, and serum TBA level was quantified using an enzymatic cycle assay. Spearman correlation analysis was ultilized to determine the relationship between serum TBA level, overall cognitive function, and specific cognitive domains. Binary Logistic regression model was used (adjusting for covariates such as age, gender, and disease duration) to analyze the impact of serum TBA level on overall and individual cognitive functions. The predictive value of serum TBA level for overall cognitive impairment was evaluated using receiver operating characteristic (ROC) curve. ResultsSerum TBA levels differed significantly among the four groups (H=18.677, P<0.01). Specifically, serum TBA levels in both the moderate and severe cognitive impairment groups were significantly higher than those in the normal cognitive group (adjusted P<0.01). Serum TBA level was positively correlated with the severity grading of overall cognitive impairment (rs=0.354, P<0.05), and negatively correlated with T-scores on the trail making test (rs=-0.328, P<0.05), continuous performance test (rs=-0.247, P<0.05), digit span (rs=-0.265, P<0.05), and symbol coding (rs=-0.221, P<0.05). Binary Logistic regression analysis identified serum TBA level as an independent risk factor for overall cognitive impairment (OR=1.322, 95% CI: 1.021 - 1.713, P=0.034), with a particularly robust predictive ability for impaired information processing speed (OR=1.325, 95% CI: 1.057 - 1.661, P=0.015). The area under ROC curve (AUC) for serum TBA level in predicting overall cognitive impairment was 0.738, with a sensitivity of 60.61% and a specificity of 78.64%. ConclusionIn patients with stable schizophrenia, elevated serum TBA levels are associated with worse overall cognitive function, as well as deficits in information processing speed, attention, working memory, and executive function. Serum TBA serves as an independent risk factor and exhibits moderate predictive value for overall cognitive impairmen,particularly in the domain of information processing speed.

Based on the theory of "sweet-flavored medicinals retaining and restoring body fluid", this paper proposed that the core pathogenesis of hypercoagulable state in malignant tumors is qi deficiency and fluid consumption, blood stasis and vessels stagnation, which evolves dynamically according to the pattern "qi deficiency → fluid consumption → blood stasis". Accordingly, a staged treatment system is established with the general principle of "fortifying the middle jiao, restoring fluid and activating blood circulation". In the initial stage, invigorating the spleen and boosting qi to generate body fluid, targeting the onset of middle jiao deficiency and body fluid consumption; in the middle stage, nourishing yin and unblocking collaterals to facilitate body fluid circulation, addressing the disorder of body fluid transportation and collateral injury caused by internal dryness; in the late stage, consolidating yin and resolving blood stasis to retain body fluid, resolving yin impairment, fluid exhaustion, and binding of stasis and toxin. By regulating body fluid metabolism to improve the hypercoagulable state, this system is intended to provide insights for the prevention and treatment of hypercoagulable state in malignant tumors with traditional Chinese medicine.
